Damage Reduction( Epic Level Handbook, p. 52)
You can shrug off some damage from attacks.
You gain damage reduction 3/-. This does not stack with damage reduction granted by magic items or nonpermanent magical effects, but it does stack with any damage reduction granted by permanent magical effects, class features, or this feat itself.
A character can gain this feat multiple times. Each time you gain the feat, your damage reduction increases by 3.
