Corpse-Eating Xue Boss Guide: Mass Grave Fight & Rewards

Who Is Corpse-Eating Xue?

Corpse-Eating Xue is boss number 32 on Rock Paper Shotgun’s 61-boss list, an optional Maskwalker duel buried in the Mandate Encampment’s Mass Grave. Game8’s optional-boss table files her with the Maskwalkers and lists no direct reward — the real prize is what her death unlocks. Her in-game dossier, preserved by Game8, is one of the game’s bleakest sketches: a farm girl who came to the Mandate in admiration, now crawling among the gravestones and pale corpse-fire, gnawing on the bodies of Mandate heroes. Sha-Chi corrupted her wounds and eroded her mind — the heroes she revered became her food, and not long ago she was still digging graves with that rake to bury the dead. One source quirk: TechWiser’s location guide calls her “him,” but the dossier and Method.gg’s fight guide both treat her as the farm girl described above, so this page uses she/her.

How to Reach the Mass Grave

Game8’s walkthrough ties the region to Chapter 7: The Heart’s Trail. The approach:

1. Rest at the Mass Grave Bell, then descend the lower cliffs one section at a time until you reach the river.
2. On your first visit you will find a Mandate Leader fighting enemies. Help him win, then grant his request to end his life when prompted — if you leave him alive he can corrupt into a hostile and interfere with a Memory Flower needed for The Undying Heroic Spirit Tale later.
3. Continue past the river into the open battlefield. Phantombladezerodb describes the arena as a green swamp forest of red lilies and red shrine lanterns, with lesser enemies scattered around it.

TechWiser flags that Xue sits behind a locked door in the encampment; Method.gg names the key as the Mandate Valley Gate Key, so clear the surrounding camps until the gate opens. Our Mandate Encampment guide maps the region’s bells and side routes if you want to chain the nearby hunts in one sweep.

The Corpse Swarm: How the Fight Actually Works

Game8’s mechanics breakdown is the key to this fight, because the adds are not decoration — they are the boss’s health bar. Xue is the tall figure holding a rake, accompanied by four other corpses wielding random weapons. These corpses respawn infinitely, and the boss only takes damage when your blade lands on her main body or on the corpse aglow with green flames. Hitting anything else is wasted animation, which is exactly how the swarm punishes panic-mashing.

Two systems turn the crowd into a resource war:

• Weapon re-rolls. When a corpse dies, its replacement spawns holding a random weapon — so killing a corpse is a control lever: you are re-rolling what the pack holds, not just thinning it.
• Priority deletes. Game8 recommends killing any corpse holding a spear or dual-wielding garden hoes, glowing or not. The spear corpse reaches you from off-screen, and the dual-wielder chains multi-hit strikes with gap-closing jumps — the two adds most likely to kill you while you watch Xue.

Her other unfair tool is consumption: per Game8’s quest walkthrough, Xue can devour her minions to restore HP — the reason that guide says to focus her rather than the crowd. The synthesis: thin the dangerous weapons, never chase the whole swarm, and keep your damage on Xue or the green-flame corpse.

Moveset and Counters

Xue’s own kit is deliberately simple next to the chaos she generates. Her rake strings are mid-range sweep combos that are parryable but risky to answer inside a crowd; dodge out, let the corpses overextend, then punish the recovery. Her signature is a red-glowing grab attack that tracks further than its animation suggests. Sidestep rather than backpedal, since backing up keeps you inside the corpse ring where her adds cut off escape routes.

For loadout, Method.gg’s suggested build follows the same crowd logic: Jagged Steel primary with the Wild Oriole Sword secondary, keeping every attack animation short so you are never a sitting duck among the undead; Mother’s Talisman and Everflow repay you with healing for killing and guard-breaking fodder enemies. If your Sha-Chi gauge runs dry mid-swarm, weapon-swapping to refill it is the habit that saves runs — the core loop in our combat system guide.

Rewards: No Drop, a Door Opens

Game8’s reward column for Xue reads None, and that is accurate — the payoff is a door opening elsewhere. The instant she falls, the Xue, Admirer of Heroes Tale logs itself — KeenGamer’s 33-tale table lists it as Tale #25, and wikily.gg’s journal files it under the Tales tab. Finish the scavenger hunt it sends you on and the Child of Insight in Pangzhen pays the Sha-Chi Headscarf (+15 percent Sha-Chi recovery rate). The full item-by-item route lives on our Xue, Admirer of Heroes walkthrough, and the region’s surrounding hunts — including the Chief Disciple of the Seven-Stars along one of the collection routes — are indexed in the all-bosses list.

FAQ

Where is Corpse-Eating Xue in Phantom Blade Zero? In the Mass Grave battlefield of Mandate Encampment, past the river below the Mass Grave Bell. You reach her by descending the cliffs from the bell, helping the Mandate Leader at the river, and pushing into the open graveyard where the boss bar triggers.

Why is Corpse-Eating Xue not taking damage? Only her main body and the corpse glowing with green flames can be damaged. The other risen corpses are invulnerable. Kill corpses to re-roll their weapons, and prioritize spear and dual garden-hoe wielders.

What does Corpse-Eating Xue drop? Nothing directly. Beating her starts the Xue, Admirer of Heroes Tale, whose turn-in reward is the Sha-Chi Headscarf accessory for 15 percent faster Sha-Chi recovery.

Is Corpse-Eating Xue optional? Yes. Game8 lists her among the bosses you can skip, and she sits behind side-gated content. Skipping her also skips the Sha-Chi Headscarf, since the Tale only exists once she falls.
