Story
The story follows Link, the main protagonist, being told by Zelda to head back to the Shrine Of Resurrection. Once arrived, Link must put the Shiekah slate back in its resting place, revealing the One-Hit Obliterator. When you take it, it will drain your health to a sliver, leaving you vulnerable to die in one hit in exchange for killing monsters in a hit. After completing the challenge on the Great Plateau, you will truly begin the story. You learn the stories of the champions and how they were assigned to each of their Divine Beasts. After finishing their trials, you must fight a blight from the past. After completing the battle, Link discovers the true power of each Champion's power, making it charge faster.
