Void is an unlockable activated item added in The Binding of Isaac: Afterbirth †.


  • Upon use, destroys all pedestal items in the room. Items that require payment can not be absorbed unless they are bought first.
    • If Void destroys an active item, it gains the activated ability of that item - whenever Void is used, it will simultaneously use all previous active items that were absorbed in the same order they were absorbed. Passive effects of absorbed active items will not apply (i.e. the passive effect of Mom's Box Mom's Box).
    • If Void destroys a passive item, Isaac gains 2 random stat boosts. Possible stat changes include:
      • +1 flat Damage
      • Removed in Repentance +0.5 Tears
      • Added in Repentance +0.5 Fire Rate, which can exceed the normal maximum tears limit.
      • +0.2 Speed
        • Removed in Repentance Also affects maximum speed (may never exceed 2.0)
      • +0.2 Shot Speed
      • +1 Luck
      • +0.5 Range (Added in Repentance+1.5 Range)
      • If speed or tears are at their maximum and are chosen, there will be no visible increase.
        • Added in Repentance This still applies to the tears stat, however it is more difficult to see as the hard tear cap has been increased to 120.


  • Apollyon Apollyon starts with this item by default.
  • Using Void to absorb items in Boss Rush Boss Rush or Challenge Room Challenge Rooms counts as taking the items and will cause waves of bosses or enemies to start spawning.
  • Removed in Repentance The ability of the newly absorbed active item(s) will activate even if the item has no charge. Using any multiple-use item before absorbing it with Void will effectively allow Isaac to use the item twice.
  • Added in Repentance If Void is used while Isaac is holding an item above his head, it can still consume the item, allowing to immediately absorb passive items bought from Devil Room Devil Rooms, Black Market Black Markets, or Shop Shops. This also can be used to give Isaac a chance to see what an unknown item is before deciding if he wants to consume it, in the case of an active Curse of the Blind.png Curse of the Blind or a Treasure Room Treasure Room in Downpour Downpour, etc.
    • This does not apply if Void had previously absorbed an active item that normally hold itself above Isaac's head, i.e. Bob's Rotten Head Bob's Rotten Head.
    • This mechanic can be used to absorb familiars granted by Added in RepentanceSoul of Lilith Soul of Lilith.
  • Added in Repentance The newly absorbed active item(s) won't be used right away, but with the next usage of Void.
  • Added in Repentance If Isaac absorbs items from a room with choice pedestals, it will only absorb one item, and the other item vanishes as if Isaac took it.
  • If Isaac finds another Void, such as during a Victory Lap where it is left behind in the previous lap, it will have the same active effects stored in it as the other Void.
    • Consuming a second Void will create no effect.
  • If multiple copies of an active item are absorbed, using Void will activate that effect equally many times.
  • Stat boosts upon destroying passive items are determined by the seed and are tied to the number of items destroyed, not the items themselves. If Isaac runs the same seed and chooses to consume different passive items, the same stat boosts will be gained.
    • Added in RepentanceVoid's RNG is advanced once after each usage, so using Void will change what stat boosts you gain.
  • Stat boosts are permanent and are retained if Void is dropped.
  • Using Void to absorb Key Piece 1 Key Piece 1 and Key Piece 2 Key Piece 2 will not permanently remove them from the run. They will continue to spawn after defeating Uriel Uriel or Gabriel Gabriel no matter how many times Isaac uses Void on them, as long as he does not pick them up normally.


  • Added in RepentanceAlabaster Box Alabaster Box: Allows the box to be charged through normal means, rather than by absorbing soul hearts.
  • Added in RepentanceBook of Virtues Book of Virtues: Spawns the wisps of all the active items Void has absorbed. Spawns no wisps by itself. Using Void on Book of Virtues will give stat upgrades instead of its normal effect, as Book of Virtues is considered a passive item.
  • Breath of Life Breath of Life: Immediately grants invincibility frames.
    • Added in RepentancePanic Button Panic Button: Getting hit with Breath of Life stored inside Void will negate the damage.
  • Removed in RepentanceCrooked Penny Crooked Penny: Using Void with the Crooked Penny absorbed will result in items in the room being absorbed as usual, but afterwards new copies of the items or one coin are spawned.
    • Added in Repentance If Crooked Penny deletes the contents of the room, they will not be consumed by Void.
  • Added in RepentanceEraser Eraser: Allows the Eraser to be used multiple times per floor.
  • Glass Cannon Glass Cannon: can be used without it ever breaking or causing damage to the player.
  • Removed in RepentanceMore Options More Options / Removed in RepentanceThere's Options There's Options: Using Void will cause both items to be absorbed.


  • Added in RepentanceAbyss Abyss: Since consumed activated items are used before absorbing new items in a room, using Void with Abyss stored inside will make all pedestal items be destroyed by Abyss first, essentially overriding Void's item consumption effects. Previously-consumed activated items will still function as normal when using Void.
  • Blank Card Blank Card + ? Card ? Card: Using the ? Card with an absorbed Blank Card simply activates Void. Isaac will not be teleported to the I AM ERROR I AM ERROR room and Void will not be deleted.
  • Broken Remote Broken Remote / Teleport! Teleport! / Teleport 2.0 Teleport 2.0 / Undefined Undefined / any other teleport method: Void will still consume any item pedestals in the room, after which the teleport occurs.
  • Added in Repentance Clear Rune Clear Rune + Soul of Lilith Soul of Lilith: The familiar that the latter generates will immediately be consumed by Void.
  • Removed in RepentanceClicker Clicker: If Void is either Isaac's only item or the item most recently picked up, it will be lost upon absorbing due to Clicker activating.
    • Added in RepentanceIf on the next usage of Void no new items have been found, Void will be deleted.
  • The D6 The D6 / D100 D100: If absorbed while there are other pedestal items in the room, it will reroll the items before absorbing them. Likewise, if The D6 or D100 was previously absorbed and Void is used, pedestal items will get rerolled before being absorbed.
  • Removed in RepentanceD Infinity D Infinity: When absorbed and Void is used, replicates the effect of a random die item.
    • Added in Repentance Acts as a copy of one of the 10 dice D Infinity D Infinity can replicate. This die is randomly chosen and does not change.
  • Removed in Repentance Diplopia Diplopia / Forget Me Now Forget Me Now / Pandora's Box Pandora's Box / Mama Mega! Mama Mega! / Mystery Gift Mystery Gift / any single-use active item: They are used once upon being absorbed, but their effects are not absorbed and will not activate with subsequent Void uses.
    • Added in Repentance Single-use items won't be used upon their absorption, instead being invoked on the next usage of the Void, which allows Isaac to use the absorbed item later when needed. Their effects will still only be invoked once.
      • Car Battery Car Battery As Void will be activated twice, single-use items are immediately used when absorbed.
    • Added in RepentanceDiplopia Diplopia: On the next use, the pedestal items in the room will be consumed but another copy of the items will be spawned afterward.
      • Diplopia Diplopia + Mystery Gift Mystery Gift: If both items are absorbed in the same room, the next use of Void will only trigger Diplopia, with the use afterward activating Mystery Gift
  • Added in RepentanceEverything Jar Everything Jar: Consuming Everything Jar will cause Void to spawn a poop when used, regardless of charge level.
  • Added in RepentanceFlip Flip: When consumed by Void, it doesn't create ghost pedestals.
  • Removed in Repentance Glowing Hour Glass Glowing Hour Glass: Upon using Void, Isaac is sent to the previous room and most changes are reverted, nullifying many other effects that Void may have absorbed. If the Glass is absorbed in a shop, Isaac is sent back to the previous room, but the Glass will be unused in the shop on its pedestal. This allows for an infinite shop donation circle, eliminating the need for a battery to be present in the shop.
    • Added in Repentance Charges are reset back to full upon each use, allowing for infinite re-tries of any room. This does, however, prevent any other items consumed previously from being invoked, and usually prevents Isaac from absorbing new items.
  • The Jar The Jar: Absorbing it with Void will not allow Isaac to pick up excess hearts.
  • Jar of Flies Jar of Flies: Absorbing it with the Void will not allow the collection and generation of flies.
  • Added in RepentanceJar of Wisps Jar of Wisps: Each use will spawn only one wisp.
  • Moving Box Moving Box: Moving Box will not be added to Void; instead, it is converted into stat boosts like a passive item.
  • Remote Detonator Remote Detonator: Absorbing it with Void does not cause bombs to remain on the ground until Void is used, but using Void explodes all player-placed bombs as usual.
  • Telekinesis Telekinesis: Telekinesis effect will trigger anytime the Void will be used.
  • Added in RepentanceSharp Key Sharp Key: Using the Void will cause Isaac to shoot a key the next time he will press the fire key. Keys are consumed as always.
  • Added in RepentanceSpin to Win Spin to Win: A spinning top orbital will spawn every time the Void is used. The orbitals will last until Isaac leaves the room.
  • Added in RepentanceStitches Stitches: Absorbing it with the Void won't do anything since the familiar doesn't spawn.

In-game Footage[]



  • When this item was originally teased, it had a recharge counter of four and converted pickups into blue flies; in its release, it was nerfed to a recharge counter of six and the ability to convert pickups to flies became the item Compost Compost.
    • The original effect of the item may have become a base for Void's future counterpart, Added in RepentanceAbyss Abyss.
  • Before the balance patch on 5 January 2017, Void synergized with single-use items such that it would trigger them upon each use of Void; this has since been removed.
  • Void is one of only five items to appear in both the Angel Room and Devil Room item pools, the others being 7 Seals 7 Seals, Lil Delirium Lil Delirium, Duality Duality and Added in RepentancePurgatory Purgatory.
  • Added in Repentance Void is the only Afterbirth † item with a quality of 4, besides Mom's Shovel Mom's Shovel and the Broken Shovel pieces.
  • The swirl in Added in RepentanceAbyss Abyss's appearance is in the opposite direction of Void's.


Bug Bug! Removed in Repentance Sacrificial Altar Sacrificial Altar is fully absorbed, unlike other single-use active items, allowing Isaac to sacrifice familiars and obtain Devil Room items with each activation of Void.
Bug Bug! If Isaac has overcharge from The Battery The Battery, using absorbed items that Isaac can "put away" (e.g. Shoop Da Whoop! Shoop Da Whoop!, Bob's Rotten Head Bob's Rotten Head, and Notched Axe Notched Axe) will use all the overcharge, even when Isaac puts away the items. In the case of Notched Axe on its own, using Void will use all charges at once.
Bug Bug! PC If Void had consumed Glowing Hour Glass Glowing Hour Glass, Isaac can still use Void to consume items by rapidly activating Void upon entering a room. This however causes Isaac to be unable to move, requiring the run be exited and resumed in order to continue playing.
Bug Bug! Pedestal items do not vanish instantly upon Void usage, allowing for an item to be obtained despite using Void on it. While the animation when using the Void prevents picking up pedestal items, this can be circumvented by cancelling the animation (e.g. using bombs or timed damage mechanisms like Shard of Glass Shard of Glass) or by having another player.
