Fire Resistance

Fire Resistance allows you to resist fire. The higher your fire resistance, the less damage fire-based attacks do. Your fire resistance can only be raised by some clothing, or the Ant Might and Ant Sight Fallout 3 Perks.

Enclave Hellfire Armor increases fire resistance greatly by +30

Fire Resistance is applied to any weapon dealing fire damage such as the Flamer, Heavy Incinerator, and the Shishkebab. The only enemy to do fire damage naturally is the Giant Fire Ant and it's variants.
