Doom Charge p. 58
Devoted Spirit [Evil]
You cloak yourself in a black, terrible aura of contempt and spite.
You must make a charge attack as part of this maneuver. If your target is good-aligned, your attack deals an extra 6d6 points of damage. In addition, if your charge attack hits and the target is good-aligned, you become wreathed in unholy energy. You gain damage reduction 10/- until the beginning of your next turn.
