Guys, consider that I'm really bad at this game, but I can't get past the Walls of Mist in the Sky. :( Can anyone give me some tips on how to do it? :o
Next, go to the right teleporter and proceed forward into the building. Take the elevator down, and you'll find a room with pools. You need to fill the niches with water by pressing on them. After doing so, a chest will appear on the wall opposite the entrance, and it contains the eastern key.
Exit.
Then, go to the left teleporter, enter the building, and go up any staircase. Proceed to the buttons and press them until you get the correct combination. Once you have the right combination, you can press the lever. After that, a chest will appear near the entrance, and it contains the key.
Finally, go to the hall with the three teleporters and insert the keys into the columns. Once you've inserted them, the door will open. Go through the door, and you'll be out of the Walls of Mist. You can't kill the monsters in the Walls of Mist!
