Honkai Star Rail (HSR) Cyrene Build, Kit and Teams

Cyrene stands as a 5-star Remembrance character within Honkai Star Rail’s roster, representing the most eagerly awaited addition from the Amphoreus region. Her combat mechanics deliver distinctive enhancements to various Chrysos Heirs while simultaneously functioning as a versatile universal support unit. However, Cyrene’s intricate ability system presents significant complexity, creating substantial build challenges without expert direction. For commanders preparing to acquire Cyrene, this comprehensive HSR Cyrene build, ability breakdown, and squad formation guide delivers optimal performance strategies.

Cyrene officially launched on November 5, 2025, confirmed for Honkai Star Rail version 3.7 banners throughout the complete update cycle. She remains the exclusive new 5-star character introduction for the 3.7 version period.

Begin accumulating your Stellar Jades immediately if Cyrene features in your HSR acquisition plans. Should your Stellar Jade reserves run low, secure the most current Honkai Star Rail redemption codes for additional resources.

While Cyrene represents one of Honkai Star Rail’s most anticipated characters, her ability framework contains notable design challenges. Primarily, she demonstrates extreme reliance on activating her Ultimate ability, with energy regeneration presenting substantial obstacles. She demands 24 Recollection points, obtainable through multiple acquisition methods. Interestingly, she only needs 12 points for subsequent Ultimate activations, but her initial usage mandates the full 24-point requirement. This design creates combat scenarios where every engagement becomes a struggle to achieve her Ultimate threshold initially, since without this capability, she provides minimal combat contribution.

Once Cyrene activates her Ultimate, however, she transforms into a formidable battlefield asset. Her Ultimate automatically enables all allied team members’ Ultimate abilities simultaneously. Additionally, her Talent bestows unique enhancements to each Chrysos Heir, making her valuable across nearly all Amphoreus-themed squad configurations. She also empowers the entire team to deliver consistent True Damage with every offensive action.

Should you consider acquiring Cyrene? I cannot recommend pulling for Cyrene unless you’re prepared for substantial resource commitment. For the majority of players, Cyrene fails to deliver exceptional value to existing team compositions. Crucially, Cyrene performs poorly for free-to-play commanders, so if you identify with this player category, definitely bypass her banner.

Regarding Cyrene’s Signature Light Cone versus her initial Eidolon advancement, the decision proves remarkably straightforward. You should consistently prioritize her Signature Light Cone acquisition. Why this preference? Her exclusive Light Cone grants enhanced movement speed, elevates Critical Damage for all allies, and causes enemies to suffer additional incoming damage.

By comparison, her E1 enables increased Recollection point generation when deploying her Memosprite ability targeting her Memosprite entity, while simultaneously boosting its damage output. However, the fundamental problem with Cyrene’s kit involves reaching her Ultimate activation threshold initially. This core issue receives mitigation primarily through her Signature Light Cone, which amplifies her Speed attribute significantly.

Constructing an effective Cyrene build presents considerable complexity, and without proper guidance, mistakes become inevitable. The subsequent content outlines the optimal Cyrene configuration within Honkai Star Rail. Following these build specifications precisely will transform Cyrene into a significant advantage for your team compositions.

For commanders preferring additional build flexibility, we’ve included comprehensive alternatives below. Consult the following segments to discover expanded options for Cyrene’s Relic sets, Planetary Ornaments, stat distributions, and alternative Light Cone selections.

Advanced Optimization Tip: Focus on Energy Regeneration Rate substats to accelerate Ultimate availability. Pairing Cyrene with energy-generating supports can dramatically improve her performance consistency across various combat scenarios.

Common Mistake Avoidance: Many players undervalue Speed attributes, which critically impact her Recollection generation capabilities. Ensure your Cyrene reaches at least 134 Speed to maximize turn frequency and Ultimate uptime.

Skill Mechanics

Bloom, Elysium of Beyond: Instantly generates 3 Recollection points while establishing a specialized combat Zone that persists for 2 full turns. This duration counter decreases specifically at the beginning of Cyrene’s action cycle. The Zone’s primary function converts all allied damage instances into dual-strike attacks, adding supplementary True Damage equal to 24% of the initial damage value. Strategic consideration: the Zone immediately dissipates if Cyrene becomes incapacitated, making her survival crucial for maintaining this damage amplification field.

Ultimate Combinations

• Verse Vow: Summons the memosprite companion and grants it immediate action priority with an extra turn. This ability simultaneously triggers all allied Ultimate abilities regardless of their current energy levels. Cyrene then enters the empowered Ripples of Past Reverie state, transforming her Basic Attack into the enhanced To Love and Tomorrow variant while restricting her to this attack mode exclusively. Provides substantial critical rate enhancement of 50% for both Cyrene and her memosprite. Crucially, this ability redeploys the Skill’s Zone effect with unlimited duration. Limited to single activation per combat encounter. The memosprite’s durability scales directly from Cyrene’s maximum health pool at 100% equivalence.
• Reunion at First Sight: Grants the memosprite an additional immediate action turn, enabling rapid skill chaining and battlefield control.

Talent Optimization

• Hearts Gather as One: Activates at combat initiation or following any Cyrene action, applying the Future status to all allied characters and their respective memosprites regardless of current conditions. When allies possessing Future execute actions, they consume this buff to transfer 1 Recollection point to Cyrene. Ultimate activation requires 24 accumulated Recollection points under normal circumstances, which simultaneously clears all debilitating effects from Cyrene. During the enhanced Ripples of Past Reverie state, the Ultimate cost reduces to 12 points. Recollection capacity can exceed the maximum threshold, reaching up to 27 stored points. Additionally, Cyrene provides a persistent 20% damage amplification to all allied units while she remains active on the battlefield.

Recollection Point Management

Mastering Recollection point accumulation is fundamental to Cyrene’s effectiveness. The Future mechanic triggers after every allied action, making team composition with frequent activations particularly synergistic. Characters with multi-hit abilities or rapid turn cycles significantly accelerate Recollection generation. Advanced tactic: coordinate ally actions to maximize Future consumption before Cyrene’s turn to ensure Ultimate availability when most needed.

Zone Deployment Timing

The combat Zone represents Cyrene’s primary damage amplification tool. Optimal deployment occurs immediately before your team’s major damage-dealing phases. Since the Zone disappears when Cyrene falls, position her safely and consider pairing with defensive supports. The Zone’s true damage component bypasses all enemy damage reduction and resistance mechanics, making it exceptionally valuable against heavily armored opponents.

Team Composition Synergy

Cyrene excels in teams featuring characters with high-frequency damage instances. Each individual damage tick – whether from damage-over-time effects, multi-hit abilities, or rapid basic attacks – triggers the additional true damage. This makes her particularly devastating when combined with area-of-effect specialists or characters possessing attack-enhancing capabilities. For comprehensive team building strategies, consult our Class Selection Guide to identify optimal partnerships.

Rotation Patterns

Initiate combat with Technique application when possible to gain movement advantage and automatic Zone deployment. Build Recollection points through coordinated ally actions until reaching the 24-point threshold. Activate Ultimate during critical damage windows to maximize team output. During enhanced state, focus on building to the reduced 12-point requirement for subsequent Ultimate activations. The memosprite should alternate between damage dealing and buff application based on current battle requirements.

Common Mistakes

Avoid deploying Ultimate without proper setup – the enhanced state limits flexibility. Don’t waste the memosprite’s extra turns; plan its actions strategically. Positioning errors that get Cyrene eliminated waste the Zone investment entirely. Understanding when to use each memosprite skill is crucial; the buff provides 40% damage increase to non-Chrysos Heir allies, while the damage skill scales with memosprite health.

Advanced Techniques

Technique:

• Peace at West Wind’s End: Creates a specialized dimensional field surrounding the character with 30-second duration. Enemies within this area enter the This Moment, Forever state. Provides substantial 50% movement speed enhancement to allies within the dimensional influence. Automatically deploys the Skill’s Zone effect upon combat initiation during the technique’s active period. Important restriction: only one dimensional effect from allied sources can coexist simultaneously.

Memosprite Skill Applications

• Minuet of Blooms and Plumes: Delivers Ice-element area damage to all enemy targets calculated as 60% of the memosprite’s maximum health pool.
• This Ode, to All Lives: Applies a significant combat enhancement to a single designated ally. When targeting Chrysos Heir characters, provides unique specialized effects. For non-Chrysos Heir targets, substantially increases damage output by 40% for 2 full turns. This buff effect extends to include all active memosprites on the battlefield.

• Ode to Genesis (RMC): Effective for the entire battle. Targeting Trailblazer (Remembrance) boosts their attack power by 16% of the memosprite’s maximum HP while elevating critical hit rate by 72% of the companion’s CRIT Rate. Mem receives identical stat improvements. After Trailblazer executes Enhanced Basic ATK, the memosprite immediately gains bonus action turn and autonomously activates “Minuet of Blooms and Plumes.” If primary target gets eliminated beforehand, ability retargets to newly emerging hostile units.
• Ode to Romance (Aglaea): One-time effect. Applying to Aglaea grants “Romantic” status while instantly maximizing Garmentmaker’s SPD enhancement stacks. Following attack by Aglaea or Garmentmaker, consumes romantic buff to restore 70 Energy points. Damage output for both units increases by 72% with 36% defense penetration against targets, persisting until Aglaea exits Supreme Stance.
• Ode to Passage (Tribbie): Effective for the entire battle. Enables Tribbie to bypass 12% of enemy defenses. When triggering Follow-up ATK with Zone additional damage, delivers one extra damage instance.
• Ode to Strife (Mydei): One-time effect. Removes all crowd control debuffs affecting Mydei. If currently in Vendetta state, automatically unleashes “Godslayer Be God” without charge consumption, granting 200% critical damage multiplier for that strike. If primary target defeated, retargets to new arrivals. Outside Vendetta, advances Mydei’s action gauge by 100%.
• Ode to Life and Death (Castorice): Effective for the entire battle. Allows Newbud accumulation beyond normal limits up to 200% capacity. Summoning Netherwing consumes excess Newbud, enhancing damage multiplier by 0.24% per overflow percentage consumed during “Wings Sweep the Ruins” activation. With two or fewer enemies present during summoning, damage multiplier gains additional 0.48% boost.
• Ode to Reason (Anaxa): One-time effect. Restores one skill point for allies while granting Anaxa immediate action. Increases skill damage instances by three for one turn duration. Next Basic ATK or Skill usage grants “True Knowledge”: All Erudition Path characters gain 60% attack boost and 40% skill damage increase until Anaxa’s subsequent turn begins.
• Ode to Sky (Hyacine): When Cyrene’s Memosprite uses Memosprite Skill, applies two “Ode to Sky” stacks to Hyacine. Direct application regenerates 24 Energy. While Hyacine possesses Ode to Sky during healing actions, enhances Little Ica’s Memosprite Skill healing output by 72% of current heal value. Using Skill or Ultimate consumes one stack.
• Ode to Trickery (Cipher): Effective for the entire battle. Increases Cipher’s damage output by 36% while reducing Patron’s defense by 20% and other enemies’ defense by 12%.
• Ode to Worldbearing (Phainon): Effective for the entire battle. Application grants Phainon six Coreflames plus Eternal Ignition during transformation. When Coreflame exceeds twelve during transformation, each excess point increases Khaslana’s CRIT DMG by 12% (maximum 72%). Eternal Ignition provides 16% critical rate boost. After extra turns expire, transformation persists while refreshing all bonus turns and adding four Scourge points. Khaslana consumes 15% current HP at extra turn start. Post-attack, deals five additional damage instances, each inflicting fire damage equal to 10% of Khaslana’s ATK to random foe.
• Ode to Ocean (Hysilens): One-time effect. Grants “Flowing Warmth” status. After attacking, consumes buff to restore 60 Energy. Increases Hysilens’ damage by 120% for battle duration. Basic ATK/Skill attacks make existing DoT effects on targets immediately deal 60%/80% of original damage.
• Ode to Law (Cerydra): Effective for the entire battle. Increases CRIT DMG by 30% for character holding Military Merit. After Coup de Main concludes, Cerydra instantly gains one Charge point.
• Ode to Time (Evernight): Effective for the entire battle. Boosts damage from “Dream, Dissolving, as Dew” by 18%. Using Skill/Ultimate grants one additional Memoria point. Skill’s CRIT DMG enhancement gains extra 12% of Evernight’s CRIT DMG.
• Ode to Earth (Dan Heng Permansor Terrae): When Cyrene’s memosprite uses Memosprite Skill, grants Ode to Earth status. Souldragon’s next three attacks deal additional damage matching Bondmate’s type at 80% of shield effect value. With Ode to Earth active, Bondmate deals 24% increased damage. Direct application advances Souldragon’s action by 100%. Next action gains Ultimate enhancement effects with 150% shield value boost without consuming Ultimate charges.
• Ode to “Her Memosprite” (Cyrene’s Memosprite): After Cyrene collects Recollection from each teammate (excluding memosprite), using “Minuet of Blooms and Plumes” deals one extra ice damage instance equal to 60% of memosprite’s max HP to random enemy. After Cyrene uses Ultimate or memosprite summoning, memosprite gains one Story point. At three Story points, consumes all to gain extra turn and automatically use “Minuet of Blooms and Plumes.”

Mastering Cyrene’s memosprite system requires understanding several advanced combat principles. The Out-of-Bounds classification means your memosprite cannot be targeted by enemy attacks, making it a persistent buff source that survives throughout engagements. However, the HP synchronization means you must protect Cyrene to maintain your spectral companion’s effectiveness.

Common Mistakes to Avoid:

• Summoning memosprite too early before debuffs accumulate
• Wasting one-time Ode effects on inappropriate targets
• Ignoring the continuous effect duration reduction mechanic
• Poor timing of Ultimate usage that misses Story point accumulation
• Overlooking the HP percentage synchronization in team compositions

For optimal performance, prioritize characters whose Ode abilities complement your playstyle. The Trailblazer (Remembrance) synergy works exceptionally well for sustained damage output, while Mydei’s one-time burst can eliminate priority targets instantly. Advanced players should focus on chaining extra turns between memosprite and main damage dealers for maximum combat efficiency.

Waiting, In Every Past: Strategic Positioning

Cyrene’s memosprite operates with a unique 0 SPD value, keeping it completely absent from the standard action order. This positioning places it effectively out-of-bounds on the battlefield, creating an unconventional tactical advantage. The health synchronization between Cyrene and her memosprite ensures damage distribution remains balanced, while the 24% Max HP boost activates whenever both are fielded simultaneously. A crucial tactical consideration involves the accelerated duration reduction of continuous effects following ability usage, which demands careful timing management.

Pro Tip: Use the HP synchronization to your advantage by strategically timing healing abilities when Cyrene’s health drops low, effectively providing double recovery value.

Hello, World: Team Support Capability

The memosprite’s summoning sequence includes an immediate crowd control cleanse for all allied units, making it an invaluable emergency tool against disabling effects. This instant debuff removal can completely turn engagements where enemy control abilities threaten to overwhelm your team composition.

Battle-Long Enhancement Odes

Ode to Genesis (RMC): This permanent battle enhancement transforms Trailblazer (Remembrance) into a formidable damage dealer. The ATK boost scales directly with the memosprite’s Max HP, while CRIT Rate increases proportionally to the memosprite’s own critical statistics. The automatic follow-up attack trigger after Enhanced Basic ATK usage creates devastating combo potential, with intelligent target selection ensuring no wasted damage potential.

Ode to Passage (Tribbie): Provides consistent DEF penetration alongside amplified follow-up attack sequences. The additional damage instance from Tribbie’s Zone creates multiplicative damage scaling against clustered enemy formations.

Ode to Life and Death (Castorice): Enables Newbud overflow mechanics up to 200% capacity, with Netherwing summoning converting this excess into substantial damage multipliers. Against smaller enemy groups, the damage bonus receives significant amplification, making it exceptionally effective in boss encounters or when facing numerically disadvantaged opponents.

Ode to Trickery (Cipher): Delivers balanced offensive and defensive utility through increased personal damage output while applying targeted DEF reduction to priority targets.

One-Time Strategic Odes

Ode to Romance (Aglaea): This single-use ability instantly maximizes Garmentmaker’s SPD Boost while providing substantial energy regeneration. The damage amplification and DEF ignore persist throughout Aglaea’s Supreme Stance duration, creating extended windows of offensive dominance.

Ode to Strife (Mydei): Offers both defensive cleansing and offensive empowerment. The Vendetta state trigger enables a massively empowered Godslayer Be God without charge consumption, while the alternative action advance provides flexibility for non-Vendetta scenarios.

Ode to Reason (Anaxa): This versatile one-time effect provides immediate skill point recovery, action advancement, and temporary damage instance increases. The True Knowledge buff significantly boosts Erudition Path characters, making it ideal for specialized team compositions.

Special Condition Odes

Ode to Sky (Hyacine): Functions through stack mechanics gained from memosprite skill usage. The energy regeneration and enhanced healing for Little Ica create sustained support capabilities, with stack consumption ensuring balanced resource management.

Team Composition Optimization

Building effective teams around Cyrene requires understanding which Odes synergize with your core damage dealers. Trailblazer (Remembrance) teams benefit enormously from Ode to Genesis’s persistent buffs and automatic follow-up triggers. For Erudition-focused compositions, Ode to Reason provides exceptional value through its party-wide ATK and Skill DMG enhancements.

Common Mistake: Many players waste one-time Ode effects during low-priority phases of combat. Save these powerful abilities for crucial moments when they can maximize impact, such as boss phase transitions or when facing dangerous crowd control threats.

Advanced Combo Execution

Mastering Cyrene involves sequencing her abilities to maximize value across multiple turns. Time your memosprite summoning to counter anticipated enemy control abilities, and coordinate Ode usage with your damage dealers’ burst windows. The action advance capabilities in several Odes enable unexpected turn manipulation that can disrupt enemy action sequences.

For optimal performance, consider the Class Guide to understand how Cyrene fits within broader team archetypes and which characters benefit most from her specialized support toolkit.

The signature Light Cone “This Love, Forever” represents Cyrene’s optimal equipment choice, providing comprehensive stat enhancements that perfectly align with her combat requirements. As a 5-star Remembrance Path weapon, it delivers three distinct combat advantages: elevated critical damage for all team members, amplified damage vulnerability across enemy targets, and accelerated action speed for the equipped character. This triple-threat approach ensures Cyrene maintains consistent pressure while amplifying her teammates’ offensive capabilities.

Strategic stat prioritization should focus on achieving the 180 SPD threshold for maximum ascension ability activation. The Light Cone’s speed enhancement significantly reduces the gear investment needed to reach this critical breakpoint, allowing for more optimized substat distribution. For optimal performance, pair this equipment with characters who benefit from the team-wide critical damage amplification, particularly those with naturally high crit rate values.

The memosprite mechanics create a dynamic combat rhythm where proper ability sequencing becomes crucial for damage optimization. Each Story point accumulation represents a step toward unleashing the memosprite’s full offensive potential, with the extra turn mechanic enabling burst windows without sacrificing action economy. Mastering the timing between Ultimate usage and memosprite summoning ensures consistent Story point generation for sustained damage pressure.

The ascension abilities create powerful synergies that reward specific team compositions and stat investments. The A2 ability provides permanent buffs to teammate memosprites, while A4 dramatically accelerates Cyrene’s early combat performance through instant Recollection stacking. The A6 ability transforms speed investment into both team-wide damage amplification and personal penetration statistics, creating dual-value from a single attribute.

Optimal Cyrene gameplay revolves around meticulous rotation planning to maximize memosprite activations. Begin combat by sequencing abilities to quickly generate three Story points, prioritizing Ultimate usage when available to accelerate the process. Avoid the common mistake of summoning the memosprite prematurely before accumulating sufficient Recollection from teammates, as this wastes potential damage amplification opportunities.

Advanced players should focus on achieving 240+ SPD to capitalize fully on the Ice RES PEN mechanics, providing up to 120% additional penetration. This requires dedicated gear optimization but delivers substantial returns against high-resistance enemies. Team building should prioritize at least two Chrysos Heir or Remembrance characters to secure maximum starting Recollection points, dramatically reducing setup time.

For maximum efficiency, coordinate Cyrene’s actions with characters who can manipulate action order or provide additional turns. The memosprite’s extra turn mechanic creates windows for devastating combo sequences when properly timed with teammate buffs and enemy vulnerability phases.
