This build comes from the [Sevagoth] Steel Path Youtube video that can be found here. The main difference is that I've replaced Arcane Energise with Arcane Grace, as well as [Power Drift] with [Cunning Drift] in the Exilus slot, since I find I don't need the additional strength, and duration is just great to have. I've also fitted a [Primed Flow] instead of the duplicate [Primed Continuity] that was in the video's build.
You'll need an Aura Forma to make this build work, as well as a forma for the Exilus slot and 4 more for the standard mods. That makes 1 Aura Forma + 5 Forma total.
I designed this build for my personal reference. Do let me know if there's anything you've found to be more useful in your builds!
