Convergence

By compressing your blood, you may condense it to its limit. On your turn, as an action, you may compress your blood into blood orbs that hover around you and follow you. Your number of blood orbs may not exceed your Charisma modifier. On your turn, as a bonus action, you may move 1 blood orb up to 20 feet. Alternatively, as a bonus action you may command any of your blood orbs to return to hovering around and following you. If any of your blood orbs are more than 120 feet away from you, it immediately loses its cohesion and turns back into regular blood.
