Similar to G41 in performance (actually slightly worse, but not significantly) and the artist just drawing their weird fetishes that land you in jail. She's basically a 5 star equivalent of Tavor sharing the primary weakness of taking 6s to startup instead of 4. The skill is good while active, but YMMV.

Honestly, the issue with any AR outside of the big mod ones, is that they just get gapped so hard unless they have a niche. ART556 does not. So you could use her, but....eh...?

Extra notes available.

On one hand, she's actually not bad in melee. On the other, she suffers from dumb mechanics (like not being able to switch to melee while reloading, which WOULD HAVE BEEN REALLY NICE). She's not terrible at the role of "melee shotgun" (she's actually quite good at it), but the number of situations where you'd actually want a melee shotgun are quite limited.

The Night Empress. Unfortunately, she's been going the way of many a monarch with the lower class overthrowing her. She used to be the last word for night battle ARs, but with AS VAL's mod, she has fallen behind. Turns out, being able to use a crit scope at night is very good. That being said, +200% damage at night is still decent and if you can't afford the mod, she's a good replacement.

Also, while enemy armor stacks superhard now, it's actually fine if you have sufficient +FP on your ARs to punch through. If you don't though, this still wont save you.

No, she's not a video tape. One of her skins shows her recent arrival in the US has apparently given her quite the dump truck ass. Must be all the McDonalds. Her skill powers her up with extra stats relative to the enemies she's fighting, meaning she has basically no real use vs. mooks. Potentially handy vs. bosses, but being a RoF-focused AR, she suffers from chips existing.

Suffers from there being a more famous, better M82, also with pink hair.

This one is basically interchangeable with Tavor, who by now isn't nearly as useful because you should be drowning in high-end ARs. If you are not drowning in high-end ARs for some unfathomable reason, well, she isn't the worst thing ever.

Also has a combo skill with AK Alfa if you do the side story stuff, but AK Alfa isn't exactly wowing the charts either.
