Effects

Notes

  • If taking a Deal leaves Isaac with no health remaining, he can still survive by taking the Deal and then activating Satanic Bible, which will leave him at 1 black heart. This will only work if the Deal is a passive item, as trading Satanic Bible with an active item will make you unable to use it.
  • (in Repentance) Bosses with set drops aside from Boss Mom ingame.pngMom will still drop their normal item, but at the cost of one Heart Container.
  • (in Repentance) On XL floors, both items will become Devil Deals, even if Satanic Bible was only used once.
  • (in Repentance) Character The Lost icon.pngThe Lost, Character Tainted Lost icon.pngTainted Lost, and Character Tainted Jacob icon.pngTainted Jacob in his ghost form can safely take any Boss RoomBoss Room item pedestals and it has no effect on subsequent devil deals.
    • This also applies to the Lost form granted by the white fire on DownpourDownpour / DrossDross II. Taking a deal in this form will not remove hearts, making the player able to get at least 2 Devil RoomDevil Room items for free on that floor.
    • This does not affect the items dropped on The VoidThe Void.
  • (in Repentance) Using the Satanic Bible changes the Boss Room's item pool to the Devil Room item pool for purposes other than direct boss rewards as well. This works even if the boss does not normally drop items, such as Boss Mom ingame.pngMom, Boss Satan ingame.pngSatan, or Boss ??? ingame.png???.
    • Rerolls such as Collectible The D6 icon.pngThe D6, Rune of PerthroRune of Perthro, or Soul of IsaacSoul of Isaac will generate Devil RoomDevil Room items.
    • Using Satanic Bible after the Boss Room item has spawned, followed by any reroll, causes the new item to be drawn from the Devil Room item pool, but it will have no heart cost. Taking this item will not prevent Angel Rooms from spawning.
  • (in Repentance) In True Co-op, the pedestal's additional items will also be Devil deals, but be drawn from the Boss item pool.
  • (in Repentance) Using Satanic Bible on (in Repentance)DownpourDownpour / (in Repentance)DrossDross II will affect the Mirrored World Boss drop.
