Jaccus Maxxen's Dungeon

Deep under Rathleton, the mad Professor Maxxen hides in his laboratory. Visitors must walk through several rooms and face many different creatures before reaching the laboratory, though. In the dungeon, there are 4 large rooms filled with creatures that can be used as hunting places, as well as some smaller rooms which are part of a quest. 
Each room as a different combination of Oramond creatures, Lost Dwarves and some other creatures, which may require slightly different strategies to efficiently hunt in each one of them, however, a Dwarven Ring is essential for the first three rooms, even if you're just running by them.
