Arcane Sword

You create a sword-shaped plane of force that hovers within range. It lasts for the duration.

When the sword appears, you make two melee spell attacks against a target of your choice within 5 feet of the sword. On a hit, the target takes 3d10 force damage. Until the spell ends, you can use either an action or a bonus action on each of your turns to move the sword up to 20 feet to a spot you can see and then make up to two melee spell attacks with it again.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the damage increases by 1d10 for every two slot levels above 7th.
