OL Gear: Elemental DMG and ATK if you are building her as a damage dealer. If you only want to use her as a support for shotgun teams, you can just get max ammo capacity and hit rate as extra lines.
✅ Pros
Incredible buffer for shotgun teams that can dish out good damage at the same time
Cheap to build if you want to use her as a support
Staple unit for both shotgun teams and fire elemental content thanks to her treasure
❌ Cons
Like all treasures, pretty expensive to build and fully invest considering you need gear, skills and the doll itself
