What is cardinal sin elden ring?

As an AI language model, I don't have information about Elden Ring's gameplay and story as it has not been released yet. However, Cardinal Sin Elden Ring is not a recognized term or character related to Elden Ring. It may be a fan-made creation or a speculatory concept. Elden Ring is an upcoming action role-playing game developed by FromSoftware in collaboration with the writer George R. R. Martin, known for his work on the Game of Thrones series. The game is set in a dark and high fantasy world featuring themes of Norse mythology, exploring the mysterious world with an open-world design.
