It should come to no surprise that Nintendo would add capabilities to use older amiibo figures in the new Legend of Zelda: Breath of the Wild game. This time, you are able to tap your Wolf Link amiibo on the gamepad from the Twilight Princess HD Wii U game.
You must first complete the Cave of Shadows in Twilight Princess HD and gain as many Hearts as possible. These Hearts will carry over as health for Wolf Link in the Breath of the Wild. When you tap the Wolf Link amiibo on the gamepad, Wolf Link will join you in your quest as a side companion until his health depletes. From our understanding, you can do this at any point in the game. I am assuming that this feature will be disabled during major boss battles, yet I have no way to confirm that theory. Wolf Link has the ability to attack enemies as well as hunt for food for you. Being a huge Twilight Princes fan, I am delighted to see the integration of Wolf Link into the new game!
Well done, Nintendo!
