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 HarrowHarrowIcon272.png Harrow's signature speargun, firing fully automatic Corrosive DamageDmgCorrosiveSmall64.png Corrosive projectiles that explode and damage nearby enemies in a small radius. Its Alternate Fire allows the very weapon itself to be thrown, inflicting a Bullet Attractor field on the heads of all enemies near the impact point.


This weapon deals Corrosive DamageDmgCorrosiveSmall64.png Corrosive damage on its primary fire and primarily Impact DamageDmgImpactSmall64.png Impact damage on its alt-fire.



  • Innate Corrosive DamageDmgCorrosiveSmall64.png Corrosive damage – less effective against Proto Shields.
  • Extremely low critical chance and critical multiplier.
  • Low fire rate.
  • Low reload speed.
  • Projectiles have travel time.
  • All explosions inflicts self-stagger.
  • Primary fire explosion has linear damage falloff from 100% to 70% from central impact.
  • Alternate fire explosion has linear damage falloff from 100% to 40% from central impact.
  • Once thrown, the player will not be able to use it until it is either picked up or when it returns to the player after 20 seconds.


The Scourge's blueprint can be researched from the Tenno Lab in the dojo.

  • The Scourge's projectiles explode upon contact, and allows ​FirestormMod TT 20px.png Firestorm​ to be equipped to increase the blast radius, although it will only increase by ~1 meter.
  • The Scourge's alt-fire throws the speargun towards the reticle, impaling enemies along its path with physical damage, then inflicting Corrosive damage in a large area of effect. Finally, it creates a pulse that applies a Bullet Attractor debuff on nearby enemies' heads.
    • Bullets and projectiles fired at enemies will be drawn to the head. However, this does not guarantee a headshot.
    • The Bullet Attractor debuff will be applied the instant the weapon sticks to a surface, and subsequently in periodic pulses while the Scourge stays in place. There is a slight pause between their expiration and the next pulse; the Bullet Attractor effect lasts for 3 seconds and the weapon will pulse every 5 seconds, meaning there's a 2 second downtime. From testing, it appears that the Bullet Attractor affect cannot be increased with status duration mods.
    • After thrown, the weapon's location will be marked with a blue icon on the minimap.
    • The weapon will return to the Warframe after 20 seconds, or when picked up by moving over the planted weapon. Doing the latter will remove all Bullet Attractor effects from enemies and will immediately equip the weapon.
    • The Bullet Attractor effect will apply to all enemies within 13 to 14 m, there is no cap. There is no line of sight restriction.
    • Throwing Scourge at full ammo vs. 1 ammo left in the magazine does not have any notable difference (if any at all).
      • The Scourge can only be thrown if it has at least 1 ammo remaining in the magazine.
    • FirestormMod TT 20px.png Firestorm​ does not affect the size of the headshot bubble, nor does it increase the range a thrown Scourge will apply its effect to enemies.
    • Weapons with buffs that apply on headshots such as KnellPriestPistol.png Knell, Dual ToxocystInfVomitGun.png Dual Toxocyst and AthodaiAthodai.png Athodai will benefit greatly from the Scourge's alt-fire effects as they will easily gain their respective headshot buffs. Similarly, headshot-conditions for Arcane PistoleerArcanePistoleer64x.png Arcane Pistoleer and Arcane PrecisionArcanePrecision64x.png Arcane Precision can be easily achieved in this manner.
    • Throwing the weapon does not cost ammo.
  • An additional feature of the Scourge is its innate ability to replenish its magazine while holstered or thrown. In either state, the weapon fully reloads in 3 seconds (or 33% of the magazine size per second).
  • The Scourge has a unique visual effect with Harrow's Agile idle stance, where it will be collapsed into a smaller configuration when held. It extends to its full length when firing.
  • Manually reloading during the alt-fire charge will reload faster using the Throw's 0.6s instead of the primary 2.5s.
    • Quickly, while holding the alt-fire (default MMB ), tap reload (default R ).
    • Pressing or releasing the Sprint key (default Shift ) or the Crouch/Slide key (default Ctrl ) may delay the reload.


  • 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 BlastMod TT 20px.png 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.

Update 27.2 (2020-03-05)

Self Damage Changes

We are getting rid of Self Damage and replacing it with something else: instead of Self Damage, it’s now ‘Stagger’. This change completely removes the chance of killing yourself, and instead now creates scenarios where you will interrupt yourself - or ‘Stagger’ - to varying degrees if you aren’t careful.

The degrees of Self-Interrupt start with a small stumble all the way to full knockdown depending on how close you are to the center of explosion. Any Mods referring to Self Damage will be converted to acknowledge Stagger.

With this Self-Interrupt system, we have added dozens of new recovery animations that harness a ninja-like recovery experience. By pressing ‘Jump’ at the correct time, you can execute a ninja-skill-based knockdown recovery to ALL in-game knockdowns. This ninja recovery window is indicated by a glowing FX on your Warframe.

In the original Dev Workshop, we said:
As a result of this overall systemic change, Weapons with Stagger will be getting approximately a 20% buff in Damage, with any weapons with AOE receiving a 50% Radial Damage Falloff from central impact.

This is no longer accurate after continued testing. What we are doing now is:

No damage buffs have been added, but any weapons with AOE are receiving ~20% increase in Radius. Additionally, AOE weapons are receiving a 90% Radial Damage Falloff from central impact. This means on the very outer section of the explosion Radius 10% of the Damage will be dealt. Tactics will be deadly - aim true, Tenno.

Why: Several players brought up the history of the Tonkor and we want to make sure we ship this change in a place that’s conservative in its starting point from a balance perspective. The complete removal of Self Damage does change the pace of destruction with some of the game’s most powerful weapons, so we want to make sure we can iterate upwardly instead of releasing a bonanza of explosions with no other choices.
