You attempt to charm a humanoid you can see within range. It makes a Wisdom saving throw, with advantage if you or your companions are fighting it or threatening it. If the saving throw fails, the humanoid remains charmed until the spell’s duration expires, until you or any of your companions do anything harmful to it, or until a full moon rises in the sky. The charmed creature regards you as a friendly acquaintance. When the spell ends, the creature knows it was charmed by you.
