Blackrock Mountain: Blackrock Caverns Jan 12 2011
I'm skipping the Northrend dungeons for now to get these guides for the new content out quicker, but don't worry, I will be releasing videos for all the Northrend dungeons.
Blackrock Caverns is the first instance of the Cataclysm expansion. Located in Blackrock Mountain on the border of the Burning Steppes and Searing Gorge it is a level 80-83 dungeon. You must have discovered the instance entrance in order to queue for this dungeon using the Random Dungeon Finder, as with all Cataclysm dungeons. There are five bosses: Rom'ogg Bonecrusher, Corla Herald of Twilight, Karsh Steelbender, Beauty, and the final boss is Ascendent Lord Obsidius.
