ABILITIES

Inaros Prime

PASSIVE When Inaros takes lethal damage, he entombs himself in a sarcophagus and incarnates as sand to attack enemies, draining their lifeforce to revive himself.

1

Desiccation

Desiccation

Blast enemies with a wave of cursed sand that blinds them and steals their health.

2

Sandstorm

Sandstorm

Become a sandstorm. Inaros devours enemies pulled into his whirlwind, healing himself.

3

Scarab Shell

Scarab Shell

Activate to form Armor by draining Inaros's Health. Activate again to stop the formation early. The protective layer reduces incoming Damage and absorbs Status Effects.

4

Scarab Swarm

Scarab Swarm

Summon a Scarab Swarm to attack enemies with guaranteed Corrosive Status. Damage scales with Inaros's Health. Enemies killed while immersed in the swarm summon a Swarm Kavat that fights alongside Inaros and guides the scarabs to other enemies.

CEPHALON FIELD GUIDE

How to play this build.

Tenno. You need 8334 health so that the 6% health regen lands at 500 per second, which exactly cancels Arcane Persistence's loss rate. Past that number Inaros simply does not die.

How it works

The whole build exists to clear the 8334-health line where 6% regen matches Persistence's 500 per second drain.

Above 700 armour, Persistence caps incoming health loss, so the two rates cancel and you are effectively unkillable while AFK.

Elemental Sandstorm plus a statstick gives it something to kill with.

Helminth

Elemental Sandstorm over the first ability for the passive damage.

Where it struggles

Zero mobility identity, slow kills, useless against nullifiers.

It is a camping tool.

Variants

The Undying (#064) is the active Inaros; The Grinding Storm (#141) is the Sandstorm nuke.

Who runs this

Players parking on a Steel Path Survival life-support for hours.
