HSR Hyacine Character Information
Her full name is Hyacinthia, a swift and versatile Remembrance healer hailing from the Twilight Courtyard in Amphoreus. Here is a quick overview of her basic profile.
 | Rarity | ★★★★★ |
| Combat Type | Wind | |
| Combat Path | The Remembrance | |
| Combat Roles | Sustain / Sub-DPS High SPD & 100% CRIT Focus | |
| Faction | Amphoreus / Chrysos Heirs | |
| How to Obtain | A Rainbow onto Twilight Warp |
Known as the "Healer of the Sky" and "Eye of Twilight," she carries her ancestors' will to restore the boundary between dusk and dawn.
In battle, as a member of the Skyfolk, she summons her Memosprite "Little Ica." With a built-in 100% CRIT Rate and immense Speed, Hyacine provides AoE healing, teamwide cleanses, and Max HP buffs, while dealing impressive sub-DPS damage — the harder she heals, the harder she hits.
Is Hyacine Worth Pulling?
As a limited 5-star sustain, Hyacine is an exceptional pick. Her ability to guarantee multiple turns per wave via massive SPD stats makes her a comfortable healer who doubles as a potent Sub-DPS.
Tier Rating | T0 |
Strengths |

Weaknesses |
|
If you have Castorice, Hyacine is a must-pull due to her HP consumption mechanics generating Newbuds. She is also a top-tier sustain for Acheron and Blade, especially with her signature Light Cone applying Vulnerability.
Important Note
- Character overall tier ratings are intended merely as a reference scale. Support and Sustain units often have higher longevity in the meta.
- In gacha games, personal preference is paramount; pull recommendations evaluate mechanics and strength, but should not be your sole basis for pulling.
Hyacine's Best Builds (At a Glance)
Hyacine is an extremely fast and effective Remembrance healer that can heal all party members and deal decent damage. Her high SPD stat allows her to have at least two turns per wave when built properly. Here is a quick overview of her optimal setup.
Best Light Cone | Long May Rainbows Adorn the Sky |
Best Relics | Warrior Goddess of Sun and Thunder (4-Pc) |
Best Ornaments | Giant Tree of Rapt Brooding (2-Pc) |
Main Stats Priority | Body: Outgoing Healing Feet: SPD Sphere: HP% Rope: Energy Regeneration Rate |
Sub Stats Priority | SPD (Until 200+) > HP% > CRIT DMG > Flat HP |
Build Analysis: This base build requires a high SPD investment from the Light Cone, Relics, and sub-stats. Hyacine will need more than 200 SPD during combat to fully utilize her "Tempestuous Halt" Bonus Ability.
Since her kit scales off HP and she has a built-in 100% CRIT Rate, reaching the SPD threshold should always be the first priority. Once met, focus on balancing HP% (aiming for 4500+) and CRIT DMG to maximize her sub-DPS potential.
Hyacine's Best Relics and Ornaments
There's no doubt that the Warrior Goddess of Sun and Thunder relic set is the prime choice. It fully exploits its potential to enhance her combat performance, aligning seamlessly with Hyacine's healing and SPD mechanics.
Relic / Ornament | Icon | Rating & Merits |
| Warrior Goddess of Sun and Thunder (x4) |  | ★★★★★ - Best Hyacine's best-in-slot relic set. It provides SPD and increases the party's CRIT DMG whenever she or her memosprite provides healing. |
| Sacerdos' Relived Ordeal (x2) Messenger Traversing Hackerspace (x2) |   | ★★★★☆ - 2nd Best You can use any 2pc Relic that provides a SPD increase to help reach the 200 SPD threshold for her Bonus Ability. |
| Giant Tree of Rapt Brooding |  | ★★★★★ - Best This is Hyacine's best ornament since it increases her SPD and provides more healing depending on her SPD stat. |
| Broken Keel |  | ★★★★☆ - 2nd Best Broken Keel can be used to increase the party's CRIT DMG. You don't need to build Effect RES since her Bonus Ability provides enough. |
| Amphoreus, The Eternal Land |  | ★★★☆☆ - 3rd Best Can be used to increase the party's SPD simply by having Little Ica active on the field. |
Relic List & Guide Analysis: Getting a full 4-piece Warrior Goddess of Sun and Thunder is highly recommended because the SPD and team-wide CRIT DMG buffs are unparalleled for her role.
For Ornaments, Giant Tree of Rapt Brooding is a must-have. When farming, remember that since Hyacine is guaranteed to land critical hits via her "Gloomy Grin" trace, CRIT Rate is a dead stat. Focus entirely on pushing her SPD past 200, then stack HP% and CRIT DMG.
Hyacine's Best Light Cones
The right Light Cone unlocks Hyacine's full potential. Since her kit revolves around high SPD and HP scaling, you’ll want options that lean into her frequent off-turn actions. Here are our top picks.
Light Cone | Rating & Why We Recommend It |
 Long May Rainbows Adorn the Sky | ★★★★★ - Best Hyacine's signature Light Cone. It provides a huge SPD increase and increases the damage taken by enemies. It also triggers team-wide HP consumption, unleashing massive Additional DMG through Little Ica. |
 Memory's Curtain Never Falls | ★★★★☆ - Great A more accessible Light Cone that provides SPD and increases the party's DMG when Hyacine uses her Skill. Since she skills frequently, the buff uptime is nearly 100%. |
 This Love, Forever | ★★★★☆ - Great While Hyacine can't access the Blank buff, she can still use this Light Cone for its massive SPD increase and the Verse buff to support the team. |
 Victory In a Blink | ★★★☆☆ - Good An accessible Light Cone that increases Hyacine's CRIT DMG and buffs the party's DMG when she uses her Skill. The CRIT DMG buff is highly usable since Hyacine can always Crit. |
Long May Rainbows Adorn the Sky is her best-in-slot, as it ties her HP-drain mechanic directly to Vulnerability debuffs — a great fit for teams running Acheron or Blade.
If you're skipping her signature, Memory's Curtain Never Falls is a solid F2P option that keeps her running smoothly while still boosting team damage.
Hyacine's Best Teams
Hyacine is a versatile Remembrance healer who acts as a semi-sustain, semi-support, and semi-DPS. Mechanically, she pairs best with HP-scaling DPS units, high-frequency AoE attackers, and characters who do not overly consume Skill Points.
She heavily favors Aura or Debuff supports, as her extreme SPD (200+) will burn through traditional turn-based buffs too quickly. While she is the definitive best sustain for Castorice, bringing her Eidolon 1 (E1) or Signature Light Cone is highly recommended if you plan to use her in other generalist teams.
1. Castorice Premium Core (Best Team)
Main DPS | Sub-DPS | Support | Sustain |
 Castorice |  Evernight |  Cyrene |  Hyacine |
Team Analysis: Hyacine's mechanics are practically tailor-made for Castorice. She significantly speeds up Castorice's energy regeneration and provides essential Max HP buffs. Cyrene acts as the team's accelerator, enhancing energy flow and speeding up ally turns. By timing her skills, she turns Castorice’s damage windows into massive bursts, which seamlessly triggers Hyacine’s healing. Evernight provides continuous Memosprite-based buffs, allowing the entire team to operate at peak efficiency.
2. HP-Scaling Resonance (Blade / Mydei / Castorice)
Main DPS | Support | Support | Sustain |
 Blade / Mydei |  Tribbie |  Trailblazer (Ice) | Hyacine |
Team Analysis: Mydei requires a significant amount of healing to maintain his HP to ensure his energy recharge from HP consumption. Hyacine's sheer speed guarantees consistent healing uptime. If using Blade, Hyacine's signature Light Cone is critical; its team-wide HP drain frequently triggers Blade's follow-up attacks. Tribbie serves as a rare aura buffer who perfectly complements HP-scaling allies, while the Ice Trailblazer provides Action Advances, CRIT DMG, and an extra Memosprite entity.
3. Acheron Ultimate Burst
Main DPS | Support (Nihility) | Support | Sustain |
 Acheron |  Jiaoqiu |  Pela / Sparkle | Hyacine |
Team Analysis: Although Hyacine natively lacks debuffs, equipping her with Long May Rainbows Adorn the Sky allows her Memosprite, Little Ica, to apply Vulnerability. Combined with her naturally absurd SPD, she generates Slashed Dream stacks for Acheron faster than almost any other sustain in the game, turning her into a premium enabler for this composition.
4. Mono-Carry Setup (Requires Eidolon 6)
Main DPS | Support | Support | Support |
Hyacine (E6) |  Sunday | Tribbie | Trailblazer (Ice) |
Team Analysis: For players who invest heavily, an E6 Hyacine can become a devastating Main DPS. Because she has a built-in 100% CRIT Rate, Sunday's massive buffs (excluding CRIT Rate) are perfectly absorbed. Though Sunday’s Action Advance doesn't directly pull Memosprites, dragging Hyacine forward forces Little Ica to act immediately after her anyway. Tribbie and the Ice Trailblazer round out the team with irreplaceable Aura buffs, CRIT DMG, and RES PEN.
Other Notable Synergies
Character | Synergy Explanation |
 Feixiao | Hyacine's Memosprite operates as an independent entity on the action bar. These high-frequency off-turn attacks rapidly generate Flying Aureus stacks for Feixiao. |
 The Herta | Little Ica unleashes AoE strikes across all enemy targets. This widespread damage is extremely beneficial for battery purposes, helping The Herta restore energy consistently. |
Hyacine's Trace Priority
Upgrading Hyacine's traces in the proper sequence is essential. Her core value lies in her massive healing output and Max HP buffs, followed by her Memosprite's sub-DPS potential. You should prioritize her sustain abilities first.
Priority | Trace Name & Level Target |
| Highest (Sustain) | Memosprite Talent (Lv.6) = Ultimate (Lv.10) = Skill (Lv.10) Max these out first to guarantee your team's survival and maximize the HP buffs. |
| High (Damage) | Memosprite Skill (Lv.6) = Talent (Lv.10) Level these next to significantly increase Little Ica's damage output based on your total healing. |
| Low (Filler) | Basic ATK (Lv.1) Can be left at level 1 since Hyacine will use her Skill almost every turn. |
Hyacine's Eidolons
Hyacine is a complete character at E0, but her Eidolons provide massive quality-of-life improvements, numerical boosts, and eventually turn her into a top-tier damage dealer at E6.
Eidolon | Effect & Analysis |
 E1 | Cradle the Candle of Night: When in the "After Rain" state, additionally increases the Max HP of all allies by 50%, and immediately restores HP equal to 8% of Hyacine's Max HP after using an attack. Analysis: Best stopping point for spenders. It provides an absolutely massive HP multiplier and adds a highly frequent auto-healing mechanic, drastically raising the damage ceiling of HP-scaling teams. |
 E2 | Come Sit in My Courtyard: When any ally target's HP decreases, this unit's SPD increases by 30% for 2 turns. Analysis: Reduces her heavy SPD relic requirements. It triggers frequently via enemy attacks or HP-drain mechanics (like Blade, Castorice, or her Signature LC). |
 E3 | Depart, Unto the Sun!: Ultimate Lv. +2, Basic ATK Lv. +1, Memosprite Skill Lv. +1. |
 E4 | Sunlit Amber, Yours to Keep: Enhances "Tempestuous Halt". For every 1 excess SPD, additionally increases Hyacine and Little Ica's CRIT DMG by 2%. Analysis: Transforms her into a true Sub-DPS. Since she has a guaranteed 100% CRIT Rate, converting excess SPD directly into CRIT DMG massively amplifies Little Ica's burst output. |
 E5 | Twilight Drapes the Tide: Skill Lv. +2, Talent Lv. +2, Memosprite Talent Lv. +1. |
 E6 | O Sky, Heed My Plea: Little Ica's Memosprite Skill only clears 12% of the Healing tally (down from 50%). When Little Ica is on the field, increases all allies' All-Type RES PEN by 20%. Analysis: The ultimate pinnacle of her kit. Giving the entire team 20% RES PEN is an invaluable Aura. Moreover, only clearing 12% of the healing tally means Little Ica's damage will snowball uncontrollably the longer the battle lasts. |
Hyacine's Abilities
Her abilities provide massive AoE healing while setting up her Memosprite for continuous off-turn damage.
Icon | Ability Name & Core Mechanic |
 | Love Over the Rainbow (Skill) Summons Little Ica (if not present) and restores HP to all allies based on Hyacine's Max HP. Note: If Little Ica is already on the field, using this will not trigger the "first summon" energy gain, but will consistently heal the team. |
 | We Who Fly Into Twilight (Ultimate) Heals the entire team and grants Hyacine the "After Rain" state for 3 turns. While active, the Max HP of all allies increases massively (30% + 600 at Lv.10). This state is applied before the healing, meaning the ultimate's heal scales off the newly buffed HP limit. |
 | First Light Heals the World (Talent) Whenever Hyacine or Little Ica provides healing, Little Ica's DMG dealt increases by 80% for 2 turns (stackable up to 3 times). Given her high frequency of healing, this 240% DMG buff is effectively permanent. |
 | Gloomy Grin (Bonus Ability) Increases Hyacine and Little Ica's CRIT Rate by 100%. Also increases Outgoing Healing by 25% when targeting allies below 50% HP. This guarantees her Memosprite attacks will always crit, allowing you to ignore CRIT Rate relics. |
 | Stormy Caress (Bonus Ability) Increases her Effect RES by 50%. Her Skill and Ultimate will cleanse 1 debuff from all allies. Thanks to her extreme SPD, crowd control on her teammates is almost never a problem. |
 | Tempestuous Halt (Bonus Ability) When her SPD exceeds 200, Max HP increases by 20%. Every 1 excess SPD converts into 1% Outgoing Healing (up to 200%). This is the core reason you must push her SPD as high as possible. |
Little Ica (Memosprite) Overview
Little Ica is an independent Memosprite entity that inherits 50% of Hyacine's out-of-combat Max HP. It acts as the team's autonomous safety net and Hyacine's primary source of damage.
Icon | Memosprite Mechanic |
 | Take Sky In Hand (Memosprite Talent) Little Ica has 0 SPD, does not appear on the Action Order, and is completely immune to debuffs. When any ally loses HP, Little Ica consumes 4% of its own HP to immediately heal that ally. While Hyacine has the "After Rain" state, Little Ica gains an immediate Extra Turn right after Hyacine uses an ability, triggering its AoE attack. During this state, its reactive heals also become team-wide AoE heals. |
 | Rainclouds, Time to Go! (Memosprite Skill) An AoE Wind attack. The damage multiplier is uniquely based on the total tally of healing performed by Hyacine and Little Ica during the battle. After attacking, it clears 50% of the recorded tally (or 12% if at E6), allowing the remaining healing to roll over and snowball the damage of subsequent attacks. |
Hyacine Upgrade Materials
Planning ahead for Hyacine? To maximize her HP-scaling healing, ensure her Memosprite "Little Ica" acts swiftly, and properly support units like Castorice or Acheron, you'll need to fully build her. Hyacine uses the Fear-Stomped Flesh material series which you can get from farming Titankin enemies in Amphoreus.
She also uses A Glass of the Besotted Era for her Stagnant Shadow material. For her Trace upgrades, Hyacine requires the Bija of Consciousness series and the Lost Echo of the Shared Wish Echoes of War materials. Read on for the complete breakdown!

Summary: The Verdict on Hyacine
Hyacine is a high-ceiling Sustain and Sub-DPS hybrid who easily earns her T0-tier placement. Her gameplay loop is approachable for general survival, but mastering her team-wide HP drain, Memosprite (Little Ica) damage snowballing, and extreme 200+ SPD requirement adds genuine depth.
She rewards investment at every level — E0 is already highly competitive, E1 and E6 are massive power spikes, and her signature Light Cone, Long May Rainbows Adorn the Sky, remains the single largest upgrade you can give her.
Her main weakness is her strict stat thresholds and Light Cone dependency. The drop-off from her signature to alternatives is noticeable, as she loses the Vulnerability debuff and active HP drain. Memory's Curtain Never Falls is a workable F2P option, but budget players will feel the gap in specialized teams like Acheron or Blade comps.
For Ver. 4.1, pull priority is straightforward: pair her with Castorice for the ultimate HP-scaling core, and E0S1 is the recommended stopping point for most players — competitive, efficient, and complete.
Hyacine's versatile kit opens up strong team options at any investment level. Planning to pull her? Top up Honkai: Star Rail at GamsGo and get ready for her banner. Happy gaming!
FAQ
Does Hyacine need CRIT Rate Relics?
No. Her Bonus Ability, Gloomy Grin, grants her and Little Ica a fixed 100% CRIT Rate. Any CRIT Rate stats on her relics are completely wasted. Focus entirely on SPD, HP%, and CRIT DMG.
How does Little Ica deal damage?
Little Ica's AoE attack (Memosprite Skill) scales off the total accumulated healing performed by both Hyacine and Little Ica during the battle. After attacking, it clears 50% of this tally (or 12% at E6), allowing the remaining healing to roll over and increase the damage of subsequent attacks.
What happens if Little Ica is crowd-controlled?
Little Ica is 100% immune to all debuffs and does not appear on the Action Order. Furthermore, Hyacine's high Effect RES and party-wide cleanse abilities ensure the team remains safe from crowd control.
