World of Warcraft is introducing Arfus, the beloved ghostly dog inspired by the Lich King, as a collectible pet in both Wrath of the Lich King Classic and the retail version. Previously featured in Hearthstone’s Knights of the Frozen Throne expansion, Arfus has been an unofficial mascot for the Classic WoW development team. Now, this spectral pup is available for players, boasting two distinct models: a lower-resolution version for Wrath of the Lich King Classic and a higher-quality design for Dragonflight.

Arfus will serve as an Undead battle pet, allowing players to level and utilize him in the mini-game encounters within World of Warcraft. In Wrath of the Lich King Classic, players earn Arfus by completing a new meta achievement, Defense Protocol Gamma, in the upcoming Fall of the Lich King update. For Dragonflight, an achievement titled The Lick King—likely associated with the Hallow’s End event in World of Warcraft Patch 10.2—will unlock Arfus.
The impending Fall of the Lich King marks the final major patch and raid season for Wrath of the Lich King Classic. Meanwhile, Dragonflight’s Patch 10.2, Guardians of the Dream, initiates the third raid season, potentially concluding significant story arcs in World of Warcraft. Details about Dragonflight Patch 10.3 remain uncertain, leaving fans eager for potential announcements during the forthcoming Blizzcon event.
