A guide on how to find and complete the Rin Oyaa shrine and solve the "Directing the Wind" puzzle.
How to Find the Shrine
From Hebra Tower, go northeast along the road to find this shrine next to Snowfield Stable.
How to Solve the Shrine
Go down to the lower level and use Magnesis to pick up a magnetic block. Look for the ramp that leads to Rin Oyaa. At the base of the ramp, there is a fan, and above that fan, there is a shorter part of the wall. Place the magnetic block on top of that shorter wall, to the left or right of center. Find the second magnetic block on the lower level and put it on top of the shorter wall, next to the first one.
Then go to the opposite side of the room from the ramp that leads to Rin Oyaa. There is a ladder that takes you back to the area where you entered the shrine. Go up the ladder and pick up the orb. Take it down to the lower level.
Look for the fan that is pointed at a short ramp. There is a metal walkway nearby that is between a fan and the target hole. Stand near that metal walkway and near the fan pointed at the short ramp. Set the orb down, then use Stasis to freeze that fan, then throw the orb in front of the frozen fan. Then run underneath the metal walkway and run up the tall ramp so you're standing on the flat platform at the top. If you did it correctly, you will reach the platform before the fans blow the orb into the target hole, and you will be raised up to Rin Oyaa.
Before you talk to Rin Oyaa, jump over the metal blocks and open the chest to get an Ancient Core.
Then talk to Rin Oyaa to get the Spirit Orb.
