Cube: Bastion is the best cube for her since if you go for the treasure, she's highly invested.
Overload: 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.
Highest priority for everyone who cares about meta is Helm.
Better burst generation for the team, permanent attack damage buff, heals and great elemental damage for enemies weak to water.
This is by far the best treasure Shift Up has done.
Cube: Resilience cube for faster reload.
Overload: 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.
Cube: SMG units benefit from Bastion even at low investment. Quantum it's also a good option if you need more burst generation.
Overload: Max ammo capacity and hit rate are good lines. You don't really care what lines she gets since she will work out of the box.
The treasures in this category are consistently used in raids and even some bosses for campaign.
Drake has become a staple for shotgun teams. She’s also a nice buffer and her damage was increased thanks to the treasure.
Miranda is used on crit damage oriented teams, be it for one-shot teams with Snow White or even normal DPS teams with Rapi Red Hood.
Cube: Like all machine guns; Bastion. Unless you are super unlucky with overload stats and get no max ammunition, in that case run Resilience.
Overload: MG tank / support. Outside of getting max ammo capacity, you literally don’t care what she gets.
Cube: Resilience for better reloads. Avoid using Bastion or Wingman.
Overload: ATK and elemental damage take priority. Charge speed and damage for filler lines. Avoid getting max ammo capacity.
Cube: Adjutant will help her skills a lot. If not levelled up, Resilience it's a good pick.
Overload: Max ammo capacity and charge speed are priority. You'll have an easier time maintaining her buffs.
Cube: Resilience for faster reload.
Overload: 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.
Cube: Resilience cube for faster reload. If you get enough max ammo lines, you can also use Bastion.
Overload: Elemental DMG and ATK take priority as usual. Filler lines can be max ammo capacity and hit rate.
Treasures in this category are barely used even for raids or elemental content.
They are a buff in contrast to the original unit, but not enough to make a difference in the usage they get.
Not recommended to build unless waifu or you have one of those units with a lot of dupes.
Shift Up cooked one of the biggest pieces of trash I’ve seen in a while.
While her heals are an improvement over the base version, her CDR is so bad you are better off using Sakura instead as an off burst unit.
