OK, I take that as an abstraction, then.
If we were going for the real thing then smoke inhalation should also have a chance of lowering your max INT to simulate brain damage if asphyxiated for several minutes. Now, let’s imagine all the real effects of smoke were implemented, for the sake of it. Here’s an extract from that link:
“Inhaling carbon monoxide decreases the body’s oxygen supply. This can cause headaches, reduce alertness, and aggravate a heart condition known as angina. Fine particles are able to travel deeply into the respiratory tract, reaching the lungs. Inhaling fine particles can cause a variety of health effects, including respiratory irritation and shortness of breath, and can worsen medical conditions such as asthma and heart disease. During increased physical exertion, cardiovascular effects can be worsened by exposure to carbon monoxide and particulate matter. Once exposure stops, symptoms from inhaling carbon monoxide or fine particles generally diminish, but may last for a couple of days.”
In game terms that would mean:
- Pain (headaches)
- -PER (reduced alertness)
- -movement points/speed (shortness of breath)
- even more severe penalties for characters with asthmatic trait
Duration: 1-48 hours
Some of those (-speed) are already implemented (see smoke field and smoke disease), while others are added to simulate lower combat abilities in that state, I guess (-STR -DEX). Apart from the coughing, that is, which creates a lot of noise
If only half of this was implemented, smoker zombies would suddenly go up there with hulks.
