You attempt to charm a creature that you can see within range. To be affected by this spell, the target must be able to understand at least one language, though it need not be a language you speak. The target must make a WIS save and does so with advantage if you or your companions are fighting it. On a failed save, it is charmed by you until the spell ends or until you or your companions do anything harmful to it. The charmed creature regards you as a friendly acquaintance. When the spell ends, the creature knows it was charmed by you.
