Wuthering Waves has introduced Iuno, the Priestess of Septimont, a 5-star Aero Resonator who attacks with powerful Gauntlets. At first glance, she appears to be a versatile Sub-DPS, offering shields, team-wide healing, and stamina recovery. However, Iuno is one of the most specialized and niche-defining Resonators in the game.
Her true potential is locked behind a unique synergy, making her an S-tier partner for one specific character while being a replaceable option for everyone else. This guide will meticulously break down how to build Iuno, her best-in-slot weapons, her complex kit, and the exact team you need to make her shine.
Iuno Character Overview & Lore (Who is Iuno?)
Before we dive into her build, let’s look at the Resonator herself.
Iuno | Rarity | Element | Weapon | How to Get | Voice Actor (EN) |
|---|---|---|---|---|---|
Iuno | ★★★★★ | Aero | Gauntlet | Limited Convene | Ella Boyes |
Iuno’s entire kit revolves around her Lunar Cycle Forte, allowing her to switch between two states: Half Moon (which generates her “Sentience” resource) and New Moon (which consumes “Sentience” for powerful attacks).
Crucially, her gameplay also creates a Full Moon Domain. While inside this domain, any Resonator who gains a Shield also gains a stack of Blessing of the Wan Light. At 10 stacks, this buff provides a massive 40% All DMG Amplification. This is the secret to Iuno’s power.

Main DPS | A | A | A |
Sub-DPS | SS | SS | SS |
Strengths & Weaknesses
Strengths:
Insane Buff Potential: Provides a 40% All DMG Amp buff (via
Blessing of the Wan Light) and a 50% Heavy Attack DMG Amp (via Outro Skill).Team Utility: Offers consistent team-wide healing and stamina recovery via her
Full Moon Domain.Self-Sufficient: Can create her own shields (via Inherent Skills) to proc her
Crown of ValorEcho set.Good Personal Damage: Her personal damage, which scales off Resonance Liberation, is very respectable for a support.
Weaknesses:
Extremely Niche (The Augusta Problem): Her core 40% All DMG Amp buff requires a Main DPS who can generate 10 shields in a single rotation. Currently, the only character who can do this is Augusta. Without Augusta, this entire part of her kit is unusable, and her value drops significantly.
Late-Game Materials: Her Ascension and Forte materials are found in late-game areas, making her difficult to level for new players.

The Best Iuno Build: Aero Sub-DPS
To maximize Iuno’s potential, you must build her as an Aero Sub-DPS, focusing on Crit, Aero DMG, and Resonance Liberation DMG.

Iuno Best Echo Sets Explained
Iuno is one of the few characters who can perfectly utilize the Crown of Valor set.
Best: 3-pc Crown of Valor + 2-pc Sierra Gale
Why? This is her undisputed best-in-slot. Because Iuno’s Inherent Skill grants her a shield, she can proc the
Crown of Valor5-pc effect all by herself, gaining a massive 30% ATK and 30% Crit DMG. The 2-pcSierra Galeprovides a simple 10% Aero DMG boost.Main Echo:
Lady of the Sea(This Echo is perfect, as it belongs to theCrown of Valorset and provides both Aero DMG and Resonance Liberation DMG bonuses).
Support-Focused: 5-pc Moonlit Clouds
Why? A viable alternative if you are still farming
Crown of Valoror want to provide a more generic ATK buff to your team. This sacrifices Iuno’s personal damage for a team-wide 22.5% ATK buff.Main Echo:
Impermanence Heron
Iuno Best Weapons Explained
Iuno’s weapons focus on buffing her ATK and, most importantly, her Resonance Liberation DMG.
Moongazer’s Sigil (5-Star Signature):
Skill (Plenilune Radiance): Increases ATK by 12%. Casting Intro or Liberation increases Liberation DMG by 20%. Gaining a Shield allows Liberation DMG to ignore 7.2% of the target’s DEF, stacking 5 times.
Verdict: Her perfect weapon. It provides ATK, a massive Liberation DMG buff, and DEF ignore that she can trigger instantly with her Intro Skill.
Verity’s Handle (5-Star Standard):
Skill (Ad Veritatem): Gain 12% Attribute DMG Bonus. Using Liberation grants 48% Liberation DMG Bonus for 8s. This can be extended by casting Resonance Skills.
Verdict: A phenomenal alternative. It provides a huge, unconditional Liberation DMG buff that she can easily maintain.
Blazing Justice (5-Star Standard):
Skill (Darkness Breaker): Increases ATK by 12%. Casting Basic Attack lets damage ignore 8% DEF and amplifies Spectro Frazzle DMG by 50%.
Verdict: A decent stat stick for its high base ATK, but the effect is mostly wasted on her.
Tragicomedy (4-Star Battle Pass):
Skill (Fool’s Warble): Increases ATK by 12%. Casting Basic Attack or Intro Skill increases Heavy Attack DMG Bonus by 48% for 3s.
Verdict: A solid 4-star option if you use her Heavy Attack
Absolute Fullnessoften.
Aether Strike (4-Star Craftable):
Skill (Oath of Tide Hunters): Casting Liberation increases ATK by 7.2% and grants 10.8% Liberation DMG Bonus for 15s.
Verdict: A good F2P-friendly option that directly buffs her Liberation.
Stonard (4-Star Standard):
Skill (Wallbreaker): When Resonance Skill is cast, increases Liberation DMG Bonus by 18% for 15s.
Verdict: Another excellent 4-star option, arguably better than
Aether Strikeif you can manage its trigger.
Iuno’s Best Team Compositions
Iuno’s team building is extremely restrictive. She has one S-Tier team and several B-Tier teams.
. Augusta Heavy Electro Team (Iuno’s Best-in-Slot Team)
This is the only team that can currently utilize Iuno’s Blessing of the Wan Light (40% All DMG Amp) buff, as Augusta is the only character who can generate 10 shields in one rotation.
Augusta (Main DPS): 3-pc Crown of Valor + 2-pc Void Thunder
Iuno (Sub-DPS): 3-pc Crown of Valor + 2-pc Sierra Gale
Shorekeeper (Support): 5-pc Rejuvenating Glow
General Rotation:
Start with Shorekeeper and build Concerto. Cast Liberation (Stellarealm) and switch to Iuno.
Iuno enters via Intro. Immediately cast Resonance Skill (to enter
Lunar Cycle), then Jump (to switch toNew Moonstate), then Resonance Liberation (to maxSentience).Perform the
New Mooncombo:Basic Attack (x3) → Resonance Skill → Resonance Skill.Cast Heavy Attack (Absolute Fullness) to create the
Full Moon Domain.Outro Skill to Augusta (giving her 50% Heavy Attack Amp).
Augusta takes the field inside the Domain. As she performs her combos, she will rapidly generate shields, gaining the 10 stacks of
Blessing of the Wan Lightfor a 40% All DMG Amp.Once Augusta’s combo is finished, switch back to Shorekeeper to repeat.
2. Iuno Main DPS Team (Alternative)
If you don’t have Augusta, you can run Iuno as your on-field Main DPS. This team is functional but significantly weaker as it does not use her primary buff.
Iuno (Main DPS): 3-pc Crown of Valor + 2-pc Sierra Gale
Ciaccona (Sub-DPS): 5-pc Gusts of Welkin (for Aero RES Shred)
Rover (Aero) (Support): 5-pc Rejuvenating Glow
General Rotation:
Start with Aero Rover for buffs and healing. Outro to Ciaccona.
Ciaccona builds Erosion stacks, uses Heavy Attack to group enemies, and casts Liberation. Outro to Iuno.
Iuno enters via Intro. Cast Resonance Skill (enter
Lunar Cycle), then Jump (enterNew Moon).Use one Enhanced Skill (to spend some
Sentience), then Resonance Liberation (to refillSentience).Perform her full damage combo:
Basic Attack (x3) → Enhanced Skill → Basic Attack (x3).When Concerto is full, switch back to Aero Rover.

Iuno’s Resonance Chain (Sequence Nodes)
Iuno’s S2 is one of the most important constellations in the game for enabling her specific team.
Recommended Stopping Points:
S2 (Amazing): This is her most crucial node. It unlocks the 40% All DMG Amp buff for her team. For Sub-DPS Iuno, this is her biggest power spike.
S6 (Amazing):G A massive personal damage increase that turns her into a formidable DPS in her own right.

Final Verdict: Is Iuno Worth It? (Should I pull for Iuno?)
Iuno is an S-Tier, game-changing support… but only if you have, or are fully committed to building, Augusta.
Her S2 Resonance Chain, which unlocks her 40% All DMG Amp, is one of the most powerful support buffs in the game. When paired with Augusta, she enables a top-tier team that shreds content.
Pull for Iuno if:
You have Augusta as your main DPS. Iuno is her best-in-slot partner, and it’s not close.
You have Iuno’s S2 (or are pulling for it), as this is where her main buff comes from.
You enjoy a complex, technical Sub-DPS who provides healing, shields, and massive buffs.
Be Cautious if:
You do not have or want Augusta. Without Augusta, Iuno’s primary buff (
Blessing of the Wan Light) is completely wasted, and she becomes a simple healer/Heavy Attack buffer, a role that Shorekeeper can often do better.You are a new player. Her materials are all in the late-game Sanguis Plateaus.
