Binding of Isaac: Rebirth Wiki

Head of Krampus is an unlockable activated item.


  • Fires a powerful Brimstone Brimstone beam in the four cardinal directions, much like The Fallen The Fallen and Krampus Krampus shoot.
    • Added in Afterbirth / Removed in Afterbirth † Has a 50% chance to rotate all beams around the player 90 degrees, similar to Krampus' second Brimstone attack.


  • Removed in Repentance Each beam deals 22 damage per tick, and they tick a total of 20 times, dealing a total of 440 damage per use.
    • Added in Repentance Each beam deals 10 damage over 20 ticks, dealing a total of 200 damage per use.
  • Damaging enemies with the effect of this item as Guppy Guppy will spawn multiple Blue Flies.
  • By standing really close to large enemies such as bosses, it's possible to hit them with multiple beams at once, dealing significantly more damage than a single beam.


  • Added in RepentanceBook of Virtues Book of Virtues: Spawns red wisps in the middle ring. The wisps fire small Brimstone Brimstone lasers in the cardinal directions when destroyed. The lasers deal the wisps' tear damage per tick, and can hit up to 20 times. BFFS! BFFS! will not increase this damage, despite it scaling with the wisps' tear damage.
  • Added in AfterbirthCar Battery Car Battery: Doubles the damage the brimstone beams deal (for a total of Removed in Repentance 880 damage/Added in Repentance 400 damage per use). Doesn't double the brimstone beams' duration.
