Abyss

Effects

• When used, destroys all items on item pedestals in the room and gives Isaac 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.
    • This limit is shared with blue flies and blue spiders.
  • The locusts loosely follow Isaac similarly to regular blue flies, and charge in the direction Isaac is firing until they hit an enemy, a 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.

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 he dies and is revived as another character (e.g. through Ankh), that character will retain the locusts.
• If Abyss is used while Isaac is holding an item above his head, it can still consume the item and grant a locust.
• Using Abyss to destroy 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.

Synergies

• BFFS! / Hive Mind: Increases the locusts' size and damage by 25%.
  • These two items do not stack.
• Book of Virtues: Spawns wisps in the form of black-glowing flies with extra HP, that do not fire tears.
• 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.

Interactions

• (Baby-Bender) Baby-Bender / Box of Friends: Does not affect locusts.
• Ipecac: Locusts will only gain +2 damage.
• 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: 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.

Bugs

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