Cyrene is a 5-star Ice Remembrance support who summons Memosprite Demiurge, charges a resource called Recollection, and on her first Ultimate — fires all ally Ultimates simultaneously.
She buffs every Chrysos Heir with a unique personalised Ode buff tailored to each specific character’s kit. Castorice, Phainon, Evernight, Aglaea, and others each receive dedicated, individually designed bonuses.
Her A6 trace gives the entire team +20% DMG and scaling Ice RES PEN when Cyrene reaches 180 SPD — this is her most critical stat threshold.
She applies a 20% DEF reduction to all enemies on first Memosprite Skill use and provides a 12% True DMG Zone through her Skill — True DMG bypasses enemy DEF entirely.
Best Light Cone: This Love, Forever (her signature) — provides 18% SPD, 10% enemy Vulnerability, 16% ally CRIT DMG, and 60% amplification when both effects are active.
Best Relics: World-Remaking Deliverer (4-piece) + Amphoreus’ Eternal Land (Planar Ornament).
Best teams: Castorice / Evernight / Cyrene / Hyacine (premium Remembrance) and Cyrene / Phainon / Cerydra / Dan Heng • Permansor Terrae.
Do not activate Phainon’s Ultimate transformation until after Cyrene has fired her first Ultimate — Phainon’s transformation removes all allies, halting Recollection generation.
E1 is recommended before the signature LC — it adds 12 extra bounces to Demiurge’s Skill and grants 6 Recollection after each Ode application.
Cyrene debuted in Version 3.7 (November 2025) and last reran in Version 4.0 (February–March 2026). Watch for future reruns.

Who Is Cyrene in Honkai Star Rail?

Cyrene is a 5-star Ice character following the Path of Remembrance in Honkai Star Rail. She debuted in Version 3.7 (November 5, 2025) as the final Chrysos Heir of the Amphoreus arc and returned for a rerun in Version 4.0 (February 2026). As of patch 4.3, she is rated S+ tier in Remembrance and Chrysos Heir team compositions and is the most mechanically unique support character in the game.

In the game’s lore, Cyrene is the former holder of the Coreflame of Time who removed herself from Amphoreus’ world to become an observer — watching from just outside the simulations. Her identity is deeply entwined with Mem and the Remembrance Trailblazer. A meteor streaks across the night sky, sending ripples through the river of life, gleaming in thirteen hues. Daughter of Aedes Elysiae, Chrysos Heir who nourishes memory — her mission is to sow the Seed of Memory so that flowers of the past may bloom in tomorrow.

In gameplay, this manifests as Cyrene having individually designed passive buffs — called Odes — for every single Chrysos Heir in the Amphoreus storyline. Castorice gets one. Phainon gets one. Evernight gets one. Aglaea gets one. Every Chrysos Heir she shares a team with receives a specifically tailored benefit when Demiurge targets them — making her uniquely powerful in Amphoreus-era team compositions.

Cyrene Kit Overview – How Her Abilities Work

Cyrene’s kit is built on three interconnected systems: the Recollection resource that charges her Ultimate, the Demiurge Memosprite that applies her buffs and damage zones, and the Future mechanic that ties her allies’ actions to her own power generation. All three feed into each other, creating a support loop unlike anything else in HSR.

Recollection – The Core Resource

Recollection is Cyrene’s custom resource — she needs 24 points to activate her first Ultimate. The sources:

Basic ATK: 1 Recollection
Enhanced Basic ATK (after first Ultimate): 3 Recollection
Skill: 3 Recollection
Allies consuming Future stacks: 1 Recollection per ally action
Allied Memosprites acting: 1 Recollection per Memosprite action (Memosprites do not consume Future, but still generate)

In a full Remembrance team with Castorice, Evernight, and Hyacine all having active Memosprites, Recollection floods in from every direction simultaneously. In less Remembrance-heavy teams, it builds more slowly and requires more of Cyrene’s own Basic ATK and Skill actions.

Future – The Ally Mechanic

Future is a passive buff Cyrene grants to all allies when entering battle and refreshes it after each of her own actions. When an ally that has Future takes any action, they consume the stack and grant Cyrene 1 Recollection. This is what makes every ally action on the team simultaneously feed Cyrene’s charge meter. In fast-cycling teams with multiple characters taking turns, Recollection builds extremely fast purely through the Future system.

Basic Attack – Waltz of Flowers and Arrows

Deals Ice DMG equal to 50% of Demiurge’s Max HP to all enemies. Generates 1 Recollection. After Cyrene’s first Ultimate activates, this enhances to an Enhanced Basic ATK generating 3 Recollection. The enhanced version is the same ability but with a stronger multiplier and more Recollection. Always prefer Skill or Enhanced Basic ATK over the unenhanced version — the unenhanced Basic ATK is mostly for Recollection generation before the first Ultimate in early-battle situations.

Skill – Dreamer’s Lullaby

Creates a Zone that lasts for 3 turns. While the Zone is active:

On first activation, applies a 20% DEF reduction to all enemies. This is a team-wide multiplicative amplifier that stacks with RES PEN and vulnerability debuffs.
All ally attacks deal an additional 12% True DMG based on their original DMG. True DMG bypasses enemy DEF entirely — it is one of the rarest and most powerful damage types in the game.

Generates 3 Recollection. The Skill is your primary Recollection builder alongside the Future-consuming ally actions. Use it consistently to keep the Zone active and maintain the 20% DEF reduction and True DMG bonus on all allies simultaneously.

Ultimate – A Poem About Her Memosprite (First Cast)

When Cyrene activates her first Ultimate at 24 Recollection, three explosive things happen simultaneously:

Demiurge is summoned to the field with HP equal to 100% of Cyrene’s Max HP.
All other allies’ Ultimates are immediately activated — every teammate fires their Ultimate at once, regardless of their Energy status. This is the most dramatic opening burst in HSR and the reason Cyrene teams feel so powerful on the first cycle.
Cyrene enters Ripples of Past Reverie permanently for the rest of battle — reducing subsequent Ultimate costs from 24 to 12 Recollection.

The mass ally Ultimate activation is extraordinary value. Castorice’s Netherwing spawns immediately. Phainon loads Coreflame from Evernight’s Ultimate. Hyacine applies After Rain buffs. All in one turn, before any enemy acts. This opening burst is why Cyrene is so highly rated in content where the first cycle matters most.

Ultimate – Subsequent Casts (12 Recollection Each)

After the first Ultimate, every subsequent cast of her Ultimate grants Demiurge an extra turn to use its Memosprite Skill immediately. This means Cyrene’s subsequent Ultimates are effectively “deploy Demiurge’s Ode application now” buttons. Each cast also refreshes the 20% DEF reduction Zone and re-applies the True DMG amplifier.

Demiurge’s Memosprite Skill – Minuet of Blooms and Plumes

Demiurge targets one ally and applies a personalized Ode buff — or targets one enemy for a damage hit if no appropriate Chrysos Heir is present. The Ode system is Cyrene’s defining feature:

Ode to Castorice: Grants Castorice Overflow — any Newbud generation beyond max becomes double-counted for Netherwing consumption damage. Also boosts Castorice’s ability output.
Ode to Phainon: Grants Phainon +6 Coreflames (accelerating his transformation), +12% CRIT DMG, +16% CRIT Rate, and +4 Scourge stacks for Khaslana.
Ode to Evernight: Grants Evernight +9% Dream DMG with Memoria generation enhancements.
Ode to Aglaea: Provides one-time +70 Energy, 72% DMG amplification, and 36% DEF ignore for Aglaea.
Ode to Dan Heng • Permansor Terrae: Grants the Bondmate a 24% DMG buff, advances Souldragon’s action by 100%, and gives an enhanced Shield.
Ode to Hyacine: Boosts healing output and provides additional Ode stacks to the team.
Generic Ode (non-Chrysos Heir): When targeting any non-Chrysos Heir ally, Demiurge applies a flat 40% DMG increase to that ally. This still provides meaningful support for characters like Sunday or Tribbie, but it is noticeably less impactful than the tailored Odes.

Talent – Story System

When Cyrene uses her Ultimate or when Demiurge is summoned, Demiurge gains 1 Story point. When Story reaches 3, Demiurge consumes all stacks to immediately take an extra turn and auto-cast its Memosprite Skill. This gives Demiurge additional Ode applications beyond what Cyrene’s Ultimates trigger manually — particularly important in longer fights where you need Ode refreshes between Ultimate casts. Demiurge also gains an extra Ice DMG instance when all allies have contributed Recollection, making full Remembrance teams additionally rewarding.

A4 Trace – Ripples Across Time

Cyrene starts battle with additional Recollection based on her team composition:

1 Chrysos Heir or Remembrance character besides Cyrene: +2 Recollection
2 such characters: +4 Recollection
3 such characters: +6 Recollection

In a full Remembrance team (Castorice, Evernight, Hyacine), Cyrene starts battle with 6 Recollection pre-loaded — plus the 3 from her first Skill use puts her at 9 before any Future stacks fire. The first Ultimate arrives dramatically faster. Unlock A4 as your first priority.

A2 Trace – Child of Remembrance

Allied Memosprites’ Future stacks are never consumed. Instead of a Memosprite action consuming Future and granting 1 Recollection, Memosprites still grant Recollection but keep the Future stack intact for the next use. This prevents the Recollection engine from “running dry” in multi-Memosprite teams and effectively means every Memosprite action generates Recollection permanently without ever depleting Future charges.

A6 Trace – Causality in Trichotomy (The 180 SPD Breakpoint)

This is Cyrene’s most important trace and the reason SPD is her top stat priority. When Cyrene’s SPD reaches 180:

All allies deal +20% more DMG — a team-wide multiplicative amplifier permanently active from the moment her SPD hits the threshold.
Cyrene and Demiurge gain Ice RES PEN equal to +2% per point of SPD above 180, up to a maximum of 120% at 240 SPD.

Every point of SPD above 180 simultaneously makes Cyrene act more frequently AND scales the team’s RES PEN upward. At 200 SPD, she is providing 40% Ice RES PEN. At 220 SPD, 80%. The value of SPD substats on Cyrene is disproportionately large compared to any other stat — each SPD roll is simultaneously a rotation accelerator and a team DPS amplifier.

Technique – Peace at West Wind’s End

Creates a Dimension for 30 seconds in the overworld. Enemies inside the Dimension cannot take actions (effectively frozen in place), and all allies gain 50% SPD. Upon entering battle from the Technique state, Cyrene deploys her Zone immediately and all allies receive a buff. Always use the Technique before fights — the pre-deployed Zone means the 20% DEF reduction and True DMG bonus are active from the very first turn.

Cyrene Best Light Cones in HSR

Cyrene follows the Path of Remembrance. The Remembrance pool is relatively limited, making Light Cone choices more constrained than older paths. Her signature is the clear best option — and crucially, it provides 18% SPD, which dramatically eases reaching the critical 180 SPD breakpoint.

This Love, Forever (Signature – Best in Slot)

Cyrene’s dedicated 5-star signature is best-in-slot and the most important single upgrade for her build. It provides 18% SPD — the single most valuable stat for Cyrene, as it makes reaching 180 SPD reachable with moderate substat investment rather than requiring near-perfect speed rolls. Beyond SPD, the signature grants two stacking passive effects that trigger from Demiurge’s Memosprite Skill: Blank (enemies take 10% increased DMG from all sources) and Verse (all allies gain 16% CRIT DMG). When both Blank and Verse are active simultaneously, both effects are amplified by 60%, bringing the active bonuses to roughly 16% enemy vulnerability and 25.6% ally CRIT DMG. Community testing puts S1 This Love Forever at 100% relative performance and S5 F2P options at 86–88%. If you pull Cyrene, pulling her signature on the same banner is highly recommended.

Long May Rainbows Adorn the Sky (Hyacine’s Signature – 96% Relative Performance)

Hyacine’s signature Light Cone is the strongest alternative if you already own it. It provides 18% SPD — the same speed bonus as Cyrene’s own signature — meaning it solves the 180 SPD problem equally well. The other effects (HP drain and healing-related passive) are less relevant for Cyrene’s support role but the SPD alone makes this highly competitive. Rated at 96.29% relative performance vs the signature in community testing.

Memory’s Curtain Never Falls (Herta Store – Best F2P Option)

The best free-to-play Light Cone for Cyrene, obtainable from the Herta Store with Herta Bonds. It provides SPD%, which directly contributes toward the 180 SPD threshold. At S5, this is rated at 86.17% relative performance — meaningfully below the signature but far more accessible. Prioritise getting this to S5 while saving for the signature on a future rerun. The SPD bonus is the critical feature here.

Victory In a Blink (4-Star Battle Pass – 88% Relative Performance)

A 4-star Battle Pass Light Cone that provides CRIT DMG and is competitive at S5, rated at 88.19% relative performance. The CRIT DMG contributes to Cyrene’s Verse effect through better base stats. A strong option for players with Battle Pass access and lacking the signature.

Cyrene Best Relics in HSR

Cyrene’s relic strategy is almost entirely dedicated to one goal: reach 180 SPD. Every decision — set choice, main stat selection, substat priority — serves that threshold first. After 180 SPD is achieved, the remaining investment goes into CRIT Rate (for Demiurge’s damage and stability), CRIT DMG, and HP (which scales Demiurge’s Max HP and some ability multipliers).

Best 4-Piece Relic Set: World-Remaking Deliverer

This is Cyrene’s best-in-slot relic set. The 2-piece provides CRIT Rate, helping stabilize Demiurge’s hits and Cyrene’s own damage. The 4-piece is the key: after using Basic ATK or Skill, Cyrene’s Max HP increases by 24% (scaling Demiurge’s HP since it equals 100% of Cyrene’s Max HP) and all allies’ DMG increases by 15% while Demiurge is on the field. The ally DMG bonus from the 4-piece effectively provides a permanent team DPS multiplier during any fight where Demiurge is active — which is essentially every fight once the first Ultimate fires. Farm this set specifically for Cyrene.

Alternative: 2-Piece SPD Set Combination

While farming for a complete World-Remaking Deliverer set, running two different 2-piece sets that each provide SPD bonuses is a strong interim option. Combining Messenger Traversing Hackerspace (2-piece SPD) with Warrior Goddess of Sun and Thunder (2-piece SPD) gives double SPD bonuses, dramatically easing the 180 SPD threshold without needing a complete 4-piece set. This is the recommended transitional build until you have clean World-Remaking Deliverer pieces with good substats.

Best Planar Ornament: Amphoreus’ Eternal Land

Cyrene’s best Planar Ornament. The 2-piece provides CRIT Rate, helping stabilize Demiurge’s damage. It also gives Cyrene’s Memosprite a significant SPD bonus — making Demiurge act faster even though Demiurge has 0 base SPD, this bonus pushes Demiurge’s effective action frequency upward for Story stack generation. The combined CRIT Rate and Memosprite SPD make this the optimal Planar set.

Alternative Planar Ornament: Sprightly Vonwacq

Provides Energy Regeneration Rate and Action Advance for the wearer at 120+ SPD. The action advance gives Cyrene an extra turn at battle start once she hits 120 SPD — something she achieves without heavy investment. A solid alternative if you have excellent Vonwacq pieces with strong SPD substats and are still farming Amphoreus’ Eternal Land.

Relic Main Stats to Target

Head: HP (fixed)
Hands: ATK (fixed — largely irrelevant for Cyrene’s support function)
Body: HP% (most common recommendation) or CRIT DMG (if SPD threshold is already comfortably met and CRIT Rate is secured)
Feet: SPD — mandatory. Every point of SPD above 180 also provides Ice RES PEN through A6. Never run any other main stat here.
Planar Sphere: HP% (scales Demiurge’s Max HP and Cyrene’s survivability) or Ice DMG Bonus (secondary option once HP is sufficient)
Link Rope: HP% (for Demiurge HP and survivability). Energy Regeneration Rate is less critical since Cyrene uses Recollection rather than standard Energy.

Key Substat Priority

SPD is the top priority for substats — stack SPD until you comfortably exceed 180 in combat. CRIT Rate is next to ensure Demiurge’s hits crit reliably and to stabilize the Verse CRIT DMG buff’s value. CRIT DMG contributes to Demiurge damage and the Verse buff indirectly. HP% scales Demiurge’s Max HP and some of Cyrene’s own ability multipliers. Avoid ATK% entirely.

Stat Targets

SPD: 180+ in combat (critical threshold for A6 activation). 200+ ideal; 240 maximizes Ice RES PEN.
HP: 4,000–5,000+ (Demiurge HP = 100% of Cyrene’s Max HP)
CRIT Rate: 30%+ (stability for Demiurge’s hits)
CRIT DMG: 100%+ (improves Demiurge damage output and Verse buff impact)

Cyrene Best Teams in HSR 4.3

Cyrene’s peak value is in full Remembrance teams or Chrysos Heir compositions. The Ode system means her contribution per slot is dramatically higher when she is surrounded by Amphoreus characters. Outside these archetypes, she provides only the generic 40% DMG Ode and the 12% True DMG Zone — strong but less uniquely impactful.

One critical anti-synergy to know before team-building: Phainon’s Ultimate transformation removes all allies from the field. While allies are in the Departed state during Khaslana’s 8-turn window, Future stacks cannot be consumed, Cyrene cannot act, and Recollection generation completely halts. If running Phainon alongside Cyrene, never let Phainon use his transformation Ultimate until after Cyrene’s first Ultimate has fired and his Ode is applied. Plan rotations accordingly.

Premium Remembrance Team: Castorice / Evernight / Cyrene / Hyacine

This is the best Remembrance team in the game and Cyrene’s peak composition. Castorice receives Ode to Castorice from Demiurge — enabling Overflow mechanics that double-count Newbud generation beyond capacity for Netherwing damage amplification. Evernight receives Ode to Evernight, boosting her Dream DMG and Memoria generation. Hyacine receives Ode to Hyacine, boosting healing and providing extra Ode stacks. Every character in the team generates Recollection through Future stacks — Netherwing’s actions, Evey’s actions, Little Ica’s actions — creating a flood of Recollection on every turn cycle. The combined A6 RES PEN from Cyrene (20%+ at 180 SPD) and Evernight’s own 20% RES PEN brings the total team RES PEN to 40%+ from support slots alone. The recommended Eidolon investment for this team is E0S1–E2S1 Castorice / E1S1 Evernight / E1S1 Cyrene / E1S1 Hyacine.

Phainon Hypercarry Team: Phainon / Cyrene / Cerydra / Dan Heng • Permansor Terrae

Phainon receives one of the strongest individual Odes in the game — +6 Coreflames (accelerating transformation), +12% CRIT DMG (raising total CRIT DMG to 72% with trace bonuses), +16% CRIT Rate, and +4 Scourge stacks for Khaslana. Cerydra provides Military Merit buff, Peerage state, and Skill DMG amplification for Phainon. Dan Heng • Permansor Terrae handles shields, ATK buffs, and receives Ode to Permansor Terrae giving Souldragon 100% action advance. The key rotation rule: hold Phainon’s Ultimate until Cyrene’s first Ultimate has fired and Ode to Phainon is applied. After the Ode is active, Phainon transforms with full buffs already loaded — and those buffs snapshot into his 8-turn Khaslana window.

Aglaea Hypercarry Team: Aglaea / Sunday / Cyrene / Hyacine

Aglaea receives Ode to Aglaea — a one-time +70 Energy, 72% DMG amplification, and 36% DEF ignore. The 70 Energy alone covers half of her 350-cost Ultimate in a single Ode trigger. Sunday provides Action Advance and CRIT DMG buffs for both Aglaea and Garmentmaker. Cyrene’s first Ultimate activates Aglaea’s and Sunday’s Ultimates simultaneously — setting up an extraordinary opening burst. Hyacine heals and applies After Rain Max HP buff.

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

Replacing Evernight with Trailblazer (Remembrance) makes this team more accessible for players without Evernight. RMC’s Mem still contributes Recollection generation through Future stacks, provides True DMG amplification, and gives Castorice CRIT buffs. Cyrene’s Ode to Castorice still applies. Hyacine sustains. This is a strong mid-investment Remembrance team that works without pulling Evernight.

Budget Chrysos Heir Team: Cyrene / Phainon / Trailblazer (Remembrance) / Dan Heng • Permansor Terrae

An accessible Phainon team that includes Cyrene. Trailblazer (Remembrance) provides True DMG, CRIT buffs, and Mem’s Recollection generation. Dan Heng • Permansor Terrae handles sustain with shields and ATK buffs for Phainon. Cyrene provides Ode to Phainon and the True DMG Zone. Remember to hold Phainon’s transformation until Cyrene’s first Ultimate fires.

Non-Chrysos Heir Teams (Lower Priority)

Outside Chrysos Heir and Remembrance archetypes, Cyrene provides the generic 40% DMG Ode and 12% True DMG Zone. While these are useful, characters like Robin, Ruan Mei, or Tribbie generally outperform Cyrene’s support contribution in non-Amphoreus teams. Consider Cyrene specifically for Chrysos Heir teams and Remembrance compositions — for other team archetypes, other supports are often stronger value.

Cyrene Trace Priority

Invest your upgrade materials in this order:

Major Trace A4 – First and most urgent. Ripples Across Time grants +2/4/6 starting Recollection based on Chrysos Heir and Remembrance allies. This directly reduces the number of turns needed to reach the first Ultimate. In a full Remembrance team, starting with 6 Recollection means the first Ultimate fires in roughly half the time it would take at E0 without this trace. Unlock immediately.
Major Trace A6 – Second. Causality in Trichotomy is the 180 SPD passive that grants +20% team DMG and scaling Ice RES PEN. This is the single most impactful passive for team output and must be unlocked as soon as ascension materials allow.
Major Trace A2 – Third. Child of Remembrance prevents Allied Memosprites from consuming Future stacks, enabling permanent Recollection generation from Memosprites. Essential for full Remembrance teams. Unlock after A4 and A6.
Memosprite Skill – Level fourth. Demiurge’s Minuet of Blooms and Plumes governs the damage output and Ode application power. Higher level increases Demiurge’s hit multipliers and strengthens individual Ode effects. Primary active damage source.
Skill – Fifth. Higher Skill level increases the True DMG percentage in the Zone (12% at base, scaling up with level) and the Recollection generation value. Every level directly amplifies the team’s damage output.
Ultimate – Sixth. Higher Ultimate level increases the ally Ultimate activation power and some Demiurge summon stats. Less impactful per level than Skill and Memosprite Skill but still worth leveling.
Talent and Basic Attack – Last. The Talent governs Story stack generation and some Demiurge bonuses. Basic ATK generates only 1 Recollection per use. Both are lower priority than everything above.

Cyrene Eidolons – Which Ones Are Worth It?

Cyrene is functional at E0 in full Remembrance teams but struggles to reach 180 SPD without the signature LC at E0S0. E1 is the priority investment — not only for damage but for rotation consistency.

E1 – Best Value Eidolon (Recommended Over Signature for First Investment)

E1 provides two significant improvements:

After each Ode application from Demiurge’s Memosprite Skill, Cyrene immediately gains 6 additional Recollection. This dramatically accelerates her subsequent Ultimate cycles — the second and third Ultimates arrive much faster after the first.
Demiurge’s Memosprite Skill gains 12 additional bounces per cast. More bounces means more individual hits, more True DMG zone triggers, and more total damage per Demiurge action.

Community consensus rates E1 as a higher priority investment than the signature Light Cone for Cyrene. The rotation acceleration from +6 Recollection per Ode and the damage increase from +12 bounces compound across the entire fight duration. Recommendation: pursue E1 first, then signature LC.

E2 – Rotation Fix + True DMG Amplification

E2 grants Cyrene 12 Recollection at battle start — effectively halving the Recollection needed for the first Ultimate from 24 to 12. This means the first Ultimate fires in roughly 2–3 turns in any team composition, regardless of Remembrance ally count. E2 also increases the True DMG multiplier in the Skill Zone from 12% to a higher value. The 12 starting Recollection particularly benefits non-Remembrance teams where the Future generation is slower. Community estimates put E2 at enabling near 0-cycle potential with ideal team coordination. For dedicated Cyrene players, E2 is the recommended stopping point.

E4 – Personal Damage Ramp

Each time Demiurge uses Minuet of Blooms and Plumes, the bounce DMG multiplier increases by 6% in the current battle (up to 24 stacks). In longer fights, this ramp makes E4 Cyrene deal substantially more personal damage over time. Less impactful in short content where fights end before max stacks are reached.

E6 – Maximum Investment

E6 grants 100% Action Advance to all allies on the first Ultimate and provides action advance bonuses on subsequent Ode applications. A transformative effect at very high investment. Practically, E2 is the ceiling most players should target.

Cyrene Rotation Guide – How to Play Her

Cyrene’s rotation has a clear objective before any fight: reach 24 Recollection, fire the first Ultimate to activate all ally Ultimates, then maintain the True DMG Zone with the Skill while letting subsequent Ultimates fire at 12 Recollection intervals.

Before the Fight

Use Cyrene’s Technique to deploy the Zone immediately and give all allies the 50% SPD buff. This pre-deploys the 20% DEF reduction at battle start, meaning it is active before any enemy action on turn 1.

Ramping Recollection

On Cyrene’s first few turns, alternate between Skill (3 Recollection) and Basic ATK (1 Recollection) to build toward 24. Every ally action also fires 1 Recollection from Future consumption. In a full Remembrance team with active Memosprites, Future triggers happen constantly — Cyrene’s first Ultimate arrives as early as turn 3 or 4 in fast-cycling teams. Keep the Zone active with Skill use so the True DMG bonus is running continuously while Recollection builds.

First Ultimate – The Burst Window

When Recollection hits 24, fire the Ultimate immediately. All ally Ultimates activate simultaneously. Demiurge spawns and immediately uses Minuet of Blooms and Plumes to apply Odes. Use Demiurge’s Ode in this order based on your team: apply to the primary DPS (Castorice or Phainon) first to maximise the opening burst window while all the ally Ultimates and buffs are simultaneously active.

For Phainon teams specifically: do not let Phainon use his transformation Ultimate until after this sequence. The combined Cyrene Ultimate + Ode to Phainon + Cerydra’s Coup de Main window is when Phainon should transform. Coordinate this carefully.

Maintaining the Loop

After the first Ultimate, Recollection costs drop to 12. Use Skill every other turn to maintain the True DMG Zone. Refill Recollection through Enhanced Basic ATK (3 Recollection), Skill (3 Recollection), and Future consumption from allies. Fire the subsequent Ultimate whenever Recollection hits 12 to send Demiurge on another Ode application and refresh Zone buffs. The loop is self-sustaining in Remembrance teams.

Should You Pull Cyrene in HSR 4.3?

Yes — if you own multiple Chrysos Heirs, Cyrene is arguably the highest-value support investment in the current meta. Her Ode system provides character-specific buffs that are substantially more powerful than generic team buffs, and her first Ultimate’s mass ally activation is one of the most explosive opening moves in the game. The combination of 20% DEF reduction, 12% True DMG Zone, 180 SPD team DMG boost, and tailored Odes creates a support package that no other character in HSR currently replicates.

The honest caveat: Cyrene’s value scales directly with how many Chrysos Heirs you own. With three Chrysos Heirs (Castorice, Phainon, Evernight), she is transformative. With one (Castorice only), she is still very strong. With zero Chrysos Heirs, she provides only generic buffs — and Robin, Tribbie, or Ruan Mei likely serve your team better. The value proposition is heavily tied to account composition.

One practical note: without the signature Light Cone or Long May Rainbows, reaching 180 SPD purely from substat rolls requires near-perfect SPD investment. E0S0 Cyrene is functional in full Remembrance teams but may not consistently hit 180 SPD. Consider pulling the signature LC or Memory’s Curtain to S5 before investing heavily in relics.

For teams to pair with Cyrene, see our guides for Castorice, Phainon, Evernight, Hyacine, Aglaea, and Dan Heng • Permansor Terrae. For alternative supports to compare, see our guides for Tribbie, Robin, and Sunday.
