Other points of interest[edit]


  1. At the east end, going to the southeast switch opens a closet to the north. Once you use the switch at the northwest part, the central lift will have risen far enough that you can go to that closet, where you can get mace spheres. (sector 23)
  2. At the northwest area, enter the lava and press on the east side of the switch at the end of the rock path to lower it. This lets you get a torch. (sector 25)
  3. At the northeast area, head north to the waterfall and go through the wall to the west to get a Tome of Power and possibly a firemace. (sector 31)
