Playstyle

Scarab Shell is the identity — charge armor, absorb Magnetic/Heat/Corrosive, Negation Armor for fatal hits. Guns or Sandstorm for clear.

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.
  • Keep Scarab Shell. Negation Armor recommended. Adaptation + health stack.
