Hyacine is a powerful 5-star Wind character in Honkai: Star Rail who follows the Path of Remembrance. Hyacine's abilities as a healer and support unit center on giving friends health boosts and recovering their health through her special companion, the memosprite Ica. Leveraging her full potential with the right Light Cone, relics, and team synergy can elevate any lineup's performance, especially those that scale with HP.

Hyacine's Role & Abilities Overview
As stated by HoYoverse, Hyacine is built to sustain her team by healing and cleansing debuffs. Her Skill allows her to summon Ica and heal allies, while her Ultimate enhances this healing and triggers the “After Rain” state for three turns, boosting the Max HP of the whole team. Interestingly, Ica also contributes to both healing and offense by tracking the healing done and converting it into damage. Hyacine is a hybrid support with subtly offensive contributions, while Ica sacrifices its own HP to passively cure injured teammates. If you haven't obtained the character Hyacine yet, we recommend that you top up Honkai: Star Rail Oneiric Shards directly, so that you can save time and energy.

Best Light Cones for Hyacine

Due to the recent introduction of the Remembrance Path, Hyacine's Light Cone choices are limited. However, her best-in-slot option is her signature 5-star Light Cone "Long May Rainbows Adorn The Sky". This Light Cone increases her SPD by 18% and causes all allies to lose 1% of their current HP when Hyacine uses her Basic Attack, Skill, or Ultimate. This lost HP is then converted into massive damage through Ica, calculated as 250% of the total HP consumed.

Moreover, when Ica activates its skill, it increases the DMG enemies take by 18% for two turns. This synergy enhances Hyacine's effectiveness in both healing and weakening enemies, especially since her passive boosts healing based on excess SPD beyond 200.

For free-to-play players, the 5-star Light Cone "Memory's Curtain Never Falls" from Herta's Store is a solid alternative. After Hyacine performs her skill, it boosts team damage output by 8% and gives her an SPD boost. While not tailored specifically to her kit, it still offers solid utility.

A budget 4-star option is "Victory In A Blink", which boosts CRIT DMG and team damage when the memosprite targets allies. At Superimposition 5, this Light Cone greatly amplifies both individual and team effectiveness.

Best Relics and Planar Ornaments

"Warrior Goddess of Sun and Thunder" is the perfect set for Hyacine in terms of relics. With two pieces, this set provides 6% SPD. When Hyacine or Ica heals teammates with four pieces equipped, it adds the "Gentle Rain" effect, which increases allies' CRIT DMG by 15% and gives Hyacine an extra SPD boost.

Get the "Giant Tree of Rapt Brooding" Planar Ornament set to go with this. It provides a 6% SPD bonus, and at 135 or 180 SPD (with higher bonuses at 180+), it boosts healing from Hyacine and Ica by 12% or 20%. Given her optimal SPD should be above 200 to trigger her Trace abilities, the 20% bonus is consistently achievable.

Recommended Stats to Focus On
When farming for relics and ornaments, prioritize:
●SPD: Improves healing and damage scaling, making it an essential component of her kit.
●HP: Increases her base healing power.
●Outgoing Healing: Enhances the overall healing effect.
●CRIT DMG: Unconventional for healers, but important due to Hyacine and Ica having high base CRIT Rate.
●Energy Regeneration Rate (ERR): Helps maintain Ultimate uptime for constant healing and buffs.

Balancing these stats is essential. High SPD is non-negotiable, but combining it with HP and healing stats while squeezing in CRIT DMG makes her build somewhat intricate, though rewarding.

Best Team Compositions for Hyacine
Hyacine thrives in teams focused on Max HP scaling, but her kit is flexible enough to work in most team setups.

Recommended Team Examples:

HP Synergy Team
Hyacine (Wind, Remembrance) + Castorice (Quantum, Remembrance) or Mydei (Imaginary) + Tribbie (Quantum, Harmony) + Ice Trailblazer (Ice, Remembrance)

General Hypercarry Team
Hyacine + Ice Trailblazer + Aglaea (Lightning, Remembrance) or Herta + Sunday (Imaginary, Harmony) or any Harmony buffer

Budget/F2P Team
Hyacine + Any DPS + Ice Trailblazer + Pela (Ice, Nihility) or Tingyun (Lightning, Harmony)

Hyacine fits well with high-HP scaling DPS like Blade or Tribbie, but she's equally viable with standard CRIT-based attackers or Break-focused characters such as Xueyi or Firefly. For optimal synergy, including a Harmony support like Ruan Mei or Harmony Trailblazer helps maximize her healing output.

Of course, you can buy Honkai: Star Rail account with many heroes on Z2U, so you can explore more Team Compositions suitable for Hyacine.

Trace Leveling Order
To maximize Hyacine's effectiveness, focus first on leveling Ica's skills through her Talent, followed by her Ultimate and then her Skill. Be sure to unlock all passive Traces to fully unlock her healing potential, while her Basic Attack should be the lowest upgrade priority.

Conclusion
Hyacine is a remarkably versatile healer with both offensive and defensive capabilities. With access to strong free-to-play gear and wide team flexibility, building her optimally is achievable for most players. While balancing her stats can be tricky early on, investing in SPD, healing, and CRIT DMG will make her a powerful anchor for nearly any team in Honkai: Star Rail.
