In Burning Crusade Classic, many instances are locked if you don't complete certain quests or increase your reputation with certain factions. These restricted instances also lock out access to later raids in the expansion.
In this guide, we explain how to access the Auchindoun instances on Heroic difficulty once you reach Level 70. This includes the Mana-Tombs, Auchenai Crypts, Sethekk Halls and the Shadow Labyrinth.
Important: All players in the group must have the Auchenai Key to access any of these instances in Heroic Difficulty. If one of the players doesn't have it, they'll be left at the entrance.
To access Heroic difficulty for the instances mentioned above, you must have the Auchenai Key, sold by Nakodu in the Lower City of Shattrath, in the Terokkar Forest.
However, in order to obtain this key, you must reach Revered reputation with the Lower City.
To reach this level of reputation quickly, we strongly advise you to farm the Auchenai Crypts over and over during your leveling from about 64-66 — which should guarantee you Honored — and then complete all the quests in the Terokkar Forest once you reach level 70.
This not only maximizes your reputation gain as you level up, but also increases the amount of gold generated at Level 70, since you earn extra gold instead of experience when you complete quests at max level.
