Thousand Cherry Blossoms

Your blade instantly shatters into a thousand slivers. They fall momentarily before floating upward. Red flames flare up around each individual piece, wreathing them in glittering fire. You use simple verbal commands (go there, attack them, return, etc) to direct the swarm of fragments to attack enemies. You may attack one enemy in your turn in this way, as a bonus action. As long as you hold concentration, the cherry blossoms fly into enemies within 30 feet. These enemies take 2d10 slashing damage and 1d6 fire damage on a failed DEX save, and half as much on a success. If any enemies approach within melee range of you, the fragments automatically return to you and fly in a swarm around you. You roll to maintain concentration, and the enemies take 2d10 slashing damage plus 1d6 fire damage on a failed DEX save, and half as much on a success. When the spell ends, or you lose concentration, your blade instantly returns to its normal state. Any effects like smite etc can be used on the fragments in this spell, while enchanted weapons do not retain their properties during this spell.
