Right now, I'm going through Avernum 1 for the first time (I just got the trilogy a couple weeks ago), and I keep getting owned by mung demons and basilisks. Is there a potion or some item that will prevent dumbfoundedness or cast Unshackle Mind? And, where do you find more crystal gear? I just found one crystal shield in the Great Cave, and haven't run into any more. In addition, that shopkeeper in Fomello who's supposed to sell a crystal necklace (Sue, I believe) doesn't seem to have them.
But, aside from this, I love this game. I bought this, and I bought Bioshock about a week later, and I've been playing Avernum way more than Bioshock.
