Vorpal Projection

You create a floating, spectral glaive within range that lasts for the duration or until you cast this spell again.
When you cast this spell, you can have the spiritual weapon make an attack against a creature within 5 feet of it. On a hit, the target takes force damage equal to 2d8.

As a bonus action on your turn, you can move the weapon up to 20 feet and repeat the attack against a creature within 5 feet of it.
