Iuno Build Guide

What to know before spending pulls

Her full two-form loop, healing domain, and 50% Heavy Attack Outro work at S0. Intro plus Liberation immediately supplies the full 100 Sentience needed for a New Moon damage sequence. Blessing of the Wan Light is conditional: a character inside Full Moon must gain a shield to receive its stacking All DMG Amplification.

Do you need the signature weapon?

Moongazer's Sigil is Iuno's featured weapon. At level 90 it has 500 ATK and 36% Crit Rate. Intro or Liberation grants 20% Liberation DMG Bonus for 15 seconds, and gaining shields builds up to five stacks of 7.2% Liberation DEF ignore. Intro immediately grants all five stacks for 3 seconds. Aether Strike is the listed 4-star Crit option with 413 ATK and 40.5% Crit DMG; Liberation grants 7.2% ATK and 10.8% Liberation DMG Bonus for 15 seconds. Moongazer's Sigil has the stronger shield-linked package, while Aether Strike activates from the Liberation already used to begin each Lunar Cycle.

Another character copy or the weapon?

S1 means Iuno's first Resonance Chain upgrade. Lunar Cycle grants 40% ATK, Full Moon restores one Resonance Energy per second to Iuno, and Arc Beyond the Edge plus Absolute Fullness become immune to interruption. Moongazer's Sigil instead gives Crit Rate and shield-triggered Liberation damage and DEF ignore. S1 improves the cycle's safety and repeat energy; the weapon directly strengthens the Liberation-classified attacks already present at S0.

Advice for your account

Easy rotation

Enter with Intro to gain 40 Sentience, then cast Beneath Lunar Tides to add 60 and activate Lunar Cycle in Half Moon with a full meter. Use Heavy Attack - Flux: Moonbow to switch into New Moon. Spend Sentience with Moonbow Basic Attacks and Arc Beyond the Edge; these actions deal Liberation damage, restore extra Concerto, and heal the team. When Concerto is full, cast Absolute Fullness to end Lunar Cycle, heal, deal damage, and create Full Moon. Use Outro during Absolute Fullness or immediately after it, handing the 50% Heavy Attack amplification to the intended carry.

Opening vs. repeat cycles

Intro plus Liberation is the fastest full-Sentience opener. Without Intro, Liberation supplies 60 and Half Moon attacks must restore the remaining 40 before the New Moon spend. Closing Refrain can also activate Lunar Cycle and grants 25 Sentience, but it requires one of its five-second setup triggers first.

Why this skill priority

Forte Circuit and Liberation lead because Lunar Cycle, both forms, Sentience, Absolute Fullness, Full Moon, healing, and Blessing are the center of Iuno's kit, and her New Moon attacks count as Liberation damage. Resonance Skill adds New Moon movement and damage while helping spend Sentience and build Concerto.

Required buffs and assumptions

The fast opener assumes Intro and Liberation are both available. Full Moon can be created only when Concerto is full, and Absolute Fullness can trigger once every 25 seconds. Blessing stacks require the active character to gain a shield inside the domain; Iuno's personal shield does not transfer when she switches out.

Energy Regen target

No minimum Energy Regen target is listed in the current build data. Liberation is still central because it activates Lunar Cycle and restores 60 Sentience. Celestial Spiral can restore 6 Resonance Energy through Skill, while Aether Strike and Moongazer's Sigil focus on the Liberation damage window.
