Skill recommendations
Build
CUBES
Pierce is the best if you have fast rotations since she will reload on burst. Resilience as usual a good option for any unit, and Destruction can be used for bosses but it's more situational.
OL GEAR
She has a fixed charge speed so you can ignore that. Elemental and ATK take priority as usual. 1 line of max ammo is good since her base capacity is pretty low. The rest focus on critical damage and rate. IF YOU RUN PIERCE CUBE, it is better to have 2 lines of max ammo because her breakpoints are weird. Either 2 lines or a single black line.
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
- OG Snow White but on steroids: double one-shot on burst, way stronger self buffs, and automatic AoE damage thanks to skill 1
- High burst generation thanks to her sequential attacks, if timed properly the team can re-enter burst almost instantly
- Can be used everywhere: single target is incredibly strong thanks to her burst while keeping good AoE clear thanks to her skill 1 Lock On mechanic
- If you play her on auto she can miss her burst quite often since enemies in NIKKE jump around constantly. This is more nitpicking than an actual con, since she is a really well rounded character
- Skill 1 could be replaced with a Wikipedia page and most players would not notice (myself included)
