A ridiculously overpowered handgun in the right hands. If you know what you're doing, she is absolutely bonkers. Led to a meme on older servers where "the practical number of RF teams you could field was equal to your sets of Px4 and Five-seveN."

Strictly speaking it isn't true, but it gives you an idea of how valued she is. What she does with her active skill (at lvl10) is reduce crit rate by 20%, but increase your crit damage multiplier by 50% for all dolls in her tiles. Considering that crit damage STARTS at 150%, and that its tile based, which means you can engage in tile fuckery (which makes these effects stack MULTIPLICATIVELY), and there you go. For RFs, with a +10 Gold Scope and 5-7, they maintain 100% crit rate through all this. For ARs, you need to worry about the math a bit more, but it is generally an overall increase unless your critscopes suck.

Works with TAC-50, which is part of why she was so hideously overpowered.

Aka 64 Shiki if you're a weeb.

She's a bit of a complicated unit in that certain enemy thresholds alter what her skill does, thus making her work better vs bosses (with her colossal 90% FP boost for a few seconds) than for regular encounters. However, the timings are awkwardly short for the big boost, and the 2nd half reduces her firepower a bunch but also buffs the hell out of the stuff in front (which, if it's SR3, means more damage for her.) Note that the skill is less awkward than it seems, as it counts doll groups, rather than individuals, so 5x 5-linked enemies is totally fine, and so on.

Unfortunately, they removed cool tile buff tricks so her potential of giving insane buffs is a lot more limited than before

Thot twin #3?!

And probably the one that's going to give me a fucking heart attack. Yes, her skill has big numbers. Biiiiig nuuuuuuumbers. Now get your dick off your phone screen and start using your brain:

• If she does not use her active, she slowly gains evasion over time. Emphasis on slowly.
• If she does use her active, her evasion slowly drops down to "nonexistent", making her a sitting duck if she's tanking.

In a proper tanking role, her buff tiles are literally useless: 500% crit buff x 5% SMG base crit rate = 30% crit rate if you aren't running a suppressor or a crit scope, and if you are using those, your SMGs will have shit-tier accuracy even if you stack reasonable amounts of buffs on them. At the same time you're losing out on AR buffs, which will extremely cripple your DPS. You're better off bringing C-MS or RO635 to buff your back line instead. Even Suomi can buff her evasion up faster than UMP40 could ever hope to.

If she does use her active skill, it'll similarly take incredibly long for her to really ramp up her damage skill – at 18+ seconds to get her damage above 2* ARs, she competes with Negev for the title of "slowest stacking skill in the game", and SR-3MP consistently out-DPSes her even without any buffs. With the UMPs' exclusive equip. Without, her damage output is even worse.

You can build some silly 5 SMG meme echelons around her that sometimes don't totally suck, but unless you know what you're doing, you should put her on cafe duty.

Selfie Queen. Troll. Probably Jarv's waifu Jarv in disguise. Claims bullpups are scientifically the best thing ever.

If she doesn't have an ally in front of her, she self-buffs for both firepower and RoF, with a net increase of 76.9% DPS (over G41's 75%, and she has more base firepower, so she will provide generally superior damage except vs armor). This alone makes her usable, but her unique brand of cheese is when you have friends in front of her.

On skilluse, she scans for an ally directly ahead and if one is found, gives them a 40hp shield that increases their evade by 80%, stacking multiplicatively with all other buffs. Has very good synergy with units like C-MS, MP7, and the like. Due to the way area scan skills work, with the move command and a sense of timing, you can actually protect the whole echelon this way via shenanigans (or at least just all your frontal tank units). Oh by the way, this also works on the taunt fairy target drone.

Flexible unit that can be used 2 ways, and is actually handy in both of them. Her problem is really less how good she is as much as the game has actively been dumbed down to the point there's basically almost zero need to move units around anymore outside of a few boss mechanics. Or some gigabrain strats that if you know...why are you here?
