Skill recommendations
Build
CUBES
Resilience cube since she has last bullet mechanics, you want to avoid using Bastion. You can also use Vigor or Healing if you need extra healing output.
OL GEAR
Support unit that doesn’t benefit from specific lines. Avoid getting Max Ammunition since it will make her heal less consistently.
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
- Best belly in the game
- Good sustain for the team plus storage mechanic. Will keep your team alive and doesn't require a lot of investment
- Base heals don’t scale up with buffs or OL gear. Since she is a pure healer with no actual offensive buffs, it is pretty hard to justify using her nowadays
