The Chaos Card is a special card.


  • Upon activation, Isaac throws the card in front of himself.
    • The card is thrown in the direction Isaac's body is facing, meaning the card will be thrown in the direction Isaac is moving. If he is stationary, it will be thrown in the last direction that Isaac moved.
  • The thrown card kills anything in its path (including end-game bosses like ??? ??? and otherwise indestructible entities like Stone Grimace Stone Grimaces and Retractable Spikes) and gets stuck in the ground/wall after being thrown.
  • The card can open doors as if a Bomb Bomb had exploded them, although it can not open any locked doors or open the big door in the starting room of Dark Room Dark Room and Chest Chest.
  • The card can extinguish fires, break rocks, and open secret rooms.


  • Using it on multi-phase bosses like Isaac Isaac, ??? ??? and The Lamb The Lamb will instantly end the boss fight.
    • Using it on Satan Satan during his first form will end the fight, despite him having multiple forms and health bars. Using it on The Fallen The Fallen instead of Satan himself will not end the fight.
      • However, using it on Mega Satan Mega Satan will only skip one phase.
    • Removed in Repentance It will only kill one phase of Added in Afterbirth Hush Hush unless Isaac throws it from the bottom side, such that after killing the first phase, the card can still catch up with Hush's true form as he pops out at the top of the room. However, this method can fail depending on the timing and the position of the first phase.
      • Added in Repentance Only one phase of Hush can be skipped.
    • Added in Afterbirth † It will only kill one phase of Ultra Greed Ultra Greed in Greedier mode.
    • Added in Repentance It will only kill one phase of Mother Mother and Dogma Dogma.
  • To aim the card correctly, make sure to move in the direction that it needs to be thrown; shooting in a direction will not fire it in that direction.
  • Does not kill Beggar.png Beggars or Shopkeeper Shopkeepers.
  • Can kill normally indestructible enemies like the Masks of Mask + Heart Mask + Hearts (though this will not kill the heart), Host Hosts while they're invulnerable, the little chubs in Chubber Chubbers, and Death's Head Death's Heads. It can also be used to kill things typically not considered alive like Wall Hugger Wall Huggers and Stone Grimace Stone Grimaces.
  • If used on Pin Pin or Added in Afterbirth The Frail The Frail segments can be cut off causing both bosses to lose length like Larry Jr. Larry Jr..
  • Using it on an Angel Statue will reveal an Angel and kill them instantly.
  • Added in Repentance Great Gideon Great Gideon has a special death animation if killed using it, which also reveals a Crawl Space Crawl Space under him containing several Chests and items.
  • Added in Repentance Mother's Shadow Mother's Shadow cannot be killed with Chaos Card, though it is normally impossible to get one in the abandoned area of Mines Mines/ Ashpit Ashpit II.


  • Added in Afterbirth †Angelic Prism Angelic Prism: If the Chaos Card passes through the prism, it will replicate the Chaos Card four times each in their respective colors.
  • Blank Card Blank Card: Allows for an easy run by allowing unlimited usage of the card.
    • Items such as Habit Habit, 9 Volt 9 Volt, and Added in AfterbirthCharged Baby Charged Baby give more opportunities to use the card since all these items decrease the charge time of Blank Card.
    • The Battery The Battery allows Blank Card to be used twice in a room, allowing multi-phase bosses to be killed instantly.


  • The icon, name and functionality are all a reference to the Magic: The Gathering card Chaos Orb. This card is famous for its unusual effect: the card is flipped from a height of over one foot above the board and all cards it touches as it lands are destroyed.


Bug Bug! If used against Scolex Scolex while he's jumping, Chaos Card will not instantly kill him and will instead cut off the bottom of his tail, dealing some damage. Although his weak point will no longer be visible, its hitbox will be and can still be damaged as normal.
