SRD:Psychic Crush

Your will abruptly and brutally crushes the mental essence of any one creature, debilitating its acumen. The target must make a Will save with a +4 bonus or collapse unconscious and dying at –1 hit points. If the target succeeds on the save, it takes 3d6 points of damage.

Augment: For every 2 additional power points you spend, this power’s damage increases by 1d6 points.
