An Iron, Burst stage 3 Assault Rifle Attacker Nikke.
She often fills the Burst 3 DPS slot in content like Solo Raid where enemies are Electric.
She attacks sequentially at random targets, so she is at a disadvantage in fights where you must hit a single core or one part for a long time.

At the start of battle, Impact-Type Exospine1 grants a permanent Increased Critical Rate. When her normal attacks land 44 crits, she attacks sequentially at random enemies with Unstable Energy, and if the target hit is Electric, it applies a damage-taken increase.

At the start of battle, Eagle Eye-Type Exospine2 permanently grants Increased ATK based on caster's ATK and Increased Max Ammunition Capacity. When her normal attacks land 10 hits and the current target is Electric, she gets an ammo refill.

Her Counter ChainB Burst attacks sequentially at random enemies several times, and for a short time applies Exospine Mk2, raising the Unstable Energy damage multiplier and the Eagle Eye-Type Exospine2 ATK increase multiplier by one step. Her Burst Cooldown is 40 seconds.

First check on the lineup screen whether the enemy is Electric. If not, her ammo refill and damage-taken debuff do not trigger.
Auto is enough by default.
Against bosses where you must hit a core or specific part for a long time, her firepower scatters because she attacks sequentially at random targets.

Solo Raid data shows examples splitting slots like Burst 1 Little Mermaid, Burst 2 Crown, and Burst 3 EVE. Lineups that put Mast: Romantic Maid in Burst 2 to add a Critical Damage buff also appear.

As an Assault Rifle, Reload Speed directly affects her firing tempo. Prioritize the Resilience Cube and support ammo with the Bastion Cube. If Harmony Cube levels differ a lot, choose the higher-level cube over the theoretical ranking.

Crit hit conditions and Burst windows weigh heavily, so you can run a high share of Critical Damage lines. Max Ammo lines can be reduced depending on your setup.

Unstable Energy and Crit Rate are both on S1, so raise S1 first. Her Burst's Exospine Mk2 amplification is large. S2 covers ATK, ammo, and ammo refills, so it can be filled last.

She fills the Burst 3 DPS slot in content that targets Iron advantage, such as boss fights, Solo Raid, and Union Raid where enemies are Electric. As a main DPS just for clearing main story, her random hits and the Electric enemy condition can be a burden.

Against Electric enemies she can aim for a damage-taken increase and ammo refills together.
She has a Crit Rate buff, so Unstable Energy triggers fairly reliably.

Her Burst and Unstable Energy hit random targets as she attacks sequentially, so focusing on a core or single part is hard.
As an Assault Rifle, her core hit efficiency tends to be worse than Sniper Rifle and Rocket Launcher units.
