Remember to double jump/bullet jump prior to using. That 387% status chance will become 477% status chance, allowing you to get absurd amounts of status procced. If you feel the statuses don't last long enough, switch Vigilante Armaments for Lingering Torment or Hunter Track. If you'd like min-max your status chance, replace Toxic Barrage with [Nano-Applicator] and just get used to having to use an ability, double jump, and aim prior to being allowed to even touch this weapon. Doing would allow you to get 504% status chance, ensuring you get 5 status procs per projectile.
