This spell requires the caster to be in open air. If the spell is cast in an area where the caster cannot see the sky, i.e. underground, the spell automatically fails. The caster temporarily takes control of the weather and creates a thunderstorm. If there is already a storm, it gets worse, otherwise a storm appears instantaneously after the spell is cast.

One round after the storm is created (or instantly if a storm is already present), the storm spawns a tornado on an area within range that the caster chooses. Any creature within 30ft of the tornado must succeed on a dexterity saving throw or take 8d6 slashing damage from the debris, half damage on a save. Light structures, e.g. hay, thatch, thin wood, automatically fail this saving throw and take 8d6 slashing damage.

Creatures of large size or smaller within 10ft of the tornado must also roll a strength saving throw to avoid being picked up and thrown by the tornado. On a successful save the creature remains in its space. On a failed saving throw, the creature also takes 4d4 bludgeoning damage and is thrown 50 feet from the center of the tornado. Structures that have been collapsed by the tornado can also be picked up and thrown.

As a bonus action the caster can move the tornado at a speed of 20 feet.

Any creatures that start their round in the raging wind must continue to make saves until they are clear of the thrashing winds.

After the duration ends, or conentration is lost, the tornado remains for 1d6 rounds and moves in a random manner before dissipating.


Higher Levels: If cast as a 9th level spell, the tornado increases its intensity, dealing an additional 6d6 slashing damage from debris, and creatures of size Huge or smaller being affected by winds. Tiny and small creatures automatically fail this save. The caster also maintains control until the spell ends, unless concentration is broken.
