Sha Gehma Shrine, also known as Shift and Locke, is one of the many Shrine of Trials from Breath of the Wild.
The shrine is found at the very north end of the N. Tabantha Snowfield. The shrine is guarded well as there are three White-Maned Lynels in the area surrounding the shrine.
Shift and Lock
The first chest can be found on the higher ledge to the left. Climb up high enough and then use the Paraglider to reach the chest, which contains a Royal Broadsword.
A second chest can be seen, with a large magnetic block on top of it. Use Magnesis and grab the metal block. Lift it upwards so that it is above the moving blocks. When one of the moving blocks is below it, release Magnesis and then quickly change to Stasis. Freeze either the block or the moving platform, which will give Link enough time to drop down and open the treasure chest to get a Small Key.
Use the small key on the locked door and then run over to the alter to meet with Sha Gehma to get a Spirit Orb.
