Blade Barrage

You create three floating, spectral blades that lasts for the duration or until all blades are expended. They float in the air and orbit you or the spells duration. When you cast the spell-and as a bonus action of each of your turns thereafter-you can expend one or two blades sending them streaking toward a point or points you choose within 60 feet of you. Make a ranged spell attack with each blade sent. On a hit, the target takes force damage equal to 1d10 + your spellcasting ability modifier and the blade shatters into mist. The weapons can take whatever form you choose as long as the weapon deals piercing or slashing damage. 

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, another blade is formed for every slot level above 3rd level.
