Weapons and armor exclusive to Legend of Zelda amiibos in Breath of the Wild can now be found around Hyrule and The Depths in Tears of the Kingdom. Each weapon/armor is a callback to a previous Zelda game, such as Ocarina of Time and Wind Waker. It's dangerous to go alone, so if you're looking for a non-decayed weapon, you should get the Sword of the Hero.
