Glory of the Hellfire Raider

This meta-achievement requires completing 9 individual boss achievements across Hellfire Citadel. The previous mount reward, Reins of the Corrupted Dreadwing, is now purchasable from Dawn-Seeker Krisek using Apexis Crystal.

Enter Hellfire Citadel and defeat Siegemaster Mar'tak while completing the Nearly Indestructible achievement. If defending cannons proves difficult on Mythic, attempt this on Normal difficulty instead.

Defeat Iron Reaver while completing Turning the Tide. The required adds may not spawn on Mythic difficulty, so run this on Normal to reliably trigger the achievement mechanic.

Defeat Kormrok while completing Waves Came Crashing Down All Around. This achievement can be completed by simply defeating Kormrok while meeting the encounter's challenge condition.

Defeat Gurtogg Bloodboil and the Hellfire High Council for Don't Fear the Reaper. Kill all three council members within 10 seconds of each other — loot is located on Dia Darkwhisper.

Defeat Kilrogg Deadeye while completing A Race Against Slime. This achievement is straightforward and can be completed during a normal kill of the encounter.

The Gorefiend achievement cannot be soloed — bring at least one other player who has a battle resurrection, or bring two additional players. This is the only boss in the meta that requires a group due to the achievement mechanic.

Defeat Shadow-Lord Iskar while completing his associated achievement. This can be completed during a standard kill of the encounter.

Defeat the mech, enter the mech, then use the prison spell (ability 3) on the light-blue portal and wait for Socrethar to defeat the mech. Do not immediately attack the mech or adds after this happens or it may become unkillable — wait for the mech to move before attacking, then repeat the cycle until the encounter ends. If the mech becomes unkillable, run toward the doors to reset it.

Defeat Mannoroth while completing his associated challenge achievement. This encounter's achievement is among the more notable ones in the raid alongside Socrethar's.
