This weapon deals exclusively VoidTearIcon b Void damage.


  • Innate VoidTearIcon b Void damage – effective against Sentient-type enemies.
  • Shots releases 3 grenades in a burst, with a splash range of 3.5 meters per grenade.
    • High total damage; direct impact damage of 1,000 VoidTearIcon b Void, and radial damage of 1,400 VoidTearIcon b Void.
  • High critical chance.
  • Relatively long range if aimed in an upward arc (up to ~75 meters).
  • Decent energy economy.
  • Slow energy consumption, consumes 10.35 energy/second at base fire rate.
  • Can immediately re-enter Void Mode after the last shot of the burst is fired.
  • Does not use ammo pickups; energy regenerates over time.
    • Has a 2-second delay after the weapon stops firing before regenerating energy.
      • Regenerates 30 energy per second; takes 3.33 seconds to regenerate a fully depleted energy meter.



  • This Operator Amp component allows the Void Beam to be fired in burst mode, releasing three void grenades that detonate on impact.
  • Each grenade deals damage in a 5-meter area of effect, allowing well aimed strikes to quickly strip away shields by dealing splash damage to multiple Teralyst limbs. Aiming at the lower half of the Teralyst can also clear out any Vomvalysts in the area.
  • Can deal self damage, albeit extremely low (1-2 health per grenade).
  • The listed energy cost is per projectile in a burst, meaning that the Granmu consumes 15 energy in a three-shot burst. The Granmu can still fire with a minimum of 5 energy, though it will only shoot 1 projectile, and having 10 energy will make it shoot two projectiles.
