I did this successfully yesterday.

- on the four switch door - just throw the left switch
- on the top floor door with the torch's (near coffer mobs) trade a stack of Earth crystals to the door.
- on the password trap door - no password required
I completely forgot to bring a stack of earth crystals, but I can now say that the "traditional" method also works. Also, to my surprise, it is quite possible to light the torch, recast invis and make it through the door solo, even without flee.

- ALWAYS have sneak up as a low level
- some quads can aggro through the floor
- curse from the afflictor underground can reach the upper levels in some spots
To add to this:
- Avoid the temptation to kill an NM on the way. They often stand on top of caves and link everything underneath.
- Remember that OWNMs are sight aggro. Don't just run to the crest forgetting to cast invis first...
