Shatter creates a loud, ringing noise that shatters 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. All such objects within a 3-foot radius of the point of origin are smashed into dozens of pieces by the spell. Objects weighing more than 1 pound per the character's level are not affected, but all other objects of the appropriate composition are shattered.
Alternatively, the character 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 damage per caster level (maximum 10d6), with a Fortitude save for half damage.
