No seriously, where in the fuck is G&K getting these? Most people are familiar with this only because it's gotten brought up by Forgotten Weapons and C&Rsenal. Anyway, she's a funny damage SMG in that instead of contributing to damage herself, she makes others hurt shit more. Potentially OK for boss fights (where she can give you a 34% damage increase after a few seconds), but there's very few practical enemy types you'll be shooting for long enough that it'll really be noticeable outside of that.
