This spell brings forth a windstorm of stinging sand that blocks all Vision. You can move the storm up to 30 feet each round as a move Action.
Any Creature in the area takes 3d6 points of piercing Damage each round. The area is considered a windstorm (see the wind effects table).
If a Creature with spell Resistance successfully resists this spell, it is unaffected by the winds and sand, but still unable to see within the area of the spell.
