See the user build section for builds using this weapon.
Can be used to instant-kill most bosses by flinging them into a pit while ragdolled. Loot can be found where they last stood. (Possibly a bug)
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.
When not in use, the Kestrel shealths 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 it's user in a circular path indefinitely after bouncing off at least 2 objects such as two adjacent walls if the user stand back and stay still afterwards. (Possibly intended but it's exact mechanics is unknown yet however Rebound and Whirlwind were installed when this was discovered.)
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 arm.
