LIINO BUILD GUIDE: WEAPONS, GEAR & TEAMS

Liino is Endfield’s first idol operator, and she headlines Version 1.4 Phase 2 with her Good Morning From Your Dawnstar banner going live August 9, 2026. If you have been saving Oroberyl since her name dropped at the Companionship Celebration program, this is the Liino build guide you actually need: which weapon carries her, which gear sets turn her Vocalist and Cosmovoice stances into a real team-wide engine, and the Electric compositions that make her worth the pull.

Here is the caveat, stated once so the rest of this guide can be practical: Liino’s kit mechanics are officially confirmed, straight from the July 10 Homecoming program, but her exact numbers (skill values, cooldown lengths, SP costs) land when her banner opens on August 9. So this is a day-one build direction grounded in her confirmed kit and the real systems already live in the game (gear sets, weapon data, the current roster), not a reprint of a leaked spreadsheet. When a number is a launch unknown, we say so.

TL;DR - Key Points

• Liino is a 6-star Electric Supporter, Endfield’s first idol-archetype operator, built around a Battle Skill/Ultimate stance switch rather than a stat comparison like Arcane.
• Vocalist Stance (her Battle Skill) trades her Basic Attack for continuous team ATK gain, healing nearby operators, and periodic attacks.
• Cosmovoice Stance (her Ultimate, “Dawnstar Concerto”) is the payoff window: team-wide heal, large-area damage, forced Electrification, a stronger ATK buff, stronger healing, and Electric plus Nature Amp for the whole team.
• Her Combo Skill, “Delightful Harmonics,” fires whenever an enemy gets an Arts Infliction or Reaction applied or consumed, healing the controlled operator, dealing Electric damage, and refilling Ultimate Energy on a short cooldown.
• BiS weapon is her signature Bedazzling Night Debut (Polearm, Will main, Treatment Efficiency sub), purpose-built for a Medicant-style support build.
• Best gear leans on LYNX for her healing kit, Eternal Xiranite for the team buff her own Amp application triggers, and Catastrophe for faster Cosmovoice cycling.
• Best teammates are Zhuang Fangyi and Avywenna (both feed on her SP refund and Amp), plus the designed Arcane-Liino Corrosion showcase team with Perlica and Ardelia.
• Banner: Phase 2 “Good Morning From Your Dawnstar” runs August 9 to August 30, with Arcane, Camille, Ember, Lifeng, Ardelia, Last Rite, and Pogranichnik as off-rate 6-stars.
• She is a support first, healer second. Her own kit already carries that warning: pair her with a dedicated healer for high-pressure content.

Who Liino Is

Liino is the idol that the community spent two patches speculating about, first as a silhouette in the 1.3 livestream, then as a pair of mecha legs in the IGN Live 2026 trailer. Her official reveal at the Companionship Celebration program confirmed what the design was building toward: an idol who fights, not just performs. If you want the full pre-reveal arc, our 1.4 idol operator analysis covers the original teaser and lineage theories, and our IGN trailer reaction digs into the mecha-idol design debate before her name was known.

Mechanically, she does not share Arcane’s stat-driven stance system. Liino’s two stances are tied directly to her Battle Skill and her Ultimate, which means you do not have to build around an Intellect-versus-Will comparison. What you do have to build around is keeping her cycling between the two stances as often as possible, since almost all of her value (team ATK, healing, Electrification, Amp) only exists while one stance or the other is active. Her banner-mate weapon is a Polearm, the same weapon type used by Chen Qianyu and Lifeng, though her stat priorities point toward a support build rather than a Physical carry.

Vocalist and Cosmovoice: The Stance System

Liino’s whole kit runs on two stances:

• Vocalist Stance, entered by her low-SP-cost Battle Skill. She loses access to Basic Attacks while it is active, but gains continuous team ATK growth, healing for nearby operators, and periodic attacks of her own.
• Cosmovoice Stance, entered by her Ultimate, “Dawnstar Concerto.” This is the burst window: a team-wide heal on activation, large-area damage output, forced Electrification on enemies, a stronger version of her ATK buff, stronger healing, and Electric plus Nature Amp granted to the whole team.

The practical read: Vocalist is her default, low-cost uptime state, and Cosmovoice is the payoff you want live as often as possible, since it is the only point in her kit where she forces Electrification and hands out Amp. Unlike Arcane, there is no wrong stat allocation that locks you into the weaker stance. Your job is Ultimate uptime, not stat-sheet management.

Liino’s Kit, Skill by Skill

Exact multipliers, SP costs, and cooldown lengths are a launch-day reveal. What follows is the confirmed behavior of each skill.

Battle Skill: Vocalist Stance

A low-SP-cost skill that puts Liino into Vocalist Stance. While active, she cannot perform Basic Attacks, but she continuously increases team ATK, heals nearby operators, and periodically attacks enemies on her own. This is her default state between Ultimates, and its low cost means you can enter it early and often without starving her other skills.

Combo Skill: Delightful Harmonics

This is the reactive half of her kit. It triggers whenever an enemy is affected by an Arts Infliction or Reaction, or when one of those is consumed, which makes it fire naturally in almost any team that is already applying elemental statuses. On trigger, it heals the operator you are currently controlling, deals Electric damage, and restores Ultimate Energy, all on a short cooldown. Her talent adds a team-wide layer: after using Delightful Harmonics, Liino grants a buff that gives other Electric operators a small SP refund the next time they use their Battle Skill. That refund is the mechanical reason she slots so cleanly into a mono-Electric composition.

Ultimate: Dawnstar Concerto

Her Ultimate heals the entire team on cast and puts her into Cosmovoice Stance. While active, she deals damage in a large area, forcibly applies Electrification to enemies, provides an enhanced team ATK buff, provides stronger healing, and grants Electric and Nature Amp to allies. This is the single skill that unlocks her forced-Electrification value, so anything that speeds up her Ultimate cycle (Ultimate Gain Efficiency, SP economy) is effectively speeding up her entire kit, not just one damage number.

Best Weapon

Liino’s signature weapon is purpose-built for exactly the role her kit wants.

Bedazzling Night Debut is close to a description of her intended role: a Will main-stat, Treatment Efficiency sub-stat Polearm confirmed to be built for support and healer-leaning operators. If you skip her weapon banner, Cohesive Traction is the strongest substitute, since its Combo Skill damage buff and stacking Electric DMG bonus after a Combo cast play directly into how often Delightful Harmonics fires. Aggeloslayer is a fully playable 4-star floor if you would rather spend Arsenal Tickets elsewhere. There is also a free option: the Protocol Pass weapon Golden Age shares her signature’s Polearm, Will, and Treatment Efficiency profile and is built around the same healing loop, as our Junction Point and Golden Age operator breakdown explains.

Best Gear Sets

Her weapon’s Treatment Efficiency sub-stat and her Ultimate’s team-wide Amp both point toward the same shelf of gear sets already live in the game.

LYNX is the first pick for a Liino who is genuinely filling the healer slot, since it converts her passive healing into a team-wide survivability buff without competing for anything else in her kit. Eternal Xiranite is the higher-ceiling damage-support pick, since her Ultimate is a guaranteed Amp application, but remember it does not stack: if Ardelia or Gilberta already runs it in your comp, put Liino on a different set instead of doubling up. Catastrophe and Frontiers both push the same lever from different angles, faster access to Cosmovoice Stance, so pick whichever matches whether your bottleneck is Ultimate Energy or Combo Skill cooldown.

The best new Wuling pieces for Liino

The Version 1.4 Wuling drop (23 new pieces) topped up her two core sets with exactly the substats a Will-main support wants:

• Eternal Xiranite Light Armor (Will 110 plus an Ultimate Gain Efficiency line) and the matching Wraps and Hands gloves (Will plus Ult Gain) are near best-in-slot for her damage-support build, stacking Will and the ultimate cycling that gets her into Cosmovoice Stance faster.
• LYNX Cuirass T1 and Gauntlets T1 (both Will, Agility, and Ultimate Gain) are the clean fodder for her healer build.
• The non-set Rift Trekker Light Armor rolls Will 115 with a Treatment Bonus (+10.8%) line, an ideal off-piece stat stick for a healer-leaning Liino.

Skip AIC Fieldwork on her: its bonus is all damage-dealt, which a support who is not the carry barely uses. Her upgrades are the Will and Ultimate Gain pieces above.

Stat and Essence Priority

1. Will (her weapon’s main scaling stat and the stat her kit is built around)
2. Ultimate Gain Efficiency (more time in Cosmovoice Stance is more forced Electrification and Amp uptime)
3. HP Treatment Efficiency (amplifies both her Vocalist passive heal and her Ultimate’s team heal)
4. HP (keeps her alive while she is stuck in Vocalist Stance unable to Basic Attack)
5. Cooldown Reduction on Combo Skill where available, to increase Delightful Harmonics uptime

For essence lines specifically, prioritize Will and Ultimate Gain first, then Treatment Efficiency once her core damage-adjacent stats are covered. She has no INT/WILL stance trap like Arcane, so there is no wrong stat to avoid, just a priority order to follow.

Best Teams for Liino

Nature and Electric Corrosion Showcase Team

Liino . Arcane (INT DPS) . Perlica . Ardelia

This is the designed 1.4 pairing, and it is not a coincidence that Liino and Arcane share a version. Liino’s Cosmovoice Stance force-applies Electrification and grants Nature Amp, which lays the second element Arcane’s Corrosion reaction wants and directly buffs Arcane’s Nature damage at the same time. Perlica adds more Electrification, and Ardelia is the Nature healer stacking Susceptibility on the side. Our full Arcane build guide covers Arcane’s half of this rotation in detail.

Zhuang Fangyi Electric Core

Liino . Zhuang Fangyi . Perlica . Ardelia

Zhuang Fangyi’s chain-lightning kit is exactly the kind of Electric carry that benefits from Liino’s talent-driven SP refund after Delightful Harmonics, plus her Ultimate’s Electric Amp. This is close to the current top-tier Electric shell with Liino slotted in as the support instead of a generic battery. If you run this team, the Zhuang Fangyi rotations and gear guide is the companion read for his side of the loop.

AoE Farming and SP-Loop Team

Liino . Arclight . Gilberta . Zhuang Fangyi

This shell is built around a specific unlock: Arclight’s Tempestuous Arc only pays out its full 50 SP when it consumes Electrification, which is why our SP battery tier list flags her as reaction-locked and inconsistent outside a dedicated Electric comp. Liino’s Cosmovoice Ultimate forces Electrification directly, so Arclight’s loop stays live without needing Perlica to babysit the trigger, freeing that slot for Gilberta instead. Gilberta groups enemies and layers Arts Susceptibility plus Nature Corrosion onto the pack (her teammate synergy breakdown covers the numbers), which shreds resistance for whatever Zhuang Fangyi’s chain lightning hits next. The result is a wave-clear and overworld-farming team rather than a single-target boss shell: Liino keeps the team buffed and healed, Arclight keeps the SP flowing, Gilberta keeps enemies grouped and debuffed, and Zhuang Fangyi cashes it all out across the whole pack.

Avywenna Sustain and Reaction Team

Liino . Avywenna . Perlica . Antal

Avywenna’s kit already leans on team Electric synergy, and pairing her with Liino stacks two operators feeding off the same SP-refund and Amp mechanics. Antal is the accessible Electric applicator that keeps Delightful Harmonics firing consistently.

F2P and Budget Team

Liino . Antal . Fluorite . Zhuang Fangyi

You do not need whale investment to make Liino function. Antal and Fluorite are accessible Electric appliers that keep her Combo Skill triggering, and Zhuang Fangyi is broadly obtainable through standard progression. Give her an Intellect-free Will-main weapon like Aggeloslayer, run Catastrophe for faster Ultimate cycling, and she carries her supporting role without a single limited pull.

Rotation Direction

Open with the Battle Skill to enter Vocalist Stance early and start the team ATK ramp, since it costs little SP and there is no reason to delay it. Let Delightful Harmonics fire naturally off your team’s existing Arts Inflictions and Reactions rather than forcing it, since its trigger condition is passive. Time your Ultimate for the moment you need forced Electrification or a team heal, ideally right before your carry’s own burst window, so the Amp and ATK buff land on the highest-damage rotation rather than a filler one. Exact cooldown windows are a launch-day detail, so refine this sequence once her real numbers are live.

How to Build Liino by Player Type

• F2P and light spender: Run a Will-main 4-star or 5-star weapon and Catastrophe. Her kit is fully functional as a secondary support without her signature.
• Mid-spend: Decide whether your roster’s healer slot or your Electric team’s SP economy needs her more. If you already run Ardelia, lean into Eternal Xiranite’s Amp synergy; if you need a dedicated healer, go LYNX.
• Whale: Bedazzling Night Debut plus a fast Ultimate-cycle gear set (Catastrophe or Frontiers) is the ceiling. Her duplicates likely affect Ultimate cycling and the SP-refund talent, so watch how they scale at launch.
• Support main: She is a rare kind of unit, a healer-and-buffer hybrid with a built-in Electric SP-economy tool. Just remember the kit’s own warning: she supplements a healer, she does not replace one.

Pull and Banner Advice

Liino headlines Phase 2 of Version 1.4, the “Good Morning From Your Dawnstar” banner, running August 9 to August 30, with Arcane, Camille, Ember, Lifeng, Ardelia, Last Rite, and Pogranichnik as off-rate 6-stars and her weapon banner “Bedazzled Issue” carrying Bedazzling Night Debut. If you want the full patch context, banner order, and every reward tied to the Homecoming update, our 1.4 Homecoming program recap has the complete rundown, including her narrative event and Combat Drills trial rewards. She is a limited operator, so keep a 120-pull floor before you start, and budget closer to double if you are also chasing Arcane for the designed synergy team. Run your own numbers in our pity calculator before committing.

Common Mistakes to Avoid

• Expecting her to solo-heal. Her healing is supplementary, not a dedicated healer’s output. Pair her with a real healer for high-pressure content.
• Skipping Ultimate cycling gear. Almost all of her unique value (forced Electrification, team Amp) lives in Cosmovoice Stance. A slow Ultimate cycle is a Liino who mostly just buffs team ATK.
• Doubling Eternal Xiranite. The team buff does not stack. If Ardelia or Gilberta already runs it, put Liino on LYNX or Catastrophe instead.
• Building her as a damage carry. Her periodic attacks in Vocalist Stance are a bonus, not her purpose. Stat lines should chase Will, Ultimate Gain, and Treatment Efficiency, not ATK or Crit.
• Ignoring the SP-refund talent’s team requirement. It only benefits other Electric operators. Running her in a mixed-element team wastes that piece of her kit.
• Treating pre-release numbers as gospel. Her mechanics are confirmed, but exact figures floating around before launch are estimates. Verify once her banner is live.

What Would Change This Guide

A few reveals at launch will sharpen these recommendations:

1. Her real skill values, SP costs, and cooldowns, which decide exactly how tight her Vocalist-to-Cosmovoice cycle is.
2. Her duplicate (potential) nodes, currently unpublished, which may extend Cosmovoice duration or deepen the SP-refund talent.
3. Confirmed gear set interactions, since her actual heal and Amp values will determine whether LYNX or Eternal Xiranite wins for a given team.
4. How Zhuang Fangyi and Avywenna’s own 1.4-era kits interact with her SP refund, since both were named as her intended partners.

We will update this guide with confirmed numbers the moment her banner is live.

Final Verdict

Liino is the rare kind of support who does three jobs at once: a healer, a team ATK buffer, and the SP economy engine for an entire Electric roster. Her stance system is simpler than Arcane’s stat-driven flip, since it is tied directly to her Battle Skill and Ultimate rather than a stat comparison you can build wrong. The real skill in building her is Ultimate uptime: everything that matters most about her kit, forced Electrification, team Amp, and her strongest heal, only exists in Cosmovoice Stance. Chase Will and Ultimate Gain, pick a gear set that matches whether you need her as a healer or a damage-support piece, and slot her into a mono-Electric team or the designed Arcane pairing to get full value.

Frequently Asked Questions

What element and class is Liino? Liino is a 6-star Electric Supporter, Endfield’s first idol-archetype operator. Her kit switches between Vocalist Stance (Battle Skill) and Cosmovoice Stance (Ultimate) rather than reading a stat comparison.

Is Liino a healer or a support? Both, but support first. Her own kit description warns that her healing is supplementary. Pair her with a dedicated healer for high-pressure content and treat her ATK buffs, forced Electrification, and Amp as her main value.

What is Liino’s best weapon? Her signature Bedazzling Night Debut (6-star Polearm, Will main, Treatment Efficiency sub) is best in slot. Cohesive Traction (5-star) is the strongest non-signature option, and Aggeloslayer (4-star) is a fully functional F2P floor.

What are Liino’s best gear sets? LYNX for a healer-leaning build (Treatment Efficiency plus DMG reduction on heal), Eternal Xiranite for a damage-support build (team DMG buff off her own Amp application), and Catastrophe or Frontiers to speed up her Ultimate and Combo Skill cycling.

How does Liino’s Combo Skill work? Delightful Harmonics triggers whenever an enemy has an Arts Infliction or Reaction applied or consumed. It heals your active operator, deals Electric damage, and restores Ultimate Energy, and her talent grants other Electric operators a small SP refund afterward.

Who are Liino’s best teammates? Zhuang Fangyi and Avywenna, both confirmed synergy targets that benefit from her SP refund and Electric Amp, plus the designed Arcane-Liino Corrosion team with Perlica and Ardelia.

When does Liino’s banner release? Her banner, “Good Morning From Your Dawnstar,” is Version 1.4 Phase 2 and runs August 9 to August 30, 2026. Arcane, Camille, Ember, Lifeng, Ardelia, Last Rite, and Pogranichnik are the off-rate 6-stars, and her weapon banner “Bedazzled Issue” carries Bedazzling Night Debut.

How many pulls should I save for Liino? At least 120 for the featured guarantee. If you are also targeting Arcane for the intended pairing team, plan for closer to double.

Is Liino worth pulling? If your roster needs a healer-and-buffer hybrid or a dedicated SP-economy piece for an Electric team, yes. She is a premium support unit, just not a damage carry, so judge her by what she does for your team rather than her own damage bar.

Do I need her signature weapon? No. A Will-main 5-star like Cohesive Traction covers most of her value. Bedazzling Night Debut is the ceiling for her Treatment Efficiency scaling, not a requirement.
