You gain the ability to emit a noxious fog around you, causing all those around you without breathing filters or gas masks to choke and become ill.

MP Cost: 4

Benefit: Once per day, as a free action, you can produce a 20-foot-radius cloud of smoke centered on yourself. The cloud is stationary once created. The inky-black smoke obscures all vision, including darkvision, beyond 5 feet. A creature 5 feet away has one-half concealment (20% miss chance), and creatures further away have total concealment (50% miss chance, and attackers cannot use sight to locate a target). Furthermore, any living creature in this cloud must make a successful Fortitude save (DC 15) or suffer 1d4 points of temporary Constitution damage. In still conditions, the cloud persists for 10 rounds. This ability even works underwater, but a moderate wind or current disperses the cloud in 4 rounds, and a strong wind or current disperses it in 1 round.
