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. When the storm appears, each creature within its area takes 8d4 force damage. When a creature moves into or through the storm, it takes 2d4 force damage for every 5 feet it travels, and whenever a creature ends its turn in the storm it takes an additional 8d4 force damage.

On each subsequent turn for the duration of the spell as a bonus action, you can move the storm 15 feet in any direction and cause it to fling forth a hail of force bolts that seek out up to 3 targets of your choice within 15 feet of the storm. Each creature targeted takes 3d4 + 3 force damage from the force bolts.

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