You complete the spell with a scream, and echoes of your cry travel outward and burst into ear-shattering sounds.
You cause a burst of low, discordant noise to erupt at the chosen location. It deals 1d6 points of sonic damage per caster level (maximum 15d6) to all creatures within the area.
Cacophonic burst cannot penetrate the area of a silence spell.
