|“||Reduces poison damage by this amount.||”|
—Fallout game description
Fallout, Fallout 2, Fallout Tactics
- The Fast Metabolism trait sets initial poison resistance to 0.
- The Snakeater perk increases poison resistance by 25% per rank.
- The Vault City Inoculations perk increases poison resistance by 10%.
Poison Resistance is also present in Fallout 3. It has a much smaller part than in the previous games since only a few enemies (Radscorpions chief among them) use poison, and poison effects tend to be weak.
Example: A starting Endurance of 5.
- The Cyborg perk can increase resistance by +10%.
- The Survival Expert perk can add between an additional +2% to +6%.
Fallout: New Vegas
Fallout: New Vegas uses the same equation as Fallout 3, but Poison Resistance has much more use: there are cazadores, bark scorpions, night stalkers, and weapon poisons, all in addition to radscorpions. In Lonesome Road, there are also venomous tunnelers. Moreover, poison in Fallout: New Vegas is generally much more lethal.
Honest Hearts perks
- Tribal Wisdom increases the poison resistance by 25%.
Old World Blues perks
- Mile in Their Shoes - after consuming the nightstalker squeezin's, poison resistance is increased by 5%.
