Columbina, the enigmatic Fatui Harbinger known as Damselette or the Moon Maiden, is rumored to debut as a 5-star Hydro Catalyst in the first phase of Version 6.3 (around January 2026). Her kit positions her as an off-field sub-DPS and universal buffer for Lunar Reactions (Lunar-Charged, Lunar-Bloom, and Lunar-Crystallize), enabling conversions from standard reactions and providing teamwide enhancements.

Leaked by credible sources X1, Hiragara, and Seele-Leaks, her abilities revolve around Hydro application, Gravity accumulation via Lunar triggers, and a domain buff field. She scales primarily with Max HP for damage and buffs, alongside CRIT stats. 

Disclaimer: The following information is based on recent leaks and is subject to change. Official details will be confirmed during the Version 6.3 beta, starting December 3, 2025.

Normal Attack: Moonlit Dewfall

Columbina summons tides of moonlit waters for up to three consecutive Hydro-infused strikes.

  • Charged Attack: Consumes stamina for a brief AoE Hydro DMG blast. If at least one Verdant Dew is available, it is replaced by a stamina-free Moondew Purge, consuming one Verdant Dew to deal three instances of AoE Dendro DMG (considered Lunar-Bloom Reaction DMG).
  • Plunging Attack: Dives from mid-air to deal AoE Hydro DMG on impact.

Elemental Skill: Tides of the Everdeep

Calls upon the tides of the Moonsea, dealing AoE Hydro DMG and summoning a Gravitational Ripple:

  • Follows the active character and deals continuous AoE Hydro DMG to nearby enemies.
  • When nearby party members trigger a Lunar Reaction or deal Lunar Reaction DMG, Columbina gains Newmoon's Omen for 2s, accumulating 20 Gravity every 2s (max 60 Gravity, removed on Ripple expiry).
  • At max Gravity, triggers Tidal Interference based on the most accumulated Lunar Reaction type:
Dominant Lunar ReactionTidal Interference Effect
Lunar-ChargedDeals AoE Electro DMG (treated as Lunar-Charged DMG)
Lunar-BloomFires 5 Moondew Marks at nearby enemies (treated as Lunar-Bloom DMG)
Lunar-CrystallizeDeals AoE Geo DMG (treated as Lunar-Crystallize DMG)

This makes her Skill her primary off-field damage source, with strong Hydro application and adaptive Lunar follow-ups.

Elemental Burst: Her Homeland's Longing

By the name of the unsullied new moon, reshapes the land into a Moonlit Domain and deals AoE Hydro DMG.

  • Moonlit Domain: While inside, all party members gain increased Lunar Reaction DMG.
  • Duration: 20s
  • Cooldown: 15s
  • Energy Cost: 60

Her Burst acts as a Nahida-like field, amplifying team Lunar output.

Passive Talents

Columbina's passives enhance her Tidal Interference, convert standard reactions, and provide utility.

  • 1st Passive (Lunacy Beneath the Moonlight): When Tidal Interference triggers, Columbina gains Moonmaddened (+5% CRIT Rate for 10s, max 3 stacks).
  • 2nd Passive (Moonsign's Benediction - "Lend Me Your Moonlight"): Party-triggered Electro-Charged/Bloom/Hydro Crystallize converts to Lunar variants. Increases party base Lunar Reaction DMG by 0.2% per 1,000 Max HP (up to 7%). While in party, Moonsign level +1.
  • 4th Passive (Law of the Crescent): Inside Moonlit Domain, Lunar Reactions grant:
Lunar ReactionEffect
Lunar Electro-ChargedStormcloud attack interval -0.5s
Lunar-BloomGrants 1 Mountain Lunar Ward Verdant Dew (33% chance for max 3 to strike again)
Lunar-Crystallize33% chance per Lunar Ward in Resonance to strike again
  • Utility Passive (Watcher of the Moon): In Nod-Krai, revives and heals a fallen party member (scales with Friendship level; once every 100s). Attracts small creatures touched by Kuuvahki.

Constellations

Columbina's constellations boost her immediately, with each adding ~3% party Lunar Reaction DMG (C6: 5%; total C1-C6: 20%). They enhance Tidal Interference triggers, provide personal buffs, and unlock hybrid DPS potential.

ConstellationNameKey Effects
C1Blooming Plains Beneath Hidden PeaksSkill immediately triggers 1 Tidal Interference (once/15s). Moonsign: Ascendant Gleam - Post-trigger (dominant type): Lunar-Charged restores 6 Energy; Lunar-Bloom + Interruption RES (8s); Lunar-Crystallize summons Hydro shield (12% Max HP absorption, 250% Hydro, 8s). +3% party Lunar DMG.
C2Radiant Companion Through the Night+34% Gravity accumulation. Post-Tidal: +30% Max HP (8s, Moonlit Grace). Active char buffs (0.7% her Max HP ATK / 0.35% EM / 0.7% DEF). +3% party Lunar DMG.
C4Clouds Among Blossoms, Shadows Over StonePost-Tidal: Restore 4 Energy. +Tidal DMG (Max HP): Lunar-Charged/Bloom/Crystallize +12.5%/2.5%/12.5% (once/15s). +3% party Lunar DMG.
C6Light of the Moon Through Darkened SkiesIn Domain, post-Lunar Reaction: +80% CRIT DMG to matching Elemental DMG (8s, same element no stack). +5% party Lunar DMG.

C3 and C5 likely raise Skill/Burst levels +3 (standard pattern).

Columbina's leaked kit cements her as a Lunar meta staple, synergizing with Nod-Krai characters while offering flexibility via conversions. Her C0 viability is high for sub-DPS/support, with constellations elevating her to premium buffer/DPS hybrid. Stay tuned for beta updates!
