Shatter

The shatter spell is a sound-based attack that affects nonmagical objects of crystal, glass, ceramic, or porcelain, such as vials, bottles, flasks, jugs, windows, mirrors, etc. All such objects within a 3-foot radius of the center of the spell effect are smashed into dozens of pieces by the spell. Objects weighing more than one pound per level of the caster are not affected, but all other objects of the appropriate composition must save vs. crushing blow or be shattered. Alternatively, the spell can be focused against a single item of up to 10 pounds per caster level. Crystalline creatures usually suffer 1d6 points of damage per caster level to a maximum of 6d6, with a saving throw vs. spell for half damage. The material component of this spell is a chip of mica.
