Burning Crusade Timewalking Event: September 30 - October 5

Through Monday, October 5, players at level 71 and higher can (and should!) queue for Burning Crusade Timewalking Dungeons. You’ll be rewarded with loot that has been scaled to your level, and you’ll face the challenges of:

The Arcatraz
Black Morass
Mana-Tombs
The Shattered Halls
The Slave Pens

Before you head into the depths of Outland, make sure you pick up the quest “A Burning Path Through Time”, which rewards both a Seal of Inevitable Fate and an Iron Fleet Treasure Chest*.

*Chest practically guaranteed to contain a Hellfire Citadel item in the ilvl 690-705 range.

Which of the bosses in these five dungeons is the most challenging in your opinion?
