Anis: Sparkling SummerLimited

Anis: Sparkling Summer is a Burst 3 Shotgun Nikke who gives Electric allies ATK and Reload Speed while pushing damage with S2, which triggers on the last bullet.
During Burst her ammo drops sharply so last-bullet shots chain continuously, and she shines in Electric-weak boss fights and PvP.

Activating the Burst Skill sharply lowers Max Ammo and raises Reload Speed and Elemental Advantage Attack Damage, creating a flow of quickly firing last bullets. When a last-bullet attack hits, S2 triggers, dealing damage to the 2 enemies with the highest final ATK and raising her own Damage to Interruption Parts for a set time.

When Full Burst Time starts, S1 grants all Electric allies ATK and Reload Speed, speeding up the squad's damage rotation too. So Sparkling WaveB first secures last-bullet frequency, and Full Burst raises the damage environment for Electric allies, completing Burst Time damage.

Auto is usually enough. After activating Burst, keep the squad from leaving combat quickly so last-bullet shots are not interrupted.
In Electric boss fights, time the Burst phase to when S1's buff is active.

Pair her S1 buff with Electric DPS allies (especially Scarlet), and Privaty smooths out the last-bullet-based S2 rotation.

Among Harmony Cubes, Assault Cube boosts Elemental Advantage Attack Damage, making her stronger during her Burst's Elemental Advantage damage phase. Resilience Cube raises Reload Speed to increase last-bullet frequency. Bastion Cube adds ammo charging, reducing firing gaps across the Burst cycle.

Avoid Max Ammo-dependent lines and prioritize Elemental Advantage damage, ATK, and Critical Rate and Critical Damage. Her damage relies on last-bullet triggers, so crit lines are more efficient than Hit Rate.

S2 is her damage core, so raise S2 quickly. Raise S1 to the level needed to sustain the Electric ally buff, and keep Burst low for basic use, though from 9 the last-bullet rotation gets easier.

In story and campaign, she is efficient thanks to the Electric ally buff and S2 last-bullet damage. In boss fights, during Electric-weak phases, her Burst's ammo reduction and Elemental Advantage damage combine for strong damage. In PvP, last-bullet S2 lands quickly, and S1's buff builds damage pressure in sustained fights with Electric squads.

Damage keeps stacking during Burst by meeting the last-bullet condition.
She grants all Electric allies ATK and Reload Speed, speeding up the squad's damage rotation too.
S2 also raises Damage to Interruption Parts, helping with part phases.

S2 is tied to the last bullet, so damage drops sharply if ammo management does not fit.
Without Electric allies, S1's buff loses value, which limits squad options.
Teams that greatly raise Max Ammo clash with her Burst's ammo reduction and lower efficiency.
