I'm not sure, but I think a civ valuing knowledge would produce more scholars - I'd imagine more curious personalities would also result in more scholars/writers. Tbh I think its a question only Toady would be able to answer.
Alright, I'll work on that next and return with results. While I'm at it...
What do I have to do to make a craftable weapon trap that doesn't break with use? Do I alter the material values, or the striking velocity of the trap?
The object in question was a wooden pole that is easy to dodge... right into a 10-z pit. However, if it strikes an armored foe, it slowly breaks apart. In a siege from deathlurks (heavily armored blood knights), this is a problem.
