Your quick movements and rapid utterances release the spell’s energy, culminating in a final cry that unleashes a tremendous bolt of sonic energy from your open hand.
The bolt of sonic energy deals 1d4 points of sonic damage per caster level (maximum 10d4) to each creature within its area. In addition, a resonating bolt deals full damage to objects and can easily shatter or break interposing barriers. If the bolt destroys a barrier, it can continue beyond the barrier if its range permits; otherwise, it stops.
