Forced Serenity

You imbue creatures with lingering psychic energy, crippling them with pain at any sign of aggression. Choose a point you can see within range. Creatures within a 20-foot Radius centered on that point must make a Charisma Saving Throw, taking 4d10 Psychic damage on a failure, or half as much on a success. On a failed save, for the duration, an affected creature takes Psychic damage equal to your Manifesting Ability Modifier whenever it deals damage to a creature. It takes this damage for each creature it damages in the case of an effect that targets multiple creatures, like a Fireball spell.   At the end of each of the affected creatures' turns, they can repeat the saving throw, ending the effect on a success.
