Disco Inferno

You unleash a burst of magical energy that encourages a lively performance. Choose one creature within range. If that creature engages in a creative performance such as singing, dancing, painting, or prancing, they can deal 1d6 fire damage to a target of their choice within 60 feet for each round of successful performance. The target must make a Dexterity saving throw, taking half damage on a success.

When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
