(in Repentance)

Sulfur is an activated item added in The Binding of Isaac: Repentance.

Effects[ | ]

  • Upon activation, Isaac is turned into a demon and gains the effects of Collectible Brimstone iconBrimstone for the current room.
    • If Sulfur has already been used in the current room, it instead gives Isaac a 1.2x damage multiplier, +1 damage, and increases the size of the laser for the current room.
      • Further uses of Sulfur will increase Isaac's damage by 1.
  • This item belongs to the LeviathanLeviathan set. Collecting three items from this set will transform Isaac into Leviathan.

Notes[ | ]

  • Sulfur functions identically to Collectible Brimstone iconBrimstone. For a full list of interactions, see that page.
  • Sulfur is extremely powerful in Greed Mode.

Trivia[ | ]

  • Sulfur is from the Antibirth mod. Originally in Antibirth, due to a bug, using Sulfur twice in one room would permanently grant Brimstone to Isaac instead of giving him a more powerful brimstone laser.
    • This item originated in the "Binding of Isaac: Community Remix" mod for the original Binding of Isaac game.
  • "Sulfur" and "Brimstone" were once synonyms but the word "brimstone" has fallen out of use (outside of biblical usage).
  • Sulfur's appearance is based on the alchemical symbol for sulfur, although the triangle is upside-down and it lacks a small piece separating the cross from the triangle.
  • This item has the same pickup quote as Collectible The Nail iconThe Nail.
