Character Breakdown: What These Two Actually Bring to the Table
Castorice's Kit (And Why It's Broken for Cyrene)
Castorice rocks the 5-star Quantum Remembrance role with solid base stats: 1629 HP, 523 ATK, 485 DEF, and 95 SPD at Level 80. Her Enhanced Skill is where things get spicy—it burns 40% of your party's HP for a devastating joint attack dealing 30%+50% Max HP AoE Quantum damage.
But here's the kicker: her Ultimate summons Netherwing (SPD 165, HP equals 100% max Newbud) with a ridiculous +100% action advance, plus it creates Territory that shreds enemy All-Type RES by 20%.
Her Talent? Pure genius. She gains Newbud from party HP loss, stacking +20% DMG up to 3 times for 3 turns. In Cyrene teams specifically, Newbud overflow enables exponential damage scaling through +0.24% DMG multiplier per 1% overflow—and it jumps to +0.48% against two or fewer enemies. That's not a typo.
Tribbie's Abilities (Solid, But Not Spectacular)
Tribbie operates as a 5-star Quantum Harmony unit: 1047 HP, 523 ATK, 727 DEF, 96 SPD at Level 80. Her Skill grants Numinosity, providing 24% All-Type RES PEN for 3 turns—straightforward and reliable. Ultimate deals 30% Max HP AoE damage while creating Zone, which increases enemy damage taken by 30% plus 12% Max HP Additional damage per hit for 2 turns.
Her Talent triggers Follow-up attacks (18% Max HP AoE) after each ally Ultimate. Traces provide +72% DMG post-Follow-up for 3 stacks lasting 3 turns. It's good. Just not game-changing.
Quick note for resource management: HSR top up Oneiric Shard through BitTopup keeps your pulls flowing with competitive pricing and instant delivery.
Support Role Reality Check
Here's where Castorice gets absolutely wild. She receives Cyrene's memosprite buff enabling Newbud overflow to 200%—consumed on Netherwing summon for +0.24% DMG multiplier per 1% overflow. This creates specialized damage amplification that's literally tailored for HP-consumption mechanics.
Tribbie gets an alternative buff ignoring 12% enemy DEF plus +1 extra Zone damage instance on Follow-ups. The mathematical scaling? Castorice's exponential growth crushes Tribbie's linear progression every time.
What Cyrene Teams Actually Need (And Who Delivers)
Cyrene's Optimal Requirements
Cyrene debuts as a 5-star Ice Remembrance unit: 1397 HP, 446 ATK, 582 DEF, 101 SPD at Level 80. She needs 2+ Chrysos Heirs for optimal Recollection generation, starting with 6 points when 3 other Heirs are present. Her Ultimate requires 24 Recollection points and summons a memosprite that shares HP and buffs.
Her A6 Trace is crucial—requires ≥180 SPD for +20% ally DMG plus Ice RES PEN (2% per excess SPD up to 60%). Miss this threshold and you're leaving damage on the table.
Support Synergy Breakdown
Castorice synergizes through HP-drain mechanics, building Newbud via her Contained Dark Tide trace, converting healing to 100% Newbud (capped at 12% max per ally). This creates a feedback loop where HP consumption directly fuels damage amplification. Brilliant design.
Tribbie leverages Cyrene's Ultimate battery for Follow-up resets and Zone uptime. She provides consistent AoE pressure through 18% Max HP Follow-ups but lacks that exponential scaling potential that makes Castorice shine.
Team Composition Reality
Premium teams run Castorice, Evernight, Cyrene, Hyacine—maximizing Newbud generation with sustain. F2P alternatives? Castorice, Trailblazer (Ice Remembrance E1+), Pela, Lynx while maintaining that 2+ Remembrance requirement.
The Math That Matters: Damage Calculations
Castorice's Numbers (They're Insane)
Cyrene enables 200% overflow versus the base 100%, translating to +48% DMG multiplier in scenarios with two or fewer enemies. Combined with Territory's 20% RES reduction, total amplification reaches +68%. Newbud caps at 34,000 base, doubling to 68,000 with overflow. E2 adds another +30% Newbud on Enhanced Skill.
Tribbie's Mathematics (Solid But Limited)
Numinosity provides 24% All-Type RES PEN for 3 turns. Zone adds 30% damage taken plus 12% Max HP Additional damage per hit for 2 turns. In Cyrene teams, DEF ignore (12%) and extra instances create effective 36% penetration.
Follow-up damage totals 18% Max HP × 3 per rotation plus 12% Additional per hit. Testing shows 90% Max HP extra damage versus Castorice's 300% on Netherwing vanish. The gap is massive.
DPS Analysis (The Verdict)
Castorice achieves +68% total amplification versus Tribbie's +36% in 3-enemy scenarios. Real testing demonstrates 15% faster Pure Fiction clears due to concentrated burst potential. Breakpoint analysis consistently favors Castorice in scenarios with two or fewer enemies, while Tribbie edges ahead in dense AoE situations.
Rotation Guides That Actually Work
Castorice-Cyrene Rotation (Advanced)
Start with Technique for instant Netherwing → Enhanced Skill for joint AoE while consuming HP → Cyrene Ultimate for overflow buff → Netherwing Breath escalation. Target 180 SPD on Cyrene for +20% team DMG, maintain Castorice below 95 SPD for 100% CRIT Rate at 7000+ HP.
Advanced players can achieve 24 Recollection points in 2 turns with proper HP drain sequencing. It takes practice, but the payoff is enormous.
Tribbie-Cyrene Rotation (Straightforward)
Cyrene Skill for True DMG → Tribbie Skill for RES PEN → ally actions build Recollection → Cyrene Ultimate refills team Ultimates → Tribbie Ultimate creates Zone. Optimize for 2-turn cycles using 160+ SPD, target HP 5000+ for +28% CRIT DMG bonus.
Critical Timing Breakpoints
Here's what matters: Cyrene needs 180+ SPD to activate team buffs, 200 SPD provides maximum RES PEN (60% Ice). Castorice below 95 SPD maintains relic passive. Tribbie needs 160+ SPD with ERR 124% for 2-turn Ultimate cycles.
For seamless progression, instant Stellar Jade recharge through BitTopup provides reliable services with competitive rates and immediate processing.
Equipment Optimization (What Actually Works)
Castorice's Best Build
Best-in-slot Make Farewells More Beautiful provides HP scaling, DEF ignore, and turn advance. Relics: Poet of Mourning Collapse 4-piece for Quantum DMG plus CRIT Rate when SPD drops below 95. Ornaments: Bone Collection's Serene Demesne for CRIT DMG at 5000+ HP.
Stats priority: Body CRIT DMG, Feet HP%, Sphere HP%/Quantum DMG, Rope HP%. Targets: HP 7000+, CRIT Rate 100%, CRIT DMG +150%. These numbers aren't suggestions—they're requirements.
Tribbie's Support Build
Signature If Time Were a Flower offers CRIT DMG, energy post-Follow-up, and team CRIT DMG sharing. Relics: Eagle of Twilight Line 4-piece for action advance post-Ultimate. Alternative: 2-piece Messenger + 2-piece Sacerdos for +12% SPD.
Stats: SPD (Feet), HP% (Body/Sphere), ERR (Rope). Priorities: SPD > HP% > CRIT Rate > ERR. Simple and effective.
Cyrene Optimization
Cyrene optimization uses This Love, Forever (+18% SPD, +70% enemy DMG taken/+76% ally CRIT DMG). F2P Memory's Curtain Never Falls provides 86% signature performance. Target 180+ SPD for team DMG trace, 4000+ HP for memosprite scaling.

Investment Analysis (What It'll Cost You)
Character Investment Requirements
Full optimization requires 3.3M Credits plus 200+ enemy drops for Level 80. Ascension needs 15 Ethereal Omen/Echoing Wail/Eternal Lament, 65 Darkveil Moonlight, 308K Credits. Traces demand 15 Bija of Consciousness, 41 Ethereal Omen, 72 Seedling of Manas.
E2 Castorice provides exceptional value through +30% Newbud generation, creating 60% effective scaling in Cyrene rotations. That's a game-changer.
Return on Investment Reality
Castorice E2 yields 30-40% team DPS increase versus Tribbie E1's 20-25% boost. F2P viability: Castorice E0S0 achieves 85-90% optimal performance. Long-term value favors Castorice due to specialized Cyrene synergy that won't be powercrept easily.
F2P vs Whale Considerations
F2P players benefit from accessible performance ceiling through skill-based optimization. Whale investment unlocks E6 potential: +20% Quantum RES PEN, weakness ignore, +3 bounces. Tribbie offers linear scaling without dramatic breakpoints—safer but less exciting.
3.7 Meta Context (What's Coming)
Current Meta Position
Version 3.7 emphasizes Remembrance synergies through Brand of Anamnesis buffs (+20% enemy DMG taken with 4 Remembrance characters). This heavily favors Castorice teams incorporating multiple Remembrance units. Chrysos Heirs faction bonuses benefit both characters through starting Recollection increases.
Current endgame design favors burst damage over sustained pressure, perfectly aligning with Castorice's concentrated windows.
Future Outlook
Upcoming Remembrance releases will likely expand overflow mechanics, providing extended Castorice value. Tribbie's universal RES PEN ensures continued viability but may face competition from superior Harmony alternatives down the line.
Long-term Viability Assessment
Castorice's specialized Cyrene synergy creates a future-resistant team core through unique overflow mechanics that can't be easily replicated. Tribbie's broad applicability ensures utility but may transition from optimal to serviceable with power creep.
