SRD:Ego Whip

Your rapid mental lashings assault the ego of your enemy, debilitating its confidence. The target takes 1d4 points of Charisma damage, or half that amount (minimum 1 point) on a successful save. A target that fails its save is also dazed for 1 round.

Augment: For every 4 additional power points you spend, this power’s Charisma damage increases by 1d4 points and its save DC increases by 2.
