When it comes to the mod loadout it is important to remember that a weapon should suit your playstyle.

There are many [Xaku] builds out there for end game content and this is pretty much the same; use The Lost: Gaze and strip armour.

Energy Siphon is used but you can swap it out for Shield Disruption- to make Corpus enemies slightly easier. [Corrosive Projection] can be used if your loadout has slightly less power strength.

Blind Rage can be replaced with Transient Fortitude and the *Umbral Intensify replaced with a regular Intensify/[Augur Secrets]. If you have less power strength [Corrosive Projection]** can help pick up that lost strength.

This is an energy hungry build and uses Arcane Energize. If you don't have Arcane Energize you can use energy pizzas or simply kill fast enough to where energy dropped can make up for the energy used.

I don't really use this build in Steel Path missions but I hope it gives players a little wiggle room for mod configs.

My general use config [Xaku] that I do use for Steel Path here.

Happy Hunting.
