Overview

Fedorov, a 4 star Russian cutie, brings to the table an unusual Skill. With an ICD of Zero, she starts ahead of almost all ARs, but fails miserably to keep up with them.

Her Skill kit is rather simple to understand: Every 4 to 5 seconds (depending on if she receives a buff during the Skill’s activation), she buffs additively 10% Damage, up to 6 times. This Skill can be looked at through three lenses:

1. Damage Self-buff: at the last buff, she’ll have a 60% Damage buff (at 20-24 seconds, depending on how many times she is buffed). While on paper this sounds good, G41, which is the AR standard, self-buffs 75% at 4 seconds, while at that moment Fedorov will start buffing herself 20%. So against dedicated Damage self-buffers, she lags heavily behind.
2. RoF Self-buff: she starts self-buffing RoF (That is that the “Attack Speed” in the obviously Google Translated Skill description means) 15% from the third buff onwards. That means that she reaches up to 60% RoF self-buff. As she has a base RoF stat of 59, with the #2 Processor equipped, she bumps it up to 84, which will require ~40% RoF buff to reach the RoF cap. That means that, on the third time she self-buffs her RoF, she hit RoF cap, and the fourth buff is entirely wasted. That’s without considering the potential RoF buffs of SMGs in the team (for example, if RO635 is in the team, she already reaches cap on the second time she self-buffs). Against dedicated RoF self-buffers, like Type 97 and Type 89, she also lags behind, as those have much shorter ICDs
3. Accuracy Self-buff: At the fifth buff, she start self-buffing Accuracy, reaching up to 60% Accuracy self-buff. Not only does she have a decent base Accuracy of 60, but she’s also likely to have it buffed via Fairy Auras or SMGs. Moreover, ARs aren’t usually fielded against very evasive enemies that would require buffing her Accuracy to over 100.

All these buffs are permanent, which means that, at the 20-24 seconds mark, she has a permanent 60% Damage, 60% RoF and 60% Accuracy self-buffs. Her passive can also be trigged by Fairy Talent, but not by her own Active Skill too. However, do note that, by this mark, Fedorov still has to catch up, total damage-wise, which means she'll only have a considerable total damage output way past the 24 seconds mark.

Overall, she fails to stand up against decided FP buffers, against RoF self-buffers, and against hybrids buffers, such as AK-12, which also dislikes the #2 Processor due to easily overcapping RoF. While she is prone to overlapping by a fair margin when equipped with #2 Processor, she still prefers the equip over an X exo when fielded with fairies with sufficiently high Crit Damage aura, such as Command, Beach, Parachute and Taunt.

One niche that she could be fitted at is Boss fights, as those are notorious to last well past the 24 seconds mark. In those, Fedorov’s permanent buffing (which is a decent 60% FP and RoF buff) would let her catch up to other ARs’ total DPS, and even surpass them. However, because Boss fights are very niche in nature, and often require specialized teams, there’s the possibility that she won’t have room to shine when the likes of G11 Mod and ST AR-15 Mod exist. Therefore, fitting her on Bossing teams should be looked at on a case-by-case basis.
