he Obsidian Tank takes the high armor/health/durability of the warrior class, and adds to it the defensive capabilities of the Elementalist Earth Magic enchantments. It's purpose is to take/hold aggro and soak up damage. It is strictly a PvE build with little use outside of very high level areas like the Domain of Anguish and Sorrow's Furnace, where variations of this build have been a staple for ages. It pairs very well with a monk bonder build.
