Tibia Coins are a new currency in a game. They are available in packages of different sizes. Once bought, Tibia Coins are available to all characters on your account and you can immediately access them from within Tibia.
There, you can spend them in the Store. The Store is a new, convenient interface that is accessible directly from within Tibia. It allows you to browse through a wide range of Tibia products for your character. If you fancy something from the Store for your character, you can buy it via Tibia Coins without having to leave the game. Moreover, once bought, you can use a product such as an amount or a Character Name Change, for example, right away.
