My current character stumbled on Sunderstone Gorge after almost dying to a ice spike machine gun disguising itself as a Necromage. (Wish I could cast that fast and accurately.) Once inside and into the main area I wanted to see if I could do it backwards, and I could. It wasn't hard jumping up the wall. The problem came when I came to the "back door" of the main chamber (has a word wall and unusual gem). The "door" is blocked by a metal spear gate. The pull chain is not within reach. To get through use the alchemy table. I didn't know if this would work. What is also nice about it, is the bad guys won't spot you if you quickly stop using the table and sneak. You can then creep over and activate the pull chain (double gate). I'll remember this in the future when I'm playing a character who wants to quickly gather all the unusual gems or word walls.
