Glory of the Cataclysm Raider

Enter Blackwing Descent, Bastion of Twilight, and Throne of the Four Winds on Heroic difficulty to be eligible for all sub-achievements in this meta. The two hardest sub-achievements are Keeping It In The Family and The Abyss Will Gaze Back Into You, while the remaining achievements are generally completable in LFR-level gear.

Throne of the Four Winds is the most straightforward of the three raids; complete it first to get Stay Chill out of the way, as this achievement was historically the most difficult but has since been made easier due to nerfs to the Gather Strength mechanic.

For The Only Escape in Bastion of Twilight against Halfus Wyrmbreaker, kill two drakes at the same moment; if the healing reduction drake is active, pop all three drakes and kill two or three simultaneously, then burst Halfus down quickly. Dodge drake fireballs throughout the encounter.

For Double Dragon, eat the first large meteorite but avoid the second and third, as taking them deals massive damage in the Twilight Realm. This achievement can be completed during a solo run if you can defeat the encounter itself.

Once all sub-achievements are completed, you will receive Reins of the Drake of the East Wind along with a letter from Thrall on behalf of the Earthen Ring acknowledging your accomplishments across the Cataclysm raids.
