Admitedly, I haven't played Arcanum in a while, but something just occured to me: Correct me if I'm mistaken, but I don't re-call dialogue options ever being different when you're drunk!! Am I wrong and/or has anybody else noticed this!?
Being drunk decreases your intelligence, so when you get drunk enough to have trhe stupid dialogue options, you speak like stupid.
It decreases with every bottle, the more you drink, the more drunk you get. I don't remember if there's a limit of decreases in one shot.
It wears off with time. It's pretty neat, but if I could do anything to improve it? Alcohol poisoning. First time, you get knocked out, and suffer permanent constitution damage. Second time, you die. It's been a while since I've actually drank anything in the game, I don't remember if it gives temporary bonuses to anything.
Re: drunk did I miss something Try getting blind drunk at Madam Lil's. There should be some dialog options there. I think a couple were broken though. Did I post a fix, elsewhere?
It counts the drinks you take, but I think there's another error that could let him give you another one when your stat is on 1.
I mentioned it at the end of "Make them Moan: Lover's Quest" http://terra-arcanum.com/phpBB/viewtopic.php?t=14077
