For me, the Act 1 BF level 2 dungeon was COMPLETELY unpopulated. <img src="/ubbthreads/images/graemlins/disagree.gif" alt="" /> I ran through the first two floors collecting loot and then casually picked up the copper amulet of piercing unmolested when I descended to the 3rd floor.
I found the level 3 key later and when I went there, there were ghosts, evil eyes and earth elementals throughout the first 2 floors. On the 3rd floor I encountered THREE quest bosses...two gargoyles and a giant spider. Thankfully, they only came out one at a time. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
