Genshin Impact Version 6.3 launches January 14, 2026, introducing Columbina as a 5-star Hydro Catalyst with revolutionary Lunar Reaction mechanics. This leak analysis covers her complete kit, new Lunar-Charged/Bloom/Crystallize reactions, artifacts, teams, and the Hydro domain system. Expect transformative gameplay through her Lunar Domain burst and Gravity Ripple skill, supported by artifacts providing up to 40% Lunar Reaction damage bonuses.
Genshin Impact 6.3 Overview: Lunar Shield Update
Version 6.3 releases January 14, 2026. Special Program livestream: January 2, 2026 at 12:00 AM UTC-5. This update reshapes Hydro reactions through Lunar Reactions—enhanced versions of Electro-Charged, Bloom, and Crystallize that scale with Max HP.
Three new characters: Columbina (5★ Hydro Catalyst), Zibai (5★ Geo Sword), Illuga (4★ Geo Polearm). Neuvillette gets a new skin. Phase 1 features Columbina with Illuga/Ineffa; Phase 2 pairs Zibai with Neuvillette/Ineffa.
For primogems, Genshin Impact top up via BitTopup offers competitive pricing and instant delivery.
Lunar Shield System
Lunar Crystallization generates three orbiting Lunar Wards when Geo and Hydro interact. These wards trigger CRIT-able AOE Geo Resonance damage after three activations, transforming defense into offense.
Zibai's enhanced fourth Normal Attack triggers Lunar-Crystallize via Ascended Gleam passive. Illuga's Nightingale's Song burst provides 20-second buffs stacking to boost Geo and reaction damage based on EM.
Lunar Reaction base damage increases 0.2% per 1000 Max HP, capping at 7% bonus (35,000 HP). This incentivizes HP builds while maintaining competitive damage.
Hydro Reaction Domain Mechanics
Columbina's Lunar Domain (Elemental Burst Moonlit Melancholy) converts standard reactions to enhanced Lunar variants. Moonsign Benediction passive auto-converts Electro-Charged to Lunar-Charged, Bloom to Lunar-Bloom, Hydro-Crystallize to Lunar-Crystallize.
Lunar-Charged: Electro AOE via thunderclouds with 0.5s intervals (vs standard Electro-Charged)
Lunar-Bloom: Dendro damage + Moonridge Dew stacks (max 3 every 18s) Lunar-Crystallize: 33% extra attack damage per activation
Gravity Ripple summon (Elemental Skill Eternal Tides) accumulates 20 Gravity every 2s up to 60 max, then unleashes Kuuvahki Interference triggering all three Lunar reactions simultaneously.
Leak Credibility
Beta data historically undergoes 15-20% adjustment pre-release. Multipliers, energy costs, cooldowns are most volatile. Core mechanics (Lunar conversion, Gravity accumulation) typically remain intact.
Aubade of Morningstar and Moon artifact specs show high consistency across leak sources: 2pc +80 EM, 4pc +20% off-field Lunar Reaction damage.
Columbina Character Analysis
First playable Fatui Harbinger. Hydro Catalyst scaling with Max HP. Ascension stat: +19.2% CRIT Rate at level 90.
Signature weapon Nocturne's Curtain Call: 542 Base ATK, +88.2% CRIT DMG, passive grants 10-18% Max HP and recovers 12-16 Energy every 18s.
Level 90 Stats
35,000 Max HP achieves 7% maximum Lunar Reaction bonus (HP% Sands, Hydro DMG Goblet, moderate HP% substats). Normal Attack Moondew Cascade delivers 3 Hydro damage instances.
Moondew Cleanse consumes 1 Verdant Dew for 3 AOE Dendro Lunar-Bloom instances—self-sufficient Bloom without Dendro supports.
Lunacy passive: +5% CRIT Rate per stack for 10s (max 3 stacks = +15%). Combined with ascension stat = 34.2% CRIT Rate before artifacts.
Ascension Materials
Total: 46 Radiant Antler, 168 Winter Icelea, 420,000 Mora. Radiant Antler drops from Columbina's Wings region. Winter Icelea: 48hr respawn regional specialty.
Talents: 3 Crowns, 114 Philosophies of Moonlight, 4,957,500 Mora. Moonlight books drop Tuesdays/Fridays/Sundays.
Kit Breakdown
Elemental Skill: Eternal Tides
AOE Hydro damage + summons Gravity Ripple. Accumulates Gravity every 2s regardless of active character. At 60 Gravity, Kuuvahki Interference auto-triggers Lunar-Charged, Lunar-Bloom, Lunar-Crystallize based on active auras.
Deploy after applying Electro/Dendro/Geo auras. 6s accumulation creates rotation windows for supports. Switch immediately after cast—Gravity accumulates during off-field time.
Elemental Burst: Moonlit Melancholy
AOE Hydro damage + creates Lunar Domain. Domain persists through character swaps. Scales with Max HP.
All eligible reactions auto-convert to Lunar variants. 80 Energy cost requires 130-150% ER (110-120% with Nocturne's Curtain Call).
Passive Talents
Law of the New Moon: Reduced Lunar-Charged intervals (0.5s), Moonridge Dew accumulation (3 stacks/18s), +33% attack damage for Lunar-Crystallize.
Call of the Moon: Lunacy stacks grant +5% CRIT Rate per stack (max +15% for 10s).
Moonsign Benediction: Auto reaction conversion—no manual triggers needed.
Constellations
C0: Complete functional gameplay. C1 Radiance Over Blossoms and Peaks: Kuuvahki Interference every 15s independent of Gravity. ~35-40% damage increase. C2 Not in Lone Splendor: +34% Gravity accumulation, +30% Max HP during Lunar Brilliance (8s). C4 Cloudveiled Ridges: Restores 4 Energy, +12.5% Max HP Lunar Reaction damage every 15s. C6 Through Darkness Led by Moonlight: +80% CRIT DMG to Lunar reactions for 8s per element. 60-80% damage increase over C0 in triple-reaction teams.

Meta Comparison
vs Yelan: Yelan excels single-target. Columbina superior AOE (3+ enemies). Use Yelan for bosses, Columbina for multi-target.
vs Neuvillette: Neuvillette = on-field Charged Attack DPS, self-sufficient. Columbina requires coordinated teams but higher damage ceiling with proper support.
vs Kokomi: Kokomi = unmatched healing + 100% Hydro uptime. Columbina = offensive Lunar Reactions, needs dedicated healer. Kokomi for sustain, Columbina for damage checks.
Hydro Reaction Domains
Columbina's Wings region hosts new domains with Hydro-resistant enemies (70% Hydro resistance). Rewards Aubade artifacts.
Team Comps
Lunar-Charged: Columbina, Fischl, Kazuha, Zhongli Lunar-Bloom: Columbina, Nahida, Dendro Traveler, Kuki Shinobu Lunar-Crystallize: Columbina, Zibai, Illuga, Bennett

Advanced Tips
Rotation Optimization
Apply support elements BEFORE Lunar Domain. Pre-applying Electro/Dendro/Geo ensures immediate reactions, maximizing burst windows.
Correct: Support elements → Columbina Skill → Columbina Burst → Sustained Hydro Wrong: Columbina Burst first (wastes 2-3s domain duration, -15-20% reactions)
Energy Management
Funnel particles to Columbina during skill cooldowns. Switch to her after support skills for +3-4 energy/rotation.
Include energy generator (Fischl, Xingqiu, Raiden). Without battery, ER needs 150-170%.
Test: If burst ready 2-3s after cooldown = sufficient ER. 5s+ delay = increase ER 10-20%.
Common Mistakes
Over-investing EM: 200 EM + 70/140 CRIT outperforms 400+ EM + 50/100 CRIT by 15-25%
Neglecting ER: High CRIT DMG useless without burst uptime
Healing Bonus circlet with Prototype Amber: Use HP% (healing scales HP, not Healing Bonus)
Ignoring talents: Levels 8→10 = 8-12% damage, cheaper than artifact grinding
Beta Changes
60-70% of beta kits reach live with minimal changes. Numerical adjustments (±15%) occur in 40-50% of cases.
Lunar conversion mechanics show high stability. Assume 10-15% multiplier reduction from beta. Evaluate C0 as baseline.
Future-Proofing
Hydro universally valuable. Columbina's unique Lunar mechanics create distinct niche, preserving long-term value.
Aubade set applies to any Lunar Reaction character—future releases may expand roster. Early investment transfers to new characters.
C1 recommended for meaningful power increase (Kuuvahki frequency doubling) without excessive spending.
