You animate droplets of your own blood to act under your command. For every three hit points spent in the casting of this spell, you create a droplet of animated blood. As you cast the spell, and as a bonus action on each of your turns thereafter, you can mentally command the droplets to move as long as they are within 120 feet of you. The droplets have a speed of 30 feet, and a climbing speed of 15 feet. As an action on your turn, you can choose to see and hear from the location of one of the blood droplets until the end of your turn, becoming blinded and deafened to your own surroundings. Additionally, you may instead use your action to cause one of the droplets to explode in a burst of necromantic energy, destroying the droplet and damaging surrounding creatures. Each creature within 5 feet of the droplet must make a Dexterity saving throw. A creature takes 6d4 necrotic damage on a failed save, or half as much damage on a successful one.
