This special dust has many uses. If a pinch is cast into a cubic yard of water, the liquid is instantly transformed to nothingness, and the dust pinch becomes a marble-sized pellet, floating or resting where it was cast. If the pellet is hurled down, it breaks and releases the same volume of water. When the dust is sprinkled over an area (such as with a wave of the arm), it negates a precipitation or cloudburst spell, or else dries up as much as 15 cubic feet of water. The dust affects only water (whether fresh, salt, brackish, or alkaline), not other liquids.
If the dust is employed against a water elemental or similar creature, the creature must save vs. spell or be destroyed. A successful save still inflicts 5d6 points of damage upon the water creature.
A pouch of this dust contains 1d6+4 pinches.
