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 Brimstone for the current room.
  • 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.

Synergies

• Brimstone: One activation is enough to get the powered up version of Brimstone.
• Car Battery: Counts as double activation for the current room.

Interactions

• Dr. Fetus: Other than the costume, overrides Sulfur.

• Mom's Knife: Other than the costume, overrides Sulfur.

Trivia

• Sulfur is the more direct translation of Brimstone.
• Originally in Antibirth, using Sulfur twice in one room would instead permanently grant Brimstone to Isaac.
