I caught Furnok cheating, then recruited him, went to Burne's Tower in Hommlet. In the Tower basement, I had my Halfling Rogue do a sneak attack. Killed him! took all his cool stuff and kept some, sold some. I did the same with Spugnoir, after he told me about the location of Emridy Meadows. Using Liv's 1.5 mod, I wonder if I missed out on something (a quest possibly?) by killing them so early in the game. Did I? if I did I could go back to my last saved game.
Ummm, I'd say, you broke it, you bought it! But according to the readme, no ur not missing anything big.
