Elemental Maelstrom

The caster creates a swirling tornado of elemental magic (caster's choice) centered on themself. The tornado is 10ft in diameter, and 20ft tall. Unless they choose to move the tornado, the caster stands in the eye of the tornado. The tornado can be moved in one direction of the caster's choice, and will keep moving in this direction until the spell ends.

If a creature (aside from the caster) comes into contact with the walls of the tornado, it must make a dexterity save. It takes 2d8 elemental damage (caster's choice) on a failed save, and half as much on a success. The spell ends if it is dispelled or if concentration is broken.

The damage dealt by the spell increases by 1d8 for every spell slot level above 2nd.
