Keeper's Bargain

**Keeper's Bargain** is an unlockable trinket added in *The Binding of Isaac: Repentance*.

## Trivia

* Meconium is the earliest stool of a mammalian infant.
Modding (Rebirth & Afterbirth)

Modding Rebirth & Afterbirth is limited to editing and replacing existing assets unless you hack the .exe yourself.

## Installing Mods

Mods made for Rebirth & Afterbirth must be installed manually into the game's resources folder.

To properly install mods for this version of the game, you must place what is inside of the mod's resource folder into the resources folder at the file path above.

## Limitations

Modding for this version of the game is limited to replacing existing files. Custom code (such as LUA code) cannot be executed, making most custom logic impossible. However, some mods have made attempts to work around this limitation by abusing certain default game logic - such as adding additional events to a monster's animation file. This could result in, for example, an enemy firing two projectiles instead of one.

* /  / : Affects items spawned by the box.
* : Items spawned by Keeper's Box are purchased with red heart containers and pickups are purchased with health, just like a regular shop item. This is if Isaac is not in a Devil Room, a Black Market, where they will again cost money.

Mom's Bottle of Pills

* This item belongs to the  set. Collecting three items from this set will transform Isaac into his mother.

Each color may fire tears that confuse, poison, petrify, burn, or spawn troll bombs. Each tear effect is assigned to one color of pill wisp based on the current seed. The only color pill wisp without a tear effect also spawns a hostile Spider when destroyed. For the troll bomb effect, the pill itself spawns the troll bomb instead of the tear, and the chance for it to do so is independent of whether or not its tears hit anything.

## Gallery

* 3DS The icon of Mom's Bottle of Pills as seen on the lower 3DS screen.

## Trivia

* In the original *The Binding of Isaac*, this item was unlocked by donating to Blood Donation Machines 20 times.

## Effects

## Synergies

* / : Provides infinite charges by clearing some enemies then leaving the room, and repeating.
* / : Allows the possibility to generate unlimited Hearts.

* Tainted Keeper: Leaving and re-entering the room allows for limited coin farming; however, enemies in rooms Tainted Keeper has already visited will eventually stop dropping coins.
* : Allows the player to go through rooms at a quicker pace due to the invisibility.

## Trivia

* Mercurius' effects reference the Roman god of travel and communication, Mercury, who wore winged shoes and a winged hat.
* Mercurius is the biggest static speed upgrade in the game.
* Despite Mercurius preventing doors from closing, the sound of doors opening can still be heard after clearing a room with enemies.

* In the original *Binding of Isaac*, Little Steven could only be dropped by Steven, 80% of the time.
Mole

It chases Isaac by burrowing in the ground (characterized by small, moving rubble on the surface). When it gets near Isaac, it pokes out of the ground and fires 3 blood shots at him. It will then jump to a nearby tile leaving a Poop where it jumped.

## Variations

### Stage HP

 80
 0

### Tainted Mole

The **Tainted Mole** is a stronger, distorted version of the regular mole.

It burrows through the ground, creating rockwaves in the direction it moves in. When it gets near Isaac, it pokes out of the ground, creating a ring of rock waves (similar to the Roundy) and fires 3 blood shots at him 4 times. It will then jump to a nearby tile leaving a Poop where it jumped.

## Gallery

* A Mole's appearance in a dark room with its eyes open.

## Trivia

* The Mole first appeared in the *Antibirth* mod where it would not create Poops upon leaping, but instead Pits.

## Trivia

* The phrase "Itchy, tasty..." is a reference to the Keeper's Diary from *Resident Evil*.

His final entry consists of two words: "Itchy. Tasty.".

Launch Options

Launch options are special options that you can set in Steam before launching the game. They are also referred to as "flags".

## Setting Launch Options

* Open Steam.
* Click on the "Library" tab near the top of the screen.
* Right-click on "The Binding of Isaac: Rebirth" and select "Properties".
* Click on the "General" tab on the left.
* At the bottom of the screen, there will be a box to specify "Launch Options".

## The Launch Options

There are currently two different launch options:

### `--luadebug`

Normally, mods are restricted from doing anything harmful, like reading files from the file system or communicating over the network. Setting the `--luadebug` flag lifts these restrictions, allowing Lua code to use the `require()` function to require arbitrary files and to use the "socket.lua" library.

As the name implies, this should primarily be used by mod developers for debug purposes, not for general use. You should never enable `--luadebug` unless you have a very specific reason and you know what you are doing, as it could lead to your computer being compromised. Mods asking you to enable this without a specific reason (e.g. needing network capability) should probably not be trusted.

### `--networktest`

This must be set to enable the "secret" online multiplayer mode. It is recommended to remove this flag when you are done playing multiplayer, as anyone on Steam can disrupt your future runs by pulling you into their games.
Lusty Blood

### Collection Grid

*(page 4, column 6, row 3)**(page 4, column 6, row 3)**(page 4, column 7, row 3)*

### Unlock Method

 Defeat Ultra Greed as  Samson

This article is about **Lusty Blood**, not to be confused with Bloody Lust.
**Lusty Blood** is an unlockable passive item added in *The Binding of Isaac: Afterbirth*.

## Effects

* Each time an enemy is killed, Isaac gains a damage boost for the current room.
	+ Each kill increases damage by 0.5, up to a maximum of 5 damage after 10 kills.

## Notes

* Some summoned enemies like Rag Man's Raglings do not trigger the effect when killed.
* Mr. Maw does not trigger the effects of Lusty Blood, even after splitting.
* Blowing up a Shopkeeper will grant Isaac a damage bonus as well.

## Synergies

* : Both of the smaller enemies produced by Meat Cleaver add to the damage bonus, allowing rooms with few enemies to grant much more damage.
* : Both the item and the trinket stack, granting 1 damage per kill. With 100% proc rate on the Lock, Isaac may gain up to 10 damage after 10 kills.

## Interactions

* Ace Cards: Enemies that are turned into pickups don’t count towards the Lusty Blood counter.
* /: Enemies that are turned into poop don't count towards the Lusty Blood counter.
* Freeze Effects: Enemies that are frozen don't count towards the Lusty Blood counter.
	+ Because of this interaction, when Isaac has , only enemies killed by icicles from statues, bombs, familiars and other sources will increment Lusty Blood's counter, thus rendering Lusty Blood quite difficult to use.

## Trivia

* Lusty Blood has the same effect as  from the original *The Binding of Isaac*.
Jupiter

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

## Effects

* Grants two Red Heart containers, of which half a heart will be filled.
* -0.3 Speed.
* Standing still causes Isaac to build up speed at a rate of +0.25 per second, up to a +0.5 speed bonus.
* Isaac charges up while standing still. Moving releases a fart cloud behind Isaac, damaging and inflicting Poison on enemies that pass through it and draining the speed buff at a rate of -0.25 speed per second. The fart clouds are left behind for the duration of the speed buff.
	+ The fart clouds deal 0.5x Isaac's damage per tick (1.5x Isaac's damage per second), and last ~2.5 seconds.
* Isaac is immune to Poison from enemies, such as Gasbag or Mushrooms.

## Notes

* As the speed buff requires Isaac to stand still, Jupiter is effectively a speed down.
* The fart clouds are mechanically independent of the speed increase. Even while at max speed, the fart cloud must be charged by standing still.
* Jupiter acts solely as a flat +0.20 speed boost for Tainted Forgotten with no other effects.

## Synergies

* : Damaging enemies with the fart clouds will not take away Isaac's camouflage.
* : Stays in effect even while using Dark Arts, allowing Isaac to deal more damage to nearby enemies while invulnerable.
* : Greatly increases size of fart clouds.

## Trivia

* Jupiter, as well as , was designed for the original *Antibirth* mod, but never actually implemented until *Repentance*.
* Jupiter's effects and pickup quote reference the planet Jupiter's nature as a gas giant, being composed mainly of hydrogen and helium in gas and liquid form.
* The item's ability to create fart clouds after standing still and poison immunity could be a reference to *Nuclear Throne*, where the character Frog has similar abilities.
Juicy Sack

### Collection Grid

*(page 3, column 1, row 7)**(page 3, column 1, row 2)**(page 3, column 2, row 2)*

**Juicy Sack** is a passive item.

## Effects

* Spawns a familiar that follows Isaac, leaving a trail of white creep that slows enemies.
* Spawns 1-2 Blue Spiders after every room.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a humanoid spider.

## Notes

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

## Synergies

* : Juicy Sack spawns an extra Blue Spider.
Jawbreaker

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

## Effects

* Adds a chance to shoot a tooth instead of a tear, which deals x3.2 Isaac's damage; mechanically identical to the passive item .

## Notes

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

1

10
−

⌊

L
u
c
k

⌋

{\displaystyle \frac1 { 10 - \left \lfloor \mathit{Luck} \right \rfloor}}

	+ At base luck (0), the chance is 10%, maxing out at 100% at 9 luck.
* This trinket is identical in function with , so all interactions with that item apply to this trinket as well.

## Interactions

* : Activation rates are individually applied to each tear, effectively allowing for higher amounts of teeth. However at 9 Luck, this trinket is no longer needed, as Tough Love will already guarantee that every shot is a tooth at that point.

## Trivia

* Jawbreaker is from the *Antibirth* mod.
	+ This trinket made its first debut in the Community Remix mod for Flash Isaac, previously being called ‘The Jaw Breaker’.

* : Isaac can use Plan C on end-game bosses (e.g. Hush, Delirium) and survive, although, if going for unlocks, he will get Lazarus's post-it notes instead.

## Gallery

* Tainted Forgotten being revived as  Lazarus.

## Trivia

* When  Tainted Forgotten dies and respawns using this item, the resulting  Lazarus Risen appears as a skin-colored pile of bones with Lazarus' head on top. This is purely visual and Lazarus Risen is still able to move and shoot as normal. This was originally a bug, but was left in because the developer Kilburn found it funny.

Min-Min

**Min-Min** is a boss added in *The Binding of Isaac: Repentance* that can appear in Downpour.

## Behavior

### Phase 1

Min-Min floats slowly towards Isaac and performs the following attacks:

* Spits a Willo at Isaac which fires a projectile at him before returning to orbit around Min-Min. Min-Min can have a maximum of 4 orbiting her. Willos do not deal contact damage.
	+ This can be done multiple times in quick succession until the limit of 4 Willos has been reached.
	+ Willos orbiting Min-Min occasionally fire a projectile towards Isaac.
* Once Min-Min has 4 orbiting Willos, she periodically causes them to fire 3 projectiles outwards. If any Willos are killed during this attack the remaining ones perform this attack uninterrupted.

### Phase 2

In this phase, Min-Min burns away the husk surrounding her, and can now have a maximum of 7 Willos orbiting her. She will continue to float slowly towards Isaac and has new attacks:

* Min-Min spawns up to 4 Willos around herself and then causes all orbiting Willos to fire 3 projectiles outwards.
	+ Willos orbiting Min-Min still occasionally fire a projectile towards Isaac.
* Spits a Willo at Isaac which fires a projectile at him before returning to orbit around Min-Min.
* Causes the current orbiting Willos to fire 3 projectiles outwards.
* Sends her orbiting ring of Willos to chase Isaac. After a few seconds, they return.
* Disappears and creates several groups of lights on the ground. One group at a time, Willos appear from the lights, fire at Isaac, and disappear.

Upon Min-Min's defeat, all spawned Willos die alongside her.

* Min-Min in her second phase.
* Maid in the Mist, the cut boss that Min-Min would replace.
* Concept sketches of Min-Min's behaviors at phase 1.
* Concept sketches of Min-Min's behaviors at phase 2.

## Trivia

* Min-Min is confirmed to be female, as shown in this tweet.
* In her first phase, Min-Min is hiding within what appears to be a drowned and bleached corpse of The Husk.
	+ In a way, this corpse can be seen as a posthumous version of Lil Blub.
* Min-Min may be named after Min Min lights, a light phenomenon that has often been reported in outback Australia, where remote lights appear on the horizon and appear to follow people around.
* Min-Min in her first phase is very similar to the Mullighoul monster as they both are white creatures, have a ball of light in the mouth, and shoot out Willos.
* In the files of Repentance, there is an unused Boss Portrait for a Boss called "Maid in the Mist". Unlike the other unused Bosses, there are no files for this boss. This is likely because she was early concept for what would become Min-Min in the final game, as they are both female, share a Willo theme, and were both assigned the enemy ID **913** according to their file names.

### Collection Grid

*(page 4, column 16, row 3)**(page 4, column 16, row 3)**(page 4, column 17, row 3)*

## Interactions

* : Spawns two charming farts on top of each other  and the cloud deals double damage.

## Trivia

## Effects

Mars

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

## Effects

* Double tapping a direction makes Isaac quickly dash in that direction.
	+ Isaac is immune to damage from all sources during the dash, with the exception of Blood Donation Machines, Devil Beggars, and similar self-damage active items.
	+ The dash deals damage equal to 4x Isaac's damage + 8.
	+ The direction of the dash can be changed by holding another button.
	+ The dash has an approximate 3 second cooldown.

## Notes

* The dash can be used to enter Curse Rooms and open Spiked Chests/ Mimic Chests without taking damage.
* The dash can destroy Shopkeepers.
* With a controller, tapping the joystick is rather inconsistent, and the dash can often activate by accident. Using the directional pad instead is recommended.
* When Mars's dash is charged, Isaac will occasionally flash brightly, and visible steam will emit from his nose.
* Extra care needs to be taken with this item, as tapping for precise movements too quickly will cause a dash.

## Synergies

* : Kamikaze can be used without taking damage while dashing.
* / : Lowers the dash cooldown to approximately 1.5 seconds.

* Spits out a single larger Small Leech that chases Isaac instead.
* Fires 6 streams of projectiles outwards in a radial burst. These projectiles deal a full heart of damage.
* Jumps once towards Isaac, creating a burst of disorganized arcing projectiles upon landing.
	+ Lil Blub can only use this attack when below a certain threshold of HP.

The previous two attacks also cause any Small Leeches that are swarming around Lil Blub to start chasing Isaac. Lil Blub cannot use any of these attacks if there are 6 or more Small Leeches in the room.

* Jumps towards Isaac 3-5 times, firing projectiles in the cardinal and diagonal directions upon landing. The cardinal shots are faster and travel further than the diagonal ones.
	+ Any leeches Lil Blub lands on are instantly killed.
	+ Lil Blub can only use this attack when below 25% HP, and greatly prefers using it if he can.

Upon death, he spawns 2-4 Small Leeches and bursts into a fountain of projectiles that rain down for a few seconds in a wide area.

## Gallery

* Lil Blub in-game.
* Lil Blub's splash art when encountered in Dross.
* Lil Blub's appearance in Dross.
* Concept art for Lil Blub.

## Trivia

* Lil Blub's original name in Antibirth was "Beelzeblub", and he is referenced as such in the game files.
	+ In pre-release content for Repentance, his name was Lil Bub, without the "L". The reason for this change might've been to avoid confusion with a famous cat of the same name.
* Lil Blub appears to be a drowned version of The Duke of Flies.
	+ It is possible that the shell worn by Min-Min is his posthumous version, as this shell that resembles The Husk, the posthumous version of the Duke of Flies.

* : Doubles puddle size.

## Trivia

* The Lemon Party Pill will drop a larger pool (almost the size of the room, if you stand in the middle) of Lemon Mishap.
* In the original *Binding of Isaac*, Lemon Mishap was the only activated collectible to have an icon different to its item (the item was a lemon, but picked up it was a glass of lemonade).
	+ The item  is a reference to this.
* In the original *Binding of Isaac*, Lemon Mishap was widely considered as one of the worst active items in the game, due to low damage and small creep size, making it both hard and unreliable at killing anything. In *Rebirth,* Lemon Mishap was buffed considerably.
* This item is used in When Life Gives You Lemons (challenge #12)).

## Gallery

* Lemon Mishap on use.
* 3DS The icon of Lemon Mishap as seen on the lower 3DS screen.
