The [Amprex] can be a status monster, a crit monster, or both, but who needs status when your target is dead?

[Vigilante Supplies] is a QOL mod and can be dropped to save an exilus adapter and a forma.

[Infected Clip] can be substituted for [Malignant Force] if you want more status, but it's a DPS loss.

A Riven should replace [Primed Shred], but you'll likely need to drop [Vigilante Supplies] to run one. You're looking for crit chance, crit damage, multishot, and punch through in that order.
