Blast targets with corrosive plasma projectiles, or toss the scepter to inflict nearby enemies with an energy field that amplifies their brain waves to attract bullets.

The Scourge is Harrow's signature Speargun, firing fully automatic Corrosive b Corrosive projectiles that explode and damage nearby enemies in a small radius. The Scourge can be thrown as Alternate Fire, inflicting a Bullet Attractor field on the heads of all enemies near the impact point.

This weapon deals Corrosive b Corrosive damage on its primary fire and primarily high Impact b Impact damage on its alt-fire.


  • Innate Corrosive b Corrosive damage – effective against Ferrite Armor and Fossilized.
    • Innate Corrosive b Corrosive damage can rapidly strip away armor.
    • Lack of physical damage; guaranteed to proc elemental damage types.
  • High Impact b Impact damage and good Slash b Slash damage on alt-fire – effective against shields and flesh.
  • Primary fire impacts on enemies or surfaces causes an explosion that damages all enemies in a small radius.
    • Does not deal self damage to the user.
  • Alt-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.
    • Explosion bypasses Arctic Eximus globes and damages enemies within.
    • Explosion pushes enemies away from point of impact.
  • Very high status chance.
  • High ammunition capacity.
  • Very ammo efficient.


  • Innate Corrosive b Corrosive damage – less effective against Proto Shields.
  • Extremely low critical chance on both primary fire and thrown spear.
  • Projectiles have travel time.
  • Low fire rate.
  • Low reload speed.
  • 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 after 20 seconds.
  • 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 area of effect 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.
    • 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).
    • Inherent Corrosive damage allows for optimal anti-Grineer builds, utilising all three of Corrosive, Viral, & Radiation damage types.
      • Viral damage gains a 75% damage bonus vs Cloned Flesh, possessed by all Grineer organic units.
      • Either Corrosive or Radiation damage gain a 75% damage bonus vs armor, ensuring that one of these stats will always deal bonus damage.
  • 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.
  • Has a high chance of disappearing when thrown.


  • Scourge in the Codex.
