Skill recommendations
Build
CUBES
Resilience for faster reload. She can also use either Rupture or Pierce cube since she has both pierce and true damage.
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.
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
- True damage finally gets some usage. If you pair her with the Frima treasure, Laplace has great damage output (but way too expensive)
- Like all treasures, pretty expensive to build and fully invest considering you need gear, skills and the doll itself
- Can't cover during her burst, making her an easy target depending on the boss mechanics
