Blitz of Blades

You point the weapon in your hand towards a creature in range, two copies of the weapon appear around the target. For each copy of the weapon make a melee weapon attack against the target. On a hit, the target suffers the attack’s normal effects. After all the attacks are made the copies all disappear.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, an additional copy of the weapon appears around the target for every two slot levels above 3rd.
