Ætherstorm

A sphere of astral energy rips through a space centered on a point within range. All creatures within a 25 foot-radius sphere must make a Con Save. On a failure, creatures are pulled 15 ft towards the center and take 6d8 force damage.

If a creature is at the center, or the center is occupied by a creature so that another cannot occupy the space, all such creatures take an additional 2d6 bludgeoning damage and are knocked prone on a failure. On a success, creatures take half damage.

For each level this spell is cast beyond the 4th, this spell deals an additional 1d8 force damage
