Master of Metal

Choose up to ten unattended metal objects within range, each weighing no more than 250 pounds. As a bonus action while the effect lasts, move any number of them up to 40 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 36 (8d8) bludgeoning, piercing, or slashing damage and may be pushed or pulled 15 ft.
