BBF

### Collection Grid

*(page 3, column 7, row 7)**(page 3, column 7, row 2)**(page 3, column 8, row 2)*

**BBF** is a passive item.

## Effects

* Spawns a familiar that flies around the room like a Boom Fly and explodes on contact with an enemy, dealing 60 damage to all enemies within its blast radius and 10 damage to the enemy it touched.
* Deals 100 damage to all enemies within its blast radius and 10 damage to the enemy it touched.
	+ It will respawn 10 seconds after exploding, or upon entering a different room.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a giant humanoid fly.

## Notes

* Most obtained bomb modifiers are applied to BBF as well.
* The blast can damage Isaac as a normal bomb would.
* For the first few moments after entering a room, the familiar will do contact damage instead of exploding. This means the familiar will not blow up in Isaac's face if there is an enemy right next to the familiar's starting point. However, it may kill enemies that explode on death.
* If Delirium transforms into Larry Jr. and teleports on top of this item, it will take a lot of damage. With BFFS! even more (~60%).

## Synergies

* / : Doubles the contact damage to 20 and increases explosion damage by 25.
	+ Contact damage becomes 20 and explosion damage increases to 125.
* : The explosion damage increases by 50 points.

## Interactions

* : The explosion applies poison effect.
	+ Does not leave the poison cloud.
* : No cross explosions. Damage from the explosion is halved against the initial target, but others caught in the blast take full damage.
	+ Explodes in a cross-shaped pattern. Damage from the main explosion deals a flat 37.5 damage, and any additional explosion deals flat 75 damage to which Bomber boy's damage reduction is not applied.
		- Bomber Boy +  / : Explosion damages are increased to 1.25x, which are 46.875/93.75 each.
		- Bomber Boy + : Explosion damages are increased to 1.5x, which are 56.25/112.5 each.
		- Bomber Boy +  /  + : Explosion damages are increased to 1.75x, which are 65.625/131.25 each.

## Trivia

* The item's name is a reference to the acronym BBW, which stands for "Big Beautiful Woman".
A Card Against Humanity

"Something stinks..."

**A Card Against Humanity** is a special card.

## Notes

* Poop will not fill tiles with obstacles, even if they have already been destroyed.
* The process is not instant and the room will not get fully filled if Isaac leaves before it's done filling.
* It is more beneficial to use the card in a large-sized room as it will create more poop piles.
* Using A Card Against Humanity in the Ultra Greedier fight will result in Golden Poops spawning after defeating the boss.
	+ Results in Yellow Poops which only have normal drops.
* Using A Card Against Humanity in the Ultra Greed fight can trap the Greed Gapers after Key Coins appear, preventing Ultra Greed from attacking.

## Synergies

* : Spawned Poops have a high chance to turn into White Poop.
* Infested! pill: Every Poop spawns a Blue Spider.
* / ???: Every Poop spawns a Blue Fly.
* : Spawned Poops have a great chance to turn into Golden Poops.
* : Spawned Poops drop coins 20% more often.
* : Many spawned poops are black and can drop black hearts.
* : Pickup drop rate set to 50%. It's extremely likely to be obtained when using the card in larger, less obstructed rooms.

## Interactions

* : All the Poop explodes in a chain reaction once one is destroyed.
* /: If Isaac has no other means of destroying Poop than his explosive tears, he will have to hurt himself to clear out a path through the Poop unless he has acquired  or .

## Trivia

* The card is a reference to *Cards Against Humanity*, a satirical card game whose name in turn references "crimes against humanity". Specifically, it refers to the way the first player is chosen: Whoever was the last to poop goes first.
	+ This actually contradicts the original card game, as black cards are prompts while the white cards are answers to the prompt.
* In the pop-up (if not disabled) for unlocking this card, the text on it reads "A room full of poop".

## Bugs

If the poop is not destroyed before sleeping in Mom's bed then Isaac will have to stand below where the TV was teleported to in order to activate the Dogma fight. If Dogma is summoned before destroying the poop then the TV will glitch inside the Dogma fight and push Isaac around, possibly making him touch Dogma and get hit multiple times
Black Candle

**Black Candle** is an unlockable passive item.

## Effects

* Grants immunity to floor curses.
	+ Will immediately remove any curses on the current floor except Curse of the Labyrinth.

* Picking up this item during Pitch Black (challenge #1) will not remove the Curse of Darkness or Curse of the Unknown.
* Picking up this item during Ultra Hard (challenge #34) will not remove **any** of the curses.
* Picking up this item while under the effect of an Amnesia pill or ??? pill will remove the effect of the pill. However, the item does not negate the effects of Amnesia or ??? pills used after picking up this item.

* Picking up this item does not make the second item in alt floor treasure rooms visible.
* Doesn't remove Curse of Darkness afflicted by , no matter if Black Candle was picked up before or after using the card.

## Synergies

* : Grants a damage boost.
* : Removes teleportation effect of Cursed Eye.
* : Removes teleportation effect upon picking up a coin.
Basement

*(chapter 1)*

**The Basement** is one of the environments in Chapter 1. Unlocked at the beginning of the game, it is considered the easiest of the environments in the game. The theme of the Basement is flies and poop.

The Basement's harder unlockable variants are the Cellar and the Burning Basement.

 After  A Secret Exit is unlocked, a locked door similar to the one leading to a Treasure Room will appear in this floor's Boss Room upon defeating the boss, which leads to Downpour / Dross. Like a Treasure Room, this door requires a key to be unlocked. Unlike Angel Rooms and Devil Rooms, this door never disappears.

## Unlockable Achievements

* Monstro's Tooth - Beat Chapter 1.

* Something From The Future - Beat **Basement** 40 times.

* The Cellar - Beat all **Basement** bosses ( except Baby Plum) (not restricted to beating bosses *in* The Basement).

* Sprinkler - Beat Chapter 1 without taking damage.

* Basement Boy - Beat Chapter 1 without taking damage.

## Music

### Found In

The **Small Baby Long Legs** is a tiny variant of Baby Long Legs that simultaneously spawns Sacks along with a small puddle of slowing White Creep. The Sacks it spawns start at around half health and take a while to regenerate fully.

## Gallery

* Sketches of monsters for the Binding of Isaac: Rebirth, including what appears to actually be the Small Baby Long Legs in the sixth square of the first (called the Baby Long Legs in this sketch).

## Notes

* If a Small Baby Long Legs attempts to spawn a Sack on top of an already spawned Sack, the newly spawned Sack will replace the previous one.
Baby-Bender

**Baby-Bender** is an unlockable trinket added in *The Binding of Isaac: Afterbirth † (Booster Pack #5)*.

## Effect

* Grants Isaac's familiars homing shots.
	+ This includes the shots fired by  Lilith and  Tainted Lilith's attached familiar.

## Notes

* Using  with  will unlock this item.
	+ Tarot Cloth with the card has a unique effect and does not count as two uses for unlocking purposes.
* Using  twice in the same room will unlock this item.
* Baby-Bender applies to  whilst it is still in Isaac's head.

## Trivia

* Baby-Bender is based on this Steam Workshop item by Ink Toodles and ajudadoraAustera.

## Gallery

* Baby-Bender's appearance in the original Steam Workshop mod.
Attributes

**Attributes**, also known as **stats**, are the numerical values of a character that affect their performance and the behavior of their tears, the game's primary weapon. All characters start with a different set of values and they can be increased or decreased during a run. The seven main stats are:

* **Health**: The amount of damage the character can take before dying.
* **Speed**: How quickly the character moves.
* **Tears**: The character's rate of fire. The lower the number, the faster tears are fired.
	+ As of *Repentance*, Isaac's tear rate is shown in tears fired per second; the higher the number, the faster tears are fired.
* **Damage**: The amount of damage that each of the character's tears deals to enemies.
* **Range**: How long the character's tears will travel before landing.
* **Shot speed**: How quickly the character's tears travel.
* **Luck**: Affects a variety of chance-based effects.

Additionally, there are a few Hidden Attributes.

## Stat Screen

Most attributes can be viewed on the pause menu, except for health (which is shown in the game HUD). The pause menu's attributes are shown on an imprecise scale from 1 to 7 ( 0 to 7), and the values are as follows:

* Tear falling speed increases range stat in the pause menu by 1 for every 0.5 tear falling speed added.

The pause menu stat screen is made almost completely irrelevant by the introduction of the "Found Hud" feature in the *Afterbirth+* DLC. Once it is enabled from the in-game options, the player's stats will be displayed in numerical form below the key count.

## Found HUD

Some stats on the Found HUD are calculated and displayed differently from the internal, technical side of stats.

* **Damage**: Simply displays base damage per tear, without considering any special tear effects.
* **Tears**: Displayed as  "tear delay" or  "tears per second".
	+ To convert the internal tear delay to "Tears per second", use this formula:

	30

	Tear Delay
	1

	{\displaystyle \frac{30}{\text{Tear Delay} + 1}}

	.
* **Range**: Displayed as approximate  "tear lifespan" per tear or  "range in tiles".
	+ There is no straightforward conversion from tear lifespan to range in tiles, as tear falling speed and shot speed are also involved.
Analog Stick

**Analog Stick** is a passive item added in *The Binding of Isaac: Afterbirth †*.

## Effects

* +0.35 tears up.
* Allows tears to be fired diagonally.
	+ With a keyboard or using buttons to fire with a controller, tears can be shot at 45-degree angles by holding two buttons. This is known as eight-directional firing.
	+ With an analog controller, the analog input is accepted, allowing full analog aiming in any direction.

## Notes

* Enables full directional firing for keyboard and mouse users with the accessibility option `EnableMouseControl` enabled.
* /: When tears are fired diagonally, the split tears will also move diagonally.

## Interactions

* : Locusts cannot attack diagonally, and will attack upwards or downwards instead.
* : Summoned wisps are unable to shoot diagonally, and will shoot upwards or downwards instead.
* : When bone tears are fired diagonally, the bone shards will not always move diagonally.
* : No effect because missiles already can be fired in any direction.
* : Tears fired diagonally can retain the bonus fire rate, as long as Isaac’s head continues to face the same direction.
* : Incubus cannot fire in non-cardinal directions, only tears up applies.
	+ Incubus can now fire diagonally.
* : No effect because the tear can already move in any direction.
* : Overridden by Marked.
* : Only the tears up applies, since Mom's Knife already accepts analog input by itself.
* : Overridden by Tiny Planet.
* : Overridden by Tractor Beam.
	+ Tractor Beam now can be controlled.
Blister

This article is about the trinket. For the enemy, see Blister (Enemy).
**Blister** is a trinket added in *The Binding of Isaac: Afterbirth*.

## Effect

* Increases the knockback of Isaac's tears.

## Tips

* This trinket is useful against chasing enemies and enemies that explode upon death such as Mullibooms or Boom Flies.

## Synergies

* / : The knockback from Blister is stronger than from the items, and knockback boosts do not stack.
* : The beam pushes back enemies.
* : The controlled tear gains knockback.
* : The knife gains knockback.
* Piercing tears: Tears can again knock enemies back.
* /  /  / : Pushes the enemies back along the lasers. For Tech X, the direction is counter-clockwise around the ring.
* : Adds knockback, which can deal devastating damage to enemies caught in the blast.

## Trivia

* In real life, a blister is a small pocket of body fluid that forms within the upper layers of the skin.
Black Powder

### Collection Grid

*(page 4, column 15, row 3)**(page 4, column 15, row 3)**(page 4, column 16, row 3)*

**Black Powder** is a passive item added in *The Binding of Isaac: Afterbirth*.

## Effect

* Walking in a circle will spawn a pentagram symbol on the floor, which deals 10 damage per tick to enemies within it.
	+ This does not affect flying enemies.

## Notes

* The trail of black powder left on the floor will quickly disappear, meaning that there is an effective limit to the size of the pentagram that can be created, though bigger pentagrams can be created if the player has higher movement speed.
* The traced pattern does not have to be perfectly circular; closed shapes such as squares or very narrow crescents will work.

## Interactions

* : Although the powder trail is wider in appearance, it has no effect on how easily a valid shape is determined.

## Synergies

* : When the Ventricle Razor portals are placed on the opposite wall of a room and Isaac goes from one portal to another, a pentagram symbol can be created which covers almost the whole room.

## Trivia

* The pickup quote may be a reference to the Pearl Jam song of the name "Spin the black circle".
BFFS!

**BFFS!** is a passive item.

## Effects

* Visually increases the size of all familiars by 25%, and improves the effectiveness of most of them.
	+ Doubles the damage of Familiars that deal damage through tears and contact damage.
		- Has no effect on Creep generated by familiars.
	+ For pickup-generating familiars, increases the frequency that they drop pickups.
		- Familiars that require clearing a certain number of rooms will require one less room.
		- Familiars that have a random chance to drop items have a higher chance.
		- Familiars that pick up consumables require less, except  which is unaffected.
	+ Some familiars have unique synergies.

## Notes

* The size change is only cosmetic: familiars' hitbox for blocking damage or attacking is not affected.
* Familiars summoned by a trinket or by  are also affected by BFFS!.
	+ Wisps are also affected by BFFS!.
* The Blue Flies and Blue Spiders benefit from  instead.
* Does not increase the frequency or effectiveness of Status Effects applied by familiars.

## Synergies

* /: Doubles impact damage and increases explosive damage by 25.
* : Spawns 4 rock waves in an x pattern. Doubles the damage when the bird lands and doubles contact damage. Damage of waves unaffected.
* : Adds 2 extra full hearts worth of bonuses if any health is drained.
* : Double water damage and spawns a blue flame at point of impact.
* : Shoots tears that do  2x Isaac's damage  1.5x Isaac's damage. Still deals 2x as  Lilith.
* : Fires additional shots in random directions and leaves a larger puddle of creep. Does not change the heart's size.
* : Spawns an extra Blue Spider.
* : Increases the creep pool's size, but not its damage.
* : Gives the Lost Soul a  effect.
* : Spawns a champion variant of an enemy, even if the enemy normally can't be a champion.
* : On use, fires eight tears from Isaac's original location. The tears synergize with Isaac's tear effects.
* : The aura's radius increases, but the damage multiplier and damage to enemies remain the same.

## Interactions

* : Only increases the damage and size while it isn't hostile.
* : The eyes are not treated as familiars and therefore will not synergize with BFFS!
* /: Doesn't change the head's size, but still improves its damage.
* : Does not stack.
* : Retains the increased damage even after being absorbed.

## No Effect

The following familiars will appear larger, but gain no actual benefits.

## Trivia

* This item is used in The Family Man (challenge #19) and  Scat Man (challenge #36).
Adrenaline

**Adrenaline** is a passive item added in *The Binding of Isaac: Afterbirth †*.

## Effects

* Gives Isaac a flat damage up based on how many empty Heart containers he has.
	+ The damage up given is 0.2 for each empty Red Heart container Isaac has.
		- The damage up given is ((2 \* MissingHearts) ^ 1.6) \* 0.1, where MissingHearts is the number of full red hearts of health missing. The amount of damage gained this way is exponential, so each heart lost will provide a bigger bonus than the last.
	+ Damage ups are only applied for every fully empty heart container.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a buff berserker.

## Notes

* This item has no effect on characters that can't have any Red Heart containers, unless Bone Hearts are collected. If a Bone Heart is gone, so does the Adrenaline damage. This means that Adrenaline is only truly useless on  The Lost.
* This item affects both  Keeper and  Tainted Keeper; empty Coin Hearts increase damage.
* As  The Forgotten, empty Bone Hearts increase damage, but if the Bone Hearts are broken, the damage buff is taken away.
* The maximum damage bonus from Adrenaline is 14.05 normally, 16.15 with Bone Hearts, and 30.9 for Magdalene with Birthright.

## Synergies

* +  Magdalene: Allows Magdalene to have 6 more Heart containers.
* : Activates the damage up effect of Adrenaline for the resulting empty heart containers at the start of each floor.
* : Activates the damage up effect of Adrenaline if an empty heart container is granted at the beginning of each floor.
* : Allows Isaac to keep the damage up after refilling hearts.

## Trivia

* Before v1.06.0190, Adrenaline was named Adderline.
	+ Despite having its name changed, Adrenaline's item sprite is named collectibles\_493\_adderline in the game files.
* Adrenaline is a hormone produced by the body in situations of high stress that increases blood circulation, breathing, and other things in preparation for the natural flight or fight reflex.
* Adrenaline causes characters to have an animation that makes them look like they are breathing rapidly. The more health they're missing, the more exaggerated the animation is.
Big Fan

### Collection Grid

*(page 3, column 4, row 8)**(page 3, column 14, row 2)**(page 3, column 15, row 2)*

**Big Fan** is a passive item.

## Effects

* Spawns a large orbital familiar that blocks enemy shots and deals 2 damage per tick (~8.57 damage per second) on contact.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a giant humanoid fly.

## Notes

* The Big Fan is the largest of the orbital familiars, but also deals the least damage.  Its contact damage is tied with  and its position of the lowest contact damage has been usurped by  while Isaac's damage stat is low.
* The Big Fan has lower rotational speed than other familiars (similar to Blue Flies).
* The Big Fan orbits independently rather than occupying one of the three defense orbital slots.
* Affects the speed of all other orbitals, slowing them down a lot (NOTE: This effect does not happen until you get a new orbital after Big Fan).
* Horse pill versions of the Pretty Fly pill spawn a Big Fan without granting it as an item. Big Fans acquired this way spin at normal pace and don't affect rotation speed of other orbitals.

## Synergies

* / : Big Fan becomes visually larger and deals more damage. Collision radius is not increased, however.

## Interactions

* Orbital familiars: If Big Fan is the first orbital obtained, subsequent familiars will match its low speed.  This excludes Pretty Flies.

## Trivia

* Big Fan looks like a mixture of a Boom Fly and Gluttony.

## Gallery

* Big Fan appearance prior to Afterbirth.
9 Volt

**9 Volt** is a passive item.

## Effects

* Fully charges the currently held active item upon 9 Volt's first pickup.
* If the current active item has a recharge time of more than 1 bar, then it will grant 1 bar of charge whenever the item is activated.
* If the current active item has a recharge time of 1 bar, then it will change the item to have a timed recharge of 15 seconds. The recharging of the item only triggers so long as there are enemies present in the room in any fashion. Empty rooms do not cause recharging to start.
* If the current activated item already has a timed recharge, 9 Volt makes it start at half charge when used, effectively halving the time to recharge and allowing quicker reuse.

## Notes

* Enemies generated through a Slot Machine, Shell Game,  Hell Game,  Rotten Beggar or breaking Urns/Skulls will restart the charging process, even though a cleared room still counts as cleared if enemies are spawned in it.

## Synergies

* **2-bar items**: Fills the entire gauge in a single room, effectively granting the opportunity for the item to be used every room.
* **3-bar items**: Quadruple rooms and L-shaped rooms give 2 bars after clearing them, allowing one free use of the item in those rooms if the gauge is full upon entering them. It can also be used at the beginning of a Boss Challenge Room to get the full charges back after beating both bosses.
	+ + 3-bar items: Same as the 2-bar item synergy without AAA Battery.
* **4-bar items**: In a Challenge Room, if the item is used during the first wave, it will get all its charges back at the end.
	+ + 4-bar items: Same as the 3-bar item synergy without AAA Battery.
* Keeper: The  and the 9 Volt allow him to gain health (and money) forever, as long as there is an enemy in the room.
	+ An enemy spawned in a cleared room will also cause recharging to start.
* : The item can be reactivated the moment the previous charge stops, making it always active

## Interactions

* : No further decrease in charges.
* : No effect.
* : Prevents Dim Bulb from working, as minimum charge becomes 1 instead of 0.
* : No effect.
* / : The first bar gains an automatic recharge, but the further bars will not be affected.
* : Renders the Sharp Plug unusable on 2+ charge items. Sharp Plug can only be used if the item is at 0 charges, but 9 Volt instantly gives +1 charge to the item upon activation.
	+ Lowers the cost of using Sharp Plug by half a heart on 2+ charge items.

## Unlockable Achievements

* Extension Cord - Have , , and  in Isaac's collection.

* Jumper Cables - Pick up any 2 of the following items/trinkets in a single run: , , , , and  ( Any 2 items that have the 'battery' item tag).

## Trivia

Ball of Bandages

**Ball of Bandages** is an unlockable passive item.

## Effects

* Spawns an orbital familiar that deals contact damage.
	+ It deals 105 damage per second.
	+ It deals 52.5 damage per second.
* Unlike the , it does not block enemy shots.
* Ball of Bandages blocks enemy shots.
* Each subsequent Ball of Bandages obtained are combined with the first one (increasing its 'level'), changing its characteristics:
	+ Level 2: Gives the orbital the ability to shoot Charm tears that deal 3.5 damage.
		- It shoots once every second.
		- It shoots once every 0.73 seconds.
	+ Level 3: Changes it from an orbital to a Bandage Girl that that chases nearby enemies dealing contact damage and fires Charm tears in the direction Isaac shoots. The tears it fires are the same as the ones fired by the Level 2 form.
		- It deals 52.5 contact damage per second.
		- It deals 8.75 contact damage per second.
		- It deals 12.5 contact damage per second.

		- It deals 82.5 contact damage per second.
		- It deals 13.75 contact damage per second.
		- It deals 25 contact damage per second.
	+ The fifth Ball of Bandages will create a new Level 1 ball, and start the cycle again.

## Notes

* Multiple Balls of Bandages can be collected in a single run.
* The orbital orbits Isaac significantly faster, making it more effective at blocking shots but less effective for dealing damage.
* Famine, Pestilence, War, and Death will always drop either a Ball of Bandages or . After the first one drops, further Harbingers will only drop that same one and never the other for the duration of the run.
* The ticking rate for Bandage Girls' contact damage causes them to often deal damage twice once they touch an enemy, making their first second of DPS up to 1.5x higher than normal.
* Level 3 and 4 Bandage Girls' tears inherit Isaac's momentum.

## Synergies

* : Ensures that Harbingers that haven't already been defeated will replace their respective floor's boss, making it drastically easier to collect multiple Balls of Bandages.
* / : Additional copies of Ball of Bandages combine with the first, increasing its level as normal.

## Interactions

* : Familiar will stay in place relative to Isaac at levels 1 and 2. No effect at levels 3 and 4.
* Pretty Fly: Ball of Bandages will replace one if Isaac already has 3 Pretty Flies. If the Ball of Bandages reaches level 3 or 4, the Pretty Fly will come back until another Ball of Bandages orbital is obtained.

## Unlockable Achievements

## Trivia

* Bandage Girl is a secondary character in *Super Meat Boy*, a game by Edmund McMillen, the creator of *The Binding of Isaac*.
* Ball of Bandages item description of "Gotta Lick'em All" is similar the "Gotta Catch'em All" phrase in Pokémon.
Azazel's Rage

**Azazel's Rage** is an unlockable passive item added in *The Binding of Isaac: Repentance*.

## Effects

* Isaac builds up rage every time he clears a room, which is indicated by the patch of skin that spreads around his face, as well as the four sections of the horn lighting up red one at a time.
* After four rooms, Isaac's head will start to flash red; upon entering a room with enemies, he will fire a large  laser for ~3.33 seconds.
	+ The laser deals Isaac's damage per tick (15x Isaac's damage per second).

## Notes

* The counter for activation will go up during Greed Mode, Challenge Rooms, Boss Challenge Rooms and Boss Rush waves, as well as the waves in the The Beast fight.
	+ If the Brimstone laser is ready, it will fire automatically after clearing a Greed Mode or Beast fight wave.
	+ It will not fire in challenge rooms or boss rush.

## Trivia

* This item is, most likely,  Azazel's severed right horn.
* This item resembles one of the horns of The Beast.

Bloody Crown

**Bloody Crown** is an unlockable trinket added in *The Binding of Isaac: Afterbirth †*.

	+ Converts all Red Heart containers into Black Hearts, and adds 2 additional Black Hearts.
	+ Will not remove Bone Hearts, but will empty them.
		- The emptied Bone Hearts will not be converted to Black Hearts.
* Adds a chance to shoot fear tears.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into Leviathan.

100
−

⌊

L
u
c
k

⌋

{\displaystyle \frac{15}{100 - \left \lfloor \mathit{Luck} \right \rfloor}}

	+ At base Luck (0), the chance is 15%, maxing out at 100% at 85 Luck.
	+ is significantly better at inflicting fear than Abaddon.

	+ Sets  Keeper's Coin Hearts to 1.
* Bethany will be left with half a Red Heart with her other Heart Containers removed.

* In the Hebrew Bible, the name Abaddon is used as a reference to a bottomless pit, often appearing alongside the place of the dead (which is known as Sheol), meaning the land of the dead. The actual Hebrew word Abaddon (אבדון - pronounced *avadon*) means "doom".
* Abaddon is the Hebrew equivalent of Apollyon.
* In the *New Testament's* *Book of Revelation*, an angel called Abaddon is written as the king of an army of locusts; his name is first transcribed in Greek (Revelation 9:11 – "whose name in Hebrew Abaddon").
* Abaddon also shares its name with a level from Edmund's previous game *Super Meat Boy*.
* resembles this item's costume, but its effects are closer to .
Blood Clot

*For the trinket with a similar name, see Lil Clot.*
**Blood Clot** is a passive item.

## Effects

*The following stats are applied to tears from Isaac's left eye only.*

* +1 flat damage.
* +5 range.
* +2.75 range.
* +0.5 tear falling speed.

## Notes

* This item can rarely drop from polyps.
* The damage bonus is unaffected by both positive and negative damage multipliers.
* Azazel has a chance to fire a beam with the damage bonus. His range is unaffected.
* Cain has a 50% chance of firing a shot with the effects of Blood Clot whenever he fires since he can only shoot from his right eye.
* The Forgotten has a chance for Blood Clot effects to apply to his melee or ranged attack. When Blood Clot effects are applied the bone will turn red. When throwing the bone club, his range seems to be unaffected.
* Every other set of tears  Keeper fires contains the Blood Clot effect.
* applies to the same eye and the effects stack.
	+ Generally, every interaction and synergy that applies to Blood Clot also applies to Chemical Peel. See its page for a full list, with only differences listed here.

## Synergies

* /: The damage of Blood Clot is unaffected by the damage multiplier, significantly increasing DPS.
* : Turns all bombs red and increases their damage.
* : Missiles have a high chance to deal 20 points more damage with a red explosion.
* : The tears in the Lead Pencil barrage will always have the Blood Clot effect.
* : Effect is applied every time you shoot.
* : Orbiting tears will be the same as the last fired tear before leaving the previous room. To guarantee orbiting tears with the Blood Clot damage bonus, your last fired tear before leaving a room must come from the left eye.
* : As the laser from Technology 2 occupies your right eye, all tears now fired from the left eye have the statistical benefit of Blood Clot applied.
* : Blood Clot applies on both eyes, meaning the second shot from either eye will always be a Blood Clot shot. It will randomly alternate which shot of the two eyes counts for the other's Blood Clot shot if you fire multiple tears per shot like with Cursed Eye.

## Interactions

* : Incubus is not affected by Blood Clot.

## Trivia

* A blood clot is a bodily process that prevents excessive bleeding by forming a clot where the immense blood flow is, but can be harmful if it blocks an important passageway to a body organ.

## Gallery

* 3DS The icon of Book of Secrets as seen on the lower 3DS screen.

## Trivia

* This item may be a reference to an Apocryphon, or 'secret book'. This term is used to refer to early Christian writings that were written to teach 'secret knowledge' that wasn't allowed to be publicly taught.

* Prior to *Repentance*, this item's description was "??????"
Birthright

**Birthright** is an unlockable passive item added in *The Binding of Isaac: Repentance*.

## Effects

* Grants a passive ability that varies from character to character. The effect typically enhances/magnifies the character's special traits or helps mitigate some of their downsides.

## Notes

* Birthright effects are stackable when playing as  Tainted Lost,  Tainted Bethany, or  Tainted Magdalene. However, collecting additional Birthrights with Tainted Magdalene will simply add another bleeding heart container.
* Playing as  Magdalene, having more than 12 hearts, and entering the area in which  can be acquired will completely remove all hearts above 12.
* Playing as  Keeper, having 4 coin hearts and entering the area in which  can be acquired will set your coin hearts back to 3. Picking up a health-up item can bring you back up to 4 coin hearts.
* While playing as  Tainted Cain in Greed Mode, purchasing an on-sale item over and over while having Birthright results in almost infinite consumables.

## Interactions

* +  Tainted Eve: Clots won't drop half red hearts after getting sacrificed.

The following familiars are unaffected by  Tainted Lilith's Birthright:

* All orbitals
* Damage-triggered familiars (, etc.)
* Bouncing familiars (, etc.)
* Wandering familiars (, etc.)
* Mimicking familiars (, etc.)
* All familiars spawned by active items

## Trivia

* Birthright is from the *Antibirth* mod.
	+ Before *Antibirth* the item originated from the *Binding of Isaac: Community Remix* mod, where it was known as 'Soul Script'.
* This item's name, description, and unlock requirement are likely a reference to the biblical story of Jacob and Esau, in which Esau trades his birthrights to Jacob in exchange for stew.
	+ When  Tainted Jacob picks up Birthright, Dark Esau, a representation of his own rage, seemingly becomes only angrier and doubles in power.
		- Birthright's effect doubling Dark Esau's power, instead of Tainted Jacob's, further reflects the fact that it was originally his.
* Prior to patch V1.7.6, Tainted Jacob's Birthright pickup quote was "*There is no escape*".
* Tainted Keeper's pickup quote could be based off the song made by ABBA, "Money, Money, Money"
* Tainted Forgotten's pickup quote may be a play on words, as for recall can also mean to remember.
* Eden's Birthright could be a reference to how Eden functions in the card game *The Binding of Isaac: Four Souls,* as Eden starts the game by drawing 3 treasure cards and selecting one to keep permanently while the other two are discarded.
Abel

**Abel** is an unlockable passive item.

## Effects

* Spawns a familiar that mirrors Isaac's movements and shoots tears that deal 3.5 damage.

	+ Abel shoots tears towards Isaac regardless of which direction Isaac is shooting.
	+ When used by  Cain or  Tainted Cain, Abel's tears are red and deal 7.5 damage.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a three-faced version of himself.

## Notes

* Although it is difficult to hit enemies with Abel, he can be useful in certain situations. Doples and Evil Twins can be easily taken care of without risk of damage using Abel. Abel can also assist in killing slow or stationary monsters that happen to be around the center of the room.
* In symmetrical room layouts Abel can be used to clear away destructible obstacles such as fire places and poops.

## Trivia

* According to the Bible, Abel was one of Adam and Eve's children and was the first human to ever be murdered. He was an opposite to his murderous brother Cain, which may explain the mirrored nature of this item. Also, this item is unlocked by defeating The Lamb with Cain, which makes the connection with the Bible more obvious.
* This item was originally unlocked in *Wrath of the Lamb* by defeating Isaac as Cain.
