The Legend of Zelda: Tears of the Kingdom includes an array of new armor sets that help Link fight his way through Hyrule. Many of the new armor additions have a massive impact on gameplay, such as the Froggy Armor set. However, players of the game's forerunner, The Legend of Zelda: Breath of the Wild, will have set their sights on familiar armor sets. Luckily, the new Zelda game retains the best armor sets from Breath of the Wild and Hyrule Warriors: Age of Calamity, including the Barbarian Armor.
