This level may be rather confusing to navigate as the two central large chambers and the corridors attached to them look quite similar. The chamber you start in has some water spilling from the central column, its twin doesn't. Check the automap if you start feeling lost.
Go ahead and collect the brass key first; from the starting chamber, take the more northerly of the western doors and head down the hall to the room where you'll find it.
From there, you can head over to the eastern side of the map and enter the pentagram chamber. When the coast is clear, head up the spiral stairs and claim your prize. Don't panic if you get locked in and the pull chain has been used up, just climb the stairs again and the door should re-trigger. Now, if you didn't carry over a flight spell from a previous level, head back to the northern water chamber and pull the chain by the northern doors to open them. Get the spell, you'll need it.
Explore the area if you wish, then make your way back south to the lava chasm in the south-central area. The black key is hidden down there, but the pit is too deep to get out of, so fly or die.
Now that you've got the pentagram and the black key, you can head to the exit chamber at the west end of the map. Bash the Midian Warriors who are waiting for you and get out of here.
Tips and secrets:
- The small passage to the extreme north, near the large swinging doors, drops down to a hoard of silver, but beware that you may need a flight spell to get back out.
- Once the stained glass windows are broken, you can jump through them to quickly get to the adjacent rooms.
- In the hallways to the east and west of the water chambers, jump up and explore the areas with the red barbarian face walls. Not only do they contain treasure, some of them connect the hallways to each other.
- Between the two big sets of swinging wooden doors in the west, you can find an Open Doors spell and a bunch of gold.
- Don't miss the weapon enchantment shrine in the southwest region of the map.
