IV Bag is an activated item.

Effects[edit | edit source]

  • When activated, causes Isaac to lose half a heart (or a full heart in The Womb and beyond) while spawning 1-3 coins.

Notes[edit | edit source]

  • This effect is counted as inflicted damage for the purpose of items that spawn pickups upon damage, such as Gimpy or Fanny Pack, but does not count against the chance of encountering the Devil Room.
  • Invulnerability will not prevent Isaac from losing hearts.
  • Spawns 0-1 coins when playing as Keeper.
  • If down to half a heart (or a full heart in The Womb and beyond), it will take soul or black hearts instead of red hearts.
  • When playing as the Lost, using the item will be an instant kill through Holy Mantle.
  • Since using the IV Bag still causes invulnerability, using it just before getting hit, walking over spikes, or going through a Sacrifice Room will grant coins without inflicting extra damage.

Synergies[edit | edit source]

  • Portable Slot Portable SlotPortable Slot Icon.pngUnlimitedUpon activation, 1 coin will be consumed, and a random pickup may drop, similar to the slot machine.: Can be alternated between to gain ridiculous amounts of pickups from only a few initial coins or hearts.

  • Scapular ScapularScapular Icon.pngOnce per room, when Isaac is reduced to his last half red Heart, the aura around his head temporarily vanishes and he is granted one Soul Heart.: Allows for infinite coins once Isaac is at half a red heart (or full red heart in The Womb or beyond) by moving between rooms to reset Scapular's effect.
  • The Wafer The WaferThe Wafer Icon.pngAll sources of damage that would cause more than one half heart of damage are reduced to one half heart instead.: Even in The Womb and beyond, IV Bag only takes half a heart.

Trivia[edit | edit source]

  • A glitch in the original Binding of Isaac existed where the player could leave a room and activate the item during the invincibility frames offered during recovery of using the items, effectively spawning infinite coins. This bug has been fixed in The Binding of Isaac: Rebirth.
