Head of Krampus is an unlockable activated item.


  • Fires a powerful 15►Brimstone Brimstone beam in the four cardinal directions, much like The Fallen and 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 19 ticks, dealing a total of 190 damage per use.
  • Damaging enemies with the effect of this item as 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 then a single beam.


  • Added in Afterbirth15►Car Battery Car Battery: Doubles the damage the brimstone beams deal (for a total of Removed in Repentance880 damage/Added in Repentance380 damage per use). Doesn't double the brimstone beams' duration.
