This game WBC3 has a lot of content that could fill a lot of pages in a manual(s) It came only with a very brief one that leaves out a lot of information. There was also supposed to be a separate manual describing spells. GOG didn't include it. Does anyone else have this problem? I would like a bestiary at least.
