Psychological Warfare (3.5e Maneuver)

Your terrifying visage breaks your opponent's will just as your blade pierces their defenses.

Your intimidation abilities have the ability to strike opponents dumb. On a successful attack, make an Intimidate check. If you succeed, your opponent incurs a 1d6 penalty to their Intelligence, Wisdom and Charisma damage for 1 round per two initiator levels. This maneuver cannot reduce any ability scores below 1.
