But don't worry, the admin and editor team are aware of them and they will be resolved over the next few days as our Weapons Module goes through a much needed overhaul.
Sorry for any inconvenience!

Brain-strikes excite this bioweapon, causing it to rapidly release toxic munitions.

The Dual Toxocyst is a pair of Infestation b.svg Infested sidearms oriented towards DmgPunctureSmall64.png Puncture damage. Successfully achieving a headshot with this weapon temporarily grants it increased fire rate, additional DmgToxinSmall64.png Toxin damage, reduced recoil and infinite ammo. However, its initial recoil is very high and initial fire rate is very slow.

This weapon can be sold for Credits64.png 7,500.


This weapon deals primarily DmgPunctureSmall64.png Puncture damage.


  • High DmgPunctureSmall64.png Puncture damage – effective against armor.
  • Very high status chance.
  • Very good ammunition efficiency.
  • Landing a successful headshot grants the "Frenzy" buff, increasing fire rate by 150%, increases Ammo Efficiency by 100%, reduces recoil, and gains a bonus of 100% of its base damage as DmgToxinSmall64.png Toxin damage. The buff lasts 3 seconds and can be refreshed on subsequent headshots.
  • Innate Madurai Pol.svg and Naramon Pol.svg polarities.



The Dual Toxocyst's blueprint can be researched from the Bio Lab in the dojo.

  • Frenzy buff increases fire rate by 150%, doesn't consume ammo while firing, significantly reduces recoil, and gains a bonus of 100% of its base damage as DmgToxinSmall64.png Toxin damage. The buff lasts for 3 seconds and can be refreshed.
    • The buff triggers only on headshots, and not other weakspots, such as the backpacks of most MOA variants. Similarly, shooting weakspots generated by either Sonar130xDark.png Sonar or Mod TT 20px.png Detect Vulnerability in places other than heads will have no effect either.
      • Headshots on corpses will not grant the buff.
    • The fire rate bonus stacks multiplicatively after any equipped fire rate mods or fire rate bonuses. This can also be considered as applying to the base fire rate first before any additions.
    • The bonus DmgToxinSmall64.png Toxin damage can combine with other elemental mods equipped on the weapon, ex. having Mod TT 20px.png Heated Charge or Mod TT 20px.png Scorch equipped will make the Dual Toxocyst deal DmgGasSmall64.png Gas upon activating the buff.
    • If the Dual Toxocyst is modded with a combined element such as Corrosive, the bonus toxin damage will be added to that element's damage.
    • If the bonus is triggered or if it disappears, this weapon makes a noise that will alert nearby enemies. This noise cannot be reduced with Mod TT 20px.png Suppress or Mod TT 20px.png Hushed Invisibility.
    • Triggering the buff with the last bullet of the magazine does not require the user to reload the weapon before shooting again because it stops consuming ammo, and therefore is an effective candidate for Mod TT 20px.png Synth Charge.
    • The bonus DmgToxinSmall64.png Toxin damage is applied toward the "Toxin Mod Multiplier" for DmgToxinSmall64.png Toxin damage-over-time, as opposed to the base damage of the weapon where both initial damage and damage-over-time would simply double.
      View Status Proc Math List

A toxin mod multiplier determines DmgToxinSmall64.png Toxin proc damage per tick by Base Damage × (Toxin Mod Multiplier ÷ 2). For example, with Mod TT 20px.png Hornet Strike, Mod TT 20px.png Pathogen Rounds, Mod TT 20px.png Pistol Pestilence, Mod TT 20px.png Expel Grineer and the +100% "Frenzy" toxin bonus:

Base Damage = 75 × (1 + 2.2) × (1 + 0.3) = 312
Toxin Mod Multiplier = (1 + 0.9 + 0.6 + 1) × (1 + 0.3) = 4.55x
Toxin Damage per tick = 312 × (4.55 ÷ 2) = 709.8


  • The headshot buff can completely counter the weapon's low innate fire rate and max ammo capacity.
  • Use of the increased zoom module Mod TT 20px.png Hawk Eye can make gaining the headshot buff easier, thus significantly increasing the weapon's damage outputs and versatility.
  • While under the effects of the triggered buff, the fast fire rate and unlimited ammo, combined with the low critical chance and average critical multiplier make rapid fire bodyshots more viable than aimed headshots.
  • Mod TT 20px.png Hydraulic Crosshairs can be triggered at the same time as the buff, though the low base critical chance makes this mod of limited utility.
  • Installing Mod TT 20px.png Steady Hands completely negates recoil while buff is active.


  • The Dual Toxocyst is the first infested dual pistol added to the game.
  • Triggering the innate headshot buff or reloading the weapon will cause the Dual Toxocyst's barrel to open up like jaws, connected by infested tissue between its upper and lower parts.
