Ineffa debuts in Genshin Impact as the first playable character from Nod-Krai, introducing a new elemental reaction called Lunar-Charged. This enhanced version of Electro-Charged allows her to trigger CRIT-capable reaction damage while providing shields, off-field Electro application, and team Elemental Mastery buffs.
Whether you plan to pull for Ineffa or want to maximize her potential in reaction-based teams, this guide covers the best Ineffa build, including weapons, artifacts, stat priorities, and team compositions to make the most of her kit.
How Ineffa Works in Genshin Impact
- Element: Electro
- Weapon: Polearm
- Rarity: 5-Star
- Role: Support / Sub-DPS
Ineffa’s kit revolves around off-field Electro application, shielding, and Lunar-Charged reactions, which convert standard Electro-Charged triggers into a unique reaction capable of critical hits. This makes her a flexible support or sub-DPS who enhances reaction-based team damage.

Her Elemental Skill summons Birgitta, her Smart Assistance Unit, while also generating an Optical Flow Shield Barrier that scales on ATK.
- The shield lasts 20 seconds with a 16-second cooldown, allowing for near-permanent uptime.
- It absorbs 250% more Electro damage, making it highly reliable against Electro-heavy content.
- Birgitta attacks every 2 seconds, dealing consistent off-field Electro damage to enemies.
Her Elemental Burst deals AoE Electro damage, refreshes Birgitta’s uptime, and activates her passive that boosts team Elemental Mastery, making her a strong enabler for reaction teams.
The Lunar-Charged reaction is the highlight of her kit:
- It can CRIT, unlike standard Electro-Charged.
- It scales on both ATK and Elemental Mastery, with her passives increasing its base damage per 100 ATK.
- This synergy makes ATK% her most important stat, with EM as a valuable secondary for reaction-focused builds.
Talent Priority:
- Elemental Skill – Core of her kit and shield uptime
- Elemental Burst – Extends Birgitta and activates team buffs
- Normal Attack – Low value; can remain at level 1

- A4: Using Burst grants 20s of Elemental Mastery buff to the team (6% of Ineffa’s ATK).
- Moonsign Benediction: Converts Electro-Charged → Lunar-Charged; +0.7% base DMG per 100 ATK (max 14%).
These passives make ATK% her primary stat focus, with EM as a secondary for reactions.
Ineffa Constellations and Their Effects
| Constellation | Effect & Notes |
|---|---|
| C1 | Increases team Lunar-Charged DMG by 2.5% per 100 ATK (up to 50%). Great future-proof buff. |
| C2 | Burst triggers 300% ATK AoE Lunar-Charged DMG; grants shields to allies. Big AoE spike. |
| C3 | Skill +3 levels; minor personal DMG boost. |
| C4 | Restores 5 energy per Lunar-Charged trigger (every 4s). Major ER reduction. |
| C5 | Burst +3 levels; minor impact. |
| C6 | Adds extra AoE Lunar-Charged strike every 3.5s near active character. |
C0 is fully functional, but C4 and C6 provide strong energy and damage quality-of-life.
Best Weapons for Ineffa
Ineffa performs well with both supportive and offensive polearms, with her signature weapon being the strongest option.
| Weapon | Why It’s Good |
|---|---|
| Fractured Halo (5★) | BiS weapon. High CRIT DMG, boosts ATK after Skill/Burst, and increases team Lunar-Charged DMG. |
| Calamity Queller (5★) | Provides massive ATK% and boosts damage even when Ineffa is off-field. |
| Engulfing Lightning (5★) | Fixes Energy Recharge needs and grants ATK% scaling with ER. |
| Staff of the Scarlet Sands (5★) | CRIT Rate polearm that scales ATK with Elemental Mastery. |
| Vortex Vanquisher (5★) | Excellent when shielded, giving a strong ATK% boost for on-field play. |
| Deathmatch (4★ BP) | CRIT Rate polearm that boosts ATK; great for hybrid Sub-DPS roles. |
| Kitain Cross Spear (4★ F2P) | Craftable, offers EM and energy generation; ideal for budget builds. |
Tip for F2P Players: Kitain Cross Spear or Favonius Lance are strong early options for energy consistency and off-field utility.

Ineffa currently has no dedicated artifact set, but several existing sets complement her off-field and reaction-focused playstyle.
