Lost City of the Tol'vir - Dual Boxing Nov 19 2012
It's been a while since I've done a proper dungeon guide video, so here you go. Lost City of the Tol'vir is a level 84-85 dungeon for 5 players. It is located in Uldum near the bottom centre of the zone. There are 3 bosses (General Husam, High Prophet Barim, and Siamat) and an optional fourth (Lockmaw). On Heroic difficulty there is another boss (Augh) that joins the encounter with the optional boss Lockmaw. This instance is easily soloed by a level 90 character (I haven't tried Heroic difficulty yet).
More videos to follow. Enjoy!
