Genshin 6.3 Weapon Banner Guide: Moonshard vs Eternal Flow

The Genshin Impact 6.3 Phase 2 weapon banner (February 3-24, 2026) features Lightbearing Moonshard (Zibai's sword) and Tome of the Eternal Flow (Neuvillette's catalyst). Both share 542 Base ATK and 88.2% CRIT DMG at level 90 but serve different archetypes. This analysis examines C0 performance, primogem efficiency, and pull recommendations.

Weapon Banner Overview (February 3-24, 2026)

Epitome Invocation Phase 2 runs three weeks, coinciding with Zibai and Neuvillette rate-ups. 5-star drop rate: 0.7% per pull (160 Primogems each).

Lightbearing Moonshard targets DEF-scaling sword users leveraging Lunar-Crystallize reactions. Tome of the Eternal Flow optimizes HP-scaling catalyst users relying on charged attacks.

For primogem top-ups, Genshin Impact Genesis Crystals through BitTopup offers competitive pricing and instant delivery.

Epitomized Path Mechanics

Guarantees your chosen weapon after 2 Fate Points (max 240 pulls). Hard pity: 80 pulls. Soft pity: 65 pulls. Each off-banner 5-star awards 1 Fate Point.

Critical: Fate Points reset when banners change—progress doesn't transfer.

Version 6.3 F2P primogems: 14,540 (≈107 pulls)—short of 240-pull guarantee (38,400 primogems).

Meta Relevance

February 2026 meta emphasizes reaction-based damage and sustained DPS. Zibai's Lunar-Crystallize introduces defensive scaling; Neuvillette dominates Hydro application. Both perform adequately with 4-stars but signature weapons unlock substantial damage ceilings.

Lightbearing Moonshard Analysis

Genshin Impact Lightbearing Moonshard 5-star sword from 6.3 weapon banner

Zibai's signature sword: 542 Base ATK, 88.2% CRIT DMG at level 90.

Passive Ability

  • R1: DEF +20%, Lunar-Crystallize DMG +64% for 5s after Elemental Skill
  • R5: DEF +40%, Lunar-Crystallize DMG +128%

Synergizes with Zibai's Elemental Skill (10 Phase Shift Radiance/sec) and Normal Attacks (+5 Radiance/0.5s). Spirit Steed's Stride consumes 70 Radiance (15s cooldown).

Ascension Materials

  • Grain of Aerosiderite ×5
  • Mistshroud Manifestation ×23

Zibai Performance (C0)

R1 Damage Comparisons:

  • Lightbearing Moonshard R1: 100% baseline
  • Cinnabar Spindle R5: 82% (-18%)
  • Uraku Misugiri: 95% (-5%)

18% gap = 3-4s faster Spiral Abyss Floor 12 clears.

Alternative Users

Limited compatibility. Current sword users (Ayaka, Keqing, Alhaitham) prioritize ATK/Elemental DMG over DEF. Weapon optimized solely for Zibai and future DEF-scaling sword users.

Optimal Teams

  • Zibai/Xingqiu/Fischl/Zhongli
  • Zibai/Yelan/Kazuha/Bennett
  • Zibai/Furina/Baizhu/Nahida

Tome of the Eternal Flow Analysis

Genshin Impact Tome of the Eternal Flow 5-star catalyst from 6.3 weapon banner

Neuvillette's signature catalyst: 542 Base ATK, 88.2% CRIT DMG.

Passive Ability

  • R1: HP +16%, Charged Attack DMG +14%/stack (max 3), 8 Energy/12s
  • R5: HP +32%, Charged Attack DMG +30%/stack, 12 Energy/12s

Stacks activate within 0.9s (0.3s cooldown). Energy restoration = ≈40 Energy/min.

Ascension Materials

  • Essence of Pure Sacred Dewdrop ×6
  • Alien Life Core ×41

Neuvillette Performance (C0)

R1 establishes damage ceiling. 16% HP bonus scales charged attacks; 42% total charged attack boost (14% × 3). Energy restoration reduces Burst downtime 15-20%.

Versatile Users

  • Neuvillette: Optimal synergy
  • Wriothesley: 5-8% below specialized alternatives
  • Furina: HP scaling benefits, minimal charged attack value
  • Mualani: Functional but suboptimal

Optimal Teams

  • Neuvillette/Furina/Kazuha/Zhongli
  • Neuvillette/Xingqiu/Fischl/Baizhu
  • Neuvillette/Yelan/Nahida/Kuki Shinobu

Head-to-Head Comparison

Comparison of Lightbearing Moonshard and Tome of the Eternal Flow in Genshin Impact 6.3 banner

Shared Stats:

  • Base ATK: 542
  • CRIT DMG: 88.2%
  • Rarity: 5-star limited

Divergent Passives:

  • Moonshard: DEF + Lunar-Crystallize (5s window, precise timing)
  • Tome: HP + Charged Attack + Energy (near-permanent uptime)

Versatility

Moonshard: Zibai-exclusive currently. Future value depends on DEF-scaling sword releases.

Tome: Works across HP-scaling catalysts (Neuvillette, Wriothesley, Furina). Proven mechanics suggest continued relevance.

Future-Proofing

Moonshard's value tied to Lunar-Crystallize adoption (introduced January 14, 2026). Tome benefits from established HP/charged attack mechanics across multiple characters.

4-Star Alternatives

Zibai Options

  • Cinnabar Spindle R5: 82% damage (event-limited)
  • Uraku Misugiri: 95% damage (gacha)
  • Amenoma Kageuchi R5: 70-75% damage (craftable)

18-25% deficit remains viable for all content with optimized artifacts.

Neuvillette Options

  • The Widsith R5: 75-80% damage (gacha)
  • Prototype Amber R5: 65-70% damage (craftable)
  • Hakushin Ring R5: 60-65% damage (craftable)

20-35% deficit doesn't prevent content completion.

When 4-Stars Suffice

F2P weapons work if you:

  • Prioritize roster expansion
  • Don't need consistent 36-star Abyss clears
  • Have strong artifacts compensating deficits
  • Plan future character pulls

12,800 primogems (80 pulls) = half a guaranteed 5-star character.

Wishing Strategy

Primogem Costs

  • Minimum: 160 (0.7% chance)
  • Soft pity: 10,400-12,800 (65-80 pulls)
  • Epitomized Path guarantee: 38,400 (240 pulls)

Expected average: 18,000-22,000 primogems (112-137 pulls).

Decision Framework

Pull if:

  • Own Zibai/Neuvillette as main DPS
  • Have 38,400+ primogems for guarantee
  • Strong artifacts maximize weapon value
  • No upcoming character banner plans (6.4-6.5)
  • Seek optimization over roster expansion

Skip if:

  • Lack featured characters
  • Plan upcoming character pulls
  • Have R3+ 4-star alternatives
  • Below 20,000 primogems
  • Roster gaps exist

Player-Type Recommendations

F2P: Avoid unless 38,400+ primogems and all desired characters secured through 6.5.

Low Spenders (Welkin+BP): Consider if maining featured character with 25,000+ primogems.

Whales: Both worthwhile for collection. Prioritize R1 copies over R5 single weapon.

Common Mistakes

  1. Pulling without Epitomized Path reserves
  2. Pulling without owning featured characters
  3. Ignoring 4-star alternatives
  4. Forgetting Fate Point resets
  5. Weapon banner before character acquisition

Resource Optimization

Ascension Farming

Moonshard: 3-4 Maguu Kenki runs daily (160 Resin) = 2-3 days. Mistshroud domains: 20 Resin/run.

Enhancement Requirements

Level 1→90:

  • Mystic Enhancement Ore ×907
  • Mora ×906,000

Acquisition: Daily routes (30-40 ore), Blacksmith (120/day), Expeditions (10-15/20h), BP (288/period). Total: 7-10 days F2P.

Final Verdict

Choose Moonshard If:

  • Main Zibai as primary DPS
  • Prioritize specialized optimization
  • Plan future DEF-scaling sword pulls
  • Value peak niche performance

Choose Tome If:

  • Main Neuvillette or multiple HP-scaling catalysts
  • Prioritize versatile compatibility
  • Prefer consistent cross-content performance
  • Value future-proof investments

Skip Both If:

  • Lack featured characters
  • Have R3+ 4-star alternatives
  • Plan 6.4-6.5 character pulls
  • Below 25,000 primogems
  • Prioritize roster expansion

Long-Term Value

Tome offers superior versatility—HP scaling and charged attacks span multiple existing characters with proven meta relevance.

Moonshard depends on future Lunar-Crystallize adoption (speculative).

For maximum flexibility: Tome provides safer investment.

Action Steps

  1. Check primogem reserves (need 38,400 for guarantee)
  2. Assess roster (own/use Zibai or Neuvillette?)
  3. Compare 4-star alternatives (performance gap worth cost?)
  4. Review 6.4-6.5 banner schedule
  5. Calculate expected value (damage increase vs character acquisition)

Timeline:

  • Feb 3-10: Monitor community data
  • Feb 10-17: Make preliminary decision
  • Feb 17-24: Execute before deadline

FAQ

Is Lightbearing Moonshard worth pulling for Zibai C0?

Provides 18% more damage than Cinnabar Spindle R5 (3-4s faster Abyss clears). Worth pulling only if you main Zibai, have 38,400+ primogems for guarantee, and skip upcoming characters. F2P should prioritize character acquisition.

How does Epitomized Path work?

Select one featured weapon. Each off-banner 5-star = 1 Fate Point. 2 Fate Points = guaranteed chosen weapon (max 240 pulls/38,400 primogems). Fate Points reset when banner changes—non-transferable.

Average primogem cost for weapon guarantee?

Hard pity: 12,800. Soft pity: 10,400. Epitomized guarantee: 38,400. Average: 18,000-22,000 (accounting for soft pity 65-75). Version 6.3 F2P: 14,540 (insufficient without supplements).

Weapon banner or character constellations?

Character constellations generally provide greater value. C1-C2 often grant 20-40% damage plus QoL improvements, exceeding signature weapons. Weapon investment makes sense only after securing desired characters. F2P: prioritize C0 acquisition.

Signature weapon DPS increase at C0?

Typically 15-25% over best 4-stars. Moonshard: +18% vs Cinnabar Spindle R5. Tome: +20-30% vs craftables. Translates to 3-5s faster Abyss clears but doesn't change content accessibility—all clearable with 4-stars and proper artifacts.

Best 4-star alternatives?

Zibai: Cinnabar Spindle R5 (82%, event-limited), Uraku Misugiri (95%, gacha), Amenoma Kageuchi R5 (70-75%, craftable).

Neuvillette: Widsith R5 (75-80%, gacha), Prototype Amber R5 (65-70%, craftable), Hakushin Ring R5 (60-65%, craftable).

All enable full content completion—signatures are luxury, not necessity.
