Pretty much what the title says. Is there any published content (or combination thereof), whether a class feature, spell, feat, racial trait, magic item or whatever that would let a character by healed instead when taking elemental damage? I'm mostly interested in Fire damage, but if it's only possible with some other element that's also fine.
This needs to be for a player character. I know there's some monsters that can do it, but they're not playable.
