Description: You gain a hideous smile full of razor-sharp teeth that enable you to make a grisly bite attack.

Prerequisites: Evil Alignment

You gain a bite attack that can be used as a natural weapon to deal damage equal to 1d4 + your Strength modifier. If you attack with other weapons, you can use your bite as a secondary attack (taking a -5 penalty on your attack roll) for 1d4 + half Strength modifier damage. In addition, you gain a +1 bonus on Intimidate checks.
