Binding of Isaac: Rebirth Wiki

Added in Afterbirth

The Forsaken is a boss added in The Binding of Isaac: Afterbirth that can appear:


  • Spawns a Bony Bony.
    • While at least one Bony is still alive, the Forsaken becomes incorporeal and floats erratically around the room staying away from Isaac and very occasionally drifts towards Isaac attempting to pass through him.
    • Every tear shot towards the Forsaken during this phase passes through it.
    • When at around 30% HP, it spawns 2 Bonies instead.
  • When all Bonies are killed, The Forsaken moves close to the center of the room before reappearing and firing 3 Brimstone Brimstone lasers in triangular directions with one laser always shooting in the opposite direction of Isaac. These lasers then rotate just over 180 degrees in either direction.
    • Afterwards it stays vulnerable for a few moments before spawning another Bony and repeating the process.
  • Unlike its counterparts, The Haunt The Haunt and Added in Repentance The Heretic The Heretic, The Forsaken does not deal contact damage while incorporeal. Rather, if Isaac walks through The Forsaken, it spawns another Bony, briefly becoming vulnerable while doing so.
    • If this is repeated without killing any Bonies until there are 4 alive on-screen, the next time Isaac walks through The Forsaken, it performs a modified version of its Brimstone Brimstone attack with greatly increased speed and duration, killing off all Bonies.

Champion Versions Needs to be unlocked[]

Added in Afterbirth † Black: Spawns Black Bony Black Bonies instead of regular Bonies. The Spinning Brimstone attack is replaced with The Forsaken spawning 4 Dank Death's Head Dank Death's Heads and resuming invincibility for 1 second if there are no other Dank Death's Heads alive. It can not spawn any Dank Death's Heads if there is at least 1 other alive and will instead remain vulnerable for a duration before spawning another Black Bony.
