To Arms

You extend the reach of an unseen hand to a weapon, allowing you to wield it against your enemies. Choose an unwielded melee weapon within range. It begins to levitate as if being held, allowing you to immediately make a spell attack against a target within 5ft. of the weapon. On a hit, the target takes the weapon's typical damage.

Using your bonus action on subsequent turns, you can cause the weapon to move up to 30ft. and repeat this attack.
