Cascading Winds

You create an incredibly forceful wind in a 60ft cone in front of you. 

All creatures within the cone must make a Strength saving throw taking 8d8 bludgeoning damage and are knocked prone.

Creatures take half damage on a successful save and are not knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
