Ineffa is a 5-Star Electro Polearm sub-DPS and shielder built around Lunar-Charged reactions in Genshin Impact. Most of her work happens from off-field. She summons Birgitta to keep dealing Electro damage, creates a long-lasting shield, converts Electro-Charged into Lunar-Charged, and gives Elemental Mastery to herself and the active character.
Her kit also scales heavily with ATK. More ATK improves the shield, raises the Elemental Mastery buff from her Burst, and increases Lunar-Charged Base DMG through Moonsign Benediction: Assemblage Hub. That makes her easier to build than she first looks: stack enough ATK, balance CRIT and Energy Recharge, then let Birgitta keep working while your main DPS takes the field.
Current build references also classify her mainly as an off-field Electro sub-DPS with shielding and Lunar-Charged utility, which matches the mechanics in the supplied kit. If you are also planning Primogems around upcoming characters and reruns, check the current and upcoming Genshin Impact banner schedule.
Who is Ineffa and What is Their Playstyle?
Ineffa is not designed to stay on field and spam Normal Attacks. Her normal rotation is much simpler: cast Cleaning Mode: Carrier Frequency, summon Birgitta, create the Optical Flow Shield Barrier, use her Burst when needed, then swap back to your main carry.
Birgitta stays on the battlefield for 20 seconds and automatically moves near enemies before using Discharge attacks every two seconds. This gives the team steady off-field Electro application without taking field time away from characters such as Neuvillette or Varesa.
The shield is another major part of her value. At Talent Level 10, Optical Flow Shield Barrier absorbs damage equal to 398.1% of ATK + 3,051 and lasts 20 seconds. It also absorbs Electro DMG with 250% effectiveness. Because both Birgitta and the shield have long durations, this robot fits naturally into rotations that want a low-maintenance support.
Why is ATK so important for Ineffa?
ATK affects several parts of the build at the same time. Her shield directly scales from ATK. After using Supreme Instruction: Cyclonic Exterminator, the passive Panoramic Permutation Protocol also increases both Ineffa's and the current active character's Elemental Mastery by 6% of her ATK for 20 seconds. The Lunar-Charged passive adds another reason to build it. For every 100 ATK, Lunar-Charged Base DMG increases by 0.7%, up to a maximum increase of 14%.
In practical terms, ATK improves her shield strength, Elemental Mastery support, Lunar-Charged Base DMG, and the damage of her Skill, Burst, and Birgitta.
This is why current build recommendations favor ATK% main stats over pure EM for standard Lunar-Charged teams.
How does Ineffa enable Lunar-Charged?
Her passive Moonsign Benediction: Assemblage Hub changes Electro-Charged reactions triggered by the party into Lunar-Charged reactions.
It also raises the party's Moonsign by one level.
That conversion is central to her team value. She needs Hydro and Electro interaction to access the reaction, so a strong Hydro applier or Hydro main DPS is usually one of the most important partners.
This is also why she works especially well as a plug-in sub-DPS for characters that can keep Hydro application active while Birgitta handles Electro from off-field. For a direct Lunar-Charged carry that benefits from this kind of off-field support, see the Flins build guide. Players comparing other Lunar reaction archetypes can also use the Linnea build guide as a separate Lunar-Crystallize reference.
How Do Ineffa's Skills Work?
Normal Attack: Cyclonic Duster
Cyclonic Duster performs up to four consecutive spear attacks. The Normal Attack talent exists, but it is not a major part of her recommended support/sub-DPS rotation.
At Talent Level 10:
| Attack | Multiplier |
|---|---|
| 1st Hit | 68.9% |
| 2nd Hit | 67.6% |
| 3rd Hit | 45% + 45% |
| 4th Hit | 110.8% |
| Charged Attack | 187.7% |
| Plunge | 126.4% |
| Low / High Plunge | 252.7% / 315.6% |
The Charged Attack costs 25 Stamina. In a standard build, however, these values matter far less than Skill uptime, Birgitta, and Lunar-Charged damage.
Elemental Skill: Cleaning Mode: Carrier Frequency
This is the most important button in her normal rotation. Using the Skill deals one instance of AoE Electro DMG, creates the Optical Flow Shield Barrier, and summons Birgitta. At Talent Level 10:
| Skill Property | Value |
|---|---|
| Skill DMG | 155.5% |
| Shield Absorption | 398.1% ATK + 3,051 |
| Shield Duration | 20s |
| Birgitta Discharge DMG | 172.8% |
| Birgitta Duration | 20s |
| Skill CD | 16s |
The durations are especially useful. A 20-second shield and 20-second summon on a 16-second Skill cooldown give her plenty of room to fit into normal team rotations.
How does Birgitta work?
Birgitta is the real engine behind the off-field build. If enemies are nearby, she moves toward a target and releases a Discharge attack every two seconds, dealing AoE Electro DMG. Only one Birgitta summoned by Ineffa can exist at a time. The passive Overclocking Circuit adds another layer. If Lunar-Charged thunderclouds are nearby when Birgitta uses Discharge, she performs an additional attack dealing AoE Electro DMG equal to 65% of Ineffa's ATK.
That extra attack is counted as Lunar-Charged DMG, which is why keeping the reaction running is so important.
Elemental Burst: Supreme Instruction: Cyclonic Exterminator
Her Burst launches Birgitta into battle and deals a large instance of AoE Electro DMG. At Talent Level 10, the attack has a massive 1218.2% multiplier, costs 60 Energy, and has a 15-second cooldown. If Birgitta is already on the field, the Burst does not create a second copy. Instead, it moves her to the target location and resets her duration.
This lets you extend Birgitta's uptime across a longer rotation without recasting the Elemental Skill immediately.
The Burst also activates Panoramic Permutation Protocol, granting an Elemental Mastery buff for 20 seconds based on 6% of Ineffa's ATK.
What talent should you level first?
For a normal Lunar-Charged support/sub-DPS build, use: Elemental Skill > Elemental Burst >>> Normal Attack The Skill has the highest priority because it improves the shield and Birgitta's Discharge damage. Burst comes second. Normal Attack can safely stay low because this character normally leaves the field after setting up her abilities. Current 2026 build references recommend the same priority.
Best Ineffa rotation
The rotation is short, which is one of her biggest quality-of-life advantages.
- Use Cleaning Mode: Carrier Frequency to create the shield and summon Birgitta.
- Use Supreme Instruction: Cyclonic Exterminator when you want its damage, EM buff, and refreshed Birgitta duration.
- Set up Hydro application from your other characters.
- Swap to your main DPS or driver.
- Let Birgitta trigger off-field Electro and Lunar-Charged damage.
- Refresh Skill and Burst as the next rotation begins.
In teams where Burst uptime matters, use it before the main carry's damage window so the active character can benefit from Parameter Permutation for as much of that window as possible.
What is the Best Weapon for Ineffa?
Best-in-Slot: Fractured Halo
Fractured Halo is the signature weapon and the strongest direct fit for her kit. At Level 90, it provides: 608 Base ATK
66.2% CRIT DMG
At R1, using an Elemental Skill or Burst increases ATK by 24% for 20 seconds.
That alone is useful because ATK improves her damage, shield, EM buff, and Lunar-Charged scaling. The second half of the weapon is even more important: after creating a shield while the ATK effect is active, Electrifying Edict is gained for 20 seconds, causing all nearby party members to deal 40% more Lunar-Charged DMG.
Her Skill already creates a shield as part of the normal setup, so the signature weapon fits directly into the rotation without requiring an unusual combo.
Current build calculations also place Fractured Halo clearly above her alternative weapons because it boosts both personal stats and team Lunar-Charged damage.
Best 5-Star alternative: Staff of the Scarlet Sands
Staff of the Scarlet Sands is the strongest 5-Star alternative in the supplied data. At Level 90: 542 Base ATK
44.1% CRIT Rate
At R1, it converts 52% of Elemental Mastery into bonus ATK. When an Elemental Skill hits an opponent, it also grants bonus ATK equal to 28% of EM for 10 seconds, stacking up to three times.
This creates a useful ATK/EM loop. Gilded Dreams and Lunar-Charged teams can give her Elemental Mastery, while the weapon converts part of that EM back into ATK.
Current build comparisons also rank Staff of the Scarlet Sands as one of her strongest non-signature choices.
Best supplied 4-Star alternative: Ballad of the Fjords
Ballad of the Fjords provides 510 Base ATK and 27.6% CRIT Rate at Level 90.
When the party contains at least three different Elemental Types, R1 grants 120 Elemental Mastery.
That condition works naturally with many Lunar-Charged teams because they already combine Electro, Hydro, and a third support element such as Anemo or Geo.
The extra EM improves reaction damage, while the CRIT Rate helps Birgitta and her direct damage maintain a healthier CRIT ratio.
However, Ballad of the Fjords is not a true F2P weapon.
What is the best true F2P weapon?
For players who want a craftable option, current 2026 build references recommend Prospector's Shovel as her strongest true F2P fallback. It provides ATK and directly improves Electro-Charged and Lunar-Charged damage, making it a much more natural free option than forcing an unrelated Polearm.
| Weapon | Role | Why It Works |
|---|---|---|
| Fractured Halo | Best-in-Slot | ATK, CRIT DMG, and a powerful teamwide Lunar-Charged buff |
| Staff of the Scarlet Sands | 5-Star Alternative | High CRIT Rate and EM-to-ATK conversion |
| Ballad of the Fjords | 4-Star Alternative | CRIT Rate plus 120 EM in 3-element teams |
| Prospector's Shovel | F2P Option | Accessible ATK weapon with direct Lunar-Charged synergy |
Which Gear and Stats Maximize Ineffa's Damage?
Recommended Artifact Set: Gilded Dreams
Based on the supplied build data, 4-Piece Gilded Dreams is the recommended artifact set. The 2-piece bonus gives: Elemental Mastery +80
After triggering an Elemental Reaction, the 4-piece set gives bonuses based on the elements of the other three party members. For each teammate who shares the wearer's element, ATK increases by 14%. For each teammate with a different element, Elemental Mastery increases by 50.
Up to three teammates can contribute to these bonuses, and the effect can trigger once every eight seconds. More importantly, Gilded Dreams can activate while the wearer is off-field, which suits Birgitta perfectly.
The exact bonus changes with the team. For example, in Neuvillette + Ineffa + Xilonen + Furina, all three teammates use elements different from Electro, allowing Gilded Dreams to lean heavily into Elemental Mastery. In the Varesa lineup, the second Electro character adds an ATK bonus while Hydro and Anemo add EM.
What main stats should Ineffa use?
For a standard Lunar-Charged build, current build references recommend prioritizing ATK over pure EM because ATK improves more parts of the kit at once.
| Artifact Slot | Recommended Main Stat |
|---|---|
| Sands | ATK% |
| Goblet | ATK% |
| Circlet | CRIT Rate / CRIT DMG |
A normal Electro DMG Goblet is not the default choice for this setup. Her most important value comes from Lunar-Charged, Birgitta, shielding, and ATK-based utility rather than simply stacking Electro DMG Bonus. Current build analysis specifically favors ATK% on both Sands and Goblet.
Best substats
Use this priority as a practical rule:
Energy Recharge to requirement > CRIT Rate / CRIT DMG > ATK% > Elemental Mastery
Do not read this as “ER is always the best stat.” It only needs to reach the point where your chosen rotation works.
Current build recommendations suggest roughly 140–150% ER as a comfortable reference point when a second Electro character is helping with Energy. Solo-Electro teams can need more, and it is also possible to build less ER and use the Burst every other rotation instead.
What Are the Best Team Comps for Ineffa?
The best Ineffa teams need a reliable source of Hydro because her defining passive converts Electro-Charged into Lunar-Charged. Birgitta handles Electro application from off-field, so the active character can focus on driving reactions or dealing their own damage.
Team 1: Neuvillette + Ineffa + Xilonen + Furina
This is a strong premium setup built around Neuvillette as the on-field Hydro DPS.
He supplies frequent Hydro application while Birgitta supplies Electro from off-field. That interaction keeps Lunar-Charged available without forcing Ineffa to take field time. Furina adds more off-field Hydro and a major team damage buff, while Xilonen brings resistance reduction and healing support. Current guides specifically list the Neuvillette + Ineffa + Furina + Xilonen combination as a functional premium team.
Ineffa's job here is simple: create the shield, summon Birgitta, use Burst when needed, then get out of the way. Neuvillette receives the long field window.
A practical flow is:
Furina setup → Xilonen setup → Ineffa Skill/Burst → Neuvillette damage window
This keeps Hydro active, gives Birgitta plenty of time to attack, and places the Lunar-Charged engine behind the main carry rather than interrupting him.
Team 2: Varesa + Ineffa + Xianyun + Furina
This lineup combines Lunar-Charged with Varesa's Plunging Attack playstyle.
Varesa takes the on-field DPS role. Furina provides Hydro application and team damage buffs, creating the Hydro side needed for Ineffa's Lunar-Charged conversion. Xianyun supports Plunging Attack damage while also providing healing, which helps Furina build her teamwide buff.
Ineffa stays off-field with Birgitta and supplies the shield, Electro presence, and Lunar-Charged conversion. Current team references specifically list Varesa + Furina + Ineffa + Xianyun as a viable Varesa team.
The main advantage is role separation: Varesa handles the active damage window, Xianyun enables the plunge side of the team, Furina handles Hydro and buffs, while the robot keeps adding reaction damage without stealing field time.
For a more accessible reaction team, the supplied Sucrose + Ineffa + Xingqiu + Fischl lineup also works. Sucrose can drive reactions and provide EM support, Xingqiu supplies Hydro, and Fischl adds more off-field Electro. Current team databases also list this exact four-character core as an Ineffa Lunar-Charged option.

Which Constellations (Awakenings) Are Worth Getting?
| Level | Effect | Value / Verdict |
|---|---|---|
| C1 – Rectifying Processor | Activating Optical Flow Shield Barrier gives nearby party members Carrier Flow Composite for 20s. Lunar-Charged DMG increases by 2.5% per 100 ATK, up to 50%. | Excellent support breakpoint. The buff affects nearby party members and directly improves the team's core reaction. |
| C2 – Support Cleaning Module | Burst applies Punishment Edict. After a delay or when the target is defeated, nearby enemies take 300% ATK AoE Electro DMG counted as Lunar-Charged. Casting Burst also gives nearby party members Optical Flow Shield Barriers. | Strong second stopping point. Adds Lunar-Charged damage and makes Burst much better for team protection. |
| C3 – Enhanced Emotion Emulator | Cleaning Mode: Carrier Frequency Level +3. | Useful but not a priority. Improves the Skill, including a talent you already level first. |
| C4 – The Edictless Path | Party Lunar-Charged reactions restore 5 Energy, once every 4s. | Good rotation upgrade. Reduces Energy pressure in reaction-heavy teams. |
| C5 – Mirror's Dream Transcension | Supreme Instruction: Cyclonic Exterminator Level +3. | Moderate. Raises Burst damage but does not change the basic role. |
| C6 – A Dawning Morn for You | While Carrier Flow Composite is active, nearby thundercloud lightning causes an extra attack dealing 135% ATK AoE Electro DMG, counted as Lunar-Charged. Can trigger once every 3.5s. | Major personal damage upgrade. Best for high-investment Lunar-Charged teams. |
What is the best constellation stopping point?
C1 is the best early stopping point for most Lunar-Charged teams.
At the maximum condition, Carrier Flow Composite provides up to 50% Lunar-Charged DMG, so the constellation has team value rather than only improving Ineffa's personal numbers.
If you want to invest further, C2 is the next sensible stopping point. It adds a 300% ATK Lunar-Charged attack and lets her Burst distribute Optical Flow Shield Barriers to nearby party members.
Current 2026 build analysis reaches a similar conclusion: C1 is the most useful early constellation, while C2 is the next practical stopping point unless you plan to push all the way toward C6. It also rates the signature weapon very highly as an investment because Fractured Halo adds a large teamwide Lunar-Charged buff.
Is Ineffa Worth Pulling?
Yes, if your account wants a Lunar-Charged off-field unit, shield, and Electro application in one slot. Her biggest strength is role compression. One character can provide a 20-second shield, long-lasting off-field Electro through Birgitta, Lunar-Charged conversion, an active-character EM buff, and meaningful personal reaction damage. She is particularly attractive if you already use Hydro-heavy carries or plan to build dedicated Lunar-Charged teams. Neuvillette can keep Hydro active while Birgitta works from off-field, while Varesa teams can use Furina to enable the reaction without disrupting the plunge-focused damage window.
Her weaknesses are just as clear. She is much less exciting when the team does not consistently trigger Electro-Charged/Lunar-Charged, because a large part of the kit is built around that reaction. Current build analysis likewise notes that her personal damage drops sharply without reliable Hydro application.
Pull Ineffa if you want a strong off-field Electro sub-DPS, a 20-second ATK-scaling shield, a dedicated Lunar-Charged enabler, a unit that supports a main DPS without stealing field time, and a character that combines sustain, reactions, and personal damage.
You may want to skip if you are not interested in Lunar-Charged teams, rarely use Hydro partners, or already have enough off-field Electro and defensive options for the teams you play. If you are saving instead, compare the Genshin Impact 7.0 banner with the Genshin Impact 7.1 banner before committing your next guarantee.
At C0, her full core kit already works. For extra investment, C1 is the most attractive early constellation, C2 adds more damage and defensive utility, while Fractured Halo is the premium weapon choice for players who want to maximize both her own build and the team's Lunar-Charged output. If you decide to spend for constellations or Fractured Halo, review the available Genshin Impact top-up options before purchasing Genesis Crystals.
Frequently Asked Questions (FAQ)
Q: Does Ineffa need a lot of Energy Recharge?
A: It depends on how often you want to use Supreme Instruction: Cyclonic Exterminator. In teams with another Electro unit, around 140–150% ER is a useful current reference point for Bursting every rotation. Solo-Electro setups can need more. You can also run less ER and use the Burst every other rotation if the team does not rely heavily on its Elemental Mastery buff. Do not sacrifice all your ATK and CRIT just to hit one fixed ER number. Build enough Energy Recharge for the rotation you actually use.
Q: Should Ineffa use an ATK Goblet or Electro DMG Goblet?
A: For the standard Lunar-Charged build, use an ATK% Goblet. ATK improves her shield, Elemental Mastery buff, Lunar-Charged Base DMG scaling, and direct talent damage. A normal Electro DMG Goblet does not cover all of those parts of the kit, which is why current build recommendations favor ATK%.
Q: Is Ineffa a main DPS or sub-DPS?
A: She is primarily an off-field sub-DPS, shielder, and Lunar-Charged enabler. The standard gameplay is to cast Skill and Burst, summon Birgitta, then swap to another character. Birgitta continues attacking every two seconds while the active carry handles the main field time. That low field-time requirement is one of the biggest reasons she fits so well beside characters such as Neuvillette and other reaction-focused carries.
