And first - Killing Diablo in normal hell should be very easy, with any class, even with most heavily restricted variants. All you need is determination and a little know how. There is a lot of information inside the back pages of this forum, or go to RBD, Realms Beyond Diablo, it should give you a good start. http://realmsbeyond.net/diablo/cd.html
Good luck on your first kill :)

Anyone happen to have Jarulf's Guide version 1.20? Or happen to know around what time it was written, which Diablo version would it correspond to?
