This was the 8th manual in my library I have for running my NWN module and it is the worst one so far. I really didn't find it as useful as I though it would be. I needed it for the 3rd edition gods and really, it doesn't give me any more info then the 3 primary books (DM, Players, Monster). In fact, It seems to contradict them a bit. I shouldn't of purchased this book, it really will just rot a bit. For a module designer who's trying to add deities in to their NWN module, its really not worth it.
