World of Warcraft is turning 17 this year, and Blizzard is celebrating with new rewards as part of a special anniversary event.

As detailed by Blizzard, starting November 15 and lasting December 6, players will receive a celebration package in the mail that includes fireworks and an item to increase experience and reputation point gains by 17%. Two daily quests will also be available for completion that involve answering World of Warcraft trivia or battling various world bosses from vanilla WoW in exchange for Timewarped Badges, which can be used to purchase various rewards like toys, pets, and transmogs.

The event is similar to previous anniversary celebrations, with one major new addition. A new weekly quest will pit players against the Burning Crusade world boss, the Doomwalker, alongside new rewards like the Doomwalker Trophy Stand toy and Illidari Doomhawk mount. The addition of the Doomwalker ties in with the release of Burning Crusade Classic, a new version of the game's first expansion, earlier this year.
