Say a level 20 human wizard named Dumbledore is tired of his hand hurting. Said appendage was damaged magically and cannot be cured by any known means (short of deity magic or a Wish spell, which apparently Dumbledore cannot cast). Will a permanent transformation of True Polymorph rid Dumbledore of the problem? Specifically, can a permanent True Polymorph:
- Cure injuries, including amputations (I'm guessing yes)
- Cure poisons, regardless of source (mundane, magical, etc)
- Cure disease, regardless of source (mundane, magical, etc)
- End curses, hexes, and similar effects
