Have plenty of "weaken non-material beings" spells ready, because this is one tough level. When you first enter this level, you'll pass over a trap door, which opens after you pass over it. Simply take one more step forward to reclose it and you'll hear a click indicating that it has closed. Always keep it closed for a path of hasty retreat back up the stairs. You'll figure out how to keep the trapdoor so it'll close when you need it to. There're fireballs being "shot" and they are hitting these teleport areas which are deflecting them all over the place. So if you see fireballs go skimming past your nose, don't worry, they are just being reflected off a teleport area. So stay out of their line of travel.

You should shut off the fireballs, so from the stairs, turn left and start going forward, depending on where you are standing. If you take four steps and run into a wall, then move left and continue forward about (exactly?) 13 steps. Then start going left about 7 steps. You find a dead end hallway where the fireballs are being shot out of. Near the first that the fireballs are shot into is a switch that will turn the fireballs off. So hit it or else the fireballs will continue to be shot out, one every 30 seconds.

Next after turning off the switch and still facing the wall, turn around 180 degrees and go forward four steps. Turn left and keep going until you hit a wall. Then back up a few paces and search for a switch which opens a secret door in the area that contains a powerful staff. Now return to where that switch was and move back the way you came about 6 paces and then turn right and go about 4 - 5 paces and look for a key on the ground here. You need this later. Make it back to the stairs. Now from the stairs, first turn right and you'll see a teleport field. Walk towards it and enter it and it'll turn you in the direction of the next teleport field in sequence.

Go to second field and it turns you again. Go forward and go around the open pit. Keep following the!fields. Go past number three and find the fourth field. Search the area for a button and press it and!you've opened a passageway. Go to the long hallway area. You'll start walking down the long hallway and you'll notice you seem to be walking forever? Huh? Well here's what you do. At the very beginning of the hall, move 26 paces down the corridor, then stop. Turn around and wait a couple of seconds and you should then see a door open. If you overstep your mark, it automatically teleports you back to the beginning.

Now find your way back to the beginning stairs. Since the open space is large it's too hard to tell you where certain things are. From the stairs, turn left and go about 11 steps forward avoiding the pits. Turn left and go straight, you should find a hallway with a door. Use the key that you found earlier to open it.

From here you should be able to make it down the stairs pretty easily. Ensure you've got plenty of food and water as more becomes pretty scarce from here on out (if you run completely out of food like Rom Chip did towards the end, just make bunches of Stamina potions, which seem to do what food does). You can run back up to the level where you can kill gobs of screamers and worms if you want to and stock up on food and then return as Rom Chip did.
