Keeper sprite

Purity is a passive unlockable item exclusive to Afterbirth DLC for The Binding of Isaac: Rebirth.


  • Purity will boost Isaac's stats depending on the color of the aura around him:
    • Red: +4 Damage
    • Orange: +7.5 Range, +1.0 Tear Height
    • Yellow: +0.5 Speed
    • Blue: -4 Tear Delay


  • If Isaac gets hit, the aura will vanish. The aura will reappear in a random color when the next room is entered.
  • The additional tear delay can allow the player's tears to go over the normal maximum tear rate.
