Status chance is king on this build. An argument can be made for switching [Anemic Agility] for [Saxum Spittle]. Based on my math, a 50% relative increase in fire rate compared to a ~15% relative increase in status (even with a 4x multishot) is a minimal adjustment. Obviously, stat increases to attack speed like [Gauss] or [Wisp] change how applicable that change is.
This build can also work with Cascadia Flare as well. That would best be reflected by a build utilizing crit, however. And thus is not this build.
Galvinized Shot is used more for it's status chance than it's damage applications, but do be aware that switching [Embedded Catalyzer] and [Anemic Agility] with [Hemorrhage] and [Saxum Spittle] would work to scale both the damage of [Galvanized Shot] and of the weapon as a whole.
Some testing still needs to be done to figure out which is best in slot. Alongside a subsumed Breach Surge, more status feels better for the skill.
