Skill recommendations
Build
CUBES
She's a slow girl overall (2 second reload, animation lock, etc.) so Resilience always.
OL GEAR
Elemental damage and ATK take priority. Get enough max ammo capacity so she has at least 10 bullets for faster max stacks on her skill 1.
Solo Raid Usage
This is based on the top 50 players of all NIKKE servers combined. Data is from enikk.app, check their website for a lot more raid data.
Pros & Cons
- Cheap to build damage dealer in both gear and skills (you can ignore skill 2 and just get Ele DMG and ATK)
- After Shift Up fixed her sustained damage, one of the strongest damage dealers in the game, even on neutral content
- Easy to slot into any team composition as a DPS, her personal buffs are not that big so any support helps her damage output
