Ætherstorm

A sphere of astral energy rips through at a space centered on a point within range. All creatures within a 25 foot-radius sphere must make a Constitution saving throw. On a failure, creatures are pulled 15 feet 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, and are not knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, it deals an additional 1d8 force damage for every level above 4th.
