I've found HELP AFFLICTIONS shows what the afflictions are called and what cures them, and AFFLICTION SHOW <whatever> gives you the messages for the affliction. Some of them are very intuitive (asthma won't let you smoke) but others aren't. I'm trying to figure out what a lot of these do. Is there a HELP scroll or a wiki or some kind of resource that details the actual effects of some of them? Stupidity, Amnesia, Clumsiness, Concussion come to mind, where I'm not sure I have any clue about what their effects are.
