(General)
You can dramatically increase your damage reduction in exchange for its temporary loss.
Prerequisites
Damage reduction.
Benefit
As an
Immediate Action, you can double your DR against a single attack, to a maximum of DR 20. The type of the DR remains unchanged. If the attack you are guarding against is not successful, the increased
Damage Reduction persists until you are hit with an attack or until the start of your next turn, whichever happens first. At the start of your next turn, you become
Fatigued. You cannot use this feat while you are
Fatigued.
