Killed my bear and got my pelt. Of course, I got jumped again by the Lich of Miragul on the way out, but at least I'm done with that cave. I swear he must walk around invisible or something with how many times he's come out of nowhere; usually I'm pretty good about avoiding random aggro. Now I just need to get a few more pieces, make some medium banded, and I'll be all set.
Interestingly, this time, his pet was an enchanter pet instead of a skeleton. Actually, I think it might've been a skeleton just before he aggroed me and then he summoned an enchanter pet when he aggroed.
