Cyrene Substats Guide: HP% vs DEF% Priority for F2P

Cyrene Planar Ornament Mechanics

Cyrene's memosprite has HP equal to 100% of Cyrene's Max HP—every HP point translates to combat power. The memosprite executes a Skill dealing 30% of its Max HP as Ice DMG, while Waltz of Flowers and Arrows delivers 50% of memosprite Max HP as Ice DMG to all enemies.

Level 80 Cyrene provides 1397 base HP, 446 ATK, 582 DEF, 101 SPD. These stats reveal her design: moderate defense with emphasis on HP scaling for offensive memosprite output, not personal survivability.

Four viable planar sets exist:

• Bone Collection's Serene Demesne: +12% Max HP, +28% CRIT DMG (both wearer and memosprite) at 5000+ HP
• Fleet of the Ageless: +12% Max HP, +8% ATK to allies at 120 SPD
• Amphoreus The Eternal Land: +8% CRIT Rate for memosprites, +8% SPD to allies
• Sprightly Vonwacq: +5% Energy Regen, 40% action advance at 120+ SPD

Optimal Slot Distribution

Planar Sphere: HP% main stat (Ice DMG% alternative for direct damage focus) Link Rope: HP% main stat (Energy Regen Rate for 140 energy Ultimate struggles)

A Cyrene with 6879 HP, 189 SPD, 38% CRIT Rate, 182% CRIT DMG demonstrates achievable F2P benchmarks—memosprite deals 2063 Ice DMG per Skill and 3439 AoE Ice DMG through Waltz.

Cyrene Acquisition for F2P

Farm Simulated Universe World 6+ where gold ornament drop rates justify Trailblaze Power. Daily regeneration limits farming to 3-4 runs, making main stat acquisition more critical than perfect substats. Functional HP%/HP% Sphere/Rope outperforms perfectly-rolled DEF% pieces.

DEF% vs HP%: Core Comparison

Cyrene's combat contribution flows through memosprite damage, not personal survivability. Unlike traditional tanks where DEF% reduces incoming damage, Cyrene's memosprite HP converts directly to offensive Ice DMG.

HP% substats increase Cyrene's Max HP, which increases memosprite Max HP identically. One HP% roll (4.3% average) = ~60 HP on base 1397 HP Cyrene = 60 memosprite HP. This yields:

• +18 Ice DMG per Skill (30% of 60)
• +30 AoE Ice DMG through Waltz (50% of 60)

DEF% substats (5.4% average) add ~31 DEF to base 582 DEF. Against Level 95 enemies in MoC Floor 12, this creates marginal survivability improvements that don't enhance memosprite damage.

Effective HP (EHP) Calculation

EHP = HP / (1 - Damage Reduction)

For Cyrene with 4000 HP, 600 DEF vs Level 95 enemies:

• Damage Reduction = 600/(600 + 200 + 950) = 0.343
• EHP = 4000/(1 - 0.343) = 6088

Increasing DEF to 631 (DEF% substats):

• Damage Reduction = 0.360
• EHP = 4000/(1 - 0.360) = 6250 (+162 EHP)

Increasing HP to 4172 (HP% substats):

• EHP = 4172/(1 - 0.343) = 6350 (+262 EHP)

HP% provides superior EHP scaling while simultaneously boosting memosprite damage.

Diminishing Returns

DEF% experiences steeper diminishing returns due to denominator growth in damage reduction formulas. At 800 DEF vs Level 95 enemies, Damage Reduction reaches 0.410—requiring exponentially more DEF for meaningful gains.

HP% scales linearly with no diminishing returns. Each percentage point adds consistent HP regardless of current total. For Cyrene, this linear scaling extends to memosprite damage, making HP% mathematically superior for both survivability and offense.

Memory of Chaos Floor 12 Analysis

MoC Floor 12 (Dec 8, 2025 - Jan 19, 2025) features enemy configurations demanding Ice responses. Memory Turbulence grants ally summons 40% DMG boost at cycle start, plus True DMG instances (1 per summon, max 2). This directly amplifies Cyrene's memosprite damage.

A memosprite dealing 2000 base Ice DMG receives 800 additional damage from turbulence buff, plus True DMG bypassing enemy DEF.

For optimizing Stellar Jade acquisition, HSR Cipher E0 pure fiction stellar jade recharge bundle at BitTopup provides cost-effective solutions.

Damage Types and Survival

Floor 12 Node 3 enemies execute Physical, Elemental (Ice/Lightning/Quantum), and True Damage. DEF% mitigates Physical and Elemental but provides zero value against True Damage. HP% creates buffer against all damage types equally.

Critical survival checkpoints occur at 50% and 25% enemy HP where bosses execute enhanced attacks. With 40% summon DMG boost, a 5000 HP memosprite deals 2100 Ice DMG per Skill (30% × 5000 × 1.4). HP investment directly correlates to clear speed.

Why Node 3 Demands Defensive Optimization

Node 3 features highest enemy HP pools and damage output. Unlike Nodes 1-2 where offensive stats enable brute-force clears, Node 3 punishes glass cannon builds through sustained damage over 8-12 cycles.

Cyrene's memosprite must maintain field presence. A memosprite eliminated mid-rotation creates 3-4 cycle DPS loss while Cyrene regenerates 12 Recollection points (first Ultimate requires 24). HP% substats ensure memosprite survival through damage spikes.

F2P Ice Summon Roster

Trailblazer Ice Remembrance: Most accessible ice summon for F2P. Free character summons memosprite benefiting from 40% summon DMG boost. No gacha investment required.

Evernight: Premium ice summon option. Synergizes with Cyrene through shared Ice element. Castorice-Evernight-Cyrene-Hyacine maximizes summon count, though F2P substitutes with Archer and supports.

March 7th: Most accessible ice shielder. Shields absorb damage before HP depletion, multiplying Cyrene's EHP without DEF% investment. Allows full HP% substat focus.

Yanqing: High-risk ice DPS with CRIT scaling. Standard banner availability makes him realistic for F2P, though survivability issues demand careful team construction.

Summon Durability Mechanics

Summons inherit specific stats from summoners while maintaining independent HP pools. Cyrene's memosprite copies her Max HP exactly—every HP% substat roll enhances memosprite durability.

Summons take damage independently. Memosprite elimination doesn't damage Cyrene but removes her primary damage source until Ultimate reactivation. Investing in Cyrene's DEF% improves her survivability but provides zero benefit to memosprite durability. HP% investment strengthens both Cyrene and memosprite while increasing memosprite damage—triple benefit makes HP% mathematically superior.

Mathematical Breakdown: DEF% vs HP% in MoC 12-3

Baseline: 4000 HP, 600 DEF, 180 SPD vs Level 95 enemies dealing 1500 raw damage

• Damage Reduction = 0.343
• Damage taken = 985 per hit
• Survives 4.06 hits

Scenario A (+20% HP substats):

• Total HP = 4800
• Damage taken = 985 per hit (unchanged DEF)
• Survives 4.87 hits (+20% survivability)
• Memosprite HP = 4800
• Skill damage = 1440 Ice DMG (30% × 4800)
• Waltz damage = 2400 AoE Ice DMG (50% × 4800)

Scenario B (equivalent DEF% substats):

• DEF = 720
• Damage Reduction = 0.385
• Damage taken = 922 per hit
• Survives 4.34 hits (+6.9% survivability)
• Memosprite HP = 4000 (unchanged)
• Skill damage = 1200 Ice DMG (no improvement)
• Waltz damage = 2000 AoE Ice DMG (no improvement)

Breakpoint Analysis

DEF% theoretically surpasses HP% at extreme DEF values (1200+) where additional DEF% creates significant damage reduction increases. However, reaching these breakpoints requires sacrificing HP% entirely, eliminating memosprite damage scaling.

For Cyrene, no practical breakpoint exists where DEF% becomes superior. Memosprite damage—Cyrene's primary combat contribution—scales exclusively with HP. Even if DEF% provided superior personal survivability (which math disproves in realistic ranges), the offensive loss makes DEF% counterproductive.

Real Clear Data

F2P MoC Floor 12 clears using Archer-Xueyi-Trailblazer Ice-Lynx achieve 3-star clears within 10 cycles. Trailblazer Ice with 4500 HP summons memosprites dealing 1350 base Skill damage, amplified to 1890 with 40% turbulence. Over 10 cycles with 2 Skill activations per cycle = 37,800 damage from memosprite alone.

DEF-focused builds with 4000 HP complete identical content in 12-13 cycles due to reduced memosprite damage. The 2-3 cycle difference translates to missed 3-star achievements and reduced Stellar Jade rewards.

Substat Priority by Character

Cyrene hierarchy: SPD to 180-200 > HP% > flat HP > Effect RES > CRIT Rate/CRIT DMG

This reflects Cyrene's role as summon-focused support. The 180+ SPD threshold activates team-wide buffs granting +20% DMG plus +2% Ice RES PEN per excess SPD point (max 60 penetration at 210 SPD).

Alternative builds prioritize SPD > CRIT Rate/CRIT DMG > HP for personal damage emphasis. However, for F2P ice summon teams relying on Cyrene's memosprite as primary damage dealer, HP% substats after SPD threshold provide superior value.

Universal Substat Hierarchy

Ideal Cyrene substats:

• 4-5 SPD rolls reaching 189+ total SPD
• 3-4 HP% rolls adding 15-20% HP
• 1-2 flat HP rolls contributing 200-400 HP
• Remaining rolls in Effect RES or CRIT stats

This achieves 180 SPD threshold, reaches 4000+ HP baseline (5000+ with premium investment), maintains acceptable CRIT ratios.

Minimum thresholds:

• 180 SPD (non-negotiable for buff activation)
• 4000 HP (minimum memosprite viability)
• 25% CRIT Rate (baseline for occasional CRIT procs)
• 100% CRIT DMG (achievable through main stats alone)

Tank/Shielder Cases

March 7th: Sole ice character where DEF% competes with HP%. Shield strength scales with DEF, making DEF% investment enhance protective capabilities. However, even for March 7th, HP% provides superior value in summon-focused teams.

Lynx: Benefits from DEF% for enhanced healing output and survivability. Healing scales with Max HP (prefer HP% main stats), but DEF% substats improve survival during healing downtime. Mixed HP%/DEF% substats on supports provide balanced performance, while primary DPS and summon characters demand HP% focus.

Practical Substat Rolling Strategy

F2P players face strict Trailblaze Power limitations. Acceptable Cyrene pieces require:

• Correct main stat (HP% on Sphere and Rope)
• 2+ desirable substats (SPD, HP%, flat HP)
• Upgrade rolls hitting desirable substats 60%+ of time

Perfect pieces with 4 desirable substats and 80%+ favorable upgrades remain unrealistic for F2P timelines.

Stop rolling when: main stat correct, 3+ desirable substats exist, total SPD reaches 15+ or HP% reaches 12%+. Further optimization yields diminishing returns vs improving other team members. Full Cyrene set with acceptable pieces outperforms single perfect piece with empty slots.

Trailblaze Power Efficiency

Each Simulated Universe World 6 run costs 40 Trailblaze Power, yields 2-3 gold ornaments with 15% probability of Cyrene pieces (6-7 ornament sets in drop pool). Expected Cyrene piece acquisition requires 13-20 runs, consuming 520-800 Trailblaze Power. With 240 daily regeneration, obtaining full 2-piece Cyrene set demands 4-7 days dedicated farming.

Substat rolling occurs automatically during piece acquisition—can't selectively reroll without obtaining new pieces. This makes initial piece acquisition with correct main stats the primary goal, with substat optimization occurring passively through duplicate replacement over weeks.

Common Rolling Mistakes

Mistake 1: Discarding pieces with correct main stats but imperfect substats. A Cyrene Sphere with HP% main stat and SPD/HP%/DEF%/Effect RES substats remains usable despite DEF% presence. Replacing requires another HP% Sphere with superior substats—potentially weeks of farming.

Mistake 2: Prioritizing CRIT substats over HP%. While CRIT improves Cyrene's personal damage, memosprite damage scales exclusively with HP. Cyrene with 5000 HP and 20% CRIT Rate contributes more team damage than 4000 HP with 60% CRIT Rate due to memosprite scaling.

Team Composition Factors

Cyrene's optimal substats shift based on team. In teams with dedicated healers (Lynx, Luocha), Cyrene's personal survivability becomes less critical, allowing aggressive HP% stacking for max memosprite damage. Teams lacking sustain require balanced HP%/DEF% to prevent Cyrene elimination before Ultimate.

Castorice-Evernight-Cyrene-Hyacine premium composition provides abundant healing/shielding, enabling full HP% focus. F2P Archer-Xueyi-Trailblazer Ice-Lynx includes Lynx healing, similarly supporting HP% prioritization. Teams replacing Lynx with non-sustain characters demand 10-15% additional HP% investment.

Light Cone Synergies

Light cones providing HP% bonuses synergize with HP% substats through multiplicative scaling—20% HP light cone × 20% HP substats = compounding benefits. DEF% light cones favor DEF% substats, though Cyrene's memosprite damage scaling makes HP% light cones universally superior.

Energy Regen Rate light cones enable faster Ultimate cycling, reducing Recollection point accumulation pressure. Cyrene's first Ultimate requires 24 Recollection points, subsequent Ultimates need 12. Faster Ultimate access maintains memosprite uptime, indirectly improving damage without offensive stat investment.

Energy Regen and Defensive Stats

Cyrene's 140 energy Ultimate cost creates rotation timing challenges. Energy Regen Rate substats on Link Rope (alternative to HP% main stat) accelerate Ultimate charging, though sacrificing HP% main stat reduces memosprite damage. Optimal balance depends on team energy generation—teams with abundant energy batteries maintain HP% Rope, energy-starved teams consider Energy Regen alternatives.

Sprightly Vonwacq provides +5% Energy Regen with 40% action advance at 120+ SPD. This enables faster rotation cycling, potentially compensating for reduced HP% from alternative planar sets. However, Bone Collection's +28% CRIT DMG at 5000+ HP typically provides superior damage for HP-stacked builds.

Common Misconceptions

More HP is always better oversimplifies defensive optimization. While HP% provides superior value for Cyrene, other characters with DEF-scaling abilities or shields benefit more from DEF% investment. Generalizing HP% superiority across all characters creates suboptimal builds for DEF-scaling units.

Conversely, undervaluing DEF% for appropriate characters represents equally problematic thinking. Characters like March 7th with DEF-scaling shields or Gepard with DEF-based abilities gain significant value from DEF% substats. Key distinction: evaluate whether character abilities scale with HP or DEF, then prioritize corresponding substats.

DEF% Undervaluation Problem

Community perception dismisses DEF% as universally inferior to HP%, creating market inefficiencies where DEF-scaling characters receive suboptimal builds. This stems from early-game content where raw HP pools provide sufficient survivability without DEF optimization. Endgame content like MoC Floor 12 reveals DEF%'s value for appropriate characters.

For Cyrene specifically, DEF% undervaluation isn't problematic—HP% genuinely provides superior value. However, players building comprehensive rosters should recognize DEF%'s situational value for tank and shielder characters.

Flat vs Percentage Stats

Flat HP substats contribute 100-200 HP per roll, while HP% adds 4-5% per roll. On 1397 base HP Cyrene, 5% HP = 70 HP—seemingly inferior to 150 flat HP. However, HP% scales with all HP bonuses from light cones, planar sets, relic main stats, while flat HP remains static.

Cyrene with +60% HP from equipment transforms 5% HP substats into 112 HP (5% of 2235 total HP), surpassing flat HP value. This scaling difference makes percentage substats superior for characters with substantial equipment HP bonuses. Cyrene builds targeting 5000+ HP accumulate +150% HP from main stats and set bonuses, making HP% substats scale to 3.5× base value.

Step-by-Step Implementation for MoC 12-3

Phase 1: Audit current Cyrene ornaments for main stat correctness and substat quality. Verify Planar Sphere carries HP% or Ice DMG% main stat, Link Rope features HP% or Energy Regen main stat. Examine substats for SPD, HP%, flat HP, CRIT presence. Calculate total SPD to determine distance from 180 threshold.

Phase 2: Identify priority upgrade pieces based on main stat deficiencies and substat quality. Sphere with ATK% main stat requires immediate replacement regardless of substats. Rope with correct HP% main stat but zero SPD substats becomes secondary priority.

Rank by urgency:

1. Incorrect main stats
2. Correct main stats with 0-1 desirable substats
3. Correct main stats with 2+ desirable substats

Phase 3: Allocate 100% daily Trailblaze Power to Simulated Universe ornament farming until Cyrene achieves minimum viable stats: 180 SPD, 4000 HP, HP%/HP% main stats on Sphere/Rope. Focused farming typically requires 7-14 days depending on RNG. Don't split Trailblaze Power—concentrated farming accelerates progression.

Select World 6+ for optimal gold ornament drop rates. Lower worlds yield excessive blue/purple ornaments diluting useful drops. World 9 provides maximum efficiency for developed rosters, though World 6 remains accessible for most F2P accounts.

Phase 4: After achieving minimum viable stats, attempt MoC Floor 12 Node 3 to establish baseline performance. Record cycle count, memosprite survival rate, damage output per rotation. Identify failure points:

• Does memosprite die before Ultimate reactivation?
• Does insufficient damage prevent 3-star clear within cycle limits?
• Do energy generation issues delay Ultimate timing?

Iterate based on failure analysis. Memosprite survival issues demand additional HP% investment or team composition adjustments adding healers/shielders. Damage insufficiency requires optimizing CRIT substats or upgrading other team members. Energy problems necessitate Energy Regen Rope or Sprightly Vonwacq consideration.

Advanced Optimization Tips

Speed tuning coordinates Cyrene's action timing with support characters for optimal buff alignment. Cyrene's 180+ SPD activates team buffs, but excessive SPD creates turn order issues where Cyrene acts before supports apply buffs. Target 180-200 SPD for Cyrene, supports at 160-175 SPD for proper buff sequencing.

SPD-based Ice RES PEN bonus grants +2% penetration per SPD point above 180, capping at 60% penetration (210 SPD). This applies to all Ice damage including memosprite output, making SPD investment valuable beyond action frequency. However, reaching 210 SPD requires sacrificing HP% substats, creating tradeoffs between penetration bonus and raw damage scaling.

Conditional DEF% Buffs

Certain supports provide conditional DEF% buffs that multiply with base DEF and DEF% substats. These create scenarios where moderate DEF% investment gains value through multiplicative interactions. However, for Cyrene specifically, even multiplicative DEF% scaling doesn't enhance memosprite damage output, maintaining HP%'s superiority.

Players building comprehensive rosters should recognize these multiplicative opportunities for DEF-scaling characters while maintaining HP% focus for summon-based units.

Future-Proofing Cyrene Investment

Cyrene's memosprite damage scaling ensures long-term viability as HP-based mechanics remain relevant across content updates. Unlike CRIT-focused DPS requiring constant stat inflation, HP-scaling summon characters benefit from any HP% bonuses introduced through new equipment or mechanics.

Investing in HP% Cyrene builds creates transferable knowledge for future summon characters. Trailblazer Ice Remembrance already demonstrates parallel design, suggesting future ice summon characters will follow comparable scaling patterns. HP% optimization skills developed through Cyrene building apply broadly to emerging summon-focused meta compositions.

FAQ

What main stats should Cyrene's Planar Sphere and Link Rope have?

Planar Sphere requires HP% main stat for max memosprite HP scaling (Ice DMG% secondary option). Link Rope demands HP% main stat (Energy Regen alternative for 140 energy Ultimate struggles). These main stats directly increase memosprite HP, converting to Ice DMG through Skill (30% Max HP) and Waltz (50% Max HP).

Is DEF% ever better than HP% for Cyrene substats?

No. Cyrene's memosprite damage scales exclusively with HP—DEF% provides zero offensive benefit while offering inferior survivability vs HP% in practical stat ranges. Math shows HP% delivers superior EHP gains while simultaneously boosting memosprite damage. Avoid DEF% on Cyrene in favor of SPD, HP%, flat HP, or Effect RES.

What SPD threshold should Cyrene reach?

Cyrene must achieve 180 SPD minimum to activate team-wide buffs granting +20% DMG and +2% Ice RES PEN per excess SPD point (capping at 60% penetration at 210 SPD). Optimal range spans 180-200 SPD, balancing buff activation with turn order coordination. Exceeding 200 SPD requires excessive substat investment that could otherwise boost HP%.

Which planar ornament set works best for F2P Cyrene builds?

Bone Collection's Serene Demesne provides optimal value with +12% Max HP and +28% CRIT DMG at 5000+ HP threshold. F2P players unable to reach 5000 HP should use Fleet of the Ageless for +12% Max HP and team-wide +8% ATK at 120+ SPD. Both sets prioritize HP scaling enhancing memosprite damage.

How much HP should Cyrene have for MoC Floor 12 clears?

Minimum viable HP totals 4000+ for basic MoC Floor 12 participation. Premium builds target 5000+ HP to unlock Bone Collection's CRIT DMG bonus and maximize memosprite damage scaling. The 6879 HP example represents aspirational goals requiring extensive substat optimization over weeks.

Can F2P teams clear MoC Floor 12 with Cyrene?

Yes. F2P composition Archer-Xueyi-Trailblazer Ice-Lynx successfully clears MoC Floor 12 first half within 10-12 cycles when properly built. Cyrene's memosprite benefits from 40% summon DMG boost in current Memory Turbulence, enabling competitive damage without premium characters. Focus on achieving 180 SPD and 4000+ HP thresholds for minimum viable performance.
