Pollution Cloud

Arikam Pathfinder RPG Stat Block:

Pollution Cloud

Moving slowly against the breeze, the smoke cloud billows towards you, the wretched stench of its noxious fumes preceding it, a smell that reminds you at once of all the grime of the city.

Gaseous (Ex) A pollution cloud has a body composed of supernatural smoke. It can pass through small holes or narrow openings, even mere cracks, but cannot enter water or other liquid. It has no Strength score, and cannot manipulate objects as a result.
Vulnerable to Wind (Ex) A pollution cloud is treated as a Tiny creature for the purposes of determining the effects high wind has upon it.

When a pollution cloud becomes an animate living thing, it seeks out small crevices to occupy and spread its toxic vapors. At first this means that the nooks and crannies of the cities where they emerge become the place where it lairs, filling in through small gaps in poorly-ventilated windows and down chimneys. However, the gas also willingly visits the insides of people’s lungs just as easily, leading to sickness and eventual death in its caustic corrosion. It does this not out of any active malice, and simple because of its nature.
A pollution cloud forms when large quantities of smoke are habitually created on an industrial scale in an area where magic is involved. Neither a single common tobacco cigarette nor an entire city of smoking chimneys will create a pollution cloud on its own: the smoke must be created in great amounts, but only the presence of some supernatural or spell-like effect working continuously will result in its creation. Unfortunately, with wide-spread reliance on the use of enthusiastic fire elementals in various industries that rely on steam-powered engines, the emergence of pollution clouds is becoming more common. Though it is possible for one source of smoke, such as a train, to create a pollution cloud, it can take many years to do so, while magically-powered factory districts in dense urban areas are almost guaranteed to create one eventually. Most rural areas are safe from pollution clouds, but alchemist and wizard experts on oozes catalog that one occurs in any given major city at least once every year. An infestation of multiple stacks of pollution clouds hanging around an area is both a sign of heavy industry and a complete lack of sanitation standards on the part of civil leadership.
A pollution cloud, being gaseous, weighs less than a pound but can reach 30 feet high.
