Hyacine Build HSR 2026: Best Relics, Light Cones, Speed and Teams

Reviewed: October 9, 2026. Build assumptions: E0 Hyacine, Level 80, unlocked major Bonus Abilities and all SPD minor Traces. Limited Light Cones are considered at S1; Herta Store equipment is compared at the stated Superimposition.

The strongest starting point for a Hyacine build in HSR is a fast healer with reliable Ultimate uptime. Her healing also feeds Little Ica’s damage, so the right build improves survival, team support and personal damage together. This guide explains which stats to fix first, how to reach her Speed condition, and when a cheaper setup is already enough.

1. ⚡ Quick Answer: Best Hyacine Build

Build part	Default recommendation
Role	5★ Wind / Remembrance healer, HP support and Little Ica damage
Cavern Relics	Warrior Goddess of Sun and Thunder ×4
Planar Ornaments	Giant Tree of Rapt Brooding ×2
Main stats	Outgoing Healing / SPD / HP% / Energy Regeneration Rate
SPD goal	201+ as a practical displayed target; verify the actual in-combat condition
Substats	SPD to the target → HP% → CRIT DMG; Effect RES for comfort
Signature / F2P	Long May Rainbows Adorn the Sky S1 / Memory’s Curtain Never Falls S5

2. 🪽 How Hyacine and Little Ica Work

2.1 ❤️ Healing Is Part of Her Damage Engine

Hyacine supplies active team healing through Skill and Ultimate. Little Ica adds reactive healing after allies lose HP and converts the recorded healing tally into AoE Wind damage. This makes HP, Outgoing Healing and frequent useful actions valuable even when you care about damage.

Little Ica has 0 SPD and does not take normal turns on the Action Order. Raising Hyacine’s SPD helps her act more often; during After Rain, those abilities also trigger Ica’s extra attacks. Trying to speed-tune Ica like an ordinary summon misses how the kit works.

2.2 🔓 Three Bonus Abilities That Change the Build

Bonus Ability	Released effect to build around	Practical consequence
Gloomy Grin	Adds 100% CRIT Rate to Hyacine and Little Ica; improves healing on targets at or below 50% HP.	CRIT Rate farming has little value once this is unlocked.
Stormy Caress	Adds 50% Effect RES; Skill and Ultimate remove one debuff from all ally targets.	Cleanse requires an active Skill or Ultimate.
Tempestuous Halt	When SPD exceeds 200, adds 20% Max HP to Hyacine and Ica; each excess SPD adds 1% Outgoing Healing, counting up to 200 excess SPD.	Cross the condition, then take efficient additional SPD rolls.

3. 🧩 Best Hyacine Relics and Planar Ornaments

3.1 🌦️ Warrior Goddess Is the Default Cavern Set

Warrior Goddess of Sun and Thunder gives 6% SPD from its two-piece bonus. Healing another ally with the wearer or their memosprite activates Gentle Rain: another 6% SPD and 15% team CRIT DMG for two turns. The effect does not stack. Hyacine’s normal healing pattern fits this trigger well.

Relic setup	When I would use it	Trade-off
Warrior Goddess ×4	Default dedicated Hyacine build.	Keep Gentle Rain active for the extra SPD and team buff.
Two different 2-piece SPD sets	Strong interim pieces from Warrior Goddess, Messenger Traversing Hackerspace or Sacerdos’ Relived Ordeal.	Two 6% bonuses provide 12% SPD, but lose Warrior Goddess’s team CRIT DMG.
World-Remaking Deliverer ×4	An alternative if its HP/team damage effects suit the roster and the build already meets its SPD target.	Provides no SPD. Compare the whole setup before replacing the default set.

3.2 🌌 Giant Tree vs Amphoreus

Planar set	Relevant effect	Best use case
Giant Tree of Rapt Brooding	6% SPD; 12% Outgoing Healing at 135 SPD or 20% at 180 SPD, for wearer and memosprite.	Default healing and Little Ica setup. The two healing tiers do not add together.
Amphoreus, The Eternal Land	8% CRIT Rate; 8% SPD for all allies while the wearer’s memosprite is present. Same effect does not stack.	Team Speed support when healing is sufficient and another teammate is not already supplying the same set buff.

Amphoreus’s CRIT Rate is largely redundant for Hyacine after Gloomy Grin. Choose it for the team SPD effect, then recheck everyone’s action order. Giant Tree is the cleaner starting point when healing throughput matters. The Planar Ornament farming guide covers how to obtain the Sphere and Rope without treating every upgrade as a new Cavern farm.

4. ⚡ Hyacine Stats and Speed Targets

4.1 📊 Main Stats and Useful Benchmarks

Slot / stat	Recommended starting point	Why
Body	Outgoing Healing; HP% is a temporary fallback.	Supports recovery and the healing tally.
Boots	SPD	Builds action frequency and the key Speed condition.
Sphere	HP%	Improves HP-based healing and survivability.
Rope	Energy Regeneration Rate	Supports the 140-Energy Ultimate and After Rain uptime.
HP	Roughly 4,300–5,000+ outside combat at Level 80.	A reference range, not a compulsory minimum or an in-combat buffed target.
CRIT DMG	Around 100–120%+ when core needs are solved.	Useful for Ica damage; avoid sacrificing the healing core just for this number.
Effect RES	68 percentage points from unlocked Bonus Ability/minor Traces.	Additional rolls are comfort investment after SPD and sustain.

For F2P players, the first question is whether the party stays alive and After Rain returns on time. A better ERR Rope or SPD piece often solves more than a prettier CRIT DMG screenshot. Keep CRIT Rate, ATK and Effect Hit Rate low on the priority list for this default build.

4.2 🎯 Is 180, 200 or 201+ SPD the Right Goal?

In-combat SPD	What it means	Next step
Below 180	The kit still works; Giant Tree may only meet its lower healing tier.	Finish main stats, levels and SPD Traces.
180 to 200	Giant Tree reaches its stronger healing tier. Exactly 200 does not satisfy “exceeds 200”.	Work toward reliably exceeding 200.
More than 200	Tempestuous Halt’s HP increase activates and excess SPD improves healing.	Use 201+ displayed as a practical margin, then verify the live stats/effect.
Higher SPD	More actions and more excess-SPD healing, subject to rotation and stat trade-offs.	Compare actual team results; there is no universal 300-SPD requirement.

4.3 🧮 How Much SPD Must Your Relics Supply?

The following worked example uses 110 base SPD, 14 flat SPD from minor Traces, displayed +25 SPD boots, Giant Tree’s 6% and Warrior Goddess’s full 12% with Gentle Rain active. It excludes teammates, Eidolons, other buffs and relic substats. Percentage bonuses apply to 110 base SPD; they do not multiply the +14 Trace SPD or boots.

Approximate SPD = 110 × (1 + applicable SPD%) + 14 + 25 + flat SPD substats.

Light Cone assumption	SPD before substats, Gentle Rain active	Extra flat SPD for about 201
Signature S1 — 18% SPD	188.6	12.4
Memory’s Curtain Never Falls S5 — 12% SPD	182.0	19.0
Memory’s Curtain Never Falls S1 — 6% SPD	175.4	25.6
No SPD Light Cone bonus	168.8	32.2

These are planning estimates from displayed inputs, not hidden-decimal optimizer outputs. Before Gentle Rain activates, subtract approximately 6.6 SPD. That opening difference matters if your plan needs the condition immediately. For example, +20 flat SPD substats with Memory S5 gives about 202 SPD after Gentle Rain, but only 195.4 before it.

For the wider action-value system behind these numbers, the Speed breakpoints guide explains how turns and cycle thresholds differ from a character-specific Trace condition.

5. 💿 Best Hyacine Light Cones

Light Cone	What it provides	My recommendation
Long May Rainbows Adorn the Sky S1	18% SPD; controlled ally HP consumption, extra memosprite damage and an enemy damage-taken debuff.	Default signature choice for players investing in her teams.
Memory’s Curtain Never Falls S5	12% SPD; 16% team DMG after Skill for three turns.	Default F2P target from Herta’s Store; it is a 5★ cone.
The Story’s Next Page	HP% and a healing bonus after memosprite attacks; no SPD.	Healing-focused four-star fallback when already owned.
Victory In a Blink	CRIT DMG and a conditional team DMG effect through an ally-targeting memosprite ability; no SPD.	Accessible interim option; read its trigger rather than assuming every Ica attack grants the buff.

5.1 🌈 Signature vs Herta Store: What Changes?

At S1, the signature consumes 1% of allies’ current HP after Hyacine uses Basic ATK, Skill or Ultimate. Ica’s next attack gains an extra damage instance linked to that consumed HP. Its Memosprite Skill also applies an 18% enemy damage-taken increase for two turns; the same effect does not stack.

Those HP-loss events and the debuff are Light Cone effects, not something every E0 Hyacine automatically supplies. Memory S5 instead provides SPD and team damage after Skill. It supports the core build well, but does not reproduce the signature’s extra interactions.

If your decision is specifically between budget four-star options, the Hyacine four-star Light Cone comparison goes into that narrower choice. Here, the important question is which cone lets your complete build meet its healing, SPD and uptime goals.

6. 🔄 Hyacine Rotation, Energy and Skill Points

6.1 🌧️ Build Around the After Rain Window

Ultimate summons Ica if needed, heals the party and activates After Rain. During that state, allies gain Max HP and Ica attacks after Hyacine’s abilities. The state’s duration decreases at the start of Hyacine’s turns, so faster actions also increase the importance of refreshing it.

1. Before combat: use Technique when its opening heal/HP support helps the encounter.
2. Opening: establish Ica with Skill when you need healing or its presence; do not spend an extra setup Skill when the situation does not require it.
3. Ultimate ready: activate it before the Hyacine action you want to trigger Ica’s attack. On her own turn, using it before Basic or Skill can improve the window.
4. During After Rain: use Skill for healing, cleanse and stronger Energy generation; use Basic when the team needs SP and the resulting rotation remains safe.
5. Before the next damage window: check Ultimate progress, party HP and SP together.

6.2 🔋 Why ERR Does Not Guarantee One Universal Rotation

Hyacine’s Ultimate costs 140 Energy. Skill generates more Energy than Basic, and Ica contributes additional Energy through its mechanics. First-summon Energy is an opening benefit, not an extra refill on every Skill while Ica is already present.

An ERR Rope is the default because losing After Rain affects HP support, Ica attacks and healing together. Even so, Energy from incoming hits and teammates changes the cycle. I would not promise permanent uptime from a fixed three-action script without checking that specific team.

Likewise, she is not automatically SP-positive in every lineup. Frequent Skills can improve her output while consuming the party’s SP budget. If a carry misses its important Skill because Hyacine took the last point, revise the rotation or supports before adding another SPD target.

7. 👥 Best Hyacine Teams and When to Use Them

Choose a team that uses her healing, Max HP support or frequent Ica actions. The following are roster templates, not a measured damage ranking; stage mechanics and investment can change which performs best.

Team	Four-character lineup	Why consider it
Established Castorice core	Castorice / Evernight / Cyrene / Hyacine	HP movement, healing and complementary memosprite support.
Summeretto variant	Castorice / Evernight / Robin • Summeretto / Hyacine	A newer Remembrance support route; compare the action/resource plan with your owned Cyrene version.
Lower-investment Castorice	Castorice / Remembrance Trailblazer / Pela / Hyacine	Two limited units already owned, with accessible/roster-dependent supports.
Evernight-focused	Evernight / Cyrene / Remembrance Trailblazer / Hyacine	Healing for HP consumption and a core built around memosprite actions.
HP hybrid / frequent attacks	Mortenax Blade / Ashveil / Tribbie / Hyacine	HP support and repeated ally attacks; check the team’s SP requirements.

7.1 🐉 Why Castorice Is Such a Strong Partner

Castorice’s HP-consuming play pattern creates repeated healing demand. Hyacine restores that HP, adds an extra memosprite and supplies a Max HP window. The team can use much more of her kit than a lineup that only needs occasional emergency healing.

For missing-support replacements and full Castorice variants, the Castorice team guide covers the lineup question in detail. Choose the partners first, then tune Hyacine’s healing, Energy and SP use around their rotation.

7.2 🧠 Other Teams and Important Limits

Evernight and Cyrene can use the healing and action pattern in their own cores. HP-scaling carries such as Mydei and Blade are also natural candidates, provided the other supports fit the carry. Hyacine can sustain broader damage teams, but a healer that restores Energy or supplies a specific mechanic may solve a different roster problem better.

Robin • Summeretto is a distinct character from the original Harmony Robin. Replacing one with the other changes the rotation; do not copy an original-Robin action script without checking Summeretto’s kit. For Acheron-related debuff plans, the relevant enemy debuff comes from Hyacine’s signature, not her base healing kit.

8. 📈 Hyacine Trace Priority and Farming Plan

8.1 🔓 Upgrade the Healing Core First

Unlock all three major Bonus Abilities and the SPD minor Traces. For a healing-first build, my upgrade order is Ultimate → Memosprite Talent and Skill → Talent and Memosprite Skill → Basic ATK. If you later build around Ica damage, move the damage Talent/Memosprite Skill upward after sustain is secure.

Priority	Upgrade	What it fixes
1	Level/ascension gates, major Bonus Abilities, SPD nodes	Access to core mechanics and the full +14 Trace SPD.
2	Ultimate	After Rain’s HP-support window and active healing.
3	Memosprite Talent + Skill	Reactive and active healing reliability.
4	Talent + Memosprite Skill	Ica’s damage scaling.
5	Basic ATK	Low priority for the default sustain build.

8.2 🗺️ A Practical Farming Checklist

• ☐ Raise Hyacine and her chosen Light Cone to the levels your account can support; finish Level 80 when completing all SPD nodes.
• ☐ Farm A Glass of the Besotted Era for character ascensions; the full ascension requirement is 65.
• ☐ Obtain Bīja of Consciousness / Seedling of Manas / Flower of Ālaya for her Remembrance upgrades, plus required weekly materials shown in the live Trace menu.
• ☐ Complete the healing upgrades before repeatedly chasing marginal Cavern substats.
• ☐ Farm Warrior Goddess at Path of Thundersurge when unlocked; equip useful 2-piece SPD combinations in the meantime.
• ☐ Find an HP% Sphere and ERR Rope, then refine SPD while preserving the build’s healing and Energy plan.

From a planning perspective, I would spend the next batch of Power on the upgrade that removes the current bottleneck. Use the Trailblaze Power spending guide to balance fixed upgrades with relic farming, rather than spending every day in the same Cavern.

9. 🆓 Hyacine F2P Build: Where to Start and Stop

A F2P Hyacine build means equipment and upgrade choices for a player who already owns the limited character. It does not make Hyacine herself a guaranteed free unit.

Stage	Equipment / investment	Reasonable stopping point
Usable today	Owned Remembrance cone, correct main stats, strong SPD mixed pieces.	The team survives and core skills are unlocked.
Solid intermediate build	Memory’s Curtain Never Falls, a usable ERR Rope and Giant Tree.	Reach its 180-SPD healing tier when possible; improve the remaining SPD gradually.
Completed default target	Memory S5, strong Warrior Goddess pieces, reliable more-than-200 in-combat SPD.	Keep the functioning team; additional relic gains are optional.

If you own only part of a premium lineup, the Remembrance team comparison helps identify accessible replacements and shows which lower-investment teams still require limited characters.

10. ❌ Common Hyacine Build Mistakes

Mistake	Why it causes problems	Fix
Farming CRIT Rate	Gloomy Grin already adds 100%.	Prioritize SPD, HP% and useful CRIT DMG.
Treating exactly 200 as confirmed activation	The Trace requires SPD to exceed 200; the UI can hide decimals.	Check combat stats/effects and leave a margin.
Replacing ERR with HP% without a rotation check	Larger individual heals can come with less After Rain uptime.	Keep ERR by default.
Assuming every Skill is free in the SP budget	Hyacine competes with other Skill users.	Plan Basic/Skill decisions with the carry’s important turns.
Copying signature interactions onto a F2P cone	HP drain and the enemy vulnerability are cone-specific.	Separate base kit, cone effects and Eidolon effects.
Replacing the build for four weak matching pieces	Set completion can lose the SPD or healing that made the team work.	Compare complete equipment configurations.

When two relic combinations look close, compare their total SPD, HP and rotation conditions in a relic optimizer. Set the actual Light Cone and combat buffs first; a score based on the wrong assumptions can recommend the wrong piece.

12. 🎟️ Should You Pull Hyacine, Her Signature or Save?

From a planning perspective, Hyacine has the clearest pull case when an HP-based team needs better recovery and can use her support. Once the E0 team functions, S1 and Eidolons become investment choices rather than entry requirements.

Your situation	Pull or save?	Decision rule
Own Castorice/Evernight; healing is the main bottleneck	Consider Hyacine when officially available.	She covers recovery and complementary HP/memosprite functions.
Already own E0 Hyacine with a functional Memory S5 build	Saving is reasonable.	Complete missing roster roles before optional upgrades.
Committed to an HP team and want more offensive utility	Compare S1 with other team upgrades.	Signature adds SPD, HP-loss triggers and enemy vulnerability.
Choosing E1 versus S1	Compare the specific roster.	E1 expands After Rain’s HP/healing support; S1 adds different interactions. There is no universal winner.
Need a second carry or a different sustain function	Prioritize the larger account gap.	A luxury upgrade to one team may leave another unusable.
Only want E2+ for a showcase SPD/damage number	Save unless deliberately investing heavily.	The default guide does not require high Eidolons.
No official announcement for the banner you are planning around	Wait for verification.	Do not budget against a rumored countdown.

Before committing, check your pity and guarantee and compare that budget with the missing slot. A strong character can still be the wrong next purchase for a particular account.

13. ❓ Hyacine Build HSR FAQ

13.1 💬 What is the best Hyacine build in HSR?

The default is Warrior Goddess of Sun and Thunder with Giant Tree of Rapt Brooding, Outgoing Healing body, SPD boots, HP% Sphere and ERR Rope. Work toward more than 200 SPD in combat. Use her signature for dedicated investment or Memory’s Curtain Never Falls S5 for F2P value.

13.2 💬 Does Hyacine need exactly 200 SPD?

Her Tempestuous Halt condition says SPD must exceed 200. Exactly 200 is insufficient, and the integer display can hide decimals. Aim for a practical margin such as 201+ displayed, then check the live condition. She can still heal effectively while you develop a lower-SPD build.

13.3 💬 Does Hyacine need CRIT Rate or CRIT DMG?

Gloomy Grin adds 100% CRIT Rate to her and Little Ica, so CRIT Rate rolls are generally wasted after unlocking it. CRIT DMG remains useful for Ica, but SPD, HP-based healing and Ultimate uptime come first in the default sustain setup.

13.4 💬 Should Hyacine use an HP or healing body?

Outgoing Healing is the default because it improves recovery and the healing resource behind Ica’s damage. An HP% body is a usable temporary piece when its substats solve a real problem. Compare the whole build before discarding a strong interim body.

13.5 💬 Can Hyacine use an HP% Rope instead of ERR?

Yes, as a specialized choice when the actual team supplies enough Energy to maintain the desired After Rain windows. ERR is the safer default. A larger single heal does not automatically compensate for losing the HP-support window and Ica’s additional attacks.

13.6 💬 Is Hyacine’s signature Light Cone necessary?

No. E0 Hyacine retains healing, cleanse, HP support and Ica with a non-signature cone. The signature adds SPD and separate HP-drain/debuff interactions. Pull for those benefits when they suit the account, rather than treating S1 as a requirement to use her.

13.7 💬 Does Little Ica inherit Hyacine’s Speed for normal turns?

Little Ica stays at 0 SPD and does not occupy the normal Action Order. Its attacks during After Rain follow Hyacine’s abilities. Increase Hyacine’s SPD and manage the state’s uptime instead of applying an ordinary owner-and-summon turn-tuning rule.

13.8 💬 Is Hyacine only good with Castorice?

No. Castorice makes especially clear use of the healing and HP support, but Evernight, Cyrene cores, other HP-scaling carries and some frequent-attack teams can also benefit. Team value depends on the carry’s resource needs, support package and Skill Point budget.

13.9 💬 When is Hyacine’s next rerun?

Use the newest official Event Warp announcement or in-game Warp screen for that answer. The historical windows above are not a future schedule. This guide does not assign a next-rerun date from old banner intervals or unconfirmed reports.
