Iuno is a 5-star Aero Resonator in Wuthering Waves who wields gauntlets and combines sub-DPS, shielding, and team healing in a single flexible kit. She cycles through lunar states to generate and spend Sentience, creating shields, restoring HP, and amplifying team damage while still contributing respectable personal output through her Resonance Liberation. Built correctly, Iuno becomes the backbone of heavy attack and sustain-focused teams that want both survivability and burst damage.

How Iuno’s Kit and Lunar States Work

Iuno’s gameplay revolves around the “Lunar Cycle” mechanic: she alternates between Half Moon, New Moon, and Full Moon states, each tied to different parts of her kit and to her unique Sentience resource. In Half Moon, she builds Sentience by using skills and attacks, and in New Moon she spends Sentience through enhanced skills to deal more damage and generate Concerto and healing.

When a heavy attack is used at the right point in the cycle, she ends the Lunar Cycle and creates a Full Moon domain that persists on the field for 30 seconds, periodically restoring HP and stamina to all Resonators and granting stacks of Blessing of the Wan Light whenever shields are generated. Multiple parts of her kit can generate shields, which not only protect the party but also interact with her Echo set choices and weapon passives that scale with shield gain. At higher Resonance Chain levels she gains additional buffs and utility, but even at base she offers strong healing, shielding, and sub-DPS through Resonance Liberation and enhanced skills.

Best Weapons for Iuno

Iuno’s damage is heavily concentrated in her Resonance Liberation and enhanced skills, so she benefits most from gauntlets that increase ATK, Crit, and Liberation damage, and that often tie extra effects to her shields. Her signature gauntlet Moongazer’s Sigil stands out as the best overall option, with several strong alternatives for different budgets and loadouts.

Recommended weapons

• Moongazer’s Sigil (5-star, signature gauntlets): Moongazer’s Sigil is Iuno’s best-in-slot weapon, increasing ATK% and Resonance Liberation damage while allowing her to ignore up to 36% of enemy DEF as she generates shields and stacks the passive. Since her kit naturally produces frequent shields and a large portion of her DPS comes from Liberation, this weapon directly maximizes both her burst potential and overall damage efficiency.
  
• Verity’s Handle (5-star, high-DPS gauntlets): Verity’s Handle grants a flat 12% damage increase and an additional 48% Resonance Liberation damage, aligning well with Iuno’s Liberation-centered playstyle. It does not offer the DEF ignore of Moongazer’s Sigil but is still an excellent choice for players who want to emphasize her burst damage.
• Aether Strike (4-star, Battle Pass gauntlets): Aether Strike provides ATK% and Resonance Liberation damage whenever Liberation is cast and additionally offers Crit Rate as a substat, which helps reach comfortable crit thresholds on a lower rarity weapon. This makes it one of the strongest 4-star options for Iuno, especially in lineups that rely on her Liberation as a major source of DPS.
• Other high-stat 5-star gauntlets: Any offensive 5-star gauntlet with ATK% and Crit stats can perform well, even if not tailored specifically for Iuno, because her damage scales significantly with raw stats and Liberation multipliers.

Best Echo Sets and Main Echo

Iuno’s Echo build needs to balance personal damage, shields, and team support. She benefits greatly from sets that reward shield generation and increase ATK, Crit, Aero damage, and Resonance Liberation damage.

Echo sets

• Crown of Valor (3-piece) + Aero damage set (2-piece):A 3-piece Crown of Valor combined with a 2-piece Aero set such as Sierra Gale, Gusts of Welkin, or Windward Pilgrimage is frequently recommended as Iuno’s best general-purpose configuration. Crown of Valor grants ATK and Crit Damage that stack whenever shields are created, and Iuno can easily reach and maintain the 5-stack requirement because multiple skills and passives give shields. The 2-piece Aero set adds 10% Aero damage, directly amplifying her kit since she deals Aero damage across her skills.
  
• Moonlit Clouds (support-oriented alternative):Moonlit Clouds can be used to emphasize support and energy rather than pure damage, providing energy regeneration and team-oriented utility for lineups that want Iuno primarily as a healer and buffer. This works especially well in teams where other Resonators cover most of the DPS while she focuses on sustain and buffs.
  
• Rejuvenating Glow or healing-focused blends:Some external guides mention using Rejuvenating Glow or similar healing sets in builds that prioritize Iuno’s role as a dedicated healer and shield provider, granting extra healing power and occasional team ATK buffs when healing is applied. These can be combined with Aero sets if a hybrid healer-sub-DPS role is desired.

Main Echo

• Lady of the Sea (main Echo): Lady of the Sea is widely considered Iuno’s best main Echo, providing both Aero damage and Resonance Liberation damage bonuses and belonging to the Crown of Valor set. Its Echo Skill summons a Tidestorm that deals multiple hits of Aero damage followed by a strong final hit, while also granting 12% Aero damage bonus and 12% Resonance Liberation damage bonus to the equipped Resonator, perfectly matching Iuno’s damage profile.
  

Echo stats and substats

Proper stat distribution ensures both sustained support and strong burst damage.

• Main stats
• 4-cost Echo: Crit Rate or Healing Bonus, depending on whether the build leans more toward damage or sustain.
• 3-cost Echoes: Aero damage bonus where available.
• 1-cost Echoes: ATK% for general scaling.
• Substats
• Crit Rate and Crit Damage as the primary offensive substats to boost Liberation and skill damage.
• Aero damage bonus and Resonance Liberation damage where possible.
• ATK% and a moderate amount of Energy Regeneration (around 120–125%) to keep Resonance Liberation available consistently.

Skill Leveling Priority

Iuno has multiple healing and shielding sources, but a large share of her offensive impact comes from her Resonance Liberation and enhanced skills, so skill leveling should follow that priority.

• Resonance Liberation – first priority: Liberation provides a large portion of Iuno’s personal DPS and gains substantial value from both her weapon and Echo choices, making it the most important skill to level. Higher levels translate directly into stronger burst windows and faster enemy clears.
  
• Forte Circuit / Enhanced Skill path – second priority: The Forte node that governs Sentience and the enhanced skills used in New Moon is central to her sub-DPS role and to generating damage and Concerto. Upgrading it increases the damage of her empowered skill usage within Lunar Cycle.
  
• Resonance Skill – third priority: Resonance Skill is used frequently during Lunar Cycle and changes behavior in New Moon, contributing both damage and resource management. Leveling it enhances her rotational output and helps maintain consistent shield and Sentience usage.
  
• Normal Attack and Intro Skill – lower priority: Normal attacks and Intro damage contribute less overall than the above abilities but still gain some value in extended fights and should be leveled later once core skills are upgraded.

Team Compositions and Synergies

Iuno fits particularly well into heavy attack-focused and shield-conscious compositions, where her Outro and shielding interactions can greatly increase team damage and survivability.

Team role and typical partners

• Iuno – sub-DPS, healer, shielder, and buffer: Acts as a hybrid unit who offers healing via Full Moon domain and various skills, provides consistent shields, and supports team damage while adding liberation-based burst. Her ability to trigger Crown of Valor stacks makes her especially effective in teams that benefit from constant shield generation.
  
• Heavy attack main DPS: Many team examples pair Iuno with heavy-attack-focused carries, taking advantage of her shield-based buffs and Outro heavy attack damage amplification mentioned in external kit breakdowns. This synergy allows the main DPS to safely stay on field under strong shields and increased damage.
• Flex slot – support, healer, or extra DPS: The third slot can be filled by a pure healer or shielder if extra survivability is needed, or by an additional DPS or sub-DPS that capitalizes on Aero debuffs, Echo Skill damage, or heavy attack amplification. In setups where Iuno already covers a large part of the healing, the flex slot often becomes an offensive choice.

Basic Rotation Tips for Iuno

Iuno’s rotation weaves together Lunar Cycle phases, Sentience management, and shield triggers. The goal is to maintain Crown of Valor stacks, keep Full Moon active when possible, and ensure Liberation is used at high Sentience for maximum effect.

A practical rotation example:

• Start with another Resonator to apply initial buffs or debuffs, then switch Iuno in via her Intro when Concerto allows.​
• On entering, use Resonance Skill to activate Lunar Cycle and enter the Half Moon phase, then generate Sentience through basic attacks and skill usage.
  
• Jump or follow the prescribed input to shift into New Moon, then use enhanced instances of Resonance Skill or Forte Skill to spend Sentience for increased damage and Concerto gain.
  
• When Sentience is sufficiently spent and Concerto is close to full, perform a heavy attack to end the Lunar Cycle, creating a Full Moon domain that restores HP and stamina to the team over time and gains Blessing of the Wan Light stacks with each shield generated.
  
• Cast Resonance Liberation during or immediately after the domain begins, benefiting from ATK, Crit, and Liberation bonuses from weapons and Echo sets, and then rotate to other Resonators while Full Moon continues to support the team.
  

Repeating this pattern ensures frequent shields and healing, consistent Valor stacking, and strong Liberation bursts, allowing Iuno to stabilize and empower the team throughout longer encounters.

Iuno is a versatile 5-star Aero gauntlet Resonator who combines sub-DPS, healing, shielding, and team damage amplification through a unique lunar-themed kit in Wuthering Waves. With Moongazer’s Sigil or another strong Liberation-focused gauntlet, a Crown of Valor–centered Echo setup anchored by Lady of the Sea, carefully tuned Crit, Aero, and Liberation stats, and teams that appreciate shields and heavy attack amplification, she becomes a powerful centerpiece for both safe progression and high-end content.
