(in Repentance)

Knockout Drops is a passive item added in The Binding of Isaac: Repentance.

Effects[ | ]

  • Adds a chance to shoot red fist-shaped tears that deal extreme knockback and cause confusion for 2 seconds.
    • Enemies will take 10 + 2 * (floor - 1) damage when they are knocked into a wall/obstacle or when hit by another knocked back enemy.

Notes[ | ]

  • The chance to fire fist tears depends on the luck stat, and the formula used to determine the chance is:
    • At base luck (0), the chance is 10%, maxing out at 100% at 8.01 luck.
  • Bosses are also affected by all of Knockout Drops' effects.
  • Fist tears play a unique punch sound effect when they hit enemies.
  • Knockout Drops can be dangerous in Boss The Beast ingameThe Beast battle, as the Ultra Harbingers may get knocked so far off the screen they become hard to damage further and their attacks cannot be seen properly.
