Babbling Banshee

Upon casting the spell on a creature you can see, all creatures within a 20' radius of the center must make a Charisma Saving Throw. Any creature that fails to save will fall prone and begin wailing incoherently for the duration of the spell. If a creature is hit while in this prone state they must reroll there charisma saving throw to see if the spell is broken for the creature being hit.
