[Divine]

You can channel divine energy to deal extra melee damage to evil outsiders.

Prerequisite

Ability to turn or rebuke undead

Benefit

As a swift action, spend one of your turn or rebuke undead attempts to deal an extra 2d6 points of damage with all your successful melee attacks against evil outsiders until the end of the round. In addition, evil outsiders struck by one of your attacks while you are using this feat must succeed on a Will save (DC 10 + 1/2 your character level + your Cha modifi er) or be shaken for 1 minute.
