A guide on how to find and complete the Sha Gehma shrine and solve the "Shift and Lock" puzzle.
How to Reach the Shrine
This shrine is in the Hebra Region. Go north from Rin Oyaa Shrine and cross N. Tabantha Snowfield to find this shrine. However, be careful of the Lynel in N. Tabantha Snowfield. Alternatively, you can go northeast from Rok Uwog Shrine to avoid the snowfield area.
How to Solve the Shrine
Use Magnesis on the metal box in the middle of the room, and go up the ramps that spiral around the track that the metal box is attached to. Raise the box above the two moving platforms. When a platform is about to move under the box, switch to Stasis and freeze the moving platform under the box. Your goal is to change the timing of the two moving platforms such that there is always a platform under the metal box, so it can't fall back downward. You will need to manually deactivate Stasis on the platforms in order to get the correct timing (as opposed to letting Stasis wear off on its own).
After you have accomplished this, go down and open the chest that was under the metal block. It contains a small key.
Go up the ramps again and float down to the treasure chest on a pillar. Open it to get a Royal Broadsword.
Then use the small key to open the door to Sha Gehma. Talk to Sha Gehma to get the Spirit Orb.
