How to beat Mu Xiaokui in Phantom Blade Zero (and unlock her secret phase)

Updated: Last verified:
Quick answer

Mu Xiaokui, Soul’s childhood friend, closes the Village of Lu. She fights as the Young Mistress of the Order and then as the Queen of Iron and Jade. If you gathered the five red ribbons from the tale “Young Mistress”, a secret phase appears with the Jade Dancer and the Iron Fiend. Don’t back off: she dominates mid-range.

Where she is and how to get there

Past the Lakeside bell, at the end of the Village of Lu.

How to beat Mu Xiaokui

Phase 1: Young Mistress of the Order

Aerial slashes, thrusts, cutting waves and purple rifts that release enemies. Stay close to her.

Phase 2: Queen of Iron and Jade

She fights unarmed with punch combos and summons guardians. The Iron Fiend opens fissures in the ground.

Secret phase: Iron Fiend and Jade Dancer

Only if you completed “Young Mistress” (five red ribbons scattered around the village). It’s the hardest fight in the area: save first.

How do I get through the Jade Dancer and Iron Fiend phase?

Tips from players on the Steam forum (not official):

  • Focus on the Iron Fiend first: he is the easiest to pressure while you dodge the Jade Dancer’s blades. Once he falls, she is left alone.
  • Switch weapons when you run out of Sha-Chi: switching refills the bar instantly.
  • Don’t wait for clean openings: the pressure never stops; alternate attack and defense on the fly instead of looking for a long window.

Are there QTEs (button prompts) in this fight?

The game has few QTEs: according to players on the Steam forum, only a handful of bosses ask for a series of button presses to finish them off, sometimes by mashing a button. If you fail, the sequence repeats. On the forum there is a report of a QTE that didn’t respond in the second phase of the next story boss (going by the Chinese name the thread uses, it would be Blaze, in Pangzhen) and soft-locked the playthrough; the answer was to load the last save. S-GAME support noted the request for an option to skip QTEs.

Strategies to beat it

Pick the one that suits the way you play. We only recommend gear you can have when you reach the Village of Lu.

Strategy with fast weapons (one-handed and dual)

She is a fast opponent: don’t chase the long combo. Land two or three hits and back off before she answers. The best options here are White Serpent & Crimson Viper and Wild Oriole Sword. Punish up close after each thrust, and keep your other weapon in reserve: switching restores all your Sha-Chi.

Strategy with heavy weapons (two-handed)

Against such a fast opponent, use heavy hits only after a parry or a perfect dodge. Try Scarlet Wraithblade or Outlaw Warblade. The Outlaw Warblade restores health on hit, ideal if you struggle to stay alive.

Elemental strategy (exploit their weaknesses)

She is weak to lightning, ice. Equip:

  • Lightning: you won’t have gear of this element yet; if you come back later, use the Thunder Spear (Chang Hong’s Phantom Edge that also paralyzes).
  • Ice: you won’t have gear of this element yet; if you come back later, use Whiteshadow (two-handed weapon from the Blizzard Blademaster).

Defensive strategy (parries and dodges)

Her most dangerous attack is the mid-range cutting waves: learn the animation and always dodge it. Parry every blue flash to drain her Sha-Chi without spending yours, and execute as soon as she’s stunned. If you’re struggling, the Counterstrike Bracers accessory (first Long Pillar) rewards parries.

Strategy with Phantom Edges

Bring the Iron Gauntlets to break her guard or defenses and, if the summon icon glows in the arena, the Puppeteer’s Bell so someone distracts her while you heal. Remember that sparks recharge when you rest at a bell: spend them freely on the boss.

If you get stuck

  • Upgrade your two main weapons before going back (the boss is level 9).
  • Upgrade your medicines with the healer at the Green Serpent House once you have access.
  • Drop to Wayfarer: it doesn’t affect any trophy and you can raise the difficulty again later.

Recommended gear

  • Fast weapons to pressure her at mid-range.
  • Upgraded medicines.

Rewards

  • Wild Oriole Sword.
  • Puppet No. 44’s Eye.
  • Secret phase: Fiend Saws and Fist Fragment: Core.
  • Trophy Will We Meet Again? (silver).

Frequently asked questions

Where are Mu Xiaokui’s red ribbons?

There are five, scattered around the Village of Lu. Pick them all up before the fight to trigger the secret phase.

What do I do if a QTE doesn’t respond?

According to player reports on the Steam forum, if you fail a QTE the sequence repeats. If the game doesn’t register your presses and you can’t progress, load your last save.

Stuck somewhere?

Search for a boss, a weapon, a trophy or an area.
