Turnabout

You know how to quickly turn a tide of steel back upon your enemies. Choose up to 12 weapons within range. These weapons may be unwielded, or currently being wielded by creatures you can see. If you choose weapons currently being wielded, the creatures wielding them may choose to make a Strength saving throw to resist the effects of this spell.

Affected weapons begin to levitate as if being wielded, making immediate attacks against the creatures from which they were taken. On subsequent turns, as a bonus action, you may have the weapons move up to 30ft. and repeat this attack. Each weapon must target the creature from which it was taken until that creature is either out of range, or reduced to 0 hit points, after which point you choose a new target for that weapon.
