Dust of Dryness was a magical powder created through Alchemy and prized by explorers, sailors, and Artificers alike. Stored in small packets containing several pinches of fine gray dust, it possessed the remarkable ability to absorb vast quantities of water. A single pinch reduced a volume of water roughly fifteen feet on a side into a tiny marble-sized pellet. These weightless pellets could be carried with ease and later shattered to release their contents in an instant.
The dust proved useful for transporting water, crossing flooded passages, or clearing submerged chambers. Its power extended beyond mundane applications, however. Creatures composed primarily of water found the substance particularly dangerous, as contact with even a small amount could drain their essence and inflict severe harm. For this reason, Dust of Dryness was often carried by Adventurers expecting to face Water Elementals or other aquatic threats.
