Iuno is a 5-star Aero Gauntlet Resonator in Wuthering Waves. She operates best as a Sub-DPS that can buff characters that deal most of their damage through their Heavy Attacks such as Zani, Augusta, Jiyan, and Calcharo.
Iuno requires a proper build with the best Echoes, weapons, and stats to truly make her viable. Here is a quick rundown on how to build Iuno in Wuwa.
Iuno Best Echoes in Wuwa

Iuno’s Best Echo set in Wuthering Waves is Crown of Valor. The 3-piece bonus this set provides is perfect for Iuno’s kit as it provides a lot of free ATK% and CRIT DMG.
Pairing this with a 2-pc Sierra Gale, Gusts of Welkin, or Windward Pilgrimage will help Iuno deal just that little bit more Aero DMG.
For the Main Echo slot, Lady of the Sea is the best choice as it provides bonus Aero and Resonance Liberation DMG.
Iuno Echo stats, substats and Forte priority in Wuwa
Iuno’s recommended Echo stats and substats in Wuthering Waves are straightforward and easy to obtain. Focus on getting the follow stats for Iuno’s Echoes:
- 4-cost Echo: CRIT Rate/DMG
- 3-cost Echoes: Aero DMG Bonus
- 1-cost Echoes: ATK%
Substat priority: CRIT Rate/DMG > ATK% > Resonance Liberation DMG > ATK
As for her Forte priority, the following order is the most optimal:
Forte Circuit > Resonance Liberation > Resonance Skill = Normal Attack > Intro Skill
Iuno Best Weapons in Wuthering Waves

Here are some of Iuno’s best weapons in Wuwa:
- Moongazer’s Sigil (Signature)
- Blazing Justice
- Verity’s Handle
- Abyss Surges
- Aether Strike
- Stonard
- Hollow Mirage
Moongazer’s Sigil is Iuno’s best weapon which doesn’t come as a surprise as it is her signature. However, Abyss Surges is a solid F2P 5-star weapon that can be used as an alternative.
For 4-star options, the new Battle Pass weapon, Aether Strike is a very good choice. Hollow Mirage is also a decent 4-star weapon that provides a fair bit of ATK% for Iuno.
