Damage Resistance/Fallout: The Roleplaying Game

Damage Resistance is a derived statistic $$

Gameplay
In Fallout: The Roleplaying Game, Damage Resistance (DR) is determined by perks and equipment. There are four distinct types of Damage Resistances, all of which are subtracted from damage dealt before health is reduced. All base Damage Resistances start at 0.
 * Physical Damage Resistance protects against unarmed attacks, blunt force, stabbing and slashing and ballistics.
 * Energy Damage Resistance protects against laser, plasma and flame-based weaponry.
 * Radiation Damage Resistance protects against latent Radiation or Radiation-based weaponry.
 * Radiation Damage will reduce a character's maximum Health Points after subtracting the damage dealt. If the Health Point maximum is reduced below a character's current HP, their HP is reduced as well. If a character suffers from Radiation Damage and another type of Damage at the same time, the Radiation Damage is applied after.
 * Poison Damage Resistance protects against toxins, chemicals or creature stings or barbs, such as from Radscorpions or Stingwings.
 * Poison Damage is not affected by location; a character or creature has a single Poison Damage Resistance value. Mutations, chems and consumables can also increase this value.
