Added 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 (3 times per second).
    • The locusts may gain additional effects depending on the item destroyed[1].

Notes[]

  • 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.
  • Tainted Apollyon Tainted 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 familiars given by Soul of Lilith Soul of Lilith.
  • Using Abyss to destroy items in Boss Rush Boss Rush or Challenge Room Challenge Room counts as taking an item and causes waves of bosses or enemies to start spawning.

Synergies[]

  • BFFS! BFFS! / Hive Mind Hive Mind: Increases the locusts' size and damage by 25%.
    • These two items don't stack.
  • Book of Virtues Book of Virtues: Spawns wisps in the form of black-glowing flies with extra HP, that do not fire tears.
  • Death Certificate Death Certificate: Abyss can be used to absorb items without being kicked out of the area, allowing Isaac to instantly gain max locusts if used in a large room with enough items.
  • Extension Cord Extension Cord: Electricity will flow between Isaac and the locusts.
  • Ipecac Ipecac: Locusts gain +2 damage.

Interactions[]

  • Baby-Bender Baby-Bender / Box of Friends Box of Friends: Does not affect locusts.
  • Sacrificial Altar Sacrificial Altar: Locusts can be sacrificed for items.
  • Tainted Jacob Tainted Jacob / Tainted Lazarus Tainted Lazarus: Locusts will disappear when changing between the 2 forms, and will not return when switching back.
  • Void Void: 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 Void Void's appearance is in the opposite direction of Abyss's.

Bugs[]

Bug Bug! According to locusts.xml, Ipecac Ipecac locusts are supposed to explode. This never happens in game; Ipecac only gives a locust that deals slightly more damage and poisons enemies.

References[]

  1. Unique locusts and the items that give them are defined in locusts.xml. Every passive item in the game is listed in the file, but only the items mentioned actually have their locusts implemented.
