Not to be confused with Satanic Bible.
The Book of Belial is an activated item.
Contents
Effects[]
- Gives +2 damage for the current room.
Guarantees the
Devil Room or
Angel Room to spawn after killing a boss while holding it.
Increases the chance to open the
Devil Room or
Angel Room after killing a boss by 12.5% while holding it.
This item belongs to the Bookworm set. Collecting three items from this set will transform Isaac into Bookworm.
Notes[]
-
Judas starts with this item by default.
The damage bonus does not stack with multiple uses in the same room or with
XV - The Devil.
Additional uses in the same room or combined with
XV - The Devil give +1 damage per use.
- While activated, switching items will end the bonus damage effect.
- If the
Schoolbag and a second activated item are held, the book must be equipped in the primary slot to receive the
Devil Room /
Angel Room bonus.
Only guarantees Devil/Angel Rooms on floors that they can normally appear on, and, unlike
Goat Head, picking up The Book of Belial after killing the boss will not open the Devil/Angel Room door.
Synergies[]
Blood of the Martyr: Causes The Book of Belial to apply a 1.5x damage multiplier on top of its normal effect. This multiplier cannot stack with multipliers from
Cricket's Head or
Magic Mushroom.
Book of Virtues: Spawns black and red wisps in the middle ring. Wisps deal double damage compared to normal wisps.
Car Battery: Gives +3 damage for the current room.
Judas' Birthright Combinations[]
While holding Birthright with
Judas or
Dark Judas, Book of Belial is able to be held alongside another active item, similar to
Book of Virtues. The book's damage bonus is equal to (2/3) * number of charges the overlaid item took to use. Items that do not require charges to use do not grant a damage bonus unless there is an exception listed below.
Certain active items also gain additional effects, which are noted below; any items not listed have their standard effects aside from the temporary damage up Birthright gives them.

Black Hearts and 1 item from the Devil Room item pool. If a Devil Deal has been taken, the payout is boosted to 3 Black Hearts and 2 Devil items.
Bag of Crafting: Collecting
Red Hearts,
Half Red Hearts or
Double Hearts with this item has a chance to transform them into
Black Hearts. When a heart is transformed in this way, a special sound plays and a black smoke puff appears. Does not work with

Razor Blade along with its original effect.
Book of Virtues: Can be stacked along with Book of Belial, allowing you to carry 2 passive books and an activated item on top of them.

- Increased durability: Each use of the axe has a very high chance not to use a charge.
- Faster usage: The axe can be swung up to four times per second, regardless of Judas' tears stat.
- Higher knockback: Enemies are knocked back when hit, receiving 8 + 0.2 * floor damage if they collide with a wall, obstacle, or other enemies.

- Increased luck: destroying obstacles with the axe has an increased chance to spawn pickups.
- Destroying
Poops will spawn pickups much more frequently. When combined with
Petrified Poop, the chance becomes 100% and will often result in multiple pickups from a single poop.
- Destroying Tinted Rocks will drop more consumables than usual, similarly to Super Special Rocks.
- Destroying Props (such as Urns, Mushrooms, Skulls, and Polyps) gives the prop an extra chance to drop its rewards. This can result in a single prop giving multiple drops.
- Destroying Fool's Gold rocks will drop significantly more coins.

Pandora's Box: In addition to the item's expected reward, spawns one of the following demonic familiars:
Blood Puppy,
Dark Bum,

Brimstone beam that destroys projectiles and deals more damage the longer it's active. The minimum damage is 2.25 + 0.24 * floor, and the maximum damage is 2.8 + 0.3 * floor, which it scales up to over the course of 3 seconds of continuous fire.
- Souls dropped from enemies are colored red, and the Urn displays a red graphic on the HUD when active.

Purgatory. The souls deal 2 * Judas's damage up to 3 times and destroy projectiles.
