Pin Mastery occurs when a pin reaches its maximum level and does not evolve. At this level, it will move from the Stockpile Tab to the Mastered Tab in the Pins Menu of your phone. Mastered pins are stronger than their unmastered counterparts and it is one of the goals of The World Ends With You to master all your pins. There are three methods of mastering pins. The first is to use Battle PP which is gained by battling noise. The second is to use Mingle PP which is gained from either mingling with other players or encountering aliens. The final method is to use Shutdown PP which is gained by not playing The World Ends With You for some time.
