Appeal to the creatures' most basic instinct to even the playing field. If there are more allies or enemies, a number of creatures within 60' of you that fail a Charisma saving throw equal to the difference are charmed, if they can be, and prevented from engaging in combat for the duration. If you cannot make an even number of allies and enemies through this means, this spell fails. For every hostile enemy that leave the area of effect or perishes, a random charmed enemy becomes hostile again.
