Columbina & Ineffa's Lunar-Charged Team Best Guide: Dominated in Genshin Impact

With the arrival of the Lunar reaction system in Genshin Impact, two characters have emerged as the core architects of its most powerful team: Columbina and Ineffa. Together, they transform the humble Electro-Charged reaction into the devastating Lunar-Charged reaction, creating a team that is not only top-tier in damage but also redefines elemental synergy. This guide will delve into why the duo of Columbina and Ineffa forms the backbone of the ultimate Lunar-Charged team, exploring their roles, the mechanics, and the best companions to unlock their full potential.

Columbina Overview

 Columbina (also known as the Damselette) is a 5-star Hydro character whose entire kit is designed to empower and evolve the new Lunar reactions.

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

Key Mechanics:

Her passive talent, "Moonsign Benediction: Borrowed Moonlight," is the foundation. It automatically converts ordinary Electro-Charged, Bloom, and Crystallize reactions into their supercharged counterparts: Lunar-Charged, Lunar-Bloom, and Lunar-Crystallize.

Her Elemental Burst, "Moonlit Melancholy," creates a Lunar Domain that provides a significant damage bonus to all Lunar Reaction DMG for the entire team.

Her Elemental Skill, "Eternal Tides," summons a Gravity Ripple. Based on the most-triggered Lunar reaction, its final interference effect can provide different team utilities, such as Energy restoration, Interruption Resistance, or a protective shield.

 

Ineffa Overview

Ineffa is a 5-star Electro polearm user who is specifically tailored to be the engine of the Lunar-Charged reaction.

Rarity：5★｜Element：Electro｜ Weapon: Polearm

Key Mechanics:

Her own passive talent, "Moonsign Benediction: Assemblage Hub," further augments the Base DMG of Lunar-Charged reactions based on her ATK, stacking multiplicatively with Columbina's buffs.

Her summon, Birgitta, coordinated attacks are boosted by the Thunderclouds created by Lunar-Charged reactions, dealing additional AoE Electro DMG.

She provides a sturdy shield based on her ATK with her Elemental Skill and can boost the team's Elemental Mastery with her Elemental Burst, directly increasing reaction damage.

Ineffa doesn't just trigger the reaction; she is built to elevate its damage ceiling and ensure its consistent, high-frequency execution.

 

Understanding the Lunar-Charged Reaction

The Lunar-Charged reaction is a complete overhaul of the traditional Electro-Charged reaction. When Columbina and Ineffa are in a party, any standard Electro-Charged trigger is instantly transformed into a Lunar-Charged reaction.

Key Advantages Over Standard Electro-Charged:

• Structured Damage: Instead of erratic jumps, Lunar-Charged generates a 6-second Thundercloud over enemies. This cloud strikes at fixed intervals, dealing reliable AoE Electro DMG.
• Scales with Crit: Unlike transformative reactions, Lunar-Charged DMG can CRIT, allowing it to benefit from your characters' Critical Rate and Critical Damage stats.
• Team-Wide Contribution: The final damage calculation incorporates the stats of all party members who contribute to the reaction, making it a true team effort.
• Double Frequency: With Columbina's Lunar Domain active, the attack interval of these Thunderclouds is significantly reduced, effectively doubling the damage frequency.

 

Columbina & Ineffa's Best Teams

The premier team composition is: Columbina + Ineffa + Flins + Kazuha.

Columbina

Ineffa

Flins

Kazuha

This quartet is considered the peak Lunar-Charged team, designed for maximum front-loaded damage and crowd control.

Team Rotation:

• Flins: Use Elemental Skill (E) to apply Electro.
• Columbina: Use Elemental Skill & Burst (EQ) to apply Hydro, set up the Gravity Ripple, and most importantly, activate the Lunar Domain for massive reaction DMG bonus.
• Ineffa: Use Elemental Burst & Skill (QE) to summon Birgitta, provide a shield, and apply her Lunar-Charged DMG bonus.
• Kazuha: Use Elemental Skill & Burst (EQ) to Swirl Electro, group enemies, and provide a huge Elemental DMG Bonus and resistance shred via the Viridescent Venerer set.
• Flins: Use Elemental Burst (Q) and take the field, triggering a storm of high-frequency, high-damage Lunar-Charged reactions.

Why This Team is the Strongest:

Perfect Synergy: Flins acts as the perfect on-field driver, rapidly applying Electro to fuel the reactions that Columbina and Ineffa supercharge.

Damage Amplification Stacking: The team layers multiple independent damage multipliers: Columbina's Lunar DMG% bonus, Ineffa's Lunar-Charged Base DMG bonus, and Kazuha's Electro DMG% bonus and resistance shred. This creates a multiplicative damage explosion.

Energy & Control: The double Electro resonance (Ineffa + Flins) improves energy generation for smooth burst rotations. Kazuha's unparalleled grouping ensures every Thundercloud strike hits multiple enemies, maximizing area damage.

 

Columbina & Ineffa's Alternative Teams

The core duo of Columbina and Ineffa is flexible and can anchor other powerful variations:

For Supreme Survivability: Columbina + Ineffa + Flins + Xilonen

Columbina

Ineffa

Flins

Xilonen

Replaces Kazuha with the 5-star Geo support Xilonen. This trade sacrifices some grouping and damage amplification for powerful healing, shielding, and near-unbreakable interruption resistance, making the team nearly invincible in any combat scenario.

For Reaction-Damage Focus: Columbina + Ineffa + Flins + Sucrose

Columbina

Ineffa

Flins

Sucrose

A highly accessible and potent variant. Sucrose replaces Kazuha, providing less direct damage bonus but a massive amount of Elemental Mastery to the entire team. This can sometimes result in even higher Lunar-Charged reaction damage numbers, especially against grouped enemies.

 

Columbina & Ineffa's F2P Teams

For players who may not have all the premium 5-star characters, a highly effective and more accessible team can be built around the core:

Columbina + Ineffa + Fischl + Sucrose

Columbina

Ineffa

Fischl

Sucrose

Fischl replaces Flins as a premier off-field Electro applicator with Oz. While she doesn't drive reactions on-field as intensely, her energy generation and personal damage are exceptional.

Sucrose, as a 4-star character, serves as the perfect Anemo support, providing crowd control, Viridescent shred, and the crucial Elemental Mastery buff.

This team retains the core Lunar-Charged engine (Columbina+Ineffa) and leverages two powerful 4-star units to create a team that is much easier to build but still capable of immense damage output.

 

Conclusion

The partnership between Columbina and Ineffa has established a new paradigm for Electro-based teams in Genshin Impact. By masterfully converting and supercharging the Electro-Charged reaction, they offer a playstyle that is both strategically deep and explosively powerful. Whether you choose the peak performance setup with Kazuha, the unkillable version with Xilonen, or the accessible and potent team with Sucrose, this core duo guarantees a top-tier team capable of dominating the Spiral Abyss and any other challenge Teyvat has to offer.
