Gu Wanyue

If your blade does nothing to Gu Wanyue, the Wailing Wraith, that is the fight working as built: she starts out invulnerable to normal strikes, and the way in is to parry her purple fireball back at her or to hit her with the Heartrend Pipa. After that it is a fight of 53,410 HP on one bar, with no second phase, against a wraith who floats and flies around a flooded village square with a red candle shrine at the far end in Pangzhen, and whose grabs take nearly half of Soul's health. She is a required main story boss of Chapter 7, The Heart's Trail, and drops Fanatic's Fragment: Fixation, half of the material that tempers the Fanatic's Broken Blade.

Quick facts

The Pond of Fading Song

Rest at the Pond of Fading Song bell in Pangzhen before you go in. Walk toward her in the flooded square and her name bar appears. The Sha-Chi Powered Boat quest's other boss is Wu Xuan, the Fallen General (AllThings.how). No achievement names her, but the story one for leaving the Village of Lu for Pangzhen stood at 55.3% of Steam players on Nov 9, 2026, the ceiling on how many could have reached her square eleven days after launch.

Getting through her invulnerability

• Break her invulnerability. When she laughs at long range as purple flames gather, parry the fireball right as it reaches you to send it back: it deals direct damage, burns her, and leaves her open to your combos. PCGamesN gives the same cue: parry the blue projectile when she glows purple.
• Or bring the Heartrend Pipa, an Artifice Phantom Edge with 276 starting damage and 234 guard break, which hurts her while she is still invulnerable. It drops from Yuzan in the Village of Lu (Phantom Edges).
• Stay locked on. PCGamesN: "This boss is hard to track, as she flies around, so keep locked on."
• Attack in the short pauses between her moves; strikes during her attacks tend to miss or get interrupted.
• Treat the dark and her vanishing as warnings that a grab is coming, and heal at range after she finishes a move.
• Read her colors as the game teaches them on Combat: the blue projectile and the blue final hit of her arm flurry are parried, the red-glint handstand grab is dodged.

Grabs, darkness and the scream

• Purple fireball: a laugh, then purple flames. Parry it back at her.
• Darkness: the arena goes nearly black. Game8 says the darkness always ends with an unblockable attack or her fireball, so stay back and listen for the laugh. AllThings.how adds that it cannot be deflected and that she uses the cover to set up grabs; PCGamesN suggests blocking through the dark to break her guard.
• Flying grab: she vanishes out of reach, then dives back and grabs Soul, often after one dodge and an advance. Stay back, keep your guard up, and do not rush in after a single dodge. It deals about 683 HP on Pathbreaker, nearly half of Soul's 1,402, and comes twice a fight.
• Flying sweep: an unblockable grab from the air, including when she leaps up from the ground first. Dodge it.
• Handstand grab: a half backflip onto her hands with a flashing red glint, then a forward kick that grabs with her legs. The animation makes it the easier grab to read. Dodge it.
• Arm swing flurry: a spinning arm combo. Parry it: each deflected hit drains a large chunk of her Guard, and a perfect parry on the blue final hit opens a Ghoststep counter.
• Sleeve lash: a wide sweep that reaches farther than her body suggests. Retreat or dodge through it.
• Crossed sleeves: at close range she thrusts both sleeves into an X. Move sideways rather than trading blows.
• Spinning leap: she jumps and spins with her sleeves fanned, then lands on Soul. Dodge out from under her as she rises.
• Scream: the air distorts and the screen blurs. It cannot be deflected; dodge out of its path.
• Purple aura: red sparks and purple energy before an attack. Stay clear until it fades.

On Wayfarer, AllThings.how saw a sneak grab take about 479 HP, and her health stays the same on every mode (Difficulty Modes).

Sanchuan and the well

At the end, she speaks of a cold, lonely man's voice from the bottom of a well, Sanchuan, and of dying beside him if they cannot live together; the Well of Wei Sanchuan is nearby. PCGamesN says the well is where the Mandate Encampment gate key waits.

Her Fanatic's Fragment: Fixation, a Weapon Soul Tempering Material whose card reads "A fragment born of a hopeless wait", joins Fanatic's Fragment: Attachment, from Yan Qiansui in the quest Allure of Vanity, to make Fanatic's Obsession, the material for the Fanatic's Broken Blade won from Hua Qianxiao (Weapons, Side Quests).
