there is actually a detailed set of instructions in Ironworks BG2 page, under the CHEATS heading ... here is the link:

With no offense intended to IW, check out your readme.txt in your main Throne of Bhaal folder. You will need to change one line in your .ini file, but I have seen the line listed as either Debug Mode=1 OR Cheats = 1. (I believe the Debug Mode=1 is correct). I don't know that it DOES make a difference, or that it doesn't ... but check the readme file to see what IT says! By the way, the Debug line of text should be type exactly like:
Debug Mode=1
It IS case sensitive!!
Hope this helps.
