Hyacine HSR – Guide, Skills, Builds, Teams & More

Hyacine: Guide, Skills, Builds, Teams & More

Hyacine is a Wind Remembrance character disguised as an Abundance healer. Don’t underestimate Hyacine’s damage just because she’s a healer! Her memosprite, Little Ica, deals considerable damage as a sub DPS. Hyacine’s healing numbers aren’t the biggest, but the HP increase for the whole team will keep her party safe no problem.

Hyacine with her Lightcone arguably becomes the best support for all teams minus break, but she is best suited for HP scaling DPS. Hyacine can be flexed into almost all comps, and performs well in all endgame modes.

HSR Hyacine Release Date

Hyacine’s banner will be in the first half of Version 2.5 releasing on May 21st, 2025 and will run until June 11th, 2025.

Hyacine HSR Kit Overview (Trace Level 10)

Hyacine is a healing sustain that also comes with a mini nuke in the form of her memosprite, Little Ica. Little Ica’s damage is no joke.

Skill and Ultimate:

Hyacine’s Skill summons Little Ica, restores HP 8% of her Max HP plus 160 to allies, and 10% of her Max HP plus 200 to Little Ica. It is a full AoE heal, unlike say Huohuo who can only heal 3, and can even heal memosprites like Mem.

Her Ultimate can also summon Little Ica, restores 10% of her max HP plus to all her allies and a bit more to Little Ica (12% plus 240), as well as putting her in the “After Rain” state for 3 turns. The state’s duration decreases whenever Hyacine takes a turn. In this state, allies have their HP increased by 30% plus 600.

This increase in HP makes her one of the safest sustains in the game, as your team becomes quite bulky. It is also a great boost for HP DPS, as they scale off of it.

Memosprite Skills and Talent:

Little Ica does not appear on the Action Order, has zero SPD, and is immune to debuffs. Instead of waiting for its turn, Ica immediately gets a turn and takes an action whenever Hyacine uses an ability while she’s in the “After Rain” state, which she obtains from her Ultimate.

When ally targets are damaged, Little Ica consumes 4% of its own HP and restores them by 2% of Hyacine’s Max HP plus 20 to the ally target when the team takes a turn. While in the “After Rain” state, Little Ica heals all allies additionally by the same amount mentioned above.

When Little Ica takes action, it does an AoE attack, based off of 20% of the tally of healing done by Hyacine and Little Ica, and clears it by 50% after its attack. This is to prevent an infinite damage ceiling by just continuously healing. Since Little Ica’s damage is based on how much you heal, you want to Skill as often on Hyacine’s turn.

When summoned, Little Ica gives Hyacine 15 Energy, and an extra 30 when it’s first summoned. This conveniently allows Hyacine to get up her Ultimate on her first turn after Skilling.

In the event Little Ica dies, it will advance Hyacine by 30%. This is unlikely to happen as Little Ica is quite tanky, unless you are playing high difficulties of SU/DU.

Talent:

When Hyacine summons Little Ica, its max HP will be 50% of Hyacine’s Max HP. Whenever Hyacine or Little Ica heals, Ica’s DMG increases by 80% for 2 turns, stacking up to 3 times.

This means that Little Ica gets a 240% DMG buff for just a bit of healing, letting it launch nukes as a healer.

Traces and Technique:

• A2: Hyacine and Little Ica have 100% CRIT Rate, and their healing increases for allies with less than 50% HP.
• A4: Hyacine gets 50% Effect Res and her Ultimate/SKill cleanses 1 debuff on all allies.
• A6: Hyacine’s HP increases by 20% if she’s faster than 200 SPD. For every excess speed, Hyacine and Little Ica’s Outgoing Healing increases by 1% per 1 SPD, up to 200 (total 400). Hitting this excess speed limit under normal conditions is not realistic.

Hyacine’s Technique increases allies’ max HP by 20% for 2 turns and restores 30% of her max HP plus 600 at the start of battle. This may seem not that helpful at first glance, but the healing upon entering battle was included in mind with her relic set “Warrior Goddess of Sun and Thunder”, letting her activate the SPD and CRIT DMG bonus immediately.

1. Cradle the Candle of Night: 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.
2. Come Sit In My Courtyard: When any ally target’s HP decreases, this unit’s SPD increases by 30% for 2 turn(s).

Eidolon Priority

Hyacine’s Eidolons are great overall, especially if you’re an HP DPS or looking to increase Little Ica’s damage. However her Eidolon values to teams is not universal, compared to say Harmony Eidolons.

Her E1 now increases allies’ Max HP by 80% when Hyacine uses her Ultimate, as well as providing on-hit healing like Luocha/Gallagher whenever her teammates attack. Your teams should be immortal, unless an enemy comes out that can hit for some obscene damage.

E2 is a permanent 30% increase in SPD for the whole team, as you’re bound to lose some HP. This also buffs Hyacine’s healing due to her A6 trace.

E4 gives Hyacine an extra 2% CRIT DMG for every excess 1 SPD based off of her A6 trace, giving a boost to Little Ica’s damage.

E6 is quite nuts, giving 20% All-Type RES-PEN when Little Ica is present, as well as lowering the cleared healing tally from 50% to 12%, which will give a massive boost to Ica’s damage.

• Eidolon 1: High
• Eidolon 2: High

HSR Hyacine Light Cones

Premium Options

Long May Rainbows Adorn the Sky: Increases the wearer’s SPD by 18% / 21% / 24% / 27% / 30%. When the wearer uses Basic ATK, Skill, or Ultimate, consumes all allies’ HP equal to 1% / 1.25% / 1.5% / 1.75% / 2% of their current HP and additionally deals 1 instance of Additional DMG of the wearer’s memosprite Type equal to 250% / 312.5% / 375% / 437.5% / 500% of the total consumed HP to the attacked target after the next attack launched by the wearer’s memosprite. The total HP consumed is then reset. When the wearer’s memosprite uses Memosprite Skill, increases the DMG taken by all enemies by 18% / 22.5% / 27% / 31.5% / 36% for 2 turn(s). The same types of effects cannot stack.

Hyacine’s Light Cone is fantastic for her for many reasons. The 18% SPD increase is great for Hyacine, since her healing increases with more SPD due to her A6, and more healing increases Ica’s damage.

The HP consumption is there to trigger Little Ica’s talent healing when allies lose HP. It is also convenient that her Signature does one extra damage on the next memosprite’s attack based off of total consumed HP, which only Hyacine’s kit offers. Lastly whenever a memosprite uses a Skill, it applies an 18% Vulnerability debuff, increasing her teammate options as well as providing amp to the team.

F2P Options

Memory’s Curtain Never Falls: Increases the wearer’s SPD by 6% / 7.5% / 9% / 10.5% / 12%. After the wearer uses Skill, increases the DMG dealt by all allies by 8% / 10% / 12% / 14% / 16%, lasting for 3 turn(s).

Hyacine is not completely restricted unlike Castorice, in that her F2P option is still a Remembrance Cone. The Herta Shop Light Cone gives her 12% speed which is great, and gives DMG increase to all allies whenever she Skills, which she should do as often to increase her healing tally.

A viable substitute to her Signature that won’t affect her sustaining ability much but loses out on utility and damage, which is understandable.

HSR Hyacine Main Stats

• Body: Outgoing Healing Boost > HP%
• Feet: Speed
• Orb: HP%
• Rope: Energy Regeneration Rate

Hyacine’s main stats are pretty linear, as she’s a healer/sub DPS. A Healing Body is preferred, as an increase in her healing is better to increase her tally. Speed boost is non-negotiable, as she wants at least 200 SPD to get more Healing from her A6. Lastly she wants an ER rope so that she can keep up her “After Rain” state up as much as possible.

HSR Hyacine Sub Stats

• SPD
• HP
• CRIT DMG
• Effect RES

Goals & Speedtuning:

Hitting at least 200 SPD with Hyacine is recommended, and not that as difficult as it sounds since she already gets 14 SPD from her traces. In addition, the BiS relic sets combined give 18% SPD, and either the Herta Cone or her Signature give 12% / 18% SPD. Combining all of this Hyacine with the F2P Herta Cone is already at 182 SPD in-battle, without any speed substats.

Hyacine and Little Ica already have 100% CR thanks to her A2, so only CRIT DMG and HP% is needed. Hyacine gets 50% Effect RES already from her A4, but more to prevent CC can never hurt.

HSR Hyacine Relics

Warrior Goddess of Sun and Thunder

• 2-Pc: Increases SPD by 6%.
• 4-Pc: When the wearer and their memosprite provide healing to ally targets aside from themselves, the wearer gains “Gentle Rain”, which can be triggered up to 1 time per turn, lasting for 2 turn(s). While the wearer has “Gentle Rain”, increases their SPD by 6% and all allies’ CRIT DMG by 15%. This effect cannot be stacked.

This relic was made with Hyacine in mind, as she’s the only memosprite that provides healing to allies (RMC only heals Mem).

In addition, Hyacine can trigger “Gentle Rain” immediately if she enters battle with her technique, giving her total 12% SPD to her and 15% CRIT DMG to all allies.

2Pc SPD/SPD

• 2-Pc: Increases SPD by 6%.

A temporary double 2pc Spd/Spd can be used until you get a 4pc Warrior set since it releases the same patch as Hyacine.

However, 12% SPD is already baked into Warrior if you can trigger “Gentle Rain”, which Hyacine easily can, so this relic should only be a placeholder till it can be replaced.

HSR Hyacine Planar Sets

Giant Tree of Rapt Brooding

• 2-Pc: Increases the wearer’s SPD by 6%. When the wearer’s SPD is 135/180 or higher, the wearer and their memosprite’s Outgoing Healing increases by 12%/20%.

Another planar that advertises directly “Use with Hyacine.” Hyacine achieves at minimum 182 SPD without substats with proper relics and lightcones, getting 20% increased healing for both her and Little Ica.

Any supportive planar: Hyacine is not a main DPS, so any supportive planar to assist her main DPS is fine as a placeholder till a Giant Tree pair is farmed, or if Hyacine’s healing and damage is not a priority.

HSR Hyacine Teammates

Hyacine at E0S1 is arguably the best sustain for most teams bar break, as she provides great sustain, debuff removal, vulnerability from her lightcone, and sub DPS levels of damage from Litlte Ica. These DPS are just a few that have more notable benefits from her kit.

Main DPS

Castorice: Hyacine is Castorice’s BiS healer by far, beating Gallagher even at E0S0. Hyacine’s fast speed lets her get multiple actions to heal, and she doesn’t depend on besotted debuff to get out healing. One of Gallagher’s downsides is that since his healing multiplies based on the number of enemies, his healing also suffers against ST, which Hyacine does not care for.

Hyacine generates a huge amount of Newbuds for Castorice, and even more with her E1. Hyacine also gives a 30% Max HP increase when her “After Rain” state is up, which directly increases all HP DPS damage.

Blade: Blade is the 2nd biggest benefactor of Hyacine (E0S1). Hyacine’s signature will consume Blade’s HP on his turn, giving him a stack of his talent, quickening the speed he acquires Charge. Together with the 3.4 buffs, Blade may have a bright future!

Mydei: Mydei still benefits from Hyacine, but arguably the least out of all the HP DPS. Hyacine’s sustaining is not the best numerically, and Mydei requires large amounts of healing, so you may find him losing Charge from not consuming enough HP from lack of sufficient sustain.

Feixiao / The Herta:

Hyacine is a sustain that attacks frequently with Little Ica, due to her high speed. Feixiao and The Herta gain “Energy” for their Ultimate from frequent attacks, and her damage contribution is much higher than Lingsha or Aventurine, two other sustains that attack often.

Little Ica’s attacks are full AoE too, so will generate a lot of Energy for The Herta against 5T.

Acheron:

With S1 Hyacine, Little Ica applies a Vulnerability debuff whenever it attacks, which means a stack for Acheron’s Slashed Dream. Hyacine attacks more frequently and can be more reliable than Aventurine/Lingsha for stack generation who are matchup dependent.

Harmony/Nihility

Tribbie: Tribbie is the go to support for HP characters, and it’s not surprising she’s great for Hyacine too. Her AoE buffs and field will make Little Ica do great damage without directly buffing Hyacine, letting the team focus on the main DPS, Hyacine’s 30% HP increase on her Ultimate will also increase Tribbie’s damage, as she scales off of HP too.

Sunday/RMC: When played as a sustain Hyacine will typically not be buffed, but Hyacine can be played as a DPS too, with triple supports similar to Lingsha. RMC and Sunday are prime supports, as they are the only characters that can directly apply buffs to memosprites.

Jiaoqiu/Ruan Mei/Pela:

These three do not discriminate against HP scaling characters, and their universal AoE ampe/debuff will help Little Ica do more destructive damage.

HSR Hyacine Teams

Castorice Dream Team

Castorice has received the perfect healer called Hyacine for her teams. Hyacine’s healing is full AoE including memosprites, which means Mem gets healed too. Castorice wants as much healing as possible, and Hyacine delivers that with her blazing 200+ SPD and frequent healing. Hyacine will quicken Castorice’s rotation, letting her spew out more dragons. Tribbie receives extra HP from Hyacine, increasing her own damage as well as providing passive on-field buffs for Little Ica so that RMC can fully focus on Castorice.

Blade’s Revival (?):

Blade has received a huge buff with Hyacine (E0S1), and with Tribbie+Sunday can finally be free from the shackles of ATK% focused harmony/support. Hyacine with her LC lets Blade get a stack of his Talent whenever it’s his turn due to the HP drain, letting Blade Cast Shufu’s Gift far more often. But this is not Blade’s final form! With the 3.4 Blade buffs, Blade may finally reach Paradise.

Not just for HP DPS:

Hyacine is not only good for HP DPS. She also benefits characters that gain Ultimate Charges or Energy from frequent attacks like Feixiao or The Herta. Little Ica attacks more often than other sustains, and can also apply a debuff with her Signature, helping Acheron. Little Ica’s damage also can’t be ignored, as it’s far higher DPS than any other sustain we’ve encountered so far.

A slight hiccup is that SP may become an issue, since Hyacine would prefer to skill whenever it’s her turn to maximize healing tally, which works fine with HP DPS since they normally don’t consume SP, whereas normal DPS do.

Hyacine Hypercarry

Yes, this works when facing AoE enemies. Similarly to Lingsha, Hyacine is capable of running triple supports and dishing out great damage, outrivaling many main DPS even. You won’t have to worry about dying too, and just focus on Little Ica terrorizing his enemies. This comp won’t perform as well against ST though, and would need extra help from support eidolons.

HSR Hyacine Pull Value and Conclusion

Hyacine is an amazing Remembrance sustain for HP DPS, and still works great for other teams. Her noticeable damage contribution, increased Max HP on allies, and frequent cleanse/healing makes her the best sustain in the game for the majority of the teams.

If you don’t have a limited sustain, she is a fantastic choice. However she is far from a must pull, especially if you have other sustain options. Just because she is the best, doesn’t mean that the other sustains can’t do their job either.

If you want to use Castorice at her full potential though, it is heavily recommended picking up Hyacine, as the difference in QoL and performance gain can be compared to when Acheron first received Jiaoqiu. When the AoE meta ends, Castorice will want the extra healing and damage from Hyacine to be able to power through ST or 2T scenarios, where Gallagher or other healers won’t be able to provide enough healing to gain Newbud.
