2B is both a sword and a shield. Why choose between offensive and defensive when you can be both at the same time? In short, 2B is what Crow wishes to be, but she can't because of unknown reasons. She boasts a titanic amount of HP and can demolish enemies with ease thanks to her conversion gimmick. Oh, and she is also the unit with the highest real-time attack in Nikke!

Performance Analysis

2B is an offensive defender whose ATK scales off her HP. She has a low basic attack multiplier, and around half of her output is from Burst Skill. While her basic attack multiplier is concerningly low, her burst damage makes up for it, dealing over 3,000% at higher levels provided there is only a single enemy. This makes her quite similar to Maxwell in gameplay, whose damage heavily relies on Burst Skill. Burst damage like this usually benefits a lot from short-term but huge bonuses such as the one given by Novel's Burst Skill.

One special thing to note about 2B is that her offensive strength scales linearly with her HP. This means any MAX HP buffs invoked by herself or other teammates will significantly boost her ATK. However, as a defender, her base ATK stat is poor, which means all buffs that increase ATK based in the target character will be much less effective. Even then, the efficacy of ATK buffs is also inferior to HP buffs, so there is no reason to pair her with ATK-buffing units. Instead, pair her with units that boost her MAX HP instead. Detailed team compositions will be discussed later.

Furthermore, 2B is more suited to longer fights as her damage increases with time. Her S1, which is vital to her output, requires her to burst three times before reaching its max value. This makes her powerful for boss fights but weak in normal stages.


2B relies a lot on her HP stat, which can only be gained from bond levels, equipment upgrades, limit breaks, and skill buffs. She scales extremely well with skill upgrades too, which must be prioritized.

For equipment, we recommend overloading her Body and maxing its level. This piece of gear provides a tremendous amount of HP. Her helmet and boots can also be upgraded, but these are less rewarding. To conserve materials, you can leave her Helmet and Boots at level 2 or 3 once overloaded.

What about OL? As a defender, 2B has a low base attack value, which means she benefits less from OL lines and buffs that increase ATK based on the target character (Noir is an exception). Furthermore, she alone already acquires too much attack from her S2, making attack buffs much less effective. Nevertheless, she still benefits from Elemental Damage, and critical hits can also help multiply her already insane damage. Hit Rate can allow her to hit enemy's core more conveniently, but since most of her damage is contained within her burst, it is probably not that valuable.

While rerolling, keep in mind that ATK lines are less favorable for 2B, although they do boost her output a little. It is recommended to obtain Elemental DMG instead or situationally CRIT and Hit Rate. However, if you are tight on rocks, feel free to keep your ATK rolls (though you need to max her Head and Gloves for them to be more relevant).

As for Skill Levels, we recommend prioritizing her S2, the core of her kit. You MUST level it up to 10 as soon as possible, else she will not be able to perform well. After that, you may choose to upgrade her S1 to increase her MAX HP, which in turn boosts her ATK. Or, you can upgrade her Burst to increase her overall DPS. For people with tight budgets, I recommend leaving her S1 and Burst at 5 respectively to save up Blue Manuals. That being said, upgrading her Burst is more important than her S1, as her Max HP can also be boosted with the help of other units, including but not limited to Noise, Mast, Frima, Quency, Rapunzel, and SMary.

Use 5-10-5 as a starting point, then develop your 2B based on the number of materials you have. Prioritize Burst upgrades but keep in mind that A2 will be coming soon too, and she wants you to save some for her.

Team Compositions

As mentioned earlier, 2B is about MAX HP buffs. Fortunately, some other buffs and debuffs can also benefit her without any dilution/degradation, such as Damage Taken and CRIT. Meanwhile, ATK is significantly diluted, so it is inferior. Part Damage is a big no because her burst damage does NOT aim for parts. Keep this in mind when you are forming your team. Prioritize MAX HP, Damage Taken, and CRIT if available! We are not sure whether it is a bug or not, but Jackal's Burst Skill also buffs 2B's entire Burst damage (both instances).

PVP Usage

The new hotshot in Arena, 2B has graciously landed to mercilessly slice the enemy team clean. While she may not be meta-defining, she is one of the best DPS out there. Remember Scarlet? She is similar, just slightly weaker as she relies on support units. Unlike Scarlet who sharpens her blade with ATK buffs, 2B needs to fortify herself to prepare for an unforgiving strike. She must be paired with units that grant her MAX HP in order for her to turn the tide, such as Noise, Mast, and Blanc. Jackal also has a special connection with her, as she gives her burst an independent damage multiplier.

While Blanc is a general debuffer, she also gives MAX HP to lowest-HP unit, so if your 2B's HP is low enough, Blanc will turn her into a beast!

One advantage 2B has over Scarlet is that she is a defender, so she can make use of Biscuit's immunity to protect herself from an otherwise fatal hit. Use this to your advantage and craft creative teams to overwhelm your opponents!

To use 2B in PvP, you need to invest in her Burst Skill. Note that her burst consists of two instances: one is split among 5 units, and the last one to the highest HP enemy. She can be a great sniper!

Pros & Cons

  • 2B is mathematically the highest-attack unit in the game.

  • 2B is the only unit whose DPS increases with MAX HP buffs, so she does not steal most other DPS' support units.

  • Limit Breaks are super valuable. They not only buff her base ATK (even if it is trivial) but also her HP (which means more ATK)!

  • She can absorb tons of damage before dying, even as a damage dealer.

  • Her AoE damage in S2 might sound weak, but as a screen wiper, it does wipe the screen (even against those nasty projectiles).

  • Her Burst Skill is one of the strongest in terms of immediate burst damage.


  • EXPENSIVE. Need high investments. Without investments, she is even worse than most units.

  • Shines only with certain units such as Mast, Noise, Quency, Novel, Frima, Jackal, and SMary since ATK-buffs are less effective on her. Jackal might be a bug.

  • Her damage is low at first but insane as time goes and reaches its peak after activating Burst Skill three times.

  • In some cases, gear upgrades are needed not only on herself but also on supports (Mast, etc). This also includes upgrading those supports' skills to make them more relevant.

  • Limited AND collab unit at the same time, so unless you MLB her now, you will have to wait who knows how long for a rerun.
