Fire Resistance

Requirements: Elemental Magic 2

This ability confers near-immunity to heat and fire. The character can survive
almost any hot temperature environment, and walk unharmed through fire; they
are still affected by smoke, however. While it does convey immunity to some
abilities, particularly pyromancy, it is primarily a roleplay-based stat. Note
that the character must be alive for this to work; their corpse can be burned
just as easily as anyone
else’s.

This does not help against hellfire.
