Several varieties of rats exist in the maze, and this is one of the kinds that spawn there. From what I saw, they were all static spawns, and placed far enough apart to where they could all be singled, easily. They conned dark blue at level 63, hit for 2-300, slowable, did not summon. They dropped on the average 7-8 each. The maze SUCKS because it is very difficult to get out of, so I would advise staying out of the area. Comical rats...
