Should You Pull?YES

Yes for Aero Heavy Attack amp—Iuno feeds Heavy Attack hypercarries. Liberation “Beneath Lunar Tides” routes damage through mid-air / plunging attack chains. Best with Jiyan / Mortefi / Shorekeeper. Heavy Attack Outro is wasted on Skill/Liberation-only carries. Skip when Mortefi already fills Heavy amp and you lack a Heavy Attack DPS.

Iuno is a 5★ Aero Main DPS who fights with a Gauntlets. Liberation “Beneath Lunar Tides” routes damage through mid-air / plunging attack chains. Forte “Ebb and Flow” restores HP across threatened allies while banking Concerto.

Strengths

  • Liberation “Beneath Lunar Tides” routes damage through mid-air / plunging attack chains — that window is where Iuno’s clear speed actually shows up.
  • Forte “Ebb and Flow” restores HP across threatened allies while banking Concerto, so resource banking is mandatory, not optional filler.
  • Outro “From Gloom to Gleam” hands the next Resonator a Heavy/Basic Attack Amplification window — swap timing is part of the damage plan, not just Concerto filling.
  • Aerial / plunge routes give flexible dodge and reposition options mid-combo.

Weaknesses

  • Field-time hungry once Liberation “Beneath Lunar Tides” is up — double-DPS swaps dilute the dump window.
  • Wants dedicated supports and ER planning; dropped into a random squad, Liberation uptime falls off a cliff.

Team Compositions

Premium Iuno shell: Augusta is the Dual-DPS / quickswap partner; Chisa is the Dual-DPS / quickswap partner. Rotation: open Augusta / Chisa for Concerto → Intro Iuno → Liberation / Forte dump. Chisa is only best in slot with yangyang-xuanling - prioritize Shorekeeper with Augusta.

Character Synergy
Iuno
IunoMain DPS

Iuno is the on-fielder — bank Concerto on Augusta / Chisa, Intro in, then dump Liberation / Forte inside their amp windows.

Augusta
AugustaMain DPS

Augusta shares field time with Iuno — trade Intro / Outro so both Liberation windows get amp coverage.

Chisa

Chisa shares field time with Iuno — trade Intro / Outro so both Liberation windows get amp coverage.

Forte CircuitEbb and Flow

Lunar Cycle Iuno can activate Lunar Cycle by casting Resonance Skill - Closing Refrain or Resonance Liberation. Lunar Cycle has two states: Half Moon and New Moon. By default, Iuno enters the Half Moon state when activating Lunar Cycle and can switch between the two states by casting Heavy Attack - Flux. When in Lunar Cycle: - Iuno's Jump is replaced with Heavy Attack - Flux. STA won't recover when Iuno is in mid-air. - Iuno's movement becomes Meandering, which consumes STA continuously in mid-air to move in a unique manner. - Performing environmental interactions, using Utilities, or holding Jump will end Lunar Cycle. Lunar Cycle - Half Moon Iuno attacks using the Moonring, restoring Sentience on hit. She can use Heavy Attack - Flux: Moonbow to deal Aero DMG (considered as Resonance Liberation DMG) and switch to Lunar Cycle - New Moon. Heavy Attack - Flux: Moonbow can be cast in mid-air. Lunar Cycle - New Moon Iuno attacks using the Moonbow. While in this state, casting Moonbow - Basic Attack, Resonance Skill - Arc Beyond the Edge, or Moonbow - Dodge Counter consumes Sentience to increase the skill's DMG Multiplier, restore additional Concerto Energy, and heal nearby Resonators in the team. Iuno can use Heavy Attack - Flux: Moonring to deal Aero DMG (considered as Resonance Liberation DMG) and switch to Lunar Cycle - Half Moon. Heavy Attack - Flux: Moonring can be cast in mid-air. Heavy Attack - Absolute Fullness When Iuno's Concerto Energy is full, her Heavy Attack is replaced with Absolute Fullness. Casting Absolute Fullness ends Lunar Cycle, provides healing for nearby Resonators in the team, deals Aero DMG to nearby targets (considered as Resonance Liberation DMG), and conjures a Full Moon domain at her location. This effect can be triggered once every 25s. Can be cast in mid-air. Full Moon Domain Resonators inside the domain periodically restore HP and STA. Gaining a Shield inside the domain grants 1 stack of Blessing of the Wan Light. This effect can be triggered once every 0.5s. Blessing of the Wan Light The receiving Resonator gains 4% all DMG Amplification for 10s, stacking up to 10 times. Gaining new stacks resets the duration. This effect ends early if the receiving Resonator is switched off the field. Sentience Iuno can hold up to 100 points of Sentience. Casting Intro Skill restores 40 points of Sentience. Casting Resonance Liberation restores 60 points of Sentience. Casting Closing Refrain or Unfinished Refrain restores 25 points of Sentience. When Iuno is in Lunar Cycle, Moonring - Basic Attack, Moonring - Dodge Counter, and Mid-air Attack restore Sentience on hit.

S1Wax or Wane, All Gild the Bough

When Iuno is in Lunar Cycle, her ATK is increased by 40%. When Iuno is inside the Full Moon Domain, she additionally restores 1 point of Resonance Energy per second. Resonance Skill - Arc Beyond the Edge and Heavy Attack - Absolute Fullness become immune to interruption.

Is it worth getting?

Comfort opener: Raises party ATK from a Stellarealm / team aura. Nice QoL/damage, but S0 still runs the full kit — don’t break pity for S1 alone.

S2Day or Night, Let This Be EternalPull Target

Resonators in the team with 10 stacks of Blessing of the Wan Light gain an additional 40% all DMG Amplification.

Is it worth getting?

Stat-leaning S2: Extra Amplification on Liberation / attribute damage. Clear damage, but it does not rewrite Iuno’s rotation the way a mechanic Sequence would.

S3I Drink Deep of Their Forgetting

When Iuno is in Lunar Cycle, DMG dealt by Moonbow - Basic Attack, Resonance Skill - Arc Beyond the Edge, and Moonbow - Dodge Counter is Amplified by 65%. Within a certain period after performing Moonbow - Basic Attack or Moonbow - Dodge Counter, casting Resonance Skill - Arc Beyond the Edge does not reset the cycle of Moonbow - Basic Attack.

Is it worth getting?

Situational S3: Extra Amplification on Liberation / attribute damage.

S4Rainy Season Dwell in My Eyes

Casting Heavy Attack - Absolute Fullness grants a Shield equal to 160% of Iuno's ATK to all Resonators in the team for 30s, which cannot be passed on to the incoming Resonator.

Is it worth getting?

Side-grade: Adds RES / DEF shred or a large DMG Bonus clause. Happy if it drops; not a planned stopping point.

S5A Thousand Futile GlimpsesSkip

Iuno gains 20% Resonance Liberation DMG Bonus.

Is it worth getting?

Late luxury: Adds RES / DEF shred or a large DMG Bonus clause. Grab it if you overshoot toward S6 — never hard-pity for S5 alone.

S6I Am the Constant in the ChaosSkip

The DMG Multiplier of Heavy Attack - Absolute Fullness is increased by 1600%. Upon casting this skill, Iuno re-enters Lunar Cycle - New Moon, gains 100 points of Sentience, and resets all the cooldown of Resonance Skill - Arc Beyond the Edge.

Is it worth getting?

Whale ceiling: Adds RES / DEF shred or a large DMG Bonus clause. Only chase if Iuno is your dedicated main and S0–S2 already feel finished.

Iuno is fully usable at S0. Most dedicated mains stop at S2 before chasing higher Wavebands. First stop: S2. Endgame target: S2.
