A character gets a special ability/power related to his cliché if the cliché is 4 or higher.
So the Barbarian from The Frozen Wastelands (4) might have “Listen to the Ice”, which grants him one roll to know instinctively who crossed a certain patch of land before him, in the last three days or so. Or he might have “Ice Sword Maker”, which gives him the ability to craft a sturdy weapon out of ice.
