Located near Icecrown Citadel, the dark stronghold of the Lich King Arthas, the Pit of Saron is the second wing of a three-part instance known as the Frozen Halls. As a high-end dungeon intended to gear players for early raiding during "Wrath of the Lich King," this instance has stricter requirements than other Lich King dungeons. Until you become attuned, you have to fight your way through the Forge of Souls first.
Level and Gear Requirements
The minimum level to queue for the Pit of Saron via Dungeon Finder is 78, while the minimum level to walk in is 75. Players must also have a minimum overall item level of 180 to qualify for running the Pit of Saron, regardless of whether they queue or walk in. Quests in the Pit of Saron and the previous wing, the Forge of Souls, require level 78.
Quest Requirements and Attunement
Accessing the Pit of Saron by walking in requires you to complete the quests inside the Forge of Souls. While a portal to the Pit is available, attempting to walk in before completing the quests in the Forge of Souls will result in failure, and a message instructing you to complete the questline. Once you complete the quests, you can use the portal at any time.
