If you're after help for the main game itself, then consult our Zelda: Breath of the Wild walkthrough and guide. While considered optional, visiting them will make your quest go much smoother, and are home to some of the best challenges in the game - so be sure to take the time to visit as many as you can. Introduced at the start of the game as a means to unlock Runes - special abilities Link can use to manipulate objects to solve puzzles - they later reward Link with Spirit Orbs, which can be traded in for permanent Stamina and Heart Container upgrades.
Zelda: Breath of the Wild's Shrines are small puzzle rooms that are scattered throughout the game's world.
