Eve's Bird Foot

**Eve's Bird Foot** is an unlockable trinket.

## Effects

* Chance to spawn up to 1  familiar for the current room each time an enemy dies.
	+ The Dead Bird deals 4 damage per second.
	+ The chance increases with luck, starting at 5% at 0 luck and reaching 100% at 8 luck.
	+ The familiar spawns already activated, with no taking damage required unlike the item.

## Notes

* This trinket alone cannot spawn more than one Dead Bird per room. It can, however, stack with  to spawn two in one room.
* The bird familiar spawned by this trinket is transparent and has one missing leg compared to the one spawned by the actual item.
* The familiar will not be cloned by .
* The familiar spawned can be sacrificed with , destroying the trinket in the process.

## Interaction

* Ace Cards: Enemies that are turned into pickups can’t spawn the bird familiar.
* /: Enemies that are turned into poop can’t spawn the bird familiar.
* Freeze Effects: Enemies that die from being frozen can’t spawn the bird familiar.
Flip

**Flip** is an unlockable activated item added in *The Binding of Isaac: Repentance*. It is the starting item for  Tainted Lazarus.

## Effects

* While holding Flip, when Isaac enters a new room containing an item (Treasure Room, Shop, etc.), the item pedestal will have a second "ghostly" item behind it.
	+ The real item can be interacted with normally, while the ghostly item cannot.
	+ The ghostly item will vanish if there is no real item on the pedestal and Isaac leaves the room.
* Upon use, flips all real / ghostly items around on pedestals, allowing Isaac to collect the ghostly items. Does not affect pedestals that do not contain a ghostly item.
	+ As long as the room isn't exited, empty pedestals can be flipped, meaning both the original item and the flipped ghostly item can be collected.
* If playing as  Tainted Lazarus, activating it also flips between them and  Dead Tainted Lazarus.

## Notes

* Flip has no effect on item pedestals that do not generate upon the creation of the room (i.e. Boss items, items from chests / beggars, etc.).
* Buying a real item, such as from a Shop or Devil Room, will also buy the ghostly version for free, although it can still only be obtained using Flip.

## Synergies

* : Spawns a small white Isaac head wisp in the middle ring with high health. If you are playing Tainted Lazarus, the wisp is given to the form that isn't holding Book of Virtues. A wisp is also granted when Flip is automatically used by clearing the room as Tainted Lazarus.
* /  / , etc.: Only rerolls visible item. Ghostly items remain unchanged.
* Tainted Isaac / : The cycling effect only gets applied to the primary item; the ghostly item does not cycle. Using Flip on a cycling item pedestal will cause the currently visible item to switch places with the ghostly one, after which neither item will cycle.

## Interactions

* : No effect.
* : Additional pedestals will not have ghostly items.
* : Ghostly items no longer appear when absorbed by Void, rendering Flip useless.

## Gallery

* Flip item's icon when  Dead Tainted Lazarus is present.

## Trivia

* Flip's icons are the alchemy symbols for death and life, respectively.
* Prior to patch V1.7.6, Flip's pickup quote was "Life and death".
* Prior to patch V1.7.6, using Flip as a character other than Tainted Lazarus after having previously used  would switch between Esau Jr. and the base character. This was most likely a bug, as Flip was not yet obtainable for other characters besides using  or as a starting item for  Eden.
Flat File

**Flat File** is a trinket added in *The Binding of Isaac: Repentance*.

## Effects

* Makes all spikes retract, preventing them from dealing damage.
	+ Most spikes leave behind holes or a visual cue showing where they would normally be.
	+ The spikes around Curse Room doors are removed, allowing them to be entered and exited without taking damage.
	+ Retracts damaging spikes from Spiked Rocks and Spiked Chests/ Mimic Chests.
	+ Removes the spikes from Pokies, Slides, and Wall Huggers.
		- Pokies, Slides, and Wall Huggers don't immediately stop moving once they are despiked, and are still able to push Isaac without dealing damage.
		- Has no effect on Grudges, neither retracting their spikes nor despawning them.
	+ Causes Spikeballs to despawn.
		- Doesn't despawn or retract the spikes on Ball and Chains.
		- Doesn't cause the moveable spike balls in Singe's boss room to despawn or despike.

## Notes

* If Flat File is dropped in a room with spikes, the spikes will not extend again unless the room is left and re-entered.
	+ Spiked Rocks will not re-extend their spikes.
* Mimic Chests won't change their contents when Isaac is up close to them (visible with ) if opened under the effect of Flat File.
* Flat File also retracts the spikes in the center of Sacrifice Rooms, making them unusable while the trinket is held. The spikes reappear after dropping the trinket and re-entering the room.
	+ If Flat File is gulped, Isaac cannot use Sacrifice rooms for the rest of the run.
* Flat File does not prevent The Pile or Mama Gurdy from using their spike attacks.
* Also removes spikes from doors in the Cursed! challenge, making it significantly easier.

## Interactions

* : Doesn't retract spikes placed around consumables in shops.
* : Retracts the spikes, making the item useless.

## Trivia

* The Flat File assumedly "files" down the spikes, like one would file the jagged imperfections from their nails, or file metal bars to escape from jail.
Fun Guy

After obtaining three mushroom items from the following list ( 3 items with the `mushroom` item tag), Isaac turns into a walking Mushroom and grants a Red Heart Container.

## Trivia

* The name Fun Guy is a slang term for psychedelic Psilocybin mushrooms and a wordplay on "fungi".
* Fun Guy's appearance may be a reference to the character *Toad*, a humanoid mushroom from the *Super Mario* franchise.
Depression

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

## Effects

* Spawns a familiar that follows Isaac and leaves a trail of blue creep that damages enemies.
	+ The creep deals 2 damage per tick or 6 damage per second to non-flying enemies.
* If the cloud touches an enemy, it has a small chance to spawn a damaging  beam onto the enemy.
	+ The light beams deal 20 + Isaac's tear damage per tick and may strike an enemy up to 8 times.

## Notes

* Familiars that follow behind Isaac have a certain priority in how close their position is to him over other familiars, with Depression having the lowest priority at 6th and thus being farther from Isaac than familiars of different priorities.

## Interactions

* : Increase cloud size but does not increase damage.

## Trivia

* Depression is the emotional state of low mood and aversion to activity.
* Depression is also a state of air currents which often result in cloudy and wet weather.

## Gallery

* Item concept arts for AB+, including Depression.
Eve's Mascara

### Collection Grid

*(page 4, column 5, row 1)**(page 3, column 5, row 4)**(page 3, column 6, row 4)*

### Unlock Method

 Complete the Boss Rush as  Eve

**Eve's Mascara** is an unlockable passive item.

## Effects

* 2x damage multiplier.
* -0.5 shot speed.
* 0.5x tears / 2x tear delay multiplier. (The player's tear value will always be halved.)
* 0.66x tears / 1.5x tear delay multiplier.

## Notes

* Eve's Mascara is DPS neutral, though often the reduction of shot speed is a downgrade.
* Combos very well with any item that scales with damage but not with fire rate, such as  or .
* Eve's Mascara is effectively a 33% increase in DPS, and the shot speed down is no longer as detrimental due to changes in how range works.

## Synergies

* : When Eve's Mascara is picked up instead of being converted into a locust, it grants all of Abyss's locusts the high damage up without suffering the tears down allowing Isaac to increase his damage rate substantially the more items he uses Abyss on.
* : Missiles are not affected by low shot speed and the fire rate difference is negligible, granting double damage with nearly no downside.
* : The Knife is not affected by shot speed. Tears down and 2x damage multiplier still apply.
* : Beams turn black and do double damage. The low shot speed makes beams damage enemies more frequently.
* : Tech X benefits from a lower shot speed due to it staying on enemies longer and is also not affected by range, giving little downsides.
	+ The tears down can be a major downside as it takes longer to charge Tech X and the damage dealt by Tech X is less than Isaac's damage when it is not fully charged.

## Interactions

* : The damage and tear multipliers do not stack. The shot speed decrease does stack.
* / : Shots travel a very short distance, so having  or  is strongly recommended.
* : No further effect when stacked.
* : **Not recommended.** Tear travels very slowly, making it hard to kill mobile enemies.
Extension Cord

*Not to be confused with .*

**Extension Cord** is an unlockable trinket added in *The Binding of Isaac: Afterbirth † (Booster Pack #4)*.

## Effects

* Bolts of electricity arc between Isaac and his familiars, damaging any enemies between them.
	+ The bolts do 6 points of damage per strike.
	+ The bolts flow through each familiar in reverse order of acquisition, and reach Isaac last.
	+ A bolt arcs every 2 seconds with one familiar. 3 of them arc per second with two familiars. 7.5 per second with three or more familiars.

## Notes

* The Forgotten acts as a familiar while controlling  The Soul, causing electricity to arc between them.  The same applies for  Tainted Forgotten and  Tainted Soul.
* Does not affect temporary familiars or ’s gray flies.
* The bolts will damage destructible obstacles, such as TNT and Fire Places, as a normal tear would.
* If taken as  Jacob and Esau, electricity will arc to familiars held by both characters, not just the familiars owned by the character holding it. It will also arc between Jacob and Esau, even if neither have any familiars.
* In co-op mode, electricity will arc to all of them, similar to Jacob and Esau. Their familiars will also be connected.

## Interactions

* **Extension Cord**: Holding two copies or a golden version of this trinket, or having  has no effect.

## Gallery

* Extension Cord's appearance in the original Steam Workshop mod.
* Extension Cord's appearance prior to Booster Pack #5.
* Extension Cord's electricity striking 's last location after it explodes.

## Trivia

* Extension Cord is based on this Steam Workshop mod by Strawrat and CupertinoEffect, which was originally a passive collectible.
Dingle Berry

**Dingle Berry** is an unlockable trinket added in *The Binding of Isaac: Repentance*.

## Effects

* Spawns a random friendly Dip upon clearing a room.
	+ Spawns a random friendly Dip upon starting a new wave in Greed Mode.
* Turns enemy Dips into friendly Dips, similar to .
* Dips come in Poops variants rather than Dip variants. Golden variants drop coins on being damaged and can turn enemies into gold. Red variants do extra damage. Rainbow variants turn into a heart upon death. White variants are harder to kill. Black and Corny variants have had no extra visible effects.

## Synergies

* / Golden Trinket/: Each effect/trinket copy stacks granting 1 extra dip per stack.

## Trivia

* Dingle Berry might be a reference to Dingle, as both are poop themed and Dingle's name is thought to come from the word "dingleberry", which means a small ball of feces clinging to an animal.
Dingle

Double Trouble

(with Mega Maw)

(with another Dingle or Brownie)
Degraded Boss

**Dingle** is a boss that can appear:

* Only in the Basement.
* In the Basement and the Burning Basement.

He is the boss version of the Dips.

## Behavior

Dingle remains stationary and performs the following attacks:

* Fires 3 projectiles towards Isaac.
* Whistles before summoning 1-3 Dips and then fires 3 projectiles at Isaac.
* Quickly performs 3 long dashes towards Isaac while bouncing off obstacles and walls, after which he pauses to catch his breath.
	+ Dips caught in his dashes are knocked back a distance.
	+ Occasionally, Dingle will leave behind a Poop while using this attack.

## Champion Versions

 **Black**: Dingle summons Spiders instead of Dips and fires eight shots in all directions instead of spitting three at Isaac. He also dashes much faster, but will only dash one time instead of three.
 **Red**: Dingle summons Red Poop instead of Dips. He also dashes four times instead of three, though the dashes are shorter and slower.  He also fires blood projectiles instead of poop projectiles, though it is a purely cosmetic effect.
## Gallery

* Dingle in-game.
* Black Champion Dingle.
* Red Champion Dingle.
* Dingle as one of  Delirium's forms.
* Early sketch of Dingle (sketch name presumably "Pooper"), along with Mama Gurdy.
* Concept art of Dingle and its multiple attacks.

## Arena

Dingle can spawn in normal or horizontal tiny rooms.

When fighting Dingle, the following obstacles can spawn:

* Nothing
* 12 rocks (6 in top-left and 6 in bottom-right corners)
* 10 poops (3 per upper corner and 2 per bottom corner) + Fly
* 4 poops (near all corners) + Dip
* 4 Corny Poops (in all corners) + 2 Dart Flies
* A tiny room with a special layout.
	+ Tiny boss rooms have been removed in Repentance.

## Notes

* kills Dingle instantly and causes him to leave behind 6 Dips.
* If a Bomb from  goes off in the same room as Dingle, it will heal him.  This is especially bad if Isaac happens to have , which causes him to drop butt bombs while firing tears.
	+ Butt Bomb effect on  or  does not heal Dingle.
* If Dingle appears as a boss in the Womb (double trouble), both Dingles will always appear as Black Champions and will spawn alongside two Squirts and a Dinga.

## Trivia

* Dangle and Brownie are related to Dingle.
* The name 'Dingle' derives from the crude term, "dingleberry".
* Dingle was the first new boss to be shown by Edmund.[1]
* Dingle is referred to as male by Edmund.[2]
* There are three other poop monsters: Dinga, Squirt, and Dip.
	+ Two more poop monsters ( Corn and Dank Squirt) and three poop bosses (Brownie, Dangle, and the Turdlings) were added.
	+ Four more poop monsters ( Big Corn, Drip, Splurt, and Hardy) and three poop bosses ( Clog, Colostomia, and Turdlet) were added.
* The Black Champion Version of Dingle acts slightly similar to the Dank Squirt and appears to be a "dank" or meconium version of Dingle.
* Prior to *Repentance*, all versions of Dingle could fire blood projectiles instead of just the Red Champion variant.
Eternal D6

**Eternal D6** is an unlockable activated item added in *The Binding of Isaac: Repentance*.

## Effects

* Upon use, replaces every pedestal item in the current room with other random items corresponding to the current room's item pool.
	+ Each pedestal item rerolled has a 25% chance to disappear.

## Notes

* The Lost starts with this item, even if it hasn't been unlocked yet.
* Killing Florian last in an Ultra Pride fight has a chance to drop the Eternal D6 if unlocked.
* In rooms with multiple item pedestals, each pedestal has a separate chance of disappearing when rerolled.
* Luck has no effect on the item.

## Synergies

* : 50% to spawn an eternal white glowing wisp on the middle ring, which cannot be destroyed. Every use has a 50% chance to destroy all the wisps instead of spawning another. Does not affect wisps other than the ones made by this item. Rerolling items does not affect this chance.

## Interactions

* : Re-rolls twice like , but the 25% chance of the item disappearing is increased to approx 44%.

## Trivia

* Eternal D6 originates from the *Antibirth* mod, where it had a charge time of 3, like the Dice in the original *Binding of Isaac*.
* This item functions similarly to the D6 in the Eternal Edition of the original *Binding of Isaac*, where it had a chance to delete the item instead of rerolling it when playing on hard mode.
* This item's collectible sprite refers to it as "Florian's D6".
	+ The secret popup for this item even depicts Florian Himsl lovingly rubbing said D6, indicating he really likes this item. Florian having a chance to drop Eternal D6 in the Ultra Pride fight is also a nod to that.
Danny

### Found In

 This article is about the monster found in Mines. For other uses, see Danny (Disambiguation).
**Dannies** are an enemy added in *The Binding of Isaac: Repentance*. They are exclusive to Mines and Ashpit.

They walk towards Isaac, periodically spitting a burst of rocks towards him, up to two of which may be Rock Spiders. Their rock bursts cannot spawn Rock Spiders if the two it spawned are still alive. Dannies have a long cooldown between rock bursts, but are more likely to use it soon after Isaac enters the room.

## Variants

### Stage HP

 40
 0

### Found In

**Coal Boys** appear in the Mines and Ashpit. They walk towards Isaac, periodically spitting four hot coals towards him, one of which may be a Coal Spider. Hot coals linger and can hurt Isaac, but disappear after ~15 seconds, and disappear faster if they take damage. Coal Boys cannot summon coal spiders if the one it spawned is still alive. Coal Boys have a six second cooldown between coal spits, but are more likely to use it soon after Isaac enters the room.

## Trivia

* Dannies and Coal Boys originate from the *Antibirth* mod.
Eucharist

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

## Effect

* An Angel Room Door will always spawn after every boss fight.
	+ Devil Rooms will no longer appear.
	+ The spawned door will not disappear when leaving and re-entering the boss room (except in Greed Mode).

## Notes

* Eucharist applies two effects. Like , it fixes the Devil Room chance at 100%, which forces an Angel/Devil Room to spawn whenever it can; it also fixes the Angel Room chance at 100%, so the game always chooses an Angel door over a Devil door.
	+ Now instead fixes the Angel Room chance at 100%, and the Devil Room chance at 0%.
* If the Devil Room has been visited before picking up Eucharist, an Angel Room will not replace it, despite the Angel Room chance displaying 100%.

## Synergies

* : Both Angel and Devil Room doors spawn after every boss, and the selected door will never disappear.
* : Devil rooms can still be spawned via the creation of red rooms.
* : Due to Angel Rooms being guaranteed, a large influx of items can be obtained over time.

## Interactions

* : Overridden by Eucharist.
* Tainted Lazarus: Works as though both characters have Eucharist.

## Trivia

* A eucharist is a Christian rite in which bread and wine are consecrated into the body and blood of Jesus Christ on an altar and consumed thereafter.

## Gallery

* *Afterbirth+* item concepts, including for Eucharist.
Equality!

**Equality!** is a trinket added in *The Binding of Isaac: Afterbirth †*.

## Effects

* All pickups on the ground become their doubled variants as long as Isaac's held pickups are all the same number, e.g. 65 pennies, 65 bombs, 65 keys.

## Notes

* All single keys, bombs and red hearts in a shop will become free when doubled.
	+ This is likely due to the entity being removed and a double variant being spawned, instead of simply overriding it before it spawns like  does.
* Upon picking up a non-doubled pickup that makes Isaac's pickups equal in number, a doubled variant will be spawned as well.
* Doubled pickups will not revert if Isaac's pickups become unequal.
* This trinket works well in Greed mode, doubling all pennies spawned from completing waves as long as Isaac's pickups are equal.

## Synergies

* : As long as Equality! is active, all hearts spawned will be doubled and never disappear. Hearts remain on the ground even after the effect is no longer active.
* : While Equality! is active, both rewards can be collected without the other despawning. Options? also makes Equality! easier to keep active.
* Tainted ???: T.??? will always have 0 bombs, making the trinket only possible to activate while also having 0 coins and keys (except with the Bombs are Key pill).
* Tainted Keeper: Doubled pennies from killed enemies will not despawn. All other coin types will still disappear.
Freezer Baby

**Freezer Baby** is a passive item added in *The Binding of Isaac: Repentance*.

## Effects

* Gives Isaac a familiar that shoots icicles that have a chance to petrify enemies they hit and freeze enemies they kill.
	+ Icicles deal 3.5 damage, and are fired once every 3/4ths of a second.
	+ Frozen enemies will block enemy shots, and will slide away when walked into by Isaac.
		- After colliding with an obstacle or getting sufficiently shot by Isaac, frozen enemies will explode into a ring of 10 ice tears that can slow and freeze.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a three-faced version of himself.

## Notes

* Familiars that follow behind Isaac have a certain priority in how close their position is to him over other familiars, with Freezer Baby having 5th priority.

## Trivia

* Freezer Baby originates from the *Antibirth* mod.
* Freezer Baby's item description is a reference to "Ice Ice Baby", a song by American rapper "Vanilla Ice".
Dip

## Gallery

* Sketches of monsters for the Binding of Isaac: Rebirth, including the Dip in the fourth square of the third row, formerly known as "Pooper."
* A Dip on Isaac's Last Will.

## Trivia

* The Corn has the lowest health of any enemy in the game, tied with the Fly.
* Dips are likely a reference to Gels, enemies from *The Legend of Zelda: A Link to the Past*, as they have nearly the same movement patterns.
* The name of the Dips is a pun on the term "dipshit", due to their names (Dips) and the fact that they are living fecal matter.

Dark Matter

**Dark Matter** is a passive item.

## Effects

* +1 damage.
* Adds a chance to shoot fear tears, causing enemies to run away from Isaac.

## Notes

* Fear tear effect depends on the luck stat, and the formula used to determine the chance is:

1

3
−

⌊

L
u
c
k

∗
0.1

⌋

{\displaystyle \frac1 { 3 - \left \lfloor \mathit{Luck} \* 0.1 \right \rfloor}}

	+ At base luck (0), the chance is 33.33%, maxing out at 100% at 20 luck.
	+ This makes Dark Matter significantly better at inflicting fear than  or .

## Synergies

* : Laser applies fear to enemies more consistently due to its tick rate.
* //: Chance for tears and split tears to cause fear. If the main tear causes fear, the split tears cause fear too.

## Interactions

* : Tear appearance stays the same; only the main tear can cause fear.
* : If a fear tear is fed, all burst tears cause fear. If a normal tear is fed, the burst tears cannot cause fear.
* : Tear occasionally changes appearance to Dark Matter tears and causes fear.

## Trivia

* This item is used in Darkness Falls (challenge #4).
* Dark Matter is a hypothetical form of matter that is thought to account for over 80% of all the matter in the universe. In media, dark matter is often portrayed as an evil element or demonic power, which explains why this item is found in Devil Rooms.
? Card

"Double active"

**? Card** is a special card added in *The Binding of Isaac: Afterbirth*.

## Effect

* Replicates the effect of Isaac's activated collectible.
	+ Single-use items, such as , will not replicate but instead activate and disappear.
	+ Single-use items do not disappear after using ? Card, allowing for potential multiple uses of the items.

## Notes

* The ID of this card was 43 before the Afterbirth+ expansion.
* Doesn't work with pocket activated items (such as  Tainted Bethany's  or items given by ).

## Interactions

* : Does not influence the card's effect, activating the active item only once.
* : Expends both the card and all charges with no additional benefit.

## Synergies

* : Causes the Alabaster Box to yield rewards without destroying the item or depleting any of its current charges.
* : Teleports Isaac to the I AM ERROR room of the current floor. This will consume both the Blank Card and the ? Card. If done on Chest or Dark Room, will instead spawn an I AM ERROR shopkeeper.
* : Duplicates all pedestal items and pickups in the room, without expending Diplopia.
	+ If used with another ? Card dropped on the floor in the room, allows for infinite duplication.
* : Since the card replicates the effect of moving back one room to the previous state, Isaac keeps the card having not used it as an item until the room later. This effectively gives him charge-free uses of the Glowing Hourglass.
	+ The card is no longer refunded if you enter the room with it in your inventory and use it. But if you enter a room, drop it, leave the room, come back, pick it up and use it in that room, you do get a refund as the next time you enter the room the card will be in the floor. This allows for infinite uses.
* : ? Card is used twice, giving the active item the same effect as if Isaac had Car Battery.

## Trivia

* The interaction with Blank Card presents a paradox, as Blank Card and ? Card try to replicate the effects of each other. This would result in an endless loop, so a special case was put in.
* The Blank Card interaction is one of the four reliable ways to reach the I AM ERROR room in game, alongside  in certain circumstances, using  to go beyond the 13x13 level grid, and .
* Before Booster Pack #5,  was limited to 5 uses, and uses of the ? Card counted against that limit.
Blindfolded

**Blindfolded** is a special condition exclusive to certain challenges.  The characters  Lilith and   Tainted Lilith are also blindfolded.

When Isaac is blindfolded, he is unable to fire tears and most projectiles. It also prevents attacks from other firsthand sources, such as , ,  and . However, this does not prevent attacks from items such as:

Despite being unable to fire tears, Isaac can still command familiars to shoot by holding the attack button (this includes  and ), and can still use active items.

Since blindfolded is a challenge condition instead of an existing item, it cannot be removed with Dice Rooms, , or , and does not show up on the "My stuff!" screen, or be obtained with the debug menu.

This condition is used in the following challenges:

* Solar System (challenge #6)
* Cat Got Your Tongue (challenge #8)
* Beans! (challenge #13)
* The Family Man (challenge #19)
* Blue Bomber (challenge #23)
* BRAINS! (challenge #27)
* The Guardian (challenge #30)
* Scat Man (challenge #36)
* Baptism by Fire (challenge #38)
* Hot Potato (challenge #42)

## Trivia

* Both  Lilith and The Guardian have different blindfolds that still function the same.
* Hot Potato and  Tainted Lilith do not visually have blindfolds, but the mechanic is still present.

## Notes

1. ↑ 1.0 1.1 This restriction is only lifted in Repentance.
Dogma (Item)

This article is about the item. For the boss, see Dogma.
This article is about **Dogma**, similar in appearance to The Relic.
**Dogma** is a passive item added in *The Binding of Isaac: Repentance*. It is automatically given to Isaac after defeating Dogma; the only ways to acquire it on a pedestal are either through the  or by using  on .

## Effects

* Grants flight.
* Grants a one-time -like effect. This effect wears off upon leaving the room.
* Prevents Isaac's speed from going under 1.1.
* +2 damage.
* If Isaac has fewer than 6 full hearts of health, Isaac is given enough hearts to get to six full hearts, first by restoring empty red heart containers, and then by granting soul hearts if that isn't enough.
	+ Does not affect  The Lost or  Tainted Lost normally.
	+ Keeper and  Tainted Keeper's coin heart containers are affected by the red heart healing, but they will gain Blue Flies instead of soul hearts.
	+ The Forgotten will have all his bone hearts replenished, and any soul hearts earned will go to The Soul.
	+ Bethany will gain soul charges instead of soul hearts.
	+ Tainted Lazarus will receive the flight and stat bonuses for both forms. Since defeating Dogma will swap between forms, the active character before the cutscene will *not* receive the healing and shield effect, which will instead be given to the form present after the cutscene.
	+ will take the soul hearts before they're given to Isaac, like normal.
* On Normal mode, grants  effect, reducing all damage taken to half a heart.

## Notes

* As with all items crucial to story progress (, , , , , , and ), this item:
	+ Cannot be rerolled once picked up.
	+ Does not take up an item slot for  Tainted Isaac.
	+ Still grants flight while acquiring Knife Piece 2, as it isn't removed (possible when carried over in a RERUN, using , or using  on ).
* Dogma's Holy Mantle effect does not stack with an actual Holy Mantle, but it does stack with a  effect.

## Trivia

* Dogma's in-game appearance is actually TV static, much like the boss, instead of being blue.
	+ This is because the blue is used to indicate areas that the game should apply the static effect to. This was likely done to avoid making the sprite file animated, instead simply letting the game apply the effect to designated areas when the time comes to use them. This also results in the static effect being randomized, instead of following a repeating pattern. This same trick is also what Dogma uses.

## Gallery

* Simulation of the ingame appearance for Dogma. It animates with a white TV static effect instead of being blue, both when on a pedestal or seen on the HUD.
Demon Baby

**Demon Baby** is an unlockable passive item.

## Effects

* Spawns a familiar that follows Isaac and automatically fires at enemies in its range 3 times per second, dealing 3 damage per shot.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a three-faced version of himself.

## Notes

* Familiars that follow behind Isaac have a certain priority in how close their position is to him over other familiars, with Demon Baby having 5th priority.

## Synergies

* : If used without having any familiars, a Demon Baby will be spawned for the remainder of the current room.
* : Shoots at enemies while charging up a shot, thus giving Isaac an alternative way to kill enemies while charging a shot.
* : Spawns flies as if normal tears are hitting enemies.
* : Behaves like Demon Baby, and will no longer shoot its regular tears unless Isaac has another compatible familiar. If Isaac has other familiars that Mongo Baby can mimic, its behavior alternates between Demon Baby’s and the other familiars’.

## Trivia

* In the original *The Binding of Isaac*, Demon Baby was unlocked by defeating Satan as  Eve.
Forever Alone

**Forever Alone** is a passive item.

## Effects

* Spawns a blue attack fly that orbits a long distance from Isaac and deals 2 damage per tick or 30 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.

## Trivia

* This item is used in Solar System (challenge #6).
* The name of this item is a reference to the Forever Alone meme.
Gluttony

Degraded Mini-Boss

**Gluttony** is a mini-boss and one of the Seven Deadly Sins.

## Behavior

Gluttony wanders randomly around the room and performs one of two attacks:

* Shoots 8 projectiles in all directions.
* Fires a  laser from his belly towards Isaac if he is aligned in a cardinal direction.

Gluttony deals a whole heart of contact damage.

## Unlockable Achievements

* The Book of Sin - Defeat all 7 Deadly Sins.

## Notes

* Occasionally, 2 regular Gluttonies appear in a Mini-Boss Room and the boss message will display "Isaac vs Super Gluttony".

## Trivia

* Gluttony is essentially a Vis with an attached head. The same applies to Super Gluttony, except his body is that of a Double Vis.
* The Seven Deadly Sins that these mini-bosses are based upon are, in Christian teachings, a classification of vices from which all others are derived from.
* Gluttony is a personification of one of the Seven Deadly Sins. Gluttony is the distorted desire to experience pleasures related to eating and drinking. It is a type of hedonism that could involve things such as over-eating, excessively unhealthy eating, alcohol abuse, and spending excessive amounts of money of luxurious foods, among other things. Gluttony is believed to open up a person to impulsivity, dullness in religious thought, as well as other kinds of hedonism such as lust.
High Brow

**High Brow** is challenge #2. Isaac begins this challenge with , , , , and . The goal is to defeat Mom. This challenge is unlocked by default.

## Difficulty

Starting with Number One limits Isaac's range significantly. Getting close to enemies is required to defeat them.

 The starting item set grants Isaac the  transformation, significantly increasing his survivability.

## Strategy

* Flush! can be powerful when dealing with a large number of enemies, such as in a 2x2 room. Turning all the enemies into poop allows for rapid clearing of rooms, and Petrified Poop increases the chance of those poops containing pickups.
* E. Coli can turn enemies into Poop. Given the short range granted by Number One, enemies will be more likely to do contact damage. Enemies that do not do contact damage ( Fly, Mulligan, Host, etc) are valuable, as they can be transformed into poop with no drawbacks.
	+ is a highly useful item, due to the amount of Black Flies it creates that can be transformed into poop.
	+ spawns friendly Dips when a poop is broken, making E. Coli even more valuable.
* Butt Bombs gives 5 extra Bombs to start with, which can make items or Secret Rooms easier to find in the first 2 levels.
* Because of Number One's synergy with , it is highly recommended, despite the Health cost.
* While it is slow,  can be helpful if resources are scarce in a run.
* Due to starting with the  transformation in *Repentance*, it's possible to adopt a similar strategy to  Tainted Magdalene, where Isaac touches enemies to trigger E. Coli, then breaks the resulting poop to gain health back.

## Unlockable Achievements

* Rune of Jera - Complete **High Brow (challenge #2)**.
Holy Crown

**Holy Crown** is an unlockable trinket added in *The Binding of Isaac: Repentance*.

* This trinket has a demonic counterpart in .
Head of Krampus

### Collection Grid

*(page 3, column 8, row 9)**(page 3, column 8, row 3)**(page 3, column 9, row 3)*

### Unlock Method

 Defeat Krampus

**Head of Krampus** is an unlockable activated item.

## Effects

* Fires a powerful  beam in the four cardinal directions, much like The Fallen and Krampus shoot.
	+ Has a 50% chance to rotate all beams around the player 90 degrees, similar to Krampus' second Brimstone attack.

## Notes

* Head of Krampus is one of two items that can drop by defeating Krampus.
* Each beam deals 22 damage per tick, and they tick a total of 20 times, dealing a total of 440 damage per use.
	+ Each beam deals 10 damage over 20 ticks, dealing a total of 200 damage per use.
* Damaging enemies with the effect of this item as  will spawn multiple Blue Flies.
* By standing really close to large enemies such as bosses, it's possible to hit them with multiple beams at once, dealing significantly more damage than a single beam.

## Synergies

* : Spawns red wisps in the middle ring. The wisps fire small  lasers in the cardinal directions when destroyed. The lasers deal the wisps' tear damage per tick, and can hit up to 20 times.  will not increase this damage, despite it scaling with the wisps' tear damage.
* : Doubles the damage the brimstone beams deal (for a total of  880 damage/ 400 damage per use). Doesn't double the brimstone beams' duration.

## Trivia

* This item was originally planned to appear as a Halloween Update in the original *The Binding of Isaac* but was scrapped.
	+ A scrapped item in the original game called Pumpkin Mask was very similar in effect to Head of Krampus.

## Gallery

* 3DS The icon of Head of Krampus as seen on the lower 3DS screen.

## History

* v1.031: Head of Krampus' recharge was set to 6 charges, up from 3.
Item Tags

Item tags are internal metadata, like Item quality, that were added in Repentance. The tags are used to create groups of items which are used in a few different ways.

## Examples

* Planetarium uses items tagged stars for its unlock condition.
* The Lost's Birthright rerolls items tagged nolostbr.
* Tainted Lost can only find items tagged offensive.

## Tags

For now friendly names are defined in module data.
Head Trauma

**Head Trauma** is challenge #3. Isaac starts this challenge with , , , and . The goal is to defeat Mom. This challenge is unlocked by default.

## Difficulty

* Tiny Planet and Soy Milk will make it very difficult to target enemies. Isaac will inflict only small amounts of damage, and increasing that damage will prove near impossible.
* Iron Bar can also up the difficulty as the unpredictable movement of confused enemies can make them harder to hit.
* As Tiny Planet makes it impossible to predict how a tear will hit an enemy, it is much harder to prevent knocking an enemy into Isaac.

## Strategy

* Since targeting enemies is difficult, it may help to learn where Isaac's shots converge in front of him. Practice will be a big factor.
* While it is possible to strike enemies directly behind Isaac, this has an increased chance of enemies being pushed towards Isaac.
* Rapidly hitting left and right to shoot tears will cause a better spread of tears around Isaac and make it easier to hit enemies.
* Bombs are much less effective in battle, as tears can erratically move them around the room before detonation. Bombs should not be used for any reason until all of Isaac's tears have disappeared.
* Finding Krampus is highly valuable, as obtaining  results in a significant damage increase since Isaac's tears spend a long time on screen.
* Iron Bar can cause enemies to stop targeting Isaac while they're dazed, allowing some additional freedom of movement and extra time to improvise strategies.
* Fear effects will make enemies much easier to target, as they will run in a straight line away from Isaac. This allows Isaac to drive them against a wall and target them as they become trapped.
* Transforming into  is a great strategy due to the massive number of Blue Flies that are spawned as a result. It is possible to use this transformation to effectively triple Isaac's damage output.
* It is possible to encounter an impossible room, due to enemies being too far away to reach with Tiny Planet. All rooms unlock by default after 2 minutes have passed.
	+ causes tears to fly around uncontrollably but can make it easier to hit faraway enemies.
* will turn tears into giant tears, effectively doubling damage without affecting Tears or Tear Speed.
* will turn tears into massive shields that, combined with Tiny Planet, will make Isaac nearly completely invulnerable to ranged attacks.
* will greatly boost Soy Milk's damage output.
* Due to the severe damage lowering effect of Soy Milk, rerolling Isaac's passive items is a viable strategy. This makes the , the ,  and 1 or 6 pip Dice Rooms valuable.
* dramatically reduces the difficulty of the challenge. While overall damage is still low, it is far easier to aim, and it can be fired with no charge-up time.
* allows for a much greater degree of control over Isaac's tears, eliminating the difficulty provided by Tiny Planet.
* Because of Isaac's high Tears stat, items that have a chance to cause harmful effects upon hit (such as ,  or ) are valuable.

## Unlockable Achievements

* Rune of Ehwaz - Complete **Head Trauma (challenge #3)**.
Infamy

**Infamy** is a passive item.

## Effects

* Enemy shots that hit Isaac have a 50% chance to be blocked.
	+ After effectively blocking a projectile, Isaac will briefly flash blue. Isaac in this state can still take damage from another projectile.
	+ Can block:
		- Fireballs (e.g. from  Crackle), but their lines of fire harm Isaac.
		- Fire projectiles (e.g. from Mega Satan).
		- Obstacles thrown by  Polty or  Kineti.
	+ Does not block:
		- Explosive projectiles (e.g. from Gurgle).
		- Lasers or beams.
		- Lines of fire from fireballs.
		- Projectiles from  Big Bony,  Coal Boy,  Danny.

## Notes

* Although the mask is seen only on Isaac's face, projectiles still have a 50% chance to be blocked from any direction.

## Interactions

* : Blocking effect from either item can occur.
	+ This leaves Isaac 60% chance to negate tears.
* / : Infamy's chance of blocking projectiles is applied before the shield, allowing the shield to be saved.
* : Infamy's blocking effect is applied first. Host Hat does not fire tears when a tear is blocked by Infamy.
	+ This leaves Isaac 60% chance to negate tears in any way.
* **Infamy**: Additional copies of this item, such as from  / , have no effect.
* : Infamy's blocking effect is applied first. Tears blocked by Infamy are not reflected by Metal Plate.
	+ This leaves Isaac 62.5% chance to negate tears in any way.

## Trivia

* This item is a reference to the Mask of Infamy boss.
* This item is used in The Tank (challenge #5).
* Prior to *Repentance*, Infamy's description was "Damage reduction".
Infestation 2

**Infestation 2** is a passive item.

## Effects

* Spawns an allied Blue Spider from each enemy that is killed.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a humanoid spider.

* Enemies do not spawn Blue Spiders when killed by Blue Spiders.
* Blue Flies can also spawn Blue Spiders.
* Enemies killed by familiars will spawn Blue Spiders.
* Destroying dead Shopkeepers will spawn Blue Spiders.
* Killing Pin will give one Blue Spider for each of his segments.

## Interactions

* Ace Cards: Enemies that are turned into pickups can’t spawn spiders.
* /: Enemies that are turned into poop can’t spawn spiders.
Fruity Plum

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

## Effects

* Gives Isaac a familiar that mimics Baby Plum's attack of shooting tears and propelling itself diagonally around the room. It deals 2 contact damage per tick to enemies (6 per second). It fires 15 tears per second behind itself while moving which deals 3 damage.
	+ Fruity Plum will prioritize moving towards nearby enemies.
	+ If there are no enemies, Fruity Plum loosely orbits Isaac.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a giant humanoid fly.

## Notes

* Since the achievement to unlock explicitly states you must merely **defeat** Baby Plum, regardless of the method used, sparing Baby Plum and letting her leave counts towards the unlocking of this item.

## Interactions

* : The homing effect is applied as normal which drastically improves its damage output.
* / : Doubles its contact damage and tear damage. The effect does not stack.
* : No effect.
* : Does not increase its fire rate.
* : No effect.
* : No effect.
Iron Bar

## Trivia

* Growth hormones are used to stimulate growth, cell reproduction, and cell regeneration. People often abuse growth hormone drugs in competitions to get physically stronger.
Hemoptysis

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

## Effects

* Double-tapping a fire button causes Isaac to sneeze blood, dealing damage to enemies in front of him. The sneeze deals damage equal to 1.5x Isaac's damage, knocking enemies and projectiles back. Enemies knocked back take 10 damage when hitting a wall or obstacle and deal 10 damage to other enemies they hit.
	+ The sneeze has a cooldown of 1 second.
	+ The reflected projectiles deal 6 damage if they would've hurt Isaac for half a heart, and 7 for a full heart.
* The sneeze applies a curse to enemies. Enemies under the curse will take more damage from -like laser attacks and violently explode on dying to these attacks, damaging and spreading the curse to nearby enemies. Any enemies spawned by those under the curse will also be cursed.
	+ The following attacks will deal increased damage (2x damage +3 flat damage):
		- Brimstone attacks from  Azazel/ Tainted Azazel
		- 's brimstone (not tears)
	+ The curse lasts for 5 seconds.

## Notes

* Tainted Azazel begins with an inherent version of Hemoptysis that allows him to deal full damage to cursed enemies.
* The sneeze's range is affected by the shot speed stat, and not by the range stat itself.
* The sneeze can push Bombs, pickups and enemy shots.
* The collision damage can be used to damage Hosts while their skulls are lowered.
* Brimstone lasers shot by enemies who are not charmed, such as Monstro II, will also do increased damage to cursed enemies

## Synergies

* : The sneeze will still set enemies on fire, but not cause explosions, similar to its interaction with .
* : Chance to sneeze in all cardinal directions.
* : The sneeze reflects enemy shots.
* : Multiple sneezes are applied around the character.
* : Shoots two sneezes diagonally instead of one straight forward.

## Interactions

* : The sneeze causes an explosion. The explosion deals additional damage equal to 3x Isaac's damage +10 and will not hurt Isaac.
* Tainted Azazel: The innate sneeze ability is entirely separate from Hemoptysis, and so the sneeze can be triggered twice in quick succession. However, triggering the sneeze from Hemoptysis will cancel Tainted Azazel's brimstone charge, meaning that this item is largely ineffective as this character.

## Trivia

* Hemoptysis is the medical term for coughing up blood.
