Her skill consists of two parts:

• Make her use rifle targeting (backline priority): Originally, the gimmick was useless. However, now she definitely has a niche considering how often Mica likes to toss in weird enemy formations.
• Buff herself: Her stats are good to begin with, and the buff is beefy – this makes her an excellent AR for all purposes.

Overall solid. If you need her gimmick, she's amazing. If not...well, AR powercreep is real.

She has good stats. But shotgun powercreep is real. Also if you have her, you've been playing a long time. Why don't you have a better shotgun? Huh? Waifu? No, she's shit. Get over it.

On top of that she has a nuke skill that... honestly doesnt usually come up, but when it does, it's pretty much the biggest nuke on a shotgun you get (2 hits for 8x vs primary, 12x area around primary). As a bonus, if the first shot kills the primary, the secondary BOOM changes targets (uses standard grenade targeting). Note that due to her ammo and reload speeds, if you want to fire the first nuke immediately, you will likely need to reload cancel her.

A Britbong copy of Cz-75! ...And kinda weird. She's sort of setup for the 2MG 2SG 1HG thing that doesn't come up much and is defensively oriented, but sometimes it comes up. Just... not on any content currently. Does occasionally see actual use as a result, but she's not going to be your first pick for most jobs.

The problem is that RoF reduction is kinda meh, as while it does reduce enemy DPS, it merely slows down the rate of being shot, as opposed to making shots worse (good for SGs as their armour can more readily absorb it) or less accurate (which helps Eva tanks just not be damaged entirely), making it the weakest of the enemy attack stat debuffs.

She's not really much better than Sten. Only you don't get 3 of her to start with. While she's not really worse, getting only 1 copy + getting her way later than you'd find it useful work against her. Think of it as the difference between getting a slightly better car or a car that is not noticeably worse but you get free insurance with it. Both will be replaced shortly either way unless you really, REALLY, want to play 3 star frontline.

Chinese Makarov clone. Similar job to SPP-1, but less boosting your side's acc and more on lowering the enemy's evade. With fairies now existing she's kinda useless.

Unlike the other shotguns, she's focused on firepower instead, with her skill basically making her go DAKKADAKKADAKKA. You would want an Acc scope on her so she can actually hit anything. Sometimes used in 1SG/1HG/3MG formations to provide MAXIMUM FIREPOWER. Tiles are a little eh for that though. Armour is average.

She's still usable and good enough to deal with older content just fine, but the new shotguns currently available just blow her out of the water so hard. Sad day to be a pizzalion.

That skill happens to be giving your entire front row a 35HP shield, that takes armour into account first. It also has 5/8 uptime. Basically, if your SGs took scratch damage before? They should take literally nil now, unless its a really major fight or you were silly enough to go fight anti-armour enemies.

A worse FAMAS, and a good argument for why collecting trophy rifles isn't worth the effort.

....She has tank stats on a handgun with buff tiles that want her in the back. I'm not entirely sure why anyone thought this was a good idea.

A high class SMG that you get for free (and even better, starts at lvl90 with 5 links when you get her now) providing well balanced stats, and a very powerful tanking skill. -Enemy ATK power (nevermind her own +evade!) that goes off in the first 3 seconds, makes tanking the initial contact much easier, and is usable even from an off-tank position.

Can easily be a main or off-tank, while she combos well with UMP45 defensively, lol in current year you don't even need UMP45 anymore (isn't it sad?). Her main weakness is she has very bad uptime (5/12) compared to some other SMGs, but the quick startup and utility (and the fact most fights are short anyway) make up for it.

Did I mention you get her at lvl90 and 5x linked? That's REALLY helpful if you're starting out. And did I mention she has an insanely broken mod? DEFINITELY pick her up.

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.

Has a kind of an unfocused buffs that... kinda sorta benefit things? She doesn't greatly benefit any lineups, really, and you can get more usable 2 star handguns honestly. Can maybe replace the cat nun in the meme Welrod/Makarov/P7 lineup, but people don't actually use that formation seriously for the most part. Really better off as cores.

Maybe one day she'll have a cool mod.

She's a nonstandout grenadier, and those are basically all meh. Technically she's similar to FNC, except she only comes from events and heavy construction so by the time you get her you will have better ARs.

High end MG with good damage potential. Chance to fire an extra shot with every shot, and that has extra damage and can crit (it's not an autocrit, but can crit, see notes). At lvl10, it's actually very steady. With her unique gear, DPS is still extremely high vs single targets. However now we have bullshit MGs like Kord and the like, and being able to murder multiple enemies per shot is the current hotness for mobclear.

+90% Acc Buff aura at 5-links. Also has a +damage up but that's just icing on the weird, underwater-themed cake. With NV equipment, allows you to completely destroy scouts in night battles if you're actually desperate for that. Normally not a buff I recommend, but she actually gives a lot of it so if you're wanting an actual acc buffer, she'll be 1 of the ones you want. Not as important anymore since there will be other sources of acc boost, but... sometimes you might want something?
