Yeah it's an interesting dungeon, and like every new one I find I die the first time I saw it.

Since this is a spoiler page, before you go try to get some cold resistance and buy some (greater?) healing potions. Lots of stuff in there hits HARD from a distance. There's also (at least) one kind of attack you haven't seen before....
I was also amazingly unlucky the first time I played Trollshaws in beta4. The first level had a huorn (at character level 1!) which I barely survived, then when I came back from Bree there was an anaconda on top level and on second level I died to a mountain troll
thunderer. Fortunately it seems like that was a really awful series of dice rolls!
Has anyone else notice that item destruction is either nerfed or broken in beta4? I usually end up carrying a bunch of potions and scrolls and so far have not lost even one to a fire or acid trap.... (I don't know if this is a bug or if it was just severely nerfed from earlier betas.)
