Interesting, I wonder if Imperius helps with following instructions, i.e. if you’re better at following (non-Imperius) instructions after X Imperiuses you to follow Y’s instructions, than if you just wanted to follow Y’s instructions at the same time. There are very probably spells that make you (temporarily) better in terms of dexterity and such. Hell, there’s Felix. If the PS recipe is correct, its difficulty should not be a problem for Harry. (At least if we assume Flamel actually did create one—which we’ve taken on trust until now—which implies it’s within (extreme) human bounds of ability.)
ahem: Felix is off limits in MoR.
"which we’ve taken on trust until now" -it's a cannon artifact, the (in)famous forbidden corridor is still there, the door can still be unlocked with alohamora, flamel wants his whatever hidden in hogwarts, Quirrlmort can (probably) find it wherever it goes...it's there. Whether it does EXACTLY what it does in cannon or not, or acts more like the one from Full-Metal Alchemist....is more of an open question, especially since elixir of life itself never makes an on-screen appearance in cannon.
But I'll give you this, the recipe doesn't have to be correct, since that's not in cannon as far as I know.
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 94. The previous thread has passed 200 comments.
There is now 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.)
