Effects[]

    • If Sulfur has already been used in the current room, it instead gives Isaac +1.8 damage for the current room and increases the size of the laser.
      • Further uses of Sulfur will continue increasing Isaac's damage.
  • This item belongs to the Leviathan set. Collecting three items from this set will transform Isaac into Leviathan.

Synergies[]

Trivia[]

  • "Sulfur" and "Brimstone" were once synonyms but the word "brimstone" has fallen out of use (outside of biblical usage).
  • Originally in Antibirth, due to a bug, using Sulfur twice in one room would permanently grant Brimstone to Isaac.
