Seeryul Killer is a legendary assault rifle in Borderlands 3 manufactured by COV. It is obtained randomly from any enemy that appears in Guns, Love, and Tentacles.

Look at that unsubtle blood-red coloring... – Killing an enemy reduces heat shot cost and increases damage and fire rate. The buff lasts for a few seconds and can be extended with further kills.

Usage & Description

The Seeryul Killer is a powerful incendiary assault rifle that benefits from killing enemies. With high stacks, it can dish out incredible amounts of damage at minimal heat gain, though this comes at the cost of the innate high ammo consumption of COV weaponry. The weapon should be treated like a kill skill, used to eliminate the weakest targets before using its buffs to kill more dangerous foes.


  • The weapon's projectiles need to cause the kill directly, damage over time effects do not seem to count even if caused by the weapon.
  • The buff causes a visual change to indicate the buff level.
    • The first kill causes blood to drip from the barrel, and buffs the weapon by x%.
    • The second kill adds an extra sparkle effect on the barrel, and buffs the weapon by x%.
    • The third kill adds a translucent red outline to the entire weapon, and buffs the weapon by x%.


  • The name is a homophone of "serial killer".
  • The flavor text is a reference to the 2000 film American Psycho. The original phrase is "Look at that subtle off-white coloring" in Patrick Bateman's thoughts while comparing business cards with his colleagues.
