Rod of Rulership

Once per dawn, while holding this rod you can use an action to command obedience. Each creature of your choice that you can see within 120 feet makes a DC 15 Wisdom saving throw . On a failure, a creature is charmed by you for 8 hours. A creature charmed by you regards you as its trusted leader. The charm is broken if you or your companions either command a charmed creature to do something contrary to its nature, or cause the creature harm.
