Uranus

**Uranus** is a passive item.

## Effects

* Isaac fires ice tears. Enemies killed by ice tears will become frozen.
	+ Touching a frozen enemy will send it sliding in the direction Isaac pushed it, damaging other enemies it hits. When a frozen enemy hits something solid, it will shatter, sending ice shards in all directions. These ice shards can also freeze enemies.
	+ Champion enemies still have a chance to drop their drops if pushed.
	+ Enemies surviving the ice shards will be slowed down.
	+ Disables the abilities of some enemies when killed (for example, a Pale Fatty can't become a Blubber if frozen and shattered).

## Notes

* This item's freezing ability is the same as Freezer Baby's

## Gallery

* Concept art for Antibirth items, including Uranus.

## Bugs

 ****Bug!**** When the last segment of Carrion Queen is frozen, the head and the second segment become indestructible. One can still kill the Carrion Queen by feeding it a bomb. Alternatively, if the player manages to kill the Carrion Queen in a really short amount of time, she still dies normally and her last two segments will be exactly the same as normal frozen enemies.
Jacob's Ladder

Defeat Isaac as Jacob & Esau.

**Jacob's Ladder** is a passive item.

## Effects

* Generates a ladder in the starting room of each floor which leads to an Angel Room.
	+ The ladder is always present, so this Angel Room can be re-entered multiple times.
	+ This Angel Room is different from the Devil/Angel Room generated after the boss fight and is, therefore, is not affected by devil deals made in the run.

## Notes

* Angels spawned from angel statues in this room will normally drop corresponding key pieces.
* If Isaac has already entered the Angel Room before a boss fight, no Devil/Angel Room will be generated in the Boss Room after the fight.
	+ Because of this, it's suggested to enter the Devil/Angel Room generated after defeating a boss before entering the Jacob's Ladder Angel Room, potentially granting more rewards.
* If the starting room is swapped with another room under the effect of Curse of Maze, the ladder will be moved along with it.

## Bugs

* If you edit in this item on the first floor, going to the Angel Room with it will cause the entire game to speed up, similar to if it had been "speedhacked." This effect lasts until you exit to the menu and continue.
* If you lose Jacob's Ladder due to Missing No. you will still be able to enter an angel room when starting a floor, but the ladder will disappear after using it, leaving you trapped in the angel room.

## Trivia

* Jacob's Ladder is a reference to The Book Of Genesis from the Old Testament. In Genesis 28:10-19 Jacob rests on his journey and has a dream; in the dream, he sees a ladder that serves as the connection between Heaven and Earth.
* This item is unrelated to the Afterbirth + Item of the same name.
	+ It was renamed The Stairway when it was ported into *Repentance* to avoid a naming conflict.
* The item description might be a reference to "Stairway to Heaven", a song by Led Zeppelin. The *Repentance* description "May You Get What You Came For" makes this more deliberate.
* This item was significantly reworked in *Repentance*. It now leads to a unique angel shop, where Angel items can be bought with money. However, the ladder will despawn after leaving the starting room. Entering this room no longer affects the Devil/Angel chance for the floor.

Sausage

**Sausage** is a passive item.

## Effects

* Grants a heart container and fills all empty red heart containers.
* +1.0 damage.
* +5.25 range.
* +0.5 tear height.
* +0.7 tears.
* +0.3 speed.
* +0.16 shot speed.
* +1 luck.

## Trivia

* This item's item sprite, costume effect, and item pool suggest that this item based on the double entendre of "hide the sausage".
* This item is unique among items with the "all stat up" pickup line in that it increases all stats; most all stats up items don't boost luck.
* The Sausage item may be a reference to the fact that Sausages are the lead developer Kilburn's favorite food.
* Sausage's costume sprites are referred to as "Sosig" in the game files.
* When Sausage was ported into *Repentance*, it lost the increase to tear height but now increases the chance to encounter a Devil/Angel Room and Planetarium each by 6.9%.
Wormwood

**Wormwood** is a boss that appears in Downpour.

## Behavior

Wormwood has several attack patterns:

* Pops out of the water and spits a spray of tears at Isaac.
* Occasionally, he jumps out of the water and charges towards Isaac. Shortly after jumping out, it will shoot tears in cardinal directions.
* Once he reaches about 33% health he will execute a series of attacks.
	+ Swims under Isaac and punches his tail through the ground 5 to 7 times, which can damage Isaac and leave holes in the ground.
	+ Afterwards, the screen starts shaking. After a short delay, he will break through one of the walls to the left or right and charge at Isaac at a high speed. He will spawn Small Leeches as he crashes through.
	+ After this attack, he resumes using his first 2 attacks.

## Notes

* While jumping, he can jump over Isaac's tears.
* Wormwood can only emerge and submerge at holes in the floor.
* The holes he leaves in the ground may leave certain exits to the boss room inaccessible.
* The tails that he punches up through the floor cannot be damaged.
* When encountered in The Womb, Utero, or The Corpse, Wormwood changes color to match the floor.

## Trivia

* Wormwood's attack patterns bear high similarity to Pin's.
* 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.

## Gallery

* Wormwood ingame.
* Wormwood's tail ingame.
Orphan Socks

**Orphan Socks** is a passive item.

## Effects

* +0.15 Speed.
* Grants two soul hearts.
* Grants immunity to floor hazards like spikes and creep.

## Notes

* Although Orphan Socks allows Isaac to enter Curse Rooms without taking damage, Isaac still takes damage upon leaving.
* In the Cursed! challenge, Magdalene is immune to cursed doors with Orphan Socks.

## Trivia

* This item originated from the *Binding of Isaac: Community Remix* mod.
Small Leech

**Small Leeches** are common minor enemies encountered in Downpour. They swim towards Isaac to do contact damage and can travel across gaps. Rocks, on the other hand, will block them and if so they will usually make no effort to path-find their way around them. Small Leeches also possess very slippery movement, so if the player dodges past a pursuing Small Leech, the time it will take to re-direct itself back at the player again can leave them vulnerable.
Black Mushroom

**Black Mushroom** is an active item. The item has a short recharge time and can be used repeatedly in the same room increasing all the effects.

## Effects

* Increases tear rate for the current room.
* Temporarily decreases movement speed and distorts the screen and sound.
	+ The movement speed decrease and distortion persists across rooms. The negative effects decrease at the rate of one Black Mushroom use per room cleared.
	+ If used too many times, the screen will become distorted to the point of unplayability.

## Notes

* The more times Black Mushroom is used, the longer the cooldown becomes.
* This item originated from the *Binding of Isaac: Community Remix* mod.

## Trivia

* This item was renamed Wavy Cap when it was ported into *Repentance*. It was also buffed to keep the tears up between rooms as well as the negative effects.
Small Maggot

**Small Maggots** are Maggot variants found only in the Corpse chapter. They are a minor enemy that mostly serve aesthetic purposes rather than actual threats, but can still deal contact damage. They slowly move around aimlessly and have low HP but are usually found in massive groups.

Many enemies in the Corpse spawn Small Maggots. Destroying a Polyp in the Corpse also has a small chance to spawn three of them.
Mars

**Mars** is a passive Item.

## Effects

* Double tapping a direction makes Isaac quickly dash in that direction.
	+ Isaac is invincible during the dash.
	+ The dash deals 4 times your damage.
	+ The direction of the dash can be changed by holding another button.
	+ The dash has an approximate 3-second cooldown.

## Synergies

* Thunder Thighs/Leo: Can destroy obstacles while dashing.
* Midas Touch: Dash will freeze enemies and instantly kill them.
* The Virus: Dash will poison enemies.
* Monstrance: Damaging aura remains in effect during dash, allowing for enemies not hit by your dash to be damaged as well.
* Aries: Dash will deal the additional contact damage of Aries which is slightly helpful for bosses.

## Notes

* The dash can help Isaac enter and leave Curse Room without taking damage.

## Trivia

* Picking up Mars makes Isaac look similar to War. In Roman mythology, Mars is the god of war.

## Gallery

* Isaac performing a dash
Almond Milk

**Almond Milk** is a passive item.

## Effects

* Significantly increases fire rate.
* x0.3 damage multiplier.
* Tears gain random worm and movement effects.

## Synergies

* Libra - Decreases fire rate slightly, but significantly increases all other stats, similar to how Libra and Soy Milk work together.
* Mom's Knife - Knife turns yellow. Fire rate increase causes the knife to travel further with a shorter hold time.

## Interactions

* Dr. Fetus - Allows the rapid firing of bombs. The worm effects apply to the bombs shot out. This can result in self-injury as the bomb's erratic patterns include zig-zagging and orbiting the user, which makes it difficult to avoid the explosion, especially if many bombs are fired at once.
* Soy Milk - Isaac's damage multiplier and fire rate will only be affected by Soy Milk, but the randomized tears from Almond Milk will persist, effectively decreasing Soy Milk's damage output by lowering accuracy with no benefit.

Birthright

Defeat ??? as Jacob & Esau.

**Birthright** is a passive item.

## Effects

* This item has a different pickup quote and effect depending on the character it is picked up as:

## Notes

* When taken by Isaac, if multiple items spawn (eg. Polaroid and Negative after beating Mom) both items get an alternative, but still only one can be taken, after that, all the other items disappear.
	+ However, the Shops still allows to the choice between alternatives of different items at the sale.

## Trivia

* This item originated from the *Binding of Isaac: Community Remix* mod, where it was known as 'Soul Script'.
* The item's new name and unlock requirement are likely a reference to the biblical story of Jacob and Esau, in which Esau trades his birthrights to Jacob in exchange for stew. The reference is strengthened by the Birthright's specific effect when taken by Jacob or Esau, allowing them to "inherit" the items of their brother.
* When Birthright was ported into *Repentance*, only ???, Bethany, and Jacob & Esau retained their Birthright functionality.
	+ Isaac had a slight alteration, having pedestals swap between two items rather than spawning two pedestals.
	+ Magdalene gains a single red Heart container but increases her maximum number of hearts to 18.
	+ Cain gains +1 Luck and spawns an upgraded Arcade on every floor.
	+ Judas gains The Book of Belial as a passive item that combines with any activated item, dealing damage to nearby enemies and granting a damage boost that scales with the number of charges that the item has, as well as having unique synergies with some items.
	+ Eve gains the effects of Whore of Babylon regardless of her health and has Dead Bird following her without taking damage.
	+ Eden spawns three random items that can come from any pool, and can pick one to take.
	+ The Lost will not see items that are detrimental or useless for him, rather than just no health up items.

## Bugs

 ****Bug!**** This item tends to randomly crash the game upon pick up. Most noticed when picking up this item with the Jacob & Esau character if the other character does not have at least 3 passive items.
 ****Bug!**** When picked up as Isaac, the game will often crash when a beggar or machine generates an item pedestal. ****Bug!**** The Lost may still get HP upgrades after using R Key item.
Stitches

**Stitches** is an active item.

## Effects

* Spawns a familiar that flies diagonally across the room, switching direction upon hitting walls.
* Swaps the positions of Isaac and Stitches when activated.
* Switching positions while Stitches is on top of an enemy or boss will deal high damage to said enemy, killing most enemies in a single hit.

## Synergies

* BFFS!: Isaac will emit 8 tears from his starting position when switching.

## Notes

* When playing with Jacob & Esau, if Jacob and Esau are close to each other, both of them will be transported. Otherwise, only the one who uses Stitches will be transported.
* Switching positions while Stitches is on top of a shopkeeper will destroy it, granting its pickups without needing to use a bomb.
* Switching positions will grant a very brief period of invincibility, which can allow free access to Curse Rooms.
* Switching positions while Stitches is on top of fires will destroy them. This includes blue fires.

## Trivia

* When this item was ported into *Repentance*, it was changed to be controllable with the fire keys, similar to ???'s Only Friend.
Lodestone

**Lodestone** is a passive item.

## Effects

* Adds a chance to fire magnetizing tears.
	+ Magnetized enemies attract other enemies, Isaac's tears, and enemy shots including their own.

## Notes

* The chance to fire a magnetizing tear depends on Luck, reaching 100% with 10 luck.

## Synergies

* Brimstone - The laser turns grey and magnetizes enemies, but does not curve towards enemies.

## Trivia

* A lodestone is a naturally magnetized piece of mineral magnetite.

Rotgut

**Rotgut** is one of the bosses that can appear in **Corpse**.

## Behavior

In its first form, Rotgut spawns stationary in the middle of the room. It has a few attacks:

* Protrudes a second mouth which spews brown shots, bones, Small Maggots, and Globin goo.
* Fires bloody shots in all directions.

When the first form is reduced to 0 health, it will start sucking in everything in the room. Once Isaac is sucked in, he's dragged into a Crawlspace-like area to fight two more forms.

In its second form, Rotgut is stationary in the bottom right corner of the crawl space. It has several new attacks:

* Shoots slow-moving curving bullets.
* Shoots a chaotic burst of blood projectiles similar to Monstro throughout the lower half of the room while spitting small maggots.
* Shoots a cluster of red bullets that fly in a wavelike pattern and fill up the bottom of the room.
* Fires one large explosive bullet that releases regular bullets in random directions upon exploding.
* Spews a burst of green projectiles along with a large poison cloud.
* Fires a Brimstone laser that covers the lower half of the room.

After the second form is defeated, a passage will open up in the bottom right of the room, leading to the third form.
In its third and final form, Rotgut is stationary and hangs from the ceiling, and has a few more attacks:

* Fires pulsating bullets in 7 directions.
* Causes bullets to fall from the top of the room. Once these bullets come in contact with a wall or floor, they split in two.
* Spawns a series of 4-5 leeches from either the left or right side of the room at Isaac's height.
	+ The last Leech has a chance to be an Adult Leech.

Once all three forms of Rotgut are defeated, Isaac is ejected out of the crawl space, returning to the boss room right before Rotgut dies properly.

## Gallery

* Rotgut's 2nd form

* Rotgut's Concept Art, By \_Kilburn.

## Trivia

* Rotgut's 1st form bears a strong resemblance with Nydus Worms from Starcraft II.
* Rotgut's 2nd form seems to be a giant maggot that has infested the corpse to feed off of it.
	+ This maggot has been nicknamed "Gus" by the developers.
* Rotgut's 3rd form looks like a dead/rotten version of Mom's Heart, explaining Rotgut's name.
* Rotgut is the name for grade of moonshine that is very poor quality, being poor enough to be deadly to drink. Isaac's mother was a known alcoholic, this could be the reason for rotgut's existence in her corpse.
* Rotgut is the name of a Super Meat Boy level, one of Edmund McMillen's games.
* Rotgut was significantly redesigned when it was ported into *Repentance*. Its first form was redesigned to a Fatty fused into the ground, while the third phase was changed to a non-specific organ. Only the maggot was unchanged.
Damocles

**Damocles** is a single-use active item.

## Effects

* Upon use, summons a sword that hangs directly above Isaac. As long as the sword hangs above Isaac, all item pedestals are doubled, spawning an extra item for every item spawned.
* After getting hit once with the item activated, at any time without warning, the sword may fall, instantly killing Isaac regardless of his health. The more hits Isaac takes, the more likely it becomes for the sword to fall.
	+ Using Blood Donation Machines, IV Bag, or Devil Beggars does not increase the chance for the sword to fall.

## Notes

* The chance for Damocles to fall is indicated by how far the sword swings back and forth.
* In Shops, and Devil Rooms, the extra item is free to take.
* In double Treasure Rooms and boss rewards with There's Options, four items will spawn, but you can only take one item from each pair.
* The only way to survive the falling sword is either through extra lives, by using items that would make you invincible, such as Gnawed Leaf or playing as The Lost. After the sword falls, extra items will no longer spawn.
	+ Be warned, however, that losing a life before the sword falls does not de-spawn the sword.
* When playing as Jacob & Esau the item, once activated, gives its full benefit while it only has a chance of falling once the character who used it gets hit.

## Trivia

* According to a story, Dionysius was a tyrant who was hosting Damocles for some time. Damocles exclaimed to him how fortunate he was. Dionysius in response offered to switch places with him so that he could have a taste of that fortune. Damocles accepted the king's offering and sat on the throne, having several servants under his will. He quickly noticed a sword hanging from a single horsehair directly above his head, making him beg Dionysius to exempt him from that very fortune.
* The item received a minor rework in *Repentance*, as Damocles will keep the same chance for the falling sword to activate regardless of the amount of times damage is taken.

## Bugs

 ****Bug!**** Double Treasure Rooms + There's Options + Birthright (when playing as Isaac) tend to crash the game with Damocles.
Tips/Jacob & Esau

## Tips

Jacob & Esau being two separate characters brings out some pros and cons.

Pros and cons
 Shares bombs , essentially doubling bomb picks
 Can separate items, avoiding bad synergies (eg: Soy Milk + Epic Fetus)
 Both can hold an active item
 both have in total 4 Red hearts, and one soul heart

Jacob & Esau can be hard characters to play as, even with the benefits it brings.

On stats, the brothers are very similar. being the same on speed, range and damage multiplier. We'll skip speed, since any speed modifier applies to both twins, with little exceptions like Libra,

In base of these stats, the player should give priorities to which character should get said item, in order to avoid having one character underpowered. Jacob has less damage and shot speed, while Esau has negative luck, less health and less tears. Even though both have the same base range, Jacob's shot speed reduces his effective range.

Apart of that, speed and range are the same as Isaac, so individually there's no much difference from playing Isaac.

They start without any item. So you should start building up from the start if possible.

If a room contains two item pedestals it is possible to pick up both items. Simply separate, line up and walk into both item pedestals simultaneously.

## Adapted controls

The problem doesn't lay on movement and aim (WASD and arrows), since both Twins share those. The main changes are made so Esau isn't limited.

Practice with the use of Q key, which changes from pills/cards to Esau's Active item. That forces you to consume any of these without even checking. This makes cards unpredictable and unreliable since most of their effects applies to the actual room or teleports the player, while you have to remember each pill color to avoid the negative ones. CTRL allows you to separate Jacob from Esau, which can be helpful to resolve puzzles, pass through narrow shots, or keep Esau away from damage.
Knockout Drops

**Knockout Drops** is a passive item.

## Effects

* Adds a chance to fire fist tears, which have massive knockback and briefly stun enemies.
	+ Knocked back enemies will do contact damage to enemies they collide with.
	+ Tears from Knockout Drops can even knock away stationary bosses such as It Lives or Mega Maw, although they'll snap back to their previous position.
	+ The chance to fire a fist tear depends on the luck stat, reaching 100% with 10 luck.

## Notes

* If a fist tear hits an enemy with multiple body segments like Chub, all segments are knocked back and collide with each other, dealing extremely high damage. It is possible to kill these enemies with only one fist.

## Synergies

* Brimstone/Technology: The laser knocks back enemies.
* Perfection: Since the item requires 10 Luck to activate every time, picking up this trinket when Luck is 10 or more will make the effect constant.

## Seeds

E1S6 63JC (First-floor treasure room)

Horf

The **Sub Horf** rotates and fires tears upon being knocked back. Sub Horfs are very prone to knockback and slide around, allowing them to fire tears for a longer duration. They always fire tears in whatever direction they face while being pushed.

### Notes

* When damaged but not knocked back, like using piercing tears or Brimstone, Sub Horfs will not fire tears nor rotate; they'll only make a grunting noise. Piercing shots make them extremely easy to deal with since they won't be firing back.
	+ Likewise, high knockback can make them shoot multiple times, so fighting them is more difficult with items that increase knockback such as Soy Milk.
D12

**D12** is an active item.

## Effects

* Re-rolls all obstacles in the current room.

## Notes

* Antibirth's D12 has a wider range of possible re-rolled obstacles than Afterbirth's D12. For example, it can re-roll obstacles into retractable spikes and red barrels.
	+ This functionality was later ported into Repentance in the 1.7.8 Update.

## Trivia

* This item exists in the Afterbirth DLC with a different appearance.
* This item first appeared in Community Remix but had a different effect of rerolling bosses.

## Gallery

* Reroll blocks in Devil Room
* Reroll blocks in Angel Room

Ball and Chain

### Found In

**Ball and Chain** are an indestructible enemy that rotate at various speeds around an obstacle which they are attached to with chains of varying lengths. Touching the chain does not harm Isaac. They can destroy rocks and other obstacles they come into contact with.

If the anchor obstacle is destroyed, the ball will be launched across the room at its current velocity, eventually coming to a stop. When the room is re-entered, the ball will be at rest where the anchor obstacle used to be. A detached ball can be pushed by touch, tears and explosions.

## Variants

### Found In

**Spikeballs** fly back and forth in a line either horizontally or vertically, bouncing off walls and obstacles. They will be destroyed once the room is cleared. However, if the room doesn't need clearing, they will remain permanently.

Spikeballs will be destroyed immediately upon entering a room while holding the .

### Found In

Exclusively spawned in Singe's boss room.

**Singe's Balls** are movable Spikeballs spawned during the Singe boss fight. They will not move on their own but can be pushed via touch, tears, and explosions- particularly Singe's. They deal half a heart of contact damage and are destroyed upon Singe's defeat.

## Trivia

* The Spikeball first appeared in the *Antibirth* mod where it behaved similarly however it would not be destroyed and would continue moving after the room was cleared.
Coil

**Coils** are indestructible spinal cord enemies found commonly in the Corpse chapter. They are immobile but can zap a constant laser at all enemies in the room (except for other Coils). Coils are often found in rooms containing other invincible enemies such as Wall Huggers or Spikeballs, making them a threat to the player even when the room is cleared. If there are no enemies in the room, Coils will become mostly harmless, though they can still do contact damage. If destroyed via Chaos Card, it will respawn if the player leaves and re-enters the room.

### Notes

* Coils' beams can target enemies frozen by Uranus or Freezer Baby.
Fatty

**Bubbles** are slightly bloated Fatties. They slowly walk towards Isaac, occasionally firing a tear at Isaac when damaged. They sometimes pause and fart, knocking back Isaac and other monsters, together with shooting a rapid burst of tears in random directions, each with a random range. Upon death, Bubbles bursts into a fountain of tears that rain down for several seconds.

### Quakey

The **Quakey** is a stone covered Fatty. It slowly walks towards Isaac. Sometimes it may leap a short distance. Upon landing, Isaac is knocked back, a ring of 8 rocks spreads from where it lands, and rocks will randomly fall from the ceiling.

### Big Bony

The **Big Bony** is a skeletal Fatty. It slowly walks towards Isaac. It occasionally fires a large explosive bone which creates rock waves near its point of impact.

### Barfy

The **Barfy** is a zombie Fatty. They slowly pace towards Isaac. They occasionally spew clusters of green shots towards Isaac, which leave puddles of damaging green creep.

### Vessel

The **Vessel** is a monstrous maggot-infested Fatty. It strolls towards Isaac, spawning a Small Maggot when it takes damage. Occasionally it stops to spew out even more Small Maggots along side an irregular puddle of damaging green creep around itself. Upon death it explodes into multiple Small Maggots.
Eraser

**Eraser** is an active item.

## Effects

* Upon use, Isaac will raise the eraser above his head. Upon pressing a fire button, the eraser will be thrown in the corresponding direction.
	+ Monsters of the same type as the one hit by the eraser will be prevented from appearing for the rest of the current run.

## Notes

* The smallest heads of Super Envy still spawn even if one of them was erased previously; only existing heads are affected.
* This item will kill bosses, but will not prevent them from showing up later in the run.
* The item does not work on Stone Grimace or any of its variants.

## Trivia

* When Eraser was ported into *Repentance*, it was changed to be usable once per floor. However, it now deals a flat 15 damage to bosses instead of instantly killing them, but can permanently erase bosses if it gets the kill.
Myosotis

Forget me not...

**Myosotis** is a trinket.

## Effects

* Spawns pickups left on the previous floor in the starting room of the current floor.
	+ A maximum of 8 pickups can be spawned.

## Notes

* If Isaac enters a trapdoor to the next floor and there were pickups in the room with the trapdoor, they will not be spawned on the next floor.

## Trivia

* Forget me not is a common name for the flower genus Myosotis.
Book Of Despair

**Book Of Despair** is an active item.

## Effects

* Halves tear delay for the current room.

## Trivia

* This item originated from the *Binding of Isaac: Community Remix* mod.
* Upon use, Isaac starts crying, similar to his appearance after picking up Torn Photo.
* Book Of Despair was one of the few items not imported into *Repentance*, alongside Bowl of Tears, Donkey Jawbone, Knife Piece 3, Menorah, Stone Bombs, and Voodoo Pin.

One Tooth

## Blind Bat

**Blind Bat** is an alternate version of One Tooth that starts out asleep. When Isaac gets close, it wakes up and chases Isaac, followed by a group of three more Blind Bats. Blind Bats will also wake up if a loud sound happens in the room, such as an explosion or a Quakey performing his ground smash attack.

## Echo Bat

**Echo Bat** is an alternate version of One Tooth that flies towards Isaac and periodically fires three white orbs. If an orb hits Isaac, he becomes confused and his movement is reversed for a few seconds.

## Trivia

* Blind Bats appear to be based off of Battons from the Mega Man series, as both start invulnerable and hanging from a ceiling with their wings closed and wake up, moving towards the player when they move close to their hanging positions.

## Effects

* Frequency of large rooms is greatly increased.
	+ Large rooms can be a combination of multiple regular rooms.

## Gallery

* A double-sized room made of 2 regular rooms.
* A quadruple-sized room made of 4 regular rooms.

## Bugs

 ****Bug!**** The Curse can break teleporters on the Mausoleum when the combined rooms share the same symbol on a teleporter. Under certain circumstances, this can render some rooms unclearable, or at least a section inaccessible.
Dirty Mind

**Dirty Mind** is a passive item.

## Effects

* Destroying poop spawns friendly Dips that follow the player and damage enemies.
	+ If the poop is destroyed by tears (or any other form of damage which does not destroy the poop in one hit), it will spawn Dips every time it is hit. Normally 2 or 3 Dips will spawn.
	+ If the poop is destroyed by explosions or stomping, it will always spawn 4 Dips.
* Different types of poop spawn different Dips:
	+ Corny poop spawns Corny Dips, which occasionally spawn blue flies.
	+ Red poop spawns Red Dips, which deal more damage but disappear after a short amount of time.
	+ Golden poop spawns Golden Dips, which inflict the effect of Midas' Touch and drop coins upon death.
	+ Rainbow poop spawns Rainbow Dips, which charm enemies they touch and drop Half Red Hearts upon death.
* All enemy Dips will be transformed into friendly Dips.
* Rocks and objects have a small chance to be turned into poop when generated.
	+ Angel and Devil statues may also be turned into poop.

## Notes

* There is a maximum number of Dips that can follow the player. Summoning more Dips will destroy old ones.

Corpse

**Corpse** is a new environment added in *Antibirth*.

Once all three knife pieces have been acquired, upon completing Mausoleum II, a red fleshy door will appear. On subsequent runs, this door will appear regardless of whether or not you have all three knife pieces. Stabbing the door with the knife or throwing Sharp Key at it will open it, leading to a more difficult variant of Mom's Heart. After defeating Mom's Heart, the trapdoor previously leading to the Womb will now lead to the Corpse.

120 Volt

**120 Volt** is a passive item.

## Effects

* Whenever an enemy is shot, it will zap other enemies near them, dealing damage.
	+ Enemies that are zapped can also zap nearby enemies.
	+ The zaps transfer tear effects.

## Synergies

* Lodestone - The magnetizing effect is spread via 120 Volt, resulting in a dense mass of enemies that further attracts the players' shots.
* Brimstone - The laser turns light blue and zaps enemies.
* Technology - The laser turns blue and creates arcs to other enemies.

## Interactions

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

## Trivia

* The *Community Remix* mod has a 'Box of Wires' item which makes Isaac shoot electricity tears, probably an inspiration for this item as its pickup quote is "Zap zap!"
* In *Repentance*, this item was reworked to instead rapidly zap enemies near Isaac. Its *Antibirth* effect was partially moved to the existing item Jacob's Ladder.

The pack allows for some items to be won permanently-however, these are limited to primary and secondary weapon receivers.
Eternal D6

Defeat The Witness as ???.

**Eternal D6** is an active item.

## Effects

* Rerolls an item like the D6, but the rerolled item has a chance to disappear.

## Notes

* When rerolling multiple item pedestals, the chance for an item to disappear is rolled individually for each pedestal.

## Trivia

* This item is a reference to the behavior of the D6 in The Binding of Isaac: Eternal Edition's hard mode.
* When Eternal D6 was ported into *Repentance*, its charge time was lowered to 2.
R Key

## Effects

* Upon use, restarts the game to the first floor, keeping all previously collected items. The game timer does not restart. Allows angels rooms to be found even if the previous run included devil deals.
* Does *not* heal Isaac on use, so be careful.

## Notes

* R Key changes the map of previous floors, while the current floor's layout remains the same.
* Using R Key will not prevent Magic Skin from showing up if it has been used before.
* R Key can be used on The Chest or Dark Room to completely restart a run and get even more items.

## Gallery

* Concept art for Antibirth items, including R Key.

## Trivia

* The *R Key* is a reference to the fact that you can quickly start a new run by holding down the R button.
Screamer

**Screamers** are tall, grey enemies that slowly move around the room. If Isaac gets too close to one, it will scream, paralyzing Isaac.

After it screams, its speed will drastically increase, and it will try to chase Isaac down. It will also gain a black aura around itself that will slow Isaac down if he's within it.

## Notes

* It is recommended to kill this enemy at a distance to avoid angering it.
* It is possible to trigger its scream without being paralyzed, provided Isaac has enough speed to move out of its radius.

## Trivia

* Screamers appear to be based on the ReDead enemies from *The Legend of Zelda*, who are also tall, skinny enemies with a paralyzing scream.
Dip

## Hardy

**Hardy** is an alternate version of Squirt. It charges at the player until it runs into a wall or obstacle. Upon impacting a wall or obstacle (besides gaps), 8 rock projectiles are fired in all directions. On the second and third impact, Hardies will additionally shoot a chaotic cluster of stone projectiles in the direction they were charging. After three impacts, Hardies will break themselves open, causing rocks to fall from the ceiling, some of which may be Rock Spiders. Hardies spawn a Dip upon death. If a Hardy impacts a rock or a door, those obstacles will break open.
Reap Creep

**Reap Creep** is one of the bosses that can appear in **Chapter 3**.

## Behavior

Reap Creep crawls back and forth along the upper wall of the room and will have different attacks depending on the rotation of his face. Each face has its health pool and must be defeated before the next phase activates.

* If his upper face has an open eye, he will spawn Wall Creeps and fire streams of bullets towards Isaac.
* If his upper face has a closed X eye, he will spawn Trites or Big Spiders and shoot blood tears in wide-spread bursts, which can be one of the following:
	+ A disorganized burst similar to Monstro's main attack.
	+ A wide, organized fan of tears, in a semi-circular pattern.
	+ Fires tears with a boomerang effect (similar to My Reflection) if Isaac is on one of his sides.
* If his upper face has an empty hole, he will ram the walls, sending down falling rocks occasionally containing Rock Spiders if fought in the Mines or normal Spiders if fought in Rebirth chapters. He will also fire large Brimstone lasers. These appear in two patterns, which can be determined by the amount of time he spends charging.
	+ One is a very wide beam directly forwards, which has a short charge time.
	+ The other is a fan of four normal-sized beams that start at wide angles, then close together to force Isaac to stand directly in front of the boss. This attack can be anticipated through its much longer charge time.

* Concept Art For Reap Creep's Second Phase (Blind Creep)

## Trivia

* Reap Creep started as a versus screen mockup by Antibirth artist NotYourSagittarius in January 2015, alongside The Visage and a posthumous version of Dingle.
* Reap Creep, like several other bosses introduced in Antibirth, is based off of a group of common monsters encountered on the various floors. The Reap Creep, as the name suggests, is based off of the Creep enemies.
* Like all Creep enemies, the Reap Creep has an appearance similar to a spider, crawls along a single wall, fires shots from its mouth, and has different behavior based on the appearance of its eye.
* The first phase is similar to a Wall Creep. Like the monster, this phase has a relatively normal eye and is based on firing short bursts of tears directly at Isaac.
* The second phase mimics a Blind Creep, bearing a similar crossed out eye and choosing a spread outshot pattern instead of a precise one.
* The third and final phase behaves like a Rage Creep, sharing the empty eye socket seen on the monster as well as the use of Brimstone lasers as the primary method of attack. The attack used by this phase where Reap Creep slams into the walls of the room may also be a reference to the monster's name, as this behavior seems to suggest that the boss is throwing a tantrum.

Blessed Penny

Wealth of purity

**Blessed Penny** is a trinket.

## Effects

* Adds a chance to spawn half a soul heart when picking up a coin.

## Notes

* Picking up nickels and dimes can spawn multiple half soul hearts.

## Trivia

fr:Blessed Penny
The Pile

**The Pile** is one of the bosses that can appear in **Chapter 3**.

## Behavior

* Pops out of the ground near the player 3 times and throws 5 bones each time.
* Summons waves of spikes in the cardinal directions.
* Charges towards the player at high speed. Upon colliding with a wall, bone projectiles and rock waves are sent in all directions.
* Spawns Bonies.

## Trivia

* The Pile is a posthumous form of Polycephalus, similar to The Stain added in Afterbirth.
	+ Despite the fact that The Stain was already in the game, the Pile was also added into Repentance, meaning Polycephalus has two posthumous forms.
* A third skull can be seen in the background of The Pile's boss art.
* Antibirth's artist, NotYourSagittarius, first posted a versus screen of this boss and then a full mockup in the Isaac subreddit both in January 2015, which was implemented by antibirth's developer Kilburn into a mod during the same month.

Spikeball

**Spikeballs** are a common hazard located in the Corpse. They float back and forth on a fixed axis either horizontally or vertically, doing contact damage. Only rocks, the edges of the room, and other Spikeballs can obstruct their path and make them turn the other way; however, gaps and spikes will just be flown over. Spikeballs can not be killed and will continue to move even if the room is cleared.
Death's Head

## Smoky

**Smoky** is an alternate version of Death's Head that bounces around the room with a purple aura. If Isaac touches an aura, he will briefly become afraid, unable to fire tears for a short period. It dies when the room is cleared.

## Trivia

Smokys are a reference to Blue Bubblesfrom The Legend of Zelda, wherein some of the games Blue Bubbles curse the player, making them unable to attack or use items.
Bosses

**Bosses** are strong monsters found in boss rooms at the end of a floor. The boss at the end of the floor must be defeated to advance to the next floor. The boss for a particular floor is chosen from the pool of bosses for the environment of the floor. Upon defeat, most bosses will drop an item from the boss item pool.

*Antibirth* adds 16 new bosses and a few variants on existing bosses.

## Universal

These bosses have a chance of replacing a boss from an environment pool, including Antibirth floors.
The Siren

**The Siren** is one of the bosses that can appear in **Mausoleum**.

## Behavior

* Creates a large red aura around herself, then begins to fire rings of bullets which have openings in Isaac's direction. These bullets split when they leave the aura.
* Sings, charming your familiars and turning them against you. You can cancel this by attacking them.
* Fires music notes in hexagonal directions, which at first travel in a straight line away from her, but then begin to curve either to the left or right.
* Spawns 3 Incubus-like familiars which rotate around her, occasionally firing tears at Isaac.
* Phases into the ground and chases Isaac, leaving a trail of creep.
* Pulls their arm back before launching herself forward in an attempt to slap you.

## Notes

* Her ability to charm familiars can be frustrating if the player has Dead Cat, because if she is defeated while it is charmed she'll revive with 10% health, stealing one life of the Dead Cat in the process.
	+ Other familiars that give more lives to the player will also revive her.
* After the battle is over, The Siren's skull will lie on the floor. Breaking the skull will unlock the Song of the Siren.
* Having the Dry Baby will make it harder to kill her due to its Necronomicon effect.

## Trivia

* Sirens are monsters found mostly in Greek mythology and are usually portrayed as women with the bodies of birds or fish. They would roost near shallow rocks and sing their hypnotizing song, trying to lure sailors to their doom.
* Her "ring" attack in which tears emit from her and split once far away is almost identical to that of the Gorgun's, a boss from the game Enter the Gungeon.
	+ Her chasing attack is also identical to another one of the Gorgun's attacks.
	+ The Siren's skull also resembles the Gorgun's petrified body. Since breaking them will unlock an item.
* The Siren was not in the initial version of Antibirth but was patched in about a day after release.
* The Siren is the only boss in the Mausoleum that is not based on another preexisting boss, and appears to be the boss that is not undead.

The Rainmaker

**The Rainmaker** is a boss that appears in Downpour.

## Behavior

The Rainmaker has three attacks:

* Pirouettes around, raising tears from the water below, which float for a while then shoot towards Isaac. Attack ends with The Rainmaker posing, sending 8 tears flying in cardinal and diagonal directions.
* Takes some of the water and forms it into a big ball above him, and then claps to make it explode, splashing the area around him with tears.
* Raises twelve tears in a line, six to his left and six to his right, which he sends towards Isaac after a delay, beginning with the outermost tears.

## Trivia

* During the fight, the rain will fall from the ceiling in random spots. However, this is purely aesthetic. The rain and the sound stops when the Rainmaker is defeated.
* Although his name and his elemental theme is a reference to rain dances, his movements are more akin to the dance moves of the modern period, such as those seen in flamenco.
* With his movements of dance, the rose in some of his animations and his versus screen, as well as even in his death animation, the Rainmaker's origin of inspiration may hint at the idea of theatre performance. Even the name of "Rainmaker" could hint at how his performances could make audiences cry.
* The Rainmaker's sounds are borrowed from Loki
* His appearance is similar to the enemy Polty.
* He is gay (source https://twitter.com/edmundmcmillen/status/1321662651055796224)
