Although it's not demonstrated in the books, Edward can in theory get around Alec. Alec's power works slowly and moves through space; by reading where it's going to be, Edward could just get out of the way. Jane's faster, so he can get gotten by her. Jane cannot, however, singlehandedly destroy a coven, because she's limited to one target at a time and not especially powerful physically.
I take it that the same applies to Alice? I assume she gets her foresight at the same time that Edward gets his mind reading. That would leave her vulnerable to Jane but not (overwhelmingly) vulnerable to Alec.
How fast can Jane switch targets? Is it crucio Fred... then switch to crucio George and Fred gets up while George falls down in pain? Or does she need to recharge?
Either way crucio; molotov jumps out as her obvious default combat strategy (where prisoners are not desired). Vampire reflexes would (I assume) make flame based projectiles mostly ineffect...
In the vein of the Harry Potter and the Methods of Rationality discussion threads this is the place to discuss anything relating to Alicorn's Twilight fanfic Luminosity. The fanfic is also archived on Alicorn's own website <strike>(warning: white text on black background)</strike>.
Previous discussion is hidden so deeply within the first Methods of Rationality thread that it's difficult to find even if you already know it exists.
Similar to how Eliezer's fanfic popularizes material from his sequences Alicorn is using the insights from her Luminosity sequence.
Spoilers for the fanfic itself as well as the original novels need and should not be hidden, but spoiler protection still applies for any other works of fiction, except for Harry Potter and the Methods of Rationality chapters more than a week old so we can freely discuss similarities and differences.
EDIT: Post-ginormous-spoiler discussion should go to the second thread. (If you have any doubt on whether you have reached the spoiler in question you have not.)
