As a bonus action you can sing an aluring song. All creatures within 30 feet of you that can hear you must make a wisdom save (DC is 8 + your Charisma modifier + your proficiency bonus) or be charmed by you. A creature charmed in this way will obey commands issued by you to the best of it's ability. If the charmed creature takes damage, it may attempt the save again. This charm lasts for a number of minutes equal to your Charisma modifier minimum of 1. You may use this a number of times equal to your proficiency bonus.
