Blizzard's very popular MMO World of Warcraft celebrates its 16th anniversary this month, and the developer is throwing a party to mark the occasion.

The event was supposed to start later, but Blizzard moved it up due to the release date changed for the Shadowlands expansion. Available now through November 22, the anniversary event adds special rewards, including an Anniversary Gift Package that comes with items that increase reputation and experience gains by 16% to reflect the game's 16th anniversary. The gift bundle also comes with a special invitation to initiate a quest in Orgrimmar or Stormwind, depending on which faction you're aligned with.

There is also a new vendor in the world who sells items from previous anniversary events, as well as a new Crafted Clock of War you can buy to use for transmogrification. The Korrak's Revenge PvP event also come to WoW with the anniversary event, and it allows you to earn new mounts.
