This entire build revolves around subsuming [Grendel]'s Nourish over Axios Javelin to allow us to generate an astronomical amount of energy in conjunction with Rally Point. This makes Stanax the best Railjack Pilot in the game right now since he can spam Battle Mod armaments, which cost a lot of energy, at an unrivaled pace as well as being an S tier frame that can easily handle away crew duties when playing solo. This setup also allows us to spam cast Final Stand and generate overguard on each hit, which makes [Styanax] practically unkillable.
His survivability, ability to generate massive amounts of energy for yourself and your whole squad, ability to easily deal with crowds (with a armor-ignoring slash based, AOE, high damage ability which can also proc Viral status with Nourish), and ability to strip with Tharros Strike makes him an all around top tier frame for all content and one of the most comfortable frames for Disruption.

Notes:

Not Recommended to go below 190% range
For Duviri/Circuit: more range is preferable to more strength, ideally at least 235%
For Disruption: Recommended to run Enemy Radar+Enemy Sense/Vigilante Pursuit for max radar.

Swap Augur Secrets and/or Augur Message with Stretch then Augur Reach for more range.

Cunning Drift for more range can be used over Power Drift or Vigilante Pursuit over Power Drift for easier targeting with Final Stand

Primed Flow is very comfortable and gives you more flexibility around when you can recast Nourish and Rally Point and lets you spam [Seeker] Volley and Shatter Burst more when piloting a Railjack, but could be swapped for Stretch

Intrepid Stand is mandatory and means we don't have to run Adaptaion or Prime Sure Footed anymore because we get overguard on hit with Final Stand.

Aura is completely flexible.

• Energy Siphon provides a nice baseline of 1.9-2.3 energy per second as you gain Molt Augmented Stacks while Nourish is up.
• Enemy Radar is good for easier targeting of Final Stand into groups of enemies and for sighting Demos in Disruption from further away.
• Corrosive Projection is unnecessary because Final Stand deals slash damage that ignores armor, and we can strip with Tharros Strike when using a weapon.

Molt Efficiency is flexible but very comfortable for free duration since our shields should always be active with overguard from Intrepid Stand.
Arcane Arachne can provide more damage to Final Stand.
The Combat Discipline + Arcane Avenger combination does not work because Final Stand is unable to crit.
