Introduction
This [Inaros] build is solely focused on staying alive. Arcane [Guardian] almost doubles his EHP when active and Grace adds a ton of regeneration, allowing you to tank enemies without worrying about dying. Negation Swarm allows you to ignore all Status Procs, which includes Knockdown - a huge boon that makes Inaros even more resilient against enemies.

If you use a melee-focused playstyle, consider using [Swift Momentum] or [Melee Guidance] to free up a slot on your Melee weapon. This is especially effective on [Inaros] as he naturally uses two Gladiator Set Mods, allowing you to get an additional +50% Critical Chance on your Melee when using a stat stick Deconstructor.

While the build uses Corrosive Projection for the flexibility of a dash polarity and in-game usage, if you want to have the highest EHP to flex on poor people you can run [Physique] + [Coaction Drift] instead. Consider using an Aura Forma on this Warframe if you want to swap between these Aura choices.

You can also replace Arcane Grace for an Arcane of your choosing, like Arcane Avenger or Arcane Strike, if you run Magus Repair on your operator or if you heal through [Inaros]’ 2 or passive. This makes for a more active playstyle, so I recommend using Arcane Grace for most players as you can lazy tank everything.

[Vigilante Pursuit] is my Exilus Mod of choice due to its utility and the bonus damage from its set effect. Feel free to replace this mod with your preferred Exilus Mod.

We don't use [Health Conversion] because Health Orbs are hard to come by naturally without the use of Warframe Abilities or the Synth Set Mods. Additionally, [Health Conversion] stacks expire when you are shot. If you do want to use [Health Conversion], replace [Gladiator Aegis].

Arbitrations: [Inaros] is a great frame to use when you get started in Arbitrations as you don't have to worry about dying. Be sure not to lean into his tankiness too much, or you will have to unlearn a lot of behaviors that will get you killed quickly when you play other roles.

Hijack: [Inaros] is the best frame to AFK Sortie or Kuva Lich Hijack. Simply hop on the objective and ride it to the payload.
