One of your primary five senses is highly developed, allowing you to spot what others miss. You may take Perception Tests to detect normally imperceptible details with the associated sense, as dictated by the GM. For example, you might be able to hear the difference between the cry of one wolf and another, or taste the difference between the exact same vintage of wine bottled on two different days. You may take this Talent multiple times, choosing a new sense each time you do so.
