You speak a single syllable of the Dark Speech (described in Book of Vile Darkness), affecting an object or area as if by a shatter spell. If a creature is holding or wearing the target of the spell and the target is destroyed, the creature must make a Fortitude save or be dazed for 1 round and deafened for 1 minute by your terrible word. This is a sonic effect.
