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.

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.

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.
