Binding of Isaac: Rebirth Wiki

Holy Water is a passive item.


  • Removed in Repentance Spawns a familiar that follows Isaac. If Isaac takes damage, it will shatter and create a pool of damaging blue creep, similar to Lemon Mishap Lemon Mishap.
    • The pool lasts for ~9 seconds and deals 8 damage per tick to non-flying enemies (24 damage per second).
    • After breaking, Holy Water will reappear in the next room.
  • Added in Repentance Spawns a familiar that follows Isaac and launches itself in the direction Isaac shoots. Upon hitting an enemy, it will deal 7 damage and shatter, creating a pool of damaging blue creep that also petrifies enemies that touch it.
    • Once the pool disappears completely, Holy Water will respawn and can be fired again. Holy Water does not immediately respawn upon entering a new room.


  • BFFS! BFFS!: Familiar is bigger but no effect on damage.
    • Added in Repentance Doubles the initial damage and causes it to also spawn a blue flame on point of impact that blocks shots and deals 6 contact damage per tick to enemies (36 damage per second). The fire can hit flying enemies, persists for the same amount of time as the creep, and cannot be destroyed.
  • Vasculitis: Upon killing an enemy while they are inside the puddle of holy water, The enemy bursts into a cluster of petrifying tears.
