Arsenal

Playstyle

Stack armor for Arcane Persistence (Scarab Shell + Guardian / Umbral Fiber / shards), keep Shell charged, Negation Armor for fatal hits. Sandstorm heals between pulls.

Passive abilities

Inaros has no shields — massive health and armor do the tanking. Finishers and Sandstorm heal; Scarab Shell adds armor and status absorb. Arcane Persistence pairs extremely well once armor is high enough.

Active abilities

  • 1 Desiccation — Blind wave that steals health and opens finishers. Desiccation's Curse spawns Swarm Kavats on finisher kills.
  • 2 Sandstorm — Become a healing tornado. Elemental Sandstorm primes from your melee elements.
  • 3 Scarab Shell — Spend health to build armor and absorb statuses. Negation Armor is a cheat-death on fatal hits.
  • 4 Scarab Swarm — Corrosive scarabs that scale with health; kills can spawn Swarm Kavats.
  • Augment: Negation Armor on Scarab Shell. Arcane Persistence is the modern backbone.

Mission Usefulness

  • Steel Path Survival / Defense / Disruption

    Excellent

    Arcane Persistence + Scarab Shell armor makes Inaros nearly immortal on SP endurance; Negation Armor is the panic button.

  • Mobile Defense / Excavation

    Excellent

    Stand on the point under Persistence caps.

  • Exterminate / Capture Speed Runs

    Situational

    Tank comfort; clear speed depends on Sandstorm / guns.

  • Spy / Rescue / Nightmare

    Weak

    Loud desert tank — not stealth.

  • Open World / Bounties

    Strong

    Hard to kill on bounty camps.

  • Long-Range Gunplay / Eidolon-Style Content

    Situational

    Survives hunts; not an Amp specialist.
