Wuthering Waves: Ultimate Iuno Build Guide (Best Weapons, Echoes & Ascension Materials)
Unlock the full potential of the 4-star Fusion character Iuno in Wuthering Waves (WuWa). This comprehensive build guide covers everything you need to know to maximize her effectiveness, including her best weapons, optimal Echo sets and stats, team synergy, and all required ascension materials.
Iuno Overview & Role
- Element: Fusion
- Rarity: 4-Star
- Weapon: Rectifier
- Primary Role: Sub-DPS / Support (Energy Generation, Fusion DMG Support)
- Tier Rating: S-Tier (Highly Effective in her role)
Iuno excels at generating Energy for her team while dealing consistent Fusion damage off-field. Her Outro Skill provides valuable Fusion DMG Deepen buffs, making her a strong support unit for Fusion main DPS characters like Jiyan.
Best Weapons for Iuno in Wuthering Waves
Choosing the right Rectifier significantly boosts Iuno's Energy Regeneration and support capabilities:
- Cosmic Ripples (5-Star - Best-in-Slot):
- Why: Its high Energy Regen stat and passive effect that boosts ATK% and provides team-wide Energy restoration upon using the Resonance Skill perfectly align with Iuno's support role. The Energy restoration helps her and her teammates use their Ultimates more frequently.
Augment: Abysslayer (5-Star):
- Why: Offers a substantial Energy Regen sub-stat and increases Resonance Skill DMG. While slightly less focused on team support than Cosmic Ripples, it's an excellent alternative, especially if you have it.
Stonard (4-Star - Craftable/F2P Friendly):
- Why: The best readily accessible option for most players. Its Energy Regen sub-stat is crucial for Iuno. The passive boosts Resonance Skill DMG after using the Intro Skill, synergizing well with her kit.
Thundering Tides (4-Star):
- Why: Provides a good Energy Regen sub-stat. The passive boosts Basic Attack DMG, which is less optimal for Iuno's off-field focus but still functional if Stonard isn't available.
Alternatives: Use any Rectifier with an Energy Regen sub-stat until you acquire Stonard or better options.
Best Echo Sets & Stats for Iuno
Iuno's Echo setup focuses on maximizing Energy Regen to spam her Ultimate and support abilities, followed by Fusion DMG and ATK%.
- Best Echo Set:
- 5-Piece Celestial Light (Best Support): This set is tailor-made for support characters like Iuno. Using her Outro Skill triggers the 5-piece effect, granting all team members a significant ATK% boost for a duration. This synergizes perfectly with her role.
- Alternative Echo Sets:
- 2-Piece Celestial Light + 2-Piece Lingering Tunes: Provides a solid Energy Regen bonus (2-pc Celestial Light) and an ATK% boost (2-pc Lingering Tunes). A good option if you lack a full Celestial Light set.
- 5-Piece Void Thunder (Situational DPS): Only consider this if building Iuno as a main DPS (less optimal). Prioritize the support sets instead.
- Cost 4 Echo (Main Stat Priority):
- Energy Regen: The absolute top priority stat for Iuno. This ensures she can use her Ultimate frequently, generating massive Energy for the team.
- Echo Substats Priority:
- Energy Regen% (Highest Priority)
- ATK%
- Fusion DMG Bonus%
- Crit Rate / Crit DMG (Lower priority than ER/ATK for support role)

Prepare these materials to level up Iuno and unlock her full potential:

Best Teams for Iuno
Iuno shines as a support/sub-DPS enabling Fusion main DPS characters:
- Core Synergy: Iuno + Jiyan (Main DPS): This is her premier team. Iuno generates massive Energy for Jiyan and buffs his Fusion DMG with her Outro Skill.
- Flexible Third Slot: Choose based on needs:
- Havoc Rover: Provides strong off-field DPS and Havoc shred.
- Verina: Offers powerful team-wide healing and DMG% buffs.
- Baizhi: Provides healing and ATK buffs.
- Sanhua: Offers strong on-field DPS during downtime and buffs Basic/Heavy Attack DMG.
- Another Support: Like Yangyang for additional Energy or Aalto for grouping.
How to Play Iuno Effectively
- Off-Field Focus: Iuno primarily functions off-field. Use her Resonance Skill to deploy her drones for consistent Fusion DMG and Energy particle generation.
- Energy Generation: Her core strength is generating Energy for the team. Prioritize Energy Regen stats and use her Ultimate frequently.
- Buff Timing: Use her Outro Skill strategically before switching to your main DPS (like Jiyan) to grant them the Fusion DMG Deepen buff.
- Swapping: Rotate Iuno in to use her Skill and Burst, then quickly swap out to your main DPS to maximize field time for your primary damage dealer.
By following this build guide, you'll equip Iuno with the best weapons, Echoes, and stats, gather her ascension materials efficiently, and integrate her seamlessly into powerful team compositions to dominate in Wuthering Waves.
