Humperdink's Halitosis (TP)

You belch forward acidic fumes, afflicting those in a 15-foot cone before you. The fumes spread around corners. All creatures in the area must make a Constitution saving throw, taking 3d4 acid damage on a failure or half as much damage on a success. The fumes linger until the end of your next turn or until dispersed by a moderate or stronger wind. Any creature ending its turn in the area must make a Constitution saving throw, taking 3d4 acid damage or half as much damage on a success.

At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, the damage (both initial and later) increases by 1d4 for each slot level above 1st.
