Gwent's version of card packs in other CCGs.
Each keg has a total of five cards in it that a player adds to their collection upon opening it in the shop. The first four cards are always random. For the fifth card, the player can choose from three different, randomly chosen options of the same rarity. Kegs can be purchased in the in-game shop in exchange for ore or real money. Additionally, kegs can be earned through the Reward Book.
