Dust of Sneezing and Choking

This fine gray dust is usually found in a vial and appears to be dust of disappearance , even when magic is used to identify it. Each vial contains enough for a single use.

You can use an action to throw the dust into the air. You and creatures within 30 feet of you that breathe make a DC 15 Constitution saving throw or become wracked with violent coughing and sneezing, becoming incapacitated and beginning to suffocate . While conscious, a creature can repeat the saving throw at the end of each of its turns, ending the effects on a success. A lesser restoration spell also ends the effects.
