This weapon primarily deals Corrosive b Corrosive damage.


  • Corrosive damage is effective against Ferrite armor and Fossilized health.
  • Projectiles explode upon contact.
    • Does not deal self damage to the user.
  • Projectile explosion damage is able to bypass Arctic Eximus and Nullifier Crewman bubbles, damaging enemies keeping refuge within.
  • The weapon does not need to charge up before firing, unlike the Javlok and Ferrox.
  • Secondary fire throws the Scourge to deal damage and cause Bullet Attractor-like fields on the heads of enemies near the impact point, allowing easier headshots with secondary weapons.
  • High ammunition capacity.
  • Very ammo efficient – uses rifle ammunition.
  • High status chance.


  • Projectiles have travel time.
  • Once the Scourge is thrown, the player will not be able to use it until it is either picked up or when it returns to the player's hands.
  • Very low critical chance.
  • Secondary fire deals self damage to the user, and may also self-proc any modded status effects.


  • The Scourge's projectiles explode upon contact, and allows Firestorm to be equipped to increase the blast radius, although it will only increase by ~1 meter.
  • The Scourge's alt-fire is a hurling move that sends the weapon towards enemies, impaling enemies along its path with physical damage and inflicting a large AoE that inflicts Corrosive damage on enemies as well as causing small Bullet Attractor-like fields to appear on their heads.
    • Bullets fired at enemies will be drawn to the head. This does not guarantee a headshot. Additionally, hitscan weapons are unaffected by this field.
      • Strangely, this means the Knell can benefit from the field, but only when the wielder is not aiming.
    • Bullet Attractor-like debuffs will be applied in pulses, while The Scourge stays in place, there is a bit of a pause between their expiration and the next pulse.
    • Naturally, Knell and Dual Toxocyst will benefit greatly from the Scourge's alt-fire effects as they will easily gain their respective headshot buffs.
    • Firestorm does not affect the size of the headshot-field.

Tips Edit

  • Using dual-stat elemental and status chance mods, such as Malignant Force and Thermite Rounds, can make Scourge achieve 100% status chance.
    • With its innate Corrosive damage that is effective against heavily armored targets like the Grineer, it is possible to add two more elemental damage types to maximize its status-based damage potential (such as adding Gas b Gas damage against the Infestation — and to some extent, against other enemies because of its Toxin b Toxin gas procs — and Magnetic b Magnetic damage against Corpus robotics to make Scourge a versatile weapon against most enemy types).
      • The above Corrosive-Gas-Magnetic build on the Scourge is found to be surprisingly effective at dealing with Nullifier Crewmen, as the procs can bypass through the nullifier bubble and deal direct damage on the crewmen themselves (this was tested on a lvl100 Nullifier Crewman in the Simulacrum).
  • Primary fire bypasses Frost´s Globes from both sides.
  • Tactical Reload works on this weapon while it is in a thrown state.


  • A Scourge refers to a whip with multiple thongs or "tails" (a Cat o' nine tails being a good example), and was often used for corporal punishment as well as for self-flagellation by religious penitents. In contemporary terminology, the term has been applied to people, groups, or events that resulted in great calamity.


  • Adhesive Blast could be used to allow the projectiles to stick then explode, but this feature was disabled, making the mod do nothing when equipped.
