Welcome to the next installment of [Shattering Impact] + Bad Weapon = Mid weapon. I'll be your host.

[Vermillion Storm]'s forward combo has 16 hits. This is enough to make [Shattering Impact] (the best melee mod ever) viable.

[Amalgam Ripkas True Steel] is cool as hell and synergizes with shotguns. Rip and tear.

[Weeping Wounds] and [Blood Rush] are like that cute couple the keep checking out out from across the room. This is good.

Attack speed is important for [Shattering Impact] procs. Consider ditching [Amalgam Ripkas True Steel] for [Gladiator Vice] if you're no fun.

Toxin and Radiation are two easy status procs and gives you options against shields. [Carnis Mandible] is good and can replace [Focus Radon] here, but that'll be one less stack of [Condition Overload] and claw heavy attacks have guaranteed status anyway.

Get a Riven mod dirt cheap with basically anything passable and you can slot that in over [Focus Radon].

Ok, that's it. Go home. If you wanna farm with these, just minmax into heavy attacks, there's already a good guide on that here.
