The Treasure Goblin Pet is the World of Warcraft version of the Treasure Goblins that appear in Diablo III. Those of you who purchased the Collector’s Edition of the Diablo III: Reaper of Souls expansion have access to your very own Treasure Goblin (in World of Warcraft). It is among the special items that Blizzard created that are “crossovers”.
Some of you that have been spending a lot of time playing Diablo III: RoS might have forgotten about this little World of Warcraft related freebie. Take a minute to log into WoW and pull this little guy out of your mailbox.
