Spun Cloud (Green)

On the Elemental Plane of Air, small clouds of differing colors can sometimes float separately from other cloud formations. Clever people can spin these clouds into small handfuls, creating a magical bundle of elemental power. Unlike most bottled breath, spun clouds don't have any effect on you while you hold them in your lungs, but you can exhale the cloud as a single action. When exhaled, the cloud flows out and expands into a 20-foot burst within 60 feet of you. The cloud dissipates after 1 minute.

A green cloud smells terrible, making those inside ill. Any creature that ends its turn in the cloud must succeed at a DC 25 Fortitude save or be sickened 1 (or sickened 2 on a critical failure). Regardless of the result of its save, the creature becomes temporarily immune for 24 hours. This is an Olfactory Poison effect.
