Found in a small container, this powder resembles very fine sand. It appears to be dust of disappearance, and an identify spell reveals it to be such. There is enough of it for one use.

When you use an action to throw a handful of the dust into the air, you and each creature that needs to breathe within 30 feet of you must succeed on a DC 15 Constitution saving throw or become unable to breathe while sneezing uncontrollably. A creature affected in this way is incapacitated and suffocating. As long as it is conscious, a creature can repeat the saving throw at the end of each of its turns, ending the effect on it on a success. The lesser restoration spell can also end the effect on a creature.

As a Utilize action, you can throw the dust into the air, forcing yourself and every creature in a 30-foot Emanation [Area of Effect] originating from you to make a DC 15 Constitution saving throw. Constructs, Elementals, Oozes, Plants, and Undead succeed on the save automatically.

On a failed save, a creature begins sneezing uncontrollably; it has the Incapacitated condition and is suffocating. The creature repeats the save at the end of each of its turns, ending the effect on itself on a success. The effect also ends on any creature targeted by a Lesser Restoration spell.
