Toxic to the core, Nox lobs exploding poison goo at enemies. Rupture his helmet to expose his head but beware of the unleashed noxious gasses.

The Nox is a type of Grineer "Chem Strike" unit. They wield a poison-filled heavy gun that shoots blobs of toxic sludge which stick to targets and surfaces before exploding. Bloated and disfigured by the very chemicals they wield in combat, these vicious warriors wear crude, heavily armored suits that both protect them and serve to contain the noxious clouds they emit. Breaking the glass cover protecting their heads both releases this poisonous aura and exposes them to headshots. Beware of their final moments however, as they explode into a lethal cloud upon death.


  • The Nox wields what is effectively a primary version of the GrineerCrossbowGooGun.png Stug. As such, its projectiles have a low range and arc, which causes the Nox to have difficulty targeting his enemies from range.
  • To counter its ineffectiveness at range, the Nox can charge forward, causing all in his path to be knocked down as well as allowing him to close the distance for his gun to be more effective. They only do this as a last resort, however, once their glass helmets are destroyed.
  • Combined with the ability to emit a constant 3-m aura of DmgToxinSmall64.png Toxin damage when the helmet is broken, the charge allows the Nox to knock down Tenno, then deal damage directly to their health.

Damage Resistance[]

A Nox's armored suit possesses DR that scales depending on your weapon's DPS, where DPS is calculated by

This DR also applies to its head so long as the glass is intact.

Once the glass is broken, the head uses the following system:


  • The Nox's projectiles can stick to the player and inflict a slowing effect, similar to a DmgColdSmall64.png Cold status effect, though less severe. The sludge can be shaken off by rolling.
  • Despite his head being exposed when his glass helmet is broken, his scaling damage reduction will still apply.
    • Damage reduction includes DmgTrueSmall64.png True damage type, thus making Noxes resistant to otherwise deadly stealth take-downs.
      • Percentage damage dealt by Reave130xDark.png Reave is significantly reduced.
  • At base level, the Nox's projectiles on impact deal 20 DmgImpactSmall64.png Impact and 3 DmgToxinSmall64.png Toxin damage every second. Explosions deal DmgImpactSmall64.png Impact 30 damage.

Affinity ???
  • Possesses an innate 20% damage reduction.


  • Breaking the glass helmet will allow headshots and normal damage, but allows the Nox to emit a constant aura of Toxic damage, similar to an older incarnation of the Toxic Ancient.


  • The name is a shortened version of Noxious, meaning poisonous or very unpleasant.
  • The Grineer letters on its shoulders say "Noks" and the letters on its gun say "goo".
  • The Soaktron from the Dog Days Tactical Alert appears to be based on the Nox's weapon, with the notable difference of being filled with water instead of deadly poison.


  • A MindControl130xDark.png Mind Controlled Nox will still hurt players with his toxic cloud when his helmet is broken.
  • The goo stuck to the players will still slow them even if it's from a friendly Nox (such as the allied ones from an invasion).
