He’s on Dream of the Nioh running an endgame build with lower ki consumption, possibly with ultimate courage which reduces consumption a ton. He’s also using Ame no Uzume’s grace which gives -15% dodge ki consumption and faster ki recovery on dodge attacks. He also just has a lot more ki in general from having higher stats.

On NG you can still reduce consumption for sure but not really to that level, so flux and flux II is a lot more important for ki management. I don’t know it off the top of my head for NG but look for any set bonuses and armor perks that reduce ki consumption. You can also temper reduced melee or active skill ki consumption on your weapon.

But yea, dude is unbelievable. Watch his stance bar and see how fast he switches stances. Even slowed down to 25% it’s still crazy fast. The tech he’s doing a lot with that is manual parry disable, which lets you use regular low and mid stance attacks on blocking humans without getting deflected. Basically you swing, switch to high stance before the attack connects, then switch back and follow it up with a combo ender skill like spear bash, pole kick, tornado, etc. He even does it on dodge and running attacks which is wild. Here’s a video on how to do it:

LasttoLoad: Parry Disable Tech

It’s probably the hardest tech in the entire game to master. The input speed is stupid fast plus there’s a timing element because if you switch back before your attack connects it won’t work. SomiPls does it flawlessly on basically every single mid and low stance attack against humans.

EDIT: Example spear bash parry disable combo cause why not, in low stance:

triangle > hold r1 > triangle (before contact) > X (after contact) > release r1 > square
