With the launch of Genshin Impact 5.8, a powerful new 5-star character, Inefe, has entered the spotlight. She introduces a fresh reaction system called Electro-Charged Moonlight (“Yuegan Dian”) and takes the role of a backline Sub-DPS with support and survival utility.
In this guide, we’ll dive into everything you need to know to build Inefe correctly, from artifact recommendations to team comps, weapon choices, and how to fully unleash the power of this new reaction-focused system.
Inefe Overview: A Versatile Backline Sub-DPS
Inefe is a Moonlight Electro-Charged (MEC) support character who provides sustained damage, shielding, and party-wide utility. Unlike characters like Fischl or Faruzan, Inefe doesn’t force strict mono-elemental teams. She only requires Hydro and Electro characters to trigger MEC, while the rest of the team can include Anemo, Geo, or others.
In low-investment teams, she offers a DPS boost of around 25,000, making her one of the most impactful supports for underused or outdated team comps. She effectively revives forgotten characters and brings them back into the meta.

Understanding the Moonlight Electro-Charged Mechanism (MEC)
Key Mechanics:
- MEC is a transformation reaction, meaning it ignores enemy defense;
- It is not affected by Damage Bonuses, but it does benefit from enemy RES reduction;
- MEC scales with ATK, Elemental Mastery (EM), CRIT stats, and resistance shred.
Pro tip: Aim for around 400 EM. Beyond that, returns begin to diminish, so prioritize CRIT and ATK for further gains.
Damage Sources:
MEC has two components:
- Reactive MEC: Damage from elemental reactions (Electro + Hydro);
- Direct MEC: Flat damage tied to Inefe’s passive talents.
MEC Reactive Damage Formula:
Top DPS in Team × 100%
+ Second DPS × 50%
+ Third DPS × 8.3%
+ Fourth DPS × 8.3%
= Total MEC Reactive Damage
Only characters involved in the reaction contribute to this formula. For example, pure Geo units are excluded, while Anemo units like Kazuha can contribute if they swirl Hydro or Electro.
To ensure consistent MEC damage, CRIT rate balance is crucial across contributing characters. Focus on your main DPS and Inefe, as they provide the bulk of the damage.
Best Weapons for Inefe
Inefe benefits from CRIT, ATK%, and EM, so weapon selection should cover at least two of these. Here are top options:
- Top Choice: Her signature weapon (best-in-slot across all builds);
- Strong Alternatives:
- Staff of the Scarlet Sands – ideal for EM-heavy builds;
- Song of Stillness – balanced stats, great synergy;
- Budget Options:
- The Catch, F2P-friendly Polearms like Deathmatch or Missive Windspear;
- Fjord’s Song, Dragon’s Bane (if available through monthly shop or events).
Recommended Artifacts
Main Set Recommendation:
- Gilded Dreams (4-piece) – Best synergy with EM + reaction playstyle.
Viable Alternatives:
- 2-piece EM + 2-piece ATK
- 2-piece EM + 2-piece CRIT
- Tenacity of the Millelith (4-piece) – for team support when paired with ATK-scaling characters
Not Recommended:
- Thundering Fury – The 2-piece Electro DMG Bonus doesn’t apply to MEC, as transformation reactions ignore damage bonuses.
Artifact Stats Priority:
- Main Stats:
- Sands: ATK% or EM (depends on weapon)
- Goblet: ATK%
- Circlet: CRIT Rate or CRIT DMG
- Sub-stats Priority:
- CRIT Rate / CRIT DMG > ATK% > EM > Energy Recharge
Talent Priority
- Skill (Elemental Skill): Highest priority, worth crowning
- Burst (Elemental Burst): Optional but useful
- Normal Attack: Can be ignored completely
Constellation & Signature Weapon: Is It Worth It?
C0 Inefe already enables the MEC system fully.
- C1 offers a ~10% damage increase
- C2 adds ~200k+ burst damage and slight survivability
Her signature polearm also boosts her overall performance by roughly 10%. If you’re considering spending an extra pull, either C1 or her weapon are solid, but not essential.
Best Team Comps for Inefe
Cyno MEC Team
Inefe + Cyno + Xingqiu + Nahida
Cyno benefits from EM scaling and sustained uptime, while Nahida enables Quicken/Hyperbloom. Xingqiu strengthens the shield and adds Hydro application.

Dragonlord Variant
Inefe + Neuvillette + Furina + Kazuha
Kazuha’s Swirl can participate in MEC damage if infused with Hydro/Electro. Neuvillette provides front-loaded AoE damage while Furina boosts team-wide buffs.

MEC Midrange Core
Inefe + Ifa + Xingqiu + Olorun
Ifa’s aerial EM scaling + Olorun’s Night Soul mechanics synergize well. The result: 30%+ increased MEC damage output.

Upgraded Electro-Charged Core
Inefe + Sucrose + Xingqiu + Fischl
A classic Electro-Charged comp, now with stronger survivability and consistent backline damage.
The general formula is Electro + Electro + Hydro + Flex (Anemo/Geo). There’s room to experiment with many units.
Final Thoughts
Inefe introduces an exciting new reaction-based system into Genshin Impact’s 5.8 meta. As a Sub-DPS built around transformation reactions, she delivers consistent off-field value, protection, and scalability—especially for free-to-play and low-resource teams.
While the MEC system still lacks a premier front-line enabler, Inefe herself is a solid foundation for teams that blend Hydro, Electro, and a flexible fourth slot.
