Legendary items just not doing it for you anymore? Then prepare to get your hands on some artifact weapons. Set to become the highest level of WoW item quality, Legion will feature 36 artifact weapons and each one will have its own questline relevant to the class and specialization that wields it.
Artifacts have their own ability trees and grow in power alongside the wielder. The upgrades a player assigns to an artifact not only grant the item new skills and traits, but it also alters the look, feel and even the sound of the weapon - allowing for a greater level of customization.
There'll even be some artifact variations that can only be attained in the form of special rewards in PvP.
