Description: Your kiai shout can panic your opponents.

Prerequisites: CHA 13, Base Attack Bonus +9, Kiai Shout

When you make a kiai shout, your opponents are panicked for 2d6 rounds unless they succeed on Will saves (DC 10 + 1/2 your character level + your Cha modifier). The kiai shout affects only opponents with fewer Hit Dice or levels than you have.
