Fire Resistance

Fire Resistance allows you to resist fire. The higher your Fire Resistance, the less damage you incur from fire-based attacks, such as from Fire Ants, or from enemies using fire-based weapons like the Flamer, Heavy Incinerator, and the Shishkebab.

Fallout 3

 * The Ant Might or Ant Sight Perk can be aquired from Doctor Lesko during the course of the Fallout 3 quest Those!. Either perk grants +25% Fire Resistance.
 * Enclave Hellfire Armor grants a +30% Fire Resistance and the Enclave Hellfire Helmet a +5%.
 * Applying Fire Ant Nectar will increase Fire Resistance by 25%.

If one has all three of the aforementioned flame-retardant abilities, the total will be 85% fire resistance, making enemies such as Enclave Hellfire troopers or Fire ants little to no problem.

Fallout: New Vegas

 * Applying Fire Ant Nectar will increase Fire Resistance by 25%.
 * Using Gecko-backed armors from Honest Hearts will increase by 15%.
 * The Scorched Sierra power armor from Lonesome Road increases fire resistance by 25%.
