I was super happy to have my drow character turn on a dime and instant-loyalty in true jaluk fashion when a female drow priestess told him to turn around and stab his buddies. He did. No questions asked. And then, of course, he turned right back around and killed HER, for turning her back on Lolth. Aaaah, that was a fun murderhobo campaign. I think I killed pretty much everything on the map before moving to live in the underdark area.
