To actually access amiibo rewards, press the L button and select the amiibo icon. This brings up a targeting reticle on the ground. This circle indicates where amiibo items will drop. Just scan any amiibo you want with your controller’s NFC receiver (the top of your Pro Controller or your Joy-Con’s joystick) and watch loot fall from the heavens. Just don’t stand under it. Otherwise, a metal chest just might clonk Link on the head.
Tears of the Kingdom: Every Amiibo Reward
Like Breath of the Wild, Tears of the Kingdom is compatible with every amiibo. Most provide generic rewards such as meat and fish, so by all means, scan your Monster Rise Magnamalo and Diablo 3 Loot Goblin if you want bananas raining down on you.
However, again like Breath of the Wild, Tears of the Kingdom’s best amiibo rewards are linked to figures depicting Legend of Zelda characters. These include figures from the 30th Anniversary, Breath of the Wild, Tears of the Kingdom, and Super Smash Bros. lines. If it’s a Zelda character, the amiibo scan function will spawn several materials and a chest that contains special items such as glider fabric, a weapon, and a piece of armor. While the glider fabric is guaranteed, the rest are subject to a loot table. Sadly, that means you will never know which item you’ll get, if any, until get you’ve scanned the amiibo. Plus you might obtain a duplicate. Still, the rewards are worth it.
Before you start scanning amiibo, you should keep in mind that you can only scan an individual figure once per day (unless you use save scumming). That being said here are all the amiibo that provide special rewards:
The Legend of Zelda: Tears of the Kingdom Link – Champion’s Tunic Fabric (first time only)
The Legend of Zelda: Breath of the Wild Link Archer – Tunic of Memories Fabric (first time only)
