What this fight tests

Pure Sha-Chi discipline. He takes no meaningful damage until the bar is fully depleted, which makes every non-parry hit you throw a wasted animation.

How to beat The Gold-Masked One

Stop attacking. Deplete Sha-Chi with parries first; the health bar only opens after the break.
He is fought three separate times across the game. Each encounter raises aggression, so the parry habit you build in the first one is the whole strategy.
Motion-captured by Donnie Yen — the tells are deliberately smooth, so read the flash colour rather than the body language.

The loop underneath all of it is the same one every boss uses: parry the blue flash, Ghoststep the red one, drain Sha-Chi, then punish the stagger with Power Surge. Phase transitions are invulnerable — heal and reposition instead of swinging into them. And dying in a later phase restarts you at that phase, not at the beginning, so you can throw attempts at the hard half.

Most guides file him under Mo Yuan — the encounter's actual name, and the spelling that follows it around search. Commentated, with a stated easy method; fitting for a boss whose difficulty is a single habit. — via Trophy Guides on YouTube

The mistake most players make

Treating the invulnerability as a bug or a gear problem. It is the mechanic: aggression without parries accomplishes literally nothing here.
