Blood Bombs is a passive item added in The Binding of Isaac: Repentance.

Effects

• Gives Isaac a heart container and heals him for five hearts.
• Causes Isaac's Bombs to leave a pool of red creep on the ground when they explode.
  • The creep deals 2 damage per tick (20 per second) and lasts 15 seconds.
  • Leaves one large creep in the middle, and four small creeps on random direction and distance.
    • Multiple creeps do not inflict damage on an enemy simultaneously.
• If Isaac has no bombs, allows him to place a bomb at the cost of taking half a heart of damage. This prioritizes Red Hearts over Soul Hearts.

Notes

• Placing a bomb using health counts as self-damage, and as such, does not affect the chances for a Devil deal, does not trigger Damocles, nor does it reroll Tainted Eden.
  • The Lost / Tainted Lost will die if a bomb is placed this way.
    • This includes the version of The Lost you turn into after touching the white fireplace in II.
• Keeper / Tainted Keeper will take 1 Coin Heart of damage in exchange for 1 bomb.
• You can remain at zero bombs and leave excess drops of bombs and hearts to maximize resource use for the floor.
• Placing a bomb using health can let Isaac enter/exit a Curse Room without taking soul/black heart damage.
  • But be careful and remember to move quickly upon exiting the Curse room, otherwise you'll take damage from the previous bomb.

Interactions

• Bob's Rotten Head/ Dr. Fetus/ Epic Fetus/ Bomber Boy/ Scatter Bombs: Leaves a pool of red creep on the ground after each explosion.
• Creeps from following items can inflict damage on an enemy simultaneously:
  • Holy Water
  • IBS
  • Lemon Party
  • Lil Spewer
  • Mysterious Liquid
  • Toxic Shock
• Creeps from following items do not inflict damage on an enemy simultaneously:
  • Anemic
  • Aquarius (overrides the damage)
  • Bob's Bladder (overrides the damage)
  • Depression
  • Isaac's Heart
  • The Scooper
  • Shard of Glass
• Lost Cork: Does not increase the radius of creeps.

Trivia

• This is the only bomb-augmenting item that does not give any Bombs on pickup.
  • The fact that the item gives a heart container and healing instead of bombs may be a hint for the mechanic of using health for bombs, as well as a substitute for actual bombs.
  • The fact that the item heals 5 hearts may be a reference to many bomb effect items (such as Butt Bombs) that gives Isaac 5 bombs.
• The fact that the item gives a heart container and heals up to exactly 5 containers, along with the appearance, makes it very similar to Blood Bag.
• A Blood Donation Machine will be shown as a cause of death on Isaac's last will if he dies as a result of placing a bomb and losing all health.
