Build
CUBES
Resilience. She takes 2.52 seconds to reload so there is no reason to use any other cube at the moment.
OL GEAR
Charge speed and max ammo capacity are the only lines she really cares about to help her with skill 1. Low priority to overload.
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
- DOUBLES Electric assault rifle units damage even without full investment (but there is just Scarlet at the time of her release)
- Amazing burst generation (second highest at the time of her release). The only character providing more it's Helm with her treasure
- Only Scarlet and Jill can benefit from her buffs since they are oriented towards assault rifles
- Skill 2 is completely useless if you don't have invested electric assault rifles
- Wording on skill 2 might confuse some players. Buffs are applied to only one assault rifle in the team going left to right for the priority on who gets that buff
- Part of her burst skill is wasted if your damage dealers don't deal AoE damage
