You can channel divine energy to turn your foe's strength against him, striking him with the same force that he used against you.
Prerequisite: Ability to turn or rebuke undead.
Benefit: As a swift action, you can expend a turn or rebuke undead attempt to mark an opponent as the target of this feat. The next time this opponent strikes you with an armed melee attack or a natural weapon, record the damage he deals. The next time you strike him in melee, you deal that damage or your weapon's normal damage, whichever is greater. Your weapon's qualities still determine if damage reduction applies to the damage you deal. You can mark only one opponent at a time with this feat. You must take damage from your foe within 1 minute of using this feat, or you turn or rebuke undead attempt is wasted. After taking damage, you must strike your foe within 1 minute, or you lose this feat's benefit. Until you strike your foe and trigger the feat's benefit, you cannot use this feat again to mark the same or a different opponent.
