Telekinetic Swarm

You reach out and form five orbs out of surrounding material which orbit your body until the spell ends. You can, as a bonus action, fling one of the stones forward with great force towards one creature or object within 90 feet of you. When you do so, make a ranged spell attack. On a hit, the target takes 6d4 bludgeoning damage. If the attack lands the orb is destroyed, if it misses the stone returns to orbit around you. For every three orbs remaining in orbit around you, you have a +1 to Armor Class.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the number of orbs created increases by 1 for each slot level above 5th.
