I did this instance today and wiped once on Novos and killed him 2nd time. imo its a bit luck-based, the first time my healer got the curse, then the blizzard on top of him, then novos targeted him for frostbolt spam. he died and it led to a quick wipe. The second time my tank got the curse and the damage was spread out a bit more so I was able to heal through it all and kill him no problems.

Still, now that I've killed him once I'll just skip him and do trollgore/t-rex/skelley probably, Novos just isn't worth the waiting-around-for-adds and stuff for 1 extra badge.

I went to Halls of Stone and did the first two bosses easy, but the "event" wiped me twice and I gave up for now. I think I'm going to work on mastering UP next, I would love to get a blue proto drake mount (ANY PROTODRAKE! Stupid Oracle eggs just giving out crappy pets...)
