CUBES
Like most units in the game, Bastion and Resilience are the best options to run depending how many lines of max ammo you get on the OL gear.
OL GEAR
Elemental damage and ATK take priority. After that crit lines benefit her A LOT for the extra damage on marcato. A couple lines of max ammo capacity are great since you can switch from Resilience to Bastion.
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 on neutral content she's doing pretty well. We finally are getting more and more characters that benefit from crit rate and crit damage rather than the same 3 lines every other unit uses
- Expensive price tag on a character that will be used mostly for raids considering the RNG on doll materials and upgrades
- Not a great option to farm daily Iron weak boss (Ultra), since you want to bring units that can pierce like Red Hood, Snow White or Laplace
