Method

• Starting off in Ab'Dendriel, find the Shadow Caves (north-west the depot underground, here).
• Go down 2 more floors and follow the cave south and then east. You should find a (normally locked) door, the Hellgate entrance. Open the door with Key 3012 and go in (if you don't have key 3012 you can buy one from Elathriel, the nearby prison guard, for 5000gp).
• Enter the northern teleport to enter Hellgate.
• Follow the images below to reach Draconia. You may encounter Skeletons, Spiders, Poison Spiders, Ghouls, Rotworms, Carrion Worms, Rotworm Queen (rarely), Slimes, Bonelords, and Demon Skeletons. It is possible to encounter some lured Elder Bonelords as well. Encountering anything else is a sign that you took a wrong turn.
• The map does not direct you to the surface, it will end at Redbone Castle. However, the path beyond the map is one-way so you cannot be misguided.

Ground Floor[]

This floor (inside the pyramid) has many skeletons and scorpions.

• Key 3001: from the hole, walk to the north-west side of the pyramid. Open the skeleton corpses to find Key 3001. You may have to move a few corpses before you find the right skeleton corpse.
• Key 3002: return to the hole you came from and walk south. Open the eastern door with key 3001 and walk north to find a red carpet. Walk along the south row of the carpet. Carpet tiles will burn and electrify you - and 2 tiles are hidden holes which drop down to 10 scorpions. On the other side of the carpet, open the second coffin on the north side of the room to find Key 3002.
• Key 3003: go back to key 3001's location and walk south, to the south-west part of the pyramid. Open the door with key 3002 and pull the lever. Go north again and pull another lever (the lever destroyed a wall blocking its access). Again go south where the rock will have disappeared. Pick up Key 3003.
• Now go back around and use key 3003 on the western door in the south-east corner of the pyramid. Follow through to the staircase.

Search the skeleton corpses for Key 3001. You may have to remove a few corpses before you find the key.

Walk along the red carpet - watch out for the holes (they appear only once you fall through them).

Open the coffin to find Key 3002.

Pull the lever to destroy the wall north.

Pull the lever behind the (now destroyed) wall to destroy the stone.

Go back and pick up Key 3003

Second Floor[]

Here you will find skeletons and ghouls.

• Key 3004: from the staircase, go south and east. You will see a room filled with Energy Fields. Use Destroy Field or Browse Field on the tile in the first row, third column. Key 3004 will be revealed.
• Key 3005: from key 3004's location, go south. Open the door south with key 3004, inside the room go west and follow the path to find Key 3005 laying on the ground next to the statues.
• Key 3006: go back to the stairs you came from, and this time go west. Open the door with key 3005 and you will find another room with fields in it - this time fire with some energy. Use a destroy field rune or Browse Field on the south-easternmost tile to reveal Key 3006. Pick it up.
• Go back to the south and enter the final locked door using key 3006. Go up the ladder.

Key 3004 is found under an energy field on the top row, third column.

Key 3005 is found on the ground in the south-west room. You need key 3004 to get here.

Key 3006 is found under a fire field in the north-west room. You need key 3005 to get here.

Third Floor[]

This floor has 6-8 ghouls and 2 demon skeletons. This is the part you need at least 2 people. This spoiler will assume the minimum of 2 people, although 3 players can do this each having a unique purpose.

• Key 3007: from the stairs, follow the path until you find two floor switches. Leave player 1 on the southern switch. Player 2 must now go west, enter the south-western room and step on the floor switch in there. Player 1 must then leave his stand, go west and then north to enter the portal and take Key 3007.
• Player 1 must now go back to the floor switch they stood on before. Player 2 may then leave the room.
• Both players now go upstairs.

Player 1 stands here. The south-west room will open.
