Shae Mo'sah Shrine
The Shae Mo'sah Shrine is one of the many Shrine of Trials found in Breath of the Wild.
The Shae Mo'sah Shrine is located at Goron City, along the path leading towards the Abandoned North Mine.
In the first room there is a floor switch that needs to be pressed down. The easiest way is to step on the switch and then use Stasis to keep it pressed down. Alternatively, Link can use a Fire Arrow or flaming weapon to burn down the nearby ivy. This will lower a barrel which can be placed on the switch. A well-thrown Remote Bomb can also bring down the barrel.
Run past the first gate and turn left to find a treasure chest that contains a Stone Smasher. Continue on and fight two Guardian Scout I's and a Guardian Scout II. Be sure to open the nearby treasure chest that contains a Ruby. Then head up the ramp.
Ignore the locked door here for now and continue onward. Climb the stairs to find a platform with a switch on top. Just beyond the floor switch, down below, there is a treasure chest which contains 10 Ice Arrows.
Climb back up and step on the switch, which will cause a flame to drop down. Link can use Magnesis to grab the flame, causing it to hit the ivy. Alternatively, Link can shoot it with an Arrow. Once the ivy burns, this will cause a metal ball to roll down the chute until it hits a gate. You can also ignore the switch entirely and use Magnesis directly on the metal ball and move it onto the track below the wooden platform it is sitting on.
Follow around the corner and there is another floor switch. Step on it and it will cause the ball to roll down, causing the wheel to spin. This will temporarily open the nearby door, so run on through before it closes. Open the chest here to get a Small Key.
Climb up the ramp and then drop down. Backtrack around the corner all the way to get to the locked door. Use the small key and head on through. This final puzzle has multiple solutions. However, by far the easiest solution is just step on the floor switch, use Stasis, and then run on through. Run up to the altar and speak with Shae Mo'sah to get the Spirit Orb.
Use Stasis to keep it pressed down. Open the chest around the corner for a Stone Smasher. Take care of the Guardian Scout II. Open the chest tucked away to get a Ruby. Another chest here contains ten Ice Arrows. Open the chest to get a Small Key.
