Hand of Death p. 77
Shadow Hand
You reach out and tap your foe with a single finger. Her look of puzzlement turns to fear as black energy spreads across her body, rendering her helpless.
You draw upon the power of shadow to render a single foe helpless. By touching a specific nerve center and channeling your ki, you leave your enemy's muscles cold, locked, and useless.
This maneuver functions only against flat-footed opponents. As part of this maneuver, you make a melee touch attack against your opponent. If this attack hits, your opponent must make a successful Fortitude save (DC 14 + your Wis modifier) or be paralyzed for 1d3 rounds.
This maneuver is a supernatural ability.
