In order to reach the final three we first had to go through Kin'garoth. The changes from heroic are not extremely significant, but as always all mechanics hurt more and dodging the purple orbs is a must.
The second hurdle was Varimathras. The biggest change to this encounter is the spawning of extra adds which must be kept to a minimum and they have to die as soon as possible. As soon as everyone executes correctly the Necrotic Embrace movement pattern, the boss should be dead!
Next stop: Coven of the Shivarra!
