Destroy Identity

You are able to use your weapons to destroy some of your opponent’s most distinctive physical characteristics.

Prerequisite: Critical Focus, base attack bonus +11, worshiper of Lamashtu.

Benefit: Whenever you score a critical hit against an opponent, the target is so maimed that it takes 2 points of Charisma damage and becomes staggered for 1 round. Rovagug The Rough Beast’s followers disdain complex combat, bowling over their enemies with displays of brute strength and overpowering will.
