I want to start by saying that my builds will focus on a weapons character and not the meta, as i feel this makes for more unique and interesting builds, if you agree, maybe check out some of my other builds too! :)
Can replace bane for [Primed Shred] or [Radiated Reload]
Crit delay is not needed, it makes our fire rate annoyingly slow, if it really concerns you, swap to auto and build up 5 puncture procs for 100% cc

Alternate: viral electric hybrid
On the [Fulmin Prime] specifically, a viral electric build is also a viable option due to our increased reload speed and larger battery size. If interested, you can replace the following;
Bane < [Primed Shred]
[Point Strike] < crit delay
[Hunter Munitions] < [Stormbringer]
Merciless < deadhead
If you hit headshots, this build actually offers a higher damage ceiling for the majority of content than [Hunter Munitions] because electricity double dips into headshot multi.
