Cyrene's arrival in HSR 3.7 shakes up the meta as a 5-star Ice Remembrance support with her unique memosprite companion. Here's everything you need to know about builds, teams, and why she might just become your new favorite support character.
Meet Cyrene: Your New Ice Support Powerhouse
So here's the deal with Cyrene – she's not your typical support character. This 5-star Ice Remembrance unit comes with a memosprite buddy called Demiurge that basically acts like having an extra team member. At level 80, you're looking at 1397 HP, 446 ATK, 582 DEF, and 101 SPD. Nothing groundbreaking stat-wise, but that's not where her magic happens.
What makes her interesting? She ditches the traditional Ultimate energy system for something called Recollection points – you need 24 of them instead of the usual energy bar. You'll get these through Basic ATK (1 point), Enhanced Basic ATK (3 points), Skill (3 points), and when your allies consume Future stacks.
Demiurge syncs at 100% of Cyrene's HP and operates outside the normal action order. Plus, both characters get a nice +24% Max HP bonus just for existing together. The memosprite also has this neat trick where it reduces continuous effects by one turn after using abilities – basically built-in cleansing.

Light Cone Deep Dive: What Actually Works
This Love Forever – The Premium Choice
Cyrene's signature weapon is honestly pretty impressive. At level 80, you get 1270 HP, 476 ATK, 463 DEF, and +18% SPD. But here's where it gets spicy – it creates two different buffs called Blank and Verse.
Blank makes enemies take +10% more damage, while Verse gives your allies +16% CRIT DMG. When both are active? The potency jumps by 60%, reaching 70% enemy vulnerability and 76% ally CRIT DMG. At S5, you're looking at +30% SPD, +18% Blank, +28% Verse, and an +80% combined boost.
Fair warning though – ascension materials include Fear-Stomped Flesh x20 and Bija of Consciousness x4, plus 385,000 Credits. The banner runs from November 4 to December 16, 2025, so plan accordingly.
F2P Options That Don't Suck
Memory's Curtain Never Falls from the Herta Store is your best bet at S5. It gives +12% SPD and +16% ally damage for 3 turns after using Skill, achieving about 86% of the signature's performance. Not bad for free.
Victory In a Blink offers +24% CRIT DMG and +16% ally damage when your memosprite targets allies. Long May Rainbows focuses on SPD bonuses and enemy vulnerability, actually reaching 96% signature efficiency in some scenarios.
Here's my tier breakdown:
S-Tier: This Love, Forever (obviously)
A-Tier: Long May Rainbows (96% efficiency), Memory's Curtain S5 (86%)
B-Tier: Victory In a Blink S5 (88%), Sweat Now Cry Less (basic but functional)
Relic Strategy: Speed is Life
The Stats That Actually Matter
Body piece should be CRIT DMG or HP% – I lean toward HP% because of memosprite scaling. Boots are non-negotiable SPD. Sphere can be HP% or Ice DMG%. Rope works with HP% or Energy Regeneration Rate.
Your sub-stat hunting priority: SPD > CRIT Rate/CRIT DMG > HP%. Don't compromise on this order.
The magic number is 180+ SPD. Hit this threshold and you unlock Causality in Trichotomy: +20% team damage plus +2% Ice RES PEN per excess speed point (capped at 60%). Most optimized builds aim for 200+ SPD. You'll also want 4000+ HP minimum, though 6000+ HP is where things get really interesting for memosprite damage.
Relic Set Combinations That Work
Best-in-Slot is 4pc Deliverer's Hood. You get +8% CRIT Rate, conditional +24% Max HP, and +15% ally damage when your memosprite's active. Pair it with Amphoreus ornament for +8% CRIT Rate and +8% ally SPD when memosprite's doing its thing.
Alternatives include 2pc Messenger + 2pc Sacerdos for +12% total SPD. Sprightly Vonwacq gives +40% action advance at battle start – pretty solid for getting things rolling. Bone Collection offers +12% Max HP and +28% CRIT DMG when HP exceeds 5000.
Skill Priority: Where to Spend Your Resources
Development Order That Makes Sense
Priority goes: Memosprite Skill > Skill > Talent/Ultimate > Basic ATK. Getting that Memosprite Skill to level 10 maximizes ally buff scaling and those crucial Chrysos Heir interactions.
Your Skill enhances Zone True DMG from 12% to 24% of original damage per ally instance – and this ignores enemy defenses completely. That's huge against tanky bosses.
Talent improves the +20% team damage while on-field and Future stack generation. Ultimate affects memosprite duration and ally activation efficiency. Basic ATK and Memosprite Talent? Lowest priority, honestly.
Material Shopping List
Complete development requires: Ethereal Omen x56, Echoing Wail x71, Eternal Lament x73, Tracks of Destiny x8. For ascension: Travel Encounters x21, Adventure Log x8, Traveler's Guide x287, Sea Siren's Torn Fin x65.
Additional materials: Bīja of Consciousness x18, Seedling of Manas x69, Flower of Ālaya x139, Daythunder Anamnesis x12. Total credit cost: 3,888,100. Yeah, it's expensive.
Team Building: Who Plays Nice with Cyrene
DPS Partnerships That Click
Castorice is probably her best friend. The Newbud overflow mechanics scale to 200% effectiveness with +0.48% Talent damage per stack. Evernight combinations give +18% damage and +1 Memoria generation.
Mydei teams are interesting – you get CC removal and +200% CRIT DMG auto-skill activation, though you'll need solid HP sustain. Anaxa compositions provide +1 SP, immediate action advance, and +60% ATK/40% Skill damage for Erudition characters.
Phainon synergies offer +6 Coreflames battle-long, 72% CRIT DMG, and +16% CRIT Rate (just watch that HP consumption). Aglaea partnerships give one-time +70 Energy, +72% damage, and 36% DEF ignore.
Support Combinations
For sustain, Hyacine brings +2 Ode stacks, +24 Energy, and +72% healing. Lingsha offers universal healing plus break support. Huohuo provides energy regeneration with team buffs. Luocha gives consistent healing without eating up action costs.
Harmony options include Sunday (+100% action advance, CRIT buffs), Tribbie (damage instances + DEF ignore), Robin (team damage amplification), and Trailblazer (Ice) for F2P Remembrance synergy plus 72% CRIT Rate ode.
When you're building these teams, BitTopup ensures efficient top up Honkai Star Rail Oneiric Shards with competitive pricing and 24/7 support. Because nobody wants to wait when they're ready to pull.
Team Strategy Examples
Mono-Remembrance gives +6 starting Recollection from three Remembrance allies versus +2-3 from mixed teams. For F2P players, try: Cyrene + Trailblazer (Ice) + Dan Heng • Permansor Terrae + any DPS. Hybrid compositions work well with 2 Chrysos Heirs + 1 universal support + 1 sustain.
Eidolon Investment: What's Worth Your Money
E1-E6 Breakdown
E1 gives +6 Recollection post-Ode and +12 bounces on Memosprite Skill – basically doubles your Ultimate frequency. E2 provides +12 starting Recollection and +6% True DMG per unique ally buff (24% maximum). This is your highest value stopping point.
E4 adds +6% Bounce DMG per Minuet stack (24 maximum). E6 delivers +100% team action advance on first Ultimate, +20% enemy DEF shred, and +24% ally advance on subsequent buffs.
My investment priority: E2 > E1 > E6 > E4. Generally, E0S1 outperforms E1S0 because of those immediate SPD benefits. E2 enables immediate Ultimate activation and permanent damage scaling.
Value Assessment
F2P achieves 85-90% performance at E0S0, which is honestly pretty good. E2S1 reaches 100% potential with significant endgame advantages. E2 provides the highest performance increase per Eidolon for 0-cycle clear potential.
F2P vs Premium: The Reality Check
Budget Configuration
Memory's Curtain S5 from Herta Store, 2pc Messenger + 2pc Sacerdos for +12% SPD, Sprightly Vonwacq ornaments. Target stats: 180+ SPD, 4000+ HP, 30%+ CRIT Rate, 140% Energy Regeneration Rate. Material investment takes about 2-3 months of dedicated farming.
Premium Optimization
This Love Forever S1-5, 4pc Deliverer's Hood, Amphoreus ornaments. Advanced stats: 200+ SPD, 6000+ HP, 50%+ CRIT Rate. E2S1 investment provides immediate Ultimate activation, +24% True DMG scaling, and permanent Zone effects.
The Performance Gap
F2P achieves 85-90% of premium performance in standard content. Premium builds provide 15-20% faster clear times through enhanced action economy. But here's the thing – endgame viability remains strong for F2P in Memory of Chaos and Pure Fiction.
How She Stacks Against Other Ice Supports
Pela Comparison
Pela brings universal -40% DEF reduction, immediate debuff application, 4-star investment costs, and universal team flexibility. Cyrene specializes in Chrysos Heir teams, True DMG scaling, requires ramp-up time, costs 5-star resources, and focuses on Remembrance niche.
Lynx Analysis
Lynx offers healing + cleansing + modest amplification with 4-star investment and universal sustain application. Cyrene provides pure support + memosprite mechanics, burst amplification + Ultimate battery, requires premium resources, and excels in specialized meta compositions.
They serve distinct roles without overlapping functionality. Cyrene excels in Remembrance compositions and True DMG scenarios against high-defense enemies.
Endgame Performance: Where She Shines
Memory of Chaos
True DMG scaling bypasses enemy DEF completely, providing consistent amplification against high-HP bosses. E2 enables 0-cycle potential with proper coordination. Statistical analysis shows 15-20% faster clear times versus traditional supports through Ultimate battery effects and +20% team damage passive.
Optimal rotation: Technique (30-second Dimension) → Skill (Zone activation) → ally Future consumption → Ultimate coordination with burst windows.
Pure Fiction
AoE Zone effects and memosprite damage work beautifully across multiple waves. Enhanced Basic ATK provides AoE coverage while generating Recollection. Permanent Zone effects post-Ultimate maintain True DMG scaling throughout extended engagements.
Damage Calculations
Multiple damage vectors include memosprite HP scaling, 24% True DMG per ally instance, and team buffs ranging from +40% universal to specialized Chrysos Heir bonuses. E2 adds +24% True DMG through unique interactions. Signature LC contributes 76% ally CRIT DMG + 70% enemy vulnerability when stacked.
Combined effects? You're looking at 30-40% team damage increase.
Common Mistakes and Pro Tips
Build Errors to Avoid
Don't neglect the 180 SPD breakpoint – you lose passive activation and team damage bonuses. Stop prioritizing personal damage over support functionality; it reduces team effectiveness. Insufficient HP scaling limits memosprite damage correlation. Choosing damage sets over SPD optimization hurts action economy.
Rotation Optimization
Start with Technique initialization → Skill for Zone + 3 Recollection → ally Future consumption → Ultimate at 24 Recollection + ally readiness → Enhanced Basic for AoE + sustained momentum. Your memosprite should alternate between ally buffs (Chrysos Heirs) and enemy attacks for signature LC optimization.
Advanced Strategies
SPD tuning at 200+ maximizes RES PEN and action frequency. HP scaling at 5000+ unlocks ornament bonuses. E1 bounce optimization gives +12 instances per Memosprite Skill. For signature LC management, alternate targets for dual buff activation (70% vulnerability + 76% CRIT DMG).
