Halls of Stone is a level 77-78 dungeon. It is located in Ulduar in northern Storm Peaks, just west of Halls of Lightning. There are three bosses: Krystallus, Maiden of Grief, and Sjonnir the Ironshaper, as well as an encounter with the Tribunal of Ages in which you must protect Brann Bronzebeard while he accesses the archives (hacks the computer).
Halls of Lightining is a level 79-80 dungeon located in Ulduar in northern Storm Peaks. There are four bosses: General Bjarngrim, Volkhan, Ionar, and Loken. This is my solo run; I also did a dual-boxing run which you can find here.
Sorry for such a long time between videos lately. I kind of lost interest in Warcraft for a while and got busy with work, but hopefully I can get back to a quicker release schedule.
