You emit an ear-splitting yell that deafens and damages creatures in its path. Any creature within the
area is deafened for 2d6 rounds and takes 5d6 points of sonic
damage. A successful save negates the deafness and reduces the
damage by half. Any exposed brittle or crystalline object or crystalline creature takes 1d6 points of sonic
damage per
caster level (maximum 15d6). An affected creature is allowed a Fortitude save to reduce the
damage by half, and a creature holding fragile objects can negate
damage to them with a successful Reflex save.
