Question #1,
How do you stealth ( Rank 3 )

Question #2,
When your looking for the crystal room and you get to the elevator but it says you need to repair it, and when you do repair it, straight down the hall from the mechisum room is a forging room/blacksmithing room. My question is, does anybody know how to use that room in the correct order to make somthing?

Answer #1,
At the middle of the screen there is an icon parted in four. For each parted filled with white you are harder too see. What stealth 3 does is increasing this a lot so you are harder to spot and next to invisible in darkness. Remember though that enemies can still hear you so only by walking you will be completely unnoticed.

Answer #2,
The blacksmiths are for making swords and they require a metal bar. You should have found a book describing how they are used in the first blacksmith after chasing the ghoul and infiltrating the warehouse. The order is:
- put bar in pot by 'using' the pot,
- use the wheel to turn the pot over the fire,
- use the big blowing device so the metal melts,
- use the wheel again so the melted metal flows down in the shape,
- use the handle for cooling the newly shaped blade,
- 'use' the fire for warming up the blade until it glows red,
- 'use' the blacksmith in the middle for laying the blade on it,
- slash the 'blacksmith hammer' at the blade once,
- 'use' the blade on a handle tool at a table in the side of the room, this spawns a sword ready to use.
