Skill recommendations
Build
CUBES
She can use either Resilience or Bastion depending on how much ammo you get and if there are reload speed buffers in the team.
OL GEAR
Like most DPS units, Elemental DMG and ATK take priority. After that, a couple lines of max ammo capacity are really good since she's an assault rifle.
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
- Even tho skill 2 increased MG wind up is useless, the ATK buff for the team is welcome
- Perfect synergy with Wind Asuka and consistently used together on elemental content (mostly raids)
- Loses all her value if not used with Wind Asuka since their kits were made to be used together
