level 3 just to the left of the teleporting puzzle most players are getting stuck on. Once you are passed the teleporting puzzle return to the plate you used to make it past the previous puzzle. If you remove the item right in front of you another plate will flip up allowing you to cross. Once across the previously inaccessible area, there's the Iron door on your left and a portcullis on your right. In visible range, there's a pit right behind the portcullis, a torch and a level beyond the pit. I cannot figure out how to get back there. Has anyone had any luck with this puzzle? I have not seen it brought up yet.

In a room to the east of the iron door, you'll see a puzzle similar to the first puzzle on this floor, dealing with the three torches being placed on the center pillar. Place the torches on the opposing sides, and leave no torches on the middle pillar. This will open a secret door leading to the switch behind the gate.

If you look at the map, there should be a 3x5 room to the east of the iron door. In the center of that room is a pillar. Use what I mentioned earlier in this room.
