PIERCING HOWL | Su

Gene Pool -3 | Disguise DC Modifier +0

You can alter your voice to emit a high-pitched, piercing scream that can deafen nearby enemies and allies.  You can emit a piercing howl, which can be heard at a range of up to 10 miles. All characters and creatures within 60 feet and the ability to hear must make a Fortitude save (DC 11 + your level), or be deafened for 2d6 rounds. Furthermore, any crystal or glass objects must also save or shatter as a result of the intense sonic vibrations caused by the piercing howl.

Any creature with augmented hearing suffers a -2 penalty on its save.

Evolution I:  The base DC of your piercing howl is increased to 13. 

Evolution II: The base DC of your piercing howl is increased to 15.
