Skill recommendations
Build
CUBES
Resilience. If you have enough OL max ammo lines, can use Bastion. You can also run Quantum if you need more burst generation.
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.
ATK, Elemental DMG and Max Ammo Capacity take priority like most units. Since she is a support unit, you don't have to worry too much about what she gets tho.
Synergies & notes
By today's standards, a really bad kit that's just underwhelming on most (if not all) PVE content. Invest only if she is your waifu.
Solo Raid Usage
