Hyacine Build Guide HSR – Best Relics, Light Cones, Teams & Eidolons

by Mark Smith · February 16, 2026

Hyacine is a 5-star Wind Remembrance healer who summons a memosprite called Little Ica to provide reactive healing every time an ally takes damage.
She scales on Max HP for both healing output and damage. Speed is equally critical — hitting 200+ SPD in combat is her key breakpoint.
At 200+ SPD, her A6 trace boosts her and Little Ica’s Max HP by 20% and increases Outgoing Healing by 1% for every excess SPD point above 200, up to 200 excess.
Her Ultimate applies the After Rain state — boosting all allies’ Max HP by 30% for 3 turns, directly amplifying HP-scaling DPS like Castorice, Blade, and Mydei.
Her A6 trace also gives the whole team 20% All-Type RES PEN while Little Ica is on the field — always active in normal gameplay.
Best Light Cone: Long May Rainbows Adorn the Sky (her signature) — provides 18% SPD, HP drain on every action, and an 18% Vulnerability debuff.
Best Relics: Warrior Goddess of Sun and Thunder (4-piece) + Giant Tree of Rapt Brooding (Planar Ornament).
Best teams: Castorice / Evernight / Cyrene / Hyacine (Remembrance), Blade / Sunday / Tribbie / Hyacine (HP drain).
E1 is the top investment target — boosts all allies’ Max HP by 50% during After Rain and adds on-hit reactive healing.
Hyacine debuted in Version 3.3 (May 2025) and last ran in Version 4.1 (March–April 2026). Watch for future reruns.

Who Is Hyacine in Honkai Star Rail?

Hyacine is a 5-star Wind character following the Path of Remembrance in Honkai Star Rail. Her full name is Hyacinthia. She is a Chrysos Heir who guards the Sky Coreflame, a physician from the cloud city-state of the Twilight Courtyard. She debuted in Version 3.3 (May 2025) and has consistently been rated T0 in Memory of Chaos, Pure Fiction, and Apocalyptic Shadow as of patch 4.3. She is widely considered the best sustain character in the current game.

In the game’s lore, Hyacine is tasked with inheriting her ancestors’ will and mending the torn fabric of dusk and dawn. Her healing is described as rainbow light pouring down to dissolve all grudges and bring dawn back to the land. In practice, this translates into an extremely fast, proactive healer who acts more frequently than most characters in the game and keeps allies alive through constant reactive healing even when she is not taking her own turn.

What makes Hyacine unique among healers is her combination of roles. She is the definitive best sustain for Castorice due to her HP drain mechanics generating Newbud. She is also excellent for HP-scaling DPS like Blade and Mydei. And she brings utility that most healers simply cannot offer: team-wide Max HP buffs, 20% All-Type RES PEN for the full party, and off-turn AoE damage through Little Ica’s Memosprite Skill.

Hyacine last ran in Version 4.1 (March 24 – April 8, 2026). Watch for her next rerun announcement. For official patch details, check the HoYoverse official Honkai Star Rail news page.

Hyacine Kit Overview – How Her Abilities Work

Hyacine’s kit is built around three healing systems working simultaneously: her Skill heals the whole team, her Ultimate applies a Max HP buff and batch heals, and Little Ica provides reactive off-turn healing after every instance of ally HP reduction. The healing tally accumulated from all three sources powers Little Ica’s AoE damage attack. Understanding all three is essential for getting full value from her build.

Basic Attack – Fair Weather Ahead

Deals Wind DMG equal to 50% of Hyacine’s Max HP to one enemy. Used primarily to generate Energy when Skill Points are tight. Because all her abilities scale with Max HP rather than ATK, this Basic Attack also contributes to the Healing Tally at no cost. Use it when you cannot afford a Skill and need to keep the Energy cycle moving toward the next Ultimate.

Skill – Love Over the Rainbow

Summons Little Ica to the field (or re-summons it if it disappeared) and immediately restores HP equal to 8% of Hyacine’s Max HP plus 160 for all allies. This is Hyacine’s primary active healing tool and her SP-spending action. Every heal from this Skill adds to the Healing Tally. If Little Ica is already on the field, this instead provides a smaller direct heal to all allies and refreshes Little Ica’s survival. Always try to use Skill when the team needs healing or when you want to build the Healing Tally faster for Little Ica’s damage window.

Ultimate – We Who Fly Into Twilight

This is Hyacine’s most impactful ability. It:

Summons Little Ica (or restores its HP if already present).
Heals all allies for HP equal to 10% of Hyacine’s Max HP plus 200, and heals Little Ica for 12% plus 240.
Places Hyacine in the After Rain state for 3 turns (decreasing by 1 each time Hyacine’s turn begins).
While After Rain is active, all allies’ Max HP increases by 30% plus 600.

The 30% Max HP buff to the entire team is a critical multiplier for HP-scaling DPS characters. Castorice’s Newbud threshold is based on HP lost, so more Max HP means bigger HP drains and faster Newbud racking. Blade and Mydei both scale damage directly with Max HP. Even non-HP-scaling characters benefit from the survivability boost. Keeping After Rain active as much as possible through frequent Ultimate use is Hyacine’s primary rotation goal. Her high base SPD combined with the 200+ SPD build means she naturally reaches her Ultimate more often than slower healers.

Talent – First Light Heals the World

Little Ica starts with Max HP equal to 50% of Hyacine’s Max HP. Every time Hyacine or Little Ica provides healing, Little Ica gains a stack of 80% increased DMG dealt (up to 3 stacks, lasting 2 turns). This means the more Hyacine heals, the more damage Little Ica deals. In active fights with constant HP drain and healing, Little Ica can maintain near-permanent maximum stacks for significant additional damage output. At 3 stacks, Little Ica’s Memosprite Skill deals enormous AoE Wind DMG based on the accumulated Healing Tally.

Little Ica’s Memosprite Talent – Take Sky in Hand

This is Hyacine’s most unique and practically impactful passive. Little Ica has 0 SPD and does not appear on the action order — it acts completely off-turn, outside of any character’s normal move. Whenever any ally (except Little Ica) has their HP reduced, Little Ica triggers automatically: it consumes 4% of its own Max HP and restores HP equal to 2% of Hyacine’s Max HP plus 20 for the ally that lost HP. This trigger fires at the start of any target’s turn or after any target takes action. In practice, this means Little Ica heals someone after almost every hit lands in the entire fight — not just on Hyacine’s turn. It is the most proactive and responsive healing mechanic in the game, making ally deaths extremely rare while Hyacine is properly built.

Little Ica’s Memosprite Skill – Rainclouds, Time to Go!

When Little Ica activates this attack, it deals AoE Wind DMG to all enemies equal to 20% of the total Healing Tally accumulated by Hyacine and Little Ica across the entire battle, then clears 50% of that tally. The Healing Tally is the sum of every single HP point healed by any source connected to Hyacine throughout the fight. In extended endgame fights with constant HP drain and healing cycles, this tally builds to enormous values — and Little Ica’s Memosprite Skill converts it into massive AoE damage. This is Hyacine’s primary personal DPS window.

A2 Trace – Gentle Rain, Serene Heart

At the start of the next battle after a fight ends, Hyacine restores HP equal to 30% of her Max HP plus 600 for all allies and increases their Max HP by 20% for 2 turns. This ensures the team enters every new fight in endgame content at full HP with a pre-loaded Max HP buff — extremely valuable in Memory of Chaos where multiple waves and rooms need to be cleared consecutively.

A6 Trace – Tempestuous Halt

This is Hyacine’s most important trace and the reason the 200 SPD breakpoint matters so much. When Hyacine’s SPD exceeds 200, two things happen:

Hyacine and Little Ica gain a 20% Max HP increase — boosting all of Hyacine’s healing and damage multipliers simultaneously.
For every 1 SPD above 200, Hyacine and Little Ica’s Outgoing Healing increases by 1%, up to a maximum of 200 excess SPD (200% bonus healing).

In practice, hitting 220 SPD in combat gives 20% bonus healing. Hitting 250 SPD gives 50% bonus healing on top of the Max HP boost. Every point of SPD above 200 is meaningfully converting into raw healing power. This is why SPD is Hyacine’s top stat — not just for action frequency, but for healing output.

A4 Trace – O Sky, Heed My Plea

While Little Ica is on the field, all ally targets gain 20% All-Type RES PEN. Since Little Ica is on the field for essentially the entire fight in normal gameplay, this is a permanent passive team-wide amplifier. It applies to every damage type simultaneously — a free multiplicative multiplier for Castorice, Evernight, Cyrene, Blade, and any other ally. This trace alone makes Hyacine worth including in virtually any competitive team.

Hyacine Best Light Cones in HSR

Hyacine follows the Path of Remembrance. Only Remembrance path Light Cones activate passive effects on her. Her signature is best-in-slot by a meaningful margin and is recommended as the first investment after pulling her.

Long May Rainbows Adorn the Sky (Signature – Best in Slot)

Hyacine’s 5-star signature Light Cone is transformative for her kit. At S1, it provides 18% SPD — the single most important stat on Hyacine for reaching the 200 SPD breakpoint. Without it, reaching 200 SPD requires heavy substat investment in SPD rolls. With it, the breakpoint becomes reachable with moderate investment. The signature also causes every Hyacine action to drain a small amount of HP from all allies, which enables Castorice’s Newbud generation and Blade’s follow-up attack trigger passively, without needing enemies to deal damage. Finally, when Little Ica uses its Memosprite Skill, it applies an 18% Vulnerability debuff to all enemies — a damage-taken increase that benefits the entire team’s output. This Light Cone does not just make Hyacine better as a healer; it unlocks entirely new team archetypes that E0S0 Hyacine cannot access.

Memory’s Curtain (Herta Store – Best F2P Option)

The best free-to-play Light Cone for Hyacine, obtainable from the Herta Store with Undying Starlight. It provides significant SPD%, which is the key stat for reaching the 200 SPD breakpoint. It also offers a team-wide DMG buff. This is the recommended option for players who cannot pull Hyacine’s signature, and it is genuinely competitive at S5. Prioritize getting this to S5 before investing in other options.

Multiplication (4-Star Herta Store)

A serviceable alternative that provides Max HP and Outgoing Healing. Max HP directly scales Hyacine’s healing output and Little Ica’s Max HP, which in turn boosts the Healing Tally. However, this Light Cone does not provide SPD, making reaching the 200 SPD breakpoint significantly harder. Use it only if Memory’s Curtain is unavailable.

Post-Op Conversation (4-Star)

Energy Regeneration Rate and Outgoing Healing — a classic healer Light Cone. Helps with Ultimate cycle frequency and healing output but offers no SPD at all. The Energy Regen helps Hyacine use her Ultimate more often, indirectly increasing After Rain uptime. Viable as a temporary placeholder, but should be replaced with Memory’s Curtain when available.

Hyacine Best Relics in HSR

Hyacine’s relic priority is dominated by one goal: reach 200 SPD in combat. Every other stat is secondary to this threshold. Her A6 trace turns excess SPD into healing power and Max HP, so after hitting 200, every additional SPD point still contributes directly to her output. The relic set and Planar Ornaments are chosen specifically because they provide SPD while also improving her healing and support functions.

Best 4-Piece Relic Set: Warrior Goddess of Sun and Thunder

This is Hyacine’s dedicated relic set and the clear best choice. The 2-piece bonus gives a direct SPD increase, helping hit the critical 200 SPD threshold without over-relying on substats. The 4-piece is the key: when Hyacine or Little Ica heals an ally, they both enter the Gentle Rain state (lasting 2 turns), which provides an additional 6% SPD to Hyacine and a 15% CRIT DMG buff to the entire party. Since Hyacine heals constantly through Little Ica’s off-turn reactive healing, Gentle Rain stays up for essentially the entire fight. The team-wide CRIT DMG is a meaningful damage multiplier that benefits every DPS character on the team, not just HP-scalers. Farm this set exclusively for Hyacine.

Alternative: 2-Piece Warrior Goddess + 2-Piece Messenger Traversing Hackerspace

A viable temporary setup while farming for a complete 4-piece Warrior Goddess set. Both 2-piece sets provide SPD bonuses, making the combined setup excellent for reaching the 200 SPD breakpoint with fewer relic pieces needed from any single domain. Use this if your best Warrior Goddess pieces have poor substats compared to your Messenger pieces.

Best Planar Ornament: Giant Tree of Rapt Brooding

Hyacine’s best Planar Ornament. It provides SPD%, which contributes directly to reaching and exceeding the 200 SPD breakpoint, and a Max HP% bonus when SPD is above a threshold. Both stats feed directly into her A6 trace’s healing and damage multipliers. This is the ornament set to farm in Simulated Universe specifically for Hyacine.

Alternative Planar Ornament: Sprightly Vonwacq

Provides Energy Regeneration Rate and SPD. Useful if you need both the ERR for more frequent Ultimates and the SPD contribution toward 200. A strong choice if your Skill Point economy is tight and you need After Rain uptime to be more consistent. Use Giant Tree as your primary target but run Sprightly Vonwacq if you have better substats there.

Relic Main Stats to Target

Head: HP (fixed)
Hands: ATK (fixed — does not help Hyacine but the slot cannot be changed)
Body: Outgoing Healing Boost — increases all of her healing output directly.
Feet: SPD — mandatory. Every SPD point gets Hyacine closer to 200 in combat.
Planar Sphere: HP% — boosts Little Ica’s Max HP and all healing multipliers.
Link Rope: Energy Regeneration Rate — helps maintain consistent Ultimate cycles for After Rain uptime. Can switch to HP% if running the signature LC, which helps handle the SPD requirement.

Key Substat Priority

SPD is the absolute top priority for substats — stack as many SPD rolls as possible until you exceed 200 in combat. After SPD, HP% contributes to healing and Little Ica’s Max HP. CRIT DMG has value for Little Ica’s Memosprite Skill damage and becomes the best offensive substat after E4. Effect RES is useful at 32%+ to avoid Hyacine getting CC’d, which would disable her reactive healing. Avoid ATK% and flat ATK entirely.

Stat Targets

SPD: 200+ in combat (Hyacine’s base SPD is 110; she gains 14 from Minor Traces, making 124 base. Signature LC gives 18% → ~24 SPD. Warrior Goddess 2-piece gives more. Substat SPD rolls cover the rest. Target 176+ base SPD to safely hit 200+ with all buffs active.)
HP: 5,000+ (higher is better; Little Ica’s Max HP scales at 50% of Hyacine’s Max HP)
CRIT DMG: 100%+ (valuable for Little Ica’s Memosprite Skill output; more meaningful at E4)
Effect RES: 32%+ (prevents Crowd Control from disrupting her reactive healing)

Hyacine Best Teams in HSR 4.3

Hyacine is a universal sustain who works in almost any team. She is, however, at her absolute best in teams with HP-drain mechanics, because her signature’s active HP drain converts into Castorice’s Newbud and Blade’s follow-up triggers. In teams without HP synergy, she still provides strong healing, Max HP buffs, and the 20% All-Type RES PEN — but those bonus synergies are lost.

One rule applies: Hyacine heals through direct HP restoration. She is the correct healer for teams that need HP to actually drop. Do not pair her with shielders on the same team — shields intercept the HP loss before Little Ica’s reactive healing triggers, partly defeating the purpose of her kit in HP-drain compositions.

Best Remembrance Team: Castorice / Evernight / Cyrene / Hyacine

This is both the best team for Hyacine and the best team in the current Remembrance meta. Castorice consumes ally HP to build Newbud. Hyacine’s reactive healing through Little Ica tops that HP back up — and the healing itself feeds Castorice’s A2 trace, converting heals into additional Newbud. Every point of HP drained and then healed contributes to both characters’ mechanics simultaneously. Evernight provides CRIT DMG buffs to all Memosprites and team-wide 20% RES PEN. Cyrene provides True DMG amplification and unique team buffs. The community investment recommendation for this team is E0S1–E2S1 Castorice / E1S1 Evernight / E1S1 Hyacine / E0S1 Cyrene.

HP Drain Synergy Team: Blade / Sunday / Tribbie / Hyacine

Blade is a Destruction DPS who needs HP to drop to trigger his follow-up attacks and stack his Talent. Hyacine’s signature Light Cone drains HP from allies on every action, triggering Blade’s talent stacks passively throughout the fight — making his rotations far smoother and faster. Sunday provides 100% Action Advance, CRIT DMG buffs, and energy restoration. Tribbie provides RES PEN and a 30% DMG Taken debuff. This team showcases Hyacine’s signature LC unlocking an entirely new Blade archetype.

Accessible Remembrance Team: Castorice / Trailblazer (Remembrance) / Tribbie / Hyacine

A strong and accessible Remembrance team that does not require Evernight or Cyrene. Trailblazer (Remembrance) provides CRIT DMG, True DMG buffs, and Mem’s Memosprite actions feed Castorice’s Newbud through Evernight’s A2-equivalent mechanic. Tribbie adds RES PEN and damage amplification. Hyacine handles sustain and Max HP buffs. This team clears all endgame content reliably.

Universal Hypercarry Sustain: Phainon / Sunday / Bronya / Hyacine

Hyacine as the sustain slot in a hypercarry team with Phainon. Phainon’s Khaslana transformation protects all allies (they depart the field entirely), so Hyacine’s healing is less critical during the 8-turn window. However, her Max HP buff from After Rain is snapshotted into the transformation, and her 20% RES PEN passive benefits the team before transformation. She provides solid survivability without costing offensive output. Sunday and Bronya handle the Action Advance and CRIT buff slots.

Mydei HP-Scaling Team: Mydei / Sunday / Tribbie / Hyacine

Mydei is an HP-scaling Destruction DPS who actively loses HP as part of his kit. Hyacine’s After Rain Max HP buff (30%) directly amplifies Mydei’s damage multipliers. Little Ica heals Mydei after every HP drop, which is constant given his kit. The synergy is natural and strong. Sunday handles Action Advance and Energy. Tribbie provides RES PEN and DMG amplification.

Notable Partners

Acheron – Hyacine’s signature applies HP drain, which does not generate Nihility stacks but does help certain Acheron team formats. Hyacine provides reliable healing for Acheron’s aggressive speed builds.
Aglaea – Hyacine heals all allies including Garmentmaker (the memosprite), and her Max HP buff boosts Aglaea’s performance. The healing feeds into Aglaea’s energy cycle through indirect support.
Luocha / Gallagher – When Hyacine is unavailable, these are the fallback healers. Neither provides the Remembrance Memosprite synergy or the 20% RES PEN passive, but both offer reliable direct healing.

Hyacine Trace Priority

Invest your upgrade materials in this order:

Major Traces A4 and A6 – Unlock immediately. A4 (20% All-Type RES PEN for the whole team while Little Ica is on the field) is always active and requires no management. A6 (Tempestuous Halt — the 200 SPD breakpoint effect) is the core of her entire build philosophy. Both must be unlocked before anything else. Every material spent here translates into permanent, passive team-wide value.
Skill – Second. Her Skill is the primary active healing tool and the main source of Healing Tally build-up for Little Ica’s Memosprite Skill. Higher Skill level increases HP restoration per use.
Ultimate – Third. Higher Ultimate level increases the HP restoration from the batch heal and the Max HP boost percentage from After Rain. Both directly amplify the team’s survivability and HP-scaling DPS output.
Talent – Fourth. The Talent governs Little Ica’s DMG increase per healing stack. Higher Talent level increases the 80% DMG bonus per stack. Meaningful for Little Ica’s Memosprite Skill output but lower priority than the core healing abilities.
Basic Attack – Last. Used for Energy generation. Contributes minimally to the Healing Tally. Level this only after everything else is maxed.

Hyacine Eidolons – Which Ones Are Worth It?

Hyacine performs well at E0, but her E1 is one of the highest-value Eidolons for HP-scaling team compositions. E2 is a strong team-wide SPD buff that is near-permanent in HP-drain teams.

E1 – Best Value Eidolon (Recommended First Investment)

E1 modifies the After Rain state significantly. When Hyacine is in After Rain, the Max HP boost for all allies jumps from 30% to 80% — a massive amplifier for HP-scaling DPS like Castorice, Blade, and Mydei. At E1, those characters are fighting with nearly double their base Max HP factored into their damage calculations during After Rain windows. E1 also adds reactive on-hit healing: whenever Hyacine’s allies attack, they receive a small HP restoration equal to 8% of Hyacine’s Max HP. This is similar to Luocha’s passive healing style and effectively makes the team nearly unkillable in most endgame scenarios. For HP-scaling team owners, E1 is the primary investment target after the signature Light Cone. Community guides rate E1S1 as the recommended stopping point for most dedicated Hyacine players.

E2 – Excellent Team SPD Buff

Whenever any ally loses HP, all allies gain a 30% SPD increase for 2 turns. In HP-drain teams (Castorice, Blade, Mydei), HP drops happen every few seconds — making this effectively a near-permanent 30% SPD buff for the entire team. This dramatically increases healing output (more SPD means more A6 excess above 200) and team DPS through faster action cycling. For HP-drain-focused teams, E2 is considered an incredible upgrade. Community sources describe the resulting teams as nearly immortal in most endgame content.

E4 – Personal DPS Enhancement

E4 adds 2% CRIT DMG for Hyacine and Little Ica for every 1 SPD above 200. Since Hyacine regularly exceeds 220–240+ SPD in combat, E4 translates into 40–80%+ CRIT DMG for Little Ica — dramatically boosting its Memosprite Skill damage. This makes Hyacine a meaningful sub-DPS contributor at E4, not just a healer. Valuable for invested players but not a priority over E1 and E2.

E6 – Maximum Investment

E6 boosts the Healing Tally’s damage conversion and provides additional team-wide buffs. A strong spike at very high investment, but the practical ceiling for most players is E1 or E2.

Hyacine Rotation Guide – How to Play Her

Hyacine’s rotation is straightforward because Little Ica handles most of the moment-to-moment healing automatically. Your primary job is to maintain After Rain uptime and keep the Healing Tally building.

Battle Start

Hyacine’s A2 trace pre-loads the team with HP and a 20% Max HP buff entering the first wave. Little Ica auto-summons at battle start from the Talent. Use Skill on the first turn to immediately apply healing and start building the Healing Tally. The 200+ SPD build means Hyacine often acts before any enemy in the first cycle, giving the team a healed buffer before taking damage.

Core Loop – After Rain Maintenance

Use Ultimate as soon as it is available to apply After Rain and batch-heal the team. After Rain lasts 3 turns on Hyacine’s turn decrements, so with high SPD and proper Energy Regen, you should be able to refresh After Rain before it fully expires in most fights. When Ultimate is not ready, use Skill to heal and build the Healing Tally. Use Basic ATK when Skill Points need to be conserved for SP-hungry teammates.

Little Ica’s Passive Healing

You do not need to actively manage Little Ica’s reactive healing from the Memosprite Talent — it triggers automatically after every instance of ally HP reduction in the entire fight. What you do control is the Healing Tally that powers Little Ica’s Memosprite Skill. Every heal from Skill, Ultimate, and Little Ica’s reactive heals adds to this tally. When the tally is large enough, Little Ica fires its Memosprite Skill on its own schedule, dealing AoE Wind DMG and clearing 50% of the tally. In long fights, this tally resets and rebuilds multiple times, creating recurring damage windows from a character ostensibly built as a healer.

Speed Management

With 200+ SPD, Hyacine acts roughly twice for every one action of a 100 SPD enemy. In practice, this means she takes 2 turns per MoC cycle in most content, often more. With the signature LC’s 18% SPD boost and Warrior Goddess’s SPD bonuses, hitting 220–240 SPD in combat is realistic with proper substat investment. At 240 SPD, the A6 trace is giving her 40% bonus healing and 20% bonus Max HP on top of base stats — a meaningful jump from E0S0 Hyacine.

Should You Pull Hyacine in HSR 4.3?

Yes — Hyacine is the best sustain character in the current game by a significant margin. If you own or plan to pull Castorice, she is a must-pull. The synergy between Castorice’s HP drain and Hyacine’s reactive healing is the strongest healer-DPS pairing in the Remembrance archetype, and no other sustain matches what she provides in that team.

Even outside of Castorice teams, Hyacine brings a unique combination of benefits that no other healer provides simultaneously: reactive off-turn healing through Little Ica, a 30% Max HP buff for the entire team, 20% All-Type RES PEN as a permanent passive, meaningful off-turn AoE damage through the Healing Tally, and strong SP-positive gameplay at E1 that does not burden teammates. She is T0 in all three endgame modes, and her value has consistently grown as HP-scaling characters become more prominent in the meta.

The main consideration is the signature Light Cone. Without it, reaching 200 SPD in combat requires heavy SPD substat investment. With it, the 18% SPD bonus makes the breakpoint accessible with moderate relic farming. If you can pull both Hyacine and her signature, the combination is extremely strong. If you can only pull one, go for Hyacine first — she works without the signature, just with more SPD substat pressure.

For teams to pair with Hyacine, check our guides for Castorice, Evernight, Cyrene, Blade, Mydei, and Phainon. For alternative sustain options if Hyacine is unavailable, see our guides for Luocha and Gallagher.
