Blight Storm

Creates a Blight Storm within range with a radius up to 20ft and a height up to 40ft. Targets that are caught in the storm must make a Strength saving throw or suffer 2d10 bludgeoning damage plus an additional 1d10 damage per spell level beyond 1st  and be carried by the storm. Targets take half damage and stay rooted on a successful save.

Upon exiting the Blight Storm, targets sustain 1d12 + your spell casting modifier acid damage every round for 3 rounds.

The caster may use part of their movement to make the storm move a distance up to their walking speed, but cannot use the Dash action to make the storm move further.
