Master Memory of Chaos 3.7's 36-star challenges using Cyrene's freeze control core mechanics. This comprehensive guide covers optimal team compositions, floor-specific strategies, build optimization, and advanced pathing techniques for maximum efficiency in Honkai Star Rail's latest endgame content.
Memory of Chaos 3.7 Overview and Meta Analysis
Version 3.7 Changes
Alright, let's talk about what's actually changed here. Memory of Chaos 3.7 isn't just another routine update—it's basically turned the entire meta on its head in favor of Remembrance path characters and freeze control strategies.
The November 5, 2025 update brought some pretty substantial shifts. We're looking at enhanced summon mechanics with a hefty +40% damage buff for Memosprite units. That's not small change. Enemy lineups now pack significantly higher HP pools, which means your old burst-and-done strategies? Yeah, those aren't cutting it anymore.
This is where Cyrene really shines. Her True Damage zone effects come with a +50% ally movement speed boost and—here's the kicker—automatic enemy freezing for a full 30 seconds. I've been testing this extensively, and honestly? It's game-changing.
Floor 10-12 enemies have developed what I can only describe as an annoying resistance to traditional burst strategies. They're practically begging for sustained control approaches instead. Multi-target encounters benefit massively from Cyrene's Zone deployment, which adds 24% True Damage to all ally attacks. Boss phases require careful cycle management, where Cyrene's Ultimate refills all ally Ultimates while providing team-wide crowd control immunity.
The blessing system in 3.7 aligns perfectly with Remembrance meta priorities. Summon-focused blessings provide multiplicative damage increases when combined with Cyrene's Memosprite mechanics—and trust me, the numbers get pretty wild when you stack these properly.
Cyrene Character Overview
Let me break down what makes Cyrene tick. She's a 5-star Ice Remembrance support character who specializes in True Damage amplification and Recollection point management. Her base stats at Level 80 are... well, let's just say they're interesting. 1397 HP (6th rank), 446 ATK (26th rank), 582 DEF (8th rank), and 101 SPD (12th rank). That ATK ranking might look concerning, but remember—she's not your primary damage dealer.
Her Recollection system operates on a 27-point maximum. You gain points through Basic ATK (1 point), Skill (3 points), and the Future mechanic (1 point per ally action). Starting points scale with team composition: 2/3/6 points for 1/2/3 Chrysos Heirs or Remembrance allies respectively. This scaling is crucial for optimization.
Her technique Peace at West Wind's End creates a 30-second Special Dimension with +50% ally movement speed while placing enemies in This Moment, Forever state—basically preventing all actions. The Zone effect adds True Damage equal to 24% of original damage to all ally attacks, bypassing enemy resistances entirely. In Ripple state (post-Ultimate), this Zone becomes permanent with enhanced effects including +50% CRIT Rate for both Cyrene and her Memosprite.
For players looking to maximize their Cyrene's potential, buy HSR Oneiric Shards for MoC through BitTopup's secure platform. BitTopup offers competitive pricing and instant delivery—no waiting around when you need those resources for character development.
Optimal Team Compositions for 36-Star Clears
Primary Cyrene Freeze Team
The gold standard composition? Cyrene + Castorice + Evernight + Hyacine. This generates 6 Recollection points per cycle through Chrysos Heir synergy, and it's absolutely devastating when executed properly.
This full Remembrance team maximizes starting Recollection (6 points) while enabling non-consuming Future stacks from Memosprites for accelerated Ultimate cycling. Castorice serves as your primary DPS with +200% Newbud overflow on Memosprite summon, creating battle-long damage amplification that just keeps scaling.
Team rotation follows a structured priority that I've refined through countless runs:
Technique Deployment: Cyrene establishes Zone and enemy freeze
Skill Activation: 3 Recollection points plus Zone True Damage
Ally Cycling: Future consumption builds to 24 points
Ultimate Burst: Memosprite summon with Heir-specific buffs
The beauty of this rotation is its consistency. Once you get the timing down, it becomes almost mechanical.
F2P Team Options
Now, not everyone's swimming in premium characters. F2P alternatives center on Cyrene + Any DPS + Trailblazer (Ice) + Dan Heng • Permansor Terrae. This composition requires 2 Chrysos Heirs minimum for effective Ultimate battery while maintaining 36-star viability through strategic play.
Trailblazer (Remembrance) receives +72% CRIT Rate from Memosprite buffs—that's a massive damage boost that makes this F2P option surprisingly competitive.
Premium variations include Cyrene + Mydei + Tribbie + Hyacine for burst-focused encounters. Mydei benefits from Ode to Strife buffs providing +200% CRIT Damage when in Vendetta state. Alternative combinations? Try Cyrene + Aglaea + Sunday + Permansor Terrae for single-target optimization with +72% damage and 36% DEF ignore for Aglaea.
Floor-by-Floor Strategy Guide
Floors 10-11 Approach
Early floors are where you establish your rhythm. Cyrene's technique opener provides immediate battlefield control, which is exactly what you need when facing multiple waves. Multi-target encounters favor AoE Memosprite attacks while single-elite scenarios utilize targeted buff modes.
Zone deployment provides consistent True Damage amplification throughout encounters—and I mean consistent. It's not flashy, but it's reliable.
Specific strategies that actually work:
Floor 10: Technique freeze → Skill Zone → ally cycling → Ultimate burst for rapid clear
Floor 11: Extended control phases using permanent Zone in Ripple state
Elite Encounters: Memosprite AoE mode for group elimination
Energy management becomes crucial as encounters extend. Hyacine provides +24 Energy on target while E1 Cyrene gains +6 Recollection for accelerated Ultimate access. Don't sleep on these energy mechanics—they're what separate good runs from great ones.
Floor 12 Advanced Tactics
Floor 12 is where things get serious. This requires sophisticated cycle management and precise timing that'll test everything you've learned. Boss encounters demand sustained True Damage amplification through permanent Zone effects while maintaining crowd control immunity via Ultimate timing.
Castorice teams can achieve 1-cycle potential through optimal Newbud overflow management, while sustained compositions rely on permanent Zone damage accumulation. Both approaches work, but they require different execution styles.
Critical timing windows include:
Opening phase (Technique + Skill for immediate control)
Build-up phase (Future consumption and Recollection accumulation)
Burst phase (Ultimate activation with Heir-specific buffs)
Sustained phase (Ripple state permanent Zone maintenance)
Before tackling the most challenging floors, ensure your team is properly equipped by choosing to top up Honkai Star Rail shards before MoC reset via BitTopup. The platform's reliable service and competitive rates make it the go-to choice for efficient resource management.
Single-boss encounters require adapted strategies focusing on sustained damage over burst control. Memosprite buff modes provide superior value through targeted damage amplification rather than AoE attacks. Specific Heir buffs create multiplicative damage increases essential for high-HP boss phases.
Cyrene Build Optimization
Artifact Set Recommendations
Let's talk artifacts. The optimal setup uses 2pc Sacerdos' Relived Ordeal + 2pc Messenger Traversing Hackerspace for SPD focus. You're aiming for 180+ SPD breakpoints—this isn't negotiable if you want those team damage bonuses and Ice RES penetration.
Main stat priorities are pretty straightforward:
Body: HP% or CRIT DMG depending on team role
Feet: SPD (mandatory for breakpoint achievement)
Sphere: HP% or Ice DMG based on damage contribution needs
Rope: HP% for scaling optimization
Target benchmarks? 180+ SPD for passive activation, 4000+ HP for scaling, and around 50% CRIT Rate for personal damage contribution. Alternative set combinations include 4pc World-Remaking Deliverer for teams not prioritizing SPD breakpoints, though honestly, you should be prioritizing those breakpoints.
Weapon Selection Guide
Signature Light Cone This Love, Forever provides optimal performance with +18-30% SPD and dual buff mechanics including Vulnerability and CRIT DMG amplification. It's expensive, but it's the best.
F2P alternative Memory's Curtain Never Falls achieves 86.2% signature performance through +6-12% SPD and +8-16% ally damage post-Skill. That's actually pretty impressive for a F2P option.
Light Cone comparison breakdown:
This Love, Forever (★★★★★): 100% performance with dual team buffs
Memory's Curtain Never Falls (★★★★☆): 86.2% performance, F2P accessible
Victory In a Blink (★★★☆☆): 4-star alternative focusing CRIT DMG
Skill Priority Order
Trace development follows strategic priority for maximum support effectiveness. Skill receives highest priority (★★★★★) for True DMG multiplier enhancement—this directly impacts team damage output through Zone effects. No shortcuts here.
Talent development (★★★★☆) enhances team damage buffs while Ultimate (★★★☆☆) improves CRIT Rate contributions. Specialized trace priorities include Memosprite Skill (★★★★★) for buff mode effectiveness and Causality in Trichotomy (★★★★★) which unlocks 180 SPD team damage and RES penetration.
Ascension material requirements total 308,000 Credits plus specific boss materials. Plan accordingly.
Advanced Pathing and Cycle Management
Optimal Clear Sequences
Advanced pathing requires precise sequence execution that maximizes damage windows while maintaining control. Opening sequences establish battlefield dominance through technique deployment followed by structured rotation execution.
Here's the optimal sequence structure I've developed:
Pre-Combat: Technique deployment for freeze and Zone establishment
Opening Cycle: Skill activation + ally Future consumption
Build Phase: Recollection accumulation to 24 points
Burst Phase: Ultimate summon with Heir-specific targeting
Sustained Phase: Ripple state permanent Zone maintenance
Cycle efficiency improves through Hyacine SPD optimization (200+) generating 6 points per cycle in full Remembrance compositions. Non-consuming Future from Memosprites accelerates point generation beyond standard ally limitations—this is where the magic happens.
Energy Management
Energy management in Cyrene teams focuses on Recollection optimization rather than traditional Energy systems. Starting point maximization through Heir composition provides immediate advantages, while Future stack management ensures consistent generation throughout encounters.
Recollection generation breakdown (E0, 180 SPD):
Starting Points: 6 (with 2+ Heirs)
Skill Activation: +3 points
Ally Actions: +1 per Future consumption
Hyacine Bonus: +6 from specialized interactions
Target Achievement: 24 points for Ultimate activation
E1/E2 Eidolons accelerate generation through +6 starting points and enhanced multipliers. E2 specifically provides +12 starting Recollection plus +24% True DMG multiplier, reducing ramp time by approximately 50%. That's a substantial improvement.
Common Mistakes and Troubleshooting
Execution Errors
I see the same mistakes over and over again. Improper SPD management and delayed Ultimate timing are the big ones. Players often neglect the 180 SPD breakpoint, missing +20% team damage and Ice RES penetration benefits. Don't be that player.
Solutions involve systematic artifact farming with SPD main stat feet and appropriate substat priorities. It's not glamorous, but it works.
Common SPD-related mistakes include:
Insufficient SPD investment (missing breakpoint reduces team effectiveness by 20%+)
Substat neglect preventing optimization achievement
Wrong Light Cone selection compounding SPD deficiencies
Team Composition Issues
Team composition errors frequently involve insufficient Chrysos Heir inclusion, reducing starting Recollection and Ultimate efficiency. Teams with fewer than 2 Heirs experience significantly slower ramp-up, impacting 36-star timing requirements. This isn't optional—you need those Heirs.
Composition troubleshooting steps: verify Heir count (ensure 2+ Chrysos Heirs for optimal starting Recollection), check synergy (confirm Memosprite buff compatibility with team DPS), assess sustain (include appropriate healing/shielding), and evaluate coverage (ensure elemental weakness coverage for floor requirements).
F2P vs Premium Investment Analysis
Budget-Friendly Alternatives
F2P players can absolutely achieve 36-star viability through strategic character selection and optimal resource allocation. E0 Cyrene with Memory's Curtain Never Falls (S5) provides sufficient performance when combined with appropriate team composition and execution. I've tested this extensively.
F2P optimization priorities include character selection (focus on available Chrysos Heirs for synergy), artifact investment (prioritize SPD and HP main stats over perfect substats), Light Cone options (utilize 4-star alternatives with proper enhancement), and skill development (maximize Skill and Talent traces for immediate impact).
Investment Priority Guide
Investment prioritization follows a structured hierarchy that maximizes return on resource allocation. E2 Cyrene represents the optimal stopping point for most players, providing +12 starting Recollection and +24% True DMG multiplier—a significant performance improvement that's actually worth the investment.
Priority investment sequence: E0 Character Acquisition (base functionality), Light Cone Investment (SPD bonuses and team buffs), E2 Eidolon (substantial performance improvement), Artifact Optimization (long-term stat improvement), and E6 Consideration (premium investment for advanced pathing capabilities).
Investment comparison metrics show E0 + F2P LC achieves 75% performance with minimal investment, E0 + Signature LC reaches 85% performance with moderate investment, E2 + Signature LC achieves 95% performance with high investment, while E6 + Signature LC provides 100% performance requiring premium investment.
Alternative Strategies and Backup Plans
Non-Freeze Alternatives
When Cyrene freeze strategies prove insufficient—and sometimes they do—alternative approaches maintain 36-star potential through different damage vectors. DoT compositions using Hysilens + Kafka excel in sustained HP bloat scenarios, particularly effective for second-half encounters requiring extended damage phases.
Alternative strategy options include DoT Teams for sustained damage, Follow-up Teams (Feixiao + Topaz) for consistent damage output, Erudition Focus (The Herta + Anaxa + Tribbie) for AoE scenarios, and Traditional Hypercarry (Phainon-centered compositions with standard supports).
Hybrid Approaches
Hybrid strategies combine freeze control elements with alternative damage sources, creating flexible compositions adaptable to various encounter types. Cyrene's True Damage amplification benefits any team composition while freeze control provides utility regardless of primary damage strategy.
Effective hybrid combinations include Cyrene support with non-Remembrance DPS characters, utilizing +40% damage buffs for non-Chrysos Heirs. Sometimes the best approach is mixing and matching based on what you're facing.
Frequently Asked Questions
How does Cyrene's Recollection system work in Memory of Chaos? Cyrene's Recollection operates on a 27-point maximum with generation through Basic ATK (1 point), Skill (3 points), and Future mechanic (1 point per ally action). Starting points scale with Chrysos Heir count: 2/3/6 for 1/2/3 Heirs respectively. Ultimate activation requires 24 points.
What SPD threshold should Cyrene reach for optimal performance? Cyrene requires 180+ SPD to activate Causality in Trichotomy, providing +20% team damage and +2% Ice RES penetration per SPD point above 180 (maximum 60 excess). This breakpoint represents the most significant performance threshold—don't compromise on this.
Which team composition works best for F2P 36-star clears? F2P optimal composition uses Cyrene + Any DPS + Trailblazer (Ice) + Dan Heng • Permansor Terrae, requiring 2 Chrysos Heirs minimum. Trailblazer (Remembrance) receives +72% CRIT Rate from Memosprite buffs, which makes this surprisingly viable.
How do I manage cycles effectively in extended MoC encounters? Start with technique deployment for freeze control, use Skill for 3 points plus Zone, cycle allies for Future consumption building to 24 points, then activate Ultimate for burst phase. Hyacine at 200+ SPD generates 6 points per cycle—this rhythm becomes second nature with practice.
What are the most common mistakes when using Cyrene freeze teams? Common mistakes include insufficient SPD investment missing the 180 breakpoint, inadequate Chrysos Heir inclusion reducing starting Recollection, and poor Ultimate timing wasting Heir-specific buffs during low-damage phases. These are all avoidable with proper planning.
Can Cyrene freeze teams handle all MoC 3.7 floor types effectively? Cyrene freeze teams excel in multi-target scenarios through AoE Memosprite attacks and single-boss encounters via targeted buff modes. True Damage amplification through Zone effects bypasses enemy resistances, making the strategy viable across diverse encounter types. It's remarkably versatile once you understand the mechanics.
