Every week (when the regular warlock writer hasn't been eaten by a prince of hell or something, that is), WoW Insider brings you Blood Pact for affliction, demonology and destruction warlocks. For those who disdain the watered-down arts that other cling to like a safety blanket, for those willing to test their wills against the nether and claim the power that is their right, Blood Pact welcomes you and invites you to take a seat.
Greetings once again, my dark cousins. It is time once again to dive back into the world of raiding an undead dragon's lair; I was rather hoping to be done with the whole undead part. In case you missed it, check back in with part 1 of our warlocks in Blackwing Descent guide to see how to deal with the first set of bosses within the instance.
Now that we're finally in the correct instance, there are still a few more bosses that need to be cleaned up, not the least of which is Nefarian himself. A key thing to note about Nef before we actually get into details about the encounter: He is a pretty tough fight, being the last encounter of the instance and all, and it may be possible that your raid is not yet prepared for him at this time. You may find it better to actually go out and try your hand at the other bosses in Bastion of Twilight or Throne of Four Winds instead, if you are struggling against the undead dragon.
