Kaya Wan Shrine
The shrine is located directly to the west of the Wetland Stable.
Shields from Water
In the next room, defeat the Guardian Scout, and then use Cryonish to lift the chest from underwater. Make your way over to the treasure chest and open it to get an Ancient Core. Then use Cryonis to make your way over to the next area.
This next part can be a bit annoying, because if you fall in the water, you will likely have to restart the area. There are two Guardian Scouts in the distance and I recommend trying to defeat them with arrows, before getting on the raft, if possible. A raft will appear and can carry you towards the end of the shrine, but there is a treasure chest we want to collect, so do not get on the raft yet. Use Cryonis and make your way from ice block to ice block, being careful not to fall in the water. On the left side of the room, use Cryonis to lift the gate, revealing a treasure chest behind it. Open the treasure chest, which could contain a Knight's Broadsword or even Royal Broadsword.
Carefully make your way past the gate again without falling in the water. From here, you can use the raft that appears, or the ice blocks to make your way to end of the water. From there, use the Paraglider to reach the altar. Speak with Kaya Wan to get the Spirit Orb.
Alternatively, use Cryonis to create a set of stopper blocks for the raft, then use the raft as a walkway to the pedestal the first Guardian was on. Setting blocks at the edge of the waterfall prevents you from going over the edge, and allows you to climb up then easily paraglide to the Monk.
Use Cryonis to create an ice block and climb up the waterfall. Use Cryonis to reach the chest to get an Ancient Core. Use the Paraglider to reach the altar.
