How to reach the location with the masked enemy?
Location: Hirata Estate [Bamboo Thicket Slope]
Rewards: Random lesser loot, Mist Raven's Feathers - these items are in the cabin guarded by the enemy. You can use them to craft a new prosthetic tool.
Start at Bamboo Thicket Slope Sculptor's Idol. Turn left, climb the ledge and then jump into the water. Swim under the bridge and grab the branch behind it (picture 1). Reach the small ledge and start looking for the bamboos presented in picture 2. Attack them to open a passage. You reach a well - jump from one wall to another to get out of it.
Reach the house on the hill (see the picture above). The masked enemy is standing on its rooftop. He will attack you when you get close to the building.
Fighting the purple enemy
The purple enemy focuses on fast attacks with his katana combined with jumps. You can deflect them if you are good at parrying, or you can dodge these attacks and wait for a good moment to strike back.
The masked enemy also can perform an attack that can't be blocked - it will be telegraphed with a red symbol. The mini-boss kicks you with a lot of strength - dodge it at the right moment.
Run around the house guarded by the enemy if you need time to heal yourself or take a break. The enemy also has problems with jumping on the wooden beam - use this to your advantage and attack him a few times. Remember that you have access to various items, e.g. Shinobi Firecracker. this item can stun the purple enemy for a brief moment.
The purple warrior doesn't have any red dots - this means that you can finish him off with a Deathblow after filling up his Posture bar. Alternatively, you can just keep attacking him to deplete his health bar.
