Para-Bite

### Found In

The **Para-Bite** is a monster introduced in the vanilla content of *The Binding of Isaac: Rebirth*. They can be only encountered in Chapter 4.

It will move around the room until Isaac appears in its line of sight, prompting it to charge towards him and can deal a full heart of contact damage. They're also able to move underground and pop up in a different location, although they cannot spawn right under Isaac.

Chance to replace Para-Bites in the Scarred Womb

**Scarred Para-Bites** are a variant of Para-Bites added in *The Binding of Isaac: Afterbirth* DLC.

They behave similarly to regular Para-Bites and occasionally fire a short-ranged blood shot towards Isaac.

#### Notes

* Pure Magenta Champion Scarred Para-Bites will shoot two blood shots at different intervals.

## Trivia

* The Para-Bite first appear in the original Flash version of *The Binding of Isaac*.
* The name Para-Bite is a portmanteau of the words parasite and bite, with parasite meaning an organism that lives in or on another organism and benefits from it at the host's expense.
* The Para-Bite's sprite was based off of a character from an old comic Edmund made, whose name was Longits.
* The attack pattern of the Para-Bite was based off of an enemy in the Zelda series.
Ring Cap

**Ring Cap** is an unlockable trinket added in *The Binding of Isaac: Repentance*.

## Effects

* Places one extra Bomb for each bomb placed free of charge.

## Notes

* The extra bomb is spawned in a random location next to the original bomb placed.
* The additional bomb is affected by any items that affect bombs.
* Ring Cap will also work with Giga Bombs collected via .
* Can be used to open the door to the Mines / Ashpit with only one bomb.
* This trinket has no effect on the Explosive Diarrhea pill.

## Synergies

* Golden Trinket /  / : Each effect/trinket copy stacks placing 1 extra bomb per stack.
* : Grants a random bomb effect to each bomb separately.
* : Fires two rockets simultaneously.

## No Effect

* Tainted ???
Prayer Card

**Prayer Card** is an activated item.

## Effects

* Gives an Eternal Heart upon activation.

## Notes

* If used after clearing a floor, before proceeding to the next one, it guarantees a new Heart Container every floor.
* Since it adds the eternal heart directly to the health bar instead of spawning it on the floor, the item is useless for  Keeper.

## Synergies

* : Spawns white, heart-shaped wisps in the inner ring. Wisps' tears have 0.75 shot speed. The wisps' tears effectively act as though they have .
	+ The wisps have two possible sizes. The bigger ones seem to spawn if using Prayer Card gives Isaac another Heart Container.
* : Grants one full Heart Container upon use.
* Tainted Eden: Health ups granted by eternal hearts are not rerolled when Tainted Eden takes damage.

## Interactions

* Tainted Magdalene: Doesn't benefit from her passive ability, giving only 1 Eternal Heart as usual.

## Gallery

* 3DS The icon of Prayer Card as seen on the lower 3DS screen

## Trivia

* In the Christian tradition, holy cards or prayer cards are small, devotional pictures mass-produced for the use of the faithful. They usually depict a religious scene or a saint in an image about the size of a playing card. The opposite side typically contains a prayer, some of which promise an indulgence for its recitation.
* The design on the Prayer Card appears to be of the painting Our Lady of Guadalupe.
Lost Contact

**Lost Contact** is a passive item.

## Effects

* Gives Isaac's tears a shield surrounding them, allowing the player to block enemy shots.
	+ Isaac's shots are destroyed upon contact with an enemy's shot.
	+ Affects familiar's tears.
* -0.15 shot speed.

## Synergies

* : Placing many tears around Isaac creates a safe zone, especially with larger tears.
* ///: Beam/ring/laser destroys projectiles, although only during its damage tick interval. The projectiles are not instantly destroyed when they touch the beam/ring/laser.
* //: Split tears will be shielded. The Parasite's split tears will not appear to have shields.
* : Piercing through a projectile will trigger Eye of Belial's double damage and homing effect. Belial tears will still block shots.
* The Forgotten: Enemy shots may be reflected with melee attacks. The damage of the reflected shots depends on their size and properties, with standard enemy shots dealing 6 damage, champion and homing shots dealing 7 and explosive ones dealing 50.
* : Destroyed tears via shot-blocking will trigger the electric arc effect.
* : Can block an infinite amount of enemy shots if the tear is placed on top of a monster. The projectiles that they attempt to shoot will be immediately destroyed.
* : The knife will destroy projectiles in its path without being affected.
	+ The knife does not destroy projectiles.
* Piercing tears: The tears can pass through multiple enemy projectiles. This means that one tear can hurt the enemy and block its projectiles.
* : Enemy shots are treated like enemies with 10 health, which are deducted from the Polyphemus tear. If it has strength remaining afterward, it will continue.
* /: Tears that stick to enemies will block shots, and will not be destroyed in the process.
* : The constant stream of tears will cut through any complex attack patterns with ease.
* : Sword swings reflect projectiles.
* : The random tear effects can allow more shots to be blocked, as effects such as , , and  can cause tears to wander outside of the main stream of tears. However, this, in combination with the lower fire rate of Almond Milk compared to Soy Milk, makes Almond Milk slightly less effective than Soy Milk at blocking shots in the direction Isaac is shooting.
* : The rings block enemy shots.
	+ The rings sometimes block enemy shots. [more testing/debugging required]
* : Beams will block shots and continue on.

## Interactions

* : Bombs will not destroy or block shots. Stat effects apply.
* : Missiles will not destroy or block shots. Stat effects apply.
* : Lost Contact will remove the chance to explode on impact effect.
* : Tears with the shrink effect do not appear to be shielded, but will still block enemy shots.
* : Auras will not block shots but tears will.
* : Main tears will block shots but burst tears cannot.
* : Ipecac shot will explode upon contact with an enemy's shot.
* : Tears often block shots before they can burst; however, burst tears can also block shots.
* : The stone will not block shots.
* : Overridden by Lost Contact.
* : Tears will bounce off of enemy tears and destroy them.
* : Teeth will not appear to be shielded but will still block enemy shots.
Mom's Eye

**Mom's Eye** is a passive item.

## Effect

* Gives Isaac a chance to shoot a tear out of an eye on the back of his head.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into his mother.

## Notes

* The chance to shoot an extra tear depends on the luck stat, and the formula used to determine the chance is:

1

2
−

⌊

L
u
c
k

∗
0.5

⌋

{\displaystyle \frac1 { 2 - \left \lfloor \mathit{Luck} \* 0.5 \right \rfloor}}

	+ At base luck (0), the chance is 50%, maxing out at 100% at 2 luck.
* The chance to shoot an extra tear depends on the luck stat and is based on this formula:

50
%
(
10
%
∗

L
u
c
k

)

{\displaystyle 50\% + (10\% \* \mathit{Luck})}

	+ This means that the chance starts at 50% at 0 luck, minimizes at 0% at -5 luck, and maximizes at 100% at 5 luck.

## Synergies

* : Tears shot out of the back reappear on the opposite side of the screen.
* : Mom's Eye tears follow the direction in which Isaac is shooting.
* : Any time Mom's Eye would activate, Loki's Horns activates instead.
* : Tears bounce around, making the backward tear more likely to hit enemies.
* : Another knife is permanently behind Isaac, able to deal contact damage. The fire chance is still affected by luck as usual.

## Interactions

* //: No effect on the tears fired out of the back of Isaac's head. The chance to activate is checked per shot, not for each tear fired.
* : Occasionally shoots a bomb backward. Not recommended, as self-damage is likely.
* /: Chance for two airstrikes on opposite sides of Isaac.
* : Occasionally shoots an explosive shot backward. Not recommended, as self-damage is likely.
* : No effect.
* : Adds a chance for each tear from the barrage to fire from the front and back of Isaac. The kidney stone will only fire from the front of Isaac.
* : Adds a chance for the tear barrage to be fired behind Isaac instead of in front.
* : Adds a chance for piercing + spectral tears to be fired in random directions from the main tear. This chance scales with luck and goes up to 100% at 10 Luck.
* : Occasionally fires one red tear out the back of Isaac's head.
* : The backward tear is not affected by Tractor Beam.
* : The backward tear is not affected by The Wiz.

## Trivia

* Mom's Eye's appearance was changed in Booster Pack#5.
* The item is based on the adage that a mother has an eye on the back of her head, and is thus always able to see what her child is up to.

Nancy Bombs

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

## Effects

* Grants 5 Bombs.
* Causes Isaac's bombs to gain the effects of 1-4 random bomb synergies (most commonly 1).
	+ Aside from normal bomb synergy items, this also includes , , and Golden Bombs (golden bombs will not be free).

## Notes

* Nancy Bombs cannot give the effects of , , or Giga Bombs.
* Even though Nancy Bombs can grant the  synergy, this will have no effect on the bomb placement speed. It will, however, disallow that bomb to knock back other bombs.

## Interactions

* / : Bombs have a chance to be affected by Nancy Bombs.
* : Gains the effect of a random bomb synergy each time it is used.
* : Extra bombs will copy the bomb synergies of the original bomb.
* : Turns into  when rerolled.

## Trivia

* This item originated in the Community Remix mod for the original *Binding of Isaac*, where it was known as Enigma Bombs. The item reappeared in *Antibirth*, where it went by its original name; the rename was likely to match the naming scheme of , , and .
	+ "Nancy" as a pejorative term refers to an effeminate male.
Quints

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

## Effects

* Upon killing enemies, spawns a stationary familiar in their place for the room, up to a maximum of 5. These familiars do not follow Isaac.
* The following familiars can spawn:
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a three-faced version of himself.

## Notes

* Killing the heads thrown by Rag Man before they turn into a Rag Man's Ragling is not counted as a kill and will not spawn a baby.
* Getting hit by an enemy and Spawning a Baby from the same enemy at the same time crashes the game.
* The same familiar can spawn multiple times.
* Despite being stationary, tear-shooting babies will still inherit Isaac's movement, angling their tears accordingly.
* Enemies killed by Dark Esau count as yours and will spawn a baby.
* During The Beast fight, familiars spawned by Quints stay on screen throughout the chase sequence.
* When playing as  Tainted Lazarus, Quints will not disappear on  but instead give you the ability to spawn more Quints if you Flip again. This is very effective in Greed mode and Boss rush because you flip automatically when completing a wave, giving you more Quints for every other wave.

## Interactions

* Ace Cards: Enemies that are turned into pickups don’t leave familiars behind.
* : All shooting familiars spawned are affected, save for Little Steven and Seraphim.
* : Affects Quints familiars, doubling their damage.
* : Existing Quints familiars will not be duplicated, nor more will be created. If Isaac has no other familiars, the generated Demon Baby will hover with the Quints instead of following Isaac.
* /: Enemies that are turned into poop don't leave familiars behind.
* : Familiars do not follow King Baby, nor are the familiars aiming independently at enemies.
* : Lets you spawn an additional 5 Quints familiars per copy.
* : The item will be lost, and each spawned familiar counts as one sacrifice. If Quints is sacrificed first (or is the only item available to sacrifice) and at least two familiars are summoned, two Devil Room items will be spawned while only losing one item.

## Trivia

* The name of this item is a shortened form of "Quintuplets," or five babies born at the same time. This is likely why it can create up to 5 familiars.
* The name may be a reference to chan image board posts where the posters try to claim "quints" (5 consecutive numbers) in a post ID. Chan users are often referred to as lurkers.
Rainbow Baby

**Rainbow Baby** is a passive item.

## Effect

* Spawns a familiar that follows Isaac around and fires tears with random effects similar to other familiars.
	+ Rainbow Baby shoots once per second.
	+ Rainbow Baby shoots 1.36 times a second.
* The shot types and their damage are:
	+ Short-range blood tear for 3 damage.

	+ Long-range homing violet tear for 3.5 damage.
	+ Long-range spectral and homing tear for 3.5 damage.
	+ Blood tear for 4 damage.
	+ Large blood tear for 5 damage.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a three-faced version of himself.

## Notes

* Familiars that follow behind Isaac have a certain priority in how close their position is to him over other familiars, with Rainbow Baby having 5th priority.

## Synergies

* : Will copy Rainbow Baby’s random tears.

## Interactions

* : The randomization of tears shot by multiple Rainbow Babies are not in sync.

## Trivia

* This item is used in  PRIDE DAY! (challenge #28).
* A rainbow baby is a healthy baby born to a family that had previously experienced the loss of an infant before, during, or shortly after birth.
* In the *Wrath of the Lamb* DLC for the original game, this item was unlocked by beating Isaac as  ???.
Mom's Hand

### Found In

**Mom's Hands** are tricky foes. When these enemies spawn (either at the start of a room or in a Challenge Room wave), Mom's laugh can be heard  and the ground may shake. After this, a disembodied hand will come down to try and grab Isaac, pausing in a stunned state for a brief moment before going back up to repeat this. Before coming down, a subtle shadow on the floor will indicate where the hand is going to land. They can spawn in groups of up to six in large rooms.

If Isaac is grabbed, he takes half a heart of damage and is sent back to the spawn room of the floor. Any enemies that Isaac damaged or killed before being grabbed will respawn at full health when Isaac returns to the room. If a black heart is depleted when Isaac is grabbed, he will not be teleported and the hand will die instead.

Charmed Mom's Hands are extremely powerful, as they can potentially kill any monster they attack in a single move if they manage to grab them and pull them up without getting killed in the process. This includes normally invincible enemies such as Stone Grimaces. This can be seen more easily by using the "C0CK FGHT" Special Seed.

## Mom's Dead Hand

### Found In

**Mom's Dead Hands** behave similarly to regular Mom's Hands. When they land, they send out 3-4 lines of rock waves in the cardinal directions that can curve slightly and will destroy most obstacles and damage most monsters in its path. Upon death, they spawn 2-3 Spiders. Unlike normal Mom's Hands, they can't grab and teleport Isaac.

## Gallery

* Sketches of monsters for the Binding of Isaac: Rebirth, including Mom's Hand in the sixth square of the second row.

## Notes

* The rock waves that Mom's Dead Hands spawn can open Secret Rooms and Super Secret Rooms.

## Trivia

* The Hands are likely inspired by Wallmasters from the *The Legend of Zelda*.
* If Mom's Hand catches Isaac in a Challenge Room, it will teleport him out of the room without having to fight the remaining enemy waves, even if the room is re-entered.
* Mom's Hand is the only enemy in the game that can teleport Isaac to a different room.
* card spawns two Mom's Hands that grab enemies.
Purple Heart

**Purple Heart** is a trinket.

## Effects

* Doubles the chance for champion enemies to appear.
* Also increases the chance of encountering champion bosses.

## Notes

* The increased number of Champions means that more enemies will drop additional loot, which can be useful when low on keys or bombs.
* The chance to spawn a champion in Normal is very low (5%), and the drop chance for additional loot in Hard mode is only 33%, making this trinket very rarely worth keeping.
* Since champions don't drop any consumables in Greed Mode, this trinket only has a downside in this mode.

## Synergies

* Golden Trinket / : Each copy of Purple Heart increases the multiplier by 2 (e.g. 6x with 3 Purple Hearts, 20x with 10 Purple Hearts).
	+ Holding multiple Purple Hearts doesn't increase champion chance.

## Trivia

* The Purple Heart is a military decoration awarded to soldiers who are wounded or killed while serving in the U.S. Military.
Oh Crap

Upon picking up 3 poop items from the following list ( 3 items with the `poop` item tag), Isaac will heal half of a red heart each time a pile of poop is destroyed.

## Activated Collectibles

 Brown Nugget | 5.100.504

## Notes

* Despite being poop-themed, , , and  do not count towards the transformation.
* Despite being poop-themed,  does not count towards the transformation.
* Poop created with  and  do not heal Isaac when he has this transformation.
* Oh Crap! is useless for any character that cannot have Red Heart Containers such as  ???,  The Lost,  Dark Judas,  Keeper,  Tainted ???,  Tainted Keeper,  Tainted Judas, and  Tainted Lost.
	+ Tainted Bethany will get blood charges for destroying poops.
* The Scat Man and High Brow challenges start with this transformation.

Peep deals a whole heart of contact damage.

## Champion Versions

**Cyan**: Starts the battle with both his eyes popped out, similar to The Bloat.
**Yellow**: 15% smaller, moves faster, and leaves a constant trail of Yellow Creep.

* His posthumous version is The Bloat.
* He has 3 unused sprites in his spritesheet that were removed in The Bloat spritesheet.
* Yellow Peep's pupils diverge slightly, resembling .
RERUN

**RERUN** is a menu option in added in Afterbirth †, unlocked after completing  **RERUN** (Unlocked by completing 3 Victory Laps in a row and starting the fourth).

After winning a run, the *Continue* option in the main menu will be replaced by *RERUN*. Selecting it starts a new run using most of the previous won run's items.

## Notes

* Isaac will take full heart damage on all floors, except in Greed Mode.
* It may not be necessary to start a 4th lap to complete the achievement on some versions/platforms. Even if an extra lap is started, it may be quit immediately.
* RERUN cannot be used multiple times in a row. After beating a RERUN, the main menu option becomes *Continue* again.
	+ The run with the last character can be relaunched only via defeating The Lamb and starting Victory Lap.
	+ After ending a Victory Lap in any way, the option in the menu is still *Continue.*
* RERUN is not counted into the win streak.
* Achievements are disabled for RERUN.
	+ As achievements are disabled, the Donation Machine will not spawn.
	+ This applies to Greed Mode runs started by RERUN as well, with the Greed Donation Machine not appearing after defeating Ultra Greed.
Rainbow Worm

**Rainbow Worm** is a trinket added in *The Binding of Isaac: Afterbirth*.

## Effects

* Isaac's tears gain a worm trinket effect that changes every 3 seconds of the in-game timer. The effects include:
* The order of the effects is always as above, in a cycle.

## Notes

* Rainbow Worm can't give the effects of worms that are already in effect (with  or ) or ones that were gulped.
	+ Therefore, somehow gulping all the worm trinkets in one run makes Rainbow Worm useless.
	+ Rainbow Worm acts as giving a second copy of worms you're currently holding, usually doubling any stat increases of the worm.

## Synergies

* Golden Trinket /  /  : Doubles the effect of each worm.
* : The altered patterns tears travel in is confined to the beam allowing Isaac to benefit from the stat bonuses granted without losing accuracy.

## Trivia

* This trinket is used in Challenge #28 (PRIDE DAY!).

* Papa Fly's tears deal Isaac's damage, and are fired once per second.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a giant humanoid fly.

## Notes

* Since Papa Fly's damage scales off of Isaac's own damage, any item that provides a massive damage increase (such as  or ) will prove benefitial.

## Synergies

* : Papa Fly will always shoot two shots due to both of them having the same movement delay.
PJs

### Collection Grid

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

* This item belongs to the  set. Collecting three items from this set will transform Isaac into a walking mushroom.

## Notes

* There are two collectible items in the game named Odd Mushroom; they can be told them apart from the sprites.
* This item's damage multiplier works differently than other items in the game: instead of directly multiplying the damage stat, it multiplies the total added damage from other items. As a result, flat damage upgrades aren't affected by Odd Mushroom.
	+ Multiple copies of the item will grant a speed and fire rate boost with no additional decrease in damage.
* Isaac's head becomes smaller as a result of this item. This is purely cosmetic.

## Notes

* Bad pills already obtained/dropped will be converted to their "good" counterparts.
* If PHD is lost in any way, such as rerolling by the  or a Dice Room, or dropping it as  Tainted Isaac, pills will remain fully identified, but negative pills will not be converted.
* Performing a RERUN with a character that held PHD will still prevent negative pills from spawning, but will no longer identify pills until used.
* As bad pills will turn into good pills, it is possible for two different colored pills to have the same effect.
* Multiple copies of PHD will not yield more coins when using a Blood Donation Machine or IV Bag.

## Interactions

* : Pills can both be good or bad again. Taking a bad pill still applies the benefits from False PHD.
* Keeper /  Tainted Keeper: Blood Donation Machines will not produce more coins and they will still have a chance to fail.

## Trivia

* PHD stands for Doctor of Philosophy (Ph.D.) and it's the most common degree at the highest academic level awarded following a course of study. Doctorates can be in any study, in Isaac's case, medicine.

Poot Mine

### Found In

**Poot Mines** are an enemy added in *The Binding of Isaac: Repentance*. They are encountered only in Dross.

Ouroboros Worm

**Ouroboros Worm** is a trinket added in *The Binding of Isaac: Afterbirth †*.

## Effects

* Tears travel in a large spiral pattern.
* Grants spectral tears.
* +4.0 range.
	+ +1.5 range, +0.4 tears.
* +2.0 tear falling speed.
* A luck-based chance for a homing shot, reaching 100% at 9 luck.
	+ The homing shots are not different in appearance.
	+ The homing does not override the spiral pattern, meaning tears stay unreliable.

## Synergies

* : Creep has a chance to be homing.

* : Since the bombs don't follow the spiral pattern, only the extra range, spectral bombs, and chance for a homing bomb apply.
* : The tears follow a straight path, ignoring the spiral pattern; the tears also stall at a specific point, giving a greater chance to land tears.

## Interactions

* Azazel: Increases the range of his short-ranged Brimstone. No homing chance.
	+ His Brimstone now spins.
* : Overrides Ouroboros Worm.
	+ The Brimstone laser is shot in a spiral pattern. Homing does take effect, but is hardly noticeable.
* : The tear spirals around in a difficult to control manner, with the added homing chance further complicating things.
* : Overrides Ouroboros Worm.
	+ Works as intended. The homing, however, is questionable.
* : The curious pattern allows dealing full damage from a safer range.
* Tainted Azazel: His Brimstone laser is shot in a spiral pattern. Homing does take effect, but is hardly noticeable.
* : Overrides Ouroboros Worm.
	+ Tech X now inherits the homing chance benefit, without being affected by the pattern.
* : Grants spectral tears without a change in pattern or a chance of homing shots.
	+ The tech laser is now affected by the pattern. The homing DOES take affect, but it's fairly hard to notice.

Tainted Pooters are corrupt and much tankier versions of Pooters. They move the same as Pooters, slowly drifting towards Isaac, however instead of firing just one blood shot at him, they shoot 4 big shots that become 2 smaller ones when in contact with a wall or obstacle.

* Found inside of Chests.
* Dropped by any kind of Beggar.
* Found after blasting Tinted Rocks.
* Dropped by various Slot Machines.
* Bought in Shops.
* Generated as part of an item effect.

## Notes

* Most of the pickups that a player gets on a run will be from clearing rooms. For the logic involved in this, see Room Clear Awards.
* When the "KEEP AWAY" seed is enabled, all pickups will mimic Isaac's movements.
* When the "GONE SOON" seed is enabled, all pickups will quickly fade.
* When the "CAMO DROP" seed is enabled, all pickups (and items) will blend into the ground.
Mega Maw

Degraded Boss

**Mega Maw** is a boss that can appear:

* Only in the Caves.
* In the Caves and the Flooded Caves.

## Behavior

Mega Maw is stationary and will perform the following attacks:

* Fires red projectiles at Isaac in disorganized bursts, similar to Monstro.
* Releases 2 rings of 5 flames which expand outwards and rotate in opposite directions.
* Releases one large ring of 9 flames that expands outwards.
* Releases one large ring of 9 flames that can rotate in either direction while expanding outwards.
* Gradually spits out a Hopper directly below it.

## Champion Versions

 **Black**: Spits 1-2 Spiders instead of Hoppers. The Spiders will be tossed directly towards Isaac instead of landing below Mega Maw. It does not use flame attacks.
 **Red**: Doesn't shoot any flames or spawn monsters and has a completely different set of blood-shot attacks:
Fires a ring of 9 blood shots that spiral outward.
Fires 4-5 lines of 4 curving blood shots.
Fires 4 lines of 7 waving blood shots.
Fires 10 lines of 4 blood shots in all directions.
All the attacks of the Red version do 1 heart of damage.
## Gallery

* Mega Maw in-game.
* Black Champion Mega Maw.
* Red Champion Mega Maw.
* Mega Maw as one of  Delirium's forms.
* Concept art for Mega Maw (known in this sketch as "Mr. Maw Mega"), along with a scrapped variant of Pin and what is presumably an earlier version of The Gate.

## Trivia

* It is the boss version of the Maws.
* The Gate is the posthumous version of it.
* Before its fire attack, a purple flame can be seen emanating from its forehead.
* Despite its name, it acts and looks more like a Horf (or a Psychic Horf) than a Maw, because it does not move and its eyes are more round.
* Its fire attack could be a reference to *Mega Man's* leaf shield/attack.
* The visual appearance of the Red Champion version may be a reference to the  item.
Redemption

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

## Effects

* Upon entering a Devil Room, a white inverted cross will appear above Isaac's head. If Isaac goes to the next floor with the icon still above his head, he will gain a Soul Heart and +1.0 damage.
* Taking anything generated by the room (items or consumables) will result in the icon going away.
	+ Opening Red Chests will also make the icon go away.
		- However, getting an item from a Red Chest will keep the icon.
		- Opening Red Chests that have been spawned after room generation, e.g. as a room clear reward or enemy drop, won't remove the icon.
	+ Taking  or  after Krampus fight will keep the icon.

## Notes

* After Isaac has taken a Devil Deal, while a Confessional or Sacrifice Room would give an Angel Room item, it has a higher chance to spawn Redemption instead. This is the only way Redemption can be naturally generated during a run.
	+ Other reliable ways includes using , or using  on .
	+ Redemption has a small chance to be a starting item as  Eden,  Tainted Eden, or any character with .
	+ Using  as  Eden has a small chance to spawn Redemption.
	+ If  was taken after taking a Devil Deal, Redemption is not guaranteed to spawn.
* Picking up items made free through usage of items such as Coupon or a Credit Card will still remove the icon and provide no benefit.
	+ However picking up a free active item and swapping it with one you have will not affect the icon.
* Taking pickups dropped by Fire Places will not remove the cross.
* Taking items inside the Devil Room spawned by Devil Beggars will not remove the cross.
* Taking items from a Black Market or  affected Shop will not remove the cross.
* Taking the boss's item when it's affected by  will remove the cross however the Boss Room can't give the cross.
* When playing as  Tainted Lazarus, the holder must enter the Devil room to trigger the cross; it will not work if you transform inside. The character with the inverted cross must be the one to travel to the next floor.
* When playing as  Jacob and Esau, the cross won't disappear if the character without redemption takes the items/loot in the devil room.

## Interactions

* : Devil Treasure Rooms will count as regular Devil Rooms for the purposes of this item.

## Trivia

* The pickup quote is taken from the last verse of the Lord's Prayer: "And lead us not into temptation, but deliver us from evil.'"
Potato Peeler

**Potato Peeler** is an activated item added in *The Binding of Isaac: Afterbirth †*.

## Effects

* On use:
	+ Removes one Red Heart Container.
	+ Increases damage by a flat +0.2.
	+ Grants one .
		- The Cube of Meat is not added as a real item in Isaac's inventory.
	+ Grants an active  effect for the current room.
	+ Counts as self-damage for the purposes of damage-triggered items.

## Notes

* It is possible for Isaac to kill himself by removing his final heart container.
* It is possible to generate multiple Meat Boys.
* Cubes of Meat given by this item do not remove any Cubes of Meat from Greed Mode item pools.
* The Cube of Meat gained through this item will persist in the escape sequence of Mines II.
* This item cannot normally be used on Soul Hearts, Black Hearts, Bone Hearts, or Eternal Hearts.
	+ Thus, this item does not work with  The Lost,  ???,  Tainted ???,  Tainted Judas,  Tainted Bethany, or  Tainted Lost. Using it will not hurt them, nor produce any Cubes of Meat.
	+ Bone Hearts do not qualify either, so  The Forgotten and  Tainted Forgotten cannot use this item.
* If Isaac has Ball of Bandages, Cubes of Meat will be added regardless.
	+ Harbingers will preferentially drop Cubes of Meat if Isaac has both types of orbitals.
* In Repentance Co-Op the Cube of Meat gained through this item will persist when a player dies allowing them to have a powerful damage output while in ghost form.

## Synergies

* +  as  Judas /  Dark Judas: Each use grants a permanent +0.5 normal damage up in addition to a +0.2 flat damage up.
* : Spawns an indestructible wisp. The wisps do not orbit Isaac, block shots, or deal contact damage. Instead, they chase and constantly shoot at nearby enemies.
* : Every Cube of Meat produced using Potato Peeler counts as an item for rerolling. Because health usually is not removed when rerolling items, this is useful to increase the number of items at the expense of the item pool.
	+ Cubes of Meat created by Potato Peeler will always reroll into Treasure Room items, regardless of where Potato Peeler was obtained or the rooms it was used in.
* /: The temporary hearts granted by the cards can be used to create a Cube of Meat.
* Tainted Eden: The  is not re-rolled when Tainted Eden takes damage, but the loss of a heart container is also permanent.

## Interactions

* : The Cubes of Meat from Potato Peeler cannot be duplicated by Box of Friends.
* : No effect.
	+ Car Battery + : Summons 2 wisps and one Cube of Meat upon use.

## Trivia

* In earlier versions of Repentance this item used to kill any characters with red hearts when used while they are  The Lost.
* The description on this item matches the name of the item .
* The pickup quote "A pound of flesh" is a reference to Shakespeare's *The Merchant of Venice*.
* This item might be a reference of the infamous suicide of Petunia from Happy Tree Friends' episode Wishy Washy (content warning: extreme cartoon gore).

Ouija Board

**Ouija Board** is a passive item.

## Effect

* Grants spectral tears that travel through obstacles (but not enemies) instead of breaking on impact with them.
* +0.5 tears.

## Synergies

* : When tears pass through solid objects, they will split, resulting in many tears shooting out from every rock the original tear passed through.

## Interactions

* Azazel// Tainted Azazel: The beam becomes translucent, but spectral has no effect.
* : Bombs will become translucent and pass through objects.
* : Spectral has no effect.
* The Forgotten: Spectral provides no benefit for both characters, as the bone club can hit through obstacles and  The Soul has spectral tears passively.

* : The knife becomes translucent, but spectral has no effect.

* Heals 1 additional Red Heart when picked up.

## Notes

* This item can rarely drop from polyps.
* The regeneration can happen multiple times in the same room, so there is no need to move between rooms to continue regeneration.
	+ However, regeneration **does not occur** when standing in a Crawl Space.
* Regeneration will only occur when Isaac has Red Heart containers or **something equivalent**:
	+ Keeper's and  Tainted Keeper's coin hearts will regenerate, one coin at a time.
	+ Bone Hearts regenerate like red hearts.
	+ Consequently, characters with no applicable health --  ???,  The Lost,  Dark Judas,  Tainted Bethany,  Tainted Judas, and  Tainted Lost—do not benefit from the effect.
