Patch 6.1.2 is a minor patch for World of Warcraft that added the [WoW Token] to the game.
Introducing the WoW Token[]
Coming soon to an Azeroth near you: the WoW Token, a new in-game item that allows players to simply and securely exchange gold and game time between each other.
Players will be able to purchase a WoW Token through the In-Game Shop for real money, and then sell it on the Auction House for gold at the current market price. When a player buys a WoW Token from the Auction House for gold, the Token becomes Soulbound, and the player can then redeem it for 30 days of game time.
The WoW Token feature will be enabled at a future date. Patch 6.1.2 adds in the framework needed for the WoW Token feature in the game client and is not active at this time. Check out WoW Token Coming Soon – Additional Details for more details on how the feature works.
