Skill recommendations
Build
CUBES
Resilience for faster reload times and higher uptime on her buffs.
OL GEAR
Usual DPS build; Elemental DMG and ATK take priority. Charge speed is really good too depending how many rocks you are willing to use. A line of ammo is nice even if it goes against skill 1.
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 synergy with characters that proc their skills when they are healed (like Crown)
- Best (at the time of her release) burst generation in the game. Makes no sense how good Shift Up decided to make this treasure
- Can be used as an offburst just for the buffs, heals and extra burst generation OR you can use her as your main Water DPS. Incredible damage on elemental content
- Like all treasures, pretty expensive to build and fully invest considering you need gear, skills and the doll itself
