Other points of interest[edit]


  1. Lower the wall behind your starting point to find a Mystic Urn. (sector 32)
  2. In the staircase at the southwest end of the first area, flip the switch at the bottom and watch the walls around you lower. When they lower all the way, you will find an Undead warrior ghost guarding Gauntlets of the Necromancer. (sector 158)
  3. In the blue key room, press on the wall east of the southeast column to find a Morph Ovum. (sector 211)
  4. Open the blue bars, but do not enter the teleporter yet. Press on the wall to the south and the next wall to find a Shadowsphere. (sector 96)
  5. Enter the teleporter mentioned in Secret #4 to reach the second half of the map, then open the wall to the south, similar to what you did for Secret #4. This time you will find a Chaos Device. (sector 418)
  6. In the second area, go all the way to the door at the west end and use it. The door will not open, but a part of the wall to the north lowers instead. Quickly go over it and to the left, where the Enchanted Shield is. The wall should rise up, allowing you to get the enchanted shield. (sector 462)
  7. In the last arena, the column in the middle has a switch on the left side. Flip it, then run straight west through the vines to find a Phoenix Rod. (sector 471)


When you press the switch to lower the blue key, you will also allow enemies in a teleport closet to teleport into the map, landing on the pad in the middle of the southern part of the first area. However, the landing destination is only flagged for thou art a smite-meister or higher, meaning two Golems and up to eight Gargoyles will not teleport into the map.
