[Micah]

I don't think there's a threshold number before craziness happens, the number just influences the probablity of it occuring (and if you haven't had a crazy commander before it's a turn-to-turn effect, not somethng that will happen every turn once it happens once). The crazy actions tend to be useless, but won't cause the commander to attack or burn gems, as Shovah said. I'm pretty sure even sneaking crazies are safe, but I'm not 100% on that. My rlyeh dominion-induced craziness had my friend's commanders performing a "heretic preaching" action sometimes that might have hurt his dominion some, as well as one action that was called "that's not a star." No idea what that one did. My insane rlyeh commanders all took semi-normal actions. Semi because non-mages and non-prests would still preach, research, or site search, plus the prophet option. I'm not sure on how many brands of crazy the game has in total, but at least two it seems.
