if you are bout the soul carin exit. it the same you got in
It is about after retrieving the soul essence gem and getting back to the stairs. In my game you cannot go back through the portal, because there is none--just a grate where it once was. You can jump down from the roof however.
I did that and then spent well over an hour trying to get back to the stairs which --in my game-- is impossible. If I follow the compass leading to the stairs I find myself blocked by the blue force field. I covered every inch of that ground and couldn't even find the stairs. I can't even see it in the distance. It is as though it is behind the blue barrier. I don't know? But, it matters not now, because I deleted all of the saves leading up to when I fist got to level 10: And, have started over much to my chagrin.
