Overview
Fedorov is a strange self-buffer.
Fedorov has a short CD Skill that applies a small permanent buff every time it is activated, up to 5 (8 with SPEQ) times and with additional effects being added to the Skill as she activates it more times. Her passive simply does not do enough to even look at twice. All stacks are additive, and at 8 stacks she will have 80% Damage, 90% Rate of Fire and 120% Accuracy. Note that it will take around 30s to gain all 8 stacks, and even longer for her to catch up in damage dealt.
While her final buffs are certainly good, they come in so late and her performance up to this point is far too unimpressive for any realistic use. When you compare her to good AR Mods and Set Dolls, she will need over a minute to catch up to their damage dealt, which is just way too slow.
Immunity to damage for 5 seconds with a 30+s ICD is just NOT useful. This effect is absolutely terrible.
Note that for some reason, Fedorov’s Skill is set to Forced Manual by default, and there is absolutely no reason for this. If you decide to use her, make sure to turn this setting off.
All in all, Fedorov is not recommended for use.
