Staggering Critical

Prerequisites Critical Focus, base attack bonus +13.

Benefits

Whenever you score a critical hit, your opponent becomes staggered for 1d4+1 rounds. A successful Fortitude save reduces the duration to 1 round. The DC of this Fortitude save is equal to 10 + your base attack bonus. The effects of this feat do not stack. Additional hits instead add to the duration.

Special

You can only apply the effects of one critical feat to a given critical hit unless you possess Critical Mastery.
