Bready

A Burst 3 sniper DPS whose damage thrives in distributed damage lineups.
Her damage profile changes depending on the distributed damage increase and damage-over-time increase her allies grant.
Full Charge hits drive both her damage and debuffs; to offset the Charge Speed reduction, it is better to secure reload and Charge Speed boosts.

Lonely Gourmet1 grants herself Increased ATK at the start of Full Burst Time. When an ally gains damage-over-time increase, she gains Flavor to Stay, lowering her Charge Speed (cannot be removed), and Flavor to Share is cleared. When distributed damage increase is applied and she is not in a damage-over-time increase state, she gains Flavor to Share, lowering her Charge Speed (cannot be removed), and Flavor to Stay is cleared.

Favorite Candy2: every three Full Charge hits, if she has Flavor to Stay, applies Damage Taken increase and Aftertaste damage over time to the target. Each Full Charge hit, if she has Flavor to Share, grants herself Attack Damage increase and deals distributed damage based on final ATK to all enemies.

New FlavorB grants herself Attack Damage increase. With Flavor to Stay it adds an Aftertaste effect increase; with Flavor to Share it adds Increased ATK.

Charge fully, then fire at the targeted part.
Even on auto, as long as she mostly fires Full Charge shots, Favorite Candy2's condition keeps going.
In Flavor to Share lineups, aim manually only when you want to control where the enemy-wide distributed damage spreads.

There is only one Burst 2 slot, so lineups swap in other Nikkes that grant distributed damage increase, such as Anchor: Innocent Maid or Crust. Damage-over-time lineups pair her with Burst 2 Nikkes that grant damage-over-time increase, such as Rosanna: Chic Ocean.

To shorten Sniper Rifle reload windows, prioritize Resilience Cube. To ease Lonely Gourmet1's Charge Speed reduction, use a cube that raises Charge Speed. If Burst Gauge is slow, Quantum Cube is the runner-up. If Harmony Cube levels differ greatly, use the higher-level cube over the ranking.

Elemental Advantage damage and ATK are the baseline. Because of her Charge Speed reduction, prioritize Charge Speed lines. Adjust Max Ammo and Crit Damage with remaining lines based on weapon and range.

New FlavorB packs Attack Damage and branch enhancements together, so raise Burst first. Favorite Candy2 is the core of Full Charge damage and the distributed/damage-over-time branches, so raise S2 next. Lonely Gourmet1 is the entry buff and gateway for switching flavor states, so fill it with leftover resources.

Her damage picks up in boss fights against Fire Code enemies (= Water advantage). Swap her Burst 2 partner depending on distributed damage or damage-over-time lineups.

A single Full Charge shot can stack distributed damage and Attack Damage buffs at once.
In damage-over-time lineups, she applies both Damage Taken increase and Aftertaste damage over time.
New FlavorB further boosts ATK or Aftertaste effects depending on her flavor state.

Flavor to Stay and Flavor to Share cannot be maintained at the same time, so pick one based on your team's distributed damage or damage-over-time buffs.
Lonely Gourmet1's Charge Speed reduction lasts long, so without Charge Speed from gear, her Full Charge interval grows.
Her Burst cooldown is 40 seconds, so she rotates slowly in the Burst 3 slot.
