Honkai Star Rail Hyacine Build Guide: Light Cones, Relics, Teams, Trace Priority, Materials

Hyacine is a Wind Remembrance sustain whose kit revolves around Little Ica, Max HP scaling, team healing, and high Speed conversion. She can make difficult stages feel cleaner because she fixes survival while still contributing through a memosprite loop.

Her kit text points to healing, debuff removal, Max HP increases, and a Speed threshold that rewards pushing past 200 SPD. She wants enough Speed to drive the loop, enough HP to strengthen healing, and enough Effect RES to stay online.

Quick answer: Build Hyacine for Speed and HP first. Aim for reliable healing, debuff removal, and Little Ica uptime before damage. She is a strong pull when your teams die, get controlled, or need a sustain that still fits Remembrance tempo.

Hyacine Overview And Role

Field	Value	Build meaning
Hyacine	5-Star Wind Remembrance	A Wind Remembrance sustain whose value is healing plus memosprite tempo.
Faction	Amphoreus	Her story context is secondary; the build is driven by HP, Speed, and Little Ica uptime.
Role	Healer / cleanser / memosprite sustain	She protects the team while Little Ica keeps contributing to the field state.
Best reader	Players choosing between damage pulls and sustain comfort	Most useful when survival or control effects are the reason clears fail.

Hyacine Skills And Kit Mechanics

Hyacine uses Skill and Ultimate to summon or support Little Ica while healing the party. Her traces reward very high Speed, and her kit includes debuff removal, which is valuable in long endgame fights.

Little Ica is the center

Skill and Ultimate keep the memosprite present, so the build should support uptime and not just one big heal.

Speed becomes output

Tempestuous Halt rewards Speed above 200 by adding HP and Outgoing Healing, so Speed is not only turn comfort.

Cleanse matters

Debuff removal on Skill and Ultimate makes her more than raw healing in control-heavy stages.

Hyacine Skill And Trace Priority

Level the parts that keep the rotation alive before polishing the lowest-impact action. If resources are tight, stop after the core loop works and return later for minor traces.

Trace	Priority	What it does in practice
We Who Fly Into Twilight	Highest	Ultimate [Support] Summons memosprite Little Ica, restores HP equal to 5% of Hyacine's Max HP plus 50 for all allies aside from Little Ica, and restores HP equal to 6% of Hyacine's Max HP plus 60 for Little Ica. Hyacine enters the
Love Over the Rainbow	Highest	Skill [Restore] Summons memosprite Little Ica, restores HP equal to 4% of Hyacine's Max HP plus 40 for all allies aside from Little Ica, and restores HP equal to 5% of Hyacine's Max HP plus 50 for Little Ica.
First Light Heals the World	High	Talent [Enhance] The memosprite Little Ica initially has Max HP equal to 50% of Hyacine's Max HP. When Hyacine or Little Ica provides healing, increases Little Ica's DMG dealt by 40% for 2 turn(s). Stacks up to 3 time(s).
Tempestuous Halt	High	When Hyacine's SPD exceeds 200, increases her and Little Ica's Max HP by 20%. Then, for every 1 excess SPD, increases Hyacine's and Little Ica's Outgoing Healing by 1%. Up to a max of 200 excess SPD can be taken into account for t
Stormy Caress	High	Increases Hyacine's Effect RES by 50%. When using Skill and Ultimate, dispels 1 debuff(s) from all ally targets.
When Breeze Kisses Cirrus	Low	Basic ATK [Single Target] Toughness Reduction: 10 Deals Wind DMG equal to 25% of Hyacine's Max HP to a designated enemy target.

Best Hyacine Light Cones

Hyacine's Light Cone choice should make sustain more reliable. The best option is the one that keeps Little Ica, healing, cleanse, and high-Speed play from falling behind the enemy turn cycle.

Light Cone tier	When to use it	Planning note
Signature or sustain-focused Remembrance cone	Best if it improves HP, healing, Energy, or Little Ica uptime.	Prioritize function over screenshot damage.
Energy comfort cone	Use when Ultimate arrives too late for long fights or debuff-heavy stages.	More frequent emergency healing can be worth more than higher peak HP.
HP / Effect RES cone	Use when Hyacine is being controlled or defeated before stabilizing the team.	Good for accounts that lose to mechanics rather than raw damage checks.
Accessible Path cone	Use while testing Speed and healing breakpoints.	A correct-role fallback is safer than forcing a mismatched premium cone.

Best Hyacine Relics And Stats

Build area	Recommended direction	Why
Main stats	Outgoing Healing or HP body, Speed boots, HP orb, Energy/HP rope	Choose Energy if Ultimate uptime is the problem; choose HP when healing size is the bottleneck.
Substats	Speed toward threshold, HP%, Effect RES, then defensive rolls	She must act quickly and avoid control effects to keep the team stable.
Relic direction	Speed, healing, HP, and support utility sets	Do not build her like a pure DPS just because Little Ica can deal damage.
Trace order	Ultimate and Skill first, then Talent and Speed/healing traces	The healing loop has to work before personal damage matters.

Hyacine Teams

Hyacine fits teams that want safety without abandoning action rhythm. She is especially attractive when your main carry loses turns to debuffs or needs a sustain who can keep pace.

Team shell	Example teammates	Why it works
Remembrance shell	Hyacine Robin • Summeretto Castorice Trailblazer: Remembrance	Multiple memosprite/action pieces benefit from a sustain that understands the same rhythm.
Hypercarry comfort	Hyacine Sunday Ruan Mei Phainon	Hyacine keeps the carry alive while supports invest in damage and turn quality.
Follow-up safety	Hyacine Aventurine Robin Topaz & Numby	Useful when the team wants off-turn pressure but needs extra healing/cleanse comfort.
Budget sustain slot	Hyacine Qingque Gallagher Asta	Use her to stabilize a cheaper roster while you build a second team.

Hyacine Rotation And Gameplay

Use Technique or opening setup when available to start with safer HP.
Skill early if Little Ica is absent or the team needs immediate healing.
Hold Ultimate for teamwide recovery, debuff pressure, or Little Ica uptime.
Keep Hyacine fast enough that healing arrives before emergencies become resets.
Refresh buffs and sustain before the carry damage window.

Hyacine Gameplay Preview

The key visual cue is Little Ica's presence in the sustain loop. Keep the displayed rotation short, readable, and focused on healing cadence.

Hyacine Materials And Farming Priority

Hyacine's farming order should make her sustain job reliable before improving side damage. If she cannot cleanse or heal on time, the rest of the build is noise.

Farming layer	Priority	Stop point
Skill and Ultimate traces	Highest	These are the core healing, cleanse, and Little Ica uptime tools.
Talent and Speed/healing traces	High	Raise them once the basic sustain loop is stable.
Character and Light Cone levels	High	HP and base stats directly affect survival comfort.
Speed boots and HP pieces	Medium-high	Secure her Speed/HP foundation before farming prettier substats.
Personal damage rolls	Late polish	Treat damage as bonus value, not the reason to delay sustain upgrades.

Hyacine Eidolons And Pull Advice

For most players, judge Hyacine at C0 first. Eidolons are worth discussing only after the base kit solves a real team problem.

Upgrade	Value	What changes
E1: Cradle the Candle of Night	First premium checkpoint	When Hyacine is in the "After Rain" state, additionally increases the Max HP of all ally targets by 50%, and immediately restores HP equal to 8% of Hyacine's Max HP after using an attack.
E2: Come Sit in My Courtyard	Strong if you already main the unit	When any ally target's HP decreases, this unit's SPD increases by 30% for 2 turn(s).
E3: Depart, Unto the Sun!	Trace-level upgrade	Ultimate Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10. Memosprite Skill Lv. +1, up to a maximum of Lv. 10.
E4: Sunlit Amber, Yours to Keep	Specialist upgrade	The "Tempestuous Halt" Trace is enhanced. For every 1 of SPD exceeded, additionally increases Hyacine and Little Ica's CRIT DMG by 2%.
E5: Twilight Drapes the Tide	Trace-level upgrade	Skill Lv. +2, up to a maximum of Lv. 15. Talent Lv. +2, up to a maximum of Lv. 15. Memosprite Talent Lv. +1, up to a maximum of Lv. 10.
E6: O Sky, Heed My Plea	Whale ceiling	Little Ica uses Memosprite Skill and changes the amount of Healing tally cleared to 12%. When Little Ica is on the field, increases all ally targets' All-Type RES PEN by 20%.

Hyacine is valuable when survival is the bottleneck. If your account already has premium sustain and clears safely, she becomes a comfort or archetype pull instead of a must-pull.

Player type	Recommendation	Reason
New account	Strong if you lack sustain	A reliable healer/cleanser can unlock more content than another DPS.
Returning account	Pull for comfort	Great when older teams die to newer debuffs or long fights.
Veteran account	Pull for Remembrance/sustain synergy	Veterans should compare her against existing sustain comfort and future memosprite plans.
Light Cone/Eidolons	Luxury after stability	Her base role matters first; upgrades are for comfort and ceiling.

Common Hyacine Mistakes

Ignoring Speed

Her high-Speed trace turns Speed into healing value, not just turn order.

Skipping cleanse value

Debuff removal is part of why she stabilizes hard fights.

Overbuilding damage

Little Ica damage is a bonus; sustain uptime comes first.

Pulling despite solved sustain

If you already survive easily, compare her against your next damage or support need.

Hyacine FAQ

Is Hyacine worth pulling?

Yes if you need sustain, cleanse, or a Remembrance-friendly healer. She is less urgent if your defensive slots are already excellent.

What stats does Hyacine want?

Speed, HP, healing consistency, and Effect RES. Damage is secondary.

Why is 200 SPD mentioned?

Her trace rewards Speed above 200 with Max HP and Outgoing Healing value, so Speed can directly improve her sustain output.

Does Hyacine replace every healer?

No. She is strongest where cleanse, speed, and memosprite tempo matter. Other sustains can still be better for specific teams.

Should beginners pull Hyacine?

A beginner without strong sustain can value her highly because stable clears speed up progression.

Hyacine Conclusion

Hyacine is a comfort-first Remembrance sustain. Build Speed and HP, keep Little Ica active, and use her when survival is what prevents your team from showing its damage.
