Sulfur is an active item.
- Grants Brimstone for the current room.
- If used twice in the same room (i.e. through the use of batteries), grants Brimstone permanently.
- 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.
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! Using Sulfur twice in a room grants its effects permanently. The effects remain even after Isaac gets rid of Sulfur.
