Arcane Sword A5E
7th-level evocation
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.
