Ariorb Vel'Kera (Heroic)

Strategy
He is the only healer in the group (heals tick for over 1 million). It is advised to kill him first and fast!

Keep the party away from the mob when it emotes. The mobs has many aoe's but they aren't that devastating. Combined group has lots of hp and you need to be able to manage the adds as well. Having a group with strong tank and aoe is a must for this encounter.
