Arrow of Nymphsong

You brandish the weapon used to cast the spell, sing a short love ballad to Sune, and conjure spectral weapons (or ammunition appropriate to the weapon) that launch forward and then disappear. Each creature of your choice that you can see in a 60-foot Cone must make a Wisdom saving throw. On a successful save, the target dances seductively until the end of your next turn, during which it must spend all its movement to dance in place, and other creatures have Advantage on attack rolls against it.
