Key Strengths:
Primary Weaknesses:
Moongazer's Sigil (5★)
This is Iuno's signature weapon and overwhelmingly her best option. The combination of high Crit Rate, ATK boost, Resonance Liberation DMG amplification, and DEF ignore makes it irreplaceable for maximizing her damage output.
Verity's Handle (5★)
Xiangli Yao's signature weapon works surprisingly well on Iuno, providing substantial Crit Rate and the highest Resonance Liberation DMG bonus available, making it the best alternative if you don't have her signature weapon.
Blazing Justice (5★)
Zani's signature weapon offers excellent Crit DMG and DEF ignore capabilities, making it a solid choice for players who pulled during Zani's banner.
Abyss Surges (5★)
Available on the standard banner, Abyss Surges provides strong ATK stats and Energy Regen, making it a reliable option for F2P players.
Aether Strike (4★) - Battle Pass Weapon
This is the best 4-star option for Iuno, available through the Battle Pass. It provides excellent Crit DMG and substantial buffs to both ATK and Resonance Liberation DMG.
Stonard (4★) - Battle Pass Weapon
Another Battle Pass option that focuses on Crit Rate and massive Resonance Liberation DMG amplification, making it nearly as good as Aether Strike.
Tragicomedy (4★)
This weapon synergizes well with Iuno's Heavy Attack amplification capabilities, making it a solid choice for teams built around Heavy Attack DPS characters.
Marcato (4★)
The best F2P option, Marcato provides massive Energy Regen and Concerto Energy restoration, helping Iuno maintain her rotation more easily.
3pc Crown of Valor + 2pc Aero DMG Set
This is Iuno's best-in-slot echo configuration. Since she can generate shields through her kit, she can consistently maintain the 5-stack Crown of Valor bonus, resulting in 30% ATK and 20% Crit DMG. Combined with the Aero DMG bonus, this setup maximizes both her personal damage and team utility.
Main Echo: Lady of the Sea
Lady of the Sea is the perfect main echo for Iuno, providing both damage types she needs most while offering crowd control capabilities that help her maintain the Crown of Valor stacks.
5pc Moonlit Clouds
This build sacrifices Iuno's personal damage to provide more buffs to the incoming Resonator. It's a good early-game option if you haven't unlocked Sanguis Plateaus yet, but you should transition to Crown of Valor as soon as possible for endgame content.
Main Echo (Alternative): Impermanence Heron
This main echo choice further emphasizes the support role, funneling more damage into your main DPS character.
| Cost Slot | Priority | Stat |
|---|---|---|
| 4-Cost | Highest | Crit Rate or Crit DMG |
| 3-Cost | High | Aero DMG% |
| 3-Cost | Medium | Aero DMG% (second piece) |
| 1-Cost | Medium | ATK% |
| 1-Cost | Low | ATK% (second piece) |
The optimal cost pattern for Iuno is ④③③①¹. This configuration allows you to maximize your main stats while maintaining the flexibility needed for different content types.
Roles:
Why This Team Works: This is Iuno's optimal team composition, leveraging the perfect synergy between Iuno and Augusta. Augusta can generate shields rapidly, allowing Iuno to maximize her Blessing of the Wan Light buff (40% All DMG amplification at 10 stacks). Additionally, Iuno's Outro Skill provides 50% Heavy Attack DMG buff, which Augusta heavily benefits from. Shorekeeper provides Crit and ATK buffs while ensuring team survival.
Rotation:
Roles:
Why This Team Works: While Jiyan can't maximize Iuno's Blessing of the Wan Light like Augusta can, he still benefits significantly from Iuno's Heavy Attack DMG amplification and healing capabilities. This team offers more flexibility and is easier to build for players who don't have Augusta.
Roles:
Why This Team Works: For players who want to use Iuno as their main damage dealer, this hypercarry composition focuses on maximizing her personal damage while providing the necessary support to keep her alive and amplify her output.
Roles:
Why This Team Works: This budget-friendly option uses Verina instead of Shorekeeper and works with any Heavy Attack-focused DPS character. While not as optimal as the Augusta composition, it still provides excellent results for F2P players.

Iuno's gameplay revolves around two distinct states:

Maximizing Crown of Valor:
Blessing of the Wan Light Optimization:
Many players focus solely on damage stats and neglect Energy Regen. Iuno needs 120-125% ER to maintain her rotation comfortably. Always prioritize this stat before stacking excessive ATK or Crit DMG.
Avoid using full Moonlit Clouds set in endgame content. While it has early-game utility, Crown of Valor hybrid provides significantly better results for Iuno's role.
Don't force Iuno into teams that can't utilize her Heavy Attack DMG amplification. She works best with Heavy Attack-focused DPS characters like Augusta and Jiyan.
Don't level Normal Attacks before Forte Circuit and Inherent Skill. These are her core abilities and should be prioritized for maximum effectiveness.
Avoid staying in Half Moon state too long. New Moon state is where Iuno deals most of her damage and provides team utility.
Yes, Iuno is absolutely worth pulling, especially if you have Augusta or plan to build Heavy Attack-focused teams. She provides unprecedented utility as both a sub-DPS and support, with excellent damage output and team-wide buffs that make her valuable in almost any composition.
Iuno's unique combination of damage output, healing, and damage amplification makes her stand out. Unlike pure supports, she can deal substantial damage while providing 40% All DMG amplification (with Augusta) and 50% Heavy Attack DMG buff, making her a "jack-of-all-trades" that excels in multiple areas.
While primarily designed as a sub-DPS/support, Iuno can function as a main DPS in hypercarry compositions with the right investment and team support. However, she reaches her maximum potential when paired with Heavy Attack DPS characters who can fully utilize her buffs.
While Moongazer's Sigil is her best weapon, Iuno performs well with several alternatives including Verity's Handle, Aether Strike, and Stonard. Her signature weapon provides the highest damage potential, but she remains effective with F2P options.
Crown of Valor focuses on maximizing Iuno's personal damage through shield-stacking mechanics, while Moonlit Clouds emphasizes support utility for the team. Crown of Valor is superior for endgame content, while Moonlit Clouds can work for early-game or support-focused builds.
Iuno offers a unique combination of damage and utility that few other supports can match. While pure healers like Verina provide more consistent healing, Iuno offers comparable healing while dealing substantial damage and providing powerful damage amplification buffs.
Iuno excels in all content types but particularly shines in endgame challenges like Tower of Adversity and Whimpering Wastes, where her combination of damage, healing, and buffs provides maximum value.
Energy Regen is crucial for Iuno, with target values of 120-125%. This ensures she can maintain her rotation comfortably and use Resonance Liberation when needed for both damage and healing.
Iuno stands as one of the most versatile and powerful characters in Wuthering Waves 2025, offering unprecedented flexibility between sub-DPS and support roles. Her unique lunar cycle mechanics, combined with powerful team buffs and consistent damage output, make her an invaluable addition to any roster.
Whether you're building her alongside Augusta for maximum synergy or using her to support other Heavy Attack DPS characters, this guide provides everything you need to maximize Iuno's potential. Remember to focus on Crown of Valor echo sets, prioritize Crit stats and Energy Regen, and build teams that can fully utilize her Heavy Attack DMG amplification capabilities.
As the meta continues to evolve, Iuno's versatility ensures she'll remain a top-tier choice for both casual and endgame content. Start building your ideal Iuno setup today and experience the power of Septimont's prodigious Priestess!
