What's with the red force fields and the tunnel? I think I probably missed a switch or something, though I ended up having to use TGM to get through.
Oh and the place where I got Keening, this tunnel switch like thing said I needed lubricant, where would that be?
-edit: Ah I found the hidden door, hopefully this helps me out.
TGM? You're skipping all the fun =(
Fake Keening was brilliant, but I have to say (as came up during one GDR related thread a while back), my absolute favorite trap was
Spoiler the Ebony Arrow of Slaying, which I saved specifically for when all might seem lost with the assumption that the end-fight was going to be rather tough. :facepalm: Fortunately, I made it out of the maze and back to the heart chamber in time...
Foolish Nerevar =)
And yes, save often, because you'll need it. Darknut crafted amazing ruins and you will suffer greatly before the end!
