Who is Hyacine? Character Overview & Role
Version 3.3 brought us Hyacine, and honestly? She's not your typical healer. This 5★ Wind Remembrance character throws traditional sustain out the window with her memosprite mechanics. Her kit revolves around three core abilities: Love Over the Rainbow (Skill), We Who Fly Into Twilight (Ultimate), and Take Sky in Hand (Memosprite Talent).
What makes her special isn't just the healing—it's how she fundamentally changes team dynamics.
Pros and Cons
The Good Stuff:
- Highest damage output among sustain characters in 3.3 (and it's not even close)
- That A2 Trace gives guaranteed 100% CRIT Rate—yes, you read that right
- HP-scaling abilities that actually benefit from team HP consumption
- Built-in debuff cleansing through A4 Trace
The Reality Check:
- You absolutely need 200+ SPD investment for her A2 Trace to shine
- 140 Energy Ultimate cost means Energy Regeneration Rate becomes non-negotiable
Why Acheron Teams Are Going Crazy for Her
Here's where things get interesting. Hyacine's memosprite doesn't just heal—it generates vulnerability stacks that directly feed into Acheron's damage rotation. Her signature Light Cone takes this further with +36% enemy damage taken for 2 turns.
It's synergy that feels almost too good to be true.
Honkai Star Rail Hyacine recharge for stamina and pulls through BitTopup ensures you've got enough Stellar Jade for both Hyacine and her signature—competitive pricing with instant delivery that actually works.
Hyacine Kit & Trace Priority
Breaking Down Her Abilities
Love Over the Rainbow (Skill) summons memosprite Ica with some serious AoE healing: 4% Max HP +40 to your team, with Ica getting a bonus 5% +50. Simple, effective, reliable.
We Who Fly Into Twilight (Ultimate) is where the magic happens. It grants 'After Rain' state—+30% Max HP and +600 flat HP to allies for 3 turns. This isn't just healing; it's HP inflation that makes Ica's subsequent heals hit like trucks.
Take Sky in Hand (Talent) establishes Ica at 50% of Hyacine's Max HP. Each heal boosts Ica's damage by 40%, stacking up to 120% total. When allies take damage, Ica automatically heals for 2% Max HP +20, consuming 4% of her own HP in the process.
It's elegant design that rewards aggressive play.
Bonus Abilities That Matter
A2 Trace (Tempestuous Halt) gives +20% Max HP and +1% Outgoing Healing per SPD point above 200. Maximum 200% bonus. This is why speed matters so much.
A4 Trace (Stormy Caress) provides +50% Effect RES and cleanses one debuff when using Skill or Ultimate. Underrated utility that saves runs.
A6 Trace (Gloomy Grin) ensures 100% CRIT Rate for both Hyacine and Ica, plus +25% Outgoing Healing when allies drop below 50% HP. This trace alone justifies her 5-star status.
Trace Leveling Priority (Don't Mess This Up)
- Memosprite Talent first—damage scaling is everything
- Skill second—core healing and memosprite summoning
- Ultimate third—After Rain duration matters
- Memosprite Skill last—damage and utility
Major Traces: Gloomy Grin > Stormy Caress > Tempestuous Halt
Best Relics for Hyacine
The Clear Winner: Warrior Goddess
Warrior Goddess of Sun and Thunder (4-piece) isn't just good—it's perfect. The 2-piece gives +6% SPD, but the 4-piece effect is where it shines: Gentle Rain triggers after healing, providing +6% SPD and +15% ally CRIT DMG for 2 turns.
This set was basically designed for her kit.
If You're Still Farming: Mix 2-piece Sacerdos' Relived Ordeal with Messenger Traversing Hackerspace for pure SPD focus while you hunt for Warrior Goddess pieces.
Planar Ornaments: Speed is Life
Giant Tree of Rapt Brooding offers +6% SPD baseline, with ≥180 SPD granting +20% Outgoing Healing. It's the safe choice that works in every scenario.
Amphoreus, The Eternal Land (3.7) provides +8% CRIT Rate and +8% team SPD when memosprite is active. More aggressive, potentially higher ceiling.
Situational Options: Lushaka for Energy Regeneration Rate focus, Broken Keel for team CRIT DMG if you can hit 30%+ Effect RES.
Stat Priority (The Numbers That Actually Matter)
Main Stats:
- Body: Outgoing Healing > HP% (healing first, always)
- Feet: SPD > HP% (speed breakpoints are crucial)
- Sphere: HP% (no alternatives worth considering)
- Rope: Energy Regeneration Rate (140 energy cost demands it)
Substats: SPD > HP% > CRIT DMG > Effect RES
Endgame Targets: 5000+ HP, 200+ SPD, 130%+ CRIT DMG, 30%+ Effect RES
These aren't suggestions—they're requirements for optimal performance.
Best Light Cones for Hyacine
The Premium Options
Long May Rainbows Adorn the Sky (Signature S1) is absolutely broken. +30% SPD, consumes 2% ally HP for memosprite damage (500% of consumed HP), and memosprite Skills increase enemy damage taken by 36% for 2 turns.
There's no competition here.
To Evernight's Stars (S1) grants +60% Max HP and Noctis state (+60% DMG, ignore 30% DEF), plus +16 Energy when memosprite vanishes. Solid alternative if you missed her signature.
This Love, Forever (S1) offers +30% SPD with memosprite Skill providing +28% ally CRIT DMG. Good for speed-focused builds.
Budget-Friendly 4-Star Options
The Story's Next Page (S5) provides +32% Max HP and +24% Outgoing Healing for 1 turn after memosprite attacks. Reliable, accessible.
Victory In a Blink grants +24% CRIT DMG and +16% ally damage for 3 turns when memosprite appears.
Memory's Curtain Never Falls offers +12% SPD and +16% ally damage for 3 turns post-Skill.
Fast Honkai Star Rail top up Stellar Jade for Acheron team optimization through BitTopup provides reliable access to premium Light Cones—secure payment processing and 24/7 support that actually responds.
Hyacine Eidolons: Investment Reality Check
The Ones That Matter
E1: 'After Rain' Max HP effect increases by +50%, allies restore HP after attacking. Nice quality of life, not game-changing.
E2: Grants +30% Speed to allies whose HP drops for 2 turns. This is the big one—speed manipulation that changes team rotations entirely.
E6: When Ica is active, allies gain +20% All-Type RES PEN, Ica's Skill clears 12% damage tallies. Whale territory, but genuinely powerful.
Investment Advice (From Someone Who's Done the Math)
F2P Players: E0S1 beats E1S0 every single time. Her signature light cone is that important.
Moderate Spenders: E1 for HP-scaling teams, E2 if you're building around speed manipulation.
Whales: E6 delivers approximately 20% team DPS increase. Expensive, but the numbers don't lie.
Best Teams for Hyacine
The Acheron Dream Team
Core: Acheron (DPS), Jiaoqiu/Pela (Nihility), Sparkle/Bronya (Harmony), Hyacine (Sustain)
This isn't just synergy—it's symbiosis. Memosprite generates vulnerability stacks for Acheron's Ultimate charging while the signature Light Cone's +36% damage taken stacks multiplicatively with everything else.
I've seen this team clear Memory of Chaos cycles that shouldn't be possible.
Castorice Hypercarry
Setup: Castorice (DPS), Tribbie/Remembrance MC/Sunday (Support), Hyacine (Sustain)
Maximizes HP consumption mechanics. Castorice drains HP, Hyacine's auto-heals trigger constantly, damage scales through the roof.
HP-Scaling Compositions
Mydei Team: Mydei (DPS), Cyrene (SubDPS), Tribbie (Support), Hyacine (Sustain) Blade Revival: Blade (DPS), Sunday (Harmony), Tribbie (Support), Hyacine (Sustain)
Both leverage HP drain mechanics while Hyacine provides sustain and damage amplification. Blade teams, in particular, feel completely different with her.
Follow-Up Attack Synergy
FUA Core: Feixiao (DPS), Cipher/Hunt March 7th (SubDPS), Robin (Harmony), Hyacine (Sustain)
Speed manipulation enhances Follow-Up Attack frequency. Robin's energy sharing with reliable sustain creates incredibly smooth rotations.
Hyacine vs. Other Sustains (The Honest Comparison)
vs. Aventurine
Hyacine Wins: Higher personal damage, superior healing for HP-scaling teams, debuff cleansing, better Acheron integration.
Aventurine Wins: Shield-based protection, Follow-Up synergy, lower SPD requirements, easier to build.
Verdict: Different roles. Aventurine for shields, Hyacine for active healing and damage.
vs. Gallagher
Hyacine Wins: 5-star scaling, memosprite utility, cleanse capabilities, premium Light Cone access.
Gallagher Wins: Break effect synergy, lower investment requirements, simpler stat tuning, F2P accessibility.
Verdict: Gallagher's still viable, but Hyacine represents the future of sustain design.
vs. Huohuo
Hyacine Wins: Superior damage contribution, better action economy, vulnerability generation, modern kit design.
Huohuo Wins: Energy regeneration for the team, Ultimate cleanse, established build guides, lower SPD requirements.
Verdict: Huohuo's energy support is unique, but Hyacine does everything else better.

FAQ (The Questions Everyone's Asking)
Is Hyacine actually good for Acheron teams? Exceptional synergy. Memosprite generates vulnerability stacks, signature Light Cone increases enemy damage taken by 36%. It's not just good—it's optimal.
What SPD does Hyacine actually need? Minimum 180 SPD for Giant Tree breakpoint, but you really want 200+ SPD for A2 Trace benefits. Don't compromise on this.
Is her signature Light Cone worth the pulls? Yes. The HP consumption mechanics and +36% enemy damage taken have no comparable alternatives. It's that important.
Can Hyacine solo sustain Memory of Chaos? Absolutely, when built with 200+ SPD, 5000+ HP, and appropriate Energy Regeneration Rate. I've tested this extensively.
E1 Hyacine or signature Light Cone first? E0S1 provides more value than E1S0 in almost every scenario, especially for Acheron teams. Signature first, always.
Does Hyacine need Effect Hit Rate? No. Debuff effects come from memosprite abilities and Light Cone effects. Focus on SPD, HP, and Energy Regeneration Rate instead.
