Hyacine
Yes—Hyacine is a top Remembrance partner/sustain. Ultimate “We Who Fly Into Twilight” restores HP across the threatened allies. Best with Castorice / Cyrene / Mydei. Built to enable HP-drain Remembrance cores. Skip when you’re not running Remembrance DPS.
Hyacine is a 5★ Wind Remembrance Main DPS. Skill “Love Over the Rainbow” is the primary in-combat spend. Ultimate “We Who Fly Into Twilight” is the payoff window for damage or team utility. This Phase 1 page covers kit text, gear targets, and pull notes—team comps stay empty until Phase 2.

Strengths
- Ultimate “We Who Fly Into Twilight” restores HP across the threatened allies—level this before polishing filler traces.
- Skill “Love Over the Rainbow” restores HP across the threatened allies—Outgoing Healing and HP relics convert directly into safer DPS turns.
- Talent “First Light Heals the World” fields a memosprite that acts as a second damage dealer—miss the stack conditions and the burst window feels empty.
- Hyacine’s memosprite/summon adds a second actor that hits and breaks without always spending the team’s Skill Points.
Weaknesses
- E0 without “Long May Rainbows Adorn the Sky” is still clearable, but the gap versus a signature copy is larger than a single eidolon for most Remembrance carries—plan the cone before deep eidolon hunting.
- If Energy or Skill Points starve “We Who Fly Into Twilight”, Hyacine spends turns on Basics and the kit’s advertised multipliers never show up on the combat log.
- Spamming “Love Over the Rainbow” every turn without watching Skill Points strands the rest of the team—Hyacine is often the SP sink.
- If “We Who Fly Into Twilight” is still offline at the end of a MoC cycle, the build is usually Energy/ERR or rotation order—not a missing CRIT roll.
Trace Priority
We Who Fly Into Twilight carries most of the kit’s damage or utility—level this first.
Love Over the Rainbow supports the main rotation—raise after the top priority traces.
First Light Heals the World supports the main rotation—raise after the top priority traces.
When Breeze Kisses Cirrus is last priority outside of filling trace materials.
Stat Priority
Open with Technique if it helps, spend Skill to advance the kit’s resource, and hold Ultimate for the damage or buff window. Exact teammate order lands in Phase 2.
Open supports first, then spend the carry’s Skill/Ult inside the buff window. Exact order varies by the team tab above.
Light Cones
5★ · Path cone
Increases the wearer's SPD by 0.18%. When the wearer uses Basic ATK, Skill, or Ultimate, consumes all allies' HP equal to #2[f1]% of their current HP, and after the next attack of the wearer's memosprite, enables it to additionally deal 1 instance of Additional DMG equal to #6[f1]% of the total consumed HP to the attacked target, with the damage type based on the memosprite's type. Then, the total consumed HP is reset. When the wearer's memosprite uses Memosprite Skill, increases the DMG taken by all enemies by #4[f1]%, lasting for 2 turn(s). Effects of the same type cannot stack.
Why it works —Signature / best-in-slot when owned—passive lines up with Hyacine’s kit triggers.
5★ · Path cone
Increases the wearer's SPD by #1[f1]%. After the wearer uses Skill, increases the DMG dealt by all allies by 0.08%, lasting for 3 turn(s).
Why it works —Best accessible option for most accounts—raise superimposition when copies drop.
4★ · Path cone
Increases the wearer's CRIT DMG by 0.12%. When the wearer's memosprite uses an ability on an ally target, increases the DMG dealt by all ally targets by 0.08%, lasting for 3 turn(s).
Why it works —Budget path cone—fine while building the account.
4★ · Path cone
Increases the wearer's ATK by 0.16%. After the wearer uses Ultimate, increases the Basic ATK DMG dealt by the wearer and their memosprite by 0.2%, lasting for 3 turn(s).
Why it works —Budget path cone—fine while building the account.
Relics
Team Compositions
Primary Remembrance / HP team for Hyacine. Castorice, Cyrene, Luocha are the partners the kit / endgame clears assume first.
Core carry for this shell — owns the damage plan and sets the rotation pace.
Castorice is the damage seat in this shell — build the supports around their rotation, not the reverse.
Cyrene is the damage seat in this shell — build the supports around their rotation, not the reverse.
Luocha covers HP / memosprite upkeep so the Remembrance loop does not collapse mid-wave.
Traces & Eidolons
Traces
Deals Wind DMG equal to 70% of Hyacine's Max HP to one designated enemy.
Summons memosprite Little Ica. Restores HP equal to 10.0% of Hyacine's Max HP plus 205 for all allies (except Little Ica), and restores HP equal to 12.5% of Hyacine's Max HP plus 256 for Little Ica.
Summons memosprite Little Ica. Restores HP equal to 12.5% of Hyacine's Max HP plus 256 for all allies (except Little Ica), and restores HP equal to 15.0% of Hyacine's Max HP plus 308 for Little Ica. Hyacine enters the "After Rain" state, lasting for 3 turn(s). This duration decreases by 1 at the start of Hyacine's every turn. While "After Rain" is active, all ally targets increase their Max HP by 37.5% plus 769.
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 100% for 2 turn(s). Stacks up to 3 time(s).
When the next battle starts, restores HP by an amount equal to 30% of Hyacine's Max HP plus 600 for all allies and increases Max HP by 20%, lasting for 2 turn(s).
Eidolons
While Hyacine is in the "After Rain" state, all ally targets additionally increase their Max HP by 50%, and after using an attack, immediately restore their HP by an amount equal to 8% of Hyacine's Max HP.
Is it worth getting?
Modest E1: While Hyacine is in the "After Rain" state. Helpful padding, not a build-defining unlock.
When an ally target's HP decreases, SPD increases by 30%, lasting for 2 turn(s).
Is it worth getting?
Stat-leaning E2: Flat combat-stat bump tied to a specific trigger. Clear damage, but it does not rewrite Hyacine’s rotation the way a mechanic eidolon would.
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.
Is it worth getting?
Ultimate + Skill + Basic ATK levels only (+2). Free if you roll into it; never spend currency aiming for E3.
The "Tempestuous Halt" Trace gets enhanced: For every 1 excess SPD, additionally increases Hyacine's and Little Ica's CRIT DMG by 2%.
Is it worth getting?
Side-grade: Flat combat-stat bump tied to a specific trigger. Happy if it drops; not a planned stopping point.
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.
Is it worth getting?
Skill + Talent levels only (+2). Skip as a goal—grab it if you overshoot toward E6, never hard-pity for it.
When Little Ica uses Memosprite Skill, the amount cleared from the tally of healing is changed to 12%. While Little Ica is on the field, all ally targets' All-Type RES PEN increases by 20%.
Is it worth getting?
Whale ceiling: Adds RES PEN (or ignore) during the burst window. Only chase if Hyacine is your dedicated Remembrance main and E0–E2 already feel finished.
Hyacine is fully usable at E0. Dedicated mains often stop at E0 before chasing higher. First stop: E0. Endgame target: E0.
