Object Swarm

Animate a swarm of Tiny unattended objects in a 10-ft. radius sphere centered on a point within range. The area is difficult terrain. When a creature enters the area for the first time on a turn or starts its turn there, it must make a DEX save, taking 7 (2d6) bludgeoning, piercing, or slashing damage on a failed save, or half as much on a success. As a bonus action, you may move the swarm up to 20 ft.
