Weapon Loadouts



  • The Javlok's alternate fire throws the weapon itself at the target, inflicting 150 physical damage to the impaled target and 600 area-of-effect Heat b Heat damage to all enemies within the impact radius. It also has Impact b Impact, Puncture b Puncture and Slash b Slash damage on physically hitting enemies, which can proc their respective status effects.
  • The Javlok will remain at the location where it was thrown for ~20 seconds after landing, automatically teleporting to the player after said duration or until the player manually picks the Javlok back up for use again.
    • Throwing the weapon does not consume ammo.
  • The Javlok's alt-fire has a max throwing range of ~50m (though it will be displayed as 47m due to the ~3m the player moves forward when throwing the weapon).
  • Although the alt-fire AoE inflicts Heat b Heat damage, it has a guaranteed knockback effect, staggering all affected enemies for a short time.
  • While the Javlok's secondary fire can be charged while wall-latching or mounting a zipline, the weapon itself will not be thrown until the player dismounts from the wall or zipline, upon which the Javlok will immediately launch.


  • The Javlok pairs well with Ember as her Accelerant ability multiplies the amount of Heat b Heat damage taken by an affected enemy, and the Javlok deals exclusively Heat b Heat damage if left unmodded.
  • Both the primary and alt-fires of the Javlok are can be controlled by Ivara's Navigator.
  • Will hit all enemies currently affected by Vauban's Vortex.


  • When picking back up, it might not auto switch back to the Javlok, forcing the user to switch weapons.
  • Sometimes the Javlok will not be able to be equipped after picking up for a period of time.
  • When thrown, the Javlok returns to its default colors until picked up by the player.
  • In the Simulacrum, throwing the Javlok than changing your primary weapon before it returns will disable your primary weapon until you exit the Simulacrum.


  • The name is a play on "Javelin" and the "Lok" naming scheme which is common to Grineer weapons.
  • The Javlok bears some similarities to Stargate's Ma'Tok staff weapon. Aside from general spear-like design, the two weapons share low rates of fire, considerable firepower, and limited effective range.
