Kaya Wan Shrine
The name of this Shrine's trial will refer to how you handle the many Guardian Scouts that are scattered throughout this Shrine.
Cross the pool of water using Cryonis. To get over the waterfall, make an ice block off the side of the wall.
In the next room, kill the Guardian Scout by shooting at it. Then use Cryonis to bring up the treasure chest in the water. Open it for an Ancient Core.
Cross using Cryonis to the next room and shoot the next two Guardian Scouts. Use Cryonis to get to the gate on your left. Push it up with another ice block and then Paraglide to the treasure chest behind it for a Knight's Broadsword.
You will want to Paraglide carefully, if you fall into the water the current will carry you faster than you can swim against it and you will likely die.
Return to the hallway of water and use Cryonis to get all the way to the end. Then Paraglide down all the way to the monk's quarters for your Spirit Orb.
