The Code adds 2000 Guild Wars 2 In-game Gems. Add the Gems using the Black Lion Trading Company in the Gem shop from within the game.
Gems are the in-game currency required to purchase things from the Gem Store. Gems may be bought with real-world money and spent to get convenience items, account services, or decorative items. Like in-game items, they can be traded to other players for coin at the Trading Post.
The Gem Store allows players to purchase various items using gems as currency. It is accessed through the Black Lion Trading Company. Most items purchased are immediately delivered through the Mail. With Gems you can buy Styles, Consumables, Services, Accounts, Boosts, Minis or/and Updates.
