Obsidian armor

Description
The Obsidian Armor is a set of prestige armor art available to all the professions for each of their armor sets, and some of the special armor pieces. The Obsidian Armor does not have the new armor type such as + Health. Besides the cool looking, the armor does the same thing as the 1.5k a piece armor. As with other prestige armor arts, it's only available as level 20 armor.

A recurring theme between the Obsidian art of many of the professions seem to be "spikes" and "black", although the Ranger, Monk, and Mesmer Obsidian art definitely don't have spikes.

Only the Warrior, Assassin, and Ritualist Obsidian art includes the headgear. All other professions only has four pieces.

Note that, while each armor pieces cost 15 (except for Ascetic's and Cabalist's), the Obsidian Armor is typically not considered 15k armor.

Where to get it
Obsidian armor must be crafted by the Eternal Forgemaster within The Fissure of Woe. To be able to get the Forgemaster to craft any armor, players must finish the following quests:
 * The Eternal Forgemaster
 * Defend the Temple of War
 * Restore the Temple of War

Materials common to any Obsidian Armor: Obsidian Armor also always require additonal crafting materials.
