Skill recommendations
Build
CUBES

Bastion or Resilience. Does not really matter unless you want to build her as a sub DPS.
OL GEAR
Most support units do not usually care about specific lines outside the CP padding for their buffs (caster's ATK when applicable) and increasing survibavility.
ONLY IF YOU ARE BUILDING HER AS A SUBDPS: Elemental damage and ATK take priority. Max ammo and crit can be filler lines.
Synergies & notes
One of the strongest debuffers for Iron weak content in the game while also providing extra CDR.
If you get her, worth using (super cheap to build) for both Solo and Union raids on any Iron team.
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 information.
Usage shown is based on the date the unit was released to avoid empty spaces on previous raids.
