Box of Friends is an unlockable activated item added in The Binding of Isaac: Afterbirth. It is the starting item for Character Lilith icon.pngLilith.

Effect

  • Upon use, it adds one copy of each of Isaac's familiars for the duration of the current room.
  • If Isaac has no familiars, a Collectible Demon Baby icon.pngDemon Baby will spawn for the duration of the current room.

Notes

  • If Isaac has more than one copy of the same familiar, it will still only add one copy.
  • Blue Flies, Blue Spiders, and orbitals (Collectible Halo of Flies icon.pngHalo of Flies, (in Afterbirth † and Repentance)Collectible Leprosy icon.pngLeprosy, etc) are not copied.
    • (in Repentance) It now copies some orbitals.
  • Many familiars can be spawned in Greed mode and Boss RushBoss Rush, as completing waves charges the item.
  • (in Repentance) Familiars with the uniquefamiliar item tag are ignored by Box of Friends. If Isaac has only unique familiars, a Demon Baby is spawned.
  • (in Repentance) The item will cost 10 cents if found in a ShopShop
