Crown of the Summer Monarch

Effect: A crown of golden light appears above your head. For the duration, you gain advantage on all Charisma checks, and any creature that starts its turn within 60 feet of you must make a Wisdom saving throw, DC 15, plus your Charisma Modifier. On a failed save, the creature is charmed by you until the spell ends or until you or your companions harm it. While charmed, the creature regards you as its rightful sovereign and follows your commands to the best of its ability, though it won't harm itself in an obviously suicidal way, it will attack others on your order. A charmed creature can attempt a new saving throw at the end of each of its turns, ending the effect on itself on a success. A creature that succeeds on its saving throw becomes immune to this spell for 24 hours.
