How about improving kiai-cry. I know it shouldn't be as powerful as Battlecry
but I think it shouldn't be next to useless either. Make it a little more
powerful, but never as powerful as battlecry. Vital Points could also affect
to how powerful kiai-cries one gets. Barbs require reputation to make good
battlecries so monks could require lots of exp so you can train those vital
points and get good kiai-cries.

Well, if you were highly skilled you'd understand how um...to er...scare
people....or uh..something. Blah blah. Bored-grad.
