Tips and Misc

  • In the room with the collapsing floor and the seven "bait" chests, the chests are NOT real, so you don't have to waste a lot of time and jumping to try and get to them (it IS possible by jumping onto the ledges on either side of the room but it is pointless).
  • Note: Bring deathward/deathblock items as the cave beholder now must be slain to complete the quest. Be sure to kill it along the way as it will be a long run back from the end if you forgot to do so. It can be found in the long dead-end extending south from the cavern tunnels. (Start by going south from the entry point, just follow that tunnel south, you'll come right to it.)
  • Knock/Open lock recommended but not required. There are two locked doors which must be opened to proceed. The silver key to the first door will be in a chest which is randomly placed somewhere in the dungeon - if you're lucky you will find it along the way to the end. If not check the map for other possible locations. The 2nd one - the jeweled key can be found in a chest just past the secret door, guarded by ice flensers. Neither are required if you can knock or lock-pick the doors.
  • Note this quest has been heavily nerfed over the years and no longer features any shrines, loot, or optionals, so try to be efficient and stick to the main path as it can be quite long if you get lost.
