Blackwing Descent is an interesting new raid instance. This isn't merely because it's a new instance for Cataclysm but because it draws on the heritage of the game, going all the way back to a showdown with Nefarian in Blackwing Lair.

But Blackwing Lair was just a setback.

Deathwing has raised his little boy and girl back from the grave, and they're all zombie and angry at the world. So you and 9 (or 24) of your best friends need to go kill everyone in the Blackwing Descent and make things right again. Check out our strategy guides, below, to get the skinny on how to beat down the bosses all the way up to and including the big, bad Nefarian.

Ready Check shares all the strategies and inside information you need to take your raiding to the next level. You might also be interested in our strategy guides to Cataclysm's 5-man instances, and for more healer-centric raiding advice, visit Raid Rx.
