Cube Strike

You create six tiny metal cubes in your space. They float in the air and orbit you for the spell’s duration. When you cast the spell — and as a bonus action on each of your turns thereafter — you can expend one or two of the cubes, sending them streaking toward a creature or creatures within 120 ft. of you. Make a ranged spell attack roll. On a hit, the target takes 3d4 magical bludgeoning damage.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the number of cubes created increases by two for each slot level above 3rd.
