cw8: Holy crap. Anyone did the Abandoned Thaig in Sundermount in Chapter 2, the one with a Golem selling a 84g ring inside? 1 word to describe, crazy, CRAZY number of mobs...
Luckily managed to lure a manageable wave at a time in the corridor.
It is indeed crazy. I had to leave and rebuild my party because of the big room with them Golem store. Absolutely insane fight. I can't tell if all the rooms are cut off normally so that we can only explore two big rooms but I finally beat it with a party of Fenris, Aveline and Merrill.
As for lockpicking, so far my Hawke is doing a good job of opening all locks. I think even complex ones. I mainly put stats in her dexterity and cunning, so far so good.
