Binding of Isaac: Rebirth Wiki

(except in Rebirth)

Charged Baby is a passive item added in The Binding of Isaac: Afterbirth.

Effects[ | ]

  • Spawns a battery familiar that, while the player is in an uncleared room, every 30 seconds, starting from the moment it has been picked up, does one of the following:

Notes[ | ]

  • Charged Baby becomes very powerful as Character Lilith iconLilith in Greed mode, as the duplicates will continue to spawn Lil' Batteries, leading to a huge chain of familiars.
  • (in Repentance) Familiars that follow behind Isaac have a certain priority in how close their position is to him over other familiars, with Charged Baby having the lowest priority at 6th and thus being farther from Isaac than familiars of different priorities.
  • In an uncleared room, if Charged Baby familiar has reached the maximum of spawned batteries and/or added activated item charges, Isaac may re-enter the room (e.g. by bombing a closed door, having (in Afterbirth † and Repentance)Door StopDoor Stop or (in Repentance)Collectible Mercurius iconMercurius) to reset Charged Baby's effect limits.
    • This effectively allows farming for batteries and activated item charges, given the player's patience, ability to avoid enemies present in the room, and a way to re-enter the room indefinitely.

Synergies[ | ]

  • Collectible BFFS! iconBFFS!: Familiar is bigger and drops Lil' Batteries more often. No effect on its other abilities.
