The Kestrel boomerang is a heavy throwing weapon that can knock down enemies at a distance.

The Kestrel is a melee throwing weapon similar to the DEGlaive Glaive, capable of bouncing off surfaces when thrown. Unlike the Glaive, the Kestrel can knock down any opponents that it hits at range.

This weapon deals primarily Impact b Impact damage. 


  • High Impact b Impact damage – effective against shields.
  • Slam Attacks have innate Magnetic b Magnetic damage – effective against Shielded and Proto Shields.
  • Possesses momentum during regular swings, which resists interruption such as stagger or knockdown.
  • Charge Attack throws the glaive, which can bounce up three times or travels up to 30 meters before returning to the user, damaging anyone in its path.
    • Thrown glaive has innate Blast b Blast damage – effective against Machinery and Robotics.
    • Thrown glaive has a guaranteed Impact b Impact proc.
    • Primary and secondary weapons can be fired and reloaded can be used normally with a thrown glaive, and retrieving the glaive does not interrupt these actions.
    • Thrown glaive is silent.
    • Glaive can explode mid-flight by pressing the melee button which forces a return or after hitting an object or enemy on the last bounce with Mod TT 20pxPower Throw equipped.
  • Can be wielded in-tandem with a single-handed secondary weapon.
  • Can use the Kestrel-exclusive Mod TT 20pxEntropy Flight mod.
  • Innate Madurai Pol and Naramon Pol polarities.


Weapon Loadouts


  • When equipping the Kestrel, the player can throw it and then press the channeling button to detonate the Kestrel, dealing high AoE damage and returns to the player immediately. This is true for all thrown melee weapons.
    • This is very useful for regenerating health with Mod TT 20pxLife Strike.
    • It can explode in this manner when not equipped and thrown, but the explosion timing cannot be controlled and will often damage the user in close quarters.
    • It should be however noted that finisher attacks can still be executed while the weapon is in the air.
  • The Ground Finisher's bleed proc damage is based on the Ground Finisher damage (which is 30 * 400% = 120 damage without mods). Therefore, the bleed damage can be increased with anything which affects the Ground Finisher, including Channeling and the Mod TT 20pxFinishing Touch mod.
    • For example, a Kestrel without any mods will deal 42 damage (= 120 * 35%) per bleed tick. With only a fully leveled Mod TT 20pxFinishing Touch, this is increased to 67 damage and to 100 damage while channeling.
    • Because bleed damage ignores shields, the Kestrel's Ground Finisher can be made into a potent attack against Corpus, especially when combined Toxin b Toxin elemental mods.
  • With Mod TT 20pxEntropy Flight unique to it and Mod TT 20pxWhirlwind, the Kestrel can attain a higher flight speed than any other thrown melee weapon with Whirlwind. This also indirectly increases its maximum range.


  • When used on a boss they can be permanently stunlocked if a Dethcube is firing at it, causing it to reset the recovery animation. This is fixed by shooting him directly. 
  • Can hit theoretically infinite targets on return.
  • Like with other thrown weapons, using Mod TT 20pxWhirlwind on the Kestrel will increase flight speed as well as distance traveled, because the flight time is constant. A fully leveled Mod TT 20pxWhirlwind will increase the maximum distance to ~63m.
  • When not in use, the Kestrel sheaths under your right arm.
  • Ragdolled enemies' health and shield bars are also concealed while ragdolled.  Although they usually display damage indicators while ragdolled, sometimes they will not display if you are not the host - giving the impression that the enemy is invulnerable (not the case).
  • Sometimes it will continuously fly around its user in a circular path indefinitely after bouncing off at least 2 objects, such as two adjacent walls, if the user stands back and stays still afterwards. (Possibly intended but its exact mechanics are unknown, however, Mod TT 20pxRebound and Mod TT 20pxWhirlwind were installed when this was discovered.)
    • Simply installing a max rank Entropy Flight mod will also cause this. The Kestrel is considered flying on a return path the entire time, so it punches through everything it hits. If the player moves too quickly, they will catch the Kestrel; however, if it is carefully maintained, it can continually fly around the player and deal large amounts of damage to everyone in the vicinity.
    • High flight speed, which causes this orbiting behavior, does carry some risk, as a current bug can cause the thrown weapon to disappear, disabling melee for the rest of the level or until the player has died & revived.


  • The Kestrel is a carnivorous bird in the falcon family known for hovering.
  • The Kestrel shares the same sheath style with the other thrown melee weapons, where they retract and attach under the right forearm.

  • Kestrel with Radiation damage

    • It ain't buffing the damage of the throw on the throwing weapons, i think it should just as Pressure Point does :Z
    • Wrong. Throw unranked Kestrel in Kurbow Den on Earth - it deals 30 damage without Steel Charge and 48 with it, so it's exactly 60% dam...
