Dust of Sneezing and Choking
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.
