Dream Burst

You unleash a psychic storm from the Astral Sea through the minds and bodies of your enemies. A torrent of astral energy fills a cylinder 20ft wide and 20ft tall at a point you choose within range. Each creature within the sphere must make a Dexterity saving throw. A creature takes 4d6 force damage and 4d6 psychic damage on a failed save, or half as much on a successful one.

In addition, unsecured objects that are completely within the cylinder rise into the air and crash back down to the ground as the spell ends, potentially damaging them.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 force damage for each slot level above 3rd.
