Swordmaster Sekiro - Corrupted Monk (Ashina Depths) Hardmode Flawless
One of my favourite fights when you actually fight her. Very enjoyable and fair to deflect!

'Additional Hardships' from not carrying Kuro's Charm (increases difficulty and introduces chip damage on 'block' but not 'deflect')
Bell Demon on
No prosthetics
No combat arts
No damage or stagger taken
