The Orochium Shrine can be found near the Snowfield Stable in the Tabantha Tundra northwest of Rito Village.
You’ll need to complete the Courage to Fall challenge to clear this shrine. Start out by heading down the stairs then use Ultrahans to open the doors of the structure. Next, follow the path left of the doors and fight the enemy at the end. There will be a section of wall hanging out on the right. Use Ascend to reach the top of it then climb up the ladder and crouch through the gap in the wall on the right. When you reach the other side, turn to the right and glide down to the area below. Take out the enemy here then pass the doorway looking to the left. There will be one more enemy guarding a chest with 5 arrows inside.
Return to the doorway and open the doors then crouch walk past the lasers. There will be two enemies here that you’ll need to deal with. Afterward, return to the lasers and walk through one. This will open up the floor causing you to drop down into a hallway with more lasers. Dodge them heading under the platform at the end. Use Ascend here to reach a chest. Open it to receive the small key then use Ascend again.
Head down the stairs and use the key to unlock the door allowing you to grab the ball. Head up the stairs behind the room with the ball and use one of the moving platforms. This will take you up where you can drop the ball in a pressure plate opening a gate and gaining you access to a wing with some fans on it. Pull out then stick the ball to the top. Set the wing on the track and ride it back to the starting area by hitting one of the fans. You can then unstick the ball and place it on the floor plate opening the door leading to the altar where your Light of Blessing awaits!
