As the above poster said, make sure you have your healing streams and your frost resistance totems up.


Secondly, make sure that you have a strafe macro for your guys that is separate from your tank (if you have one). Make sure that you have cast bars of target on. Blizzard has a cast time. As soon as you see him casting it, strafe your guys to the left. For the next cast, strafe them back right back to where they were. Rinse and repeat until he's dead.

As for being stuck, Novos is a skippable encounter. Just follow the wall to the left as you enter, and you can just skip him and go into the bat room and on to King Dredd and finally the prophet. Until my guys were a little bit better geared I just skipped him. But now that I have a bit better gear and the strafes down, he's a piece of cake.
