Wahgo Katta Shrine
The shrine is located just north of the Riverside Stable.
On the right side there are a number of metal blocks with grating on them that Link can climb up. Climb up to the top and open the treasure chest to get an Amber gem.
There is long metal plate on a higher platform in the corner. Use Magnesis to grab each of the metal blocks and stack them so that they are close to that platform. Grab the long metal plate and drop it do the ground floor.
Now once again stack the three metal blocks on top of each other, this time so that they are closer to the altar. Then place the long metal plate so that it sits on top of the stack of metal blocks, while also serving as a ramp, leading to the altar. Climb up the blocks and run up to the altar to meet with Wahgo Katta and get a Spirit Orb.
Climb up to the initial treasure chest to get an Amber.
