Cyrene's arrival as HSR's premier Ice Remembrance support on November 5, 2025 isn't just another character release—it's a complete paradigm shift. This SS-tier powerhouse transforms endgame content through her unique Memosprite mechanics, delivering 15-20% faster Memory of Chaos clears and opening entirely new strategic possibilities in Apocalyptic Shadow.
Cyrene Overview: Role and Strengths in HSR 3.7 Meta
Here's what makes Cyrene special: she's not competing with existing supports—she's creating her own category entirely. At E0, she earns that coveted SS rating for endgame modes, and honestly? The numbers back it up.
Her base stats at Level 80 tell a story of balanced design: 1397 HP, 446 ATK, 582 DEF, and 101 SPD. Nothing groundbreaking there, but it's her Recollection generation that matters. Basic ATK gives +1, Skill and Enhanced Basic provide +3 each, plus +1 per ally Future consumption. Simple math, complex implications.
Character Kit Analysis
The Memosprite Demiurge—that's Cyrene's signature summon—syncs its HP at 100% of Cyrene's Max HP. What's fascinating is it operates outside normal action order with SPD 0, meaning it won't mess with your rotation timing. Both characters gain +24% Max HP (nice survivability boost), while the Memosprite's Skill deals Ice DMG equal to 30% Max HP to all enemies.
Her Ultimate demands 24 Recollection initially, dropping to 12 when she enters Ripples state. That's... actually manageable with proper team building.
Cyrene's Skill creates a 2-turn Zone—think of it as battlefield control—providing +12% original DMG as True DMG per ally damage instance. True DMG, folks. That bypasses all the annoying DEF scaling we've been dealing with in recent Memory of Chaos rotations.
Now here's where it gets spicy: Causality in Trichotomy passive. You need 180 SPD minimum to unlock +20% team DMG and +2% Ice RES PEN per excess SPD up to 60. At 240 SPD, you're looking at +120% RES PEN maximum. That's... actually insane against Ice-resistant enemies.
Critical thresholds you need to memorize: 180+ SPD (unlocks Causality—non-negotiable), 200+ SPD (optimal performance sweet spot), 4000+ HP (minimum viable Memosprite damage), 6000+ HP (premium threshold where things get fun), 50% CRIT Rate (for consistent performance).

Meta Position vs Other DPS
Let's be real about this comparison. Cyrene demolishes traditional Ice supports like Pela in Remembrance-focused compositions. Sure, Pela's -40% DEF shred looks impressive on paper, but Cyrene enables True DMG scaling and Ultimate battery effects that prove superior against those annoying high-DEF Memory of Chaos bosses we've been struggling with.
Her 5-star resource investment yields 30-40% team damage increases. Even F2P builds achieve 85-90% of premium performance, which is... honestly better than I expected when I first saw her kit.
Understanding Memosprite Buff Mechanics
This is where Cyrene gets really interesting. Her Memosprite doesn't just provide generic buffs—it delivers specialized Ode effects tailored to each Chrysos Heir. Think of it as character-specific steroids.
Buff Activation Conditions
Ode to Life and Death (Castorice): Allows Newbud overflow to 200%—yes, you read that right—adding +0.48% DMG multiplier per 1% consumed against ≤2 enemies. The math gets ridiculous fast.
Ode to Worldbearing (Phainon): Grants 6 Coreflames plus Eternal Ignition on Transform. Excess beyond 12 provides +6% Khaslana CRIT DMG up to 36%, +8% CRIT Rate, and refreshes +4 Scourge turns. That's a lot of moving parts, but the payoff is substantial.
Ode to Time (Evernight): Provides +9% Dream DMG, +1 Memoria post-Skill/Ultimate, and +6% of Evernight's CRIT DMG to Skill boost. Clean, straightforward, effective.
Mono-Remembrance teams generate +6 starting Recollection versus +2-3 in mixed compositions. That difference matters more than you'd think for Ultimate frequency. E2 Cyrene adds +12 starting Recollection, enabling immediate Ultimate access for burst phases—though we'll discuss whether that investment makes sense later.
Top 5 Cyrene Teams for Memory of Chaos
Premium Whale Compositions
Team 1: Cyrene + Castorice + Evernight + Hyacine
Peak Remembrance synergy right here. Castorice serves as primary DPS using those overflow mechanics I mentioned, while Evernight provides CRIT DMG buffs and Memoria generation. The team generates 6 Recollection points per cycle, enabling rapid Ultimate cycling that feels almost unfair against current content.
Team 2: Cyrene + Phainon + Cerydra + Dan Heng PT
Phainon hypercarry setup that leverages Eternal Ignition for sustained True DMG output. Cerydra amplifies damage through talent stacking (her kit is honestly underrated), while Dan Heng PT provides shields and follow-up attacks. Solid, reliable, expensive.
Team 3: Cyrene + Anaxa + Cerydra + Hyacine
Anaxa's Military Merit stacking synergizes beautifully with Cyrene's action advance mechanics. The team restores 1 SP, advances action 100%, and adds 3 Skill bonuses duplicated to 4 Skills with 32 total bonuses via Cerydra's Talent. Numbers get big. Fast.
Mid-Spender Options
Team 4: Cyrene + Mydei + Tribbie + Hyacine
Mydei benefits from Ode to Strife, removing CC effects and providing +100% CRIT DMG in Godslayer state or +100% action advance otherwise. Flexible, powerful, doesn't require perfect artifacts to function.
Team 5: Cyrene + Aglaea + Sunday + Hyacine
Aglaea receives Ode to Romance, maximizing Garmentmaker SPD with +70 Energy post-attack, +72% DMG, and 18% DEF ignore until Supreme Stance ends. Sunday's inclusion here isn't accidental—his SP management makes this rotation smooth.

F2P Friendly Builds
F2P Core: Cyrene + Trailblazer (Ice) + Dan Heng PT + Flex DPS
This accessible composition requires 2 Chrysos Heirs for battery effects—that's your minimum viable product. Trailblazer provides +8% Demiurge Max HP ATK and +36% CRIT Rate via Ode to Genesis.
F2P builds achieve 85-90% of premium performance using Memory's Curtain Never Falls (S5) and mixed relic sets. That's... actually impressive for a 4-star light cone option.
Best Cyrene Teams for Apocalyptic Shadow
Apocalyptic Shadow's Instigation of the Locusts phase (November 10 - December 22, 2025) features specific enemy weaknesses that play directly into Cyrene's strengths. Sometimes the stars align perfectly.
Boss-Specific Strategies
Sky-Shrouding Stardevourer Swarm: Features Physical/Ice/Quantum/Imaginary weaknesses—basically a love letter to Remembrance teams. Optimal composition uses Castorice (DPS), Evernight (Support), Cyrene (Support), and Hyacine (Sustain) to exploit Quantum/Ice weaknesses for AoE summon elimination.
Phantylia: Requires careful Lotus management, which honestly feels like a puzzle mini-game. Defeat Abundance Lotus for Break Effect buffs and Destruction Lotus for All-Type DMG bonuses before Eternal Condemnation activation. Cyrene's Memosprite Skill gains +15% damage under Ruinous Embers buff—free damage is good damage.
Brand of Anamnesis axiom provides +5%/10%/20% enemy DMG taken with 2/3/4 Remembrance characters respectively. Cyrene teams naturally achieve 4 Remembrance units, maximizing this bonus for substantial damage amplification. The math works out beautifully.
Optimal Light Cones and Relic Builds
Signature vs Alternative Light Cones
This Love, Forever (5-star Signature): Provides 18% SPD, applies Blank (+10% enemy DMG taken) and Verse (+16% ally CRIT DMG) effects. At S1, stacked effects yield 70% vulnerability and 76% CRIT DMG bonuses. Premium performance, premium price.
Memory's Curtain Never Falls (4-star Alternative): At S5, grants +12% SPD and +16% ally DMG for 3 turns post-Skill, achieving 86% of signature performance. For F2P players, this is your best friend.
Performance comparison breakdown: Signature S1 (100% baseline), Long May Rainbows S5 (96% efficiency—surprisingly close), Memory's Curtain S5 (86% efficiency, F2P accessible), Victory In a Blink S5 (88% efficiency).
Relic Set Combinations
Primary Build: 2pc Sacerdos' Relived Ordeal + 2pc Messenger Traversing Hackerspace
Prioritizes SPD scaling essential for Causality passive activation. Pair with Sprightly Vonwacq ornaments for 40% battle-start action advance. This setup eliminates most ramp-up issues.
Alternative: 4pc World-Remaking Deliverer
Provides +8% CRIT Rate, +24% Max HP conditional, and +15% ally DMG when Memosprite is active. Solid option if you're struggling with CRIT Rate substats.
Stat Priority: Main Stats (Body HP%/CRIT DMG, Feet SPD, Sphere HP%/Ice DMG, Rope HP%), Substats (SPD ★★★, HP% ★★★, CRIT DMG ★★, CRIT Rate ★★).
SPD and HP% are non-negotiable. Everything else is optimization.
Team Rotation and Combat Strategies
Skill Usage Order
Standard Rotation: Pre-battle Technique for 30-second freeze and +50% ally speed → Combat Entry Skill deployment for Zone activation (+3 Recollection) → Resource Building through ally Future consumption to reach 24 Recollection → Ultimate Burst to summon Memosprite → Sustained Phase with Enhanced Basic AoE.
Cyrene operates SP-neutral post-Ultimate but requires careful pre-Ultimate management. Think of it as front-loading your investment for sustained returns.
Mono-Remembrance teams provide superior resource generation with +6 starting Recollection versus mixed compositions. The difference feels substantial in practice.
Timing Memosprite Activations
Memosprite targeting priority follows DPS > Support > Sustain hierarchy. Target primary damage dealers first for maximum impact, then enhance team buffers, finally applying defensive benefits to healers. Simple logic, maximum efficiency.
Cyrene vs Meta DPS Comparison
Cyrene enables 15-20% faster Memory of Chaos clears through True DMG bypass and Ultimate battery mechanics. Her support scaling provides 30-40% team damage increases, particularly effective against those annoying high-DEF Stage 12 bosses that have been giving everyone trouble.
vs. Pela: Superior in Remembrance niches with True DMG scaling vs. -40% DEF shred. Different tools for different jobs.
vs. Traditional DPS: She enables hypercarry potential rather than competing directly. Think enabler, not replacement.
E0S1 outperforms E1S0 in most scenarios—prioritize Light Cone acquisition over Eidolon advancement. E2 represents the critical breakthrough point, providing +12 starting Recollection and +6% True DMG multiplier per unique ally buff up to 24%. That's where whales should stop, honestly.
Common Mistakes and Troubleshooting
Team Building Errors
Insufficient SPD Priority: Always prioritize SPD Boots and substats to reach 180+ threshold. Use Sprightly Vonwacq ornaments to offset slow ramp-up periods. This isn't optional.
Mixed Team Compositions: Using non-Remembrance units reduces Recollection generation significantly. Maintain 2+ Chrysos Heirs minimum for efficient battery effects. I've seen too many players ignore this and wonder why their rotations feel clunky.
Improper Memosprite Targeting: Follow DPS > Support > Sustain priority, focusing on units that benefit most from specific Ode effects. Don't waste your Memosprite on random targets.
Combat Execution Issues
Slow Ultimate Ramp-up: Build 180+ SPD and use mono-Remembrance teams for +6 starting Recollection versus +2-3 in mixed compositions. E2 adds +12 starting Recollection for immediate access, but that's whale territory.
Low Memosprite Damage: Prioritize HP scaling with 4000+ baseline, 6000+ optimal. Use HP% main stats on Body/Sphere/Rope for maximum Memosprite Skill effectiveness. The damage scales harder than you'd expect.
Advanced Tips and Future-Proofing
Future Memory of Chaos phases will likely emphasize summon mechanics and True DMG scaling—the writing's on the wall. Cyrene's kit synergizes with anticipated Remembrance character releases, ensuring sustained relevance through multiple patches.
E2 Investment Justification: The +12 starting Recollection eliminates ramp-up issues while +6% True DMG multiplier per unique ally buff (maximum 24%) provides substantial scaling. This represents the optimal stopping point for most players. Beyond E2? Diminishing returns kick in hard.
Investment recommendation: Acquire Cyrene if owning 2+ Heirs, otherwise prioritize universal supports. Her niche specialization provides exceptional value within Remembrance teams while offering limited utility outside this archetype. Know what you're buying.
FAQ
How do Memosprite buffs work with different Chrysos Heirs?
Each Chrysos Heir receives unique Ode effects when targeted by Cyrene's Memosprite Skill. Castorice gains overflow mechanics for 200% Newbud consumption, Phainon receives 6 Coreflames plus Eternal Ignition, and Evernight gets +9% Dream DMG with Memoria generation. It's character-specific optimization at its finest.
What's the minimum SPD requirement for Cyrene to be effective?
180 SPD minimum to unlock Causality in Trichotomy—this provides +20% team DMG and +2% Ice RES PEN per excess SPD up to 60. Optimal performance occurs at 200+ SPD, while 240 SPD maximizes RES PEN at +120%. Don't skimp on SPD boots.
Which team composition works best for F2P players?
F2P players should use Cyrene + Trailblazer (Ice) + Dan Heng PT + flexible DPS slot. This requires 2 Chrysos Heirs minimum for battery effects. Use Memory's Curtain Never Falls S5 Light Cone targeting 180+ SPD, 4000+ HP, and 30%+ CRIT Rate. Achievable with patience and smart resource management.
How does Cyrene compare to other Ice supports like Pela?
Cyrene outperforms Pela in Remembrance-focused teams through True DMG scaling and Ultimate battery effects. While Pela provides -40% DEF shred, Cyrene enables 15-20% faster clears against high-DEF Memory of Chaos bosses. Different niches, but Cyrene's feels more future-proof.
What are the most common mistakes when building Cyrene teams?
Major mistakes include insufficient SPD priority (missing 180+ threshold), using mixed team compositions instead of mono-Remembrance for optimal Recollection generation, and improper Memosprite targeting. Always prioritize SPD, maintain 2+ Chrysos Heirs, and target DPS units first. Simple rules, big impact.
Is E2 Cyrene worth the investment for endgame content?
E2 represents the optimal investment point, providing +12 starting Recollection for immediate Ultimate access and +6% True DMG multiplier per unique ally buff up to 24%. This eliminates ramp-up issues and provides substantial damage scaling for Memory of Chaos and Apocalyptic Shadow optimization. Beyond E2? Save your money for the next character.
