Blade Squall

You conjure a 10ft radius cyclone of whirling, razor-sharp blades made from energy of Elemental Wind. The cyclone appears within range and lasts for the duration. You can use you action to move the cyclone up to 40ft in any direction, or your bonus action to move the cyclone up to 20ft in any direction.

When a creature enters the cyclone's area for the first time on a turn or starts its turn there, the creature must make a Dexterity saving throw. On a failed save, the creature takes 4d10 slashing damage. On a successful save, the creature takes half as much damage.

At Higher Levels: When you cast this spell with a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4th.
