Nioh - Sasaki Kojiro - Way of the Nioh (No Items, No Ninjutsu or Onmyo, No Living Weapon)

The healing comes from receiving an elemental debuff, (ticking healing) or landing a perfect guard (800~ heal.)
Sasaki Kojiro took around 50 attempts in total. A beautifully fast-paced fight, and really fun as well. Does hella guard damage and uses a lot of skills the player can use with the odachi, except Kojiro is able to blend and chain them together.
No too terrible difficult, a run of the mill humanoid boss, luckily without living weapon, so it's possible to parry and stagger him. Overall a really fun and enjoyable additional fight.

How did you change hair color?

[@boneslee3247]

You can change William's hairstyle at the blacksmith - if you're talking about the red, that's headgear called Takezo's Headband from the Musashi quest

@@boneslee3247 Thanks for your answer! The lightning gave me the impression that hair color was different. I reached Way of the Wise some days ago and I wanted to change William a bit haha.
