Ablative armor and a grenade. Has a lot of HP for her rarity with a not so terrible evade, though YMMV between her and M38. Her main virtue is that she's the first 3 star you get from the story and they give you a pile of her so it's easy to stock up bodies. Only useful for logistics and cores once you have real tanks. If you happen across free PPS-43s, they're somewhat better.

Has a mod, but it's not great either.

If for some reason you want grenade damage, which is mostly an anti-scout thing early on. Honestly cores most of the time, but if you need to blow up scouts on the cheap, she's better at it than Sten at least. Also has better buffs than Sten, but you're more likely to happen across cheap/free Stens than PPSes. If you DO get a pile of her though, she's at least better than Sten.

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.

Not to be confused with PP-19-01. Decent stats, interesting buff tile, but like all grenade SMGs kinda superfluous.

Between Zas (same area, more damage, enemy debuff), molotovs (a lot more damage and damage over time, smaller area), and airstrikes (all the area, more damage) there's plenty of better options to sacrifice your enemies on the altar of Megumin. Can be pressed into service if you're really lacking off tank options, I guess.

Extra notes available.

Quite literally a 4* Vector. Marginally better evasion and HP, marginally worse firepower and molotov multiplier, identical buff tile. But like Vector, she...is unfortunately not particularly relevant anymore.

If for some reason you absolutely must have a 2 star Molotov. You get Skorpion for free really early so she doesn't see much use (though she does slightly outdamage skorpion). Has not great dodge and okay HP. She does however come with an adorable as hell Children's day skin so I wont entirely fault you for wanting to bring it.

An alright firebomber if you don't have Vector, but you won't get a shitton of free copies of her like you do with Skorpion. Slightly but not significantly better than Skorpion at actual firebombing, but has a much much shittier aura. Bullied by a lot of artists for being retarded.

Her mod makes her a lot better, rivaling if not surpassing Vector. Look at that article for more info.

She actually has a decent hybrid skill and statset except she's locked behind LSC and a shit campaign grind so you'll probably have better by the time you can get her.

Lower rarity Vector. Has useful evade. Has shit for HP though and lower atk. Can off-tank alright and her molotov is still good enough to use, but you really want better SMGs. Her primary virtue is that you're given a pile of her at the very start.

The flame witch that destroys all with atomic molotovs. Between a 7x damage explosion and 15x more over 5s as a DoT, she's an acceptable tank but does best as an off-tank and dealing damage. Ideal for clearing scouts and other high-dodge targets in night battles, or eradicating swarms. Pump up her raw damage stat and watch the fun. Not great for direct fire, but the molotov is that strong when leveled.

Unfortunately, later in the game, molotovs fall off pretty hard outside of farming setups. Still pretty worth it if you need a molotov and don't want to pay for Micro Uzi's mod.

Uh.... we came upon a weird timeline wherein frankly, if she had a +FP special item? She'd beat out Vector in a lot of cases. Now she only beats her in many cases and honestly might have more utility.

She learned to be less dumb with her tiles and actually they go BACKWARDS now. Wow. The buff percentages still aren't super impressive but she's no longer a dead slot for buffs. The damage she causes with that second skill? Surprisingly really high, especially in clusters. If lots of enemies are on fire next to each other, then they all affect each other with the burn, which can be really nasty vs some of the later ultra-dense enemy packs.

Aside from that, she's just a Molotov off-tank with an extra nice skill. She doesn't bring anything super new to the table as much as she's the pretty nice version of a dish you thought you'd never like.

She's not sure if she wants to be offensive or defensive, and kinda sucks at both. Her only real purpose for existing is "the story is kinda cute."

Base version isn't great either.

As a grenadier, she's fucking awful. It has less power than most grenades do, which is not helped by her shitty FP stat, and she doesn't even aim at enemies (she aims at points on the ground based on her location). This may or may not have value depending on what weird niche content might come up, but she's definitely not general use material.

For the massive expense of bothering to Mod her and get the second skill to lvl10, you get... a weaker molotov skill than Skorpion's at lvl1. Great?

On one hand, it has the same range as the flashbang grenade. On the other hand you paid the data, exp, and core costs for a Mod. Also, the firebomb goes off the same time as a flashbang, so it's slower than normal molotovs.

Yeah, honestly I forget she even existed.

The main feature of this mod is her multi-shot AoE grenades. Think FAL, basically. Also some buffs. Acceptable performance, but expensive for what she is.
