Hmm, can't jump to the second tier. Maybe it was because I was getting beat on by a goblin and a couple of wolves at the time, but none of my jumps from the first tier were being successful enough to get me up there.
Oh well, guess I have to do it the 'honest' way.
@Creston - I doubt you're the only PC player, but probably in the minority. I find it totally breaks immersion to have a compass that not only tells me exactly where I'm supposed to be going (as if I knew), but also warns me in advance of anything in the area. Way too easy to find dungeons that way, imo. But it's single player, so play however you like.
