This is a monster secondary, one of the best in the game currently.
Overframe does not show the stats of quick shot fires but it has 50% base status chance, a guaranteed aoe cold proc and a guaranteed impact proc on direct hits. As well as the explosion having innate blast damage. With three status mods it has a 180% status chance per projectile.
With all the buffs up you're be applying 15+ status procs per hit, a mix of IPS, viral, heat, cold and blast. This leads to absurd damage and a 70% chance to apply big slash procs on direct hits
The faction mod is overkill but it is a seperate multiplier to all the % damage we are stacking. Really though, outside of steel path it's completely unnecessary, you could go with [Primed Fulmination] for bigger aoe.
Oh and the charged shot is still very strong if you need a bit of extra damage on status'd up single targets, distant targets or just to get your galvinzed mods up and running.
