Witcher Senses are used extensively throughout The Witcher 3 such as in one contract when tracking a werewolf - its tracks run up a tree, forcing Geralt to find another clue to keep on track; when he finds a tuft of werewolf fur, a scent trail becomes visible to his senses and the hunt resumes. Another example is a contract that has the player looking for a leshen. Knowing that crows serve leshens, Geralt focuses his senses and follows the sound of crows to the leshen's totem.
