Blue Map is an unlockable passive item.
- When combined with The Compass and Treasure Map, the entire floor is revealed, identical to the effect of The Mind.
- Blue Map does not display Ultra Secret Rooms.
- This item is used in Cursed! (challenge #10).
- In the original game, Treasure Map revealed the location of Secret Rooms as well. In Rebirth, this effect, along with the added effect of revealing of Super Secret Rooms, now belongs to this item instead.
