Ineffa Build Guide 2026 | Best Artifacts, Weapons & Teams

Who Is Ineffa?

Ineffa is a limited 5-star Electro Polearm character from Snezhnaya, released in Version 5.8 (July 30, 2025). She is a sub-DPS/support who transforms standard Electro-Charged reactions into the unique Lunar-Charged variant. Her constellation is Arbor Umbra, and details about her background remain mysterious.

Ineffa's core mechanic revolves around the Lunar-Charged reaction, a special variant of Electro-Charged that combines attributes from all contributing characters. She provides consistent off-field Electro application through her assistant Birgitta, shields based on ATK, and Elemental Mastery buffs for the team. Her kit scales with ATK, making her straightforward to build.

When enemies have both Electro and Hydro aura, Lunar-Charged triggers instead of standard Electro-Charged.
Damage calculation considers attributes from all contributing characters (EM, Crit, reaction DMG bonus).
First contributor counts at 100%, second at 50%, subsequent at reduced values.
Reaction damage can crit and ticks every 2 seconds.
