Luminosity!Bella's shield also has some sort of an enhanced-immortality power
If you want to phrase it that way, I suppose it's an okay label. When the existence of her mind is in danger, the shield will force her body into the minimum adequate configuration for her mind to go on existing, but it's not omnipotent. She would have died if it had been a long time since her last feeding, or if her pieces had been scattered over a square mile or more before being set on fire, or if she'd just been ignited again after the flames went out.
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.)
