Damage Reduction (DR)
A special defense that allows a creature to ignore a set amount of damage from most weapons, unarmed attacks, or natural weapons, but not from energy attacks, spells, or spell-like abilities. The number in a creature’s damage reduction is the amount of hit points of damage the creature ignores. The information after the slash indicates the type of weapon (such as magic, silver, or good) that overcomes the damage reduction. Some damage reduction, such as that of a barbarian or some elementals, is not overcome by any type of weapon. Example: A creature with DR 5/Bludgeoning ignores the first five points of incoming damage unless the source is a bludgeoning weapon.
