Use the key Bob found downstairs and head into the hallway. You should probably kill the rest of the zombies in the blue tile room while invisible, since Bob needs to re-cast Reveal Invisible at level 5 dominant to find the hidden door. If not, have Bob become invisible or set up a Damage Field where the narrow hall opens into this dead end room. If Bob is still invisible, go ahead and survey the room then leave. Head into the fourth survey room to Bob's immediate right (screen left).
Head back out, re-cast invisibility and go up the ladder to the room where Pious found the Granite Block (blue). Re-cast invisibility to deal with the monsters in the Four Sigil Room, then take a walk around to build the magick to cast a dominant level 5 Reveal Invisibility to get the Forgotten Corridor Key. Shoot the two Trappers and cast a dominant level 3 Reveal Invisible to find the Sapphire Effigy in an alcove in the side of the hallway. Head down the ladder and into the T-shaped hallway outside of the Four Sigil Room. Open the only door Bob hasn't gone through and wind up in the room where Pious picked up the Grantite Block (blue). Head back to the trap room and save the game. Bob will pick up the Artifact of Dark God and the Ruby Effigy (if Karim found it before). Run, walk, or scrape past the Dark Guardian and its buddies to the third survey room. Save the game and re-cast invisibility before going down the ladder. Run past the Horrors fighting in the next tunnel and into the next room where you can catch a trap in progress.Ĭast the Summon Zombie spell and move your new buddy onto the floor plate to open the gate. Pick up the "Summon Zombie" scroll and head down the ladder. Save the game if you want and prepare for the Trappers in the tunnel below the second survey room.Ĭast Invisibility before Bob heads up the ladder to a coloured mist tinged room with a Dark Guardian. Climb the ladder to the second survey room and pick up the Tome of Darkness when Bob leaves by the other ladder. Pull all three levers in the cage tunnel to open the way forward. You do not have to fight the zombies in the next tunnel, but the saif will make short work of them if you do. Save the game and head down the ladder on the other side.
While Bob's here in the second big room, pick up the Saif and crossbow ammo. Once the survey is done, the "X" on that room will disappear from the map. To survey a room, head to where the dirt constantly falls from the ceiling and inspect the spot. Run past the zombie and up the ladder again to the first survey room.
Equip the torch, head down the tunnel and head up the ladder to a large room. If he doesn't survey all the rooms, he can't leave.
