Evil Charm

**Evil Charm** is a passive item added in *The Binding of Isaac: Repentance*.

## Effects

* Gives Isaac +2.0 luck.
* Makes Isaac immune to burn, confusion, fear, and toxic gas clouds.
	+ This also includes the  aura from Dogma's projectiles.

## Notes

* Poison clouds from destroying mushrooms still affect Isaac. Only lingering toxic gas clouds are rendered harmless.

## Trivia

* Evil Charm is from the *Antibirth* mod. In *Antibirth*, it would grant a higher +3 Luck but with no other benefits.
* Only poison and fear are actually used by enemies in the game, but the others are also defined and guarded against by the Charm.
* The Evil Charm looks very similar to a real life item called a Nazar, which is said to ward off the curse of the Evil Eye.
* This item was supposed to have its own unlock method which was later cut from the game. The achievement popup graphic can still be found in the game's files.
Dog Tooth

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

## Effects

* +0.3 damage.
* +0.1 speed.
	+ Also affects maximum speed (may never exceed 2.0).
* When entering a room connected to an undiscovered Secret Room or Super Secret Room, a howl sound effect will play.
* A barking sound will play if there is an undiscovered Crawl Space in the room.

## Notes

* A sound won't play in the first room of a new floor until you re-enter the room.
* An extra Crawl Space added by  will not trigger the sound.

## Sounds

Plays when an undiscovered Crawl Space is in the current room.

Plays when an undiscovered (Super) Secret Room is adjacent to the current room.

## Trivia

* The pickup quote appears to refer to the way the game associates Moon with secrets, with  teleporting to secret rooms and  being a torn Moon card that spawns extra secret rooms.
* "Bark at the moon!" could also be a reference to the song and album made by Ozzy Osbourne.
Dead Sea Scrolls

**Dead Sea Scrolls** is an activated item.

## Effect

When used, a random activated item effect will be activated from the following:

## Notes

* When Bob's Rotten Head or Shoop Da Whoop! is chosen, Dead Sea Scrolls will not lose its charge until said item is thrown or released.
	+ This allows Isaac to press Spacebar again if need be to skip over said items in the rotation while keeping full charge, allowing it to be used again for a different effect.
		- This doesn't work if Bethany has Soul Charges and Book of Virtues.
* It may be helpful to use Dead Sea Scrolls upon entering an enemy room, as many of its effects such as The Gamekid and Tammy's Head are helpful in combat.
* As many of Dead Sea Scrolls effects involve explosions, using it near Tinted Rocks or potential Secret Room entrances can potentially be helpful when low on bombs.
	+ While  and  can hurt the player, effects such as , , ,  and  will pay out with more health than is lost long-term.

## Synergies

* : Each wisp spawned has the attributes of the active item that was triggered.

## Interactions

* : Two effects are activated, with only one being named on screen.

## Gallery

* 3DS The icon of Dead Sea Scrolls as seen on the lower 3DS screen.
* Dead Sea Scrolls' splash image which appears when it's activated.

## Trivia

* The Dead Sea Scrolls are a collection of 981 Hellenistic-period manuscripts found within caves on the north shore of the Dead Sea.
	+ The pickup quote "It's a mystery" references the item's effect, as well as the fact that the real Dead Sea Scrolls are so tattered and eroded that reading them can prove impossible.
Friend Zone

**Friend Zone** is a passive item added in *The Binding of Isaac: Afterbirth*.

## Effects

* Spawns a white fly familiar that slowly orbits Isaac and deals 3 damage per tick or 45 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

* This familiar orbits Isaac at a middle-length distance somewhere between  and .

## Trivia

* A reference to the "friend zone", a phenomenon where one person in a platonic relationship has romantic feelings for the other person and the other one does not, seeing them as "just a friend".
* Friend Zone is very similar in appearance to  and , making them difficult to distinguish.
* Friend Zone is a recolored .
Devil's Crown

**Devil's Crown** is an unlockable trinket added in *The Binding of Isaac: Repentance*.

## Effects

* Every Treasure Room is replaced with a **Devil Treasure Room** that contain items from the Devil Room item pool that can be bought for the usual number of Heart Containers normally requested (for the spawned item) in a Devil Room.

## Notes

* The **Devil Treasure Room** generated will be the same as the Treasure Room that would have been generated, minus the item and room textures.
	+ Multiple choice Treasure Rooms, such as those generated in alternative floors and ???, allow both items to be taken upon being converted to Devil Treasure Rooms. The blind item on alternate floors will still be blind, however.
	+ Urns, mushrooms, polyps, and buckets will be converted into skulls.
* This trinket also converts Treasure rooms on the current floor when picked up. However, this only affects Treasure Rooms that have not been visited yet.
	+ The same goes vice-versa: dropping the trinket will convert Devil Treasure Rooms to normal ones unless they've been visited.
* Items bought in the Devil Treasure Rooms will affect Angel Room chance like a normal Deal with the Devil would.
* When entering floors during the Ascent, Treasure Rooms that you visited during the run will keep their previous state, and will be unaffected by this trinket.
	+ However, unvisited Treasure Rooms can still be converted by dropping and picking up the trinket.
	+ if playing as  Keeper or  Tainted Keeper item's prices will be 99 cents during the ascent
* Does not affect the Silver Treasure Rooms in Greed Mode.
* Extra treasure rooms generated by  will be affected normally.
* Items spawned in Devil Treasure Rooms (e.g via , , , etc.) will all be drawn from the Devil Room item pool.
* Devil's Crown does not affect the reversed Treasure Room in Downpour/Dross II.

## Synergies

* : All **Devil Treasure Room**s will have two items, both of which can be purchased.
	+ This also extends to ,  and  cards buffed by .

* : When used in a **Devil Treasure Room**, gives the item for free, acting like a regular Treasure Room but with devil items, only requiring the use of Coupon.
	+ This doesnt affect the Angel Room chance, like how using  in a regular Devil Room and grabbing the free item wouldn't.

* : Shows you the item that spawns without the trinket, allowing you to drop the trinket before entering if you think the treasure room item would be better than the devil deal.

* : Allows you to check the item that spawns with and without the trinket, letting you pick the better item.

## Interactions

* : Devil Treasure Rooms will count as regular Devil Rooms for the purposes of this item.

## Trivia

* Devil's Crown originates from the *Antibirth* mod.

Dople

### Found In

**Doples** mirror Isaac's movements exactly. They attack by firing projectiles but only when Isaac fires tears, and these shots are fired at the same frequency as Isaac's tears.

## Variations

### Stage HP

 20
 0

### Found In

 Rare chance to replace **Doples**

**Evil Twins** shoot three spread blood shots instead of one but have a reduced fire rate. Also, due to the fact that they have flight, they cannot be hurt by spikes.

### Notes

* They can spawn in unique Devil Room layouts if Isaac is holding the .

## Notes

* Doples often appear in rooms that have hazards, such as Spikes. It is possible to kill a Dople by maneuvering Isaac in such a way that the Dople walks onto a hazard, though these spots are often blocked by obstacles such as rocks, key blocks, or Hosts.
* Doples and Evil Twins do not deal contact damage, allowing Isaac to utilize contact items like  against them without risk.
* If Isaac attacks with an item that replaces regular tears with a charged attack such as , Doples and Evil Twins will only attack when the beam first starts to charge up.
* If Isaac is blindfolded, Doples and Evil Twins will not attack.
* If Isaac has low tear delay, the Dople (but not the Evil Twin) will fire very rapidly at the same rate as Isaac, making it very dangerous.
* The Dople, despite mirroring Isaac's movements exactly, do not mimic his range. As a result, they can be significantly easier if Isaac has a higher range and attacks from as much of a distance as possible.
* If you are to charm a Dople/Evil Twin in a room with other enemies, the Dople/Evil Twin will try to copy the movement of every other enemy in the room, resulting in teleportation all around the room at very high speeds.
* When playing with multiple characters, such as  Jacob and Esau or when using , Doples/Evil Twins will mimic only one of them. Multiple Doples/Evil Twins will mimic different characters.
	+ If a temporary character dies, their Dople/Evil Twin will also die.

## Trivia

* Evil Twins appear to have  ability, given the fact that it has a spread of 3 shots and a slower fire rate compared to Doples.
* Doples and Evil Twins are based on the term doppelganger, which means a double of a living person.
* Doples are a reference to Doppelgängers from the game Tomb Raider. It's a replica of Lara Croft, the protagonist of the video game, and can be found in The Great Pyramid. It's a skinless creature that would mirror the player's movements and could be tricked into jumping into a pit of molten lava.
Doctor's Remote

**Doctor's Remote** is an activated item.

## Effect

* Upon activation, a large red crosshair will appear on the ground. The crosshair can be moved using tear controls.
* After approximately 2 seconds, a large missile will land on the red marker. The missile acts like a large bomb explosion, dealing 20 times Isaac's damage (the same as ).

## Notes

* This item shares many of the synergies and interactions with Epic Fetus.
* The red marker works different from Epic Fetus' marker when controlled with the mouse: While pressing mouse left button, it keeps going away from Isaac, not following the mouse.
* Activating the item again while the crosshair is on the ground will cancel the animation of Isaac holding up the remote and allow him to shoot tears sooner.
	+ Activating the item again while having full charge (e.g. with ) will also deplete the charge, wasting it.
	+ Taking damage also cancels the animation.
	+ The missile will still drop on the crosshair, which can no longer be controlled.
	+ This will cancel the missile drop and remove the crosshair.

## Synergies

* : Spawns grey bomb-like wisps in the middle ring. When Doctor's Remote is used, the wisps fire two inaccurate, explosive tears at the crosshair in an arc that deal 14 damage (28 with ).

## Interactions

* : No effect.
* Tainted Azazel: Shoots thin  beams when rocket explodes. This behavior is not shared with , which produces no brimstone lasers.

## Trivia

* This is a reference to an item used by the antagonist in Super Meat Boy, "Dr. Fetus".
* Epic Fetus is the endless version of this Item and, as such, uses the same attack animation.
* The sprite of this item is identical to  and , but with a different color.
* In the original *The Binding of Isaac*, this item was used in the challenge "The Doctor's Revenge".

## Gallery

* 3DS The icon of Doctor's Remote as seen on the lower 3DS screen.
Flooded Caves

*(chapter 2)*

The **Flooded Caves** is one of the environments in chapter 2 added in *The Binding of Isaac: Afterbirth*. The theme of the Flooded Caves is water; as such, most of the enemies inhabiting it are airborne, such as One Tooth and flies, and many of them shoot projectiles, while there are fewer ground-bound and contact-damage-reliant enemies. Rocks have a chance to be replaced with water-filled pits and some enemies like the Hive have a chance to be replaced with their drowned variants.

The Flooded Cave's alternate floors are the Caves and the Catacombs.

After  A Secret Exit is unlocked, a boarded door similar to the one leading to a Bedroom will appear in this floor's Boss Room upon defeating the boss, leading to the Mines / Ashpit. This door, like a Bedroom, requires two bombs to be opened. Unlike Angel Rooms and Devil Rooms, this door never disappears.

 Though there is some overlap with Downpour due to both featuring water flooding, Downpour's unique enemies are often ghostly and supernatural in nature as opposed to the Flooded Cave's theme of drowned or bloated enemies.

 The Flooded Caves are unlocked by defeating It Lives 16 times.

## Effects

* When at exactly 1 Red Heart, some of Isaac's stats are increased.
	+ +0.75 tears.
	+ +2.0 fire rate. The bonus can break the soft tears cap.
	+ +1.5 range.
	+ +1 tear falling speed.
	+ +0.2 shot speed.
* The effect is lost any time Isaac gains or loses Red Hearts.
	+ The crown will glow red while active; if inactive, it will appear black.

## Notes

* Full Bone Heart containers are counted towards the maximum.
* This item pairs well with  Eve, since she starts with , and is the only character that can gain Whore of Babylon's effect at 1 heart.
* This item does not affect  ???,  The Lost,  The Soul,  Dark Judas,  Tainted Judas,  Tainted ???,  Tainted Lost,  Tainted Soul, or  Tainted Bethany since they cannot gain Red Hearts.
* This item only affects  Keeper and  Tainted Keeper when he has only one Coin Heart.
* This item only affects  The Forgotten when he has one full Bone Heart.
* The effect does not stack with multiple Dark Prince's Crowns.

## Trivia

* This is the demonic counterpart of the .
* Prior to *Repentance*, the item's name was *Dark Princes Crown*, without an apostrophe.
Deep Pockets

### Collection Grid

*(page 4, column 11, row 3)**(page 4, column 11, row 3)**(page 4, column 12, row 3)*

### Unlock Method

 Defeat ??? as  Keeper

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

## Effect

* Allows Isaac to carry two cards or pills (or a combination of both) at the same time.
* Increases the coin cap to 999.
* If a room would otherwise yield no reward, 1-3 random coins will spawn.
	+ All coins spawned will be of the same type.

## Notes

* This item has the same effects as  and , but without removing pills/cards from the game.
* This item has the same effect as .
* Has no effect on spawning coins in Greed mode, including the trapdoor/exit room.
* Losing this item while holding more than 99 coins will reduce coin count to 99. Picking it back up again (if playing as Tainted Isaac, for example) will not restore lost coins.

## Synergies

* : Allows Isaac to gain the full 100 coins when picking this up.
* : After exceeding 100 coins, Isaac gains an extra Heart Container for every 100 coins instead of every 25.
	+ Keeper/ Tainted Keeper: The limit of 12 heart containers can be bypassed, allowing for up to 15 coin hearts at 999 coins. Additional coin hearts past 12 are not displayed.
* : Increases maximum damage bonus. The damage caps at +39.96 damage with 999 coins.
* : Increases maximum contact damage. The damage caps at 203.3 damage with 999 coins.
* : A pickup, card, pill, trinket, or Chest will accompany each coin.

## Interactions

* : No effect, only two pills or cards can be held.
	+ No effect. Only 999 coins can be held.
* : Possibly detrimental. Since room clear rewards become very common at high luck, the 1-3 coin drop will rarely occur.

## Trivia

* Prior to *Repentance*, this item's description was "More stuff to carry!"
Dataminer

**Dataminer** is an activated item added in *The Binding of Isaac: Afterbirth †*.

## Effects

* For the current room, rotates every enemy and pickup 90 degrees and moves its sprite up and left.
	+ Enemy hitboxes remain the same.
* Increases one of Isaac's stats and decreases another. Possible stat changes include:
	+ ± 1 flat damage
	+ ±0.5 tears
	+ ±0.5 fire rate
	+ ±0.2 speed
		- Also affects maximum speed (may never exceed 2.0)
	+ ±0.2 shot speed
	+ ±1 luck
	+ ±0.5 range
	+ ±2.5 range
* Adds random tear effects for the current room.
* Distorts the music for the current room.

## Synergies

* : Spawns a special wisp on the middle ring that is otherwise undistinguishable from a normal wisp. These wisps' tears have a 5% chance of transforming any non-boss enemy into random wisps.
* : The stats are locked to the highest number achieved, though if a stat that got lowered is increased by Dataminer, you won't actually have an increase, making it increasingly hard to get a higher peak of stats.

## Notes

* If the tears stat reaches a negative number, there will be a wrap-around into the maximum fire rate of 120; if the tears stat is boosted back into a positive number, fire rate will again become low.
	+ If Rock Bottom is obtained while the tears stat is negative, fire rate will stay at 120 even if boosts are obtained.
* The minimum values for each stat are as follows:
	+ Damage: 0.5
	+ Speed: 0.1
	+ Shot Speed: 0.6
	+ Range: 1.0
* Further changes to Isaac's stats are still calculated normally behind the scenes, but their *effective* values cannot go below the minimum. For example, 0.5 Shot Speed will *behave* as though it were 0.6, but a 0.2 Shot Speed increase would apply to the true stat value of 0.5, meaning the new stat value would be 0.7.
* Using Dataminer during the fight against The Beast is **not recommended**, as it will distort the stalagmites and stalactites, causing them to be incredibly difficult to dodge.

## Trivia

* The item name and description are a likely reference to the dataminers who discovered the secret of  The Lost, as well as the  Keeper ARG's recurring usage of the number 109.
	+ The item and its pickaxe icon are a play on words on the term data mining, used in the context of gaming communities as extracting data from the game files.
* The item's sprite is a recolor and flipped version of the .
* If used during the Mom fight, a normally hidden part of the leg sprite, revealing a blue skirt with yellow polka dots, will be visible.
* If Dataminer is used right before traveling to the next floor, the music for the transition screen will be affected by it.
	+ Also affects the music during the Game Over screen (Isaac's last will), if activated before death.
* In a Q&A from Twitter, Edmund McMillen considered Dataminer to be the worst item in *The Binding of Isaac*.
Dice Shard

"D6 + D20"

**Dice Shard** is a consumable item added in *The Binding of Isaac: Afterbirth*.

## Effects

Upon use, it:

* rerolls all pedestal items in the room (like )
* rerolls all pickups in the room (like the )

## Notes

* Like runes, and despite having a different appearance, this item is counted as a card. Therefore, it will work with  as an effective combo.
	+ This item cannot be mimicked by either  or , and  has no effect on it.
* Dice Shard's ID was changed from 44 to 49.

## Trivia

* The item's appearance is similar to , but broken in half.
* Dice Shard is similar to  in that they are both one-use broken versions of an active item. However, Dice Shard has an additional effect that The D6 lacks while Cracked Key simply replicates the use of Red Key.
* Despite being a dice item, Dice Shard is not an unlock.
	+ This trait is shared with  and .
Experimental Treatment

**Experimental Treatment** is an unlockable passive item.

## Effects

* Randomly increases at least 1 and decreases 1-3 of Isaac's stats. The same stats can be increased/decreased multiple times.
* Randomly increases 4 and decreases 2 of Isaac's stats.
* Each increase or decrease for a stat will change it by a fixed value:
	+ ±1 health.
	+ ±1 flat damage.
	+ ±0.5 tears.
	+ ±0.5 fire rate.
	+ ±0.5 range.
	+ ±2.5 range.
	+ ±0.2 shot speed.
	+ ±0.2 speed.
		- Also affects maximum speed (may never exceed 2.0).
	+ ±1 luck.
* If a stat that is already at an upper or lower limit is chosen, there is no visible effect.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a buff berserker.

## Notes

The stat changes are permanent and will not go away if the item is removed.

* This makes the item especially useful for  Tainted Isaac, since he gets to keep the stats while having the option to switch Experimental Treatment for another item and the transformation progress isn't lost in the process.

 The tears up from this item is allowed to go past the normal tear cap of 5.0. However if it decreases tears, the normal tear cap will also be decreased.

## Unlockable Achievements

* Little Baggy - Pick up any 2 of the following items in a single run: , , , , and  ( Any 2 items that have the 'syringe' item tag).

## Trivia

 Prior to *Repentance*, this item's description was "All stats up... then shuffled".

* Despite the item's old description, the item did not increase all stats or shuffle them.

## Gallery

* Experimental Treatment in ending 7.
* Isaac using Experimental Treatment in ending 7.
Dirt Patches

* Dirt Patches are small mounds of dirt found only in Grave Rooms that can be dug into with certain items.
* Using  on top of a Dirt Patch will reveal a skeleton and unlock  The Forgotten.
* Prior to unlocking The Forgotten, the Grave Room containing the Dirt Patch only has one layout with one Dirt Patch in the middle.
* Using Mom's Shovel (After unlocking The Forgotten), , or  on top of a Dirt Patch will dig up a random chest.

## Unlockable Achievements

* The Forgotten - It's complicated.

* Bone Heart - It's complicated.
Empty Heart

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

## Effects

* If Isaac has one red heart or less at the beginning of a floor, an empty heart container is added.

## Notes

* As there is no special exception, this item will have no effect for characters that cannot have red hearts :  Dark Judas,  ???,  The Lost,  Keeper,  The Forgotten,  The Soul,  Tainted Judas,  Tainted ???,  Tainted Lost,  Tainted Keeper,  Tainted Soul and  Tainted Bethany.
* The empty heart containers will replace any other heart containers if the maximum has been reached.

## Synergies

* : Activates the damage up effect of Adrenaline if conditions are met to grant an empty heart container at the beginning of each floor.
* : If no Devil Beggars or Blood Donation Machines can be found, the Crow Heart trinket is a great way to guarantee red hearts are lost so long as you still have non-red health available.
* : The heart containers are empty when granted, which allows the crown's buff to stay active when advancing floors.
* : The heart containers granted by Empty Heart can be used by Guppy's Paw while staying at or below 1 red heart, granting massively increased survivability.
* Lazarus: The heart containers granted by Empty Heart allows Lazarus to effectively negate the downside that removes a single heart container on death, allowing him to purposefully use his mechanic to get a +0.5 damage up per floor. (As long as he still proceeds at one red heart or less)
* : The heart containers granted by Empty Heart can be used by Potato Peeler while staying at or below 1 red heart, granting increased damage and a  per floor.
Door Stop

**Door Stop** is an unlockable trinket added in *The Binding of Isaac: Afterbirth † (Booster Pack #3)*.

## Effects

* While held, the last door Isaac went through stays open, allowing him to leave the room even if enemies are in it.
	+ Does not prevent doors from closing due to other triggers, e.g. a Challenge Room door will still close upon opening a chest.

## Notes

* Does not work on Secret Room openings.
* Does not work in Greed Mode.
	+ Cannot spawn in Greed Mode.
* This allows Isaac to leave rooms, including boss rooms, if the fight goes poorly.
	+ This becomes particularly useful in The Void, where there are multiple boss rooms; Door stop lets the player peek behind each boss room, and thus able to decide whether to face Delirium or other bosses first.
* Leaving immediately after enemies have spawned gives the player information on the fight, potentially improving decision making.
* If a Devil Room has a Krampus fight in it, Isaac may choose not to fight him and leave.
* If an Angel fight is started in an Angel Room the door will close and prevent leaving despite the Door Stop.
* If Greed spawns in a Secret Room or Shop, Door Stop can be used to leave and come back to fight Greed again to potentially get more than one .
* Does not affect Mom's boss room.
* Can be used to reset  shield. Very useful playing as  The Lost.
* If a room contained champion enemies, upon leaving and re-entering the room, all previous champion enemies will have turned to regular enemies.
* Cannot be used to escape Boss Rush after the fight has started.
* Cannot be used to escape the Mega Satan fight.

## Synergies

* / : Provides infinite charges by clearing some enemies then leaving the room, and repeating.
* / : Allows the possibility to generate unlimited Hearts.
* : With enough patience, Coins can be gathered infinitely.
* Tainted Keeper: Leaving and re-entering the room allows for limited coin farming; however, enemies in rooms Tainted Keeper has already visited will eventually stop dropping coins.

## Gallery

* Door Stop's appearance in the original Steam Workshop mod.
* Door Stop's original appearance prior to Booster Pack #4.

## Trivia

* Door Stop is based on this Steam Workshop trinket by Strawrat and CupertinoEffect - which in turn is based on this Steam Workshop trinket by Lord Pigfoot Nosebeggar XVII.
* The pickup quote may be a reference to the *Game of Thrones* episode The Door where the same quote is repeatedly exclaimed.
Dark Bum

### Collection Grid

*(page 3, column 3, row 8)**(page 3, column 13, row 2)**(page 3, column 14, row 2)*

**Dark Bum** is a passive item.

## Effects

* Spawns a familiar that follows Isaac around and collects Red Hearts. For every one-and-a-half Red Hearts collected, Dark Bum will generate one of the following:
	+ A single Soul Heart.
	+ A single Black Heart.
	+ A hostile Spider.
	+ A friendly Blue Spider.
	+ A random pill, card, or rune.

 Loot Table
 Spider | 10%

* This item belongs to the  set. Collecting three items from this set will transform Isaac's bums into Super Bum.

## Notes

* If Dark Bum enters one of a set of Super Secret Rooms which allow only certain types of Hearts to generate in them, he will drop that type of heart instead of what he normally would.
	+ The one which only allows Red Hearts will cause Dark Bum to consume the Red Hearts on the floor only to generate yet more Red Hearts. Leading Dark Bum around the room to consume the Red Hearts and then leaving the room before he's able to generate anything will avoid this.
* Dark Bum will not pick up Gold Hearts,  Blended Hearts,  Bone Hearts, or  Rotten Hearts.
* Very beneficial for characters that can't have heart containers ( ???,  Tainted ???,  Dark Judas,  Tainted Judas,  Tainted Forgotten) since they have no use for Red Hearts.
	+ Alternatively,  The Forgotten or characters with low health may suffer from Dark Bum, as it will make it harder for The Forgotten to maintain Bone Hearts.
* Scared Hearts will run away from Dark Bum. Try to pinch them between Dark Bum and Isaac so he can collect them.
* From a scoring perspective, Hearts that Dark Bum picks up count towards your Schwag bonus on daily runs.
* Dark Bum does not join the line of familiars that follow behind Isaac.

## Synergies

* : Each Half Red Heart dropped by Little C.H.A.D. can be collected by Dark Bum, increasing the amount of pickups dropped.
* : Enemy kills have the chance to drop Half Red Hearts that can be collected by Dark Bum, which when combined with Gimpy's chance to drop Soul Hearts when Isaac is damaged is a good way to generate Black Hearts as well as other pickups.
* : Most Red Heart drops will become Double Red Heart drops. This counts as two full Red Hearts for Dark Bum, essentially doubling the value of it.

## Trivia

* This item is the Devil Beggar counterpart of  and .

## History

* v1.02: Dark Bum's Red to Soul Heart conversion rate was set to 1.5:1.
* v1.031: Dark Bum was changed to have a chance to spawn friendly Blue Spiders or hostile Spiders.
* v1.06.J796: Dark Bum can no longer be found by  Tainted Lost.

Demo Man

**Demo Man** is challenge #9. Isaac starts off with , , and the  trinket. The goal is to defeat Mom's Heart or It Lives. This challenge is available after unlocking Dr. Fetus.

## Difficulty

The only weapons are Bombs, which can harm Isaac if he's too close. The  works on the Dr. Fetus bombs that replace tears but does not prevent them from exploding after their fuse runs out.

 causes more bomb drops than other drops, such as Hearts or Chests. Since there is an unlimited supply of bombs, this can be a hindrance.

## Strategy

* Since every run starts with Dr. Fetus, there is a virtually infinite supply of bombs. Anything that would normally use bombs can be done by attacking.
* While Remote Detonator does not prevent bombs from detonating, using it will still cause them to explode prematurely.
* Shot speed will cause the bombs to launch faster and farther.
* Flying can help with avoiding explosive damage in tight quarters. This can make  or  more valuable.
* The infinite bombs allows testing every wall for Secret Rooms and Super Secret Rooms. They also enable Isaac to escape rooms without clearing them by blowing open the doors.
* Acquiring explosion immunity via items such as ,  or  make this challenge significantly easier. Ipecac immunizes Isaac only to the bombs fired by Dr. Fetus, however, not their possible fragments or other explosions.
* If one manages to acquire , this challenge will be made easier, as the rockets travel linearly and explode on contact, making self-damage less likely.

### Placed Bombs

* causes more bomb drops than other drops. Since regular bombs are more powerful than the Dr. Fetus bombs, this can be a boon. Dr. Fetus bombs can blast obstacles and walls, allowing placed bombs to be saved for combat.
* Combined with the , more control can be had over placed bombs and can lay traps with them. This is especially useful during boss fights with invincibility periods, such as Mom's Heart and Pin, as multiple placed bombs can be laid near the boss's spawning point and detonated all at once.
* If a placed bomb is misplaced, they can be moved by walking into them. Placed bombs will not explode until Remote Detonator is used, so Isaacs can move out of the way of explosive damage.
* It is possible to drop the Match Stick by using Ctrl(PC), R2(PS4), or ZR(3DS, Switch).

## Reward

* Chaos Card - Complete **Demo Man (challenge #9)**.

## Trivia

* This challenge is a reference to *Team Fortress 2'*s 4th class, the Demoman. The Demoman uses various bombs as his choice of weapons, similarly to how this challenge is played.

## Gallery

Fissure

### Found In

The Fissure is a monster exclusive to Downpour, resembling a fish wearing a skull on its head. Fissures do not need to be defeated to clear the room, and rather act as a stage hazard, spawning endlessly by jumping out of pits and bouncing off walls until they land in a pit again. They can be damaged normally, despite their vague resemblance to Hosts. If a fissure goes too long without re-entering a pit it dies.

## Trivia

* Fissure shares its name with a cut enemy in Repentance, Fissure, which appeared in Antibirth.
Duality

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

## Effects

* Whenever a Devil Room/Angel Room spawns after defeating a boss, the other will also spawn.

	+ Both rooms will spawn even if a devil deal was made before.
	+ In rooms without enough accessible walls, only one of the two will spawn.

## Notes

* Teleportation via a  card, a Red Chest or a Sacrifice Room *before* defeating the boss and choosing a door will follow the normal rules of Devil/Angel Room generation, instead of a 50/50 chance.
	+ This means that if Duality was taken as a Devil deal, or any other deal with the Devil was made in the run, teleportation will always lead to the Devil Room.
	+ The room that was chosen this way will be the only one that opens once the boss is defeated.
	+ Teleporting after choosing a door will always take you to the same room.
	+ Gaining Duality during Greed/Greedier Mode will only generate one room as per normal, rendering it normally useless. Both rooms however will generate in the penultimate floor, The Shop.

* /  Guarantees an Angel & Devil room to spawn after every boss
* : Time can be reversed while inside one deal to go into another.

## Interactions

* Tainted Lazarus: The Lazarus that fights the boss must be the one holding Duality in order for it to trigger.

## Trivia

* Duality is one of only five items to appear in both the Angel and Devil item pools, the others being , ,  and .
* The Duality image appears to be similar in concept to the yin and yang symbol of Ancient Chinese philosophy, as the latter represents the concept of dualism as well. However, they don't quite appear to be exact in terms of the diameter format.

		- Its first charge will always leave room below it to allow for the lower second and third charges.
	+ The horse continues to charge even after Death has been defeated.
	+ It deals heavy damage to any enemy it runs into, except Death.
