Deafening Critical (Combat, Critical)Modifier
Your critical hits cause enemies to lose their hearing.
Prerequisites: Critical Focus, base attack bonus +13.
Benefit: Whenever you score a critical hit against an opponent, the victim is permanently deafened. A successful Fortitude save reduces the deafness to 1 round. The DC of this Fortitude save is equal to 10 + your base attack bonus. This feat has no effect on deaf creatures. This deafness can be cured by heal, regeneration, remove deafness, or a similar ability.
Essentia: The duration & the DC increase by +1 / Essentia
Special: You can only apply the effects of one critical feat to a given critical hit unless you possess Critical Mastery.
