## Effects

* Walking in a circle will spawn a pentagram symbol on the floor, which deals 10 damage per tick to non-flying enemies within it.

## Notes

## Trivia

* The pickup quote may be a reference to the Pearl Jam song of the same name.

Goat Head

{{:{{{1}}} | {{{1}}} | {{{2}}} }}

**Goat Head** is a passive item.

## Effects

* A Devil Room / Angel Room Door will always spawn after every boss fight, excluding the first floor and floors after Utero II/Womb II/File:DLC Indicator.pngScarred Womb II.

## Notes

* Accepting a deal with the devil will prevent any Angel Rooms from appearing, meaning that Isaac needs to acquire the Goat Head in a Curse Room, Golden Chest, Red Chest or with Credit Card in order to force Angel Rooms to appear.
* Even if taken after a boss is killed, Goat Head will force a Devil / Angel Room Door to spawn on that floor. The door will always stay opened, unless Goat Head is re-rolled with D4, D100, or a Dice Room.
* Angel Rooms and Devil Rooms will still remain open even after exiting the Boss Rush room.
* File:NoDLC Indicator.png Goat Head and The Book Of Belial are the only items that will ensure Angel/Devil Rooms on every floor between Basement I and Utero II.
* File:DLC Indicator.png Goat Head will not force a Devil / Angel Room Door to open if the Boss Fight was in a narrow room.

## Trivia

* This item is a reference to how goats and their blood were often used as a common sacrifice proxy. This is even more evident by the pickup quote.

* Template:Lord of the Flies

## Notes

* All obtained bomb modifiers are applied to BBF as well.
* The blast can damage Isaac.
* For the first few moments after entering a room, the familiar will do contact damage instead of exploding. This means the familiar will not blow up in Isaac's face if there is an enemy right next to the familiar's starting point.However,it may kill enemies that explode on death.

## Synergies

* Hot Bombs - BBF leaves fire on the floor which will not damage Isaac.
* Mr. Mega - BBF will deal much more damage upon exploding.

## Effect

* Grants charged tears that can be fired in a tight burst of four.
* Taking damage while charging will teleport Isaac into another room.

## Notes

* Holding a full charge does not teleport Isaac.

* The color of Isaac's cursed eye will indicate what state it currently is in:
	+ White: Inactive
	+ Black: Charging up
	+ Flashing black and white: Fully charged

## Interactions

* Anti-Gravity - Overrides Anti-Gravity.
* Blood Clot - Unless playing as Cain, no damage or range bonus will be given from the item, as the blood clot covers the other eye.

* File:DLC Indicator.png Black Candle - Teleport effect removed.
* File:Afterbirth† Indicator.png Incubus - Incubus fires 4 tears.

## Synergies

* Guppy - Fires four streams of flies.
* Ipecac - Fires four explosive shots.
* Cupid's Arrow, Sagittarius - Fires four piercing shots.
* Mutant Spider - Fires four sets of four shots.
* The Lost - Since getting hit would instantly kill the Lost anyway, the teleporter effect is null.
* Keeper - Fires four sets of three shots.
* Dr Fetus - Bombs will now fire at a rapid rate.

## Trivia

* This item may be a reference to Edgar Allan Poe's "The Tell Tale Heart" where the narrator talks about murdering an old man because of his "evil eye", which is described to look like The Cursed Eye.
* When Keeper charges up his shots his eye turns into a dollar sign.

## Interactions

* Items that occasionally block damage like Infamy, Cone Head, or Metal Plate can also block the effect of this item, wasting the charge.

* The Big Fan orbits independently rather than occupying one of the three defense orbital slots.

## Interactions

The **Cursed** **Yum Heart** is an activated item.

## Effects

* You have a 1 in (200/xy) chance of getting a negative outcome, with x representing half the amount of heart containers and soul hearts on hand (due to the game recognizing half hearts as 1 HP each) and y representing how many times the Cursed Yum Heart has been used plus one.

A Card Against Humanity

Template:SpecialCardsHeader
{{:{{{1}}} | {{{1}}} | {{{2}}} }}

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

## Notes

* Poop will not fill tiles with obstacles, even if they have already been destroyed.
* The process is not instant and the room will not get filled if Isaac leaves before it's done filling.
* It is more beneficial to use the card in a large-sized room as it will create more poop piles.

## Synergies

* Midas' Touch - Spawned poops have a great chance to turn into golden poops.
* Petrified Poop - Greatly increases the chance of finding a pickup when destroying poop.
* Leo / Thunder Thighs / The Nail - Allows all the poop to be easily destroyed.
* File:DLC Indicator.png Infested! Pill - Every pile of poop spawns a blue spider.
* File:DLC Indicator.png Lil Larva - Every pile of poop spawns a blue Fly.

## Interactions

* File:DLC Indicator.png Brown Cap - All the poop explodes in a chain reaction once one is destroyed.

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

## Effects

* +0.2 Speed.
* Grants 6 black hearts.

* Adds a chance to shoot fear tears.
* Template:Leviathan

## Notes

* The chance to fire a fear tear depends on Isaac's Luck stat, and goes up to 100% at 85 Luck.
* Does not remove soul hearts.
* As it removes all red heart containers, other devil deals can be taken for "free" as long as Abaddon is taken last while still having at least 1 container.
* Has no negative trade-off when taken as ???, except the revoked chance of an Angel Room.
* Since Keeper is not allowed to have Soul or Black Hearts, Abaddon will simply take away all his health coins; resulting in instant death.
* Can always be taken when offered as a 3 soul heart devil deal. Even if the player only has one or two soul hearts, six black hearts will be granted after taking the item.

## Trivia

* In the Hebrew Bible, the name Abaddon is used in reference to a bottomless pit, often appearing alongside the place of the dead (which is known as Sheol), meaning the land of the dead. The actual Hebrew word Abaddon (אבדון - pronounced *avadon*) means "doom".
* Abaddon is the Hebrew equivalent of Apollyon.
* In the New Testament Book of Revelation, an angel called Abaddon is written as the king of an army of locusts; his name is first transcribed in Greek (Revelation 9:11 – "whose name in Hebrew Abaddon").

	+ +1.50 range
	+ +0.7 tears
	+ +0.20 shot speed
* The effect is lost any time Isaac gains or loses red hearts.

## Notes

* This item would especially go well with Eve, since she starts with Whore of Babylon, and is the only character that can gain Whore of Babylon's effect at 1 heart.
* This item has no effect on Blue Baby, since he cannot gain red hearts.
* If a Strength card is used when the user only has soul hearts, the effect is granted and persists even when the red heart container is removed when a new room is entered.

Lost Fly

{{:{{{1}}} | {{{1}}} | {{{2}}} }}

**Lost Fly** is a passive item added in the *Binding of Isaac: Afterbirth* expansion.

## Effects

* A familiar fly that moves in a straight line and attaches itself to the first obstacle or wall it comes into contact with in each room.
	+ The Lost Fly will then move around the room functionally similarly to the Guts.
* If any enemies walk into its path, it will deal 7 contact damage per tick.
* If the obstacle it is attached to is destroyed then it will continue rolling in the direction it was previously travelling until it meets another wall or obstacle.
D10

{{:{{{1}}} | {{{1}}} | {{{2}}} }}
The **D10** is an activated Item.

## Effect

* Upon use, turns all of the enemies in a room into different ones.

## Notes

* Rerolling an enemy will replace it with an entirely new one from any floor, making it dangerous to use early on in the game (as you could get enemies from the Depths or later).
* The D10 generally will not reroll bosses, but can reroll enemies spawned by bosses.
* The D10 can reroll the Blighted Ovum's ghost.
* Using this item can cause some rooms to become impossible to clear. Jumping or flying enemies may become trapped behind rocks after being rerolled, and therefore become unbeatable.
	+ Sealed doors open after 2 minutes, so even if a room is impossible to clear, the run is not over.
* File:DLC Indicator.png Fly enemies will only be rerolled into other fly enemies.
* File:DLC Indicator.png The red and yellow flies can't be rerolled anymore. (even if enemies can be rerolled into them)
	+ Camillo Jr are also immune to being rerolled.
* Using this item on any monster with several pieces will reroll every piece into a monster. Mr. Maw and Gemini's cord dots are considered pieces, each turning into a new monster.
* Using this item in a room with Grimaces will turn them invisible. They will not fire, but the space they occupied will prevent Isaac from moving through it like an invisible wall.
	+ File:DLC Indicator.png There is a chance of getting a frozen-in-place Papa Fly after a reroll. It will occupy the space used by the rolled Grimace even after leaving the room or floor. Dying will force it to despawn.
* Using this item in a room with Mom's Hand can be very dangerous, as unless they have already landed, they will be directly on top of Isaac, resulting in the new monsters spawning directly on top of Isaac, instantly dealing contact damage.
* Using this item with the Broken Remote will first teleport the player and then reroll the enemies in the new room.
* Using this item then exiting the room, such as by teleporting or a bombed door, will cause the enemies to be in their original forms upon your return.
* This item is of little utility in the Chest or in the Dark Room because D10 doesn't reroll bosses and most of the rooms are populated by bosses.

## Bugs

 ****Bug!**** Rarely, an enemy can be rerolled into the mask half of the Mask + Heart enemy, and the mask will die instantly.
 ****Bug!**** File:Afterbirth† Indicator.pngIn rare times,when the item is used,it have a small chance to reroll a enemy to a blue tinted Pooter,like the fly when spawns Brown Nugget.The fly will not attack Isaac,it only attacks enemies.

BFFS!

{{:{{{1}}} | {{{1}}} | {{{2}}} }}

**BFFS!** is a passive item.

## Effects

* Increases the size and doubles damage of familiars.

## Notes

* Familiars that do not deal damage (like the pickup generation variants) only obtain a cosmetic increase in size but do not gain any benefit.
* Familiars summoned by a trinket or by Monster Manual are also affected by this item.
* Has no effect on Rotten Baby, as it is not the item itself which does damage, but rather the Blue Flies it spawns.
	+ The Blue Flies benefit from Hive Mind instead.

## Interactions

* BBF - Increases both the size and damage the explosion inflicts. This also makes it easier for Isaac to get hit by the blast.
* Isaac's Heart - Increases the size of the hitbox, making it easier to get hit.

## Synergies

* Dry Baby / File:DLC Indicator.png Fart Baby - The baby's increased size will make it easier to trigger the Baby's effect.
* Guppy's Hair Ball / Samson's Chains - The increased size makes it much easier to hit objects/enemies while swinging the familiars.
* File:DLC Indicator.png Incubus - Incubus deals double your damage instead of copying it. Effectively doubles Lilith's damage.

## Trivia

* BFF stands for ***B**est **F**riends **F**orever*.
* This item is used in Challenge #19 (The Family Man).

Bumbo

{{:{{{1}}} | {{{1}}} | {{{2}}} }}

**Bumbo** is a passive item added in Afterbirth.

## Effect

* Spawns a Familiar which floats around the room and picks up any nearby coins. Every 6 coins, Bumbo will evolve to a new form, except for level 4, which takes 12 coins.

 **Level 1:** Bumbo just collects coins to level up.
 **Level 2:** Bumbo gains a body and crawls around the room, occasionally dropping random pickups
 **Level 3:** Bumbo now fires tears in the same direction Isaac does. Any enemy hit by Bumbo's tears has a chance to drop a coin.
 **Level 4:** Bumbo no longer fires tears but instead will chase enemies slowly and deal contact damage. Bumbo will also sometimes randomly drop bombs.
* After reaching level 4 (and a very low chance before level 4), Bumbo will also continue to collect coins and drop random pickups, trinkets, and chests, similar to Bum Friend, but can also drop pedestal items.

## Notes

* Bumbo can fly over pits and obstacles.
* If Bumbo consumes an absurd amount of coins while level four, Bumbo can become level one again [Unsure if bug]
* If Level 4 Bumbo targets Mega Satan's head, Bumbo will attempt to "chase" him the entire fight by standing in the middle of the room.
* Bumbo's bombs will take on the properties of Isaac's bomb upgrades.
* Bumbo cannot pick up sticky nickels, and will hover over them. Level 4 Bumbo can eventually bomb the nickel loose.
* Bumbo will pick up lucky pennies, without additional benefit to evolution or drops.
* If Bumbo drops a pedestal item, it will be pulled from a random item pool.

## Synergies

* Bomber Boy: Bumbo's bombs explode in a cross shape.
* Head of the Keeper: Coins dropped from hitting enemies can level Bumbo up quickly.

## Interactions

* Box Of Friends: Will spawn a level 1 Bumbo regardless of the original Bumbo's current level.
* Bum Friend: The bum friend will follow Bumbo instead of Isaac.
* Hot Bombs: Does not affect Bumbo's bombs.
* Keeper: Not recommended, as the coins Bumbo collects could have been used to heal Keeper.

## Trivia

* Bumbo is the main character of his own game designed by Edmund McMillen.

## Gallery

* Bumbo Level 1
* Bumbo Level 2
* Bumbo Level 3

Gimpy

{{:{{{1}}} | {{{1}}} | {{{2}}} }}

**Gimpy** is a passive item.

## Effects

* Whenever Isaac takes damage, there is a chance that a Soul Heart or a Black Heart might spawn.
* Enemies have a chance to drop a Half Red Heart after being killed.

## Notes

* Gimpy's Soul Heart drop chance depends on the Luck stat, and goes up to 50% at 22 Luck.

## Synergies

* Blood Donation Machines/IV Bag - Allows Isaac to take red heart damage for chance of Soul Hearts and money.

## Trivia

* Gimpy is a reference to the movie *Pulp Fiction,* in which a minor character known as "The Gimp" is depicted wearing a leather BDSM suit including a mask much like the one Isaac wears in possession of Gimpy.
* The "Sweet Suffering" flavor text is a reference to BDSM. Specifically, it references masochism, which is when sexual pleasure is derived from pain.

Breakfast

{{:{{{1}}} | {{{1}}} | {{{2}}} }}

**Breakfast** is a passive item.

## Notes

* If an item pool runs out of items, it will only contain Breakfast from that point onwards.

## Synergies

* File:Afterbirth† Indicator.png Potato Peeler: Increases the usefulness of the item once item pools are depleted (i.e. in a breaking run), as the heart containers can be converted into Cubes of Meat, as well as increase the player's damage and range.

## In-game Footage

Bloody Lust

{{:{{{1}}} | {{{1}}} | {{{2}}} }}

**Bloody Lust** is an unlockable passive item.

## Effects

* Damage increases as Isaac receives damage. The damage increase stays for the whole floor, but resets upon entering a new floor.
	+ The first three times Isaac is hit, his damage is increased by 0.5.
	+ The next three times Isaac is hit, his damage is increased by 33%.
	+ Any damage taken past the sixth hit does not further increase damage.
* Isaac becomes redder as his damage increases.

## Notes

* Samson starts with this item by default.
* If Forget Me Now or a 5-pip Dice Room is used, the damage boost will reset.

## Synergies

* File:Afterbirth† Indicator.png Dull Razor - Safely provides the damage boost without needing to actually take damage.
* IV Bag - Allows Isaac to increase his damage at any time at the cost of red hearts.
* Libra - As Isaac's damage increases, the rest of his stats increase as well, though they will reset at the start of a new floor.
* Placenta - Provides a 100% safe, albeit extremely time-consuming, method of maxing out the damage boost free of charge. Simply take the necessary hits and wait for Placenta to regenerate the lost health.

## Trivia

* In the original *Binding of Isaac*, Bloody Lust only lasted for one room and the damage increase was triggered by killing enemies.
	+ File:DLC Indicator.png Lusty Blood now has the effect of the original Bloody Lust.
* On the character select screen, Samson's starting item is spelled as "Blood Lust".

Godhead

{{:{{{1}}} | {{{1}}} | {{{2}}} }}

## Effects

* +0.5 Damage.
* -0.3 Tears.
* +1.2 Range.
* -30% Shot Speed.
* +0.8 Shot Height.
* Grants homing tears.
* Tears gain a damaging aura.

## Synergies

* A Lump of Coal - The size and damage of the aura increases as long as the tear is on screen.
* Brimstone - Brimstone laser becomes slightly stronger and homes towards enemies. Laser does not receive the damaging aura.
* Chocolate Milk - Charging shots increases the size of the aura but does not affect its damage.
* Epic Fetus - Causes the crosshair to home in upon enemies, and hits harder. Missiles do not have a damaging aura.
* File:DLC Indicator.png Explosivo - Causes damaging aura to grow once attached to an enemy.
* Piercing Tears: The piercing effect stops tears from disappearing on contact with enemies, giving the aura more time to cause damage.
* Spectral Tears: Similar to the piercing effect, items which provide a spectral effect allow tears to pass through objects, giving the aura more time to cause damage.
* File:DLC Indicator.png Glass Cannon: The huge tear gains the homing ability and fully scaled damaging aura, able to cover most of the screen with extreme damage.
* Ipecac - Explosive projectile tears become slower and smaller, but retain the damaging aura and homing effect.
* The Ludovico Technique - Tear increases in size and gains the damaging aura effect.
* Rubber Cement - Tears stay longer on screen, increasing the amount of the damage the aura can do.

## Interactions

* Mom's Knife: Does not get the damaging aura, but does get all other effects.
* Technology: Gets the homing effect but not the aura.

## Trivia

* Godhead is another term for Godhood, or overall Divine nature.
* The Godhead bears strong resemblance to the Eye of Providence, Eye of God or The Eye That Sees All, a common religious symbol also used in Christian religions. The three edges of the triangle may represent each part of the Holy Trinity.
* Godhead is arguably the hardest/most grueling item to unlock in Rebirth and Afterbirth, as it requires having to kill every final boss, on hard mode, with The Lost.
* The three triangles on the corners of the **Godhead** icon may be a reference to The Mind, The Body, and The Soul items.
* This item appears in the Afterbirth† release date trailer.

Guppy's Collar

{{:{{{1}}} | {{{1}}} | {{{2}}} }}

**Guppy's Collar** is a passive item.

## Effects

* Isaac has a permanent 50% chance to resurrect on death.
	+ Resurrection leaves Isaac at half a red heart.
	+ Guppy's Collar takes priority over all other resurrection items when activated.
* Template:Guppy

Template:PlatPS4 FQTL 13FX (Curse room adjacent to spawn)

## Trivia

* This item is a tribute to Edmund's cat Guppy.[1]
* This item may also be a reference to the Schrödinger's Cat thought experiment.
* It is possible to obtain two collars by finding one in a red chest, without picking it up, and then finding another collar in a different red chest. However, this does not have any additional effects and does not count towards transforming into Guppy.
* Resurrecting in a Curse Room may trap Isaac if he has no way of recovering health or exiting them without losing health.

## Bugs

 ****Bug!**** After dying with Guppy's Collar, forcing the game to close then re-opening the game and continuing the run will reactivate Guppy's Collar, granting a 50% chance to resurrect. This can be repeated after each death, effectively granting infinite lives.
