The Crimson Halls of the Icecrown Citadel unlock this week!

  • The Blood Princes and Blood Queen Lana'thel will be unlocked.
  • You will get 15 attempts to defeat the final boss of each wing (Putricide / Lana'thel). So far we assume that the amount of attempts is shared between bosses. (And I'm sure blue posters will clarify that a hundred of times)

If you still have trouble understanding how the raid unlocks work, here is a nice flowchart! Thanks to Dorer
