Rosanna Early Thoughts

Old lady with old gun


Rosanna seems like she jumps people in alleyways. Her kit seems to be PvP orientated with the specialty of taking out 2 attacker units on burst.

Basic Info

  • Skill 2: Capo Dei Capi
  • Burst: Vendetta
  • Rarity: SSR
  • Burst: I
  • Weapon: MG
  • Class: Attacker

Skill 1 – On The Lam

■ Activates after landing 120 normal attack(s). Affects self.

Concealment: Prevents self from being the target of single-target attacks for 10 sec. Loses effect when the caster takes damage.

Critical Damage ▲ 19.34% for 10 sec.

■ Activates after landing 10 normal attack(s). Affects 2 enemy units with the highest ATK.

Dispels 5 buffs. Activates 1 time per battle

Similar to Viper’s concealment skill, enemies will not be able to take her unless she takes damage from AoE sources (Rockets, AoE bursts). This works well in tandem with her burst, as if her initial Concealment from skill 2 expires, it can be easily re-applied.

However the dispel buff might be able to counter jackal teams. “Might”, because we don’t know what buffs can be or can’t be removed. We also do not know if Infinite or “Constant” Applicating buffs can be removed or how it dispels (newest,oldest,etc etc). Such plausible buffs are OL rolls, Hit rate cubes and etc. Rosanna’s skill also starts at removing one buff at level 1, 3 buffs at level 4, 5 buffs at level 7, so depending on how she works, moderate skill investment is needed here.

Side thoughts: Probably can’t use against Noah, as most likely, 10 shots will be fired already before she can get her burst off, Nor removing invulnerability from units such as Makima and Biscuit

Skill 2 – Capo Dei Capi

■ Activates at the start of the battle. Affects self.

Concealment: Prevents self from being the target of single-target attacks for 5 sec. Loses effect when the caster takes damage.

■ Activates when a Nikke is out of action. Affects self.

Frenzy: ATK ▲ 22.61%, stacks up to 10 time(s) and lasts for 30 sec.

Fills Burst Gauge by 36.54%

Very spicy part of her kit. Mostly the “Fills burst guage” and “ATK up” when Nikke’s get out of action (destroyed). A theory of what can happen is foddering one Nikke at the start (level 1 unit) to get burst gen + ATK up on Rosanna, which improves her chances of one-shotting 2 attacker Nikke’s/ Team bursting first.

Burst – Vendetta

■ Affects 2 Attacker enemy unit(s).

Deals 1310.4% of ATK as damage.

■ Affects the same target(s) when in Concealment status.

Deals 561.6% of ATK as additional damage.

the meaty part of her kit, any attacker that gets hit by this will probably explode when Rossana has active concealment. and she targets two too, with ATK% aid from her skill 2. PvP’ers/whalers will most likely want to OL/Raise Rosanna to comfortably one shot units. After the 2 attackers are out, it’s basically a free win.

Note: Do keep in mind that she is a burst 1 unit, so b2 units such as Xanne/ Poli buffs is unable to help guarantee one shot kills, and she will most likely need heavy burst skill investment + OL Equipment.

Possible Use Cases


Oof. No. 40s cooldown, requiring units to die for ATK buff which is temporary, and dispel only activates once per battle. The only way i can see her being viable, is when you have to build an entire team for her, which is still rather unoptimal due to her burst placement.

She might work with pepper since she can increase stacks/refresh stacks via burst and theoretically gain max stacks with rosanna (22% ATK x 10) but there’s no 20s Res units in b2 or b3 slots. which means burst timings will be ruined when running 2-1-2 team if any unit dies.

She may have units that can synergize with her in the future, but as of right now, she simply doesn’t have much use for campaign.


As mentioned above. She has the possibility to snipe two units and (maybe) the ability to counter Jackal teams. Even if she can’t, she may prove useful against team 2 and team 3 comps. she would NOT fare well against Noah teams as her burst would just spit on Rosanna’s face.

As she is burst 1, massive b2 buffers such as poli and Xanne is unable to help her one shot units, and would most likely need heavy investment for that to work, however b3 AoE burst should be able to clean up the leftover HP.

An example team is just a sacrificial b1 slot for headstart on burst gen + ATK stack, Rosanna, Poli , and 2 SG’s

Special Interception

Same reasons stated for campaign usage.

Ending Thoughts

Unfortunately, as of right now, seems to be strictly a PvP unit, with not much use cases anywhere else due to the lack of units that may synergize with her in PvE content.

Perhaps.. They’re hinting champions arena? wink wink nudge nudge

Video Demonstration


  1. It’s funny that the tough looking woman always seem to not perform well in Nikke. Sugar and Guilty might be the only exception.

    • I mean it’s what we call “balancing”.
      If you end up releasing units that keep on powercreeping each other then it just becomes a very stale game.
      I mean yes, this game is horny and that’s how people play it, but every gacha game has some sort of competitiveness to it like rankings (exception for other games like genshin).

      Despite the game not having too much of 4 star rarity/low rarity units, they do have 5 star units that aren’t too powerful and are generally niche to one thing. Which is good and healthy for a gacha game to avoid losing audiences and avoid getting complaints about how new units are always being powercreeped every update or every new release of a character.

      • >avoid getting complaints about how new units are always being powercreeped every update or every new release of a character
        yea now they get complaints about how the new character sucks ass lol
        they cant win the poor bastards

  2. Your reasoning is flawed for special intercept. Granted, I haven’t looked at every single b1 in the game, but most of the ones I’ve seen have been big buffs or mid buffs w/ small-mid damage. This makes Rosanna’s 1000% (1500% if you time it) damage every other burst massive. And if you run her with Noise or bunny twins, she get ample opportunity to use it.

    • While Rosanna is an attacker, a unit like Pepper who has a similar multiplier on her burst will probably outdamage her because she’s not on a 40s cooldown. Even if you have extremely heavy investment into Rosanna, she isn’t going to have the kind of damage output that could justify taking her over a b1 unit that offers more utility (Liter, Volume, Miranda, Pepper, even N102). Rosanna is not a character designed for PvE content, so it’s reasonable that she wouldn’t be strong in special intercept.
