What this fight tests
Arena control against a mobile opponent in the tightest section of the game.
How to beat Kui Yanyan
- Learn the arena edges first. The Mountain of Imprisonment arenas are narrower than anything earlier.
- Do not chase her into the wall. Her mobility is worth more when you have no reset space.
- Use the transition window if the fight has one — invulnerability cuts both ways, and it is your only free heal.
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.
The mistake most players make
Playing the same chase game as the open-air fights. The geometry changed; the approach has to as well.
Note on sourcing: this entry is confirmed as part of the launch roster (name, region and placement), but its attack patterns have not been corroborated by a second source yet. The advice above is drawn from the universal boss loop rather than from a verified moveset breakdown, and is labelled accordingly.
