The Legend of Zelda: Breath of the Wild players will be all too familiar with the game's Great Fairy Fountains, which are back for the sequel, you'll need to visit them yet again to beef up your armour.
Zelda: Tears of the Kingdom is home to four Great Fairy Fountains, just like Zelda: Breath of the Wild before it. But rather than being roused by the promise of thousands of Rupees, you unlock the Great Fairy Fountains in Tears of the Kingdom with a serenade; although you'll need to tick off a handful of quests involving a traveling musical troupe called The Stable Trotters.
You won't be able to interact with the troupe unless you become a reporter for The Lucky Clover Gazette which kicks off a series of side quests. So first thing's first: make sure you're prepared for the journey to Rito Village, located to the south of Hebra Mountains. You'll need some form of cold resistance to get there safely, so cook up some toasty meals and make sure you've grabbed the Archaic Greaves (part of the Archaic armour set).
