Liino

endgame support

supportbufferhealeroff_fieldelectricarts_support

Liino ranks among the strongest supports: her stance grants a team-wide ATK buff, her Ultimate layers Will-scaled Electric and Nature Amp with forced Electrification, and she heals continuously. Her Battle Skill costs only 25 SP and her stance follows the controlled operator, so she fits nearly any lineup. She is slightly more valuable in Arts or Electric/Nature teams that can trigger her Combo Skill.

This endgame setup turns Liino into a buff-and-heal battery by leaning entirely into Will and Ultimate Gain. Bedazzling Night Debut supplies the largest Will injection plus a supportive Medicant effect, which raises the Amp ceiling of Dawnstar Concerto while also helping allies. The Eternal Xiranite armor, gloves, and Bracing Slab deliver heavy Will alongside an HP bump, and her Ultimate's Amp application triggers the set's team-wide DMG Dealt bonus for 15 seconds. A single LYNX Slab fills the remaining slot for extra Will and Ultimate energy. Because the set bonus cannot stack, this is the default choice when Liino is the sole Eternal Xiranite user, and the increased Ultimate efficiency keeps her Cosmovoice Stance windows frequent enough to maintain buff and heal uptime.

Insights

Core Mechanics

Dazzling Focus applies Electric damage and switches Liino into Vocalist Stance, which grants the whole team an ATK buff while periodically healing nearby allies and hitting enemies on a timed interval.
While in Vocalist Stance, applying or consuming an Arts Reaction on an enemy triggers Delightful Harmonics, which damages, heals the controlled operator, and refunds Ultimate Energy without interrupting the stance.
Dawnstar Concerto swaps Liino into Cosmovoice Stance, where she grants team-wide Electric and Nature Amp scaled by Will, forces Electrification in a large area, and deals periodic Electric damage per beat.
Starry Boost of 1st Magnitude refunds SP to an Electric or Nature operator who uses their Battle Skill within 30 seconds after Liino's Combo Skill procs.
Idol Zone raises healing received and lowers damage taken for allies standing inside her stance area, lingering briefly after they step out.
The stance area drifts toward the currently controlled operator, so Liino keeps healing and buffing whoever the player is piloting.

Scaling

Her Amp bonus converts Will at roughly 0.02% per point and caps near 40%, so stacking Will directly raises her Ultimate's buff ceiling.
Ultimate Gain Efficiency is the second lever: more of it means the 160-cost Ultimate comes back faster and the Cosmovoice windows overlap more often.
Peak performance is tied to a team that can cycle Arts Reactions during her Vocalist Stance and that has Electric or Nature operators to consume the SP refund.
Compared to dedicated damage dealers she scales gently, since almost all her value is amplification and sustain rather than personal multipliers.
In teams already saturated with DMG% buffs, some weapon options lose relative value, so support-oriented picks tend to age better than damage-oriented ones.

Team Role

Liino functions as an off-field amplifier and sustain engine rather than a direct damage source. She opens a fight by dropping into Vocalist Stance with Dazzling Focus, which supplies a team-wide ATK buff plus rolling healing to whoever is nearby, and she keeps that stance alive by letting allied Arts Reactions punch through her Delightful Harmonics Combo Skill for extra healing, damage, and Ultimate Energy. When her Ultimate meter fills, Dawnstar Concerto converts her into a stronger Cosmovoice Stance that layers Electric and Nature Amp on top of the ATK buff, forces Electrification onto a wide area, and periodically chips enemies while healing the team. Because her effects are generic buffs and healing, she slots into nearly any lineup, but she shines brightest in Electric or Nature Arts teams that can feed her Combo Skill reliably and use the SP refund from her Talent. Positioning is forgiving since the stance follows the controlled operator, so players can focus on reaction timing instead of running her around the map.

Explanation

The weapon slot prioritizes Bedazzling Night Debut because both plain Will and its team-oriented skill push Liino's Amp and support output simultaneously.

Golden Age is the fallback when the top option is unavailable; it still gives Will and a team buff, though the damage portion gets diluted in compositions that already pour out DMG% bonuses.

JET trades support utility for personal stats, edging out some lower-rarity picks purely on raw damage contribution, while Cohesive Traction is the budget option that keeps some Will and Electric bonuses.

On the gear side, Eternal Xiranite body, hands, and slab combine high Will with a team damage buff that Liino activates through her Ultimate's Amp application, and a single LYNX Slab off-piece adds useful Will and Ultimate Gain.

Use this configuration whenever Liino is the only Eternal Xiranite wearer on the squad.

Notes

Bedazzling Night Debut is the top pick because it feeds a large chunk of Will into her Amp scaling while also handing the team a Medicant-based boost.
The buff tied to Dawnstar Concerto is what turns on the Eternal Xiranite set condition, so her teammates get the extra damage window basically for free.
Remember that the Eternal Xiranite effect does not stack, so this build is at its best when no other support is running the same set.
