Skill recommendations
Build
CUBES
Avoid Bastion for her damage taken debuff. Assault (hit rate) or Quantum (burst generation) can work if they are high level. If they are not invested, run everyone’s favorite, Resilience.
OL GEAR
Avoid max ammo capacity so she has an easier time with her damage taken debuff. Outside of that, the usual DPS build with Elemental and ATK. Crit lines and hit rate as filler so she can hit cores with more consistency.
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
- Strongest B3 buffer in the game by far and FINALLY it seems like Shift Up is learning how to make proper treasures
- Can be used both as offburst and normal DPS unit. If you only care about offburst usage, her skills can be 10/10/4
- The amount of buffs she provides makes any team hit harder regardless of element, so you can use her anywhere (not only on Water weak content)
- Her main downside: burst generation. You will ALWAYS lose burst generation regardless what team you slot her in. Easy to solve nowadays, but still important to mention
