Fate Dice are a type of polyhedral dice used in the Fate RPG system, which is a role-playing game focused on storytelling and character development. Each die has two sides marked with a plus sign (+), two sides marked with a minus sign (-), and two blank sides. Players roll four Fate Dice to determine the outcome of actions based on their character's skills and abilities. The results of the roll can range from negative to positive, influencing the narrative of the game. Players can use these outcomes to create compelling stories, resolve conflicts, and enhance character interactions, making Fate Dice a key element in the Fate RPG experience.
