When its twin-lasers converge on a target a circuit is created, frying the subject.

The Convectrix is a Corpus shotgun that uses two converging beams to slice enemies between them. It is researched from the Energy Lab in the Dojo.

This weapon deals primarily Slash b Slash damage.



  • Lowest damage of all shotguns.
  • Damage ramps up from 60% (primary fire)/80% (alt-fire) to 100% over 0.6 seconds when firing. After firing stops for 0.8 seconds, the damage decays back to 60%/80% over 2 seconds.
  • Before 100% status chance, the listed status chance is the base chance per shot that at least one beam will proc a status; the actual base status chance per beam is ~16.33%.
  • Limited range of 30 meters.
  • Does not deal full damage at the crosshair until both beams are aligned.
  • Alternate fire uses slightly more ammo than the primary fire.


  • The Convectrix fires two beams with a length of 25 meters from its twin emitters, which move into position when the fire button is held. If using primary fire, the beams are emitted at the sides and then converge into the center of aim; if using secondary fire, the beams begin from the center and then diverge outwards and back again in a sweeping motion.
    • The beams will deal damage to any enemies and objects caught within their length.
    • Maximum beam divergence spread is affected by Mod TT 20pxTainted Shell and Mod TT 20pxVicious Spread, respectively narrowing and widening the beam's initial spread.
  • The weapon's listed damage is split between the two beams, thus each beam deals half of the listed damage, per second.
    • This combined with the fact that the weapon must continually contact enemies for maximum damage, means the alt fire mode consumes more ammo, and often does less damage overall.
  • The most similar weapon to the Convectrix is the InfestedLongGunTwo Phage, an Infested continuous shotgun weapon that fires seven beams that move toward the center of the reticle when using the zoom function.
  • Other similar Corpus beam weapons include:
    • CrpShockRifle Quanta and QuantaVandal Quanta Vandal, rifles that also fire twin continuous beams.
    • CorpusLaserRifle Flux Rifle, a rifle that fires a single, continuous, slash-focused beam.
    • Spectra Spectra, a secondary that fires a single, continuous, slash-focused beam.


  • The Convectrix can use the Mod TT 20pxCombustion Beam mod to deal damage to enemies in range upon death.
  • Mod TT 20pxSinister Reach can be used to increase the Convectrix's range.
  • Consider using Mod TT 20pxShotgun Ammo Mutation to help regain ammo, especially in long duration mission types.
  • Mod TT 20pxVicious Spread has no effect at all on the beams when they are combined. While it slightly increases the radius of its sweeping pattern, the weapon converges the beams fast enough that it's not noticeable.
  • The Convectrix has a high chance of cutting corpses into pieces, making it an ideal candidate for a Desecrating NekrosIcon272 Nekros to bring along, as the game considers the cut corpses as separate entities, essentially giving multiple corpses to desecrate from a single enemy and thus yielding more chances to create more drops.
  • As fire rate will not increase the speed at which the two beams converge but the ammo drain, it is ill-advised to use too many fire rate mods if you can't utilize the beams while they are not converged.


  • Convectrix is likely derived from the word convex. A convex lens refracts multiple beams of parallel light to single focal point. This is similar to how the Convectrix works when the fire button is held, having two beams of energy converging to a single point.
  • May also refer to the words convene (v. to come together) or converge (v. to tend to meet in a point or line; incline toward each other, as lines that are not parallel.) which share similar origin and meaning.
  • When the beams are converged on an enemy, a singeing or burning sound can be heard, unique to the Convectrix.


  • Convectrix in Codex.


  • Using the secondary fire mode will flash "540" as your reserve ammo count, regardless of how much reserve ammo you actually have. This bug is only visual and the ammo count returns to normal upon release.
  • Rapidly firing the weapon and letting the beams converge over a short period will "stack" the sound affects, and after firing you will still hear "ghost" sound effects in that spot for as the game continues to cue these affects.

Patch HistoryEdit

Update 22.14
  • Fixed Beam weapons not being able to damage enemies (alive but in a ragdolled state) when being affected by certain ‘crowd control’ Abilities.
  • Damage now ramps up over 0.6 seconds and after moving off target there is a delay of 0.8 seconds before it starts to decay over 2 seconds.
  • All Beam weapons now start their Damage ramp up at 20% (instead of 10%) with the following exceptions:
    • Convectrix
      • Primary fire starts at 60%.
      • Alt fire starts at 80%.
  • The Multishot chance should now apply more consistently with Beam weapons.
  • Fixed Beam weapons continuously firing when quick Meleeing.

Hotfix 22.13.4

  • Increased the Beam weapon Damage ramp up time from 0.8 to 1 second.
  • Fixed Beam weapon Damage ramp up not happening per target.
  • Convectrix Alt Fire beams now continuously sweep back and forth.
  • Fixed the Convectrix showing different Ammo types between fire modes. (Alt-fire is now using Shotgun shells like Primary fire)
  • Fixed Convectrix beams visually crossing each other.

Hotfix 22.13.3

  • Perfect accuracy and high fire rate is balanced by limited range and damage ramping up from 10% to 100% over 0.8 seconds when firing and decays back to 10% over 1 second after stopping.
