Hyacine — a 5-star Wind element character on the Path of Remembrance in Honkai: Star Rail. With high Speed, strong healing and a unique Memosprite companion, Hyacine blends sustain, utility and surprisingly solid damage potential. This guide dives into how to build her for effective performance: best Light Cones, relics, stat priorities, team synergies, and trace/talent upgrades.

Character Overview

• Hyacine’s main role is sustainer / healer, but she also contributes damage via her Memosprite “Little Ica.”
• She excels when built with high Speed and decent HP because some of her mechanics scale off Max HP.
• Her kit has multiple layers: healing, buffing allies’ max HP, generating Ica turns, debuffing enemies via her Light Cone and Memosprite.

Stat Priorities & Sub-stats

Main Stats to focus on:

• Speed (SPD): Crucial for Hyacine. Many guides list a minimum breakpoint of ~200 SPD to unlock her bonus Outgoing Healing and full Memosprite potential.
• HP % / Max HP: Because her healing, damage and many mechanics scale off Max HP.
• Outgoing Healing Boost (on Body relic) / HP% (on Sphere) / Energy Regen Rate (on Link Rope) or HP% depending on build.

Sub-stat priority:

• SPD >> HP% >> Crit DMG (on some builds) >> Effect RES (to avoid being disrupted)
• Note: Crit Rate is less important because Hyacine’s Memosprite often has 100% Crit Rate in certain states.

Recommended numeric targets (for end-game):

• SPD: ~200+ (ideally more if aiming for higher healing/damage)
• HP: 4,000-5,000+ base (before combat) depending on relic rolls.
• Crit DMG: Enough to boost her Ica damage; specific value depends on build but >50% is decent.

Best Light Cones

Top Pick:

• Long May Rainbows Adorn the Sky (5★) – Signature Light Cone. Increases SPD significantly + allows HP consumption from allies and subsequent Memosprite damage + applies a team-wide vulnerability buff.

Great Alternatives:

• Memory’s Curtain Never Falls (5★) – More accessible, gives SPD and after Skill use, increases all allies’ DMG.
• Victory in a Blink (4★) – Budget choice, gives SPD and Crit DMG buff for Hyacine; acceptable if you lack 5★ Light Cones.

elics & Planar Ornaments

Recommended Relic Sets:

• Warrior Goddess of Sun and Thunder (4-piece) – boosts SPD and gives Crit DMG buff to allies when Hyacine heals.
• Messenger Traversing Hackerspace (4-piece) – also good if you want higher SPD; less Crit support but helps speed ceiling.
• Mixed option: 2-piece of above + other SPD or Healing set if you don’t have full set.

Planar Ornaments:

• Giant Tree of Rapt Brooding (2-piece) – gives SPD bonus when above threshold + Outgoing Healing boost.
• Broken Keel – secondary option if you want to boost Crit DMG for allies.

Main stat placements:

• Body: Outgoing Healing % or HP %
• Feet: SPD
• Planar Sphere: HP %
• Link Rope: Energy Regen Rate (to help her gain turns) or HP % depending on resource availability

Sub-stats to prioritize:

• SPD
• HP%
• Crit DMG (especially if your Ica can deal damage)
• Effect RES (to avoid being silenced or controlled)

Best Team Compositions & Synergies

Hyacine is extremely versatile, working as both a core healer/support and a secondary damage contributor via her Memosprite. Here are recommended teams:

Team A – Hyper-HP/DPS Synergy (Ideal):

• Hyacine (Support/Healer)
• Castorice (Main DPS) – Because Hyacine’s HP buff and healing amplify Castorice’s HP-scaling kit.
• DPS/Burst unit (e.g., Mydei or other HP/DPS scaler)
• Utility/Support (buffs, shields or resource regen)

Team B – General Sustain & Mixed DPS:

• Hyacine
• DPS (any high output unit)
• Sub DPS or Support (helps apply buffs or removals)
• Another Support or Healer (depending on content)

In this composition, Hyacine fills the healing + utility role, while others focus purely on DPS. She ensures survivability and buff presence.

Team C – Casual / F2P Friendly:

• Hyacine
• Single strong DPS you have
• Two versatile supports (buff + utility)
  You may not hit perfect synergy, but Hyacine’s sustain will carry you through many content types.

Synergy Notes:

• Hyacine’s kit benefits from characters that can either scale off ally max HP or benefit from her buffs (like HP% increase from her Ultimate) so HP-heavy comps synergize well.
• Her Speed ensures she acts early, refreshing healing or buff windows before heavy threat phases.
• Because her Memosprite can deal damage and apply debuffs, she brings both utility and secondary DPS value in one package.

Trace & Talent Priority

• Ultimate (We Who Fly Into Twilight): Prioritize this first because it gives the “After Rain” state, increasing allies’ max HP for 3 turns
• Memosprite Talent & Skill: These govern Little Ica’s behaviour and damage/healing synergy
• Skill (Love Over the Rainbow): Important for the initial heal + summon Memosprite.
• Talent / Basic Attack: Lower priority; her damage primarily comes from Memosprite.

Final Thoughts

Hyacine stands out as one of the top healing/support units in Honkai Star Rail thanks to her Speed-driven healing, buffing mechanics, and unique Memosprite damage contributions. Whether you’re running HP-scaling DPS teams or general content, she offers massive flexibility and value. If you’re planning to pull her during a rerun banner, this build will help you maximise her potential from day one.
