Metal Command

Choose up to five unattended metal objects within range, each weighing no more than 100 pounds. As a bonus action while the effect lasts, move any number of them up to 30 ft. If you drive objects into a creature, make one ranged power attack against a target within 30 ft. of at least one controlled object. On a hit, the target takes 27 (6d8) bludgeoning, piercing, or slashing damage.
