Azjol'nerub was merely a setback for the final boss we face in the Trial of the Crusader. Anub'arak (too many apostrophes in the Nerubian language, I say) decides to crash the party and Arthas' powerful shockwave drops you right into his lair. We're put face-to-face with the Traitor King himself, even though we've already bested him once in Northrend.
This is one of the simpler fights in terms of mechanics, compared to a very long and drawn out encounter like Yogg-Saron or Mimiron. It's by no means easy, however, and Anub'Arak's heroic 25-man version has only been conquered by a handful of guilds worldwide. Between several new fight mechanics and very distinct phases, the encounter is fast-paced and very fun from a Rogue's perspective. After the cut, I'll talk about the specific details you can use to help your raid group conquer this over-sized beetle.
