Trivia[edit | edit source]

  • This item originated from the Binding of Isaac: Community Remix mod.
  • Brimstone is an archaic name for Sulfur.
  • When this item was ported into Repentance, the effect to gain permanent Brimstone was fixed. However, as a possible nod to it, using it twice or gaining two Brimstones in any other way will grant a larger laser with higher damage and a unique costume.

Bugs[edit | edit source]

Bug Bug! If Sulfur is used while Isaac is shooting with Technology 2, the laser shot by Technology 2 will be locked in the current direction regardless of what buttons are pressed. Leaving the current room can fix this problem.
Bug Bug! Using Sulfur twice in a room grants its effects permanently. The effects remain even after Isaac gets rid of Sulfur.
