If you want to make the scenario more realistic then put more time pressure on Voldemort or put him under more cognitive stress some other way. The hardest part for Voldemort is solving this problem in a short time span and NOT coming up with a solution that foils Harry. The reason experienced soldiers/gamers with little to no intelligence still win against highly intelligent combatants with no experience is that TIME matters when you're limited to a single human's processing power. In virtually every combat situation one is forced to make decisions faster than one can search the solution space. Only experience compensates for this deficit to any measurable degree. In this situation there are several aspects that Voldemort does not have experience with. If he must spends his cognitive resources considering these aspects and cannot draw from experience it makes mistakes much more likely.

This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 114, and also, as a special case due to the exceptionally close posting times, chapter 115.

There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)

Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.

"I wonder how difficult it would be to just make a list of all the top blood purists and kill them.

They'd tried exactly that during the French Revolution, more or less - make a list of all the enemies of Progress and remove everything above the neck..." -Harry's internal monologue, HPMOR Chapter 7

"Amusing, but that was not your first fleeting thought before you substituted something safer, less damaging. No, what you remembered was how you considered lining up all the blood purists and guillotining them. And now you are telling yourself you were not serious, but you were. If you could do it this very moment and no one would ever know, you would." -The Sorting Hat, HPMOR Chapter 10

Well...well I guess it wasn't technically a guillotine. And Harry didn't make a list himself. But Harry did do it, and set it up so no one would ever know.

Other note. Dumbeldore defeated Voldemort. He placed Minerva to intercept any discoveries of Harry and he made Harry swear not to tell anyone about it. This left Voldemort underprepaired against the weapon that got him in the end. Dumbeldore had a million plots going, and this one worked. Sometiems one is all you need.

I dunno, it seems like you could say Dumbledore's Father and Mother defeated Voldemort, they had a child who was intelligent enough to do those things you said. More seriously, it was a causal chain. Pretty much everyone involved was crucial. If I had to give credit to one party in particular it would be the entity or entities which hands out prophecies (I suspect this is Future!Hermione, but we'll see). Voldemort's first defeat was caused by his attempts to fulfill the first in his own way. His second was caused by his attempt to comprehensively thwart the second.
3MathMage
Over/under on there being such entities at all? It's certainly possible that our current understanding of where prophecies come from is incomplete, but the story doesn't seem to have set it up as particularly likely.
2WalterL
Ok, 5 chapters left, I have a , lets call it 70% surety that there is more left than wrapup. 1-3 chapters would be enough for that. I think there will also be a flashforward to whatever the big triumph is. Ending Death, optimizing the world, colonizing space, gaining Root on the Source of Magic, which is stored in the Mirror...
3TobyBartels
An epilogue, as in Rowling's books?
1MathMage
I would say at least 95% certainty that there's more than wrapup left, but it sounds like handing out prophecies is pretty far down on the list of additional things to cover.
2WalterL
I have a sort of uber-theory that's been hanging over me since Harry heard the whisper to meet Hermione Granger on the train, since he felt irrationally certain that Magic was real back in the very first chapters. This theory is that Future!Harry, or a friend, Future!Hermione is the one who most fits the bill, is God. Or Root on the Source Of Magic. The things that are inexplicable, that certainty, those prophecies, are just his the future self protecting its timeline, as it remembers doing, just like Harry writing "Don't mess with time" on his paper. If so, they'll sucessfully take control of reality, and discover that their uber-Time

Pretty sure the Atlantians created the Source. There's probably a dyson sphere in our star cluster providing all the power needed for magic.

If so, then it's too bad that the Pioneer Horcrux didn't manage to make it outside of that sphere before now. Voldemort might have been in for a terrible shock if it had suddenly stopped working!

His irrational certainty is explained by the buried memories of Tom Riddle. I imagine Dumbledore steered him towards Hermione.

I didn't meant to retract the whole thing. Sorry, I'm new to the site and there doesn't appear to be an undo.
0jkadlubo
I would say that the whole thing took about 3 hours (maybe more if the walk to the cemetery took a lot of time), so now that Harry used his last hour, he's about 3 hours before his past self gets the note. He has to occupy that time, and what better way than to try to free Dumbledore? I don't mind him not succeeding - I already have my "as good as possible" ending.
0Jost
In that case, the big explosion would happen about 2 hours before his past self gets the note, which would make the timeline inconsistent, since no such disturbance of the Quidditch match occurred while past!Harry was there. Given that constraint, everything that happened since Harry time-turned five hours back must have taken at least five hours.

Did he actually thwart it or will it happen?

I don't think you can thwart prophecies. Voldemort's efforts to do so were pointless.

After sleeping on it, I'd like to raise two problems I have with the last double-update, and see what you guys think.

1. That Harry would be able to cast Partial Transfiguration in those circumstances does not seem clearly and unambiguously established by the story so far.

(unless I'm missing something, in which case please point it out to me.)

I'm not saying it's wrong that he was able to cast it. I'm saying that as a reader, I couldn't know that in advance, and that's bad for a story.

First we're told that you can't transfigure air. And EY repeatedly insists Harry cannot overcome any limitations of magic in 60 seconds, so that felt like a hint not to look for a spellcasting solution, at least not without regaining some freedom of movement first.

We did get an earlier scene where Harry considers the fact that his wand is showing some minor wear and tear, and seems robust against small loss of wood. So yes, that feels like a hint in the other direction, maybe even fairly strong evidence.

But the thing is, magic in Harry Potter universe is arbitrary in so many ways, like that you have to say "Wingardum Leviosa" and not something else if you want to levitate something. HPMoR draw... (read more)

I mostly agree with the first part, and it's an important reason for which I didn't like the "final exam" concept, there is just too much we don't really know about how HPMOR world works. It's fine from a pure story-telling point of view, because we can assume Harry knows more about it than we do (he's living in it after all, he did read many books about magic, do many experiments, attend to lessons, ...) but it's not fair to ask us to outguess such things. For the second part, I don't really agree. Think about the emotional state of Harry. He got through a very very stressy times, and despite all odds, he won. I must be feeling some euphoria for that. And at the same time, he killed dozens fo people. In self-defense, sure. But he, the anti-deathist just killed dozens of people. In such a situation, the mixing of euphoria of winning against all odds and the horror of having just killed, wondering what the future ethical transhuman civilization would do and think about all that feels totally appropriate to me. It's exactly what I would expect of Harry, the one who (re-)invented True Patronus.
1MarkusRamikin
I concede this. I think I just don't like this part of Harry that much, but that is not the same as saying it's not in character. The rest of my point remains, that after all all the pressure built up in the previous 8 chapters, this one is too relaxed and lacking in precautionary thinking. Is it really fine from a storytelling point of view? I suggest that correct storytelling means making solution-relevant rules clear in advance. Like in Death Note, the plot often hinges on how exactly the notebooks work, but these rules - and how much each character knows about them - are made very clear before they become pivotal. And clearly EY tried to do this, and came close (with the robust-wand thing). I just don't think it quite worked.

https://parahumans.wordpress.com/category/stories-arcs-21/arc-23-drone/23-04/ (edited slightly for spoilers) “I always hated the speeches when I was in school, the preaching in auditoriums, the one-note message. Stuff like saying drugs are bad. It’s wrong. Drugs are fantastic.” “Um,” Fox-mask said. Mrs. Yamada was glaring at me, but she hadn’t interrupted. “People wouldn’t do them if they weren’t. They make you feel good, make your day brighter, give you energy-” “Taylor,” Mrs. Yamada cut in. “-until they don’t,” I said. “People hear the message that drugs are bad, that they’ll ruin your life if you do them once.

It isn’t a mind-shattering moment of horrible when you try that first drug. Or so I hear. It’s subtle, it creeps up on you, and you never really get a good, convincing reason to stop before it ruins your life beyond comprehension. I never went down that road, but I knew a fair number of people who did.”

Do The Impossible, indeed. Looping a thin thread over someone's head several meters away is tricky business. The slightest bit of wind throws it off. And this must be done without moving the wand or betraying the operation through one's facial expression. I can't imagine it being done without the utmost concentration, allowing of course for effort to be expended talking to Voldemort and maintaining mental blocks against any Legilimens among the Death Eaters (recall that in Half-Blood Prince Snape was able to detect spells forming in Harry's mind). This is all done perfectly the first time around. Thirty-six times, plus Voldemort's wrists.

I suppose one can honestly say A Wizard Did It...

Reading the chapters again, I can't help feeling that, while Harry's sudden victory is satisfying from a "we, the fandom, have passed the test" perspective, without that context it is really unnatural. Harry abruptly goes from being utterly emotionally overwhelmed and reeling to the flawless, cold-blooded execution of a perfect plan that fully draws on a number of disparate ideas and abilities.

Edit: Also, I'm far from the first person to say this, but Harry's sudden spike in competence is preceded by Voldemort becoming a hammier, less intelligent villain. His precautions against Harry attempting to escape, and his plans for how to kill him reliably, are reasonably intelligent, but there are a dozen simpler and/or more effective countermeasures he could have taken, starting with something as obvious as getting rid of Harry's wand.

If there were more chapters left to go, I'd put money on "Voldemort let all this happen as part of a greater gambit", but as things stand I'm feeling pessimistic.

I'm not sure what you're trying to say. In most stories that involve a final conflict between a hero and a villain, none of those options apply. The villain is stronger, and is defeated through some combination of circumstances and advantages that allow the hero to bypass that strength or temporarily exceed it (typically through significant effort and/or sacrifice, often prior to the confrontation).
1solipsist
Right, that's what happened in this story: Harry temporarily got the upper hand on Voldemort. Voldemort allowed Harry to get the upper hand. When Voldemort possessed Quirrell's body, he didn't just take over the world over the course of a week. When Voldemort realized that Harry was an existential threat, he didn't relieve Harry of his limbs, mind, and freedom to move outside a little box. Voldemort allowed Harry to be a threat because otherwise there wouldn't have been a story.
[-]Velorien120

Voldemort allowed Harry to be a threat because otherwise there wouldn't have been a story.

The problem is that he did so in a way that feels inconsistent with the rest of the story. Most villains in most stories aren't the type that would relieve their nemesis of his limbs, mind, and freedom to move outside a little box. Sauron didn't seal off the Cracks of Doom, or even post a serious guard around them. The Emperor didn't place the shield generator on Endor in a hidden underground compound guarded by a small army. A great succession of villains have failed to just shoot James Bond. HPMOR!Voldemort would do all of those things, because from the start his extraordinarily high intelligence and skill at what he does have been cornerstones of his character. When he makes a mistake, many readers will assume (and have assumed, usually correctly) that it is a deliberate ploy. Mistakes as bad as what we're seeing here aren't just folly; they verge on character derailment.

As a simple matter of fact, Voldemort is stronger than Harry in basically every way, other than Harry's (incomplete) training in rationality. If Voldemort were a good enough planner, there's no way he could lose; he is smarter, more powerful, and has more ancient lore than any other wizard. If Voldemort were also rational, and didn't fall prey to overconfidence bias / planning fallacy...

Well, you can be as rational as you like, but if you are human and your opponent is a superintelligent god with a horde of bloodthirsty nanobots, the invincible Elder Lightsaber, and the One Thing to Rule Them All, then the story is going to read less like HPMOR, and more like:

"...HE IS THE END OF THE WORLD." Quirinus Quirrell calmly activated the toe ring he had prepared months ago, causing the capsule of sulfuric acid embedded in the top of Harry's skull (placed there earlier by an Imperiused Madam Pomfrey, in case of emergency) to break open and quickly dissolve the other Tom Riddle. Quirrell shook his head in disappointment as he felt the sense of doom diminish and then disappear, but it had to be done. He turned to walk towards the third floor corridor. The End.

4Velorien
Yup. So the solution is not to make your villain a superintelligent god with a horde of bloodthirsty nanobots, the invincible Elder Lightsaber, and the One Thing to Rule Them All to begin with. Eliezer took the risk of setting up an incredibly powerful villain, and it is to his credit as a writer that up until the very end he made us believe that he was capable of writing a satisfying resolution anyway. Frankly, he still might. There are four chapters left, and Eliezer is nothing if not capable of surprising his audience. And as a Naruto fan, he might also have come across Bleach (another of the Big Three shounen series), and learned from its author already having made the exact same mistake.
2Eli Tyre
Ah. But he would want to be more careful than that, because there's a prophecy, and Voldemort got burned the last time a prophecy was involved. So he goes out of his way to tear it apart, by bringing Hermione back, for instance, which required the stone, and having the other Tom swear an unbreakable vow.
1Pongo
There wouldn't have been such a prophecy if Voldemort had been sufficiently rational
2solipsist
Professor Quirrell will always be a step ahead of you, will always outwit you. You cannot beat him in any game. That is the characterization of the Defense Professor. A story cannot start with "You can't beat the Professor Quirrell at any game" and end with "Professor Quirrell has lost the game" without a character break in between.
[-]gattsuru510

Is that what we've seen presented so far?

Dumbledore won during the Battle of the Three Armies. His assault on Azkaban would have gotten him killed (and more seriously, set back his efforts by years) for a stupid communication error, were Harry not willing to risk his own life and invent new magic to save the man. Hermoine outlasted several hours of the Defense Professor's most aggressive psychological attacks possible, using fairly basic deontology. His 'lesson plan' with Ma-Ha-Su in Chapter 16 was bluntly stupid, even if Harry hadn't used the easy way out. In Chapter 35, he fears that Harry has screwed over his plans because of voicing an obvious disagreement that Harry has repeatedly given privately before.

And that's before we get to the stupidity that was enforced by canon : testing multiple novel spells (Horcruxes, however he 'reformated' the young Harry Potter) without sufficient and verified safeties, the highly fractious Death Eaters, the lackluster war with Dumbledore.

Quirrellmort is smart. He thinks ahead. But his fundamental philosophy is still very restricted. As much as he tries to claim otherwise, he's running on distilled Command Push -- we'll note that no De... (read more)

What are you talking about here?

In Chapter 16, Quirrelmort instructed the class in a very simple hex that caused a small amount of pain and no lasting harm called Ma-Ha-Su. He then selects three students, Hermoine, Draco, and Harry Potter, and then requires them to select a student and fire Ma-Ha-Su at them, taking Quirrel and later House points for non-compliance. The comparisons to the Millgram Experiments become explicit in chapter 63. Hermoine refuses, Draco fires on Hermoine, and Harry fires on himself.

Harry explicitly beats Quirrelmort's plans, here : "Yes, quite ingenious, but there was a lesson to be taught and you dodged it." It's not clear he ever gets the intended lesson, given that Quirrelmort seemed to intend to teach Harry to harm Draco on obedient command.

Interestingly, this could have not just failed but have gone horribly wrong for Quirrelmort, and he wouldn't have even understood why. One of the common responses to Millgram-like actions in the last few years of science fiction is to turn on the person giving illegal orders. Harry wouldn't do that because of his upbringing, but other possible Riddle-clones would wanted to fire Ma-Ha-Su on Quirrel... (read more)

I wondered the same thing. The only thing Google gave me that made sense in context was jargon from a Civilization wiki, meaning a style of military command where orders include implementation details: "here's the actions you need to take". The pitfalls of this style are that it places increased cognitive and communications load on the commander, that it can fail to account for local or changing conditions, and that it can lead to poor responsiveness under conditions of imperfect communication. Current management theory (and, I believe, Western military doctrine, though I'm not an expert) favors objective-based orders: "here's the goal you need to accomplish". That leaves implementation details up to subordinates.

Which isn't a problem in HPMOR, because we've been given a number of persuasive reasons why Quirrell wanted Harry alive - he didn't change his mind about this until he heard the prophecy about Harry destroying the world, at which point it seems he decided to kill Harry as soon as he'd used him to obtain the Philosopher's Stone.

Let me have a go at coming up with a dozen:

  • Remove Harry's glasses (which could have been a transfigured anything, and Voldemort had just taught Harry how to dispel transfiguration by mere physical contact)
  • Bind or paralyse Harry, with rope or a Death Eater spell
  • Have a Death Eater Imperius Harry with a command to obey Voldemort and do nothing else
  • Have a Death Eater use a Confundus Charm on Harry to make him trust Voldemort and not look for ways to escape
  • Blind Harry - he doesn't need his eyes to tell Voldemort his secrets, just his ears and tongue
  • On the same principle, Voldemort could happily dismember him, as long as magic was used to prevent death from blood loss or shock, and distraction from pain
  • Drain Harry of magic by forcing him to cast innocuous spells
  • Use illusions to disguise the number and location of the Death Eaters so that Harry is unable to come up with targeted countermeasures against them (and so are any unexpected rescuers)
  • Cast a spell on Hermione as a dead man's switch - something that will not permanently hurt/kill her unless Harry does something to incapacitate Voldemort and prevent him from dispelling it in time (not

I posted this as part of my review. I think it explains the wand thing. As so often happens in real life, we don't see the workings of mind that lead to every decisive factor in an outcome. In real life, we get to the end of a problem and often don't know why a particular mistake was made. ...

A small disturbance dwelt in my mind for these days, for I had concluded that Eliezer had already contrived a clever solution for Harry, sealed off all other such pathways, and that a strong indicator of what that contrived plan was, was that Voldemort left Harry with his wand after the Vow. Curious, that, oui? Voldemort specifically forbade Harry to raise his wand, and told his servants to attack him in a flurry of eclectic attacks, the mere thought of which would inevitably have an emotional effect on Harry, clouding his mental acuity. Since, Voldemort has in his consciousness that Harry has his wand, and has no reason to let him hold it, the clear explanation is that Eliezer could only think of a way for Harry to win if he had his wand, so he made Voldemort make a stupid mistake, it was the best he could do. Still quite good; I did not begrudge him it.

Since victory depends upon the wand, an... (read more)

If letting Harry have the wand is out of character as a mistake, but in character as a test, not only does that mean that letting him have the wand is a test, it also means that Harry should be able to figure out that letting him have the wand is a test. This ruins the usefulness of the test as a test.
0Bound_up
I'm not positive I understand. You think that letting Harry have his wand either is or isn't a sufficient clue to deduce that it is a test, and that If it is a sufficient clue, Harry will know it's a test. Harry's knowing it is a test will ruin the nature of the test. It if is not a sufficient clue, Harry cannot be tested by it, as nobody can be expected to deduce such a thing. Therefore, neither option aligns with Voldemort's goals, and the test is out of character for him as a rational being. If I do understand, I think the this part of my post implies the response I will now clarify: "But! For Harry to submit, and this of his own free will, this despite his apparent Plot-Induced Loophole, this is a proof of his self-mastery, and of his rationality. For to submit for lack of spirit is not the same as to submit for the understanding of its ideal nature." Allowing Harry to keep his wand is a sufficient clue that something is wrong. If it's enough to make me feel confused, it's enough for the more rational being Harry can become in this circumstance. Harry's deducing that it is a test does not destroy the test, because that is the test! ;) To deduce such a thing is a test of rationality. For him to be able to lose in such a situation is a further test of the great limit to his rationality throughout, his emotions, especially his pride, his disproportionate value of his own social dominance. So it was a feasible test of his rationality on two important levels.
[-]William_Quixote110

I think there may be some hindsight bias here. We know that Harry has partial transfiguration and we know that it turns out poorly for LV. LV himself did not know these things. To the best of his knowledge (which he has good reason to believe is considerable and maybe exhaustive) there is no magic Harry can cast wordlessly with his wand down.

For LV to enact the additional precautions above, magic would be needed. He can't use magic on Harry, so taking them means reducing the size of the death eater guard by 1 or more during the time needed to take those precautions. If you don't know that Harry can do previously unknown to the world wandless magic, than that might actualy not seem like a good trade off.

Additionally, regardless of if trading 1 guard for additional precautions is actualy a good security trade, it is totaly in character that the kind of mind that created horcrux number 107 after allready having over a hundred redundant horcruxes would think the additional redundancy of guard 36 over guard 35 to be valuable.

I take your general point, but part of Voldemort's character as we have seen it is that he is Crazy Prepared, building in failsafes and backup options and safety margins well beyond the reasonable minimum. He is not merely capable of dealing with whatever challenges the narrative throws at him; he is comfortable, even leisurely, in the manner in which he deals with them. I doubt the cost of temporarily reducing the Death Eater guard from 36 to 35 is greater than the benefit of a given precaution. I don't understand this sentence. Would you mind rephrasing?

You're right about the last sentence. Perils of typing on a cell phone. I've edited it to make sense.

Fair enough. In regard to that, I would also observe that Voldemort (likely correctly) thinks his Death Eaters are idiots, which mitigates their perceived value to him versus precautions he personally would think up.

But Voldemort does know that Harry can cast one particular type of wordless, wandless magic -- he knows it because he taught him. Harry can end transfigurations. And he still has his glasses. Can Voldemort sense transfigurations that Harry is maintaining? If not, Harry could have a piece of Scotch tape stuck someplace it wouldn't be noticed, or a booger hidden up his nose, or a capsule up his butt like a drug smuggler, or a tooth, or a fingernail, or a toenail, or... If Voldemort can't sense Harry's transfigurations, he should be operating under the assumption that Harry has a capsule up his butt that he can excrete and untransfigure into a deus ex machina. He doesn't need his hands to end a transfiguration, and he doesn't need his hands to poop. (If you prefer it to be a tooth, say it's a tooth. That's what Voldemort did.) Of course, Voldemort doesn't seem to be the sort of person who would do that. He goes through the motions of being careful, but constant vigilance is not one of his strong points. And that's not, narratively speaking, a character flaw: if you think everyone else is a stupid NPC, you're not going to see a point in paranoia. He should've kicked himself in the face as soon as he taught Harry how to do that. But he's not the sort of person who would. Also, Harry should start carrying some transfigured teeth. A gun, a knife, and a broomstick, maybe? But I think I'm not being paranoid enough.
0TobyBartels
Only 3 transfigured teeth? Not paranoid enough! He's got room in his mouth for 28 items. (Or 32 if he has a big mouth.)

I'm with everyone else on the wand thing. It would have been simple enough to have him drop it. One narrative explanation for getting the wand back into Harry's hand would have been V asking for a demonstration of PT after Harry told him of it. Another would be to throw away the simplest timeline thing and let time-turned Harry come to the rescue with that solution, wand, cloak, etc. in hand. Though I don't know why V left him an hour on the time-turner either. But: My real confusion starts way before all of this. You have the idiot-child of prophesied destruction, and what you do not do is back him into a corner where he may decide to do something desperate. Making Harry feel threatened was a big risk to take with that prophecy. V transforms into a super scary villain, putting Harry under massive duress, the exact kind of thing that would possibly cause him to destroy the world through time paradox or some other unknown power. It would have made more sense to bind him with an unbreakable vow long before then, to maintain the pretense of friendship throughout. So he guessed you're Voldemort, fine. Come clean, acknowledge what your plan to rule Britain was, and that you have been planning to place Harry as the ruler this time. Have that discussion. Come clean about the existence of a prophecy. Tell him you intend to resurrect Hermione. That you need to know what secret power he has so you can help him avoid the inadvertent destruction of the entire universe. Remind him of the centaur prophecy. Get him on your side that he is a serious risk to everyone. Brief the Death Eaters ahead of time, have a few that Harry doesn't know present out of uniform for a fake ritual of divination that supposedly requires him to be completely nude and holding no objects. At the agreed upon time in the ritual they all just AK him and Harry dies with his eyes wide going "Wait, WHAT?" and thinking you were his friend until the last. V broadcasts his betrayal so far in advance, and that

Definitely worth saying. I know I'm being very critical in this thread, but that's largely because I'm so emotionally invested in this story, which in turn is because it's an extraordinarily good story.

I missed when writing this that there was the curse preventing V from killing H. But he still could have just let the centaur kill him. If the curse also stopped him from allowing the death of H then he still could have tried to get the Unbreakable Vow from Harry before making shit hit the fan.

He made a point to have Hermione alive in case Harry get out of the situation. It's no mistake that he doesn't.
2Eliezer Yudkowsky
Hmm... the blinding one is potentially interesting, if Harry partially-Transfigures himself eyeballs using the fact that his hand is touching the wand, and uses the Stone to make them permanent later... but he'd have to avoid Voldemort noticing that his eyes were back.

So he regains his eyesight and then notices that there's a black-painted bubble-head charm on him, just in case. x) Voldie really should have gotten Moody as an advisor.

I feel I should reiterate that I agree with you. I'm not seeing an in-universe reason for Voldemort's behavior in these two chapters either, except for maybe "He was overconfident and didn't see the need to take such excessive precautions", which isn't all that narratively satisfying, though it is somewhat realistic. (The planning fallacy is a thing, after all, and even Tom Riddle Jr. Sr. isn't immune.)
0ChristianKl
I don't think there a good reason for Voldemort to think that giving Harry another minute with his wand adds much on top of what Harry could already do before.
1Velorien
Look at it from another perspective: Voldemort's actions are based on the belief that Harry has powerful secrets unknown to him. One or more of those secrets may well lead to the end of the world if Harry lives. Given that Voldemort is acknowledging his ignorance of Harry's full capabilities, is there any possible excuse for not trying to limit those capabilities as much as possible?
0kilobug
Half of those would either have prevented Harry for reveling his secrets to LV (paralyze, Imperius) or not changed anything in that case (bind with a rope, remove glasses, horcrux, hostages). Some are doubtful : confudus I'm not sure it would have worked since Harry is an Occlumens, illusions to hide a few Death Eaters, I'm not sure the remaining hidden Death Eaters would have done anything when seeing all Death Eaters dropping dead and LV collapsing. Death Eaters aren't especially loyal nor courageous, they obey by fear, and a 11 years old boy able to kill a dozen without moving (and who is known to scare dementors, and ...) is as scary as Voldemort. Now, sure, it's always possible to imagine in hindsight ways Voldemort could have used to save the day for himself. As it is for Dumbledore before, and for Harry earlier (see the lack of recognition code, ...). But if you nitpick that way, is there any fiction that is satisfying for you ? People do mistakes, even very smart people. The only real mistake Voldemort did was the wand thing, the rest is pretty much nitpicking. And one mistake, which with Voldemort knowledge was very low-risk, can happen without hurting too much the suspension of disbelief.
7Velorien
It doesn't matter so much that Voldemort didn't see the exact means of his downfall coming. What bothers me most is that he was sloppy. The point of my post is that I am much less intelligent than Voldemort, and vastly less experienced in cunning and subterfuge, yet I was able to think of a dozen relatively practical means of reducing risk from Harry in 20 minutes. How many would Voldemort have thought of and implemented if he'd tried? Maybe they wouldn't have worked against the actual solution Harry chose. That only makes the story better. It means Harry successfully defeats the Voldemort we know and love, Voldemort at the top of his game, not a cut-down Voldemort shacked by a sudden Idiot Ball. A satisfying way to defeat Voldemort would take advantage of his genuine weaknesses - his despair in humanity, his loneliness, his arrogance, his inability to comprehend genuine compassion, his need for a worthy foe. But until the latest chapters, he had not been shown to have the weaknesses of carelessness, poor planning, or leaving a dangerous enemy armed when they are in his power.
3hairyfigment
Why assume you're "much less intelligent than Voldemort," in addition to the gap in experience? As others have noted, he makes mistakes all the time. (I was surprised by the news that he actually died and was actually trapped for years, but not by him leaving Harry's wand alone given this previous information.) We know that V had vast experience with magic and secret information about the same, which could support your view but could also be a disadvantage when it came to partial transfiguration. Note that the mistake he knew about with the Horcrux network (and would perhaps have updated on) partly consisted of thinking he could overcome a long-established magical limitation without testing it. Maybe the actual complaint should be that Harry's use of partial transfiguration shouldn't have worked without more testing - though here we know that he based it on vast civilizational knowledge which V had only begun to assimilate.
3Vaniver
So, up until the prophecy, Voldemort can coexist with Harry. (The reverse may not be true.) So why did Eliezer add the prophecy to the mix? Was it just to set up the eventual duel between H and V? It seems to me that that's the place to do an Author's Saving Throw, if there is one; if people reason about V as an optimization process rather than a character, they will never be satisfied by V losing a duel because V is defined by his duel-winning property. So the only winning move is not to play, but there are satisfying ways for that to happen. (In fact, I think I might write that up in long form.)

Yeah, this is one of those solutions that, had I been writing, I would have ruled as not actually workable. Takes too long, Voldemort or a Death Eater sees the threads and breaks them on general principles, nanotubes don't actually have enough tensile strength to reasonably slice up everybody at once consistently, and so forth. I pretty much filed any tactical violence plan under "not practical".

Still, not my story. It's not out of keeping with the rest of the stuff in HPMOR.

High odds that Voldemort escaped. He's been extraordinarily hammy this whole time, and he called all the Death Eaters together, killed or crippled a few, and then explained his evil scheme to the hero before giving him a countdown to his inevitable death, while leaving him armed. It seems very plausible that Tom Riddle was tired of Lord Voldemort, and decided to retire him via dramatic massacre. Why make his new body a snaky freak-show, after all?

On the pedantic nitpicker trivia side of things, you don't have a tank of "oxyacetelene". An oxy-acetylene rig uses a tank of oxygen, and a tank of acetylene. But Harry is probably not a welder, and neither are the Weasely twins, so nobody involved was equipped to notice the problem.

8Transfuturist
The volume of the transfiguration makes it negligibly quick; nanotubes have the highest tensile strength of any material and they were not lone tubes, but braided; I'm fairly sure spotting a braided nanowire in the dark is nearly impossible; and the tension transfiguration is what made the slicing consistent. How exactly is it not practical?
3DanielLC
That's why you have multiple tactical violence plans running at the same time. Mine had neurotoxin and jets of fluorine. Also, Harry could transfigure a flashbang if he gets noticed, and he reinforces his body with carbon nanotubes for in case he gets shot.
2Subbak
We know for a fact that the Hogwarts wards do not raise an alarm when they should, because they did not detect Draco being under a Blood-Cooling Charm. And we also know that Voldie had a better idea regarding those wards (whether he actually had said wards in place around Draco is debatable, but still, he had the idea). So I think it's extremely probable that the wards he has to detect his own death are more efficient than the Hogwarts wards, and he's currently riding Bella's body and kicking himself for once more not having just used Avada Kedavra.

Or he and Bella are kicking back on a beach in the Caribbean, drinking alcohol from coconuts and murdering anyone who plays loud music nearby or fails to clean up after their dogs. Rematch in twenty years.

The Blood-Cooling Charm was invented for the story specifically to offer a means of murder that didn't set off the wards until the point of death; furthermore, if a professor (Quirrell) cast it, the wards wouldn't trigger anyway.
4Subbak
Well, yes, but it had to be believable that Hermione had cast it, therefore we can assume that it would not have triggered the wards even if Quirrel had not cast it.
[-]Nornagest170

Me too. I didn't say this a couple of days ago, owing to a lack of confidence that I now see to have been misguided; but while the nanowire PT solution is reasonable and effective and exactly the sort of thing that a sci-fi fan who fancies themselves clever would come up with, it's narratively shallow. And I can't see messily killing thirty-six people as in character for Harry at this moment, however much noise has been made about killing intent. Coming up with creative ways to kill people is one thing; actually going through with it in anger, or even thinking of it when faced with real hostility, is quite another.

(I'm also not totally sure it would work, but that depends on messy materials-science math that I can't be bothered with right now.)

Lest I be accused of being overly negative, though, the Obliviation bit does have a certain elegant symmetry to it.

Convenient, is it not, that Harry had the apparent necessity of killing all the Death Eaters? Good guys only kill when they have to - but somehow, after the heros have nobly declined to kill the bad guys when they aren't forced to, the cops always manage to get their guns stolen by the criminal, and the good guys get to take them down in self defense anyway.
2gattsuru
MoR!Harry's opposition to killing has always been more of a philosophical objection than an instinctual one, foreshadowed heavily back in chapters 7, 10, and 16. Given the effects of Voldemort's alterations to his brain during youth, depending on your idea of identity this not the typical situation of confronting the psychological cost of taking life. Ironically, non-lethal transfiguration was probably available, even if Harry wouldn't or couldn't think of it -- there's no restriction to, say, converting people's blood into propofol or methohexital, for example. That'd be unhealthy even beyond the normal health risks of human transfiguration, but in exchange for its risk of breathing issues and transmutation-related blood-clot-in-brain effects, comes with the benefit of exceptionally fast activity, and the volume required is well within the constraints of the problem. While the Deatheaters are more complicated a problem despite Voldemort calling them useless, there are a handful of other possible solutions that would be less likely immediately lethal. The only person Harry /had/ to maim was Voldemort, and that's because direct transfiguration would have alerted him. Given that Harry almost certainly killed Sirius, and probably killed Lucius, and we have a number of chapters left, this may well end up being a narrative complication and a flaw, even if an understandable one.
1buybuydandavis
Free transfiguration requires wand contact with the object, right? Seems a little arbitrary at the quantum level, but I think that prevents Harry from just transfiguring someone's blood from afar.
2gattsuru
It's implied that more experienced wizards and witches can freely transfigure objects at a range, but Harry can't do that. However, even without Partial Transfiguration, objects that have been joined together can be transmuted as a whole (see chapter 28, with a wand touching one part of an object and converting parts into different components. We've also seen transfiguration operate differently on different components of a system. Once Harry has stuck spider-silk between his wand and a Death Eater, he can convert components of the Death Eater as easily as if he were standing next to them. Harry's not shown any interest in this sort of biochemistry (the closest we've seen is a reference to "knockout gas", which means he knows less than nothing), and while propofol was well-known in 1992, it's not referenced in the sort of literature he's likely to read, he has been trained not to consider transmuting humans, his character isn't really aligned with less-lethal conversions, and there is a very high complexity penalty to this plan. There are also some possible volumetric issues. We hadn't gotten an actual transfiguration rate since chapter 23, where he could only do five cubic centimeters per minute, while it would take about ~15 cubic centimeters of propofol to rapidly sedate this number of Death Eaters. The post-exam chapter gave an update of cubic millimeter "as fast as he can concentrate his will and magic" and "in a fraction of a second", which is imprecise enough to be useless. He was able to transfigure a unicorn in about an hour and a twelve-year-old's corpse fast enough to avoid notice, recently, and presuming unicorns are similar in volume to even a small horse he'd need to be moving much faster than 15 cubic centimeters a minute (900 cubic centimeters is less than a liter, a very small shetland pony would operate somewhere in the area of 180-200 liters, so... not sure folk did the math on that one). But it's interesting as a thought experiment. This isn't

Voldemort doesn't want the world destroyed, and he just made Harry into a world-destruction-preventer. Pointing this out — and pointing out that Harry is now a better world-destruction-preventer than Voldemort could become — doesn't involve changing Voldemort's utility function.

(Voldemort can't swear an Unbreakable Vow akin to Harry's because nobody has trust in him that could be sacrificed to power it.)

He didn't make Harry into a world-destruction-preventer. He only made Harry swear not to actively destroy the world.

He doesn't have to be persuaded to be good, he just has to be persuaded to let Harry out of the box. If he lets Harry out of the box for non-good reasons, that still counts.

The rules stated that we couldn't change Voldemort's utility function or turn him good, but his utility function already placed an extremely high value on not having the world destroyed, or losing his immortality. It was quite possible that the solution would have been to convince him that killing Harry would end the world, or that he required Harry in the future in order to save it. The Vow and the parseltongue both were valuable tools in convincing Voldemort of this.

I feel like the problem turned out to be unnecessarily easier than it had to, that too much of the credit is due to luck, and some things could've been done better (Death Eaters could be saved). It's somewhat of a theme with all these spells and rituals being performed in unique situations and working on the first try, with little precaution taken to test them or theoretical grounds to expect reliability. For example, Hermione still wasn't tested. It's the first resurrection ever performed, at least by the people present. It involved further effects that might've never been combined in this way before. The person who knows the details is now defunct. He didn't plan to test it either, for the primary use case intended. Hermione's brain is warm and might be losing information or she might get terminally sick soon, with brain damage. We just assume everything worked.

One problem is that Harry didn't know that he can remain conscious after directly casting a spell at Voldemort, so it should've been planned around, with the less direct transfiguration being plan A for rendering Voldemort unconscious. We now know that this might've failed (more likely than before Ch. 114), and there had t... (read more)

To clarify, Harry at one point was given a list of wards an inner-circle Death Eater would be expected to have prepared, which include anti-time-turning. We don't see Voldemort or anyone else cast such wards, so it's down to whether we think Voldemort has permanent versions around his sanctum.

My criteria for whether a character acts smart or stupid is whether I can see a glaring issue immediately. Like many others, I had asked right after ch.113 "why does Harry still have his wand and his glasses"? And, sure enough.

Dumbledore appeared much more wielding the "idiot ball" than Voldemort in this final arc. Voldemort initially needed Harry to have his wand for the Unbreakable Vow. Yes, it was a mistake to not remove the wand from him afterward. He couldn't imagine Harry would be a threat with a wand without being allowed to speak or move it, partial transfiguration of carbon nanotubes or antimatter from the wand itself just was unimaginable to him, so it's an understandable mistake, but it does strike as odd when compared to all the precaution he's taking in "paranoia mode".

Wow, I was expecting more of a pure Talking His Way Out of the Box solution, instead of a partial transfiguration solution. I'm curious as to whether or not this is the bad ending. I do think Voldemort was a bit stupid to not just kill Harry instantly instead of quizzing him for the Powers He Knows Not. As he said himself, given an eternity of immortality it is likely he would stumble across everything Harry has read, thought, and figured out.

A lot of people think that Voldemort was going too easy on Harry, making this a "Coil vs. Taylor in the burning building" violation of suspension-of-disbelief for some of them. I am considering rewriting 113 with the following changes:

  • Most Death Eaters are watching the surrounding area, not Harry; Voldemort's primary hypothesis for how Time might thwart him involves outside interference.
  • Voldemort tells Harry to point his wand outward and downward at the ground, then has a Death Eater paralyze Harry (except heart/lungs/mouth/eyes) in that position before the unbreakable Vow. This would also require a retroedit to 15 or 28 to make it clear that Transfiguration does not require an exact finger position on the wand.

I would add a reason for Harry to have the wand.

The big problem is that he left Harry his wand. If he uses more precautions against Harry, but still keeps leaving Harry his wand, then that makes the fact that he left Harry his wand less realistic, not more. So I actually think that you should go the other way with it - have him be less paranoid about Harry. Because otherwise you're making the inconsistency even worse. He's being cautious and paranoid enough to strip Harry's clothes from him, but leaves the wand in Harry's hand for one moment longer than he has to? It makes more sense if he has the Death Eaters throw a bunch of Finites at him to check for residual traps left by Dumbledore, and for that to be where he sees most of the threat coming from.

This. Voldemort's not only being paranoid enough to strip Harry's clothes from him, he's being careful and cautious enough to remove an object Harry Transfigured without letting their magics interact. That kind of attitude is jarringly inconsistent with leaving Harry his wand for no apparent reason. Luke_A_Somers already suggested adding a reason for Harry to have his wand. I think that adding such a reason combined with changes that increase our estimate of Voldemort's estimate of P(Time will try to thwart Voldemort's attempt to avert the prophecy through something other than Harry | Time will try to thwart Voldemort's attempt to avert the prophecy) would make things seem much more consistent; leaving Harry his clothes and having some (not necessarily most) of the Death Eaters looking outwards would both help with the latter. The reason I suggest increasing readers' estimates of Voldemort's estimate of P(Time will try to thwart Voldemort's attempt to avert the prophecy through something other than Harry | Time will try to thwart Voldemort's attempt to avert the prophecy) rather than just making Voldemort less paranoid overall in this situation is to avoid worsening the Villain Ball complaints; shifting his paranoia partly elsewhere allows him to be the sharp antagonist we're expecting while suggesting that he's confident the precautions he takes are sufficient to neutralize Harry as a threat (which allows Harry to win). That confidence isn't out of place for his character - even though he's read Muggle books, it's entirely plausible that he hasn't integrated that knowledge well enough to start questioning what he knows as the limits of magic (and thereby come to think of partial Transfiguration, or more generally realize that Harry might question those limits and succeed in discovering something he can wordlessly cast without pointing his wand). The particular changes I mentioned also have the side benefit of not really affecting the major proposed solutions to

Having the Death Eaters look around makes sense, but the paralysis seems contrived to me. It's a very specific level of intelligence between what he have now and just having Mr. Grim cast Expelliarmus.

As AlexanderWales says, the biggest flaw is the wand. If you add a line about harry being left holding his wand so that Voldemort can impose further unbreakable vows if he sees fit, or he has it left in case he needs to demonstrate any secret knowledge (along the lines of Patronus 2.0), Voldemort goes from holding the Idiot Ball to just making a mistake. He's trading off Harry possibly doing something impossible with his wand vs a far likelier benefit.

The biggest problem for me is that when I imagine myself reading these events and Voldemort going, "A nice try but I can sense whatever transfiguration trick it is that you're using. Thank you, that will take me some time to perfect in my eternity," I don't feel surprised. Throwing additional stipulations and conditions into the situation doesn't change the fact that the way in which Voldemort loses is not convincing. It doesn't feel like Harry earned the win because I can just as easily imagine Voldemort laughing at Harry's childish tricks and killing him. For the finale to truly be satisfying, there has to be a specific, pre-established reason why Voldemort was unable to defend against Harry's tactics and, at least in my mind, this was not the case. Simply being unaware of partial transfiguration doesn't cut it. This is a person who casts nearly thirty charms to discuss sensitive information in Mary's room and recognizes the value of ambush and surprise attacks. Yet in his final moment of securing his eternity is unable to sense transfigured material winding its way around himself and his followers. Material transfigured by person he has a known magical resonance with. It simply does not feel reasonable for Voldemort to lose like this, no matter how many addendums are added to justify his behavior in these final chapters.

I do remark that Dumbledore was unable to detect Harry doing an ongoing Transfiguration while he looked into Harry's prison cell in Azkaban.

I admit I did forget about that specific incident. However, Dumbledore going cell to cell in Azkaban and Lord Voldemort attempting to subvert a prophecy predicting the end of the world in a fixed, controlled location seem like two very different things from a reader perspective. It is also implied that Dumbledore did sense Harry's magic - at least on some level. But he dismisses this because he is looking for a wizard strong enough to break into Azkaban and free Bellatrix Black. Lord Voldemort on the other hand, should be immediately and unconditionally suspicious of any and all magic he senses from Harry Potter.
5TobyBartels
That's Dumbledore reading Harry's mana level, not sensing whether Harry is casting spells.
0hairyfigment
An excellent point. I was going to say that Dumbledore was also unable to detect Harry's horror at Hermione's injuries "through the link that existed between the two of them, the resonance in their magic," nor did he feel "the boy exterminate his enemy in seconds." But on inspection this doesn't actually say he could feel the spells Harry was using. And Harry's scar does not appear to react to e.g the repair of Hermione's body or the summons for the Death Eaters. The doom-sense could have a lot to do with both the strength of the magic and the degree to which it inherently clashes with the senser's inclinations or goals.
0Sheaman3773
To me, it seemed that it scaled with their current mindsets and actions, with stronger being the more they contrasted. Consider how strongly it was felt when Harry's "anti-death-ness" was particularly strong (e.g. after Harry killed his first Dementor) or when Voldemort's desecration of death was higher than normal (e.g. when he makes Inferi). Inversely, look at weak the feeling is when their current mindsets are not so opposed (e.g. when Quirrell was in zombie-mode in ch 49, because he practically lacked a mind at those times). Though, the zombie-mode in ch 26 was still fairly strong, which could imply that zombie-mode isn't as big of a determinant as I initially suspected. It might well be another piece of evidence towards the importance mindset, however, as that ride ends with Quirrell leaving to "set something into motion," which is certainly ominous coming from Lord Voldemort and may well have been something Harry was inherently set against. I don't remember if we found/figured out what he was doing there. Taking this into account, the lack of doom-sense during the transfiguration would simply be there not being much of a mindset left. Though I fear I may have strayed from the original thrust of your post.

I think the only thing that would satisfy me is a legitimate excuse for Voldemort to leave Harry armed. Anything short of that, you may as well leave it as-is for historical reasons.
8Vaniver
I'm going to repost something I wrote in another bit of the discussion: V has established that he is willing to try to intervene at every possible point when it comes to breaking the prophecy. So he would paralyze Harry, and take Harry's wand from him, and destroy Harry's wand. Especially in the context of V asking Harry to share secrets V doesn't have. It seems to me the simplest place to intervene is the characterization of V. Have Harry, during one of his bleak "how the heck am I going to defeat V" moments (or possibly at the start of 114), remember what gattsuru talks about here. V is sharp but limited; Harry can use those limits against him. Then Harry surprising V makes more sense, and every idea Harry uses could explicitly be linked to one of V's weaknesses. (For example, Stuporfy works because V disdains dueling.) Even then, I do not think it will work fully, and some readers will only be satisfied by a 'mutual victory' ending. I have in mind an ending that would work for that that I'll write up when I have time for fiction (tonight?), but it requires more changes earlier and may not match at all your goals for the fic. (Incidentally, if I were in V's position and knew about Time-Turners, those could be used to add a further layer of security. I would precommit to Time-Turning back an hour and asking Harry to reveal his secrets in the presence of my original version iff Harry in fact revealed his secrets to the future copy of me that appeared and then died quietly; otherwise I would kill him immediately. This might violate the "use Time-Turners for arbitrary computation" rule, but I don't think so; it seems closer to asking Flitwick to rescue past-you, or the original Time-Turner prank, or a minor modification of it could move it into that class.)
0Vaniver
I realized this morning that I should be clearer: obviously, V knows that Time-Turners exist. But does he know enough about their function to know exactly how the information-backpropagation prevention works, and which loops you can reliably create, and which ones you can't? That seems like the sort of thing that would require extensive experimentation that he may or may not have done.
0buybuydandavis
And intervening with the prophecy is about removing Harry as a threat. He only let Harry speak because he wanted his secrets. Got greedy and overconfident. Fine. But I see no reason Harry needs to have his wand to have that chat. Paralyzing him would be another precaution, but that would be secondary to taking his wand - without his wand, he's a very smart little boy. If an edit could be found to justify letting Harry keep his wand, I think that would do it for me. Hmmmm. On EY's new scenario, would magical paralysis automatically wear off if the person who cast the spell dies? Does Voldemort need his wand to leave his body? Seems a pretty hard row to hoe for even just a paralyzed Harry, to keep Voldemort from leaving his body or otherwise escaping.
7dxu
What I'm uncertain about is what was going through Voldemort's mind at the time. I have no idea what he was thinking when he let Harry keep his wand, and so for me, that part kind of fell flat, especially when it turned out there was no explanation other than, "He was overconfident"... which sounds like an explanation, but isn't one, not really. It's just like saying "magic" or "phlogiston". How does the mokeskin pouch work? "Magic!" What causes fire? "Phlogiston!" Why did Voldemort let Harry keep his wand? "Overconfidence!" For me, that just isn't specific enough of an explanation to actually allow me to make predictions. My model of Voldemort can't receive "overconfidence" as an argument and spit out the action "let Harry keep his wand"; the argument isn't well-specified enough. How was he overconfident? What was his exact train of thought? As Harry put it in 108: Since the explanation "overconfidence" didn't make me feel like I would have predicted Voldemort's actions in advance, it remained an improbability. I'm not suggesting for you to add a scene from Voldemort's point of view into Chapter 113 or something--that would be a jarring shift in perspective, IMO. (Although it would be nice if you could somehow give a hint at Voldemort's motives--I particularly liked Luke_A_Somers' suggestion.) That being said, I am curious: what was your model of Voldemort thinking when you had him let Harry keep his wand? If not too inconvenient, could you elaborate on what you were modeling Voldemort's thoughts as?
6Duncan
If you want to make the scenario more realistic then put more time pressure on Voldemort or put him under more cognitive stress some other way. The hardest part for Voldemort is solving this problem in a short time span and NOT coming up with a solution that foils Harry. The reason experienced soldiers/gamers with little to no intelligence still win against highly intelligent combatants with no experience is that TIME matters when you're limited to a single human's processing power. In virtually every combat situation one is forced to make decisions faster than one can search the solution space. Only experience compensates for this deficit to any measurable degree. In this situation there are several aspects that Voldemort does not have experience with. If he must spends his cognitive resources considering these aspects and cannot draw from experience it makes mistakes much more likely.
5Tenoke
I'd like that slightly more, but such minor changes barely address the issue. Also, I am already suspecting that the way in which Harry will unparalyze himself after his improbable PT rampage is just going to involve some other unlikely feet.
2MarkusRamikin
I voted for the change, but I don't feel these are crucial changes... I think a clearer problem is that it is not obvious, until Harry actually does it, that he could cast Transfiguration on his own wand. Or cast spells on his wand in general, it's a bit like a gun shooting at itself. I say more on this and propose an easy solution here. Chances are you've seen it and didn't agree, but saying just in case.
2[anonymous]
I would've had him transfigure a sliver of one of his fingernails, unless it has to be touching the tip of the wand.
2MarkusRamikin
Yeah, that would work too, as long as it had been established earlier in the story that it doesn't have to be the tip.
2polymathwannabe
Please don't change it. It's more than awesome enough as it is. Even if I did expect partial transfiguration to have some role, using the wand itself as raw material was tremendously surprising. For many people it will look too easy, but only with the benefit of hindsight. Edited to add: some previous chapter should be modified to establish that transfiguration is indeed wordless. Edited to add: I'm stupid. Chapter 15 says it is.
1Tenoke
Only with the benefit of hindsight? I bet 3 people that the solution won't involve PT, 2 of them within hour(s) of chapter 113 coming out, as it was the most obvious (while impausible for some) solution for many people. Specifically transfiguring the tip of wand/leg/earth/air into nanowires was mentioned by so many people within minutes of posting the chapter.. There was no hindsight involved.

The solution was actually posted to reddit after chapter 112, before there was a final exam at all.

The climax and the reader reaction to it have been slightly better than I was expecting. I would certainly not complain about improvements, but there are probably better marginal returns elsewhere.
0ArisKatsaris
Instead of "having a Death Eater paralyze Harry", I suggest that Voldemort paralyzes Harry himself before the Death Eaters arrive by throwing a trapped Knut at him with Petrificus Totalis set on it to trigger or something. Then Voldemort, just before the Vow, asks one of the Death Eaters to partially remove the paralysis just from Harry's head. This looks all the way simpler. A paralysis is good from Voldemort's perspective, but if it is good to have it would be good to have from the start -- so as to be in better control of the situation rather than depend solely on the abilities of the Death Eaters -- and don't tell me that Voldemort couldn't have found indirect ways to inflict a variety of magical effect on Harry the moment he realized his magic couldn't touch him directly. EDIT TO ADD: Ugh, no, that solution I just suggested (trapped Knut with paralysis spell) has the problem of leaving Harry paralyzed afterwards, while the paralysis spell would be dissolved at the Death Eater's death...
0ChristianKl
Experimenting with different ways to use magic indirectly carries a risk, that it's not indirect enough for the effect to trigger. Voldemort might not want to take that risk.

My main problem with this whole thing is that LV doesn't get the death eaters to cast shields, most notably shields against material objects, which we know are a thing from the mirror saga. Obviously the resonance is a concern, hence the death eaters cast the shields, but there is no way that LV doesn't think that Harry is going to try something, he takes practically no precautions at all.

Harry can control the order of a transfiguration process, as seen in ch.104. Those are not threads floating freely in the air, they're part of a specific wire shape in the process of being transfigured. We also know that you can transfigure against tension.

Huh. Good answer. Totally forgot that, and I don't think I'm rare about this. I wonder if there might have been a way to make that more memorable.

Raise shields on general principles!

Presumably shields let air through, so they probably also let nanotubes through.

Well, I don't know how shields work in this setting, but one possibility is that shields do not let anything magical through, which would stop transfigured materials. Shields do stop bullets, so... is it a matter of speed? Do shields stop fast things like bullets, but let slow things such as knives through? If carbon nanotubes work, then wizards who are not familer with the latest muggle science could still stab each other with very thin (to the point of near invisibility) diamond blades.

Nit: Harry correctly guessing before this chapter that the resonance affects mainly the caster in proportion to the caster's strength seems overly specific. His experience did indicate that the resonance was a greater threat to V than to himself, so his actions were justified, but his prediction should have been more disjunctive: Either the resonance mainly affects the caster in proportion to the caster's strength, or it affects both parties in proportion to their strength, or it mainly affects V regardless of who casts what due to some asymmetry, or it affects the caster in proportion to the spell's magical strength, or something else.

So, what's the probability that Harry returns to the Quidditch stands, checks his watch, and then snaps his fingers right before the explosion goes off?

Cute, but it falls prey to the Wizengamot Mistake: the point of not leaving clues is not that the median person will understand the clue, but that any person might understand the clue.

I wonder if it would be possible to erase most of Voldemort, but keep the Quirrel mask personality through some combination of Memory Charms, Obliviation and Legilimency. He was a pretty cool teacher, after all, when not murdering the students and whatnot. Using the Stone, it would be even possible to give him a permanently-transfugured Quirrel body, so that the students don't get scared of Voldie teaching them...

I feel stupid. Not for the nanowire, as I was among many who suggested something similar.

I feel stupid for not suggesting the "make Voldemort insane" strategy. I thought it will not work because a wizard's mental state is not necessarily connected to his brain. For example, an animagus transformed into a cat can still retain her human mental state with a cat's brain.

But being driven insane because of a curse might be completely different, and could have an effect not only on the physical brain, but on whatever shape or form the mental state of a wizard is implemented in.

I believe the resonance from transfiguration is shown to be very minor, for whatever reason. When Harry has to transfigure Voldemort himself, not just contact him with transfigured material, it is only mildly uncomfortable. It is not incomprehensible that a much, much lesser contact could escape any notice at all until at very close range.
2hairyfigment
The resonance appears much stronger when he Obliviates the Dark Lord Tom than later during the Transfiguration. Of course the former could just be stronger magic, but I assumed the alteration to V had reduced it (and thus he couldn't have started with the Transfiguration in the hope of getting a more experience entity to do the mind-alteration later). This would support the theory that V updated his old Horcruxes somehow, or just didn't connect them to the network. (There could still be variant Tom Riddles coming some years later!)

Without any hesitation despite his wounds the Dark Lord jerked down and right through the air.

Something that could indicate trying to dodge, or consciousness leaving the body. It's not unreasonable for Voldie to think "I've lost here, no matter what I do this body will be unusable in the near future, in case he has a plan to incapacitate me without triggering my Horcrux wards I'd better go someplace else".

All in all I'd assign a high subjective probability to Voldie's spirit being intact. Voldemort is a thorough planner, so total Oblivation is... (read more)

Let's suppose for a moment that Voldemort realises in time that he's about to be got rid of in some way he'd not predicted and loses his body before Stuporfy hits him. Are there still any justifiable ways for Harry to win [i.e. incapacitate V at least as much as in 115 by all justifiable means]? He would probably have to get back in time as fast as he can, before he witnesses death and/or torture of his parents/friends (which V is going to start), so he can create a time loop where they are safe. But what to do next? Harry has an hour to protect a lot of people he cares about from a bodyless spirit. It won't do to gather them all in a safe place only to have V enter one of them and kill the others. It's going to be harder to devise a plausible mistake for V because now some of the plot devices planned from the beginning won't help us. ETA: I mean, Harry only needs to hit Voldemort with a spell strong enough to knock V out, but light enough not to knock Harry out and not to exhaust him. And V now knows that and may escape the body even if he can't evade the bolt. Unless there are extra-fast sniper magic wands, there needs to be a trick. As stated in 108, V is now free to select whom to possess from a lot of weak/willing people. I wonder if Hermione can be possessed at this point: is she sufficiently weak? (no idea) does possession mean harm? (probably yes, because the body of Quirrell aged too fast) does V's promise not to hurt Hermione still stand? (maybe yes, but if not, V now has a very young and durable body to live in)

I am starting to think that Lord Voldemort planned to commit suicide by proxy.

And now we really know why Harry had to carry around his father's rock. For practice:

And meanwhile, just like magic hadn't defined a Transfigured unicorn as dead for purposes of setting off wards, Voldemort's horcruxes wouldn't define a Transfigured Voldemort as dead and try to bring him back.

That was the hope, anyway.

Well done Eliezer!

I have read lots and lots of 'partial transfiguration' solutions over the past few days. I didn't really like them, they seemed artificial, unrealistic.

But somehow when you told the solution, it didn't feel artificial at all. It felt like it made sense. And I really liked the way Harry stalled for time as well. A few very nice tricks there.

I'm not sure why Harry went through all the trouble of covering up his involvement though. Is there a reason he doesn't want to to take the credit? Is he afraid it will give away the secret of partial transfiguration? Or perhaps he doesn't want Draco to know he, presumably, killed Lucius? I guess we'll find out tomorrow ;)

There are a lot of theories over at fanfiction.net that Harry is inside the Mirror, seeing what he wants to see.

I considered this possibility back when we were searching for Harry's solution, and found that Voldemort uses the same hand for wand and gun before and after the Mirror. I thought: If they are in the Mirror, Eliezer would have subtly indicated that, perhaps Voldemort's use of hands would be reversed since the Mirror.

Does this qualify as sufficient proof that Harry and Voldemort are not in the Mirror?

0Nornagest
It'd be a clever tell if Eliezer wanted us to conclude they're still in the Mirror, but I don't think its absence is strong evidence of the opposite. The Mirror might not work that way, and Eliezer might simply have forgotten if it did. (I would say it'd be clever if anyone walking into their dream-world died soon after of amino-acid chirality issues, but similar things have been done so many times that it's not very creative. Plus it clashes with the theme.)

Two things strike me as odd that I don't seem to have seen yet in other comments (but I might have missed them).

  1. How could the "torture" option work ? From my understanding, if Voldemort gains consciousness again, he can leave his body. And you can't torture someone who is unconscious. The wand in Azkaban pit could work, but the "call Moody to torture Voldemort" option I really don't see how it could work.

I've seen it suggested that V can leave a possessed body (becoming a disembodied spirit) but not his own. I don't recall seeing anything (either in canon or in HPMOR) that confirms or refutes that. I share your concerns about #2, although generally "once you have physical access to the hardware, it's over" -- if you can catch Voldemort or Dumbledore or whoever asleep, you can smash their head with a big rock or something.
0Velorien
I don't think we've seen any evidence of that in the story. For what purpose? If you've got your enemy at your mercy with their shields down, you either kill them, or you do something more useful with them (e.g. Imperius). I don't see what you'd get out of Obliviating them instead of either of those options.
1kilobug
Imperius isn't fail-safe, you can't Imperius strong-willed persons (at least not in cannon), I don't think you can Imperius Voldemort, Lucius Malfoy, Dumbledore, Moody, ... Even Harry can resist the Imperius in cannon. And while it's true for the "bad guys", AK is more efficient than Obliviate, for the "good guys" who have restraints in killing (like Dumbledore and at least half of the Order of the Phoenix) using Obliviate on death eaters would seem much better than killing them or sending them to Azkaban. I always assumed they didn't do it because it wasn't that easy (long/delicate casting, don't work on Occlumens, ...) to wipe memories massively like that.
4gjm
Lucius Malfoy claimed to be Imperiused during his time as a Death Eater. That claim needs to have been credible enough that his allies in the Wizengamot could use it to justify voting not to send him to Azkaban. That doesn't mean it has to be very credible, of course. But it had better not have been common knowledge that Imperius only works on weaklings.
1Luke_A_Somers
I think it was more that it works for nearly everyone, not only on weaklings.

On the other hand, the good guys are bound by the law, which dictates that surviving Death Eaters go to Azkaban, whether Dumbledore and co. want it or not.

So... Quirrel told McGonagal that he was David Munroe, and it was implied with Madam Bones. It looks like David Munroe was killed in a battle with Voldemort, ending that noble and most ancient line, which has now been avenged by Hermione destroying Voldemort with her magic Girl-Who-Lived powers.

Are we going to get the Noble House of Granger? Does the House of Potter lose its noble status since David Munroe was apparently not previously dead to be avenged by Harry? Will they both be noble because the Wizengamot doesn't know what to do with the ambiguity?

Voldemort still killed David Monroe, he just did it earlier than everyone thought he did. Chapter 108: Your other questions remain, though. Harry no longer killed Voldemort for good, and Hermione (apparently) has. This should be interesting.

Didn't he want to create a horcrux out of Harry, not to kill him? Of course, he could have implanted himself the false memories he shares in ch. 108: Or he might have lain, which means that either he did want to kill Harry, or the purpose of all that October 31st was something completely different. Or did I misunderstand something?

I know, right!? I feel this is a glorious moment. Reductionism, consistency, causation. These are hallmarks of rationality and of the Methods thereof. Anybody with sufficient understanding of the situation should be able to deduce the outcome, because it is dependably going to be whatever the rational answer is! Decision Theory allows us to identify the best course for a certain set of values and goals, and the rational answer will be the same for everyone. That this actually worked is a sign of the very tight internal consistency of the story. That this would almost never work in any other story is a powerful indicator of the opposite.

Nitpick: It doesn't matter how much or how little understanding; as long as you specify the knowledge available just as you specify the vallues/goals, then everybody still gets the same rational answer.

So did Harry just outsmart himself? Are we really expecting the clever Lord Voldemort to not have something in place to recover from obliviation? Harry seemed to appropriately judge the importance of this spell about half a second after he first heard of it, but Tom Riddle doesn't realise at all?

Reply
7Oshi
I'm sure he realizes it, but Harry literally obliviated everything in his memory, which would presumably include knowledge of any anti-obliviation counter measures (like the signals that were mentioned early on). Unless there's some spell or artifact we haven't heard of before now that blocks/reverses Obliviation, I am going with it worked. And from a meta perspective, we know the story is winding down, so Voldie coming back with his full memory and then having another showdown with a different solution seems highly unlikely.
[-]Bound_up100

There is an artifact that might suffice, the Pensieve. Voldemort might have prepared such an artifact with all his memories, and had Bellatrix and/or others ready to restore them to him by it if necessary.

But I grant the extreme difficulty Voldemort is likely to have having been transfigured into a ring. If necessary, Harry can always do with the ring what Voldemort did with the Horcruxes and ensure it is lost forever.

Possibly true; although I’m not sure whether Voldemort’s spirit would still stay inside the jewel once that transfiguration is made permanent. (Less of a problem now, thanks to the obliviation, but I’d still prefer some oversight, just to be safe.)

That might, however, make him no longer retain his original form, so then he's seriously dead, and the horcruxes activate.

Both good points. While Harry does actually have the means to overcome that difficulty, I admit I hadn't thought of it in the first place. Up-votes for both.

I agree with this interpretation. But given that, I'm not sure why Harry thinks he didn't kill Voldemort.

LV would anticipate this, so he should have something set up that will explain it all over to him again, automatically. Compare Fiona in Harry Potter and the Natural 20; LV could have done what she did, and she used no magic (and no Muggle technology more advanced than audiocassette recordings).
6roystgnr
The obliviated Fiona was still a policewoman who likes jogging with a walkman. The obliviated Voldemort isn't even still in the same category of "animal, vegetable, or mineral". The total obliviation is a second layer of precaution on top of that. At this point it's hard to even define "him". Even if some absent Death Eater's contingency orders just kicked in, and some magical trace on Voldemort defines where to deliver a post-obliviation message, that message is just going to end up in the hands of the obliviated ex-Tom-Riddle we like.
1TobyBartels
Being obliviated and transfigured is a pretty bad fix, yes. But they're both things that he could have anticipated. I don't know how to get out of that, but V might. Total obliviation requires more than just a message; it requires brainwashing to recreate the lost personality. Voldemort (I mean past V planning for these contingencies) can find a way. He just needs to shut up and do it! (^_^)

Um, that doesn't apply to anything Tom Riddle needed to learn from the basilisk. Which he actually did kill, to judge from the spiders (ha) and the lack of basilisk in the Tunnels of Secrets.

What about a Voldemort who comes back and just Avada Kedavras Harry on sight? This would finally do justice to Voldie's superior power and intelligence, and take only one paragraph. I was indeed thinking of spells or artefacts we don't know about (or perhaps clever combinations/side-effects of magic we do know about). If Horcruxes are indeed images of the caster impressed upon the world then perhaps it might be possible to construct them in such a way that they become active unless repressed by the original? That would solve Voldies stuck-in-a-plaque-for-decades problem as well.
0Oshi
Would you consider the story ending with Voldemort, up to that point presumed dealt with, suddenly showed up and killed Harry with no chance for recourse? It would be a quick resolution, but despite what Harry thinks as he matures, he is in fact living inside a narrative. I don't believe that the story would end on such a down note. I could well be wrong, but that is what I choose to believe.

I am glad to see that Stuporfy did the trick, and I did not see the Obliviate coming.

If I understand him correctly, H intends to keep V transformed until H is powerful enough to transform V’s body back to a healthy state (and make that permanent with the Stone). Imprisonment is a possibility after that, but depending on your views on the relation between identity and memories, this might not be appropriate after the obliviation.

So, it makes sense that if the thing falls, it could conceivably turn over and that activates the charm.

I really can't believe "use magic" was the right answer. In addition to being unsolvable from the perspective of the audience -- we don't know anything about magic! -- it's also totally out of step of the rest of the work. I'd love to see a rewrite fork from the "AI Box" line of solutions.

That's exactly what I mean. We don't know enough about magic to say what Harry or Voldemort's capabilities are -- the whole thing is a black box. It's not a satisfying answer to the puzzle (for me) and not much of a testimony to "rationality" as a way of thinking at all -- as presented this is about knowing genre conventions, not about superior or inferior thinking. All of the AI Box solutions I saw were much more pro-"rationality" by my lights.

One can network computers in such a way that computations, online services (web site), and/or stored information (databases, files) keep running seamlessly even after some nodes are crashed/destroyed/hacked.

Shouldn't a wizard's True Horcrux network similarly be resilient against any active body(ies) being Obliviated, Imperiussed, etc.?

Reply

That assumes a great deal of control over the design of the network. We don't know what steps Voldemort followed to design the Horcrux 2.0 ritual, but I don't think it implausible that the final result was the best he could do with the knowledge available, rather than the best an intelligent programmer could do with full control over the system's hardware and code.
1Jost
I agree. Also, the added complexity of distributed computations (Username’s suggestion) versus distributed real-time backups (the Horcrux 2.0) is enormous! Even for teams of extremely smart developers in 2015, distributed computing is not a simple problem. For one single “developer” in ~1990, like Voldemort (who has no like-minded individuals to discuss this with and has absolutely no background in computer science), this is near-impossible unless Magic has a built-in API that makes this extremely easy (which is unlikely, given what we know about the APIs for horcruxes, ghosts, etc.)
[-]drethelin30

I think the solution was over-constrained. Simultaneously killing 36 death eaters, disarming (hah) Voldemort, and then stunning him wasn't just A way out of the predicament without dying immediately, it's arguably the BEST way. All the limitations Voldemort put on Harry were irrelevant, and all the relevant ones that could've happened, like taking away his wand or shooting him in the kneecaps before he talks weren't taken. Voldemort forces Harry to use his ONE ability he can use without moving his wand, which also happens to be the one that can nearly effortlessly kill dozens of people in an instant? I guess when you look at it has him falling to the power he knew not it kind of works.

I don't think wizards can detect magic that easily. Patronus is definitely easy to detect, it radiates both in visible light and in... emotional waves, whatever that is ;) But think about how it's hard to detect someone who is polyjuiced, or someone who is imperiused. Or how Dumbledore had to cast spells to detect what transfigured objects did Harry has on him when he looked for Hermione body. It seems perfectly plausible that wizards can't detect (without actively casting some detection spells) a transfiguration that happens on the microscopic scale and can't see.

I woke up in the middle of the night with an idea that could still be true, but wasn't needed in Chapter 114-115. It had bothered me that the Hermione toe-ring wasn't detected. In fact, it was explicitly checked for magic and it was discovered that it was portkey magic rather than transfiguration magic.

Overnight, I had the idea that perhaps Harry put his portkey toering on Hermione's body (though obviously not her toe) before he transfigured her. I have no idea how such things work, but I suppose its possible that the portkey magic would still be detectible when transfigured and would even mask out the transfiguration magic.

From chapter 94 : I assume that he swapped the Hermione-toering with the portkey-toering at this point, leaving the Hermione-toering beneath the covers, or making it drop into the moleskin pouch, or something like that.

I remember that part too. I had thought that they had searched all of Harry's things. Upon re-reading the relevant part of Chapter 94, I now realise that they only searched his trunk and mokeskin pouch. If he left it in his bed it would have escaped detection.

I am somewhat surprised that no wards triggered on any of Harrys actions. OK, we learned little about what wards can and can't do but given that ant-apparition, anti-phoenix and whatnot are established by Death Eaters by default and Quirrell used - what 50? - protective measures in that secret hotel room when he left off for Azkaban.

Interesting. I wonder ifHarry just killed Sirius.

Dumbledore gave Harry a pack of cards that had portkey functionality, under the name Santa Claus and claiming that they were a portkey to Salem, but instead heading to a location somewhere in London. Harry gave them back for further investigation, thinking that they might be a trap, Dumbledore took them back but didn't activate the portkey. It's possible that this was just a short reference, meant to establish Dumbledore's steps of trust in parallel to the gift of the Cloak of Invisibility, and that Harry did not retrieve the portkey and Dumbledore did not place it upon Harry's person... But activation trigger was to rip the King of Hearts -- a king card known for its face character stabbing itself in the back of the head -- in half.

5Bound_up
I vote Dumbledore; he's a clever schemer. Dumbledore wants to give Harry his cloak, but decides to capitalize on the opportunity. He delivers it anonymously with a note telling Harry not to trust Dumbledore. Upon meeting Dumbledore, this allows him to impress Harry by deducing the nature of his cape, and then show his trustworthiness. Furthermore, he can comment on the potentially pure motives of the mud-slinger. Harry is alternately ashamed of his distrust of Dumbledore, and impressed with Dumbledore's charity and kindness, +2 to Dumbledore.
3gattsuru
It's not been explicitly confirmed, but given the similarity in forms to later notes signed Santa (and confirmed to be Dumbledore), the note's writer claiming the Cloak was freely given by Harry's father, and the explicit warning against letting Dumbledore see the Cloak, it's very likely that Dumbledore gave Harry the Cloak as in canon.

I'm so cross with Voldemort! How could he have possibly left Harry with the wand? How could he?

The game was going to last all night, it would have been so easy just to use up all the hours. Why did he wait for last words?

Dumbledore is not dead, just stuck in time. Maybe. Can't Harry get the time turner messaging squad to give Dumbledore advance notice of everything that will occur, so that he can set the mirror trap to be not so much of a trap? Dumbledore did seem to be very insistent on how Quirrell had fooled him and he had no idea whatsoever that Quirrell was Voldemort.

They're going to have to reveal Dumbledore's death anyway, and Quirrell =/= Voldemort would be the default assumption for any uninitiated observer anyway, seeing as their dead bodies were within metres of each other.

To me, the scene looked as though Quirrell had tried to fight Voldemort and the Death Eaters. Perhaps the story is that Quirrell killed the Death Eaters, Voldy killed quirrell, tried to sacrifice Hermione in a dark ritual, but Hermione's purity killed him. Or cut that last step, and make it that Harry snapped his fingers.

Because it's hard to be seen as on the light side when you decapitate 38 adult wizards in an instant? Fame is harmful, not helpful, to Harry's goals. Better to make it look like Voldemort managed to cause a magical backfire that killed all his minions in a failed ritual involving Hermione. To go back to the Azkaban chapters, the perfect crime is the one that is declared a tragic accident and closed.

Is that true? Harry wishes to reform or replace the government of Magical Britain, and being the hero who defeated Voldemort twice would make that a lot easier (as Voldemort himself acknowledged). Turning Hermione into the Girl-Who-Lived dilutes that effect, and also brings all his fame-related problems down upon her.
5Oshi
Harry at this point trusts Hermione's judgement far more than his own. Putting Hermione in the position of power as the girl-who-lives-again pushes her into the forefront, letting her be the head that Magical Brittain needs, leaving him to go about his business determined to not destroy the world, as his unbreakable vow requires.
2Velorien
With all due respect to Miss Granger, she would make a terrible politician. Her strengths are an amazing memory, academic talent, and an unbreakable moral compass. However, she has no skill at manipulation, poor social skills in general, and no special ambition or vision. The Malfoys of this world would run rings around her. By contrast, Harry is an unstoppable force for change in whatever direction he seeks, and his only real weakness is being too immature to properly weigh up the potential consequences of his actions. Which, admittedly, is a humongous flaw, but with recent events he finally knows that.

I don't see her making the shift out of that perspective fast enough to fully capitalise on Voldemort's defeat the way Harry would. (and let's not forget the various flavours of psychoogical trauma she may now be suffering from)

Data point - were I to interact with harry, I would likely see him as dangerously incompetent or a powerful enough optimizer to be a threat. Politicians probably don't want to be lumped into these mental buckets

Is it really that much better than being the hero who defeated Voldemort once, though? Putting on Hermione does seem pretty mean, but I think it's a very in-character sort of mistake, especially after the kind of day he's had.

I'm wondering whether Harry believes himself to be a threat to the world at this point in time. This would be a plausible reason for him to be setting Hermione up to take the credit for killing Voldiemort.

Other than modesty, letting Hermione take credit is a very elegant solution to a slew of problems: he can say that House Potter owes her no enmity after her defeating of their common foe, and this gets rid of any lingering doubts about her attacking Malfoy (probably...).

For me chapter 114 was all I wanted it to be (and possibly more) and chapter 115 was lovely.

I did stop thinking at "so he could transfigure a tip of his wand or maybe his fingernail into a nanotube, but I have no idea what he could do with that, because there is practically no way for him to talk his way out".

I didn't really check the LessWrong thread earlier, but I am happy to see that people here are a lot less willing to accept the unsatisfying solution than at r/HPMOR.

I used to really enjoy HPMOR, but it is now basically ruined for me - Voldemort holding the idiot ball, the one time where things really matter, and this is also when Harry's untested strategies work like a charm on the first try without him being noticed? I guess I was too quick to praise Eliezer on being able to write more believable scenes than Rowling.

What disappoints me almost as much is that the original answer was (from all that I can gather) to mainly just use the swerving hex. Hahahaha.

I'm pretty sure the original answer always had the partial transfiguration / nanotubes / garotte element. Consider the bit at the very start of chapter 1 (fraction of a line, robes falling, blood); the fact that in H&H's transfiguration experiments they use nanowires, verify that they're very strong, and verify that their length can be changed by transfiguration; arguably the bit in chapter 7 where Harry thinks what a good idea it would be just to decapitate all the Death Eaters; Dumbledore's insistence that partial transfiguration, being a power the Dark Lord knows not, may be vital to his victory.

While I am inclined to agree with the general spirit of your comment, I think you're being a little harsh. This is still miles more believable than much of Rowling's work. For one thing, recall that her Voldemort achieved the same terrifying results during the Wizarding War while being an idiot all the time.
3Tenoke
Yes HPMOR has been generally more believable, except for the one scene that matters in the whole book. At any rate, I am not sure if defeating Voldemort by use of an artefact - the Elder Wand is any less believable than using transfigured nanowires in secret against a much smarter version of Voldemort who forgets to use shields/wards/attention in order to catch harry this one time, and lets him have his wand when he doesn't need it.
0gjm
I wouldn't make that assumption. There are several chapters left and a bunch of things left unresolved, some of which seem like they could be important. Is he going to make further progress on defeating Death? Will we discover why there's a prophecy that he'll tear apart the stars, empty the skies, and end the world? Maybe not; there might be nothing left now but wrap-up. But I don't think it's a foregone conclusion.
[-]lerjj10

So... what we should do now is to work out all the things Quirrell should have before this. He couldn't predict partial transfiguration, true. But he knew that Harry had a power he knew not, and had a long time to plan for contingencies.

Personally, I think he should have had the death eaters disillusioned, surround Harry but from a distance, cast holograms to confuse him and then use ventriliquo charms. At the very least disillusionment should be as much of a general tactic as a massed finite and the death eaters could have been hidden.

When did Harry learn Obliviate?

Reply
[-]MarkusRamikin160

Chapter 90:

even a simple Obliviation will stretch the edge of your current stamina. It is a dangerous art, illegal to use without Ministry authorization, and I would caution you not to use it under circumstances where it would be inconvenient to accidentally erase ten years of someone's life. I wish I could promise you that I would obtain one of those highly guarded tomes from the Department of Mysteries, and pass it to you beneath a disguised cover. But what I must actually tell you is that you will find the standard introductory text in the north-northwest stacks of the main Hogwarts library, filed under M.

So there is no defense against Obliviation that Voldemort could have prepared for himself?

I confess I expected paranoid-Moody thinking from Harry, not Far-mode Good thinking. The stakes are so high that anything other than ruthless pragmatism feels insane to me.

One defense against obliviation would be to keep creating old-school horcruxes at regular intervals. As I understand they contain snapshots of current mind-state so should be unaffected by the main copy getting obliviated later. He might not be quite gone yet.

Like those 30 year old infectious samples of smallpox that keep turning up in NIH/university/etc freezers.

Wait, they do? Should I be worried?
0NancyLebovitz
They do show up. It's a risk, but so far I'd say it isn't something to be very worried about. Modern civilization doesn't seem to be too bad at dealing with infectious diseases.
0TobyBartels
OK, I'll trust the institutional descendants of whoever lost track of the virus samples to contain and destroy the virus samples. They'll probably be paying closer attention now. As long as none are mislabelled and thrown into the general trash.
0NancyLebovitz
Actually, I meant that even if people get infected (not very likely), I'm willing to be that modern civilization could contain and end the problem before a significant number of people got infected.
0TobyBartels
That's probably true too, but I'd hate to think what would happen if it it got loose in place with a less capable medical system, like Guinea.

So there is no defense against Obliviation that Voldemort could have prepared for himself?

With perfect sight toward the future, perhaps he could have. It's far from convincing that it would have actually helped, without blocking thirty other vulnerabilities.

Obliviation's particularly interesting because it requires no upkeep, but it's far from the only thing that would bypass Horcruxes. Voldemort's just as vulnerable to being repeatedly stunned, to petrification (hence the murder of the basilisk), to transfiguration, to the Imperius, to pretty much any mind-affecting charm. The biggest defense is, well, the same as anyone else's defense to the Killing Curse -- don't be there. Creating a defense specifically against large-scale Obliviation isn't very valuable if the attacker has countless further options to permanently disable anyone so defenseless as to be vulnerable to an Obliviate.

I would have thought he would rig up some dead-man's handle which explodes, killing him, if he is ever knocked unconscious. However, he would have to deactivate it when going to sleep, so he would still be vunerable then.
0buybuydandavis
Besides all the foreshadowing about Quirrell's plan being to lose a battle to Harry, isn't it rather convenient that Quirrell just happens to arrange for Harry to learn the spell that Harry uses to defeat him?
2MathMage
Not really. Mind magic is one of Harry's top priorities, Quirrell is the first person he'd ask about Obliviate, Quirrell has no reason not to tell him, and Obliviate wasn't exactly the spell Harry used to defeat Quirrell in the first place. This outcome is about as likely in the world where Quirrell wasn't expecting to lose as in the world where he was, so it doesn't shift the priors substantially.

"the stunbolt leapt out of her wand and -

  • slowed to a stop in front of Professor Quirrell's raised hand, rippling in midair like it was still trying to fly and making a slight hissing sound."

Does LV really need hands to stop stunbolts? Why did he try to evade?

Resonance. He doesn't dare involve himself with Harry's magic in any way.
1gattsuru
He'd just been attacked by a magical source that disarmed his weapons at the wrists, was cast wordlessly and without wand motions, and did not leave an obvious bolt to block. This is probably a bad time to show off. At a deeper level, Voldemort (and Mad-Eye Moody) favor a combat philosophy of dodging, under the quite reasonable realization that there are a large number of spells that can overwhelm shields or are unblockable.

Am I wrong in thinking that Voldemort had given his gun to one of the Death Eaters, and so Harry should not be seeing it fall alongside Voldemort's wand when he cuts his hands off?

From 113: So it was planned, but never executed. All other references to the gun have it in Voldemort's hand.
[-]DanielLC00

We were told to keep Harry from dying immediately. The actual solution had Harry winning. I guess the moral of the story is that if you figure out how to accomplish what you wanted, don't stop thinking. Figure out how to accomplish more.

Harry said that he had to kill the Death Eaters. I disagree. There are ways he could have incapacitated them. Probably. My plans killed them all too, because their lives weren't worth the increased chance of failure.

I think Harry should have tortured Voldemort to insanity and then obliviated him. That way if the obliviation doesn't stick, Voldemort would still be tortured to insanity.

Unfortunately Harry hasn't learned the Cruciatus Curse.
1Astazha
This sounds less safe because you'd need to wake him up to torture him into insanity. If you wanted the multiple layers you could torture the obliviated version into insanity, but I think I prefer the transfiguration. I'd even consider making it permanent with the Stone of Transfiguration, but this would result in a lot of lost knowledge and it's also possible that the horcrux network would consider it a death. ETA: I rather liked the wand-in-a-dementor-pit idea.
0TuviaDulin
Safest option would have been the dementor's kiss. Or, if the kiss isn't a thing in MoRverse, tossing his wand to them as Harry had mused.

Isn't Voldemort's body going to die in its Transfigured form? I assume Harry has a way around that, and he has a reasonably long time frame to implement a solution (at least compared to the 60 seconds he had to work with just now), but that dangling loose end is gnawing at me.

Reply
3MarkusRamikin
If I understand correctly, you only suffer from transfiguring yourself or parts of yourself after returning to your original form, after the transfiguration stops being sustained and wears off. Bolding mine. The Stone solves that. Assuming Harry grabbed it, which seems like a no brainer but I don't think was ever explicitely mentioned that he did. EDIT: Aha, it was edited in just now.
0MathMage
Whoops, that's, right. Thanks.
1jkadlubo
It's the same as with Hermione's body and the unicorns. They are stones as long as they are Transfigured. When Transfiguration stops, they will soon suffer. That's why Harry kept Hermione's body and now thinks about sustaining the Transfiguration of Voldemort all the time - he wants them to stay Transfigured until their state can be helped. He's kind of frozen now.
0MathMage
Ah, thanks.

Quick note:

Harry's eyes only saw the Dark Lord's hands and wand and gun dropping downward, and then Harry's wand was rising, pointing -

Harry screamed, "STUPORFY!"

It's only fair. We've spent the last few days brainstorming ways to save Harry, and our work has paid off after a fashion. Now we have the leisure to reflect on the situation from a different angle.
