Boss: Novos the Summoner
Difficulty: Easy
I run up the stairs and position my chars to one wall near the middle of the stairs. Then I engage Novos and setup Magma Totem. Elite Mobs can be burned easily. As soon as Novos can be attacked i run down the stairs, set up my totem parc (Grounding, Healing, Wrath etc.) , use frostaura and spread my toons. Then it should be easy tank'n'spank. BONUS: If you kill Novos this way, you should earn an achievement for Glory of the Hero. =)
