All Zelda Echoes of Wisdom Amiibo rewards and unlocks
You can use Amiibo in Zelda: Echoes of Wisdom once you leave the Suthorn Beach area near the beginning of the game on your way towards Suthorn Village. Just open up the main menu, tab over to 'System', and select the Amiibo option. However, keep in mind that you can only scan three Amiibo a day, so choose wisely!
