Honkai Star Rail 3.3 Hyacine's kit Leaked

With the official announcement of "Castorice" and "Anaxa" in Honkai: Star Rail 3.2 banners, Trailblazers, are your Stellar Jades ready? Meanwhile, the upcoming 3.3 banners have been mostly confirmed—Hyacine set to debut in the Phase 1 banner, a new character introduced in Version 3.1’s story, while Cipher in the Phase 2 banner.

In this article, we’ve compiled everything we know so far about Hyacine ! Get ready to see what surprises this sunshine, rainbows, and little white pony-themed character will bring to the game! 🌈✨

 

Basic information

As the city-state in the clouds crumbles through time, the Twilight Courtyard opens its gates once more, bringing a glimmer of light to Evernight. You, Physician Hyacinthia, Chrysos Heir who guards the Sky Coreflame, must inherit your ancestors' will and mend the torn fabric of dusk and dawn.

May the rainbow light pour down, dissolve all grudges, and bring the dawn back to this land.

"It's you who healed the sky."

As the inscription on Hyacine’s splash art suggests, she is a descendant of the heavens—a golden-blooded guardian entrusted with preserving the embers of the celestial flame. Her very existence is tied to the skies, embodying themes of renewal, hope, and divine duty.

According to currently known information, Hyacine is expected to officially debut on May 21, 2025, in the first phase of the Version 3.3 banner as a 5-star Wind-type "Remembrance" healer, specializing in high-speed HP-drain healing.

As a character following the Path of Remembrance, she possesses a unique "Memory Spirit"—the adorable rainbow-white pony seen in her official artwork.

Moreover, as the long-rumored dedicated healer for Castorice, she is an absolute must-pull character. Aside from her strong synergy with Castorice, she also performs exceptionally well when paired with other mainstream DPS carries.

 

Skill

Hyacine specializes in high-frequency, small-scale healing, and when placed in an HP-drain team composition, she can additionally unleash Harmony Path support capabilities. For Castorice, Hyacine is an indispensable presence.

● High-Speed HP-Drain Healer

Hyacine is an HP-drain healer, falling under the HP buffer category. She triggers HP-based buffs by draining HP, making her compatible with all main DPS units that rely on HP buffs—such as Castorice, Mydei, and Blade. Her HP-drain and healing mechanics are explicitly designed to synergize with Castorice's kit.

● Highest Speed Stat in the Game

Additionally, Hyacine boasts the highest Speed stat in the entire game, allowing her to potentially act multiple times in a single turn. This enables her to cast healing skills at an extremely high frequency, ensuring the team doesn’t collapse due to HP-drain mechanics. If her Speed exceeds 180, she can even trigger Tribbie’s passive to charge the Herta’s ultimate.

● Ultimate Skill

According to leaks, despite being a healer, Hyacine’s Skill deals strong single-target Wind damage. Her Skill and Ultimate can switch between Day and Night states—during Night mode, she can spam skills without cooldown (focused on healing).

Furthermore, her Ultimate has an additional effect: Skill Point recovery. Her Eidolon traits include a revival effect. Since Bailu already has the ability to revive allies, Hyacine’s revival mechanic might apply to her Remembrance Spirit (the rainbow pony)—though there’s still a chance it could revive teammates directly.

The image above is a thoughtful fan recreation of her ultimate animation—while slightly abstract 🤣, it still clearly shows that Hyacine’s burst unleashes a rainbow and her little white pony, followed by a healing effect.

 

Light Cone

According to leaks from an anonymous source, Hyacine’s signature Light Cone may include the following effects:

1. Healing Boost

• Increases healing output, compensating for Hyacine’s smaller heals and making her a more reliable sustain option.

2. Speed Buff

• Helps push her Speed above 180, allowing her to trigger Topaz’s passive and charge the Black Tower’s ultimate faster.

3. Energy Regeneration

• Potentially provides extra Energy recovery for Hyacine or the entire team.

4. Damage Buff (Conditional)

• May grant ATK/DMG bonuses to allies under certain conditions.

💫 Trace

The leak also suggests that Hyacine’s Traces might include a "Revive" mechanic. If true, she could become a top-tier support like LingSha or Gallagher, especially excelling in high-difficulty content.

 

Relic

2-Piece Bonus Increases the wearer's SPD by 6%. When the wearer's Speed is 135/180 or higher, increases the wearer and their memosprite's Outgoing Healing by 12%/20%.

The newly released inner relic set "Giant Tree of Rapt Brooding" is clearly unsuitable for all current Abundance characters, because existing healers can hardly reach 180 speed. Considering Hyacine's high-speed configuration, this is obviously a dedicated relic set prepared for Hyacine.
