ZweiHas Favorite Item

An Electric Burst 1 Supporter Shotgun.
She raises squad pierce and Crit and also takes care of cover. Using her Burst switches her to a Charge Shotgun, changing how firing feels.

Her Burst Overcharge FormulaB switches her to a Charge Shotgun weapon. Charge time, Full Charge damage, and Max Ammo are as stated in the skill text. Additionally, it grants all allies Pierce Damage increase for 10 seconds.
Pierce Equation1 grants all allies Pierce Damage increase twice when Full Burst Time starts (lasting 1 shot and lasting 10 seconds per the skill text).
Frame Analysis2 restores ally cover HP every five normal attacks, and briefly grants allies Increased Critical Rate when Full Burst Time starts.

Auto is fine. Shotguns have spread, so they often miss depending on distance, and the Charge Shotgun is more stable when aimed by hand. To time buff triggers with Full Burst start, manual is better.

Reinforce Shotgun tempo with reload (Resilience Cube) and ammo refill (Bastion Cube), and as a Burst 1 unit, Burst Gauge (Quantum Cube) is also an option.

Fit remaining lines, such as Max Ammo and Crit, to how the weapon feels.

Many of her skills are Full Burst start buffs and normal attack conditions, so raise Burst and skills first, then the rest.

Often used for squad buffs and pierce support in Story and bosses. Arena and Tower depend on the squad.

She applies pierce and Crit buffs at Full Burst timing and can also take care of cover.

Her weapon mode changes after Burst, which changes how firing feels. As a Shotgun, if you cannot manage range and spread, relying on buffs alone is a waste.
