There’s a book I read that takes place in Faerun where a cleric is getting tortured by ogre clerics by having his limbs broken and then they use heal spells to heal his limbs at odd angles. After he’s freed, they break his limbs again, heal them in braces, but he had a permanent limp
DnD healing can only do so much before its just some high power reality changing magic.
Exactly. If that adventurer wanted to “cure” what he saw as a flaw, he could quest for a much more specialized magical healer or more powerful spell to enable it. I mention greater restoration, but true polymorph to his original form, or some kind of time manipulation, etc. There are options, at a high enough toer of magic, to undo injury, but that power has to have been attained.
This is why amputations aren’t cured by a cure wounds. You can’t just grow a pile of pork by hacking into a live pig and repeatedly healing it.
