The Right Roll
Pick up the metal orb and place it on the line in the middle of the ramp. It will roll down and hit the glowing wall target, which will rise up, opening the path to the next area.
Attach the two orbs together and place them over the angled ramp so that one orb is on one side of the ramp and one orb is on the other side. Let go, and they should roll down the ramp without falling off. When they hit the glowing wall target, the path to the next area will open.
In this area, there are three orbs. There is also a treasure chest on a ledge in the corner. Attach the three orbs together, with the medium orb in the middle, then lean the three attached orbs against the ledge with the treasure chest. Use Ascend on the leaning orbs to get on top of them, then open the chest to get 10 arrows.
Then take the three attached orbs and place them on the curved slope such that the largest orb is on the left and the smallest is on the right. You may need to do some trial and error to find the correct placement and distance down the slope to place the three orbs so that they roll and hit the glowing wall target. When you hit the target, the path to the end of the shrine will open. Go through and check on the dragon ring to get a Light of Blessing and complete the shrine.
