Columbina Build Guide: Weapons, Artifacts, Constellations & Teams | Genshin Impact

Hello, Travelers!! In the new chapter of Genshin Impact "Luna IV"—a mysterious figure from Nod-Krai is quietly stepping into the center stage of Teyvat. She is the enigmatic Damselette among the Fatui Harbingers: Columbina Hyposelenia. As a 5-star Hydro Catalyst character and the core of the new "Lunar Reaction" system, her arrival is highly anticipated. This comprehensive guide will analyze her optimal build for you. Let's dive in!

Columbina Overview

Rarity: 5★ | Element: Hydro | Weapon: Catalyst | Ascension Stat: CRIT Rate +19.2%

Columbina is a Hydro Catalyst user whose role is that of a dedicated support/sub-DPS for the Lunar Reaction system. Her core value lies in significantly boosting the damage of her team's Lunar-Charged, Lunar-Bloom, and Lunar-Crystallize reactions while optimizing team rotations. Notably, her mechanics are deeply intertwined with characters from Nod-Krai, making her both a powerful engine for the new system and potentially limiting her versatility.

Understanding Columbina's Kit

Normal/Charged Attack: Moondew Cascade

Normal Attack: Summons Moonlit Tides, performing up to 3 attacks that deal Hydro DMG.

Charged Attack - Moondew Cleanse: When the party has at least 1 Verdant Dew, consume 1 to unleash a Charged Attack that deals Dendro DMG (considered Lunar-Bloom DMG) without consuming Stamina.

Plunging Attack: Plunges towards the ground from mid-air, damaging all opponents in her path. Deals AoE Hydro DMG upon impact with the ground.

Elemental Skill: Eternal Tides

Deals AoE Hydro DMG and summons a Gravity Ripple that follows the active character, dealing continuous Hydro DMG.

Core Mechanic - Gravity: While the Ripple exists, triggering Lunar Reactions accumulates Gravity for Columbina. Upon reaching max Gravity, it triggers Kuuvahki Interference, dealing massive AoE DMG of a specific element (Electro/Dendro/Geo) based on the most-triggered Lunar Reaction type. This is key to her off-field damage.

Elemental Burst: Moonlit Melancholy

Creates a Lunar Domain, dealing AoE Hydro DMG and increasing all Lunar Reaction DMG dealt by characters within it. This is the core team buff.

Key Passive Talents

Moonsign Benediction: Borrowed Moonlight (A1): Converts triggered Electro-Charged/Bloom/Hydro-Crystallize reactions into their enhanced Lunar counterparts. Also increases the Base DMG of Lunar Reactions based on Columbina's Max HP.

Law of the New Moon (A4):

When characters within the Lunar Domain trigger Lunar reactions, they will gain the following effects respectively:

• Lunar-Charged: Thundercloud attack interval is reduced by 0.5s.
• Lunar-Bloom: When triggering Lunar-Bloom reactions, the party gains a special Moonridge Dew. Up to 3 Moonridge Dews can be gained every 18s.
• Lunar-Crystallize: When Moondrift Harmony is triggered, every Moondrift has a 33% chance to inflict an extra attack.

Grants additional effects when triggering Lunar Reactions inside the Lunar Domain (e.g., reduced attack interval for Lunar-Charged, generates special resources).

Call of the Moon: When triggering Kuuvahki Interference, Columbina gains the Lunacy effect, increasing her CRIT Rate by 5% for 10s. This effect can be stacked up to 3 times..

Talent Priority

Based on the above analysis of Columbina’s kit, the Skill Priority is quite clear, the Normal Attack is not important, so we can ignore it. You should make sure upgrade Elemental Skill and Burst to level 10.

Talent	Priority
Elemental Skill (E)	⭐⭐⭐⭐⭐ (Highest)
Elemental Burst (Q)	⭐⭐⭐⭐ (High)
Normal Attack (A)	⭐⭐⭐ (Low)

Elemental Skill (E): Directly increases the damage of Gravity Ripple and Kuuvahki Interference.

Elemental Burst (Q): Upgrades the valuable team-wide Lunar Reaction DMG bonus.

Normal Attack (A): Only level if you plan to use her on-field for Charged Attacks.

Upgrade Order: Elemental Skill (E) ≥ Elemental Burst (Q) > Normal Attack (A)

Columbina Best Artifacts

With the introduction of the Luna reaction system, two new artifact sets have become core. "Dawnstar and Moon's Morning Song" and "Sewn Moon's Nocturne" are tailored for support, while "Night of Revelation in the Firmament" is for sub-DPS.

For a Support Focus

Aubade of Morningstar and Moon

• 2P Increases Elemental Mastery by 80.
• 4P When the equipping character is off-field, Lunar Reaction DMG is increased by 20%. When the party's Moonsign Level is at least Ascendant Gleam, Lunar Reaction DMG will be further increased by 40%. This effect will disappear after the equipping character is active for 3s.

This set offers the most straightforward and potent damage multiplier for her off-field role. Since Columbina's kit easily fulfills the "Full Radiance" condition, she can consistently enjoy the full 60% Lunar Reaction DMG bonus, making it a perfect match.

Silken Moon's Serenade

• 2P Energy Recharge +20%.
• 4P When dealing Elemental DMG, gain the Gleaming Moon: Devotion effect for 8s: Increases all party members' Elemental Mastery by 60/120 when the party's Moonsign is Nascent Gleam/Ascendant Gleam. The equipping character can trigger this effect while off-field. All party members' Lunar Reaction DMG is increased by 10% for each different Gleaming Moon effect that party members have. Effects from Gleaming Moon cannot stack.

A fantastic support set that provides needed Energy Recharge, team-wide EM, and a direct damage multiplier for the entire team's Lunar Reactions.

For a Sub-DPS Focus

Night of the Sky's Unveiling

• 2P Increases Elemental Mastery by 80.
• 4P When nearby party members trigger Lunar Reactions, if the equipping character is on the field, gain the Gleaming Moon: Intent effect for 4s: Increases CRIT Rate by 15%/30% when the party's Moonsign is Nascent Gleam/Ascendant Gleam. All party members' Lunar Reaction DMG is increased by 10% for each different Gleaming Moon effect that party members have. Effects from Gleaming Moon cannot stack.

Maximizes her personal damage output by providing EM, CRIT Rate, and the same team-wide Lunar Reaction DMG bonus. Ideal if she is triggering reactions frequently while on-field.

Main & Sub Stat Priority

Main Stat Priority

Sands of Eon	HP% or Energy Recharge%
Goblet of Eonothem	HP% or Hydro DMG Bonus%
Circlet of Logos	CRIT Rate or CRIT DMG

Substat Priority: CRIT Rate/CRIT DMG > HP% > Energy Recharge%

Energy Recharge Goal: Aim for 140%-160% to ensure consistent Burst uptime, adjusting based on your team composition.

 

Columbina Best Teams

Columbina is a dedicated support for the Nod-Krai system. Team building revolves around the three Lunar Reactions.

Lunar-Bloom Team

Nafer + Lauma + Columbina + Nahida/Baizhu

Nafer	Lauma	Columbina	Nahida
Nafer	Lauma	Columbina	Baizhu

Columbina provides off-field Hydro, boosts Lunar-Bloom DMG, and optimizes the team's Verdant Dew resource cycle. Nafir acts as the on-field driver and core damage dealer.

Lunar-Charged Team

Flins + Ineffa + Columbina + Kazuha/Sucrose/Xilonen

Flins	Ineffa	Columbina	Kazuha
Flins	Ineffa	Columbina	Xilonen
Flins	Ineffa	Columbina	Sucrose

Columbina enables and massively amplifies Lunar-Charged reactions for the dual Electro core. An Anemo support groups enemies, provides RES Shred, and buffs Elemental Mastery.

Lunar-Crystallize Team

Zibai + Illuga + Columbina + Gorou/Xilonen/Chiori

Zibai	Illuga	Columbina	Gorou
Zibai	Illuga	Columbina	Xilonen
Zibai	Illuga	Columbina	Chiori

A new team built around the Geo DPS Zibai (expected in 6.3) and his dedicated support, Ye Luoya. Columbina applies Hydro to trigger Lunar-Crystallize reactions and provides the team-wide damage bonus, acting as a key enabler.

 

Constellation Recommendations

Key Constellations: C1, C2, C6

C1 - "Radiance Over Blossoms and Peaks": Using her Elemental Skill immediately triggers Kuuvahki Interference and provides additional team utility (Energy, Shield, etc.) based on the reaction type. A significant quality-of-life and power boost that improves rotations.

C2 - "Not in Lone Splendor": Increases Gravity accumulation rate. Upon triggering Interference, increases Columbina's own Max HP and grants ATK/EM/DEF to the active character based on the reaction type. A major boost to her personal and team support capabilities.

C6 - "Through Darkness Led by Moonlight": After triggering a Lunar Reaction inside her Burst's Lunar Domain, the party's CRIT DMG for the corresponding Elemental DMG is greatly increased for a duration. This is a transformative, massive damage increase for specialized teams.

Pulling Advice: For players who want to experience her complete and smoothest gameplay, C2 is highly recommended as it provides comprehensive enhancements.

Conclusion

And that wraps up the most complete and powerful build guide for Columbina Hyposelenia!! Columbina is a character with a very clear design purpose: a "System-Dedicated Support." For Travelers who have already invested in or plan to build a Lunar Reaction team, she is an indispensable core unit that can dramatically elevate the potential of teams built around Nafer, Flins, or the upcoming Zibai.

However, her deep mechanical ties to Nod-Krai characters mean her versatility in traditional team compositions is likely limited. Consider your existing roster and Primogem reserves carefully before deciding to invite her aboard your journey.
