Thirsty sand

Thirsty sand was a magical sand originating in Zakhara, the Land of Fate, that possessed magical properties similar to dust of dryness.

Powers
Thirsty sand drained water from nearby living creatures. This sand caused excruciating pain from massive dehydration to a single target. The sand would fall into clumps around the victim's feet after draining water from them. Additional handfuls of this sand could be thrown at the same target, causing even more harm. A full gallon of water needed to be consumed to replenish the water stolen by the sand.

Thirsty sand was especially deadly to any water-based creatures.
