Initiation Time: 1 action
Range: 120 feet
Duration: Concentration, up to 1 minute
Until the form ends, blinding dust and debris falls in a 20-foot-tall cylinder with a 40-foot radius centered on a point you choose within range. The area is heavily obscured, and exposed flames in the area are doused.
The ground in the area is covered with piling sand, making it difficult terrain. When a creature enters the form's area for the first time on a turn or starts its turn there, it must make a Constitution saving throw. It takes 4d10 bludgeoning damage on a failed save, or half as much damage on a successful one.
As a bonus action on your turn, you can move the storm up to 40 feet within range.
At Higher Levels. When you initiate this form at a higher level, the range of the form and the radius of the sandstorm increase by 20 feet, and the damage increases by 1d10 for each level above 4th.
