Crack

When you cast this spell, you create a small orb of ice. When this ball hits any creature or surface, any creature (including yourself) within a 15 foot radius of the orb must make a Dexterity saving throw and are dealt 3d6 cold damage on a failed save or half as much on a successful one. If you're attacked while holding this orb, you must make a Dexterity saving throw equal to your spell save DC or you drop the orb and the pervious effect takes place.
