Trony

A Fire Sniper Rifle Burst 3 Attacker Nikke.
Her damage relies heavily on the Cumulative Damage Skill applied by Full Charge and the self-buffs from her Burst Skill, so output drops when conditions are not met.
Her rating since release has been fairly low, so she is rarely used as a main DPS candidate and often goes in favorite-character teams or for element matching.

When a Full Charge bullet hits, the Cumulative Damage Skill is briefly applied to the single enemy closest to the reticle, and part of the damage she deals accumulates in that state; when it reaches the cap, it detonates and deals distributed damage to enemies within the attack range. Using her Burst Skill grants herself Increased ATK and an increased Cumulative Damage Skill damage accumulation ratio at once, reaching detonation faster in the same engagement.

After filling Full Charge, move the reticle close to the enemy you want to newly apply the Cumulative Damage Skill to, and fire.
Use her Burst Skill during Full Burst windows while Increased ATK and the accumulation ratio increase are active.
If Full Charge timing is inconsistent on auto alone, accumulation breaks, so switch to manual if needed.

Stabilize the Full Charge cycle with reload and ammo refill. Fit Charge Speed and Max Ammo to Full Charge and reload patterns. If Harmony Cube levels differ a lot, use the higher-level cube before the theoretical ranking.

Elemental Advantage damage and ATK are the baseline. Add Charge Damage and Charge Speed to raise Full Charge share. Cover Hit Rate with gear and remaining lines.

The active with the Cumulative Damage Skill and her Burst self-buff drive her damage, so raise those two first, and adjust the middle slot to the in-game growth table and squad.

The Cumulative Damage Skill shows its value in boss fights where she can fire at a single enemy for a long time. In story battles where mobs change often, her priority drops if clearing speed matters more.

Her Burst Skill grants both Increased ATK and an increased Cumulative Damage Skill damage accumulation ratio at once.
When the Cumulative Damage Skill detonates, distributed damage hits enemies in range.

Her Cumulative Damage Skill has a short duration, so she must land many shots in a short time.
As a Sniper Rifle, she fills Burst Gauge at a modest pace.
