Artifact

Artifacts are a special type of weapon introduced in Legion, and the only weapons players would wield over the course of the expansion.

Players can acquire these new weapons early in the expansion's run, and the weapons grow in power alongside them. Artifact Power can be earned by engaging in most types of play, and can be spent to unlock a unique tree of traits, enhancing abilities. Players can also obtain relics and use these to upgrade the artifact itself. Artifacts also come with an extensive range of visual customization options.

There is an artifact for each class specialization, 36 in total, plus an additional one for Fishing. Obtaining each artifact involves a unique questline to seek out these powerful weapons.

Following the Broken Shore experience, players set about acquiring the artifact for their character's current specialization. The artifacts represented a greater power than the heroes of Azeroth had ever wielded before, a power which was needed in order to defeat the Burning Legion.

The process of acquiring an artifact is determined by the character's class and spec. A catch-up mechanism was added to reduce the time taken to earn artifact power for secondary specializations and alts.

Patch 7.3.5 added the send-off for artifact weapons and as such ended the Legion storyline, with the weapons having to be used in order to neutralize the sword Sargeras used to impale the world in Silithus. Some visual effects represented the instability that resulted from the send-off, with for example Artifact Power varying wildly.

With the release of patch 8.0.1, the artifact weapons can continue to be used as normal weapons, but all traits added to the weapon was "burned away", and disabled. The main artifact ability was also no longer usable, however, some were introduced as talents to the class (such as Wake of Ashes). Any relics added to the weapon would continue to increase the weapon's item level, but no longer offered any traits. Netherlight Crucible augments also ceased to benefit the weapon. All artifact traits were disabled as the final result of the artifact instability.

As of patch 9.0.1, the ability to transmog any artifact appearance for any Specialization was made available, previously players were only able to while within its corresponding specialization.

Artifacts can be customized and powered up at order halls with artifact power, earned from adventuring, completing quests, beating dungeon bosses, winning PvP objectives, and so forth. Artifact power is used to unlock traits which increase the power of the weapon and the character.

Each artifact has a unique "trait tree", a grid overlaid upon the outline of the weapon itself, resembling the old talent trees. Players can spend artifact power to activate additional traits, moving along the tree; once a trait is activated, all connecting traits become unlocked. Many traits have multiple ranks. Majorly impactful traits are called golden traits.

Artifacts also have Relic slots. Relics are artifact-only objects with a major impact on the overall power of the artifact, such as its basic damage and item level. The relic system acts as a substitute for the upgrading of weapons seen in previous expansions; rather than switching to a new and more powerful weapon, the player slots a new and more powerful relic into their artifact.

Several different looks are available for each artifact. These can be unlocked through various activities. One look for each artifact will only be available through PvP. Each look appears to come with unique flavor text, and background lore. Players are also able to unlock three additional colors of the various looks. In the case of Feral and Guardian druids, changing the look of the weapon also changes the look of the form to match. In addition, it is hard to obtain items for every specialization that unlocks an additional appearance (with 3 recolors unlockable).

Artifacts can be transmogrified into other weapons, but other weapons cannot be transmogrified into artifacts.

• Official art

• Allari the Souleater states that her weapon, the Scythe of Souls, is an artifact like the ones adventurers use. Maximillian of Northshire believes that his sword Excaliberto is an artifact, even though it's actually just a normal sword.
• Felo'melorn, Doomhammer (artifact), Thas'dorah, Legacy of the Windrunners and Talonclaw are family heirlooms.
• Felo'melorn and the Doomhammer do not have any rightful hereditary claimants, as the royal Sunstrider dynasty of Quel'Thalas and the Doomhammer line of the Blackrock clan are extinct.
• Talonclaw of the Highmountain Tribe was accepted by the tribe and the spirit of its last owner as rightfully belonging to the hunter player, as they successfully retrieved it.
• Ownership of Thas'dorah is up in the air, as the Windrunner family and its former owner, Alleria Windrunner, are still alive. Vereesa Windrunner gave her blessing for the hunter player to use it until it can be returned to Alleria. Sylvanas Windrunner proclaims to the Horde player in Undercity that such a skilled marksman is worthy of the bow. After meeting up with her and the Army of the Light, Alleria herself states she may reclaim it one day should she have need of it, but for now, she has a different path and that the player has proven themselves worthy of wielding it.
• The Axe of Cenarius was considered by Blizzard for the artifact for Arms warriors, but the developers thought that a wooden, nature-themed axe didn't fit the class. Ultimately, Strom'kar, the Warbreaker was used instead.
