In order to use Amiibo figures in Zelda: Breath of the Wild you must turn the functionality on first. To do so, press start and move to the right menu. From there you will see an options section. Turn Amiibo functionality on in the options menu and you’re ready to go. Once you have turned on Amiibo functionality press and hold up on the D-Pad. Navigate to the Amiibo option and then press the L button. Once you have done all that, place an Amiibo figure on your controller. You can use each Amiibo once a day.
