Thanks

.
I was thinking about making a "teleport" thing. I have no experience with that though and my mind was beginning to wander to another map that have been on the drawing board... :S.
The stone, sqeezing through is a very nice idea. But that kinda breaks a thing with the map, as one of the things in the module was that the goblins would break the dams in the upper chamber at the waterfall and the water would rush down to wash away the heroes

. I plan to do that the old fanshion way (you know describing with words ;)).
I tried to be true to the original. that does give some headache in Divinity

.
I might get to the teleport thing though, so thanks for the offer of the snippet!
