Cube: Resilience for faster reloads, she's a slow girl. You could run Bastion or Adjutant if you have enough max ammo or a reload speed buffer on the team.
OL Gear: You only care about Elemental DMG. You can ignore ATK since she gets so much on her own. Max ammo capacity as filler is nice to get.
How do you properly manual her?
The hold 0.5 second buff:
At the beginning of the battle and after full burst IF milk bursted.
The pierce buff on skill 1:
If you have no max ammo capacity lines, every other magazine you have to reload, full charge shot (usually less than 6 seconds, but easier to remember this way), spam the rest.
If you have more ammo, you'll have to do a full charge every 5 seconds instead.
