Respiratory Distress

This potion reacts instantly with air, rapidly expanding into a 15-foot-radius cloud of irritating gas when exposed. You can throw it at a point you can see within 60 feet of you, causing it to break open and release the cloud there. Each creature within the cloud when it appears must make a DC 15 Constitution saving throw. On a failed save, a creature spends its reaction coughing and snorting and its concentration is broken if it was concentrating.
