Maybe you’ve try to look around circling the location but can’t find a way to enter Shakkei Pavilion Domain? Well, we’re on the same boat.
Turned out you have to destroy the block using Kamuijima Canon.
How to Unlock Shakkei Pavilion Domain?
Go to Kamuijima Canon location:
Get Electrogranum From Closest Thunder Sakura Bough
This canon only can be operated with Electro energy from Electrogranum, so before you press “Operate” on canon get your Electrogranum first (located besides the cannon)
Aim for Shakkei Pavilion Domain Entrance, Then Fire!
Adjust it like image below as reference. Mine looks hollowed out because the wall already destroyed.
Get The Achievement: Jackpot
If the gate destroyed, the entrance will appear and you will get Jackpot achievement.
Done, Check The Domain
Now go open it to unlock domain teleport waypoint, there’s also 1 electroculus inside.
