Brogue Wiki
This potion will render you impervious to heat and permit you to wander through fire and lava and ignore otherwise deadly bolts of flame. It will not guard against the concussive impact of an explosion, however.

This potion makes you the Immune to Fire for 150 turns. Beware of using Potions of Fire Immunity to walk through lava - if an enemy spellcaster casts Negation on you, your fire immunity will be removed and you will instantly burn to death.
