Honkai Star Rail Cyrene Build Guide for Relics and Team comps

HSR Cyrene Build Guide: Best Relics, Light Cones, and Teams

Cyrene arrives as the final Chrysos Heir with a kit that feels less like a traditional support and more like a conductor standing in front of an entire orchestra. She does not simply buff and leave. She sets tempo, feeds turns, amplifies burst windows, and asks the rest of the team to move in rhythm with her. That alone makes her one of the most unusual Build projects in Honkai: Star Rail.

What really changes with Cyrene is how players think about support investment. Most supports in Star Rail are judged by one clean snapshot—speed breakpoint reached, buff active, rotation solved. Cyrene is different. Her value grows as your team takes more actions, as more memosprites enter the field, and as her Recollection economy starts looping back into itself. Building her well is not just about stats. It is about designing an entire team around how quickly she can reach her first Ultimate and how often she can keep that song going afterward.

Cyrene Overview: What She Actually Does in Battle

Cyrene is a 5-star Ice character on the Path of Remembrance, and the first thing that makes her stand out is that she fights alongside her memosprite, Demiurge. That immediately places her in a different category from standard Harmony-style supports, because her kit is split between her own actions, her memosprite’s actions, and the way both of them interact with the rest of the team.

At her core, Cyrene is a support who wants to do three things:

• reach her first Ultimate as early as possible

• create repeated value through Recollection generation

• turn fast, active teams into much stronger teams

She does this through a unique resource system called Recollection, which replaces normal Energy. Her first Ultimate requires 24 Recollection points, while the second and later Ultimates only require 12. That first threshold is the real gate. Once you pass it, Cyrene becomes dramatically smoother.

She also gains special value in teams filled with Chrysos Heirs or Remembrance characters, because those allies help her start with more Recollection and generate more of it during combat. That is why Cyrene feels merely good in mixed teams, but often feels exceptional inside dedicated Remembrance cores.

Cyrene’s Core Mechanic: Recollection, Future, and Why Speed Matters So Much

Cyrene’s combat loop revolves around one simple question: how fast can you get to the first Ultimate?

She begins battle with Recollection points based on team composition:

• from Chrysos Heirs: 1 / 2 / 3

• from Remembrance allies: 2 / 3 / 6

This immediately pushes her toward Remembrance-heavy teams, because the difference between entering a fight at 3 points and entering it at 6 points is enormous when you are trying to hit 24 as early as possible.

From there, her own actions add more:

• Basic ATK grants 1 point

• Enhanced Basic ATK grants 3 points

• Skill grants 3 points

Then comes the mechanic that makes her scale so hard with active teams: Future.

When combat begins, or after Cyrene acts, all allies and their memosprites gain Future. When they act, they consume Future and generate more Recollection for Cyrene. In other words, Cyrene rewards teams that are constantly taking actions, constantly refreshing tempo, and constantly cycling through turns.

This is why Speed is not a luxury stat on her. It is the foundation of the build. More Speed means:

• more Cyrene turns

• more Future application

• more Recollection income

• earlier first Ultimate

• more follow-up Ultimates after the loop starts

Her first Ultimate is also uniquely loaded. It can be cast twice under that first major setup and summons Demiurge while granting extra turns and immediately activating ally Ultimates. After that, the later Ultimates are smaller, cheaper, and far easier to cycle—but the first cast is the point where the fight changes.

Trace Priority: What to Level First

Cyrene is one of those characters whose upgrade order matters more than usual, because not all of her value is packed into one button.

Best Trace Priority

Memosprite Skill > Skill > Talent / Ultimate > Basic ATK / Memosprite Talent

That order matters for a reason.

Memosprite Skill

This is the first thing you max because it is the most important part of her real combat value. If you are building Cyrene seriously and leaving this behind, the whole build loses shape.

Skill

Her Skill is next because it directly affects one of the strongest buffs she provides, especially the True DMG support she brings into stronger comps.

Talent and Ultimate

These come next because they improve her resource flow, utility, and the impact of the Ult cycle itself.

Basic ATK and Memosprite Talent

These are still useful, but they are cleanup upgrades rather than priority upgrades. You level them because Cyrene does enough incidental damage and utility that the extra stats are welcome, not because they define the build.

Material Snapshot: What It Takes to Finish Cyrene

Cyrene is not cheap to finish, and like most premium support builds in late Star Rail, she asks for a lot of stamina before she starts feeling “done.”

Major materials

• Daythunder Anamnesis x12

• Sea Siren’s Torn Fin x65

• Flower of Ālaya x139

• Tracks of Destiny x8

• Credits x3,888,100

And that is before counting the usual trace material chain and EXP books.

The biggest practical takeaway is that Flower of Ālaya is the most stamina-hungry part of the farm, so if you are prefarming Cyrene, that is usually the material to plan around first.

Best Relic Build: Stats First, Set Second

Cyrene’s relic philosophy is very straightforward: the right stats matter more than the perfect set.

That is especially true because Cyrene wants to reach a high Speed threshold, and high-Speed builds are notoriously awkward to finish cleanly. If your best “ideal” set leaves her under the breakpoint, it is not actually your best set.

Best-in-Slot Relic Set

Deliverer’s Hood

2-Piece: Increases CRIT Rate by 8%
4-Piece: After the wearer uses Basic ATK or Skill, if the memosprite is on the field, increases Max HP of the wearer and memosprite by 24%, and increases all allies’ dealt DMG by 15% until after the wearer’s next Basic ATK or Skill

This set fits Cyrene’s design beautifully.

She wants:

• HP scaling

• frequent actions

• memosprite uptime

• party-wide damage value

Deliverer’s Hood gives all of that in one package. It smooths stat requirements while turning her normal turn flow into a constant team-wide offensive aura.

Best Planar Ornament

Amphoreus, The Eternal Land

2-Piece: Increases the wearer’s CRIT Rate by 8%. While the wearer’s memosprite is on the field, increases all allies’ SPD by 8%.

This is the planar set that makes Cyrene feel the most complete. The CRIT Rate helps support her sub-DPS side, but the real value is the party-wide SPD boost while the memosprite is active. That is exactly the kind of “tempo multiplies tempo” effect her kit wants.

This set does not just improve Cyrene. It improves the engine around her.

Best Alternative Relic Setup

If your Deliverer’s Hood pieces do not give enough Speed, the safer route is often:

• 2pc Messenger’s Holovisor

• 2pc Sacerdos’ Relived Ordeal

Each gives SPD +6%, and together they make hitting the crucial Speed thresholds much more realistic.

This is often the better choice for lower-investment accounts, because Cyrene would rather wear a weaker set at the correct Speed than a stronger set at the wrong Speed. Her third major trace and overall loop care too much about tempo for you to ignore that.

Alternative Ornament Options

If Amphoreus is unavailable or your substats are much better elsewhere, there are two acceptable alternatives:

Bone Collection’s Serene Demesne

Gives more HP and, if she reaches 5000 HP, grants strong CRIT DMG to both Cyrene and her memosprite.

This is the more offensive alternative.

Giant Tree of Rapt Brooding

Provides SPD and additional healing-related value at higher Speed thresholds.

This is more of a utility fallback and is still usable, but Amphoreus is the cleaner recommendation in most builds.

Main Stats and Sub Stats: How to Build Her Properly

Cyrene’s stat priorities are more specific than they first appear.

Main Stats

• Body: CRIT DMG / HP%

• Boots: SPD

• Sphere: HP% / Ice DMG%

• Rope: HP%

Why CRIT DMG Body?

Cyrene already gets 50% CRIT Rate from her Ultimate, which means CRIT DMG Body is usually the stronger value option unless your relic quality forces something awkward.

Why HP% Sphere and Rope?

Because Cyrene is not just trying to do personal damage. HP scales extremely well with her overall role, especially in teams where the added utility and charge generation matter more than squeezing a slightly prettier damage number from the Sphere slot.

Ice DMG Sphere is still fine, but HP% is generally the more practical choice, especially in Castorice-focused setups.

Sub Stat Priority

SPD > CRIT Rate / CRIT DMG > HP

That is the real order.

Speed is not “nice to have.” It is the stat you chase first, hardest, and longest.

After that, you want enough CRIT support to make her sub-DPS contribution look respectable, then extra HP to strengthen the overall structure of the build.

Recommended Endgame Stats

The build target that matters most is Speed.

Practical target

• 180 SPD minimum

• 200 SPD if possible

Hitting 180 is important because it unlocks the trace threshold the build is really centered around. Pushing beyond that into 190–200 territory is not mandatory, but it meaningfully improves how often Cyrene gets to refresh the loop and generate more Recollection.

Good F2P benchmark stats

• HP: around 6800+

• SPD: around 189+

• CRIT Rate: 30%+

• CRIT DMG: 160%+

That is a good realistic endpoint for non-whale builds. If you are near that line, the build is already healthy.

Best Light Cones: Signature, Herta Option, and Budget Value

Cyrene’s Light Cone choices follow the same logic as her relics: team utility beats selfish damage.

She wants Speed. She wants team buffs. She wants effects that keep the whole party’s output rising, not just her own.

Best-in-Slot Light Cone

This Love, Forever

Cyrene’s signature Light Cone is easily her best option.

It gives:

• SPD

• enemy damage vulnerability through Blank

• teamwide CRIT DMG through Verse

• stronger combined effects when both are active

This is exactly the kind of support cone you want on Cyrene, because it extends what she is already trying to do. It does not change her job. It makes her better at it.

If you want the cleanest and strongest version of Cyrene, this is the cone.

Strong Alternative: Herta Store Option

Memory’s Curtain Never Falls

This is one of the best fallback options because it still gives:

• SPD

• team-wide DMG buff after Skill use

It lacks the layered ceiling of the signature cone, but it remains a very strong and practical choice, especially for players who want a stable 5-star option without pulling extra.

Battle Pass Alternative

Victory In a Blink

This is the cost-effective choice.

It gives:

• CRIT DMG to the wearer

• team-wide DMG buff whenever the memosprite uses an ability on an ally

That aligns very naturally with Cyrene’s flow and keeps her performance relatively close to premium options, especially for players who are not chasing max optimization.

Signature Light Cone vs Eidolons: What Is Worth Pulling?

Cyrene is one of those characters where the answer depends on how deep you want to go.

Signature Light Cone (S1)

The main value:

• 18% SPD

• enemy vulnerability

• team CRIT DMG

• stronger full-kit support once both buff states are active

This is immediately valuable and easy to feel.

E1

Gives:

• extra Recollection generation

• additional bounce damage

• smoother post-Ult cycling

This is good, but it does not solve the most important early problem by itself.

E2

This is the real turning point.

It gives:

• 12 Recollection on entering combat

• stronger Skill True DMG buff

• dramatically faster first-Ult timing

Combined with E1, Cyrene can start absurdly fast and becomes far more comfortable in zero-cycle or speedkill-style setups.

If you are investing beyond base Cyrene, E2 is the most important Eidolon.

E4 and E6

These are luxury territory.

• E4 blows up her personal bounce damage

• E6 turns her into an even more outrageous team accelerator with action advance and DEF shred effects

These are powerful, but they are not part of a normal build recommendation.

Recommended pull priority

E0S0 > E1S0 > E2S0 > E2S1 > E6S1

That is the cleanest investment ladder for practical players.

Best Teams: Where Cyrene Actually Shines

Cyrene is not locked to one team, but she very clearly prefers lineups that let her Recollection system breathe.

The more actions your team takes, and the more memosprites are involved, the faster Cyrene becomes the centerpiece of the battle.

Best Team: Cyrene / Castorice / Evernight / Hyacine

This is one of the most natural homes for Cyrene.

Why it works:

• strong Remembrance synergy

• memosprites everywhere

• fast early Recollection generation

• Cyrene’s HP-focused gearing translates cleanly here

• Hyacine accelerates the action economy enough to help Cyrene cross the 24-point line early

This is the kind of team where Cyrene feels designed, not borrowed.

Phainon Team

Cyrene / Phainon / Cerydra / Dan Heng • Permansor Terrae
with support alternatives like Sunday, Tribbie, or Robin and sustain options like Huohuo, Hyacine, or Lingsha

This lineup leans harder into premium synergy and lets Cyrene operate as a high-end support bridge for a more explosive core.

Mydei Team

Cyrene / Mydei / Tribbie / Hyacine
with flexible fifth-slot concepts through supports or sustain replacements

This is a strong hybrid shell where Cyrene’s tempo value helps Mydei setups feel cleaner and less rigid.

Aglaea Team

Cyrene / Aglaea / Sunday / Hyacine
with Tribbie, Robin, or Ice Trailblazer as alternatives

This is another lineup where her support identity remains intact, but the payoff is more about tempo and layered buffs than about direct memosprite-centric flavor.

Anaxa Team

Cyrene / Anaxa / Tribbie / Hyacine
with Cerydra, Sunday, Ice Trailblazer, Dan Heng • Permansor Terrae, Lingsha, or Aventurine as flex choices

This setup shows Cyrene’s versatility. She is strongest in her natural home, but good enough to support more experimental or premium compositions as well.

How Cyrene’s Charge Generation Works in Practice

The easiest way to understand Cyrene is to look at a normal opening cycle.

At E0, she can start combat with around 6 Recollection from her passive if the team is built correctly.

Then:

• with 180 SPD, Cyrene usually gets 2 turns in the first cycle

• those actions add 6 more points

• a very fast ally like Hyacine may act 3 times

• Hyacine’s memosprite can also contribute

• the other allies add more through consumed Future

By the time the dust settles, Cyrene is often sitting very close to the 24-point threshold, and a few additional ally Ultimates usually finish the job.

In full Remembrance teams, it becomes even easier because memosprites keep adding value to the economy. That is why Cyrene often feels merely “solid” outside those teams and incredible inside them.

Blueprint: How to Build Cyrene the Right Way

Step 1: Fix Speed Before Anything Else

Do not chase the prettiest relic set first. Chase 180 SPD first.

Step 2: Build Her as a Support First, Sub-DPS Second

HP and tempo matter more than forcing flashy personal damage.

Step 3: Use Deliverer’s Hood if the Speed Is Good Enough

If it is not, fall back to 2pc + 2pc SPD.

Step 4: Put Her in Action-Heavy Teams

Cyrene gets stronger when allies act often and memosprites are active.

Step 5: Prioritize the First Ultimate

The whole fight changes once she crosses 24 Recollection. Build around getting there quickly.

Trailblazers preparing for Cyrene can start stronger with optimized Accounts, speed up relic and trace farming through expert Hourly Services, or accelerate endgame setup with trusted Boosting to get her battle-ready faster.

Cyrene is not a support you finish in one afternoon and forget. She is the kind of character who keeps getting better the more carefully you build around her. And once her first Ultimate starts landing on time, the rest of the team begins to feel like it is moving inside her poem.
