Beans!

**Beans!** is Challenge #13. Isaac starts off with , , , , and . The goal is to defeat Mom. This Challenge is available by default.

## Difficulty

* Isaac starts the challenge blindfolded so he cannot fire tears. Most enemies will be killed using poison.
* If Isaac is running out of bombs, it is advised to restart the challenge as there is a high chance of enemies spawning out of Isaac's reach of his attack.
* Brownie is nearly guaranteed to end a run. He can't take poison damage and Butt Bombs will heal him.

## Strategy

* The Bean has a short-range and needs 15 seconds to recharge before it can be used again. This makes it rather ineffective, so exchanging it for a more effective item such as , , , , or  is advised.
* Should  or  be found in a devil room, do not pick it up as it will create no effect.
* Butt Bombs are more valuable than The Bean as a weapon since one bomb can confuse and slightly damage every enemy in the room while dealing high damage to any enemies caught in the blast. This is especially important when enemies can not be reached to damage directly.
* Buying bombs in Shops is important. However, buying  or the  will provide higher returns in the long run.
* The  card is an extremely valuable resource as it allows a far more liberal placement of bombs. A bomb count of 49-50 will get the most out of the card's effect.
* The Bombs are Key pill will be a major problem for the duration of the challenge. It is possible to counter the effect by using the pill again, but it is advised not to rely on that.
* It may also be effective to have  as it would allow Isaac to both concentrate multiple bombs to easily kill a boss and would also greatly reduce the chance of taking damage from a stray bomb.
* If running low on bombs, it may be wise to look for familiars, as they could help with some extra damage.  Powerful familiars such as  and  can make the challenge much easier.
* are invaluable, as they will allow the player to restock on bombs by collecting defused Troll Bombs. Together with  it will ensure the player will never find themselves without bombs, as long as they can afford to take damage, while the  will give a quick and steady refill of bombs thanks to 9-Volt.
* Getting a  or  will allow the player to get past Brownie should he spawn.
* Getting  will increase the chance of finding bombs.
* Getting an orbital such as  on the first floor can provide a more reliable source of damage than the starting items.

## Item Synergies

* : Troll Bombs spawned retain Butt Bomb damage, and item recharges every other room. While The Bean's multiple uses per room are lost, conserving bombs become much easier as the book can wipe out most enemies in a single room in one shot.
* : Works basically as a free combat bomb every 10 seconds, with the bonus of having poison damage. Can be fired with the blindfold on, providing a decent ranged option apart from normal Butt Bombs.
* Items that grant bombs such as  and  can be useful to avoid running out of bombs.

## Reward

* Burnt Penny - Complete **Beans! (challenge #13)**.
Bestiary Repentance

The **bestiary** is a new addition to *The Binding of Isaac: Afterbirth †* that is accessible through the "Stats" menu. The Bestiary shows information and statistics on all encountered monsters and bosses except for some alternate forms of some enemies.

It shows the number of times an enemy has been encountered, how much health it has, how much damage it has done to Isaac, how many times it's been killed, and how many times it has killed Isaac.

Because *Repentance* added a lot of new enemies, the whole page layout was reworked, requiring this page to be separate from the *Afterbirth †* Bestiary.

## Notes

* The order of the monsters starts with *Rebirth* enemies, then *Afterbirth* enemies, then *Afterbirth †*, and finally *Repentance* enemies.
* Encountering a boss while fighting Delirium does not count towards the bestiary.
* Seeded and challenge runs will affect bestiary entries, including whether an enemy has been found at least once or not, meaning that regardless of whether achievements are disabled or not, bestiary entries will still be updated.
	+ This also means that enemies spawned using the developer console will be counted as well.
* While fighting Hush, the Blue Boil will count as an encounter but the Blue Gaper will not. A Blue Gaper must be found on its own to be marked as an encounter.

## Pages

These are the monsters on each of the bestiary's pages.

*(Click on the images to open the corresponding monster page.)*

## Unlockable Achievements

* Sin collector - Collect every entry in the Bestiary (bugged v190 - Mobs that don't exist in the bestiary are being counted. This allows Sin Collector to be unlocked without a complete bestiary).

## Trivia

* Cross Stoneys are not featured in the Bestiary because they only appear in the Aprils Fool challenge and were added as a joke by \_Killburn revealed in a tweet made on April Fools Day.
* Henry has no bestiary entry.

## Bugs

* For Pin, The Frail, and Scolex, each body part counts as an encounter and a kill.
* For Larry Jr. and The Hollow, only their heads count as a kill but each part counts as an encounter.
* Satan, War, The Matriarch and Dogma kills are not registered.
Bloody Penny

**Bloody Penny** is an unlockable trinket.

## Effect

* Gives a chance to drop a Half Red Heart when money is collected.
	+ 50% chance.
	+ The chance is based on the coin's worth:

 Dime | 94.37%

## Notes

* It can be found by destroying Special Shopkeepers.
* This trinket is very useful in Greed mode, as the coins dropped for completing a wave now provide health.

## References

1. ↑ The chance is calculated as 1-0.75(coin\_worth)

* If encountered in a Double Trouble boss fight, its  laser can damage the other boss.

## Effects

* Chains down the nearest enemy, completely preventing them from acting for 5 seconds.
	+ This effect works on enemies that are invulnerable as well, and can alleviate a lot of stress from most trap rooms.
	+ If used again, it releases the enemy early.
	+ If multiple enemies are chained down at once, the enemy released early will be the one closest to Isaac even if Dark Esau is chained down too.
* While playing as  Tainted Jacob:
	+ Anima Sola will always target Dark Esau if he is present.
	+ While Dark Esau is chained down, using Anima Sola again will release him and cause him to charge directly at Tainted Jacob, damaging and burning enemies in its path. This will not use up additional item charges.
	+ Dark Esau deals no contact damage to Jacob while chained down.
	+ If used in a room with no enemies, Anima Sola will immediately summon Dark Esau.
	+ If  is obtained, the recharge time is lowered to 10 seconds and the chain duration is increased to 6.67 seconds.

## Notes

* Enemies other than Dark Esau can also be released. This will not cause them to do anything special.
* If The Visage's mask is chained down when it runs out of HP, it will outright die instead of becoming temporarily inactive, leaving only the heart to be fought. It is unknown if this is a bug.
* If Mom's Heart/ It Lives is chained down before it can spawn the Eyes at the beginning of the fight and is damaged enough to advance a phase by the time the chains break, the Eyes will not spawn.
* Delirium will stop shapeshifting when chained.
* If an enemy is in the middle of attacking with tears, their tears will still be fired after the effect ends. This happens even if the enemy has zero HP by the end of the ability.
* If used against The Beast during her chase attack, the destructible pillars will stop spawning until the effect ends.

## Synergies

* : Halves recharge time, allowing for chaining enemies much more frequently.
* : Spawns a dark wisp that orbits the locked enemy and shoots at them. When the enemy dies, the wisp despawns.
* : Two enemies will be chained simultaneously. If only one valid enemy is present, it will be chained for twice the duration. Using Anima Sola again will unchain the enemy closest to Isaac first.

## Trivia

* "Anima Sola" translates to "Lone Soul" or "Lonely Soul" in Latin. In a Christian context, it refers to a lone soul stranded and suffering in purgatory.
	+ The most popular depiction of this concept also involves both a chain, binding the lone soul's hands, as well as flames, like those following Dark Esau.
		- A splash of color in the chains can also be seen in the Anima Sola's icon, depicting said flames.
* The Anima Sola shares its name with an enemy from one of Edmund McMillen's other games, *The End is Nigh*. [1]

**Blue Key** is an unlockable trinket added in *The Binding of Isaac: Repentance*.

* Rooms that require money to enter (Arcades or rooms affected by ) can also be opened for free.
* Doors that require two keys to open, such as Vaults or Dice Rooms, will be opened instantly instead of waiting for the animation of both keys to be used.
* The door leading to Hush will also produce a blue room, despite not requiring a key.
* Isaac can unlock the rooms with Blue Key, but not enter them straight away. By exiting and re-entering the room, he can pass through the door that was unlocked with the Blue Key without having to go through the room in between.

## Synergies

* / : The blue room can be exited without fighting the enemies, and the door will remain unlocked.

## Interactions

* : Doors opened via explosions will not spawn the corridor.
* : Any portals inside the hall will be deleted upon exiting. While in the hallway, any portals to the outside can still be taken.

## Trivia

* The trinket might be a reference to SCP-860, a fictional key that acts in a near-identical manner.
* If used on the ??? floor, one might hear the mid-combat layer of the floor's theme, Nativitate, an asset which was previously unused.
Bishop

### Found In

**Bishops** are stationary enemies added in *The Binding of Isaac: Repentance*. They appear only in Mausoleum and Cathedral.

While a Bishop is alive in the current room, all other enemies that aren't Bishops will be given shields, protecting them from all damage taken; all Bishops in the room must be killed for the other enemies to take damage as normal. Additionally, when Bishops take damage, they retaliate by firing shots in the cardinal directions.

## Notes

* Bishops will not protect other enemies while petrified.
* Bishops will shield Isaac if he takes damage while they are charmed.
* When captured by , the Bishop will shield Isaac, but unlike with enemies, blocking damage done to Isaac damages the Bishop.
* Bishops cannot be healed by Pulsing Vivid Red Champions.

## Trivia

* In *Antibirth*, Bishop's robes had a purple color, didn't shoot tears after taking damage, had a base hp of 5, and could appear in Chest.

## Gallery

* Bishops in *Antibirth.*
* Concept art of the Bishop for Antibirth along with another monster concept art that presumably never got past development.
Bob's Curse

**Bob's Curse** is a passive item.

3 Dollar Bill

**3 Dollar Bill** is a passive item.

## Effects

* Grants Isaac random tear effects. The possible effects are:

* The type of randomized tear is determined upon entering a room.
* The type of randomized tear changes every 2–3 seconds. The item appears to select two tear effects at once, perhaps staggering the times at which each of those effects change.
* While not directly a tear effect, 3 Dollar Bill may rotate through , which may be used to take only positive pills.
* 3 Dollar Bill may also rotate through .

## Notes

* If a run is quit, and then continued, 3 Dollar Bill will have a new random tear effect for the current room.
* Items that are required to charge like  or  can have their charge amount change when gaining a new tear effect, depending on Isaac's new Tears stat. This can cause fully-charged items to need more charge time.
* The  effect is bugged for 3 Dollar Bill, and will only fire half the range it would normally (damage is increased normally).
* Unlike , which can only modify individual tears, 3 Dollar Bill can modify stats as well.

## Trivia

* This item is a reference to an old expression "queer as a three dollar bill".
* This item is used in  PRIDE DAY! (challenge #28).
Bobby-Bomb

**Bobby-Bomb** is a passive item.

## Effects

* Grants 5 Bombs.
* Bombs home in on enemies.

## Effects

* Spawns a controllable familiar that damages enemies on touch. It can be moved using the shooting directional keys, similarly to  and .
	+ ???'s Only Friend deals 2.5 damage per tick, and ticks 15 times a second, dealing a total of 37.5 damage per second.

* This item belongs to the  set. Collecting three items from this set will transform Isaac into a giant humanoid fly.

## Notes

* Unlike The Ludovico Technique, it cannot be controlled with the mouse, even with mouse control enabled.
* Holding two opposite fire keys (both left and right or both up and down) at the same time will keep the familiar in place, while making Isaac fire in the direction of whichever fire key was pressed second.
	+ This can help during combats with bosses who do not move a lot, as the familiar can continuously damage the boss when kept stationary.
	+ On some keyboards, holding opposite fire keys may cause other keys to become unresponsive.

## Gallery

* ???'s Only Friend's in-game appearance before Repentance.
* ???'s Only Friend's in-game appearance.

## Effects

* Spawns a fly familiar that orbits around a random enemy and deals 2 damage per tick/30 damage per second to enemies it comes in contact with.

	+ If the enemy it is orbiting dies, it starts orbiting a different enemy.
	+ If there are no enemies, it orbits Isaac.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a giant humanoid fly.

## Notes

* Angry Fly will orbit around invincible enemies such as Stone Grimaces without dealing damage.
* Due to its movement pattern, its actual damage dealt per second is erratic against most enemies and groups of them.
* As  Tainted Jacob, Angry Fly will orbit around Dark Esau.

## Gallery

* Angry Fly's original appearance prior to Booster Pack#4.

## Trivia

* Angry Fly is based on this Steam Workshop item by Custom Phase.

**Act of Contrition** is a passive item added in *The Binding of Isaac: Repentance*.

## Effects

* +0.7 tears up.
* Grants an Eternal Heart.
* Allows Isaac to take a Deal with the Devil without being locked out of Angel Rooms.
* Increases the chance for a deal to appear by 40% if Isaac has taken Red Heart damage.
	+ Additional 15% is added if Red Heart was taken against the boss.
	+ Both bonuses are applied after the normal penalty for damage, effectively mitigating them to -24% instead of -64% for taking damage during the stage, and to -44% instead of -99% for taking damage against the boss.

## Trivia

## Notes

* This item can drop from Pride.

* The Troll Bombs created by Anarchist Cookbook spawn in one at a time; if Isaac leaves the room soon after using it, not all 6 Troll Bombs will spawn.
* Using this item without any blast protection is not always recommended as it is very easy to be caught in the blast.

## Synergies

* : Spawns wisps in the middle ring, looking like bombs. The wisps spawn Troll Bombs when destroyed. These troll bombs will use Isaac's bomb synergies.
* : Each troll bomb has a chance to spawn a pickup or a trinket including batteries for repeated use.
* : The Troll Bombs generated will not explode until Remote Detonator is activated, unlike regular Troll Bombs.
* : Spawned troll bombs become bomb pickups.
* : Spawned bombs can be used for mass healing.

* : No effect.
* : Not recommended. Each Troll Bomb will spawn several smaller bombs upon exploding, making it very hard to avoid taking damage.
	+ No visual change can be seen with the Troll Bombs, but the smaller bombs have the sprite of the smaller normal bombs.

## About the Game

The Binding of Isaac: Rebirth is a randomly generated action RPG shooter with heavy roguelike elements. Players will accompany Isaac on a quest to escape his mother, facing off against droves of mysterious creatures, discovering secrets, and fighting fearsome bosses. Along the way, Isaac can find bizarre treasures that change his form and give him super-human abilities. But it won't be easy!

Rebirth is the remake of the original game that sports a game engine that runs at 60 FPS, pixelated style artwork, polished visual effects, and a new soundtrack from Ridiculon. Oh yeah, hundreds of new rooms, synergies, and retuned enhancements by the series creator, Edmund McMillen and other developers. There are three DLCs available for Rebirth,  The Binding of Isaac: Afterbirth,  The Binding of Isaac: Afterbirth † and  The Binding of Isaac: Repentance. Did we mention the poop?

Blood of the Martyr

**Blood of the Martyr** is a passive item.

## Effects

* +1 damage.
* Isaac's tears become red.

## Synergies

* : When Isaac uses Abyss to absorb Blood of the Martyr it turns into a red locust dealing double Isaac’s damage per tick.
* / : Applies an additional 1.5x damage multiplier.
	+ The x1.5 damage multiplier does not stack with the x1.5 damage multiplier from  and .

## Interactions

* : No further effect when multiple copies of the item are acquired.

## Trivia

* This item is a reference to the book of Revelations: *And I saw the woman drunken with the blood of the saints, and with the blood of the martyrs of Jesus: and when I saw her, I wondered with great admiration. **-Revelation 17:6***
* This item's appearance is a reference to the crown of thorns placed upon Jesus Christ's head during His crucifixion.
2Spooky

**2Spooky** is a passive item added in *The Binding of Isaac: Repentance*.

## Effects

* Applies fear to enemies in a small radius around Isaac.

## Notes

* 2Spooky can be used to manipulate Ultra Greed. Once Greed Gapers spawn and Ultra Greed is in his resistance stance, the gapers will be feared when getting close, leaving the boss unable to move or damage Isaac.

## Interactions

* Tainted Forgotten: Not recommended, the fear aura makes it more difficult to hit enemies with Tainted Forgotten and does not provide protection to  Tainted Soul.
* : Overrides 2Spooky.

## Trivia

* 2Spooky is from the *Antibirth* mod where it would also comsetically change Isaac's tears to red and originates even earlier from the *Community Remix* mod for Flash Isaac.
* The name and pickup quote are a reference to the "2spooky4me" meme. Isaac's appearance also makes him appear similar to popular internet horror images, such as Squidward's Suicide and Giygas from Earthbound.
Blue Baby's Soul

Redirect to:

* ???'s Soul
Don't delete this page, it was created purposely as a redirect with the purpose of fixing the Trinkets page, as there was an issue in which the creator had mistakingly linked Blue Baby's Soul when the correct name, and page of the item was "???'s Soul" And as I couldn't find a workaround, I made this. If you can figure out how to make it work, feel free to delete this. Thanks

Betrayal

### Collection Grid

*(page 4, column 6, row 2)**(page 4, column 6, row 2)**(page 4, column 7, row 2)*

### Unlock Method

 Defeat Hush as  Judas

**Betrayal** is an unlockable passive item added in *The Binding of Isaac: Afterbirth*.

## Effect

* Upon taking damage, all enemies in the room are charmed.
	+ It won't trigger if there are less than 2 enemies in the room.
* Enemies are able to damage each other with projectiles. If an enemy is damaged by another enemy, they will attack that enemy instead of Isaac.

## Notes

* This item is extremely strong against the second and third phase of ???, as its own eternal flies become charmed and deal massive damage to the boss, often killing it after even just two uses.
* The initial effect only affects projectiles. Enemies will not deal contact damage to each other, unless hit by a projectile, at which point they will deal contact damage to their attacker.

## Trivia

* This is a reference to Judas betraying Jesus after the Last Supper, leading to Jesus' death by crucifixion.
* Betrayal's updated behavior bears a similarity to the monster infighting mechanic from the *Doom* series, *Heretic*, and *Hexen*, which similarly causes enemies struck by another enemy's attack to prioritize attacking that monster over the player character.
