Red Stew

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

## Effects

* On pickup, fully heals Isaac and gives him a temporary +21.6 damage up.
	+ The damage upgrade scales down to 0 over the course of three minutes. Due to how the damage formula works, the damage upgrade scales down faster over time, starting at -~0.015 per half second and increasing to -~.1 per half second as the bonus approaches 0.
	+ While Red Stew is active, Isaac gains an effect similar to , gaining a small damage bonus every time he kills an enemy. This damage bonus persists between rooms and floors, allowing Isaac to sustain the temporary damage up for longer than he otherwise would if he manages to kill many enemies. This effect disappears once Red Stew's damage bonus completely runs out.

## Notes

* Due to the high amount of damage you temporarily gain, this item is extremely effective in Greed Mode, as all fights are done within the same room and you are easily able to make the most out of it.
* The damage bonuses on kills can exceed the damage increase given from picking up Red Stew.
* The default length of Red Stew is 5390 game frames, which is just short of 3 minutes. (This will be the length if no enemies are killed during the effect.)

## Synergies

* : The damage up becomes permanent and if Isaac kills enemies fast enough it can increase even further.

## Interactions

* Ace Cards: Turning enemies into pickups doesn’t grant the damage bonus.
* /: Turning enemies into poop doesn’t grant the damage bonus.
* Freeze Effects: Enemies that die from being frozen don't grant the damage bonus.
* : Picking up another stew will reset the bonus to its full amount.
* Tainted Bethany: Grants 12 blood charges.

## Trivia

* Red Stew originates from the *Antibirth* mod.
* In the Book of Genesis in the Bible, Esau sold his birthright to his younger brother, Jacob, for a serving of lentil stew, so that Jacob would receive their dying father's blessing instead.
* Prior to v1.7.5, Red Stew was the only unlockable item added in Repentance with a quality of 0.
Mr. Boom

**Mr. Boom** is an activated item.

## Effects

* Places a large Bomb similar to ones produced by .
	+ Deals 110 damage.
	+ Deals 185 damage.
	+ Despite slightly different appearance, the bomb is functionally identical to a Mr. Mega bomb, being compatible with all bomb modifiers.

## Synergies

* : Spawns wisps in the middle ring, looking like bombs. The wisps spawn miniature homing bombs when destroyed. These miniature bombs behave the same as ones created by , with the exception that they deal 100 blast damage instead of 50.
* + : The Mr. Boom bomb is affected by remote detonator.

## Interactions

* : No further improvement in damage or blast radius.

## Gallery

* 3DS The icon of Mr. Boom as seen on the lower 3DS screen.

## Trivia

* When used, the sprite of Mr. Boom appears to have a missing tooth, but the pedestal sprite and official artwork from Four Souls shows it has a perfect set of teeth.
Purgatory

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

## Effects

* Spawns a red crack in the ground somewhere in the room while Isaac is in a room with enemies. Walking over the crack summons a ghost that homes in on the nearest enemy, exploding when it hits it. After the ghost is summoned, cracks will keep showing up in the room until it is cleared.
	+ The ghost spends one second spawning in before it attacks.
	+ The ghost deals double Isaac's damage per tick, up to 4 times.

## Notes

* Only one crack is active at a time.
	+ The amount of cracks does not increase with additional copies of the item.
* The explosion does not hurt Isaac.
* If a crack is stepped on and the room is cleared before the ghost spawns, it will fly to a random location and explode there.
* The explosions from the ghosts will destroy enemy tears.
* Cracks don't spawn in Challenge Rooms.
* Friendly enemies can be killed by the ghosts.
* The ghosts aren't considered familiars, therefore they're unaffected by items or trinkets that alter familiars or their behavior, such as , ,  or .

## Interactions

* : Walking over cracks will not summon ghosts while under the effect of Dark Arts.
* : When used on Purgatory, turns the item into , a unique item usually only able to be obtained by killing the boss Dogma.

## Trivia

* Purgatory is a place or state of suffering inhabited by the souls of sinners who are expiating their sins before going to heaven.
* Purgatory is one of only five items to appear in both the Angel and Devil item pools, the others being , ,  and .
Options

The Options are a page from which the player can adjust different settings. They can be accessed from the main menu and the pause menu.

## Options.ini

The *options.ini* file, located at *C:\Users\ (User Name) \Documents\My Games\Binding of Isaac Repentance*, can be used to change several settings that are not available from the in-game menu. To avoid redundancy, only settings that are not available in the game options are listed in this table.

## Trivia

* The "Found HUD" option is a reference to "Missing HUD", a popular external program that would display Isaac's stats before it was officially added to the game.
* The "Charge Bars" option is based on a popular Steam Workshop mod by user Wofsauge.
* The French language was a Steam Workshop mod by user biobak that was officially implemented into the game.
* The game's files contain several unused assets that would most likely have been available in the options :
	+ A separate "Gamma" menu that would have allowed players to independently set Gamma, Exposure and Offset.
	+ Sprites for option names that read "Aim lock", "Console", "Touch Mode", "Pen Opacity" and "Rumble".
	+ Sprites for text that reads "Graphics" in the header color, indicating that there might have been a separate section in the options to change graphics-related settings.
Pay to Win

## Effects

* Shop Restock Machines or "Restock Boxes" always spawn in Treasure Rooms.

## Notes

* The trinket's effect applies when the floor is generated, so it will only take effect if already held when entering a new floor. This means that finding it on a floor will not change the Treasure Room on that floor, nor will dropping it remove its effect on that floor's Treasure Room if Pay to Win was held when the floor was entered.
	+ This also means that the trinket will have no effect in the Ascent, since it is based on previously generated floors.
* This trinket does not affect the two Treasure Rooms spawned in ???.
* In Greed Mode, this affects both normal and silver types of Treasure Rooms.
* When brought to the alternate path floors, there is a chance of the treasure room having one extra item available to be picked up alongside the usual choice of two items.
* Restock boxes will not appear in the Mirrored World's Treasure Room.

## Synergies

* : Can be a powerful combination for when Isaac is not  Tainted Cain as he can craft multiple item pedestals in the Treasure Room which can be rerolled.
* : Treasure Rooms will always contain two choice items in addition to the Shop Restock Machine.
	+ In Downpour, Dross, and Mines, Pay to Win by itself can sometimes spawn the combined Treasure Rooms, even without More Options. Having both doesn't guarantee the combined effect.
		- For Ashpit, Mausoleum, Gehenna, and Corpse, this combination does work correctly for normal-sized Treasure Rooms, but not thin ones.

## Trivia

* The item is a reference to microtransactions, which are common in modern video games. They serve the "pay-to-win" goal by making it either impossible or extremely tedious for players to either progress through the game (with so-called "roadblocks") or earn certain features such as weapons unless they purchase their "way out."
Ocular Rift

**Ocular Rift** is a passive item added in *The Binding of Isaac: Repentance*.

## Effects

* Gives Isaac a chance to fire tears that create rifts where they land, which damage nearby enemies and pull in enemies, pickups, and tears/shots from all sources for 2 seconds.
	+ Rifts deal 0.5x Isaac's damage twice each tick (3x Isaac's damage per second), and enemy shots pulled into the rift will damage other enemies.
	+ The size of the rift increases with Isaac's damage.

## Notes

* The chance to fire a rift tear depends on the luck stat, and the formula used to determine the chance is:

min
(

1

20
−

⌊

L
u
c
k

⌋

,
20
%
)

{\displaystyle \min(\frac1 { 20 - \left \lfloor \mathit{Luck} \right \rfloor},20\%)}

	+ At base Luck (0), the chance is 5%, maxing out at 20% at 15 Luck.
* Not recommended for Mother fight as the rift accelerates inbound projectiles, making them harder to dodge.

## Tips

* Rift tears can be used to move pickups that might be located behind spikes.
	+ Placement of the rifts is easier with items which provide a degree of control over tears, e.g. .
* Because the pull of Ocular Rift affects enemy shots, it can be used defensively to dismantle the curtains of bullets that Isaac would otherwise have to dodge. This is especially useful for bosses like Hush and Delirium.

## Synergies

* : Rifts may appear where a brimstone beam hits rock, walls or enemies.
* / : Causes many smaller rifts to also spawn.
* : Each tick of damage has chance of creating rift, which will be slightly bigger in size.
* : Works similarly to Brimstone.
* : Works similarly to Brimstone.
* : May spawn a line of rifts where the laser travels.

## Interactions

* : Overridden by Epic Fetus.
* : Overridden by Mom's Knife.

## Trivia

* In *Antibirth*, this item was called Oculus Rift, a reference to the virtual reality headset brand of the same name; this potentially was changed due to copyright issues.
	+ Its tear chance would also directly scale with Luck, being 100% at 13 Luck.
* This item´s description is likely a reference to a quote by the philosopher Friedrich Nietzsche which goes "Stare long enough at the abyss and it will stare back at you"

Pluto

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

## Effects

* +0.7 tears
* Significantly shrinks Isaac, allowing him to squeeze between objects and makes some enemy shots pass over him.

## Notes

* With enough speed and the correct angle or being pushed by an explosion, it is possible to cross pits and pass through obstacles, allowing Isaac to reach places he usually isn't able to reach.
* Pluto can stack with other size reduction effects.
* May allow Isaac to squeeze through the walls and floors in Crawl Spaces and 2nd/3rd phase of Rotgut. Passing through the outermost wall in an unintended direction leads to the I AM ERROR room.
* The decrease in size makes dodging certain tear effects easier, most notably Hush's continuum tears, and Dogma's feather attacks from their respective second phases.

## Interactions

* : Split tears' range is dropped drastically. Range ups do not mitigate the effect.
* : Drops the bombs' range drastically despite no change in the range stat, greatly increasing chance of self-damage. Range ups do not mitigate the effect.

## Trivia

* Pluto originates from the *Antibirth* mod. In *Antibirth*, it would also give a range down.
* Pluto's effects reference the planetoid Pluto's nature as a dwarf planet.

### Unlock Method

 Defeat The Lamb

**Portals** are enigmatic entities that appear  on many floors/ only in The Void. They continuously spawn enemies until they are destroyed or spawn a certain number of enemies.

Portals spawn different enemies depending on the floor they appear on.

In The Void, Portals spawn enemies based on the theme of the room they are in.

## Lil Portal

### Stage HP

### Found In

**Lil Portals** are entities that only appear in Mausoleum and Gehenna. They continuously spawn fly and spider enemies until they are destroyed. There can be a max of 4 spawned monsters alive at once. Monsters they can spawn include:

## Lil Portal (Flies Only)

There is a variant of the Lil Portal with the ID 306.1.1 that looks and behaves identically to regular Lil Portals but will only spawn Fly related monsters from its regular pool.

## Entrance Portal

A special version of the Portal (dubbed the "Entrance Portal" to avoid confusion) serves as the entrance to The Void. It is found in ???, but can also be found after defeating Mom (5% chance and only if Isaac has 10+ tear damage or 20+ items), Mom's Heart/ It Lives (10% chance), Isaac/ Satan (15% chance), ???/ The Lamb (20% chance), or Mega Satan (50% chance).
The Entrance Portal room in ??? gets darker the closer the player is to the portal.

## Notes

* Charming a Portal with  or similar items will cause the Portal to spawn permanently charmed enemies similar to the .
	+ As a result, a permanently charmed Death's Head can spawn from charmed Portals on Chapter 3 and remain permanently invulnerable. This is the only known method of charming an invulnerable enemy.
* If a portal is spawned in ???, Chest, Dark Room or Home via Debug Console, the Portal will despawn a few seconds before spawning any monster.
* If Portals aren't unlocked, certain enemies will spawn in their rooms instead, depending on the floor the room is in. For instance, Frowning Gapers spawn as Portal placeholders on Chapter 1 floors, whereas Vises spawn as Portal placeholders on Chapter 4 floors.

## Gallery

* The room darkening as the player approaches the portal.
* The Entrance Portal next to the Chest after defeating Isaac. Notice the distortion effect on the chest.
* A portal's idle animation, as found in the game files.

## Trivia

* Before v1.06.0185, portals continually spawned enemies until they were defeated.
* Portals were able to spawn Bosses such as The Haunt on floors such as the Cathedral. This was later removed.
* As of Booster Pack #5, Portals will now leave a Purple "blood" splatter when killed by the player. This effect is only for aesthetic purposes. Formerly, they left the generic Red blood splatter.
* Lil Portals resemble Warp Zones from *Super Meat Boy*.

### Collection Grid

*(page 4, column 13, row 1)**(page 4, column 13, row 1)**(page 4, column 14, row 1)*

 **Number Two /  No. 2** is a passive item added in *The Binding of Isaac: Afterbirth*.

## Effects

* Holding any fire button/direction for 2.35 seconds causes Isaac to drop a free  bomb. This includes charging or directly controlled attacks. Only 1 Butt Bomb can be dropped per charging cycle, so it is required to stop firing and then charge again to drop another Butt Bomb. Taking Damage will interrupt the cycle.
	+ There is a visual fart effect whenever a Butt Bomb is placed.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a walking pile of poop.

## Notes

* Essentially grants unlimited bombs, as the charge time can be repeatedly reset by pressing and releasing the fire button. This allows Isaac to bomb an unlimited amounts of tinted rocks, get into every Secret Room and Super Secret Room, etc.
* Increases difficulty of poop-themed bosses such as Dingle, as Butt Bombs restore 25% of maximum HP to the bosses when they explode.
* The spawned butt bombs will be affected by bomb modifiers, excluding .
* This item can be great for clearing the early floors of Greed mode, due to the butt bombs dealing room-wide damage every few seconds.

## Interactions

* Number Two, ,  and  all have the same charge time, allowing Isaac to easily utilize them at same time.
* /: Shoots a flame behind Isaac with each fart
* : The butt bombs have a chance of spawning pickups or trinkets upon exploding.
* : Bombs placed by Number Two will not explode until Remote Detonator is activated.
* : Only 1 bomb is placed by Number Two.
* : No effect.

## Trivia

* This item's name was changed from No. 2 to Number Two.
* This item's visual effects gets overlapped by black poops darkening one, at least pre-Repentance.
Pageant Boy

**Pageant Boy** is a passive item.

## Effects

* Spawns seven coins around Isaac.
	+ These coins may be any normal type with their respective usual chances: Pennies, Nickels, Dimes,  Lucky Pennies,  Sticky Nickels or  Golden Pennies.
	+ Denomination of coins that spawn is not affected by luck.

## Synergies

* : On the low chance this item spawns in Womb or Corpse, coins dropped will instead be replaced by drops from Nuh Uh!'s drop table.
Neptunus

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

## Effects

* When Isaac is not firing tears, a charge bar will start to fill up. Holding down the fire button will release all stored tears in rapid succession.

* The charge time and maximum tears per charge scale with Isaac's tears stat, with higher tears charging faster and having more.

## Notes

* While at 0 charge, Isaac fires at his normal tear delay, essentially meaning there is no downside.
* Rapidly tapping the fire button will not empty the charge, and can be used as a permanent massive increase to fire rate.
* This item has no observable effect when used as  Tainted Lilith or  Tainted Forgotten.

## Synergies

* : The passive charge of Neptunus does not disrupt Camo, and the initial burst of damage is enhanced by Neptunus.
* : Neptunus' passive charge overrides Chocolate Milk's active charge. Tear damage is determined by how charged Neptunus is.
	+ Once Neptunus' charge is used up, Isaac will fire uncharged Chocolate Milk tears, resulting in a much lower damage output than without Chocolate Milk.
	+ **Chocolate Milk** + : Isaac will not fire any tears during the Kidney Stone burst.
	+ **Chocolate Milk** + : Isaac will not be able to fire any tears.
* : Tear bursts stack, firing a very large number of tears in combination with each other.

## Interactions

Overrides Neptunus:

* Azazel/
* + However,  + Tech X does work with Neptunus.

Other interactions:

* : Overridden by Neptunus.
* : The charge bar is not present and charged tears are released instantly.

## Trivia

* Neptunus, as well as , was designed for the original *Antibirth* mod, but never actually implemented until *Repentance*.
* Neptunus' effects and pickup quote reference the Roman god of the sea, Neptune.

This article is about an item affecting Treasure Rooms. For a similar item affecting Boss rewards, see There's Options. For a similar item affecting room clear rewards, see Options?.
**More Options** is an unlockable passive item added in *The Binding of Isaac: Afterbirth*.

## Effects

* Two item pedestals are presented in every Treasure Room. Only one can be taken; the other will disappear.
	+ Having multiple copies of More Options will not have extra effect.

## Notes

* Small Treasure Rooms only present one item, nullifying this item's effect.
* If the Treasure Room has already been entered and the item was not taken, then picking up More Options later on the same floor will not retroactively add a second item to the room.
	+ If the Treasure Room has not been entered on the same floor More Options was picked up, then it **will** contain two items.
* The very rare Treasure Rooms that have either no item or two items that can *both* be picked up will be replaced with a one-out-of-two choice room, like other Treasure Rooms. In the latter case, this is a downgrade.
* In Downpour / Dross / Mines / Ashpit / Mausoleum / Gehenna, Treasure Rooms will have two known items and one unknown item, instead of the usual one known and one unknown.
* In Downpour II / Dross II, The Mirrored world's treasure room will **not** contain a second item.
* More Options will work for Treasure Rooms during the Ascent as long as those rooms were never originally entered.

## Synergies

* / : Both items are copied, allowing Isaac to take both copied items without the other disappearing. The original pedestals will function as normal, disappearing the other if one is collected.
* : Both items can be taken, although they must be paid for with hearts.
* : Entering an unexplored More Options Treasure Room and then using Glowing Hourglass can cause the room's layout to change rerolling the offered items. The reroll is not always guaranteed as Glowing Hourglass is causing the Treasure Room to alternate between a set number of different More Options room layouts on a given floor with repeat layouts offering the same items.
* Jacob and Esau: Both brothers can take one item each if they are lined up properly.
* : Treasure Rooms will always contain a Shop Restock Machine in addition to the two choice items.
	+ In Downpour, Dross, and Mines, Pay to Win by itself can sometimes spawn the combined Treasure Rooms, even without More Options. Having both doesn't guarantee the combined effect.
		- For Ashpit, Mausoleum, Gehenna, and Corpse, this combination does work correctly for normal-sized Treasure Rooms, but not thin ones.

## Trivia

* Prior to *Repentance*, this item's description was "There are even more options!"
* ' description is "More options". For this item, it's the other way around.
Myosotis

## Effects

* Spawns pickups left on the previous floor in the starting room of the current floor.
	+ A maximum of 4 pickups can be spawned.

## Notes

* The "previous floor" status of trinkets can be reset by picking them up and dropping them again, allowing multiple other trinkets to be carried between floors.
* Trinkets that were left in the Treasure or Boss Room still transform into a  during the Ascent, potentially allowing you to gain large amounts of Cracked Keys.
* Spawns pickups on the first floor if  was used.
* Does not bring pickups from error rooms.

## Trivia

* Forget me not is a common name for the flower genus Myosotis.
* This trinket originated in *Antibirth*. It was originally capped at 8 pickups instead of 4.
Red Candle

### Unlock Method

 Donate 400 Coins to the Donation Machine

**Red Candle** is an unlockable activated item.

## Effects

* On use, Isaac raises the candle above his head. On pressing a fire button, a red flame, similar to a Red Fire Place, will fire in the chosen direction. It can pass over pits, but can not travel through obstacles.
	+ The flame deals 23 damage per tick, and can hit up to 5 times for a maximum of 115 damage per flame.
	+ The flame can hit up to 4 times, and the damage decreases as the flame shrinks. The first hit deals 23 damage, the second hit deals 17.5 damage, and the last two ticks deal 11.5 damage, for a maximum of 63.25 damage per flame.
	+ The flame also destroys enemy shots it comes into contact with, which decreases its size each time being hit until the flame is entirely extinguished by this process.
	+ The flame projectile is persistent and will remain active in the room until it deals a set amount of damage.
	+ Flames will disappear automatically after 10 seconds.

## Notes

* While Isaac holds the candle above his head, his movement speed is reduced.
* There is no limit to the number of fires that can be active. This is useful in situations where mob spawning can be controlled: for example, beating Boss Rush or Greed Mode as  The Lost. This is time-consuming but can be viable if other sources of damage are weak or unreliable.
* It will block Isaac's tears but won't burn him. Isaac's tears can also shrink the size of the flame.
* Flames do not block Isaac's shots, nor are they put out by them.
* Flames will destroy Shopkeepers.
* Flames will turn certain enemies (such as Hoppers and Clotties) into their flaming variants, making them stronger. The flame is unable to damage these monsters.

## Synergies

* : Spawns red wisps in the middle ring. The wisps shoot small flames instead of tears, with a very high tear delay; flames last for 5 seconds or until they block 2 shots and/or deal 2 ticks of damage. The wisps do not persist between rooms, and the damage they deal does not increase with  or scale up on later floors.

## Interactions

* : No effect.
* : When the fire hits the tear, the tear resets and appears again on the player.

## Gallery

* Red Candle The icon of Red Candle as seen on the lower 3DS screen

## Trivia

* The Legend of Zelda, a major inspiration for *The Binding of Isaac*, also has a red candle item that can be activated to create flames for burning enemies and bushes, as well as lighting dark rooms. Unlike in Isaac however, where the red candle is unlocked first, the blue candle is the inferior version of the red one, which can be activated only once per room.
* is a variation of this item unlocked after donating 900 coins, diminishing over time as opposed to contact.
* The pickup quote of this item is a reference to the catchphrase of the Human Torch, a member of the Marvel Comics Fantastic Four.
* This item can be found as one of the Nintendo-themed Treasure Room items in the 6th of December's Daily Run, which is an homage to the late CEO of Nintendo, Satoru Iwata.
Pin

Double Trouble

(with another Pin,  Mega Fatty, Larry Jr., Chub or Blighted Ovum)
Degraded Boss

 *For the item with a similar name, see Safety Pin. For the trinket with a similar name, see Push Pin.*

**Pin** is a boss that can appear in the Cellar.

## Behavior

Pin burrows into the ground before performing the following attacks:

* Jumps out of the ground towards Isaac and burrowing back into the ground at the end of the jump.
	+ Occasionally fires 4 projectiles diagonally from the last section of its body when exiting the ground and/or when burrowing back into the ground.
	+ Fires 4 projectiles diagonally depending on the length of its jump: does not fire projectiles on short jumps, fires projectiles shortly upon exiting the jump on regular/medium jumps, and fires projectiles both shortly upon exiting and after a few moments airborne on long jumps.
* Partially emerges out of the ground to fire a red  shot at Isaac before returning underground.
	+ After performing this attack, Pin will always jump out of the same spot it entered.

## Champion Versions

 **Grey**: 15% larger with 25% more HP. Fires a radial burst of 6 spiraling projectiles instead of an explosive projectile and fires 6 projectiles instead of 4 when jumping.
## Gallery

* Pin in-game.
* Grey Champion Pin.
* Pin as one of  Delirium's forms.
* Concept art of a scrapped boss named "Pin, Trio," along with Mega Maw and what appears to be The Gate.

## Notes

* Each segment of Pin can be individually damaged, so a single piercing tear could hit Pin multiple times.
	+ Moreover, if Pin is petrified (due to  or , e.t.c), his individual segments can even be destroyed (though that would not necessarily deal higher damage), which will shorten the boss in its length.
	+ Piercing shots no longer damage segmented enemies multiple times per attack.
* Despite looking like it's flying above the ground, Pin is not immune to ground-based effects such as creep when doing its jumping attack. On the contrary, every segment is guaranteed to pass over the damaging area, making it more susceptible to damage.
	+ Due to this, Pin also cannot jump across gaps, and will bounce backwards when attempting to cross one.
* The segment that shoots bullets during mid-jump will continue to do so if it's suspended in mid-air with something like .

## Trivia

* Pin was added in the *Wrath of the Lamb* DLC for the original *The Binding of Isaac*.
* The Frail is its posthumous version.
* Prior to Repentance, Pin's Champion version could never appear in-game despite existing in the original *The Binding of Isaac*.
* Pin is based off the pinworm, an internal parasite.
* Pin is likely a reference to Lanmola, a boss from *The Legend of Zelda: A Link to the Past*, as nearly all of their attacks are the same.
* It is the boss version of the  Needles.
* Pin is the only boss that got a new champion variant in Repentance.
Pestilence

Degraded Boss
Main path

Alternate path

**Pestilence** is a Harbinger that can appear in all environments of Chapter 2 (Caves, Catacombs, Flooded Caves).

## Behavior

### Phase 1

* Floats around the room, leaving a large trail of damaging Green Creep.
* Fires an  projectile at Isaac, which leaves Green Creep on impact.
* Summons two Chargers or Spitties and can have a maximum of four summons.
	+ Any Chargers or Spitties caught in Pestilence's Ipecac explosion will be killed.

### Phase 2

After taking enough damage, Pestilence's head will explode, beginning the second phase.

* No longer moves around the room but slowly drifts around, leaving Green Creep.
* Continues to fire Ipecac projectiles at Isaac, but at a faster rate.
* Summons two Attack Flies.

Pestilence deals a whole heart of contact damage in both phases, though without flight Isaac is more likely to be damaged by the Green Creep instead.

## Champion Versions

**Grey**: Leaves a trail of slowing White Creep instead of Green Creep, shoots 6 projectiles in all directions instead of an Ipecac shot and spawns Trites instead of Chargers or Spitties. He cannot spawn more than 3 Trites at once. It spawns Spiders instead of Attack Flies in Phase 2.

## Unlockable achievements

* The Book of Revelations - Defeat a Harbinger.

* 7 Seals - Defeat all 5 Harbingers.

## Trivia

* Pestilence appeared in the original *The Binding of Isaac*.
* Pestilence is not directly one of the Four Horsemen of the Apocalypse and is not present with the other Horsemen in Revelations (Revelation 6:2). The canonical Four Horsemen are Conquest (white), War (red), Famine (black), and Death (pale).
	+ However, pestilence is featured as one of God's "four disastrous acts of judgment" alongside sword, famine, and wild beasts (Ezekiel 14:21), which, in some cases, can be interpreted as symbolic of the Horsemen- as the acts of judgement are often used by God for destructive purposes throughout the Bible.
		- These four acts are given to the Horseman of Death to perform (Revelation 6:8) despite the contradictory fact that famine, the attribute of a completely separate Horsemen is among the acts.
	+ Despite not being a true Horseman,  Ultra Pestilence still appears instead of an ultra version of Conquest during  The Beast fight.
* Pestilence means a fatal disease epidemic.
* Pestilence is the only Harbinger that does not have a charge attack.
* Pestilence’s head resembles The Husk.
* Pestilence makes a "Hey!" sound when launching explosive projectiles at Isaac. Famine makes the same noises when spitting shots at Isaac at its second phase.
Polydactyly

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

## Effects

* Allows Isaac to carry two cards, pills, or any combination of both.
* Spawns one random card, rune, or pill.

## Interactions

* : No additional effect.

## Trivia

* Polydactyly is a birth defect affecting people born with extra amounts of fingers or toes than is normal.
Portable Slot

**Portable Slot** is an activated item.

## Effects

* Upon use, consumes 1 Penny and has a chance to drop a random pickup, like a Slot Machine.
	+ Unlike a Slot Machine, the default reaction to using a bad Pill will occur if the Portable Slot grants nothing.

**Possible Results from Coin Gamble (in Percentage % Points)**

Penny (Disambiguation)

**Penny** may refer to:

## Items

* : Can either duplicate all items and pickups in a room, or make all of them disappear and spawn 1 coin.
* : A bag familiar which follows Isaac and drops a Coin every two rooms.

## Trinkets

* : Has a chance to spawn a half Soul Heart when a coin is picked up.
* : Grants 50% chance to drop a half Red Heart when a coin is picked up.
* : Grants 50% chance to drop a Bomb when a coin is picked up.
* : Causes Isaac to fart upon picking up a coin, knocking back nearby enemies.
* : Has a chance to charge an active item when a coin is picked up.
* : Upon picking up a coin, has a chance of increasing its value by one.
* : Teleports Isaac to a random room when a coin is picked up.

Pitch Black

**Pitch Black** is challenge #1. During this challenge, Curse of Darkness and Curse of the Unknown will be permanently active. Unlike other challenges, Treasure Rooms are available, but Shops are not. The goal is to defeat Mom. This challenge is unlocked by default.

## Difficulty

The curses inflicted are typically trivial on their own, however, they are the primary source of difficulty in this challenge due to the permanence of Curse of the Unknown, making it much more difficult to keep track of Isaac's health. This also makes it especially risky when using mechanics that drain Isaac's health, such as devil deals or Blood Donation Machines. Additionally, Curse of Darkness, although mostly just thematic, does contribute to the difficulty of the challenge by making it harder to spot tinted rocks, which normally would aid Isaac's survival with Soul Hearts. As well as this,  doesn't clear any of the curses in this challenge.

## Strategy

While Devil deals can provide powerful items, taking one is very risky unless Isaac's health is carefully tracked. Refraining from deals can give access to Angel Rooms, which can provide items without the need to sacrifice health.

Turning the gamma setting up in the options can lessen the impact of Curse of Darkness.

While entering one is not recommended, finding a door to a Boss Challenge Room can at least gauge Isaac's health by checking whether it's open or closed.

Amnesia pills don't incur the Curse of the Lost, thus being one less bad pill to worry about; with  an amnesia pill will also drop Black Heart on use for free.

## Unlockable achievements

* Rune of Hagalaz - Complete **Pitch Black (challenge #1)**.
Restock

### Collection Grid

*(page 4, column 11, row 1)**(page 4, column 11, row 1)**(page 4, column 12, row 1)*

**Restock** is a passive item added in *The Binding of Isaac: Afterbirth*. All characters start with **Restock** in Greed mode.

## Effects

* Upon purchasing an item from the Shop, a new purchasable item is added to the store's inventory.
	+ Collectibles created correspond to the shop's item pool.
* Drops 3 random pickups around Isaac.
* Outside of Greed Mode, the restocked item's cost is increased after each purchase.
	+ For items, the price increase is 2 coins times the number of purchases. For example, an item starting at 15 cents would next be +2 to 17, then +4 to 21, +6 to 27, etc. The cost follows the formula 15+n(n+1) with n being the number of times restock has triggered.
	+ For everything else, the price increase is 1 coin times the number of purchases. For example, a heart starting at 3 cents would be +1 to 4, +2 to 6, +3 to 9 etc. This follows the formula (original price)+(n(n+1))/2
	+ The increase is not affected by discounts occurring naturally or through : costs will increase at the same rate, though the base price is still discounted. Once the item's cost goes over what it would naturally be, the price is no longer highlighted red.
	+ The maximum price is 99 cents.
* A small restock icon appears under the map, just like , ,   and any active curses.

## Notes

* If used with /Blood Donation Machine and an item which can spawn additional coins (, , , etc.), infinite money can be produced by buying hearts for 3 coins and getting more than 3 coins back after donating health.
* Using a  in a Shop prevents Restock from working for that shop only.
	+ A Shop Restock Machine will refresh the items, which Restock will interact with normally.
* When purchasing Restock from a Shop, the slot that Restock was purchased from will not be restocked.
* Restock does not affect Black Markets or purchasable items generated via  or .
* Purchasing an item that is on sale will replace it with another that is on sale.

## Synergies

* x2: Items can be infinitely bought from shops.
* + :  If a Lil' Battery is on sale, items can be bought infinitely.
	+ If a Lil' Battery is on sale, Isaac can buy a lot of items before the prices become too high in that shop.
* : Restock is affected by Chaos, and can be used to obtain otherwise rare items.
	+ **Chaos** +  x2: Items can be bought infinitely, allowing Isaac to theoretically obtain every item in the game.
* : Buying spawned pickups in the Shop will always respawn them as items and their prices will never increase. This does not work outside of the shop.
* : Items bought in the separate shop will also be restocked.

## Interactions

* : Items made free by Coupon will not be restocked, even while playing Greed Mode.
* : Items stolen by Mr. ME! will be not restocked, even while playing Greed Mode.
R Key

**R Key** is an activated item added in *The Binding of Isaac: Repentance*.

## Effects

* Returns Isaac to the beginning of the run in Chapter 1, with all stat boosts, items, pickups, and trinkets intact, similar to a Victory Lap. Unlike a Victory Lap, however, no effects are applied after a certain number of uses, and the timer is not reset.

## Notes

* Angel Rooms once again become possible to appear even if the player has made a previous devil deal.
* The chance for a Planetarium to appear can once again be increased above 1% without a , even if the player has previously entered a Planetarium.
* If the Donation Machine was jammed before usage, it will no longer be jammed.
* True Co-Op players can be spawned in at the first room after using the R Key.
* If used in a run while achievements and character unlocks are enabled, they will still be enabled after use. Similarly, if these are disabled because the player is in a Victory Lap or seeded run, they will remain disabled after use.
	+ Beware that using R Key during a Victory Lap will reset the lap counter to 0, as though every Victory Lap is considered part of the same run. Shops will appear as normal, and no items will be removed upon starting the next lap. However, the character will remain  The Lost if it had been changed, and the game will remain on Hard difficulty.
* The timer and score do *not* reset.
	+ This means that the timer requirements to access Boss Rush, ???, and  do NOT reset.
* Item pools are *not* reset. This means that another R Key can't spawn (and neither can any other items that were already encountered).
* The 13 pill pool does *not* reset, unlike with a victory lap.
* and  may also be obtained again, even if already consumed in the Chest or Dark Room to unlock Mega Satan's door.
* and  may also be obtained again.
* In scenarios where R Key can be purchased, it uniquely costs 99 coins instead of 15.
	+ This rule does not apply to the extra shop created by .
	+ This rule also does not apply to devil deals spawned by .
	+ Despite this, using  on R Key will still only spawn 15 coins.
* In Greed mode, using the item after breaking the Greed Donation Machine will fix the machine, while also preserving the coin total the machine had before breaking.
* While difficult, it is possible to use R Key while swapping it out with another active, letting you bring a different active item to the beginning of the run.
* R Key cannot be obtained in the Daily Challenge.
	+ This includes through use of a .

## Interactions

* : No effect.
* : Using R Key during the Ascent sequence will end it.

## Gallery

* Concepts for 3 items that were originally implemented in *Antibirth* and later *Repentance*, including R Key.

## Trivia

* R Key originates from the *Antibirth* mod.
* This item is a reference to how holding down the R key on PC will restart a run.
* This item is very similar to Clone from *Enter the Gungeon*. The only difference is that R Key is an activated item while Clone is a passive item that activates upon death.
Mr. Dolly

### Collection Grid

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

* +5.25 range.
* +2.5 range.
* +0.5 tear falling speed.
* Spawns a combination of 3 Red Hearts, Soul Hearts or Black Hearts on the floor when picked up.
	+ These hearts are not subject to the Red/Soul/Black Heart chances; each type has an equal chance to spawn.

## Trivia

* This item is part of a set of bedtime-themed items, including , , , and .
* The doll resembles a small  Magdalene.
* It is refered as "Mr." despite looking conventionally female with long blonde hair and a bow.
Paschal Candle

**Paschal Candle** is a passive item added in *The Binding of Isaac: Repentance*.

## Effects

* Gives Isaac a candle familiar that grants a Fire Rate bonus of +0.4 for each room cleared in a row without taking damage, which stacks up to 5 times (Max. +2 Fire Rate), represented by how brightly the flame burns. Starts at 1 stack, and resets to zero if damage is taken.

## Notes

* The Fire Rate bonus can exceed the normal Fire Rate cap.
	+ Any self-damage, such as from Curse Rooms, Sacrifice Rooms, the Bad Trip pill, spiked chests, and self-damaging items such as , won't reset the bonus.
* Clearing waves in Greed Mode will give the candle charges as if you cleared rooms.
* Familiars that follow behind Isaac have a certain priority in how close their position is to him over other familiars, with Paschal Candle having the lowest priority at 6th and thus being farther from Isaac than familiars of different priorities.

## Synergies

* / any similar item: The flame is not snuffed out when damage is negated by the shield.

## Interactions

* : The candle appears larger, but otherwise does not change.
* : No extra familiars or stat boosts are granted from copies.

## Trivia

Pitfall

**Pitfalls** are invulnerable and stationary enemies which Isaac can walk over. When Isaac walks over a pitfall, he falls in, takes damage, and pops back out after a short delay. Pitfalls disappear after falling into them. They are only spawned by several of Little Horn's attacks.

## Variations

### Found In

**Suction Pitfalls** act as regular pitfalls, but suck Isaac in like a Gaping Maw. They are typically found in rooms with Pressure Plates, which when pressed will make any Suction Pitfalls in the room disappear.

### Found In

Only spawned by Little Horn.

**Teleport Pitfalls** act as regular pitfalls, but pop Isaac out at a random location after damaging him. Little Horn spawns these and pushes them outward in some of his attacks.
