## Trivia

* 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.

* : Broken Modem also affects friendly chargers.
* : Erasing a Charger will prevent all newly created friendly Chargers from spawning as the item spawns a normal Charger before changing it to the special My Shadow variant.

Smart Fly

### Collection Grid

*(page 3, column 9, row 6)**(page 3, column 19, row 1)**(page 3, column 20, row 1)*

**Smart Fly** is a passive item.

## Effect

* Spawns a fly familiar whose behavior changes depending on whether or not Isaac has taken damage in the current room.

	+ Before Isaac takes damage, the fly serves as an orbital, blocking enemy shots.
	+ After Isaac takes damage, this fly will seek out nearby enemies and attack them.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a giant humanoid fly.

## Notes

* Smart Fly does not take up one of the three orbital slots; it floats between two of the other orbitals.
* While behaving like an orbital, Smart Fly will break away from Isaac if he is traveling fast enough and will follow Isaac until he slows down enough to reattach. This is the only orbital item in the game that exhibits such behavior.

## Interactions

* : Fly will stay in place when orbiting Isaac but will still pursue enemies.
Sharp Plug

**Sharp Plug** is a passive item.

## Effects

* Damages Isaac in exchange for fully recharging Isaac's current activated item.
	+ Sharp Plug costs two hearts of health to use.
		- Sharp Plug's heart cost is one half-heart per charge slot filled. The health cost is not increased in later stages where half-heart damage is upgraded to full heart.

## Notes

* If Isaac has less than two Black or Soul Hearts, it will remove them but will not remove any Red Hearts.
* Sharp Plug attempts to draw from Red Hearts first.
* Sharp Plug cannot deal fatal damage. If used at half a heart, it will not work.

## Synergies

* Damage-triggered items: Each half heart used up by activating Sharp Plug triggers damage effects separately, allowing multiple payouts.
	+ Expends health for charges at the rate of 2 charges per 1 Coin Heart. If an item is 1-charge, removes 1 Coin Heart.
* : As long as Isaac has more than 2 full hearts, time can be rewinded indefinitely since the health used to recharge the item is refunded upon use.
* Keeper: The Keeper takes only one heart of damage.
* : The active item in the main slot is fully charged as normal and the secondary slot gains as many charges as the main one did.
* Tainted Magdalene: Tainted Magdalene's  can be used infinitely, allowing for infinite invincibility frames from taking damage. Paired with Tainted Magdalene's melee attack, this can easily win a run.
* : Reduces the health cost to half a heart (except for Keeper).

## Interactions

* : Renders the Sharp Plug unusable. Sharp Plug can only be used if the item is at 0 charges, but 9 Volt instantly gives 1 charge to the item upon activation.
	+ As Sharp Plug can now be used with charges and the cost is based on charges filled, 9 Volt now synergizes with Sharp Plug, lowering the cost of using it by half a heart on 2+ charge items.
* : Expends up to 6 full hearts if possible with no charges given.
* Bethany /  Tainted Bethany: Soul/blood charges are used before Sharp Plug when available.
* : Attempting to recharge the Eraser with the Sharp Plug fails and only hurts Isaac for half a heart.
* : Holy Mantle blocks the damage from Sharp Plug if the shield is active, but also keeps Isaac's active item from charging.
	+ Bypasses the Holy Mantle and gives charges as usual.
* : Renders the Sharp Plug unusable.
* The Lost: No benefit from this item unless he has a respawn item because his active item's charge will not refill if the  effect activates. Sharp Plug only activates upon receiving actual damage.
	+ No effect, as The Lost doesn't have health.
	+ Tainted Jacob or White Fire Place Lost form: Activating Sharp Plug will take the health cost from the original character's health.  will not block the health cost.
		- **Lost form** + : Every point of health taken to activate Sharp Plug is considered fatal damage, leaving Isaac with as little as half a soul heart. It is possible to get 12 Broken Hearts in addition to this final half heart, past the normal limit.
* : Sharp Plug will not work with Mega Blast.
	+ Works as intended, giving 1 charge per half a heart.
Sack of Sacks

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

## Effects

## Synergies

* : The drop rate is improved to every 4-5 rooms.
	+ The drop rate is improved to every 6 rooms.

### Unlock Method

 Complete the Boss Rush as  Samson

**Samson's Chains** is an unlockable passive item.

## Effects

* Attaches a ball and chain to Isaac's ankle that blocks projectiles and deals 5 damage per tick (~10.7 damage per second).
* If the ball is moving fast enough, it will destroy any Obstacles it comes into contact with (aside from Iron Blocks).

## Notes

* The item doesn't change the Speed Attribute. Instead, whenever the chain is fully extended the ball will have to be dragged, which causes Isaac to slow down slightly.
* Cannot be used to open Secret Rooms or Super Secret Rooms.
* CAN be used to initiate the Uriel/Gabriel fight inside Angel Rooms.

## Synergies

* Flight: Any method of flight makes it easier and quicker to use Samson's Chains to smash rocks, making for an efficient way to search for Crawl Spaces.

## Trivia

* This item references the biblical story of Samson, who was chained upon losing his strength.
* This item is also likely a reference to the *Spelunky* ball and chain, which also slows the user, destroys blocks, and can be used against enemies.
Stage HP

**Stage HP** is a feature of some enemies, granting them extra health the higher the stage number they're encountered in is.

{\displaystyle \color{white}\mathit{HP} = \mathit{Base HP} + \left(\mathrm{min}(4, \mathit{Stage}) + 0.8 \times \mathrm{bound}(0, \mathit{Stage} - 5, 5)\right) \times \mathit{Stage HP},}

where *Base HP* and *Stage HP* are the defined HP values for the given enemy and displayed in the enemies' pages, *Stage* is the current stage number as defined internally by the game and *min* and *bound* are functions that take the smaller of two values or bound the middle value between the two others respectively.
In practice, this means the enemy gains *Stage HP* extra health for the first 4 stages, gains nothing for stage 5, and then 4/5ths of *Stage HP* up to stage 10 after which their health stops increasing.

Chapters map to stage numbers as follows:

### Example

Consider a Dip with 3 base HP and 1 stage HP.

* Basement I, i.e. stage 1: HP = 3 + (min(4, 1) + 0.8 \* bound(0, 1 - 5, 5)) \* 1 = 3 + (1 + 0.8 \* 0) \* 1 = **4**
* Womb II, i.e. stage 8: HP = 3 + (min(4, 8) + 0.8 \* bound(0, 8 - 5, 5)) \* 1 = 3 + (4 + 0.8 \* 3) \* 1 = **9.4**
* The Void, i.e. stage 12: HP = 3 + (min(4, 12) + 0.8 \* bound(0, 12 - 5, 5)) \* 1 = 3 + (4 + 0.8 \* 5) \* 1 = **11**

## Monsters and Bosses that use Stage HP

A total of 52 Monsters and 18 Bosses use this mechanic, with the Sins counted among the latter group.

## Trivia

* The Wizoob and Red Ghost are the only entities whose Stage HP were reduced in Repentance, both from 5 to 4.
* The Monster with the lowest Stage HP (and with the lowest amount among all entities) is the Swarm Spider at 0.2, while the Monster with the highest is the Holy Bony with a staggering 14, nearly twice the amount of 2nd place. All other Monsters have an amount between 1 and 8.
* The Boss with the highest Stage HP (and with the highest amount among all entities) is a tie between Krampus and The Fallen at 45. All other Bosses have an amount between 7.5 and 30.

## Trivia

* A "speedball" is cocaine or an amphetamine mixed with heroin or morphine.
* The G FUEL! item that appears with the special GFVE LLLL easter egg seed or during daily runs with the same effect enabled is considered a "temporary" version of Speed Ball with a replaced sprite, different costume and additional effects. Normal Speed Ball is still available, however.

* The flat damage gained by Sacred Heart is not affected by its damage multiplier. However, other flat damage upgrades (such as those gained by  or ) will be affected normally.
* Although Sacred Heart increases range, the reduction of shot speed results in a slight decrease in effective range, not accounting for homing.

## Interactions

* : Tears will track enemies while frozen in place, once one gets close enough.

Singe

**Singe** is a boss added in *The Binding of Isaac: Repentance* that can appear in the Ashpit.

## Behavior

Singe always spawns with 4 damaging spiked rock balls that can be pushed around; these play an important role in his attacks. Any spiked rock caught up in an explosion launches rapidly across the room, bouncing when colliding into obstacles, walls, and each other.

* Farts, leaving a cloud of explosive gas.
	+ Spiked rocks caught in this attack will be propelled slowly.
* Runs erratically towards Isaac or a spiked rock and creates an explosion at the end of the run.
	+ If close to Isaac at the end of the run, Singe can also perform a short jump in Isaac's direction to gain extra distance, creating an explosion on landing.
* Charges up before releasing a large explosion, launching Singe into the air and creating a small cross-shaped pit in his wake; after a few moments he lands on top of Isaac's position. This attack spawns an additional spiked rock that lands down alongside him. This attack only occurs twice during the fight and only after Singe has reached a certain amount of HP.
	+ Spiked rocks are able to be launched into the pit that Singe creates. This temporarily removes it until Singe generates another explosion which spawns it again from the ceiling.
	+ Multiple spiked rocks can be removed at a time but Singe only spawns one back at a time per each explosion.
* After performing his second large explosion, Singe gains a new attack where he lights a match and places it in front of his butt, farting to produce a large stream of fire that follows Isaac's movement.
* Singe's explosion upon death can also damage Isaac.

## Trivia

* A singe is a superficial burn.
* Along with The Beast, this is Edmund's favorite boss in Repentance.
* According to a Twitter AMA on April 4th 2021, the reason why Singe is so gassy is because he "eats farts". Why this is remains a mystery.
* The bestiary features a unique dancing animation that doesn't play during Singe's fight.
	+ The animation is referred to as "yeehaw" in the .anm2 file.
* Singe's matchstick attack is a possible reference to the Pyro's Gas Blast taunt in *Team Fortress 2*.
Steven

Degraded Boss

This article is about the boss. For the damage item, see Steven (Item). For the familiar item, see Little Steven.
**Steven** is a boss that can appear:

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

Each Steven has 140 HP.

## Behavior

**Phase 1**

* Big Steven chases Isaac and periodically charges increasing its speed, but stopping to catch his breath afterwards.
* Steven Baby shoots a projectile towards Isaac if not behind an obstacle.

**Phase 2**
If Big Steven reaches 50% HP, they separate:

* Big Steven continues the same patterns.
* Steven Baby begins charging furiously at Isaac.
* Both, when killed shoot out projectiles in all directions.
	+ 8 projectiles each.
	+ Big Steven: Two rows of 8 slow-moving projectiles that travel over obstacles and off-screen which also deal a whole heart of damage. Small Steven: unchanged.

Small Steven can be targeted and killed first with no change to either Steven's behavior.

## Gallery

* Big Steven in-game.
* Little Steven in-game.
* Steven as one of  Delirium's forms.
* Big Steven in-game before *Repentance*.
* Little Steven in-game before *Repentance*.
* Steven as one of Delirium's forms before *Repentance*.

## Notes

* Steven is much less common than his counterpart, spawning only 1/4th as often.
* Steven's arena will always look the same as Gemini's.

## Trivia

* Steven appeared in the original *Binding of Isaac*.
* He is a rare alternative to **Gemini**.
* Steven originated from the 2009 flash game *Time Fcuk*, which was created by Edmund McMillen.
* Steven can appear in Greed Mode prior to his prerequisites being completed.
* As they appear in *Time Fcuk* and on the boss art, Big Steven and Steven Baby have the back of their heads attached. However, their attachment does not appear this way in-game. This is likely due to Big and Small Steven having the same function of how Contusion and Suture are conjoined, only without the long cord holding them together.
* According to Edmund McMillen, Steven is connected to Isaac.
* Steven also appears in *The End is Nigh*, another game created by Edmund McMillen.
* One of the images that can appear before the start of a new run states: "GET IN THE BOX", which is Steven's unofficial catchphrase from *Time Fcuk*.
	+ It is also likely an allusion to both *Time Fcuk* and *The Binding Of Isaac* taking place inside some form of box.
* Big Steven's appearance as one of Delirium's forms shares the appearance of Ash, the main protagonist of *The End is Nigh*.
* Steven Baby's projectiles have a completely unique visual design while Big Steven's death projectiles have both unique visuals and behaviour.
	+ These new designs were made to coincide with Edmund's project *Øuroboros*, which also features Steven; teased in 2016.
* In the Bestiary, Little Steven is referred to as "Steven Baby".

	+ Furthermore, Edmund confirmed that Bob is Isaac’s father’s brother, which makes Bob Isaac’s uncle.
		- This may possibly be just a joke based on the phrase "Bob's your uncle".
* Sloth's sprite is just a re-coloring of the Globin enemy. This may have been done humorously to match his sin, Sloth (laziness).
* 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.
* Sloth is a personification of one of the Seven Deadly Sins. Sloth is an excessive aversion towards difficulty in regards towards doing good, or moral/spiritual laziness. It is believed to lead to negligence, idleness, spite towards those who do good, despair, and other capital sins such as gluttony and lust.

Scarred Womb

*(chapter 4)*

The **Scarred Womb** is one of the environments in Chapter 4 added in *Afterbirth*. The theme of the Scarred Womb is wounded and scarred tissue, grafted skin, and early stages of decay. The floor looks much like a failed surgery, with stapled skin being plastered onto the womb's walls being this floor's alt. backdrop. Most new enemies featured in The Scarred Womb are damaged and grievously injured variations of other enemies. Rocks have a chance to be replaced with Red Poop.

The Scarred Womb's alternate floors are the Womb and the Utero.

 The Scarred Womb is unlocked by defeating It Lives 30 times.

* Killing  Dogma and  The Beast also increases this tally, as does Mausoleum's version of Mom's Heart.

## Monsters

* Gluttony
* Lust
* Sloth
* Wrath
* Blastocyst (small and medium)
* Chub
* Dingle
* The Duke of Flies
* Fistula (all sizes)
* Gemini
* Gurdy Jr.
* Gurglings
* The Haunt
* The Hollow
* Larry Jr.
* Loki
* Mega Fatty
* Mega Maw
* Monstro
* Peep
* Pin
* Polycephalus
* Widow
* The Wretched

## Bosses

### Final Boss

It Lives will always appear in the second floor of this chapter or in the last boss room if the Curse of the Labyrinth is active.

After being killed 11 times, Mom's Heart is permanently replaced by It Lives.

## Unlockable Achievements

* Eden - Complete Chapter 4.

* Pop! - Beat Chapter 4 without taking damage.

* Mama's Boy - Beat Chapter 4 without taking damage.

## Trivia

* Before the proper release of *Afterbirth*, the Scarred Womb was to be named "Rotten Womb".
* The stitches on the walls and floor faintly resemble the Fistula boss.
* Using  on the scarred womb will flood the room with red liquid (likely blood) instead of water.
* Previously, Mom's Heart could appear in the Scarred Womb. However, as of Booster Pack #5, since it is required to defeat It Lives 30 times to unlock the Scarred Womb, Mom's Heart can no longer appear in it.
	+ However, since defeating  Dogma and  The Beast add to the count, it is technically possible to encounter Mom's Heart here a grand total of once, as 10 Mom's Heart kills unlock Hush, 11 kills unlock It Lives, and Hush is required to be beaten at least three times to unlock Dogma and the Beast.

## Music

* The music for the Scarred Womb is titled *Cicatrix*.
* A cicatrix is a medical term for a scar, as well as the Latin term for "scar".
* The music heard during the fight against Mom's Heart/It Lives is called *Ventricide*. Ventricide combines ventricle, a word that means a hollow area in an organ and is often associated with the heart, and the suffix -cide, which denotes the act of killing.
	+ This has been confirmed by Edmund when he said it means something like "the killing of the heart". This is in theme with other similar boss tracks such as Matricide, Hericide, and Infanticide.[*citation needed*]
Sack of Pennies

**Sack of Pennies** is an unlockable passive item.

## Effect

* Spawns a familiar that drops a coin every 2 rooms.
	+ The first drop happens after 1 room.

## Notes

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

## Synergies

* : The familiar drops coins in a repeating pattern of 1, 2, 2 then 2 rooms.

## Trivia

* This item is used in  PAY TO PLAY (challenge #24).
* This item is the coin counterpart to , , , and .
Super Ball

**Super Ball** is a trinket added in *The Binding of Isaac: Afterbirth †*.

## Effect

* Adds a chance to fire tears that bounce off of enemies and obstacles.

## Notes

* Super Ball's tear effect functions identically to . For a full list of interactions and synergies, see that page.

## Trivia

* A Super Ball is a type of toy ball that is known for its extreme bounciness. Dropping it onto a hard surface will cause it to bounce nearly to the point it was dropped.
Rosary

**Rosary** is a passive item.

## Effects

* Grants 3 Soul Hearts.
* is added to all item pools.
* +0.5 tears.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into an angel.

## Notes

* If The Bible has been picked up before collecting the Rosary, it will not be re-added to item pools.
* The Bible can be encountered multiple times even in the same pool if it is not picked up; however, once picked up, it cannot appear again anywhere.
* This item stacks with , further increasing the chance to find The Bible in the Library and Shop.
* The approximate chances of finding  in each item pool are:
	+ Treasure Room: 2.26%
	+ Shop: 12.82%
	+ Boss: 11.36%
	+ Devil Room: 12.82%
	+ Angel Room: 20.83%
	+ Secret Room: 20.83%
	+ Library: 45.45%
	+ Golden Chest: 55.56%
	+ Red Chest: 71.43%
	+ Beggar: 27.78%
	+ Devil Beggar: 45.45%
	+ Curse Room: 38.46%
	+ Key Master: 71.43%
		- The probabilities after Rebirth are unknown, though the chances are pretty similar to the ones shown above. This is because the smaller the item pool, the more likely the Bible is to appear, and this effect is far more pronounced than the Bible simply being added to each pool. So, for example, the Bible is much more likely to appear from a Red Chest compared to the Treasure Room.

## Trivia

* Prior to *Repentance*, Rosary's description was simply "Faith up".

### Passive Collectibles

Seven Deadly Sins

The **Seven Deadly Sins** are mini-bosses that can be encountered on any floor in their respective Mini-Boss rooms outside of The Chest and Dark Room. Unlike with bosses, there is no special door leading to a mini-boss room, meaning that there is no way to tell whether a room is inhabited by a mini-boss unless the player has an item that reveals map icons such as Compass or a Map item. Once in a mini-boss room, the player cannot escape through means of bombing the door, as it will be boarded off. The Sins and Super Sins notably become tougher the later in the game they are encountered.

Each of the Sins has specific drops, that are consumables or a pedestal item (less frequently). In a room containing multiple Sins, only the last one will drop something, allowing you to choose what drop you want by killing a certain mini-boss last.

All of them are based on the Seven Deadly Sins.

## Super Sins

These are much stronger alternatives to the original sins, known as the Seven Super Deadly Sins.

 The Super Sins cannot appear during Chapter 1.

## Ultra Sins

There is an Ultra variant of both Pride and Greed. Ultra Pride resembles Edmund and Florian, while Ultra Greed and Ultra Greedier serve as the final bosses for Greed Mode and Greedier Mode respectively.

* This item belongs to the  set. Collecting three items from this set will transform Isaac into a three-faced version of himself.

Upon getting three items or pills that increase Isaac's size, he will create dust clouds when walking and have a chance to spawn rock waves around him upon taking damage.

 Isaac can also crush rocks and other destructible obstacles by walking over them. Touching spiked rocks sometimes doesn't deal damage, depending on Isaac's size, speed and angle they're touched from.
