This November marks the 15th anniversary of World of Warcraft, and we have some special things planned to celebrate the occasion. Players who log in during the event period will receive a celebration package in the mail with a Lil’ Nefarian pet and some other in-game goodies. Throughout the duration of the event, you’ll be able to participate in three unique raids with iconic encounters from past expansions along with an old-school-inspired Alterac Valley battleground. Players who defeat all nine bosses in the raid wings will receive the Obsidian Worldbreaker, a Black Dragonflight mount inspired by Deathwing. Players who participate in Alterac Valley will receive a new anniversary event currency which can be exchanged for two new mounts: the Stormpike Battle Charger (Alliance) and the Frostwolf Snarler (Horde).
