Boogie Bomb

You point to a position within 100 feet and the crystal flies to that point. A disco ball appears in that location and loud music begins to play, creating a dance floor. Once the music begins to play, everyone within a 30 foot radius begins to dance involuntarily. Each turn, in order to take any action other than movement, each creature within the spell's area of effect must make a performance check (spell save DC) in order to do it with style.

If the user loses concentration over the duration of the spell, they lose the ability to dismiss the spell as well as the ability to cast any other concentration spells.
