Fated Land Walkthrough - Nioh 3

Northwest of Hamamatsu Castle lies Ryotan Temple, which Ii Naotora plans to reclaim from the yokai. If I can help in some way, I'd best lend my strength.

[1] Talk to Ii Naotora right after you exit the Eternal Rift during The Hamamatsu Incident - Part 2.

She tells you that the land she was from got taken over by yokai.

[2] Head to Ryotan Temple.

You will meet Naotora at the entrance. Talk to her to proceed the quest.

[3] Work with Ii Naotora to reclaim Ryotan Temple.
・Make your way through the temple and arrive here.

Be ready to face the boss soon!

[4] Defeat Ryomen Sukuna.

Here are some tips in going against this yokai!
・Ryomen Sukuna attacks fast so playing in Ninja Style is recommended for the mobility
・It can do a rapid flurry of attacks when you are in close-combat so make sure to evade and run away right after you attack
・You can also use your Ninjutsu to hit from afar while it's still attacking
・It does some long-range attacks when it does the burst-break attacks
・Do not use Fire/Ice weapons or Ninjutsu since this yokai is resistant to both
・USE NAOTORA! She will pull some aggro for you, enabling for you to attack more efficiently. In particular, her pulling the close-ranged attacker (the red side of Sukuna) will help
・When you enter the Dark Realm, Sukuna will shoot a lot of arrows, immediately close in on them and attack once they start shooting at the air

[5] Speak with Ii Naotora.
