Crescendo

You create in a 30ft cone a wave of rhythmic energy that gets stronger with each cast. The spell can be cast up to 3 times only requiring a single spell slot to be used:

• First cast: all creatures in the affected area must make a constitution saving throw or become deafened until the end of your next turn.

• Second cast: all creatures in the affected area must make a Strength saving throw or be pushed back 10ft.

• Third cast: all creatures in the affected area must make a constitution saving throw or take 3d8 thunder damage on a failed save or half as much damage on a successful one.

The spell ends after the third cast or earlier if your concentration is broken.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
