Stormcrow, you don't need to worry about Dez. She's got Greater Blink and can just slip through the walls or floor. Plus, you carrying her will just make it more difficult for her to cast any spells. She's not prone and helpless the way Rezzik is, and Dez was probably going to (try to) fix that fairly soon. Now, if there were some way for any of us to banish the spider, that might be quite useful (assuming anyone is capable of doing so).
