The Music Dance Experience

As you cast this spell, jaunty music begins to play as you perform a jolly, lighthearted dance, creating a 20ft emanation around yourself. While dancing in this way, your speed is halved. All creatures within this emanation must make a wisdom saving throw or become charmed while within the area. While charmed, the target joins you in dancing and must use all of their movement to dance around you and do its best to stay within the emanation if you move. While dancing, it has disadvantage on dexterity saving throw and attack rolls, and other creatures have advantage on attack rolls made against it. On the end of each of its turns, the target can take an action to collect itself and repeat the saving throw, ending the spell on itself on a success. If you ever stop dancing during this time, the emanation dissipates, and the effect immediately ends. However, resuming your dance while the spell is still active, causes the emanation to reappear.
