This Sentient war instrument can either barrage targets with explosive bolts, or, draw on its regenerative battery to create twin plasma beams that chain through targets. When fully drained, Health is leached from nearby foes for a short period.

The Basmu is a Sentient rifle that fires rounds dealing Electricity DamageDmgElectricitySmall64.png Electricity damage on impact and explodes in a 1.7 meter radius for Heat DamageDmgHeatSmall64.png Heat damage. The Alternate Fire channels two beams of Electricity DamageDmgElectricitySmall64.png Electricity that conducts between targets, with its extreme critical multiplier offset by its low critical chance. When the battery is drained, the weapon releases a 10 meter pulse that staggers enemies and siphons health from them.


This weapon deals primarily Electricity DamageDmgElectricitySmall64.png Electricity damage.


  • Primary fire shoots rounds that explode in a 1.7 meter radius after impacting a surface or enemy.
  • Alternate Fire shoots two continuous beams that can chain up to 5 nearby enemies within 7 meters from the initial target, with each chain doing 50% of the previous chain's damage.
  • High fire rate.
  • Fully depleting the magazine produces three 10-meter pulses that deals up to 10 True DamageDmgTrueSmall64.png True damage, staggers nearby enemies and heals the user's health by 10x the damage done to each enemy per pulse.
  • Does not use ammo pickups; ammo regenerates over time.
    • Has a 2 second delay from empty before ammo begins to regenerate; if there are still rounds left, the delay is 0.2 seconds instead. Then, regenerates 42 ammo per second; takes 0.5 seconds to regenerate a fully depleted battery excluding the delay.
  • Innate Madurai Pol.svg polarity.

  • Pulse damage is affected by base damage mods (e.g. Serration12?cb=20190608095452 Serration, Heavy Caliber12?cb=20190608095452 Heavy Caliber).
  • Upon fully depleting the weapon's magazine, one healing pulse is released immediately, then releases additional pulses every 0.4(?) seconds.
    • The time between pulses is not affected by reload speed, meaning decreasing reload speed (and thus increasing reload time) results in more pulses, while increasing reload speed results in less pulses.
  • When fired at an enemy, the alternate fire will chain to the closest living enemy within 7 meters of the initial target. From there it will chain again, up to a maximum of 5 chains in total. A chain will do 0.5n times the main beam's damage, where n is the chain number.
    • The damages are : 100% for the main target, 50% for the first in the chain, 25% for the 2nd, 12.5% for the 3rd, 6.25% for the 4th, and 3.125% for the 5th.
    • Headshotting the original target does not affect the chain damage.
    • The beam will not chain to a Nullifier through its shield should it connect with a target outside or partially enclosed by it.
    • The beam can also continue to chain to enemies even if targeting a dead enemy.



  • The Bašmu is an ancient Mesopotamian mythological creature, a horned snake with two forelegs and wings.
  • Shortly after this weapon's introduction, a bug caused the healing pulses to take into account mods multiple times per pulse, exponentially increasing damage and killing any enemy within range. This glitch has since been fixed in Hotfix 27.3.16 (2020-04-22).


  • Primary fire is treated as silent.
  • The weapon will not emit healing pulses if the user is not touching a surface.
  • Using roll with Amalgam Barrel Diffusion will retrigger the pulse from reloading the basmu, allowing it to continuously pulse when the roll is timed with the 1st or 2nd pulse.
