Knockout Drops is a passive item.


  • Adds a chance to fire fist tears, which have massive knockback and briefly stun enemies.
    • Knocked back enemies will do contact damage to enemies they collide with.
    • Tears from Knockout Drops can even knock away stationary bosses such as It Lives or Mega Maw, although they'll snap back to their previous position.
    • The chance to fire a fist tear depends on the luck stat, reaching 100% with 10 luck.


  • If a fist tear hits an enemy with multiple body segments like Chub, all segments are knocked back and collide with each other, dealing extremely high damage. It is possible to kill these enemies with only one fist.


  • Brimstone/Technology: The laser knocks back enemies.
  • Perfection: Since the item requires 10 Luck to activate every time, picking up this trinket when Luck is 10 or more will make the effect constant.
