Fire, ice, electricity, or poison: choose an element and launch a flurry of deadly quills. This versatile sidearm is Khora's signature weapon.

The Hystrix is KhoraIcon272 Khora's signature sidearm that fires metallic quills. Sporting a high critical chance, it is also a very versatile weapon, with its quills applying Toxin b Toxin, Heat b Heat, Electricity b Electricity, or Cold b Cold elemental status procs that can be cycled at will with Alternate Fire.

  • Using the Alternate Fire button will cycle between the four quill types, each quill characterized by the four main elements (Toxin b Toxin, Heat b Heat, Electricity b Electricity, Cold b Cold). The selected quill has a guaranteed chance to proc the element of its name. For example, the Poison Quill will deal 36.1 base physical damage and proc Toxin b Toxin.
  • The Hystrix by default does not deal any elemental damage, only elemental procs.
  • Quill elements are not affected by elemental mods of different elements. For example, using Mod TT 20pxJolt with the Fire Quill will not combine to either deal Radiation b Radiation damage or a Radiation proc, even when both the Heat b Heat and Electricity b Electricity procs occur simultaneously.
    • However, elemental mods of the same type will combine. For example, using Mod TT 20pxScorch with the Fire Quill will add to the guaranteed Heat b Heat proc's damage over time as if Scorch were a base damage mod.
      • Elemental mods of the same type will still combine even when paired with a different elemental mod too. For example, using Mod TT 20pxScorch and Mod TT 20pxJolt with the Fire Quill will add to the guaranteed Heat b Heat proc's damage over time as if Scorch were a base damage mod, though Jolt will not be factored into the damage.


  • Because elemental mods are not combined with the quill's element, this weapon synergizes well with Mod TT 20pxCondition Overload, allowing players to potentially get up to 9 separate proc types on a target (three physical damages, four primary elements, and two secondary elements).
    • This can be further improved by incorporating elemental weapons like a SundialAxe Zenistar's disc, or GrineerGrenadeLauncher Torid's gas clouds to provide the remaining secondary elements.
  • Dual wielding the weapon with a Condition Overload-equipped Glaive is an effective method to take advantage of the Hystrix.
  • Using Mod TT 20pxAugur Pact over any of the +90% elemental mods may be preferable, when expecting to use several of the weapon's elemental effects.
    • The former will increase the weapon's physical base damage types, and the damage-over-time component of its Toxin b Toxin, Heat b Heat or Electricity b Electricity status effects.
    • The latter will add its elemental damage type to all hits, but any damage-over-time effects from the primary elemental procs, will only be boosted when they match the elemental mod's type.
    • It should be noted that, while the bonus given by both mods seems the same, the elemental damage mods will give much more benefit, as Augur Pact does the calculation alongside base damage mods (e.g. Mod TT 20pxHornet Strike), while the +90% elemental mods perform the calculation after base damage mods. This can be a significant deciding factor when trying to maximize damage output.
