Smoker is a type of character that requires cigarettes to maintain happiness. The game's smokers are:
Arica, Boris, Bruno and Roman usually consume three cigarettes per day. Henrik consumes four per day. Malik, Esma and Adem consume two per day.
Ensuring a smoker has access to at least one cigarette every three days is often enough to satisfy them. However, failing to provide a smoker any cigarettes over a longer period of time results in a mood penalty. A sad smoker will make negative remarks like "Damn, where are my cigarettes?" The penalty can be avoided by scavenging for the different types of cigarettes, buying them from a Trader, or by creating them in the Shelter itself.
Smokers will consume cigarettes in the shelter overnight. A scavenging smoker will not consume any cigarettes, possibly making them go into withdrawal. Rotating smokers for scavenging duties (e.g. scavenging with Roman with one night, then Arica the next night) will help ensure every smoker gets their 'fix' regularly.
Some archetypes are less likely to become sad due to an unsatisfied addiction. For example, Boris (an altruist) is likely to shrug it off, while Roman, Emilia or Bruno (egoists) are more likely to become unhappy.
