Supernova is a shotgun pretending to be a handgun to go along with her shipmate GSh-18. She’s one of the most supportive shotguns available and she enables some real dumb stuff. You want to use MGs at night? Well, her skill allows for that. Do you need a little more defensive capability for your shotguns? She brings that too, all in a kancolle-flavoured package. Honestly, she’s not an automatic pick on every team. You’re likely going to have to drop a MG in your formation to make use of her fully, which can be an issue.

Her two main draws are her movement speed and her MG buffs. Her roller skates allow her to go almost as fast as a handgun, but not quite. Not much else to say about that, but main reason to take her is the MG buffs she provides.

While crit rate is nice, the accuracy buff she provides to MGs is fixed. This means that MGs are entirely usable at night. It bypasses the accuracy penalty that you would normally have with no PEQ. While not the most relevant thing currently, you definitely want to have Supernova in your back pocket for the future.

3* Ribey.

The problem is Ribey herself is only borderline viable to begin with; she has some of the lowest DPS of any AR herself and almost completely relies on her buffs to make up for it, which usually works out to a net positive, but not always.

Vepr has both weaker stats and weaker buffs (both skill and tiles), and you won't get dupes of her. Really no point in bothering with her, the free SAA you get from career quests or any 4+ star AR will give better results.

"Yay, we can all clear singularity now!" Oh wait... :V Fucking Ceia, I swear...

Yeah, she's a little over-hyped, but she's actually a fairly solid unit. A stacking buff every few seconds? Not bad at all. This allows her to buff firepower, accuracy and rate of fire all at once. Her main issue is it takes a few seconds for her skills to REALLY kick in, but she's great for the longer fights that start creeping up here and there, and for things like backing up M4 in her railgun mode. Not super necessary compared to before now that we have lots of buffing HGs, but she's handy for things like ranking maps.

Another fun thing about this mod you might not know is that the passive 2nd skill automatically activates on a cooldown that you can't see, so rifle tile buffs (which speed up handgun cooldowns) make this activate faster.

Her Mod 3 equipment is kinda pointless for her role, though, so unless you like the art or have bad OCD, she's fine at Mod 2.

Yes I know that's not really her name. And yes, you'd think the unit whose hands are actual guns would be a handgun, but nope, she's an SMG. MICAAAAAAAA.

She has a pretty interesting skill that reminds some of C-MS. What it is is mildly more complicated, because it comes with good AND bad sides, and allows her to be both a main tank and an off tank. As an off tank, she provides decent firepower with 100% uptime, a debuff no one cares about (-acc) and a really nice buff (constant eva up!) for the main tank, while as a main tank she has permanent Eva up, buffs acc of the same column ("vertical row") but actually makes the off tanks (or just people in the same column) a little less survivable. Skill discussed in more detail in her entry, but its fun stuff.

A problem she has though is the shape of the tiles. That lacking middle row really gets in the way, but she has enough other uses that this isn't too awful if you know what you're doing (For example, you want to buff the everloving bajeezus out of your main tank's dodge instead).

Also she buffs Rifles with her tiles too too, but this doesn't seem to come up all that much.

Her damage buff is respectable for a 3* handgun, her tile layout… not so much. The X layout will typically make her excel in a 2SG2MG1HG setup. That setup is very niche and won't come up often. Outside of that, her buff tiles force her into a forward position as main or off tank. She's absolutely not suited for this with her poor HP and evade, and her buffs aren't good enough to really justify it mostly. If youre running and RF HG, you want Calico there usually.
