When Life Gives You Lemons

**When Life Gives You Lemons** is Challenge #12. Start off with , ,  and 1 Lemon Party pill. The goal is to defeat Mom. This challenge is available by default. Treasure rooms are not present.

## Difficulty

The lack of Treasure Rooms makes the challenge more difficult than a normal run.

## Strategy

* Lemon Mishap has a small range, making it difficult to use. The Habit and 9 Volt will allow more frequent uses of it but their combination is more important than that. Because every run starts with 9 Volt, any activated item obtained will take less time to recharge. The Habit makes taking damage charge it faster as well. The only catch would be finding a better activated collectible.
* The  is an extremely beneficial trinket in this run, expanding the area of Lemon Mishap and thus making it safer to use since Isaac doesn't need to be as close to the enemy.
* A good item to find is , simply for being usable every room because of 9 Volt.

## Reward

* Card Against Humanity - Complete **When Life Gives You Lemons (challenge #12)**.

## Trivia

* The challenge name is a reference to the proverbial phrase "When life gives you lemons, make lemonade."
* One of the Fortune Telling Machine's fortunes is "When life gives you lemons, reroll!"

* : 25% chance to spawn nothing, 50% chance to spawn one coin, and 25% chance to spawn two coins.
* : When combined with ,  Keeper gets practically infinite money

## Trivia

* Wooden nickels are souvenir coins given out by some American banks. The adage "Don't take any wooden nickels" is a reminder to be cautious in one's dealings, since these coins have no monetary value.
* The Wooden Nickel is the name of the shop in another one of Edmund's games, *The Legend of Bumbo*.

### Links

None

*This was the first retail version of the game.*

## Documented changes

* Some log output removed.
* Bugfixes.
* Will erase any old stats and saved game.

## Trivia

* In the resources/packed file, there is a file titled readme.txt. It reads:

```
You might wonder how you can open those .a files. Currently there are no
tools available, and there is a reason to it.

Binding of Isaac: Rebirth has a lot of content that is unlocked as you
progress. It also contains some secrets.
We felt that having a folder with all the spritesheets, cutscene videos,
data files and whatnot would be too tempting for people to ignore.
Finding out things while playing the game, either alone, with friends,
or as part of an online community can be a very rewarding experience. We
don't want to take that away from you.

In case you like reverse engineering and absolutely want to take this
beautiful game apart, we would ask you a few things.
 - Don't release any secrets you find to the internet.
 - Don't publish information on how to open the game's data files.
 - Don't give away the unpacked resources.
The least you can do is wait until the game has been released for a
couple of months, so you don't accidentally spoil it for others.

If you have any questions, write to isaac@nicalis.com.

```
Your Soul

*For another trinket with a similar name, see Found Soul. For the item with a similar name, see Lost Soul.*
**Your Soul** is an unlockable trinket added in *The Binding of Isaac: Repentance*.

## Effects

* Grants 1 free Devil Deal item in exchange for the trinket.
	+ After a Devil Deal has been taken, the trinket is removed from Isaac's inventory.
	+ Also works in Black Markets and all other places where heart containers can be exchanged for an item.

## Notes

* Your Soul has no effect on Devil Deals that cost money instead of health, such as from , or playing  Keeper and  Tainted Keeper.
* Using Your Soul as  The Lost /  Tainted Lost grants the possibility of taking two items from the Devil Deal instead of only one.
* Using Your Soul still counts as taking a Devil Deal for the purpose of determining Angel Room eligibility.
* Taking multiple deals at the same time with  Jacob and Esau will make both free. The trinket will still be removed.

## Trivia

* The name and mechanics of the trinket refer to "selling your soul", where a person makes a deal between themselves and Satan or a lesser demon.
* The name and description form "Your Soul. Give it to me", which is a possible reference to Undertale, where a certain somebody asks the player to bring the world that they destroyed back in exchange for their soul.
Whipper

They wield long fleshy whip-like tendrils, which they use for a short-range melee attack. They wander around the room in straight lines and charge at Isaac if he lines up with them, during which they open their mouths wide. If Isaac gets too close, they will slash their whips at him, causing damage and deflecting nearby tears. Whippers will also whip at placed Bombs.

In Gehenna, their appearance changes to resemble a bondage suit.

## Snapper

### Stage HP

 35
 0

### Found In

**Snappers** are much more dangerous versions of the Whipper. They possess a much longer, fleshy whip that can extend across the room, at the minor cost of decreased attack width. They behave similarly to normal Whippers in that they'll charge towards Isaac if he's far enough but in their sights (their eyes turn redder to signify such) but will snap their whips at Isaac if he lines up with them at a moderate or close distance. Similar to the Whippers, their appearance resembles a bondage suit in Gehenna.

## Flagellant

### Stage HP

 42
 0

### Found In

**Flagellants** are even more mutilated versions of the Whipper. They wander around the room in straight lines, charging at Isaac relentlessly if he lines up with them. However, they constantly swipe their whips back and forth as they charge, damaging Isaac if he gets caught and deflecting tears much more frequently than regular Whippers. Flagellants are also more aggressive than regular Whippers and will chase Isaac for a while instead of simply charging once.

## Gallery

* A Whipper's appearance in Gehenna.
* A Snapper's appearance in Gehenna.
* Whippers in *Antibirth*.
* Snappers in *Antibirth*.
* Flagellants/Lunatics in *Antibirth*.

## Trivia

* The Flagellant, Snapper, and Whipper first appeared in the *Antibirth* mod.
	+ Flagellant, Snapper, and Whipper's sprites were changed slightly in *Repentance*.
	+ Flagellants were formerly called "Lunatics" in the *Antibirth* mod and could appear in Corpse.
	+ Snapper in *Antibirth* would only appear in Mausoleum.
* The names of the Whipper and Snapper enemies are a joke to the term "whippersnapper", which is the name for a young and inexperienced person who is considered to be presumptuous or overconfident.
V1.06.0185

Credit for parsing the executable binary changes goes to eur0pa.

* Made lots of changes to the `Entity_Tear` class (probably something to do with Lua bindings).
* The graphic for Mimic Chests was updated to have blood on the corner.
* The graphic for Spiked Chests was updated to match the color of Mimic Chests and have blood on the corners.
* Utero:
	+ Changed room 741 (8 Blastocysts and 1 Portal) to only have 4 Blastocyst Small instead of 8 Blastocysts.
	+ Changed room 780 (8 Blastocysts and 1 Portal) to only have 4 Blastocyst Small instead of 8 Blastocysts. (This appears to be a duplicate of room 741 for some reason.)
* Special rooms (Greed mode):
	+ They forgot to include this floor with Afterbirth+, so the entire file is new, but they didn't add any Afterbirth+ content.
	+ Removed 2 rocks from room 3004. (Presumably, this was interfering with enemy spawns.)
	+ Removed 2 rocks from room 4002. (Presumably, this was interfering with enemy spawns.)
* Depths (Greed mode):
	+ Made it so that the spiders no longer spawn in the corners of room 153 (8 Spiders and 6 Death's Heads).
* Womb (Greed mode):
	+ Made room 54 (3 Masks & Hearts) symmetrical and removed a duplicate entity.
* The Shop (Greed mode):
	+ They forgot to include this floor with Afterbirth+, so the entire file is new, but they didn't add any Afterbirth+ content.
	+ Room 240 (4 Masks & Hearts and a Mask of Infamy) was adjusted so that the Hearts do not spawn in the corners of the room.

### Fixes

* Fixed a bug with hallucinations (when the screen turns grey during The Void.
* Fixed a bug on `Level::Init()`.
* Fixed a bug with  and  where it would "forget" the things you captured after returning from a save and quit.
* Fixed the "filter" option (it was broken since the release of Afterbirth+).

### Lua bindings

YO LISTEN!

**YO LISTEN!** is a passive item added in *The Binding of Isaac: Afterbirth †*.

## Effects

* +1 luck.
* Spawns a familiar that sporadically moves around the room.
* Upon entering a room with a Secret Room/Super Secret Room entrance, tinted rock, or a rock with a Crawl Space underneath, it will fly towards it.
	+ If there are multiple secrets, then it will fly from one to the other.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a giant humanoid fly.

## Notes

* The familiar will sometimes hover over a pit, Poop or empty tile, indicating that an unreachable crawl space has been generated there.
	+ Although it might seem intuitive to dig the spot open with  or , their chance of spawning a crawl space is independent and not guaranteed to work.
* An extra crawl space that is added by  won't be identified by the familiar.

## Trivia

* This item is a reference to the fairy Navi in the The Legend of Zelda: Ocarina of Time, who guides the player during the game with the catchphrase, "HEY, LISTEN."
	+ The item name and description both being “Yo listen!” is a joke about how frequently Navi interrupts the player, to the point of annoyance.
* , , , G FUEL! and  are the only **ALL CAPS** items in the game.

## Gallery

* YO LISTEN's appearance in Booster Pack 5 (left) vs. its original Afterbirth+ sprite (right).
War

Degraded Boss

**War** is a Harbinger that can appear in all environments of Chapter 3 (Depths, Necropolis, Dank Depths).

## Behavior

### Phase 1

	+ He performs this attack more often if Isaac is to his left or right.
* Shoots eight projectiles in all directions.

## Trivia

* War appeared in the original *The Binding of Isaac.*
* War is one of the Four Horsemen of the Apocalypse mentioned in the Bible.
* In many depictions of War, he is shown holding a sword vertically, corresponding with why War's battle sprite shows him holding his hobby-horse vertically.
* Although his appearance on the vs screen shows his hobby-horse as brown, it is red in-game.
* War's "horse" appears more akin to a bull.
* In the original game, War's face was round.

* War can be seen wielding a  as a weapon in one of the original game's concept arts.

Wire Coat Hanger

**Wire Coat Hanger** is an unlockable passive item.

## Trivia

* In his first post-Repentance Lore Stream, Edmund McMillen revealed that the Wire Coat Hanger was a reference to the famous line *"No wire hangers, ever!"* from the 1981 film *Mommie Dearest*, as well as being a reference to a highly dangerous method of self-induced abortion in which a pregnant woman attempts to use a long implement (usually metal) such as a wire coat hanger to physically damage the uterus in a desperate bid to prevent fetal development.
* In the original flash version of *The Binding of Isaac*, this item was unlocked by default.

V1.02

## Documented changes

### Fixes

* Fixed white textures for players using OpenGL 2.x due to older graphics hardware. If "ogl2" beta is used, make sure to opt out of the beta to upgrade properly.
* Fixed window disappearing on startup on Windows. The game window would show up for a short amount of time and then disappear, while the music was still playing. In case the bug is still present, press Windows + Left, or Windows + Right (the little key with the Windows logo, and one of the arrow keys).

V1.06.0183

## Documented changes

### Fixes

* Reverted the steam cloud saving change from the last update due to reports of the game being unable to find its save data if cloud saving was turned off.
* Fixed a crash releated to having multiple trinkets.
* Fixed a bug where the unlock checks for ending 19 and final were reversed in the cutscene menu.
* Gameplay adjustments.

### Modding

* Some changes were made to Lua sandboxing due to security concerns. Here's how they affect you:
	+ If you used `require("mobdebug").start()` in your mods, that should be replaced with `StartDebug()` to prevent your script from hitting an error, since that only works with `--luadebug` enabled. This means you'll have to update any lua mods you've released with that line left in.
	+ For now we strongly recommend running workshop mods only with `--luadebug` disabled. This recommendation may be retracted in a later update.
	+ See the debugging page in the tools/luadoc documentation for a tutorial on setting up the debugger.
* Changed the way unpacked resources are loaded, due to issues players were frequently seeing where unpacked resources were becoming outdated, players with incompatible legacy mod files or mods applied by the legacy method. Now the game prefers to load files from the pack file first, and if that fails, loads from loose files.
* Fixed const-ness of player entity passed to certain callbacks.
* Fixed an issue where a function for getting the screen position of an entity didn't account for the camera offset or screen shake.

## Undocumented changes

### Changes

* Spectral Tears now go through Stoneys.
* The Double Trouble room with a Mega Fatty and a Sisters Vis was changed; Mega Fatty was replaced with a Larry Jr..
* The Double Trouble room with 2 Freds and 2 Gurdys was changed to only have 1 Fred.

Ultra War

**Ultra War** is a boss added in *The Binding of Isaac: Repentance* and is the third of the Ultra Harbingers fought before The Beast in Home.

## Behavior

### Phase 1

Ultra War charges in from the side of the screen and has two attacks which he alternates between:

* Throws a large, Giga Bomb that deals contact-damage and explodes mid-air in a cross pattern that spreads across the entire screen, similar to  Bombs. The Bomb also releases a burst of 12 lines of 4 projectiles outward when it explodes. This attack is repeated 3 times.
* Charges off-screen, then wraps around the bottom of the screen 3 times, creating 4 to 6 pillars of harmless light in alternating positions across the screen, from which large lava projectiles launch upwards with staggered timing.

### Phase 2

Ultra War dismounts from his hobby-horse and has two new attacks which it alternates between:

* Chases Isaac, then lunges diagonally downwards in Isaac's direction. After, Ultra War releases 4 streams of fire in the cardinal directions as well as a small burst of slower moving fires in all directions. This attack is repeated 2 times.
* Lunges diagonally downwards while holding a large bomb which explodes in a cross pattern that spreads across the entire screen. Ultra War then bounces across the sides of the screen 3 times while moving upwards before plummeting into the lava below. When Ultra War emerges, he creates 4 to 6 large lava projectiles that launch upwards with staggered timing.

* Upon death, Ultra War explodes, which can damage Isaac at close range.

* Ultra War tossing a bomb, first phase.
* Ultra War in his second phase.

* Concept sketches for Ultra War's behaviors.

## Notes

* If Isaac has the , the Giga Bombs Ultra War throws will be defused and fail to explode, after which they can be picked up or left to fall into the lava.
* Ultra War's Giga Bombs can be killed by  shots.
* The lava projectiles can be slowed and knocked down with certain slowing items such as Censer and high knockback tears.

## Trivia

* Ultra War, like the other Ultra Harbingers is an upgraded version of his regular counterpart, War.
The Binding of Isaac: Afterbirth/Additions

## Items

95 new items were added in the expansion: 19 activated items and 76 passive items.

## Trinkets

29 new trinkets were added in the expansion.

## Pickups

### Chests

 Eternal Chests
* Eternal Chests are similar in appearance to Gold Chests, except they glow bright blue instead of gold, like a soul heart. They require one key to unlock, but can be reopened a random amount of times, each time requiring another key. They can be found in Angel rooms, in I AM ERROR Rooms and rarely in a normal room. Their loot is similar to Golden Chests, but there is a 25% chance they will drop nothing upon opening. If they contain nothing or an item, they will no longer be able to be reopened.

 Spiked Chests
* Spiked Chests are purple colored chests with spikes protruding from them that will deal damage to Isaac upon opening unless he has the Holy Mantle active, which nullifies the damage, or if found in The Chest/Dark Room, where they are free to open. They can be rarely found upon completing a room or in greed mode shops. Their loot is similar to Brown Chests. Unlike other chests, they do not appear on the minimap.

### Sacks

 Mystery sack
* Spawns 1-4 random pickups upon touching it. It will not drop any hearts, pills or chests, and they have an increased chance to drop batteries.

## Entities

### Beggars

 Bomb bum
Bomb Bums are extremely rare, and ask for bombs. Each bomb donated has a chance to have him drop 1-2 bomb pickups or an item from the Bomb Bum Item Pool. After spawning a pedestal item, the Bomb Bum will disappear and can no longer be donated to.

Wormwood

**Wormwood** is a boss added in *The Binding of Isaac: Repentance* that can appear in Downpour and Dross.

## Behavior

* Lunges from a pit towards Isaac, releasing 4 projectiles in the cardinal directions in the air. Wormwood then chases Isaac in a zig-zag pattern, before eventually returning to a pit.
	+ If Wormwood lunges out of a pit and lands on top of another large pit, he returns back into that pit.
	+ Eats any Bombs dropped in his path same as Chub while chasing Isaac, stunning him for a moment before dealing considerable damage.
* Partially emerges from a pit and fires a spray of disorganized projectiles at Isaac before re-submerging.
* At 33% health, Wormwood pierces the ground with his tail at Isaac's location with a short delay 3-6 times. Pits are created where Wormwood pierces the ground. Afterwards, Wormwood charges out from inside the left or right wall horizontal to Isaac's location while spawning 3 Small Leeches. He then chases Isaac for a short duration before returning to a pit.
	+ Wormwood can never create a pit in a spot that would trap Isaac.
	+ Wormwood takes increasingly reduced damage after reaching 33% HP until he performs this attack and takes only 20% damage while performing this attack.

## Gallery

* Wormwood in-game.
* Wormwood's tail.
* Wormwood's splash art when encountered in Dross.
* Wormwood's appearance in Dross.
* Wormwood's cut appearance in the Corpse in *Antibirth*.
* Concept art for Wormwood.

## Trivia

* His behavior and appearance is reminiscent to that of Pin, and is a variant of it.
* When encountered in the Dross, the color palette of Wormwood and his attacks are altered to fit the floor. Lil Blub also features this.
* His name is a reference to the Biblical Wormwood. It is a star that, according to the Book of Revelation, will fall on a third of the Earth's water, which will turn the water bitter and deadly to drink.
* In the *Antibirth* mod, Wormwood could be encountered as a degraded boss in the Corpse, and would take on a red color palette.
	+ The red color palette is still present in the files of Repentance, despite going unused.
	+ This red color palette can still be seen if Wormwood is spawned in the Corpse.
Wait What?

**Wait What?** is an activated item added in *The Binding of Isaac: Afterbirth †*.

## Effects

* Upon use, Isaac farts, knocking back enemies and their shots. It also sends out rock waves that deal 10 damage per tick to nearby enemies and break obstacles.
* Shots deflected by Wait What? farts deal 6 damage if they would've hurt Isaac for half a heart, and 7 for a full heart.

## Notes

* This item is identical to  in appearance.
* has a small chance to turn into this item upon pickup.
* Each run has a chance of replacing Butter Bean with Wait What? in item pools. Both items generally do not exist during the same run.
* This item is useful for opening Secret Rooms, Super Secret Rooms, Bedrooms and the path to Mines. In Bedrooms, it can also open up the passage under the carpet.
	+ To break open a secret room, the wall must be hit with one of the rock waves, not the gas cloud, so Isaac needs to stand a few steps away from the wall.
* The earthquake can open Bomb Chests.
* The earthquake can destroy Shopkeepers.
* The earthquake can be used to blow up the Donation Machine or activate/blow up a Shop Restock Machine.

## Synergies

* : Shoots a flame behind Isaac upon each use of Wait What. Despite  not duplicating Wait What's shockwave, the flame shot is duplicated.
* : Spawns white glowing wisps on the middle ring that don't shoot. The wisps invoke the effect of Wait What? when destroyed and do not persist between rooms.
* : Shoots a flame behind Isaac upon each use of Wait What. Despite  not duplicating Wait What's shockwave, the flame shot is duplicated.

## Trivia

* The item description is a reference to a brand of margarine named "I Can't Believe It's Not Butter!".
* Unlike , this item has no unlock condition, meaning it's possible for the player to find it right away, making the joke and reference slightly confusing.
	+ Wait What? no longer shows up naturally in any item pools, however it has a chance to replace  in any run.

Utero

*(chapter 4)*

The **Utero** is an alternate floor to the Womb. Unlike other alternate floors, the Utero does not need to be unlocked, aside from unlocking the Womb. While the theme of Utero overlaps heavily with the Womb, it appears to emphasize gore and disfigurement rather than its counterpart's focus on 'intact' viscera, though the difference in enemy make-up is still more subtle compared to other floors nonetheless. Its walls are slightly different, and the floor contains several new enemies that are bloodier and more deformed, as well as more enemies borrowed from later chapters, such as the Cathedral and Sheol.

Like the Womb, all damage that is taken on this floor and onwards deducts a full heart from the player's health (unless the player has ), regardless of the source.  While in the Utero, a dark yellowish desaturated screen shader and a warping effect will be applied to the screen, making it appear as if the area is submerged in fluid and further distinguishing the floor's appearance from the Womb.

## Bosses

### Final Boss

Mom's Heart will always appear in the second floor of this chapter or in the last boss room if Curse of the Labyrinth is active. Once It Lives is unlocked, it will appear instead of Mom's Heart.

## Unlockable Achievements

* Eden - Complete Chapter 4.

* Pop! - Beat Chapter 4 without taking damage.

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

## Music

* The music for the Utero is titled *Viscera*. The term “viscera” refers to the internal organs in the body. The Womb shares this same track.
* The music for the Utero is titled *Caesarian*. A caesarian is a medical procedure where a baby is surgically removed from the mother due to complications during birth.
* 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*]

## Trivia

*Utero* is the ablative or dative form for the Latin word and medical term "uterus", meaning "womb", and it probably stands for the expression *in utero*, "within the womb", which refers to certain surgical procedures or other occurrences taking place inside the womb or during the length of time that a fetus is in the uterus of the pregnant female.

XXXXXXXXL

**XXXXXXXXL** is Challenge #21. This challenge changes *all* floors to be the size of XL Womb but does not combine the floors of each chapter. The goal is to defeat Mom's Heart/ It Lives. Alternatively, you can defeat The Lamb by teleporting to Dark Room via a Sacrifice Room, or  Delirium if the portal to The Void appears after defeating Mom.

* Teleporting to the Dark Room via a Sacrifice Room is no longer possible, since the challenge does not end in the Dark Room.

## Difficulty

Due to the floors being much bigger, it makes important rooms like Treasure Rooms and Shops take significantly longer to find, which can make the run difficult if Isaac has rather weak items. It also makes Secret and Super Secret Rooms much harder to find. Although all floors are technically XL, there is only one treasure and boss room on each floor. On the plus side, since there are more rooms, there are more opportunities to generate pickup items.

## Strategy

* Items and pickups that reveal the map are very crucial, allowing easy maneuvering between Special Rooms throughout floors.
* Items that provide benefits based on clearing rooms, like , will help Isaac significantly because of how many rooms he will go through in this challenge.
* Teleportation cards, such as The Stars and The Hermit, are very valuable, as they allow easy access to Special Rooms. The Emperor is especially powerful, as it can be used to skip the entirety of a floor.
* Avoid items that teleport Isaac at random, such as , as they can significantly slow down progress by potentially teleporting him to the other side of the map. Picking up the  is not recommended for the same reasons.
* Planetariums are very useful for this challenge.  can be used to find the boss room,  can break doors with ease, and  allows you to walk through rooms with ease. Considering you might skip an item room or two anyway in the interest of time, this can be a very effective way of completing the challenge.

## Notes

* Curse of the Labyrinth can still spawn as normal, combining the two floors as normal, and causing there to be two treasure rooms and boss rooms. The size is unchanged.
* It is very rare to start next to a treasure room in this challenge.

## Reward

* Gold Heart - Complete **XXXXXXXXL (challenge #21)**.

Super Gluttony deals a whole heart of contact damage.
