Binding of Isaac: Rebirth Wiki

Added in Afterbirth

Milk! is an unlockable passive item added in The Binding of Isaac: Afterbirth.


  • Spawns a glass familiar that follows Isaac and spills on the floor upon taking damage.
  • When the milk spills, Isaac receives -2 tear delay (Added in Repentance +1.0 fire rate) (increased rate of fire) until leaving the room.
    • Direct tear delay reduction can take Isaac's tears stat below the normal soft cap of 5.
  • The milk puddle is purely visual, and will stay on the ground for a few seconds before disappearing. The familiar will reappear in the next room.


  • Removed in Repentance Box of Friends Box of Friends: The milk familiar is not duplicated; instead, tear delay decreases by 2 upon use even if the player has not taken damage in the current room.
    • Added in Repentance No extra tear delay is granted, neither before or after breaking.
  • Added in RepentanceRock Bottom Rock Bottom: If activated at least once, the increased rate of fire will always be active.


  • BFFS! BFFS!: Familiar is bigger but no effect on tear delay.
