As an action, you touch a single metal or stone object that is up to two cubic feet and turn it to fragile crystal. This change is permanent.

If the target is a creature or if it is worn or held, make a melee spell attack. If the target is a magical item that is carried or worn, the owner of the item can attempt a Dexterity saving throw to avoid the effect.
