Iuno is a 5-star Aero Gauntlets Resonator in Wuthering Waves, first released in Version 2.6. She can work as a damage-focused hybrid support or take the main DPS slot herself. Her kit combines Resonance Liberation DMG, healing, Shield generation, and a 50% Heavy Attack DMG Amplification Outro, giving her two very different ways to contribute to a team.
With Jingran, Iuno focuses on setting up Full Moon Domain and passing her Heavy Attack buff to him. In a Lynae and Mornye team, she becomes the main damage dealer, taking advantage of their Liberation-focused buffs to strengthen her own attacks. The weapon and Echo choices overlap, but how much you invest in Iuno's personal damage should depend on which role you want her to play.
How Iuno Works: Lunar Cycle, Sentience, and Full Moon Domain
Iuno's combat revolves around Lunar Cycle, which has two states: Half Moon and New Moon. Activating Closing Refrain or Resonance Liberation puts her into Half Moon by default. During Lunar Cycle, pressing Jump performs Heavy Attack - Flux, allowing her to change moon phases. Holding Jump instead ends Lunar Cycle, so the two inputs serve different purposes.
In Half Moon, her Moonring attacks restore Sentience, the resource that powers up her next set of attacks. Switching to New Moon changes her weapon to Moonbow and gives her access to Arc Beyond the Edge, a mobile Resonance Skill with two initial charges. Moonbow attacks and Arc Beyond the Edge consume Sentience to increase their damage, generate extra Concerto Energy, and heal nearby teammates.
Although Moonbow uses Basic Attack inputs, its damage is classified as Resonance Liberation DMG. The same classification applies to Arc Beyond the Edge and Absolute Fullness. This distinction explains why Liberation-focused weapons and Echo stats are so relevant to Iuno's damage build.
Absolute Fullness and Blessing of the Wan Light
Once Iuno fills her Concerto Energy, holding Normal Attack casts Heavy Attack - Absolute Fullness. It deals Aero DMG, heals nearby teammates, ends Lunar Cycle, and creates a Full Moon Domain. The domain lasts 30 seconds, periodically restores HP and STA, and can be generated once every 25 seconds.
The domain's damage buff requires an additional condition: the active Resonator must gain a Shield while inside it. Each qualifying Shield grants one stack of Blessing of the Wan Light, with a maximum of one stack every 0.5 seconds. Each stack provides 4% All DMG Amplification, up to 40% at 10 stacks. Gaining another stack refreshes the 10-second duration, but switching the receiving Resonator off the field removes the effect.
This makes Shield-generating damage dealers especially compatible with Iuno. Jingran can repeatedly generate Shields during his own attacks, allowing him to build Blessing stacks without needing Iuno's personal Shield to transfer over. Her Waxing Ascent Shield only protects Iuno herself, while the Full Moon Domain rewards whichever active teammate can continue generating Shields.
Iuno also grants the next incoming Resonator 50% Heavy Attack DMG Amplification for 14 seconds through From Gloom to Gleam. The buff ends early if that character switches out. For Jingran teams, the goal is therefore to finish Iuno's setup with Absolute Fullness, trigger her Outro, and let Jingran spend his main damage window on the field.
Best Weapons for Iuno
Moongazer's Sigil is the strongest listed choice for Iuno's personal damage because its passive matches her Shield generation and Liberation-based attacks. Verity's Handle offers a similar damage focus without the signature weapon's DEF Ignore, while Aether Strike is a practical 4-star alternative. All three can support the same core rotation, although their Crit stats and passive effects change how you build her Echoes.
| Weapon | Lv. 90 Stats | R1 Effect | Best Use |
|---|---|---|---|
| Moongazer's Sigil (5★) | 500 ATK 36% Crit. Rate |
12% ATK, 20% Resonance Liberation DMG Bonus, and up to 36% DEF Ignore for Liberation DMG through Shield stacks. | Best personal damage option for hybrid and main DPS builds. |
| Verity's Handle (5★) | 588 ATK 24.3% Crit. Rate |
12% Attribute DMG Bonus and 48% Liberation DMG Bonus after using Resonance Liberation, extendable through Resonance Skills. | Strong 5-star alternative for a Liberation-focused rotation. |
| Aether Strike (4★) | 413 ATK 40.5% Crit. DMG |
After casting Resonance Liberation, gain 7.2% ATK and 10.8% Liberation DMG Bonus for 15 seconds. | Accessible lower-rarity damage option. |
Moongazer's Sigil: Strongest Personal Damage
Moongazer's Sigil provides 36% Crit. Rate at Level 90, reducing the amount of Crit. Rate Iuno needs from her Echoes. Its Plenilune Radiance passive grants 20% Resonance Liberation DMG Bonus for 15 seconds after an Intro Skill or Liberation, while gaining Shields allows her Liberation damage to ignore up to 36% of enemy DEF at maximum stacks.
Her Intro Skill immediately maximizes the weapon's DEF Ignore stacks for three seconds, and Waxing Ascent helps maintain them afterward through repeated Shield generation. The benefit covers her own Liberation-classified damage rather than strengthening her teammates directly. It is especially appealing when Iuno is one of the team's main damage contributors.
Verity's Handle and Aether Strike
Verity's Handle has a higher Base ATK than Moongazer's Sigil and grants a large Liberation DMG Bonus after Iuno casts her ultimate. Resonance Skill casts can extend that bonus, matching a New Moon rotation that uses Arc Beyond the Edge repeatedly. Its main limitation is that the Liberation-triggered buff does not help the initial Liberation hit in the same way as a preactivated passive, so its damage value depends partly on attack timing.
Aether Strike is a reasonable choice when neither 5-star Gauntlet is available. Its Crit. DMG secondary stat is helpful, and its passive activates naturally during a Liberation rotation. The lower Base ATK and smaller Liberation bonus limit its damage potential compared with the premium choices, but it still covers the relevant damage type.
Investment advice: If Iuno primarily supports Jingran, upgrading from an already-built alternative to Moongazer's Sigil is less urgent than it would be for a main DPS Iuno. Her Full Moon Domain and 50% Heavy Attack Amplification are part of her character kit, not her signature weapon. Spending additional pulls on her weapon mainly improves Iuno's own damage contribution.
Best Echo Sets and Stat Priorities
The choice between Crown of Valor and Moonlit Clouds depends on how much of the team's damage Iuno is expected to deal. Crown of Valor improves her personal output through Shield-triggered stats, while Moonlit Clouds trades some of that potential for an ATK buff to the incoming Resonator.
| Echo Setup | Effect and Main Echo | Recommended Role |
|---|---|---|
| 3-Piece Crown of Valor + 2-Piece Aero DMG Set | Crown of Valor grants up to 30% ATK and 20% Crit. DMG through Shield stacks. Pair with a 2-piece Aero set for 10% Aero DMG Bonus. Main Echo: Lady of the Sea. |
Main DPS Iuno and damage-oriented hybrid Iuno. |
| 5-Piece Moonlit Clouds | Provides 10% Energy Regen and grants the next incoming Resonator 22.5% ATK after Iuno uses Outro. Main Echo: Impermanence Heron. |
Jingran-focused support setup that emphasizes his damage. |
Crown of Valor: Personal Damage and Flexible Hybrid Builds
Iuno can reliably activate Crown of Valor because Waxing Ascent generates a Shield whenever she uses a Basic Attack, Heavy Attack, Dodge Counter, Resonance Skill, Resonance Liberation, or Intro Skill. Each qualifying Shield adds 6% ATK and 4% Crit. DMG for four seconds, stacking five times with a 0.5-second trigger interval. Her regular attack sequence supplies those triggers without requiring a separate Shield support.
For the remaining two Echo pieces, Sierra Gale, Gusts of Welkin, or Windward Pilgrimage can provide a 10% Aero DMG Bonus. Lady of the Sea is the preferred main Echo because its equipped bonus grants 12% Aero DMG and 12% Resonance Liberation DMG, both relevant to Iuno's attacks. This setup also fits a Jingran team if Iuno already has well-rolled Crown of Valor pieces and you want to retain her personal damage.
Moonlit Clouds: A More Jingran-Focused Setup
Moonlit Clouds becomes interesting when Jingran handles most of the team's damage. Its 22.5% ATK buff activates through Iuno's Outro, which is already how she passes her Heavy Attack Amplification to him. Impermanence Heron can add further outgoing support, although its animation requires more careful timing than Lady of the Sea.
Neither setup is automatically superior in every Jingran team. Crown of Valor preserves more of Iuno's personal damage, while Moonlit Clouds concentrates additional support on Jingran. His weapon, Resonance Chain investment, Iuno's existing Echo quality, and the team's actual rotation all influence the result. If your Crown of Valor pieces already have excellent Crit and Energy Regen rolls, rebuilding Moonlit Clouds from scratch is not automatically worthwhile.
Echo Main Stats and Energy Regen
Use the standard 4-3-3-1-1 Echo cost distribution. Iuno's healing and Shields scale with ATK, but a damage-oriented build usually gains more from balancing Crit, Aero DMG, and enough Energy Regen to use her Liberation consistently.
- 4-Cost: Crit. Rate or Crit. DMG, depending on her weapon and final Crit balance.
- 3-Cost: Aero DMG Bonus + Aero DMG Bonus, or Aero DMG Bonus + ATK% when the ATK piece has better substats.
- 1-Cost: ATK% on both pieces.
- Substats: Meet the rotation's Energy Regen needs first, then prioritize Crit. Rate, Crit. DMG, Resonance Liberation DMG Bonus, and ATK%.
For a well-developed hybrid build, roughly 65–80% Crit. Rate, 215–260% Crit. DMG, and 1,800–2,400 ATK are useful reference ranges rather than fixed requirements. Moongazer's Sigil makes Crit. Rate easier to obtain, while Aether Strike's Crit. DMG secondary stat may make a Crit. Rate main Echo more attractive.
Energy requirements vary more sharply with the team and rotation. Around 125–130% Energy Regen is a sensible starting point for a fast Jingran support rotation using Crown of Valor, while Moonlit Clouds supplies extra Energy Regen through its set bonus. Some main DPS rotations with Lynae and Mornye can operate with less. Check whether Iuno has enough Resonance Energy for her second rotation before trading additional Energy Regen rolls for damage.
Skill Upgrade Priority and Resonance Chain Investment
Iuno's Forte Circuit, Ebb and Flow, deserves the earliest investment because it controls the enhanced Moonbow attacks, Arc Beyond the Edge damage, healing, and Absolute Fullness. Resonance Liberation comes next for its large Aero damage multiplier and role in activating Lunar Cycle. Beyond those two, the upgrade order changes slightly depending on her role.
Main DPS: Forte Circuit > Resonance Liberation > Normal Attack > Resonance Skill > Intro Skill.
Jingran support / hybrid: Forte Circuit > Resonance Liberation > Intro Skill > Resonance Skill > Normal Attack.
Main DPS Iuno spends longer using Moonbow combos, making Normal Attack levels more relevant. A shorter hybrid rotation places greater emphasis on the Forte and Liberation before leaving the field. With limited upgrade materials, those first two abilities should receive attention before evenly leveling every skill.
Resonance Chains: Where Extra Investment Changes Her Role
Iuno's base kit already provides the Full Moon Domain and Heavy Attack Amplification needed for her Jingran team. Her Resonance Chains improve different parts of the kit rather than unlocking its basic support function.
- S1 – Wax or Wane, All Gild the Bough: Grants 40% ATK during Lunar Cycle, restores Resonance Energy while Iuno is inside Full Moon Domain, and adds interruption immunity to Arc Beyond the Edge and Absolute Fullness. Primarily improves personal output and reliability.
- S2 – Day or Night, Let This Be Eternal: Adds 40% All DMG Amplification for team members with 10 Blessing of the Wan Light stacks. Particularly relevant to Jingran because he can repeatedly generate Shields inside the domain.
- S3 – I Drink Deep of Their Forgetting: Amplifies Moonbow attacks, Arc Beyond the Edge, and Moonbow Dodge Counters by 65%, while allowing Arc Beyond the Edge to preserve the Moonbow attack sequence under its stated timing condition. More valuable for damage-focused play.
- S4 – Rainy Season Dwell in My Eyes: Casting Absolute Fullness grants all team members a Shield equal to 160% of Iuno's ATK for 30 seconds. This adds team protection and another Shield source.
- S5 – A Thousand Futile Glimpses: Grants Iuno 20% Resonance Liberation DMG Bonus.
- S6 – I Am the Constant in the Chaos: Increases the Absolute Fullness DMG Multiplier by 1600%, then returns Iuno to New Moon with 100 Sentience and refreshed Arc Beyond the Edge cooldowns. This substantially changes her damage sequence and field-time potential.
For a Jingran-focused account, S2 offers a particularly relevant team buff, provided Jingran can reach the required 10 stacks. For players building Iuno as the main DPS, S3 and S6 contribute more directly to her offensive gameplay. Neither path is required for her standard S0 rotation, so extra Resonance Chains should be treated as an investment choice rather than a prerequisite.
Best Iuno Teams and Combat Rotations
The following two teams use Iuno in different roles. Jingran wants her Heavy Attack Amplification and Full Moon Domain, while Lynae and Mornye are better suited to a rotation in which Iuno receives the final buffs and remains on the field to deal damage.
Team 1: Jingran + Iuno + Shorekeeper
Roles: Jingran (Main DPS) / Iuno (Hybrid Support and Sub-DPS) / Shorekeeper (Healer and Crit Support).
This is a strong match for Jingran's Heavy Attack mechanics. His main damage comes from Heavy Attack - Soul Raid and Heavy Attack - Stardome Meander, and he generates Shields through Earth Charm while attacking. Iuno's Outro directly amplifies those attacks, while her Full Moon Domain rewards Jingran for gaining Shields by building Blessing of the Wan Light.
Their Shield interaction has another benefit. Jingran's Trace the Vestige restores Ghost Shroud when nearby teammates gain Shields, even if those Shields are not transferable. Iuno generates Shields repeatedly during her own rotation, helping Jingran prepare Ghost Shroud before he takes the field. Shorekeeper adds healing, damage amplification, and Crit buffs through her upgraded Stellarealm.
Suggested rotation:
- Shorekeeper: Use her Skill and attacks to generate Concerto Energy, then cast Resonance Liberation to establish Outer Stellarealm. Use Outro to bring Iuno onto the field, upgrading Stellarealm through Iuno's Intro.
- Iuno: Start with Intro Skill, then use Closing Refrain and Lady of the Sea. Cast Beneath Lunar Tides to activate Lunar Cycle and follow with Jump to enter New Moon.
- Iuno's New Moon sequence: Use Moonbow Basic Attack 1–2, Arc Beyond the Edge, another Moonbow Basic Attack 1–2, and the second Arc Beyond the Edge. When Concerto Energy is full, hold Normal Attack for Absolute Fullness.
- Transfer to Jingran: Trigger Iuno's Outro during the Absolute Fullness finish, bringing Jingran in with 50% Heavy Attack DMG Amplification and upgrading Shorekeeper's Stellarealm again.
- Jingran: Use his Intro, prepare or spend Qi through his available attacks, and cast Burial of Thousand Souls to enter Yinghuo. Continue using Soul Raid and Stardome Meander while his damage buffs are active. His own Shield generation builds Blessing stacks inside Full Moon Domain.
Jingran's first enhanced Heavy Attack does not necessarily have all 10 Blessing stacks immediately. His repeated Shield triggers build them over the damage window, so later attacks can benefit from a larger amplification. Keep him within Full Moon Domain where practical and avoid unnecessary swaps during his 14-second Heavy Attack buff.
The sequence above is a practical rotation framework rather than a frame-perfect script. If Iuno lacks enough Concerto Energy for Absolute Fullness, add the necessary Moonbow hits before attempting the Heavy Attack. Likewise, Jingran's precise Qi sequence changes with his available resources and Resonance Chain level. The priority is preserving the transition from Iuno's Full Moon and Outro into Jingran's main damage window.
Team 2: Iuno + Lynae + Mornye
Roles: Iuno (Main DPS) / Lynae (Liberation Buffer and Sub-DPS) / Mornye (Healer and Team Buffer).
This composition gives Iuno more space to deal her own damage. Lynae's Let's Hit the Road! Outro grants the incoming Resonator 15% All DMG Amplification and 25% Resonance Liberation DMG Amplification for 14 seconds. Her Prismatic Overblast also increases the damage dealt by nearby team members by 24% for 30 seconds. Both effects complement Iuno's Liberation-classified attacks.
Mornye supports the team through healing, Off-Tune Buildup, and damage amplification. Her Outro grants 25% All DMG Amplification to the team for 30 seconds. Her Syntony Field boosts Off-Tune Buildup and resistance to interruption, while Observation Marker enables Interfered Marker when the required Tune Break condition is met. This creates an additional damage opportunity around successful Tune Breaks rather than an unconditional bonus against every target.
Suggested rotation:
- Mornye: Build Rest Mass Energy with Basic Attacks or available Skills, then use Geopotential Shift to enter Wide Field Observation Mode. If she enters through Intro Skill, she can access this mode directly. Establish Syntony Field, build Relative Momentum, and use Inversion to apply Observation Marker.
- Mornye's support finish: Use Distributed Array where available for healing and Concerto generation, and cast Critical Protocol while Syntony Field is active to create High Syntony Field. Trigger her Outro before moving to Lynae.
- Lynae: Use her Intro and Skill to build Overflow. With enough Overflow, hold Normal Attack for Spark Collision and enter Kaleidoscopic Parade. Perform three Polychrome Leaps to obtain True Color, then activate Visual Impact. Cast Prismatic Overblast within her setup and finish with Outro to transfer her Liberation DMG Amplification to Iuno.
- Iuno: Enter through Intro Skill, activate Lunar Cycle, and switch into New Moon. Use Moonbow attacks and Arc Beyond the Edge to consume Sentience and deal Liberation-classified damage. Cast Beneath Lunar Tides during her damage sequence, continue the available enhanced attacks, and use Absolute Fullness when Concerto Energy is ready.
Iuno's rotation here can include a longer Moonbow sequence than the quick Jingran support rotation. A practical extension is to use a three-hit Moonbow chain, Arc Beyond the Edge, Resonance Liberation, another Moonbow chain, and the next available Skill before finishing with Absolute Fullness. The exact number of Skill casts depends on cooldowns, existing charges, and whether a Tune Break can be worked into the sequence.
Lynae's Outro only benefits the incoming character until its duration expires or that character switches out. Avoid returning to Lynae or Mornye in the middle of Iuno's main damage window just to use an available minor ability. Mornye's longer team buff gives more flexibility, while Lynae's shorter incoming-character buff is the one to preserve around Iuno's strongest attacks.
These teams also call for different investment decisions. The Jingran composition benefits from Iuno's support kit even with a modest weapon and Echo setup. In the Lynae and Mornye composition, Crit quality, Liberation damage, and her signature weapon carry more weight because Iuno is responsible for the largest share of the team's direct damage.
Iuno Ascension and Skill Upgrade Materials
Raising Iuno from Level 1 to 90 requires Abyssal Husk, Sliverglow Bloom, Polygon Cores, and Shell Credits. Her skill upgrades use the Cadence material series and The Netherworld's Stare. Since Forte Circuit and Resonance Liberation have the greatest early value, players short on resources can focus on those upgrades before fully completing every talent.
| Material | Character Ascension Lv. 1–90 |
All Listed Skill Upgrades |
|---|---|---|
| Shell Credits | 170,000 | 2,030,000 |
| LF Polygon Core | 4 | 25 |
| MF Polygon Core | 12 | 28 |
| HF Polygon Core | 12 | 40 |
| FF Polygon Core | 4 | 57 |
| Abyssal Husk | 46 | — |
| Sliverglow Bloom | 60 | — |
| The Netherworld's Stare | — | 26 |
| Cadence Seed | — | 25 |
| Cadence Bud | — | 28 |
| Cadence Leaf | — | 55 |
| Cadence Blossom | — | 67 |
The combined Shell Credit cost for Level 90 ascension and the listed full skill upgrades is 2,200,000. This does not include leveling her weapon. If you are also preparing Moongazer's Sigil to Level 90, set aside another 330,000 Shell Credits, 6 LF Howler Cores, 6 MF Howler Cores, 10 HF Howler Cores, 12 FF Howler Cores, and the required Cadence materials.
For a new Iuno build, securing her ascension materials and enough resources for Forte Circuit and Resonance Liberation is more useful than immediately chasing perfect Echo substats. Once her main abilities are ready, improve Energy Regen consistency and Crit quality according to the team you actually use.

Iuno FAQ
Why does Jingran sometimes stop gaining Blessing of the Wan Light stacks during the second rotation?
Check whether Iuno created a new Full Moon Domain with Absolute Fullness. The previous domain lasts 30 seconds and does not remain active indefinitely. Without an active domain, Jingran's Shields no longer generate new Blessing stacks. Standing outside its effective area also prevents new stacks, and switching Jingran out clears the stacks he already received.
Does Iuno need S4 to help Jingran generate Full Moon buffs?
No. Jingran can generate Shields through his own Earth Charm, which allows him to accumulate Blessing stacks inside Full Moon Domain even when Iuno is S0. S4 adds a team-wide Shield when Iuno casts Absolute Fullness, giving the composition additional protection, but it is not needed for the basic Shield-to-Blessing interaction.
Should Lynae use Tune Rupture or Tune Strain in an Iuno and Mornye team?
Both are supported by the characters' kits, and neither mode should be treated as universally superior. Tune Rupture allows the team to trigger its associated response damage when the required Interfered state is applied, while Tune Strain builds damage through the relevant stack and Tune Break Boost interactions. The better choice depends on the enemy's Off-Tune state, how quickly the team can trigger its response, and the timing of Iuno's damage window. For players learning the team, reliable execution matters more than changing modes without a clear reason.
Does a Basic Attack DMG Bonus improve Iuno's Moonbow attacks?
No. Although Moonbow uses the Normal Attack button and has multipliers associated with her Normal Attack skill, its actual damage is classified as Resonance Liberation DMG. A Basic Attack DMG Bonus therefore does not boost those hits. Leveling Moon Steps can still improve its listed attack multipliers, but Liberation DMG bonuses are the relevant damage-type buffs for Moonbow.
