Special Item

From Binding of Isaac: Rebirth Wiki
Jump to: navigation, search

Special items are items in the game that are considered stronger than normal by the developers. If the player sees a special item, even if the player has Curse of the Blind, subsequent special items have a chance of being re-rolled rather than being presented to Isaac, decreasing the likelihood of obtaining multiple special items on one run.

The list of special items is as follows:

  • Brimstone BrimstoneBrimstone Icon.pngTears are replaced by a laser beam that pierces through all enemies and obstacles in its path and deals high damage. Can only be fired after a short charge-up period.
  • D100 D100D100 Icon.png6 roomsUpon use, rerolls all passive items on Isaac like the D4, every pedestal item in the room like The D6, and every pickup like the D20.

Special Item Generation[edit | edit source]

When Isaac enters a room with an item in it, items are selected out of certain item pools depending upon the current room. Special items have a chance of being re-rolled depending on how many special items have been seen during the run:

Number of Special Items Seen Re-roll Chance
0 0%
1 50%
2 90%
3 98%
4 or more 99%
