Liino

endgame support

supportbufferhealeroff_fieldelectricarts_support

Liino is rated at the very top because she brings a rare combination of team-wide ATK buffing, continuous healing, and Electric/Nature Amp from a single slot while barely costing the team anything. Her Battle Skill is cheap to fire and she keeps contributing even while benched. Her only real caveat is that her peak output leans on Arts-oriented setups to fuel her Combo Skill, but she still slides into nearly any composition.

This endgame setup is built around making Liino's Will as high as possible so the Electric and Nature Amp from Dawnstar Concerto hits its ceiling and stays active for as long as possible. Bedazzling Night Debut is the anchor weapon: it stacks Will for the Amp formula and its Medicant skill layers an extra buff onto allies at no cost to Liino's own healing or damage. The Eternal Xiranite armor, gloves, and kit piece provide the heaviest Will line in the game right now, and they fire a team-wide DMG Dealt increase whenever she applies Amp — which her Ultimate does automatically. A single LYNX Slab rounds the build out by adding more Will plus Ultimate Gain Efficiency, improving how often her strong window comes back up. The result is a support that is essentially never idle: cheap Battle Skill entries keep ATK buffing and healing flowing, and a fast Ultimate cycle keeps Amp coverage high. Use this when no other member of the squad is already wearing Eternal Xiranite.

Core Mechanics

Vocalist Stance is opened by the Battle Skill Dazzling Focus: it deals Electric DMG on entry, then grants the whole party an ATK boost, periodic healing for allies in range, and a repeating additional attack while Liino cannot Basic Attack.
While Vocalist Stance is up, the Combo Skill Delightful Harmonics fires whenever an Arts Reaction is applied to or consumed on an enemy, dealing Electric DMG, healing the controlled operator, and giving Liino extra Ultimate Energy.
The Ultimate Dawnstar Concerto swaps Liino into Cosmovoice Stance, which hands out Electric and Nature Amp scaled by Will, adds an ATK boost, forces Electrification onto enemies in a wide area, and pulses damage plus healing on a beat timer.
Ending either stance is done by pressing the Battle Skill again; doing so costs no SP but puts the skill on a short cooldown, and ending Cosmovoice Stance early forfeits the triple-strength closing burst.
Talent Starry Boost of 1st Magnitude refunds SP when an Electric or Nature operator casts a Battle Skill shortly after Liino's Combo Skill, and Idol Zone softens incoming damage and boosts healing received for allies standing in her area.

Scaling

The Amp portion of her Ultimate converts Will into extra percentage, so stacking Will is the main way to raise her buff ceiling; the stat has a hard cap on how much Amp it can contribute.
Ultimate Gain Efficiency is the second lever, since faster Ultimate cycling means more Cosmovoice Stance uptime and shorter gaps between Amp windows.
Early on she functions fine as a plain healer/buffer with basic gear, but her real payoff appears once Will and ULT Gain pieces come online and she is paired with Arts Reaction partners.
Her value also rises with team composition: Electric and Nature allies both benefit from her Amp types and help her Combo Skill trigger via reactions.

Team Role

Liino is a purely off-field support who never needs to occupy the controlled slot to do her job. She opens with Dazzling Focus to establish Vocalist Stance, which delivers a party-wide ATK buff and steady healing to whoever is nearby, then lets her allies' Arts Reactions drive Delightful Harmonics for extra healing, damage, and Ultimate Energy. Her Ultimate converts that energy into Cosmovoice Stance, layering Electric and Nature Amp on top of the ATK buff and forcing Electrification onto groups of enemies. Because her buffs are generic, she fits into virtually any roster, but she is at her strongest alongside Electric and Nature damage dealers who generate reactions on demand and benefit from both Amp types. Her stances follow the controlled operator automatically when she is off-field, so positioning is forgiving. In practice she sits as the team's sustain-and-amp anchor while other slots carry the damage, and her low Battle Skill cost lets her keep the loop running without starving the team of SP.

Explanation

Bedazzling Night Debut is picked as the top weapon because its large Will roll directly feeds the Amp scaling on Dawnstar Concerto, and its Medicant effect spreads an extra buff to teammates.

Golden Age is the closest substitute and still protects Liino's Amp through its Will Boost, though its Pursuit damage bonus loses a lot of value when the team is already swimming in DMG% buffs, such as in Zhuang Fangyi squads.

JET and Cohesive Traction trail behind because they mostly boost Liino's own damage rather than supporting the team; JET edges out Cohesive Traction, and Cohesive Traction is the practical fallback when nothing better is available.

The Eternal Xiranite set supplies the biggest Will totals and triggers its ally-wide DMG Dealt buff whenever Liino applies Amp, which her Ultimate does for the entire team.

The LYNX Slab off-piece fills the remaining slot with more Will and Ultimate Gain, tightening her Ultimate rotation.

Notes

Essence rolls should chase Medicant first, then Will Boost, then Treatment Efficiency Boost — this mirrors the weapon's own priority list.
Running one piece of the LYNX set in the second kit slot lets Liino pick up extra Will and Ultimate Gain without giving up the Eternal Xiranite team buff.
Remember the Eternal Xiranite bonus is a one-per-team effect, so a second user on the squad wastes it.
