This build uses [Vicious Spread] to increase the range of the [Phantasma]'s bullet spread. I got the idea from looking at other people's builds and seeing complaints about running out of ammo because a faster fire rate kills the enemies too fast for the status procs.

So why don't we just miss the enemy and hit everything in front of us like a cone?

[Galvanized Acceleration] to hit everything from further away too
[Primed Ammo Stock] and [Shotgun Barrage] for better sustained and burst dps
Viral and heat because I've tried electric and it sucks on the steel path compared to heat
Primary merciless cause we ain't gonna be aiming much and the reload speed increases sustained dps

I tested this build in steel path Mot without roar or other weapons. 400 kills in 5 minutes which isn't amazing but I wasn't using any abilities other than warding halo (Tested with [Nezha] not [Revenant])

How to play the build?
Don't aim because that will increase your accuracy {unless single target}
Get enemy health bars down 2/3 of the way then let the status effects take them out. You do not have to keep shooting to kill them just 1 tick of damage will do it and when enemies are on fire they don't attack you anyways.

This build is not for eximus or acolytes I strongly suggest using a [Laetum] or other single target secondary. This is basically a [Kuva Nukor] as a primary
