Soldier FA

An Iron Burst 2 Defender Shotgun Nikke who holds out with a DEF buff when hit, healing based on damage dealt, and a Max HP increase from her Burst.
She is rarely a main pick in story, boss, or Raid main slots, and is almost never used in Solo Raid lineups.
Falcon Wings2 triggers at a 10% chance, making her defense inconsistent, and as an R-rarity unit her survival contribution is limited for the investment.

Each time she is hit, there is a low chance her own DEF briefly rises. Using her skill grants her healing based on damage dealt. Her Burst Skill greatly raises her own Max HP.

When her HP drops, cycle healing with Falcon NestB.
Use her Burst to raise Max HP during dangerous sections.
Leaving her on auto by default is fine.

There is little evidence of her being paired in the same squad in the recent meta.

Cover DEF, Damage Taken reduction, and Max HP. If Shotgun accuracy is lacking, pick the Assault Cube. If Harmony Cube levels differ a lot, use the higher-level cube before the ranking.

As an R tank, her Overload priority is low. When investing, prioritize DEF lines; firepower options feel weak.

She sees almost no meta use, so only minimal investment is recommended. When using her, Falcon NestB healing and Falcon Boost1 HP are the goal, so prioritize S2 and the Burst.

A low-tier Defender Nikke. A mass-produced Nikke of the FA line, alongside Soldier OW and Soldier E.G.

Falcon NestB grants her healing based on damage dealt.
Falcon Boost1 greatly raises her Max HP.

Falcon Wings2 triggers at a 10% chance, so her DEF buff is inconsistent.
She has no taunt, so she cannot lock enemy aggro.
As an R-rarity, low-performance unit, she has little value compared to current meta tanks.

A mass-produced FA model belonging to Replace.
