Known Traps

Trap DCs

  • Force traps across bridge; the control panel is on the far (east) side of the bridge, on the north.

Tips and Misc

  • As previously, no shrines.
  • The two cells are locked again, unpickable and with no key; however, the door to the east is now open.
    • Trivia: The "kalashtar" mentioned as you head down this tunnel are a race of psionics in Eberron, descended from a group of human monks who allowed themselves to be possessed by good-aligned Quori.
  • After the open door, the northern hallway leads to a pit with rust monsters and a chest.
    • Optional: Corrosion may appear in the rust monster pit; if so, the other rust monsters won't be there – however, they'll spawn if you open the chest afterward.
  • The Key to Grust's Lair is held by an ogre shaman at the top of the two ladders, right in front of the door.
    • Optional: Chef Grank may appear in the first (unlocked) room to the south after acquiring the key.
  • The trollish allies are in the last two rooms before Grust's room; the doors are locked at first, but will unlock when you cross the threshold into his room, even if sneaking.
    • Optional: Champion Preinyl, and his chest, spawns in the southern locked room at the end when you fight Grust. He can count for one of the two trolls which you need to slay. For him to appear, you must allow the door to close after the Deathblood Troll inside leaves the room and then re-enter the room yourself – a troll opening the door from outside (if you ran inside before the door closed) does not cause this.
