Bristlechin's Fantastic Band

The caster summons magical interments that play music as the caster deems. As an action on subsequent turns, each creature of your choice in a 30ft cone has to make a WIS save or be charmed by you. When charmed in this way the creature must use its movement to move toward the band and begin to cheer once they are within 5ft of you they can't move away until the charm ends. At the end of each of the creature turns, it can repeat the save and on success is immune to the effect for 24 hours.
