Corrosion

You corrode a nonmagical object of Diminutive size or smaller within range of the spell. That object instantly turns into grains of dust. If the target is a Small or larger object, this spell corrodes a portion of it equal to a 2.5-foot cube. A magic item is unaffected by this spell.

A creature wearing or carrying the object affected by the spell must make a Dexterity saving throw. On a failure, the creature takes 4d6 disruptive damage.
