- Were you looking for the original Upper Blackrock Spire dungeon, before it was changed for the Warlords of Draenor expansion?
This article concerns content exclusive to Warlords of Draenor.
For a limited time, during patch 6.0.2 (the pre-Warlords of Draenor release event), a special level 90 version of the instance was open to players, featuring new bosses tied to the Warlords of Draenor expansion. These bosses included: Orebender Gor'ashan, Kyrak, and Commander Tharbek.
The Blizzard announcement for this event read:
"An advance party of Iron Horde forces has barged right out of the Blasted Lands and pushed all the way to Blackrock Mountain, where they found refuge and supplies in Upper Blackrock Spire. There can be only one response: the Alliance and the Horde of Azeroth must face this iron incursion head on."
This instance was updated, with a Heroic mode (level 100) version for the Warlords of Draenor expansion. In addition to the three bosses mentioned above, this permanent version contains two additional bosses: Ragewing the Untamed and Warlord Zaela.
