Binding of Isaac: Rebirth Wiki

(in Repentance)

Abyss is an unlockable activated item added in The Binding of Isaac: Repentance.

Effects[ | ]

  • On use, destroys all items on item pedestals in the room and gives a unique red locust familiar for each item destroyed.
    • These locusts are permanent once created, up to a maximum of 64, after which creating more will replace older locusts.
    • The locusts loosely follow Isaac similarly to regular Blue Flies, charging in the direction Isaac is firing until hitting an enemy, wall, or certain obstacles like key blocks, dealing Isaac's damage per tick (2-3 times per hit).
    • The locusts may gain additional effects depending on the item destroyed.[1]

Notes[ | ]

  • Using Abyss in the ShopShop or the Devil RoomDevil Room will not give you any locusts nor destroy any items that have not been purchased.
  • In rooms where there are multiple items to choose from, using Abyss will give only one locust for each item choice/set.
  • If already at the maximum amount of locusts and presented with multiple non-choice item pedestals, using Abyss will only consume half of the pedestals.
  • Character Tainted Apollyon iconTainted Apollyon starts with this item in the consumable slot.
  • If Abyss is used while Isaac is holding an item above his head, it can still consume the item and grant a locust.
    • This mechanic can be used to destroy bought items, unwanted blind items as well as familiars given by Soul of LilithSoul of Lilith.
  • Using Abyss to destroy items in Boss RushBoss Rush or Challenge RoomChallenge Room counts as taking an item and causes waves of bosses or enemies to start spawning.
  • Locusts granted by Abyss are not taken away during the sequence to obtain the Collectible Knife Piece 2 iconKnife Piece 2. Mother's Shadow cannot be harmed, but they can help destroy Fire Places blocking the path faster.
  • Locusts granted by Abyss are nearly irremovable, only Collectible Genesis iconGenesis can completely remove all locusts from a character. Collectible Sacrificial Altar iconSacrificial Altar and exceeding the familiar limit can remove some locusts. Reroll effects such as Collectible D4 iconD4, Character Tainted Eden iconTainted Eden taking damage, Collectible Missing No. iconMissing No., etc. cannot remove locusts.
  • In Repentance Co-Op if a player dies, any of the special locusts they have will persist, following and attacking from their ghost.

Interactions[ | ]

  • Baby-BenderBaby-Bender / Collectible Box of Friends iconBox of Friends: Does not affect locusts.
  • Collectible Car Battery iconCar Battery: No effect.
  • Collectible Death Certificate iconDeath Certificate: Only allows the consumption of one item per Death Certificate room and the consumed item is treated as if it was picked up causing all other items in the room to disappear and forcing Isaac to leave the area.
  • Collectible Genesis iconGenesis: The locusts created by Abyss are removed without creating items to replace them.
  • Collectible Sacrificial Altar iconSacrificial Altar: Locusts can be sacrificed for items.
  • Collectible Void iconVoid: If Void consumes Abyss, the latter will take priority and using Void to consume another item pedestal will generate a locust. Even consuming active items will generate a locust, and Void will not copy that active item's effect. This essentially causes Void to act identically to Abyss, albeit requiring 2 more charges per use. Stats and effects of the active items absorbed prior to consuming Abyss are kept and will trigger everytime Void will be used.

In-game Footage[ | ]

Trivia[ | ]

  • The way that Abyss works is similar to how it's described in the Book of Revelation, where locusts emerge from the Abyss and are controlled by Apollyon.
  • The swirl in Collectible Void iconVoid's appearance is in the opposite direction of Abyss's.

Bugs[ | ]

Bug Bug! According to locusts.xml, Collectible Ipecac iconIpecac locusts are supposed to explode. This never happens in game; Ipecac only gives a locust that deals slightly more damage and poisons enemies.
Bug Bug! Each use of Collectible Glowing Hourglass iconGlowing Hourglass that does not move Isaac to a different room than the one he is currently in (such as the starting room of a new floor) will duplicate the locusts.
