Great Ki Shout( Oriental Adventures, p. 63)
Your ki shout can panic your opponents.
Ki Shout (OA) , CHA 13, Base attack bonus +9,
When you make a ki shout, your opponents are panicked for 2d6 rounds unless they succeed at their Will saves (DC 10 + 1/2 your character level + your Charisma modifier). Panicked characters suffer a —2 morale penalty on attack rolls, saves, and checks, they have a 50% chance to drop what they are holding, and they run away from you as quickly as they can. The effects of being panicked supersede the effects of being shaken.
