Empty Orchestra

You summon a spectral ensemble of floating instruments that fit in a 20ft cube centered on a point within range. When you cast the spell, and as an action for its duration, you can cause the instruments to play the music you choose or stop. You can even have the music follow a creature's lead if they dance, sing, or play an instrument within 20ft of the ensemble. A creature present for the ensemble's performance for the full duration gains 2d10 temporary hit points. Each time the orchestra begins playing music, you can choose one of the options below. The effect lasts until the ensemble stops playing:

• Captivating Aura. Hostile creatures within 20ft of the ensemble that can hear it have disadvantage on saves to avoid being charmed. If a hostile creature starts its turn in this area and is charmed, it makes a Wisdom save if it can hear it. On a failure, it moves up to its speed towards the orchestra if it can and ends its turn.
• Jubilant Waltz. Friendly creatures within 20ft of the ensemble that can hear it have their speed doubled, and their movement doesn't provoke opportunity attacks.
• Sorrowful Dirge. Hostile creatures within 20ft of the ensemble that can hear it have disadvantage on saves to avoid being frightened. If a hostile creature starts its turn in this area and is frightened, it must make a Wisdom save if it can hear it. On a failure, it falls prone if it can and ends its turn.
