Ineffa Build Guide: Best Relics, Weapons & Teams | Genshin 7.1
2026-09-04
Ineffa is a 5-star Electro Polearm character built around the Lunar-Charged reaction introduced with the Nod-Krai era. Her kit combines reliable off-field Electro application with a strong shield, while her passive abilities turn Lunar-Charged reactions into a major source of personal damage.
She is played as an off-field Sub-DPS who enters the field to cast her Skill and Burst before handing control to the team's main damage dealer. Her long-lasting companion, Birgitta, keeps attacking independently and also enables the Lunar-Charged reactions that power much of Ineffa's damage.
This Genshin Impact Ineffa build guide covers her kit, best weapons, artifact sets, stat priorities, team compositions, talent investment, and Constellations so you can build her for Lunar-Charged teams or other reaction-based compositions.
Ineffa Character Overview
 | Rarity | 5 star |
| Element | Electro | |
| Weapon | Polearm | |
| Combat Role | Off-field Sub-DPS / Shielder / Lunar-Charged Enabler |
Ineffa's gameplay focuses on Cleaning Mode: Carrier Frequency, which deals AoE Electro DMG and creates her shield. It also summons Birgitta. The shield scales from Ineffa's ATK and has 250% absorption effectiveness against Electro DMG, while Birgitta remains active for 20 seconds and attacks nearby enemies every 2 seconds.
The real strength of the Genshin Ineffa build appears when Hydro is present. Ineffa converts Electro-Charged into Lunar-Charged, and this reaction's damage formula takes the EM and CRIT stats of the Electro and Hydro characters involved into account. Her own passive also increases Lunar-Charged Base DMG based on her ATK, reaching its maximum bonus at 2,000 ATK.
Ineffa Skills and Kit
Normal Attack: Cyclonic Duster
Genshin Impact Ineffa performs up to four consecutive polearm strikes, along with standard Charged and Plunging Attacks. These attacks contribute very little to her normal rotations, so they are generally left at low talent levels.
Elemental Skill: Cleaning Mode: Carrier Frequency
Ineffa's Elemental Skill deals AoE Electro DMG and creates the Optical Flow Shield Barrier. It also summons Birgitta. The shield and Birgitta last 20 seconds, while Birgitta repeatedly attacks nearby enemies throughout that duration. Birgitta's attacks occur every 2 seconds, which gives Ineffa sustained off-field Electro application for Lunar-Charged teams.
Elemental Burst: Supreme Instruction: Cyclonic Exterminator
Ineffa launches Birgitta at the target and deals a powerful AoE Electro hit. If Birgitta is already active, the Burst refreshes her duration instead of leaving a second Birgitta on the field. The Burst costs 60 Energy and has a 15-second cooldown.
Passive Talents
Ascension Passive: Overclocking Circuit
Whenever Birgitta attacks while Lunar-Charged thunderclouds are present, she gains an additional attack that deals 65% of Ineffa's ATK as Lunar-Charged DMG. These extra hits account for a large portion of Ineffa's personal damage.
Ascension Passive: Panoramic Permutation Protocol
Casting Ineffa's Burst grants herself and the active character Elemental Mastery equal to 6% of Ineffa's ATK for 20 seconds. This gives her another reason to prioritize ATK, especially when supporting reaction-focused carries.
Moonsign Benediction: Assemblage Hub
Ineffa build changes Electro-Charged into Lunar-Charged and increases its Base DMG by 0.7% for every 100 ATK she has, up to 14% at 2,000 ATK. She also raises the team's Moonsign Level by one, which unlocks additional benefits for Nod-Krai characters and certain weapons and artifact effects.
Ineffa Talent Priority
Elemental Skill > Elemental Burst > Normal Attack
Ineffa's Elemental Skill directly affects the strength of her shield, while Elemental Burst improves an additional part of her damage. Normal Attack can remain unlevelled for her standard off-field playstyle.

Ineffa Best Weapons
Ineffa Signature Weapon: Fractured Halo
Fractured Halo is the best overall Ineffa weapon. It provides 608 Base ATK and 66.2% CRIT DMG, while its passive grants 24% ATK for 20 seconds after using a Skill or Burst. Creating a shield during this effect also gives the entire nearby party up to 40% Lunar-Charged DMG at R1, which makes it excellent for Ineffa's personal output and overall team damage.
Ineffa Alternative Weapons
Staff of the Scarlet Sands
Staff of the Scarlet Sands is one of Ineffa's strongest alternatives due to its CRIT Rate and EM-to-ATK conversion. It becomes attractive when Ineffa can stay on the field long enough to maintain the weapon's passive, and EM can become more competitive with ATK when using this weapon.
Bloodsoaked Ruins
Bloodsoaked Ruins is another powerful 5-star option because its passive can restore 12 Energy after Ineffa triggers a Lunar-Charged reaction, helping reduce her ER requirements. Its Lunar-Charged DMG and CRIT DMG bonuses also improve her personal output during the weapon's short active windows.
Deathmatch
Deathmatch is a strong 4-star Ineffa weapon. Its performance is good against a single target, and at high refinement it can compete with several premium 5-star weapons.
Prospector's Shovel
For teams reaching Moonsign: Ascendant Gleam, Prospector's Shovel is Ineffa's best 4-star weapon. Its ATK% secondary stat and up to 48% Lunar-Charged DMG at R5 make it particularly effective in Ascendant Gleam teams.
Best Ineffa F2P Weapons
Kitain Cross Spear is useful when Ineffa faces high ER requirements because its passive can reduce the amount of ER she needs. Favonius Lance is another utility-focused option when team Energy matters more than Ineffa's own damage. At Ascendant Gleam, Prospector's Shovel is a strong F2P-friendly choice.
Ineffa Best Artifacts & Stats
Aubade of Morningstar and Moon (4-Piece)
It is Ineffa's best artifact for personal damage when another Moonsign character is present. It provides 80 EM through its 2-piece effect and a strong Lunar Reaction DMG increase. So, it is the preferred damage-focused set in many Lunar-Charged teams.
Silken Moon's Serenade (4-Piece)
It is a strong alternative for the Ineffa Genshin build when Ineffa is the team's holder for its support effect. Its long-lasting Skill makes maintaining the set easy, and it can provide 60 or 120 teamwide EM depending on Moonsign level, alongside a Lunar Reaction DMG Bonus. In many teams, another character holding this set allows Ineffa to use Aubade for more serious personal damage.
Gilded Dreams (4-Piece)
It is a practical farming placeholder that provides useful EM and ATK. Support sets such as Tenacity of the Millelith, Noblesse Oblige, and Scroll of the Hero of Cinder City can also be used when team utility takes priority over Ineffa's personal damage.
Ineffa Stat Priority
| Main Stat | Sands: ATK% > EM / ERGoblet: ATK% > EMCirclet: CRIT Rate / CRIT DMG |
Substats: Energy Recharge (if you want to use Burst) > CRIT > ATK% > EM
Ineffa Best Teams
Lunar-Charged Teams
Lunar-Charged is Ineffa's primary team archetype, so consistent Hydro application is essential. Ineffa generally stays off-field while Birgitta supplies Electro application and passive damage, with Hydro teammates keeping the reaction active. A second Moonsign character is desirable because it unlocks additional gear and team benefits tied to Ascendant Gleam.
This is a strong Lunar-Charged Ineffa build team. Flins and Ineffa provide the Moonsign synergy, while Columbina supplies powerful Hydro support and Sucrose can contribute grouping and EM utility.
 Ineffa |  Flins |  Aino |  Sucrose |
This is a more accessible variation. Aino provides off-field Hydro application and additional Moonsign synergy, while Sucrose contributes EM and Anemo utility.
Neuvillette Lunar-Charged Team
 Ineffa |  Neuvillette |  Furina |  Kazuha |
This Ineffa best team combination gives Ineffa a defensive role alongside her off-field damage. Neuvillette benefits from the shield during his field time, while Furina and Kazuha provide powerful support.
Ineffa Constellations
Ineffa is functional at C0, with her Constellations increasing Lunar-Charged damage, shield uptime, Energy economy, and personal DPS. C1 and C2 offer useful upgrades early on, while C6 delivers the largest increase to her personal output.
| Constellation | Rating | Quick Take |
| C1 | ★★★★★ | Adds a teamwide Lunar-Charged DMG bonus based on Ineffa's ATK. |
| C2 | ★★★★★ | Adds a strong Lunar-Charged attack and lets the Burst create shields. |
| C3 | ★★★☆☆ | Raises Skill level by 3 for more damage and shield strength. |
| C4 | ★★★★☆ | Restores 5 Energy when the team triggers Lunar-Charged. |
| C5 | ★★★☆☆ | Raises Burst level by 3. |
| C6 | ★★★★★ | Adds frequent extra Lunar-Charged attacks to increase personal damage. |
Constellation Effects
- C1 — Rectifying Processor: Creating Ineffa's shield grants the team Lunar-Charged DMG based on her ATK, reaching 50% at 2,000 ATK.
- C2 — Support Cleaning Module: Her Burst applies a mark that triggers an AoE attack dealing 300% of Ineffa's ATK as Lunar-Charged DMG. It also allows the Burst to create shields for nearby party members.
- C3 — Enhanced Emotion Emulator: Increases Cleaning Mode: Carrier Frequency by 3 levels.
- C4 — The Edictless Path: Teamwide Lunar-Charged triggers restore 5 Energy to Ineffa, once every 4 seconds. This is most valuable when she is the team's only Electro character.
- C5 — Mirror's Dream Transcension: Increases Supreme Instruction: Cyclonic Exterminator by 3 levels.
- C6 — A Dawning Morn for You: While C1's buff is active, Ineffa launches an additional attack after nearby thunderclouds trigger, dealing 135% of her ATK as Lunar-Charged DMG. The effect can activate once every 3.5 seconds and represents her biggest personal-damage upgrade.
Conclusion
Ineffa build is a flexible off-field Sub-DPS in Genshin Impact who combines serious personal damage with a durable shield and consistent Electro application for Lunar-Charged teams. Her best results come from teams that can maintain Hydro application and take advantage of her ATK-based Lunar-Charged bonuses. So, it's time for action. Top up Genshin Impact with BuffBuff and max out Ineffa capabilities with the best team compositions.
