Neuvillette C1 delivers 24% DPS boost through stackable Charged Attack buffs (110-160%) and interruption resistance, enabling shielder-free teams. Tome of the Eternal Flow R1 provides 15-20% DPS gains via 16% HP, 42% Charged Attack DMG, and 8 Energy restoration every 12s. Both available Version 6.3 Phase 2 (Feb 3-24, 2026). C1 costs 75-160 pulls (12,000-25,600 Primogems), Tome R1 needs ~20 pulls (3,200 Primogems). Your choice depends on primogem reserves, weapon inventory, and team priorities.
Understanding the Investment Decision
This choice impacts damage ceiling, team flexibility, and primogem economy. C0 Neuvillette achieves ~100,000 DPS per Charged Attack cycle; C1 pushes to 125,000, Tome R1 reaches 1.2M total DPS with Furina teams.
Tome R1 costs 3,200 Primogems worst-case via Epitomized Path. C1 demands 12,000-25,600 depending on pity—a 4-8x multiplier. C1's interruption resistance frees team slots from shielders. Tome's Energy restoration enables 100-115% ER builds vs 100-125% typically required.

Key Differences: Constellation vs Weapon
C1 Venerable Institution: Grants one Past Draconic Glory stack on field entry (max 3, lasts 30s). Damage scaling: 110% (1 stack), 125% (2 stacks), 160% (3 stacks). Halves interruption instances from 10-15 Shake to manageable levels.
Tome R1: 542 base ATK, 88.2% CRIT DMG. Aeon Wave passive: 16% HP, 14% Charged Attack DMG per stack (42% total at 3 stacks, gained every 0.3s). Transferable to future Catalyst DPS.
C1 eliminates micromanagement—face-tank through enemy attacks while Sourcewater Droplets heal 16% Max HP. Tome can reassign if Neuvillette falls from meta.
Account Assessment Checklist
Pity Counters: Character soft pity at 74, hard at 90. Weapon hard pity at 80.
50/50 Status: Budget worst-case 160 pulls (25,600 Primogems) for guaranteed C1
Weapon Inventory: Lost Prayer/Skyward Atlas owners gain less from Tome R1 vs Prototype Amber users
Team Gaps: Lack Zhongli/Layla? C1's interruption resistance provides disproportionate value
Primogem Reserves: Calculate remaining 6.3 Phase 2 sources from events, Abyss, exploration
Neuvillette C1 Deep Dive
Complete C1 Breakdown
Past Draconic Glory operates on 30s timer. C1 grants instant stack on field entry—no ramp-up. Three-stack progression creates power breakpoints:
1 stack (110%): Baseline C0 with setup
2 stacks (125%): 13.6% increase, reached in 5-7s
3 stacks (160%): 28% increase over 2-stack, reached in 10-15s
Cumulative effect: 24% DPS boost in double Hydro teams.
Interruption resistance halves incoming Shake values. Neuvillette's base Charged Attack state vulnerable to 10-15 Shake hits. C1 halves to 5-7.5 Shake, effectively doubling threshold. Tanks through Hilichurls, Fatui Skirmishers, some Ruin Guard patterns without disruption.
Practical impact: C0 requires shields or precise dodging. C1 ignores most damage, channeling through attacks while Sourcewater Droplets sustain HP.
Rotation Changes
Standard C0: 18-20s rotation with 12-14s Neuvillette field time, requires defensive positioning between Charged Attacks.
C1: 16-18s rotation with continuous channeling. Instant stack allows aggressive snapshot strategies—enter during peak buffs (Kazuha Burst, Xilonen shred), immediately capitalize without ramp-up.
Multi-wave content: C0 must disengage and reposition. C1 continues channeling through spawns. Result: 15-20s faster Abyss clears, often determining 36-star vs 33-star completion.
Team Flexibility Gains
Hyperbloom: Neuvillette, Furina, Nahida, Kuki. C0 struggles with close-range Core explosions interrupting channels. C1 tanks through Core damage, maintains uptime. 1.1-1.3M total DPS.
Triple Hydro: Neuvillette, Furina, Xingqiu, Kazuha. C0 requires Zhongli for survivability. C1 enables full offensive stacking with Xingqiu's Rain Swords.
Vaporize: Neuvillette, Kazuha, Bennett, Xiangling. C1 face-tanks Pyronado knockback and enemy retaliation. 950K-1.1M DPS.
Common thread: C1 replaces defensive utility with offensive amplification, increasing team damage by 18-25% vs C0 with defensive supports.
Abyss Floor 12 Performance
Current 6.3 cycle chambers feature Consecrated Beasts, Ruin Serpent, Hydro Tulpa with aggressive patterns.
C0 + Zhongli: 90-105s per side C1 + offensive supports: 75-85s per side
15-20s advantage per chamber = 45-60s across full Floor 12, often the margin between 36-star and 33-star.
Consecrated Beast triple swipe: 36 total Shake, guaranteed interrupt for C0. C1 reduces to 18 Shake, below threshold with Droplet healing. Maintain 160% damage through enemy combos.
Tome R1 Analysis
Weapon Stats and Passive
Level 90: 542 base ATK, 88.2% CRIT DMG. Enables 200%+ CRIT DMG with Marechaussee Hunter 4pc (36% CRIT Rate from HP fluctuation) while maintaining 70-80% CRIT Rate.
Aeon Wave passive:
16% HP (32% at R5)
14% Charged Attack DMG per stack, 42% total at 3 stacks (R1)
8 Energy every 12s at max stacks
Stacks accumulate every 0.3s during channeling—reaches max within 0.9s. Synergy creates multiplicative scaling: HP amplifies base damage, Charged Attack DMG multiplies that base, Energy restoration enables Burst uptime for 30% Charged Attack buff.
Damage vs 4-Star Alternatives
Tome R1 vs Prototype Amber R5: 137% damage output. 37% differential = ~15-20s faster Abyss clears.
Tome R1 vs Widsith R5: Widsith offers burst damage during 10s buff (random 48% ATK/96% Elemental DMG/240 EM), 30s downtime. Tome averages 18-22% higher DPS over 20s rotations, gap widens past 40s.
Tome R1 vs Cashflow R1: Tome achieves 1.2M DPS vs Cashflow's 900K. Cashflow's ATK% and Normal Attack DMG misalign with Charged Attack focus. 15-20% gap.
Optimized builds: Tome R1 reaches 125,000 effective DPS per cycle vs 100,000 with Prototype Amber. Over 10-12 cycles, 25% differential accumulates substantially.
Rotation Adjustments
Energy restoration enables aggressive rotations: Skill > Team Buffs > Charged Attack, Skill, Charged Attack, Burst > Refresh > Double Charged Attack. 8 Energy per 12s ensures Burst availability with only 100-115% ER vs 120-125% required with Prototype Amber.
ER reduction reallocates 10-15% substat value to CRIT stats. Translates to ~6-8% CRIT Rate or 12-16% CRIT DMG = 4-6% multiplicative DPS increase beyond weapon stats.
0.3s stack interval synergizes with 2.5-3s Charged Attack channels. Tome reaches 3 stacks within first second, ensuring 42% Charged Attack DMG for 80-85% of damage output.
Refinement Value
R1: 16% HP, 42% Charged Attack DMG, 8 Energy
R2: 20% HP, 54% Charged Attack DMG, 9 Energy (8-10% DPS increase, costs 3,200-12,800 Primogems)
R5: 32% HP, 90% Charged Attack DMG, 12 Energy (20-25% increase over R1, costs 12,800-38,400 Primogems)
Primogem-to-performance ratio heavily favors R1. R2+ represents luxury investment—8-10% gain costs equivalent to guaranteed 5-star character. Only justified after completing meta teams.
Exception: Players with 60+ weapon pity from initial banner may find R2 accessible within 20-40 pulls (3,200-6,400 Primogems).
Direct Damage Comparison
Standardized conditions: Lv90 characters/weapons, +20 artifacts (180% CRIT DMG, 70% CRIT Rate), 4pc Marechaussee, team (Neuvillette, Furina, Kazuha, Xilonen).
C0 + Tome R1 vs C1 + Prototype Amber
C0 + Tome R1: 1.2M total DPS, 125,000 per Charged Attack. Tome's 42% Charged Attack DMG, 16% HP, 88.2% CRIT DMG with Furina/Kazuha buffs. 100% Burst uptime at 110% ER.
C1 + Prototype Amber R5: 1.05M total DPS, 110,000 per Charged Attack. C1's 24% boost partially compensates for Prototype's lack of offensive stats. Healing provides utility but no damage.
Gap: C0 + Tome R1 outperforms by 14%. Narrows in survivability scenarios. Tome costs 73-87% fewer primogems for superior damage.
C0 + Tome R1 vs C1 + Widsith
C0 + Tome R1: 1.2M DPS baseline, consistent across rotations.
C1 + Widsith R5: 1.15M during 10s buff, 900K during downtime. Averages 1.0M DPS. Random buffs create variance (1.25M peaks with Elemental DMG, 950K with ATK%).
Gap: C0 + Tome R1 delivers 20% higher average DPS, 25-30% during Widsith downtime. Consistency critical in Abyss where spawn timing misaligns with buff windows.

C1 + Lost Prayer: 57s
Total: C0 + Tome R1 (135s) vs C1 + Prototype (152s). 17s advantage provides buffer for 36-star clears.
Team Flexibility: Where C1 Shines
Hyperbloom Teams
Neuvillette, Furina, Nahida, Kuki. Dendro Cores apply 8-10 Shake at close range.
C0: Requires medium-range positioning, reduces DPS uptime 15-20%. Running Zhongli eliminates Hyperblooms, cuts team damage 25-30%.
C1: Tanks Core explosions, allows close-range positioning. Interruption threshold absorbs damage (8-10 Shake → 4-5 Shake). Effective DPS increases 18-22%.
Verdict: C1 transforms Hyperbloom from awkward to powerful. Disproportionate value for Hyperbloom-focused players.
Vaporize Teams
Neuvillette, Kazuha, Bennett, Xiangling. Pyronado creates 6-8 Shake knockback.
C0: Must time Charged Attacks between Pyronado rotations or use shields. 60-70% Vaporize uptime.
C1: Channels through Pyronado knockback. 80-90% Vaporize uptime. Instant stack ensures 110% damage during peak buffs. 1.1-1.3M DPS.
Verdict: C1 provides moderate 15-20% improvement. Less critical than Hyperbloom. Tome R1's raw damage often produces equivalent results.
Flex Teams
C0: Requires defensive flex (Zhongli, Layla) in high-pressure chambers, limits offensive potential.
C1: Eliminates mandatory defensive slot. Run Neuvillette, Furina, Kazuha, Xilonen for max damage while maintaining survivability.
Verdict: C1's flexibility scales with player skill and roster depth. Experienced players gain maximum value adapting compositions without sacrificing survivability.
Primogem Decision Tree
0-14,400 Primogems
Don't Own Neuvillette: Prioritize C0 (12,000-14,400). C0 + Prototype Amber provides 85-90% of C1 performance, 80-85% of Tome R1 damage at zero additional cost.
Own C0, 0-3,200: Save for 6.4 unless 60+ weapon pity. Insufficient for guarantee.
Own C0, 3,200-14,400: Pursue Tome R1 (3,200), save remainder. Superior primogem-to-performance ratio (15-20% DPS for 3,200 vs C1's 24% for 12,000-25,600).
14,400-28,800 Primogems
Don't Own, 14,400-28,800: Acquire C0 (12,000-14,400) + Tome R1 (3,200). Total 15,200-17,600, leaves 0-13,600 for 6.4. Establishes max practical damage ceiling (1.2M DPS).
Own C0, 14,400-28,800: Acquire Tome R1 (3,200), evaluate C1 based on remaining reserves and 6.4 priorities. If 6.4 leaks show low-priority banners, invest in C1. If high-value characters, preserve primogems.
Favorable Pity (50+ character, 60+ weapon): Pursue both if combined cost within budget. 50+ character pity = C1 costs 4,000-6,400. 60+ weapon pity = Tome costs 1,600-3,200. Combined: 5,600-9,600.
28,800+ Primogems
Don't Own, 28,800+: Acquire C0 + Tome R1 + C1 (15,200-28,800 total). C1 + Tome R1 achieves ~1.35-1.4M DPS, practical ceiling before diminishing returns. Stop after securing both—C2 (20% Hydro RES shred) offers poor efficiency vs new characters.
Own C0, 28,800+: Acquire Tome R1 + C1 (15,200-28,800), save remainder. Maximizes performance while preserving 6.4 resources.
Own C0 + Tome R1, 28,800+: Pursue C1 (12,000-25,600), save for 6.4. C1 represents final major spike before diminishing returns.
Pity Mechanics
Character: Soft pity at 74 (31.8% rate), hard at 90. 50/50 system. Worst-case C1: 160 pulls (25,600 Primogems).
Weapon: Hard pity at 80. 75% featured rate (37.5% each if two). Epitomized Path guarantees within 240 pulls. Worst-case Tome: 240 pulls (38,400), realistic 20-80 pulls (3,200-12,800).
Conversion: 160 Primogems = 1 pull. Track pity in wish history—70+ character or 60+ weapon significantly reduces costs.

Player-Specific Scenarios
F2P: Long-Term Value
F2P accumulates 60-80 pulls (9,600-12,800 Primogems) per patch.
Strategy: Prioritize Tome R1 for efficiency (15-20% DPS for 3,200 vs C1's 24% for 12,000-25,600). Tome transfers to future Catalysts. After C0 + Tome R1, save for new characters—roster diversity outperforms hyper-investment.
Exception: If core meta teams complete (National, Hyperbloom, Freeze, Vaporize), C1 viable for optimization.
Low Spenders: Best Value
Welkin + occasional BP = 90-110 pulls (14,400-17,600) per patch.
Strategy: Acquire both Tome R1 + C1 if reserves exceed 28,800 or favorable pity reduces combined cost below 20,000.
Prioritization:
Own Lost Prayer/Skyward Atlas: Pursue C1 only (9-15% gap doesn't justify Tome investment)
Rely on Prototype/Widsith: Pursue Tome R1 first (15-20% gain over 4-stars)
Spending Efficiency: Welkin provides 18.75 pulls/month for $5 (0.267 pulls/dollar). BP adds 8 pulls for $10 (0.128 pulls/dollar). Welkin offers superior ratio.
Collectors vs Meta Chasers
Collectors: Pursue C1 over Tome R1. Constellations represent permanent character progression. Weapons acquire through future banners. C1 = 16.7% progress toward C6.
Meta Chasers: Pursue Tome R1 for primogem-to-performance ratio. 15-20% DPS for 3,200 provides better clear times per primogem. Evaluate whether C1's additional 9% (with Tome) justifies 12,000-25,600 vs new characters.
Own C0: Upgrade or New Character?
Upgrade if:
Neuvillette primary DPS for both Abyss teams
Core meta teams complete
6.4 features low-priority characters
Current Abyss performance 10-20s short of 36-star
New Character if:
Roster lacks key supports (Kazuha, Furina, Xilonen)
6.4 features new Archon/meta-defining character
Struggle due to roster gaps vs individual performance
Neuvillette clears content comfortably at C0
Hybrid: If 28,800+ reserves, acquire Tome R1 (3,200), save 25,600+ for guaranteed 6.4 character.
Common Misconceptions
Myth: C1 Mandatory for Function
Reality: C0 + Prototype Amber achieves 85-90% of C1 performance, clears Abyss 36-star with proper teams (Furina, Kazuha, Zhongli/Layla). C0 clear time: 152s Floor 12 vs C1's 135s. 17s differential = optimization, not viability threshold.
Don't feel pressured—C0 remains top-tier DPS for all endgame content.
Myth: Signature Weapons Always Outperform Constellations
Reality: Holds true for Neuvillette specifically (Tome costs 73-87% less than C1 for 15-20% vs 24% DPS), but doesn't universally apply. Some characters gain disproportionate value from early constellations (Raiden C2, Hu Tao C1).
Evaluate case-by-case. For Neuvillette, Tome offers superior efficiency, but playstyle preferences may justify C1.
Trap: Chasing Both Without Resources
Players with 15,000-20,000 attempt both, assuming favorable luck. When pity disappoints, exhaust reserves without securing either upgrade.
Safe Approach: Calculate worst-case (28,800 for C1, 38,400 for Tome via Epitomized Path). If below 28,800, choose exclusively. Set hard stops (40 pulls on weapon banner, then stop). Track pity real-time, reassess after each 10-pull.
Recovery: If trapped, stop immediately. Save for 6.4. C0 + 4-star remains functional—incomplete progress doesn't justify further depletion.
Reality: Diminishing Returns
Performance curve:
C0 + Prototype: 100% baseline
C0 + Tome R1: 115-120% (+15-20%)
C1 + Prototype: 124% (+24%)
C1 + Tome R1: 135-140% (+35-40%)
C2 + Tome R1: 150-155% (+50-55%)
Efficiency: C0 → C0 + Tome costs 3,200 for 15-20% (0.0047-0.0063% per Primogem). C0 → C1 costs 12,000-25,600 for 24% (0.0009-0.0020%). C1 + Tome → C2 + Tome costs 12,000-25,600 for 10-15% (0.0004-0.0013%).
After C1 + Tome R1, additional investment provides poor efficiency. Set as stopping point unless pursuing C6 completion.
Future-Proofing for 6.4+
Upcoming Synergies
Rumored Hydro Support (6.4): 5-star with Charged Attack DMG amplification and Energy generation. If accurate, enhances both C0 and C1, but disproportionately benefits C0 by compensating missing C1 benefits.
Nahida Rerun (6.4 Phase 1): Enables optimized Hyperbloom. C1 provides significant Hyperbloom advantages through interruption resistance. Plan accordingly.
Cryo DPS (6.5): Leaked meta-defining character. Heavy Neuvillette investment may lack primogems for acquisition. Balance current optimization with future flexibility—preserve 14,400+ for guaranteed new characters.
Recommendation: Monitor 6.4/6.5 beta leaks before finalizing. If high-priority characters imminent, prioritize Tome R1 only (3,200) to preserve resources. If low-priority reruns, pursue both C1 + Tome R1.
Meta Longevity
Current Position: Premier on-field Hydro DPS, outperforms Tartaglia/Ayato in sustained damage. Self-sufficient kit ensures consistent performance.
Power Creep: DPS characters maintain viability 8-12 months before newer releases. Neuvillette released 4.1 (Sept 2023), ~15 months old in 6.3 (Feb 2026). Potential creep within 3-6 months (6.5-7.0).
Archon Privilege: As Fontaine Sovereign, likely receives preferential treatment. Abyss blessings, enemy lineups, artifact sets favor Archon-tier characters, extending meta relevance.
Investment Horizon: Planning to main through 7.0 (~6-8 months)? C1 + Tome R1 provides strong value. Prefer rotating DPS every 3-4 months? Tome R1 only (transferable) offers better returns.
Rerun Schedule
Fontaine characters rerun every 6-8 months. Neuvillette's next rerun likely 8.1-8.3 (~8-12 months from 6.3).
C1 Implication: Skip now = wait 8-12 months, missing benefits for 24 Abyss resets. Opportunity cost justifies pursuing now for immediate optimization.
Tome Implication: Weapon reruns less predictable (12-18 months). But Tome's transferability means lower opportunity cost—substitute Lost Prayer with 9-15% loss until next rerun.
Recommendation: If budget forces choice, prioritize C1 for players valuing immediate optimization unwilling to wait 8-12 months. Prioritize Tome R1 for players comfortable with C0, willing to pursue C1 in future cycles.

FAQ
Is Neuvillette C1 worth pulling in 6.3?
C1 provides 24% DPS boost and interruption resistance. Worth pulling if: running Hyperbloom (close-range benefits), lacking strong shielders, or have 28,800+ Primogems for both C1 + Tome R1. Limited budgets (under 14,400): Tome R1 offers superior efficiency—15-20% DPS for only 3,200 Primogems worst-case.
How much damage does Tome R1 add?
15-20% vs Prototype Amber R5, 18-22% vs Widsith R5. Optimized teams: Tome R1 achieves 1.2M total DPS vs 900K-1M with 4-stars. 42% Charged Attack DMG, 16% HP, 88.2% CRIT DMG create multiplicative scaling for highest damage ceiling.
Primogem cost for guaranteed C1?
12,000-25,600 (75-160 pulls) depending on pity/50/50. 0 pity with 50/50 active: worst-case 160 pulls (90 for potential standard 5-star, 90 for guarantee). 74+ pity with guarantee: only 12,000-14,400.
Can C0 with 4-star weapons clear Abyss 12?
Yes. C0 + Prototype Amber R5 consistently achieves 36-star with proper teams (Furina, Kazuha, Zhongli/Layla). Clear times: 152s Floor 12 vs C1 + Tome's 135s. Represents optimization, not viability threshold. Requires shields or positioning but functions perfectly with proper investment.
Which is better: C1 or signature weapon?
Tome R1 offers superior primogem efficiency (15-20% DPS for 3,200 vs C1's 24% for 12,000-25,600). For pure damage, Tome provides better value. C1 delivers qualitative benefits—interruption resistance, instant stacks, team flexibility—improving gameplay comfort. Choose Tome for damage-per-primogem, C1 for comfort and flexibility.
Primogems for both C1 and Tome R1?
Worst-case: 64,000 (400 pulls)—160 for C1 (25,600) + 240 for Tome via Epitomized Path (38,400). Realistic: 15,200-28,800 assuming average luck—75-90 for C1 (12,000-14,400) + 20-80 for Tome (3,200-12,800). Favorable pity (50+ character, 60+ weapon): 10,000-15,000 for both.
