Arcane Maelstrom

You summon a chaotic storm of arcane energy that wreaks havoc on the battlefield. A swirling vortex of magical power appears at a point you choose within range. The vortex has a 20-foot radius and extends up to 60 feet high.

When you cast this spell and at the start of each of your turns while concentrating on it, the vortex unleashes a violent storm of arcane energy. Each creature within 20 feet of the vortex, including you, must make a Dexterity saving throw. On a failed save, a creature takes 6d10 force damage and is pushed 10 feet away from the vortex. On a successful save, the creature takes half damage and isn't pushed.

Any creature that ends its turn within 20 feet of the vortex must also make a Dexterity saving throw, taking 4d10 force damage on a failed save or half as much on a successful one. This damage is in addition to the initial damage from entering the vortex's range.

Additionally, the vortex creates difficult terrain within its area. Any creature that enters or starts its turn in the vortex's area must make a Strength saving throw or be pushed 10 feet in a random direction by the swirling arcane winds.

At Higher Levels: When you cast this spell using a spell slot of 6th level or higher, the initial and recurring damage increases by 1d10 for each slot level above 5th.
