Go into the fight, pop your grindstone buff, by the time you get it off, he’ll miss his shoulder charge, and you can easily R2 Parry with Two Dragons to start with insane damage. 4-6 parries later, staggered. His phase 1 is done in 60 seconds typically with this. Phase 2 fury attacks are easy R2 parries along with his sky flip combo.
did it with pipe wrench. After about of dying, mostly to phase 2 being relentless, even with perfection stone. Its like i went ultra instinct, and i parried so much and just wrecked the boss using some s from Visceral attacks as well. What a game. Absolutely frustrating at times but now that its done, i am glad. I do hope we get a sequel. Possibly not AS hard but still challenging. We will see though.
The timing on that is trickier than your normal perfect block because it take a windup time, but yeah, It's great when you get it because it's an instant heavy attack after a perfect block
