Deadly Waltz

You perform a short waltz. As it ends, you extend your arm towards your target and the creature is surrounded by a ring of purple flame. The creature must make a Constitution saving throw; if it is currently Charmed, they must roll instead with a disadvantage. It takes 2d8 fire damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
