Your teeth extend and sharpen, transforming your mouth into a maw of razor-sharp fangs. You gain a bite attack that deals 1d4 points of damage plus your Strength modifier. If you confirm a critical hit with this attack, it also deals 1 point of bleed damage. If you already have a bite attack, your bite deals 2 points of bleed damage on a critical hit. You are considered proficient with this attack. If used as part of a full-attack action, the bite is considered a secondary attack, is made at your full base attack bonus –5, and adds half your Strength modifier to its damage.

You can end this spell before its normal duration by making a bestial roar as a swift action. When you do, you can make an Intimidate check to demoralize all foes within a 30-foot radius that can hear the roar.
