Glass Storm

''A cyclone rises from the ground, whirling up sand and silt. Tiny crystal shards are separated from the particles, and they are propelled by the howling wind.''

This powerful version of the sand spray spell not only lifts and separates tiny crystal shards from sand or silt; it creates a 100 mph wind to propel them. The particles whip about the storm's area, leaving a 10-ft. diameter eye where you and your companions may stand unharmed. In addition to the effects of hurricane force winds, creatures and unattended objects take 2d8 points of damage per round until they leave the area. All unprotected flames in the spell's area are extinguished.

Note that this spell does not create the tiny shards; sand or silt must be within range for this spell to take effect.
