Void

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

Effects

 * Upon use, destroys all pedestal items in the room.
 * If Void destroys an active item, it gains the 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.
 * If Void destroys a passive item, the player gains 2 random stat boosts. Possible stat changes include:
 * +1 flat damage
 * +0.5 tears and soft tear cap
 * +0.2 speed and maximum speed (may never exceed 2.0)
 * +0.2 shot speed
 * +1 luck
 * +0.5 range
 * If speed or tears are at their maximum and are chosen, there will be no visible increase.
 * This still applies to the tears stat in repentance, however it is more difficult to see as the hard tear cap has been increased to 120.

Synergies

 * Immediately grants invincibility frames.
 * Causes isaac to flash blue, but gives no invincibility frames.
 * : 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.
 * / : Allows it to be used every 6 rooms instead of 12 and batteries will fully charge the item.
 * : Allows the Eraser to be used multiple times per floor.
 * / : Using Void will cause both items to be absorbed.
 * + : Instantly spawns a Devil Room item if the holder has no familiars that can be duplicated Box of Friends.
 * Makes it significantly easier to use bombs to void and collect an item at the same time.

Interactions

 * Any single-use active item, such as /  /  /  / /  : Single-use items are used once upon being destroyed, but their effects are not absorbed and will not activate with subsequent Void uses.
 * Single-use items won't be used upon their absorption, but on the next usage of the Void, which allows to use the absorbed item later when needed. Their effects will still not be activated after the initial item effect.
 * is properly absorbed, unlike other one-time use items, allowing Isaac to sacrifice familiars and obtain Devil Room items with each activation of Void. Possibly a glitch or oversight.
 * Consuming Abyss simply overrides the Void's stat bonus/active item mimicking effect when used to consume another item, acting as a six-charge Abyss afterwards.
 * Void obtains the effect of the item, but can only be used once.
 * / : If an item that gives Isaac a new consumable is absorbed before these items, that consumable gets used instead, possibly resulting in nothing or a harmful effect.
 * + : Using the ? Card with an absorbed Blank Card has no effect at all. Isaac will not be teleported to the I AM ERROR room and the item and card are unaffected.
 * + : Invincibility from an absorbed Book of Shadows will not prevent damage by Blood Rights.
 * Broken Remote / /  /  /  with a teleport card /  with a Telepills: Items will still be consumed when Isaac teleports.
 * + : The item given will immediately be consumed for stats by Void.
 * If Void is either Isaac's only item or the item most recently picked up, it will be lost upon absorbing and thus activating the Clicker.
 * / : 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.
 * When absorbed and Void is used, replicates the effect of a random dice item.
 * Only replicates the effect of.
 * On the next use, the pedestal items in the room will be consumed but another copy of the items will be spawned afterward.
 * Consuming the Everything Jar will cause Void to spawn a poop when used, regardless of charge level.
 * : 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.
 * 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, or from consuming any further effects as Void will instead reset the room.
 * Be wary with this combination; without an infinite recharge, it is possible to jump to a spot that there is no way of returning from. (This can be fixed by going to the main menu and then resuming the game, however.)
 * Absorbing it with Void will not allow Isaac to pick up excess hearts.
 * Absorbing it with the Void will not allow the collection and generation of flies.
 * Each use will spawn only one wisp.
 * Drops a trinket every time the Void is used. The other passive effects of holding the box do not apply to the user.
 * Moving Box will not be added to Void; instead, it is converted into stat boosts like a passive item.
 * Absorbing it with Void will not give a passive ability to fly; however, Isaac will still charge in the first direction chosen.
 * 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.
 * A spinning top orbital will spawn every time the Void is used. The orbitals will last until Isaac leaves the room.
 * : Absorbing it with Void will not give a passive ability to fly. Isaac will still charge in the first direction chosen, but no beams of light will spawn.
 * Absorbing it with the Void won't do anything since the familiar you normally swap places with doesn't spawn.

Trivia

 * 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 effect on pickups was split to an entirely new item altogether.
 * Before the balance patch on 5 January 2017, Void synergized with single-use items and constantly 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 and Devil item pools, the others being, , and.
 * Void is the only Afterbirth † item with a quality of 4, besides and the Broken Shovel pieces.
 * The swirl in 's appearance is in the opposite direction of Void's.
