Iuno Build Guide: Best Weapons, Echoes, Teams & More | Wuthering Waves

Iuno is a 5-star Aero Gauntlets Resonator who combines personal damage, healing, team buffs, and Heavy Attack support. She is primarily played as a hybrid support and sub-DPS, although players with stronger equipment can also build her as a Main DPS.

Iuno Build Overview

Iuno is most valuable when supporting a character who deals substantial Heavy Attack damage. Her Outro Skill grants the incoming Resonator 50% Heavy Attack DMG Amplification, while her Full Moon Domain provides healing, Stamina recovery, and stacking All DMG Amplification.

How Iuno's Kit Works

Iuno enters Lunar Cycle through her Resonance Skill or Resonance Liberation. Lunar Cycle has two states: Half Moon and New Moon.

In Half Moon, Iuno attacks with the Moonring and restores Sentience. She can then use Heavy Attack: Flux to enter New Moon, where her Moonbow attacks and Resonance Skills consume Sentience for more damage, Concerto Energy, and team healing.

Once her Concerto Energy is full, Iuno can cast Heavy Attack: Absolute Fullness. This ends Lunar Cycle, heals the team, deals Aero DMG, and creates the Full Moon Domain.

Characters inside the domain recover HP and Stamina. Gaining a Shield inside the domain also grants Blessing of the Wan Light, providing up to 40% All DMG Amplification at maximum stacks.

Hybrid Support or Main DPS?

Use Iuno as a hybrid support when the team includes a dedicated Heavy Attack DPS such as Jingran or Augusta. This route gives Iuno moderate field time before she passes her Outro buff to the carry.

Main DPS Iuno stays active longer and focuses on Moonbow and Resonance Liberation damage. This playstyle is viable, but it benefits more from her signature weapon, premium teammates, and high-quality Echoes.

Iuno Skill Priority

Iuno's upgrade order changes slightly according to her role.

For hybrid support:

Forte Circuit > Resonance Liberation > Intro Skill > Resonance Skill >Basic Attack

For Main DPS:

Forte Circuit > Resonance Liberation > Basic Attack > Resonance Skill > Intro Skill

Forte Circuit is always the first priority because it controls Iuno's Lunar Cycle, Sentience use, enhanced attacks, healing, and Full Moon Domain.

Resonance Liberation comes next because it activates Lunar Cycle, restores Sentience, and contributes a substantial portion of her personal damage. After that, hybrid builds favor Intro Skill, while Main DPS builds gain more from Basic Attack.

Best Weapons for Iuno

Weapon	Recommendation	Why It Works
Moongazer's Sigil	Best overall	Provides CRIT Rate, ATK, Liberation DMG, and DEF Ignore
Verity's Handle	Strong alternative	Offers CRIT Rate and a large Liberation DMG Bonus
Blazing Justice	General 5-star option	Supplies CRIT DMG, ATK, and partial DEF Ignore
Abyss Surges	Standard 5-star option	Provides high Base ATK and ATK%, despite a less suitable passive
Legend of Drunken Hero	Craftable option	Requires no Convene pulls and provides useful ATK

Moongazer's Sigil is Iuno's strongest weapon for both hybrid and Main DPS builds. Its Shield-triggered effect is easy for her to maintain because her Inherent Skill repeatedly creates personal Shields.

The signature weapon mainly improves Iuno's own damage. Her healing, Full Moon Domain, and Heavy Attack Outro buff still function without it, making alternative weapons sufficient when she is used primarily as a support.

Verity's Handle is the strongest general alternative. Players without a limited weapon can use Abyss Surges, while Legend of Drunken Hero is the most accessible craftable option.

Best Echoes for Iuno

Crown of Valor Damage Build

Iuno's recommended personal-damage setup is:

• 3-Pc Crown of Valor
• 2-Pc Aero DMG set
• Lady of the Sea as the main Echo
• 4-3-3-1-1 Echo cost

Crown of Valor increases ATK and CRIT DMG whenever Iuno gains a Shield. Her Inherent Skill allows her to build the set's stacks without relying on another shielder.

For the remaining two pieces, use Sierra Gale or another set providing a 2-piece Aero DMG Bonus.

Lady of the Sea is the preferred main Echo because it provides both Aero DMG Bonus and Resonance Liberation DMG Bonus without adding a restrictive activation condition.

Moonlit Clouds Support Build

Use 5-Pc Moonlit Clouds when Iuno's main purpose is to strengthen another damage dealer.

Moonlit Clouds provides Energy Regen and increases the ATK of the next Resonator after Iuno uses her Outro Skill. Pair it with Impermanence Heron for additional Resonance Energy and another buff for the incoming character.

This setup reduces Iuno's personal damage but increases the value of her support rotation.

Iuno Echo Main Stats

Choose the 4-Cost CRIT stat according to Iuno's weapon and existing substats.

Hybrid Iuno generally wants around 120% to 130% Energy Regen. Main DPS teams with stronger Energy generation may function with less.

Iuno Substat Priority

Prioritize:

1. Energy Regen until the rotation is consistent
2. CRIT Rate and CRIT DMG
3. Resonance Liberation DMG Bonus
4. ATK%
5. Flat ATK

Once Iuno can use her Resonance Liberation every rotation, prioritize offensive substats instead of continuing to stack Energy Regen.

Iuno Best Teams

Jingran, Iuno, and Shorekeeper

Jingran

Iuno

Shorekeeper

Jingran benefits directly from Iuno's Heavy Attack DMG Amplification. His Shield mechanics also work well with her Full Moon Domain, allowing him to build Blessing of the Wan Light while dealing damage.

Shorekeeper completes the team with healing, CRIT buffs, and general damage support. Use Iuno immediately before Jingran so her Outro reaches the correct character.

Augusta, Iuno, and Shorekeeper

Augusta

Iuno

Shorekeeper

Augusta is another natural partner because Heavy Attacks account for a large part of her damage. Iuno contributes damage and healing before transferring her Outro buff to Augusta.

Verina can replace Shorekeeper when Shorekeeper is needed by another team.

Iuno, Lynae, and Mornye

Iuno

Lynae

Mornye

This premium team builds around Main DPS Iuno. Lynae supplies strong general and Resonance Liberation-focused buffs, while Mornye provides further support and sustain.

Because Iuno spends more time on the field, her signature weapon and Crown of Valor Echo quality have a greater effect on the team's performance.

Iuno, Ciaccona, and Shorekeeper

Iuno

Ciaccona

Shorekeeper

Ciaccona supports Iuno's Aero damage while contributing personal damage through a relatively short rotation. Shorekeeper supplies healing and teamwide buffs.

This is a strong alternative for players who want Iuno to lead the team but do not have Lynae and Mornye available.

Iuno, Jianxin, and Verina

Iuno

Jianxin

Verina

This is a more accessible Main DPS team using standard 5-star characters. Jianxin strengthens Iuno's Resonance Liberation damage, while Verina provides healing and ATK buffs.

Its damage ceiling is lower than Iuno's premium teams, but it is suitable for players building around characters already available on their account.

Iuno Resonance Chain

Iuno is fully functional at S0, so additional copies are not required for her Heavy Attack buff, healing, or Full Moon Domain.

Important Resonance Chain levels include:

• S1: Increases Iuno's ATK during Lunar Cycle, improves Energy recovery, and adds interruption resistance to important actions.
• S2: Adds another large All DMG Amplification effect for characters reaching maximum Blessing stacks.
• S3: Significantly increases the damage of Iuno's Moonbow attacks and Arc Beyond the Edge.
• S4: Adds a team Shield after Absolute Fullness, improving comfort and Full Moon Domain synergy.
• S6: Greatly strengthens Absolute Fullness and extends Iuno's personal damage rotation.

Most players should remain at S0. S2 is the primary stopping point for players investing in Iuno's support value, while S3 and S6 are more relevant to damage-focused builds.

Is Iuno Worth Pulling?

Iuno is worth considering if you use Jingran, Augusta, Jiyan, or another character who benefits from Heavy Attack amplification. She offers personal damage, healing, Stamina recovery, and specialized offensive support in a single team slot.

She is less important for accounts without a suitable Heavy Attack DPS. Main DPS Iuno is viable, but reaching her strongest performance requires more investment than using her as a hybrid support.

Iuno FAQ

Conclusion

Iuno is a flexible hybrid who can support Heavy Attack carries or become the team's main damage dealer with greater investment. Choose her role according to your roster rather than trying to combine both playstyles in every team.
