This small packet contains 1d6 + 4 pinches of dust. As a Utilize action, you can sprinkle a pinch of the dust over water, turning up to a 15-foot Cube of water into one marble-sized pellet, which floats or rests near where the dust was sprinkled. The pellet’s weight is negligible. A creature can take a Utilize action to smash the pellet against a hard surface, causing the pellet to shatter and release the water the dust absorbed. Doing so destroys the pellet and ends its magic.
As a Utilize action, you can sprinkle a pinch of the dust on an Elemental within 5 feet of yourself that is composed mostly of water (such as a Water Elemental or a Water Weird). Such a creature exposed to a pinch of the dust makes a DC 13 Constitution saving throw, taking 10d6 Necrotic damage on a failed save or half as much damage on a successful one.
Notes: Damage: Necrotic

Posted Mar 22, 2025This is just about my favorite magic item.
Mostly just for some of the fun math... and I kinda hate math, tbh.
1 cubic foot of water weighs 62.41lbs, so multiply that by 15³, or 3375.
62.41 × (15 × 15 × 15) = 210,633.75
200,000 pounds of water is a lot to dump into any situation.

In war time this stuff would be amazing.

Posted Mar 23, 2026My party looted some Dust of Dryness in the second level of a megadungeon. They quickly turned most of it into the marble-sized pellets and held onto them through the fourth level, when they encountered a group of Azers. They fought them once and got their butts kicked, then fled into the caves to regroup and strategize. After some planning, they returned to the Azer's forge and started smashing the pellets against the Azers' faces.
I used the details for sprinkling Dust on Elementals to rule for the damage - DC13 con save and 10d6 on a fail (or half on success) and suddenly the room filled with steam, the floors became slippery, and the tide of battle turned. It was an alright encounter that my players made pretty awesome thanks to some uncommon dust I used to fill a room two dungeon levels before!
