Least Invocation; 2nd
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.

Shatter creates a loud, ringing noise that breaks brittle, nonmagical objects; sunders a single solid, nonmagical object; or damages a crystalline creature.
Used as an area attack, shatter destroys nonmagical objects of crystal, glass, ceramic, or porcelain, such as vials, bottles, flasks, jugs, windows, mirrors, and so forth. All such objects within a 5-foot radius of the point of origin are smashed into dozens of pieces by the spell. Objects weighing more than 1 pound per your level are not affected, but all other objects of the appropriate composition are shattered. Alternatively, you can target shatter against a single solid object, regardless of composition, weighing up to 10 pounds per caster level.
Targeted against a crystalline creature (of any weight), shatter deals 1d6 points of sonic damage per caster level (maximum 10d6), with a Fortitude save for half damage.
Arcane Material Components: A chip of mica.
