Arcane Sword

You summon an insubstantial yet deadly sword to do your bidding.

Make a melee spell attack against a target of your choice within 5 feet of the sword, dealing 3d10 force damage on a hit.

Until the spell ends, you can use a bonus action on subsequent turns to move the sword up to 20 feet to a space you can see and make an identical melee spell attack against a target.
