Yubi, No. 21 Swordfighter Puppet

Yubi, No. 21 Swordfighter Puppet is an optional Phantom Blade Zero boss in the Training Grounds of the Mandate Encampment, opened with the key from the Chief Disciple of the Seven Stars. Parry her blue-glint finishers, perfect dodge her red flip kick and knee-spin thrust, and finish Secrets of the Baishan Sect first. She drops the Baishan Stormswords and the Broken Vessel.

Yubi, No. 21 Swordfighter Puppet waits in the Training Grounds of the Mandate Encampment, which 36.8% of Steam players had investigated by Nov 9, 2026; 23.5% had freed all four Great Puppets, she among them, for the trophy The Four Freed. Game8 ranks her second among Phantom Blade Zero's hardest bosses, behind only the Gold-Masked One, for "one of the most aggressive set of attacks", an afterimage that follows up each attack and a second phase with ranged attacks. She is optional, and she falls to defense: perfect blocks and parries drain her Guard meter faster than trading hits ever will. Her Baishan Stormswords are a very useful weapon in the second half of the game, PCGamesN says.

PowerPyx's Oct 29, 2026 recording shows the Training Grounds as a dirt yard in front of a long hall with a tiered roof: at 0:27 the pale puppet stands in a low sword stance a few strides from Soul, just before her bar appears.

The Training Grounds Key

Her arena is in the Mandate Encampment, which opens only after Gu Wanyue in Pangzhen (KeenGamer). Beat the Seven-Stars Formation for the Training Grounds Key, which opens the arena at the Training Grounds. PCGamesN puts her at the end of the map, as the first numbered puppet.

Finish Secrets of the Baishan Sect first

Maxroll warns that if you fight her before the tale is done, you miss the Broken Vessel accessory; the step before her is inspecting the body in the flowerbed after Wu Lengshuang, the Soft Sword. AllThings.how says the fight itself is the tale's step to defeat Bi Taotao's puppet form, and that a spear puppet fights beside her. The fight also gives the Illusory Pipa Backplate, which Game8 says you need to enter the Mountain of Imprisonment. Because the Broken Vessel can be lost for the playthrough, it is listed on Missables; the whole Baishan tale is on Side Quests.

Defense wins

Do not trade hits. She is very aggressive, and trading often goes badly.
Perfect block. Game8 calls perfect blocks the most consistent way to drain her Guard meter and stagger her for free damage.
Parry blue, dodge red. Both trigger Ghoststep counters, which open windows for heavy damage and extra Guard loss (Combat).
Learn the openers. Learn how her parryable combos begin so you can be ready for the final hit.

Her combos and where they end

Slash-Thrust Combo to Jumping Slash: two vertical slashes and a thrust, ending in a jumping slash. Parry the final blue-glint hit for a Ghoststep counter.
Jump Dash: after vertical spinning slashes she leaps and dashes in with a strike you can parry.
Cyclone Thrust: a left-hand slash, then a heavy right-hand thrust. Parry the thrust.
Flip Kick: a forward flip kick with a red glint, unblockable, often at the end of a combo or from neutral. A perfect dodge triggers a counter that takes roughly 15 to 20% of her Guard meter.
Spinning Knee Slash to Thrust: she drops to her knees for low spinning slashes, then an unblockable thrust. The low spins are the warning; dodge the thrust.
Electrical spins: PCGamesN says a red attack comes right after, so time the perfect dodge.
Leap into the sky or onto the roof: be ready for a red attack immediately after.

Game8 says her afterimage follows up each of her attacks, and that she turns to ranged attacks in her second phase; no guide yet breaks that phase down move by move.

Wind and Thunder: the Baishan Stormswords

The item card calls them "the Baishan Sect's sacred treasure, capable of channeling the power of wind and thunder", once wielded by Bi Taotao. Activating both the Wind Sword and the Thunder Sword enters Baishan's Blessing, a 20-second Attack boost (30 seconds at weapon level 25), and Block plus Heavy Attack during it releases Lightning Storm. Steam's achievement stats show players picking them up late: 12.3% had used Lightning Storm (the achievement Baishan Tempest) by Nov 4, 2026, and 21.6% by Nov 9, against 33.2% who had finished Secrets of the Baishan Sect. Every weapon is on Weapons.
