Aether Storm

You conjure a storm of aether erupting from a point of your choice within range. The aether storm fills a 10-foot radius, 40-foot-high cylinder centered on a point. When the storm appears, each creature within its area takes 8d4 force damage.

A creature takes 1d4 force damage for each 5 feet they move through the storm, and if a creature ends their turn within the aether storm, they take 8d4 force damage. On your turn, you can move the storm 10 feet in any direction as a bonus action.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d4 for each slot level above 5th.
