Void's Embrace

You can channel the otherworldly energies of the void, creating a 30 foot sphere of magical darkness centered around yourself, which functions as per the Darkness spell except it does not affect you. Additionally, each hostile creature within 30 feet of you must make a Constitution saving throw. A creature takes psychic damage equal to 2d10 + your Cleric level on a failed saving throw, and half as much damage on a successful one
