Your natural attacks are more vicious.
Benefit: The competence bonus from your trance now also applies to damage rolls made with natural attacks. In addition, when using the Feral maneuver, if two natural attacks in the same charge are successful, your natural weapons deal extra damage. This damage is equal to the damage dealt by one natural attack plus 1-1/2 times your Strength modifier (if the two natural attacks deal different amounts of damage, use the lesser of the two).
