Tarantallegra

You bring forth a magical catchy tune and a humanoid within range of your choice that can hear you suddenly feels the urge to break out in a freaky tap dance, waltz or another dance of your choice.

The target must succeed a Wisdom saving throw or start dancing for the duration. A dancing creature can't control its movement, instead it has to use its movement to move 5 feet in a random direction at the start of each of its turns, roll a d8 to determine which direction. The creature has disadvantage on dexterity saving throws while dancing. A creature without physical legs, with a flying speed or with a movement speed of 0 isn't affected.

At the end of each of its turns and each time the target takes damage the target can make another Wisdom saving throw. On a success, the spell ends and the music stops.

At higher levels. When you cast this spell using a spell slot of 2nd level or higher, you can affect one additional humanoid for each slot level above 1st. The creatures must be within 30 feet of each other when you target them. If two creatures are within 5 feet of each other when they fail their saving throws they will dance together, grabbing each other's hands or waists (if possible) and both moving in the same direction on each of their turns.
