Chaos Storm

Until the spell ends, chaotic energy rages in a 20-foot-tall cylinder with a 40-foot radius centered on a point you choose within range. The area is heavily obscured.

The area feels heavy, making it difficult terrain. When a creature enters the spell's area for the first time on a turn or starts its turn there, it must make a Dexterity saving throw. On a failed save, it falls prone.

If a creature ends its turn in the spell's area it takes 4d10 psychic damage.

If a creature starts its turn in the spell's area and is concentrating on a spell, the creature must make a successful Constitution saving throw against your spell save DC or lose concentration.
