Secret of the Ferocious Shout
The Zaru, who have practiced unarmed combat styles for centuries, can utter a terrifying bellow to focus their martial prowess. When a character with this secret decides to Bring Down the Pain using a martial arts style, she can yell at the top of her lungs at the start of combat and thereby replenish her Vigor.

This is really powerful, but I dig it. I think to balance it - plus the combo of word power and martial arts is cool - I'd add a prerequisite of the Secret of Zu/Uz. -- Clinton R Nixon
