Admi

A Wind Burst 2 Sniper Rifle Nikke who supports allies' Charge, reload, crits, and survival through hits taken and her Burst.
She is rarely a main pick in story, bosses, Raids, or Arena.
She is rated low in recent PvE and PvP alike, so unless she is a favorite, her investment priority is low.

Every time she is hit 20 times, all allies receive a long Charge Damage multiplier increase. Using her skill reduces damage taken by the two allies with the highest final ATK, and using her Burst grants all allies Reload Speed and Increased Critical Damage together.

Keep up rapid fire and taking hits to cycle Helping Hand1.
Time her Burst with Full Burst to grant reload and crit buffs.
Leave her on auto by default, and if she is not taking 20 hits often, just adjust her front-line position.

There is little evidence of her being paired in the same squad in the recent meta.

To match her Burst reload buff, the Resilience Cube comes first. Cover her own sniper accuracy with the Assault Cube and ammo with the Bastion Cube. If Harmony Cube levels differ a lot, use the higher-level cube before the ranking.

As a support unit, her Overload priority is low. To make use of her own Charge play, set Charge Speed and Hit Rate lines later.

Unless she is a meta core unit, save skill books and only raise Helping Hand1, Kitten's Breath2, and Burst to 4 when you use her. Maxing to 10 gives little return for the investment.

She was used in older Scarlet reload lineups but is rarely seen now. Her share in top Solo Raid lineups is also very low.

Her Burst grants all allies Reload Speed and Increased Critical Damage.
Kitten's Breath2 reduces damage taken by the two allies with the highest ATK.
Every 20 hits taken, allies' Charge Damage multiplier rises.

Helping Hand1 needs her to be hit 20 times, so it triggers late or drops off.
The Burst 2 slot is crowded relative to her buff values, so she is rarely a main pick.
She adds almost no firepower herself, so her value feels low for the investment.
