IIRC, no XP in the Breeding Zone, either. IMO, it's because both Walls of Mists and Breeding Zone reset every time you enter them. If you got XP, both these dungeons would become efficient and bottomless sources of XP. This contradicts the spirit of the game.As far as items are considered, Breeding Zone contains only the Book of Divine Intervention. Creatures in Breeding Zone drop nothing. Walls of Mist is an efficient source of money and stat points (8 barrels behind the central portal). Creatures in Walls of Mists usually drop nothing special, although it has been reported that they can drop even artifacts.
