You cause a humanoid you can see within range to make a Wisdom saving throw. If you or any creature friendly to you have entered combat within a 24-hour period, it has advantage on the save. On a failed save, the target becomes charmed by you, treating you and any creature friendly to you as friendly, which lasts for the duration or until you or any creature friendly to you enters combat against it. Once the effects of this spell ends, the target knows it has been charmed by you.
Upcasting: You can choose an additional target for each spell slot level above 1.
