Yubi Phantom Blade Zero Boss Guide

Where Yubi Appears and How to Beat Yubi

Yubi is an optional boss in the Training Grounds of the Mandate Encampment, and the fight is beaten with perfect blocks, blue-glint parries, and red-glint dodges. For Yubi Phantom Blade Zero, every move and reward below comes only from the linked guides. The Game8 page recommends perfect blocks and parries to break Yubi's guard because she is highly aggressive. The phantom-blade-zero.games guide adds that you should stay off Yubi's attack line and parry the blue finisher.

• Block Yubi's combos and parry the blue flash that ends them to break her guard and create openings.
• Dodge the red-glint unblockable flipping kick and the kneeling thrust; neither can be blocked.
• Use an off-axis approach and parry the blue finisher to keep pressure on Yubi.
• Watch for attacks that can cause paralysis, and treat the blade-cross lightning ring as the deadliest move.

Yubi Weakness: Openings and Guard Breaks

Yubi has no elemental weakness, according to metabot.gg, so the useful route is damage and guard breaks. Perfect blocks are described as a consistent way to drain Yubi's Guard meter and stagger her, while the Game8 guide treats parries as the answer to her aggression. The howtovideogame.com guide adds that blocking combos and parrying the blue flash creates openings. Use those openings instead of chasing elemental damage.

Attack Pattern and Tells

Yubi's cited attack pattern is read through colour tells: blue-glint combo enders can be parried, while red-glint moves must be dodged. Yubi's blue-glint combo enders are the main parry check. The Game8 page says you should parry the blue-glint combo enders and dodge the red-glint unblockable flipping kick.

The howtovideogame.com guide adds the kneeling thrust to the red-flash unblockable list and describes attacks that can cause paralysis. The phantombladezero.help guide calls the blade-cross lightning ring Yubi's deadliest move, so keep that move in view when the fight speeds up.

Drops and Rewards

Defeating Yubi yields the Broken Vessel and Baishan Stormswords, according to Game8 and thegameswiki.com. The phantombladezerodb.com page lists the Broken Vessel accessory and Baishan Stormswords as Yubi's rewards. The howtovideogame.com guide also places the Illusory Pipa Backplate in the building past her arena, which is a separate pickup from the boss drop. Check the Baishan Stormswords page and the accessories page after the fight.

Before You Fight Yubi: Missable Tale Check

Defeating Yubi before completing the current Secrets of the Baishan Sect objective can fail that tale, according to howtovideogame.com. Check the objective before you start the optional fight, then use the missables page to keep the tale in view. The bosses page can help you place Yubi among the other Mandate Encampment encounters.

Our take on the Yubi Fight and Mandate Encampment

Our take on Yubi Phantom Blade Zero is that the fight is a guard-break check rather than an elemental puzzle, with the red-glint unblockables as the main danger. The Steam store page lists Phantom Blade Zero as an action RPG developed by S-GAME Studio and published by S-GAME Publishing, with a release date of 28 Oct, 2026, a standard edition price of S$69.90, and Very Positive English user reviews. The linked guides place Yubi in the Mandate Encampment, name blue-glint parries and red-glint dodges, and list the same two rewards.

The pbzerowiki-site.pages.dev boss page lists Yubi as No. 21 Swordfighter Puppet in the Mandate Encampment, so the optional-boss label is consistent across the pages. The bosses and combat pages are useful next stops if you want more context before or after the fight. Keep the red-flash moves as the main danger and use perfect blocks to turn Yubi's aggression into Guard damage.
