[spoiler] The third boss: random?

[seth]

Hey,

soo.. I only recently started playing this game. Up to now it has been pretty fun, but the Lich is.. annoying. Those black bullets keep randomly killing me, because the he teleports right on top of me. When I hear the teleport sound / see the black shadows it is too late most of the time. Is there some pattern to his teleporting or is it just supposed to be like this? (just in case that matters: I'm playing a warlock in hard mode)

best wishes
seth

Well, it is random, the warlock is probaly the most difficult class to kill bosses with, but with enough time put into it...
