Sandstorm
Keywords: Area (Leveled).
Full Cost: 103/130/164 points for levels 1-3.
Casting Roll: IQ.
Range: 100 yards.
Duration: Indefinite.

Create a sandstorm. Any DX-based skill checks made inside the storm, and any ranged attacks passing through the area, are at -5. Anyone within must also make an ST check each second or be knocked over by the wind. Due to the flying sand, rolls to see anything inside the storm are at -2, but rolls to notice the storm itself are at +2. Anyone within the storm must make an HT roll each second or blinded by sand for that second.

This spell requires constant concentration to maintain, but as long as you maintain it, you can also make the storm larger or smaller (up to the maximum radius based on your level). You can also designate a safe "eye" inside the windstorm up to half the radius of the storm.

This is also an Earth spell.
