Greed

This article is about the boss. For the game mode, see Greed Mode.

Degraded Mini-Boss

**Greed** is a mini-boss and one of the Seven Deadly Sins. He can appear in Shops starting on the second floor of Chapter 2 or Secret Rooms starting on the first floor of Chapter 3.

* He also has a small chance to spawn when destroying a special shopkeeper.

## Behavior

Greed wanders randomly around the room and performs one of two attacks:

* Fires a spread of 3 projectiles in the cardinal direction closest to Isaac.
* Spawns 2 Hoppers to his either side.

If hit by Greed, Isaac loses 2-4 coins and drops 1-3 Pennies on the floor.

Greed deals a whole heart of contact damage.

## Unlockable Achievements

* The Book of Sin - Defeat all 7 Deadly Sins.

## Notes

* Shops and Secret Rooms Greed is encountered in count as Mini-Boss Rooms, and cannot be bombed out of. They also prevent any other Mini-Boss Rooms from generating that floor.
* Once Greed is encountered in a Shop or Secret Room, Super Greed replaces him in subsequent Shops and Secret Rooms. After Super Greed is encountered in the same manner, they cannot spawn in Shops or Secret Rooms for the rest of the run.
* If Isaac teleports out of the room after defeating Greed but without killing all of the Hoppers he spawns, Isaac can re-fight Greed for extra coins or copies of Steam Sale.
* Greed spawned by blowing up a special shopkeeper can never spawn as Super Greed, even if another Greed was encountered before.

## Trivia

* Greed has his own account on Twitter. This was uncovered after the community dug up a figurine of Greed covered in Sharpie marks during an ARG, which quickly led to his account. After guessing his password, and tweeting on it, the password was quickly changed and was then used to announce the arrival of  Keeper.
* The Seven Deadly Sins that these mini-bosses are based upon are, in Christian teachings, a classification of vices from which all others are derived.
* Greed is a personification of one of the Seven Deadly Sins, with Greed being described as an inordinate desire to possess something, whether that be wealth, power, etc. Greed is a desire to possess something even if it means doing something immoral. Greed can lead to sins such as deception, violence, hardheartedness, and ingratitude.

	+ The creep deals damage much more rapidly at 20 damage per second.
* 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 Headless Baby having the lowest priority at 6th and thus being farther from Isaac than familiars of different priorities.

## Interactions

* : Familiar is bigger; however, no effect on creep damage.
Hard mode

**Hard mode** changes the gameplay compared to Normal in some ways to make it more difficult.
When playing in Hard mode, a small red pentagram () appears on the HUD, below the pickups.

## Differences

* 2-3 more rooms generate each floor.
* Standard rooms with a difficulty of "1" cannot generate.
	+ Standard rooms with a difficulty of "1" have a reduced chance of appearing.
	+ Most rooms with this difficulty are very easy, making difficult rooms more common.
* Rooms with a difficulty of "15" are able to generate on the second floor of chapters 1-4.
	+ Additionally, they can always spawn on single floor chapters.
* Enemies have a base 20% chance to become Champions instead of only 5%.
* Champion enemies only award pickups 33% of the time instead of 100%.
* Hearts are 66% less likely to drop after completing a room.

* Only champion bosses will drop hearts; normal bosses will not.
* Floors are more likely to have curses.
* Slot Machines are half as likely to pay out.
* Blood Donation Machines only give out one coin per use.

* The drop rate of soul hearts from blue fires is decreased to 10%, instead of 25%.
* Tinted rocks have a lower chance of appearing.
* Certain enemies and bosses have increased shot and movement speed.
* does not provide the effect of.

## Trivia

* Before update 1.03, the reduced drop-rate affected all pickups (not just Red Hearts).
* Most Hard mode unlocks are co-op babies, with the notable exceptions of , , , ,  and the character   Bethany.
* 's unlock requirements were extended in later DLCs due to the addition of more completion marks, but it can still be unlocked in the base game using the same method.

* None of the tainted characters have unlocks tied to getting all completion marks, apart from .
Holy Grail

**Holy Grail** is a passive item.

## Effects

	+ The familiar can pass through obstacles.
	+ The familiar can retrieve pickups like .
	+ Blocks enemy tears when stationary and when thrown.
	+ After returning to Isaac, it has a short recharge time before it can be fired again.

## Notes

* Just like , Jaw Bone can grab pickups through obstacles and will **not** grab Troll Bombs.
* Familiars that follow behind Isaac have a certain priority in how close their position is to him over other familiars, with Jaw Bone having the lowest priority at 6th and thus being farther from Isaac than familiars of different priorities.

## Synergies

* : Familiar grows in size and does a flat 14 damage to enemies.
* : Jaw Bone will face in the same direction as Isaac and remain stationary as opposed to trailing behind him. Jaw Bone can still be fired.
* : After being thrown, Jaw Bone will return to Isaac and then reappear behind King Baby.

## Trivia

* This item is possibly a reference to Judges 15:16 where Samson kills a thousand men with a donkey's jaw bone.
* Jaw Bone is possibly a reference to the movie, The Frighteners, where Judge chases a ghost hound who keeps stealing his jaw bone.

## Gallery

* Concept for Jaw Bone (labeled as "Jaw") on the right side, along with other Booster Pack items and trinkets, by Edmund McMillen.
Hanger

### Found In

**Hangers** are dead Shopkeepers that are hostile. They can shoot 3 projectiles at the player that will steal coins on hit (similar to Greed and Keepers).

	+ Petrification lasts for 4 seconds after entering the room.
	+ The chance for enemies to be petrified increases with luck, reaching 100% at 40 Luck.

## Notes

* The freezing effect is the same granted by  tears.
* Bosses cannot get frozen, but have the same chance to be petrified when entering a room.
* Every room has a predetermined set of enemies that are going to be petrified. Re-entering the room will not change this, similarly to Champion enemies.

## Synergies

* : Extends the time period that allows for enemies to be frozen after the petrification effect ends from 2 to 6 seconds.

## Trivia

* The reason Ice Cube is unlocked by completing Pica Run is probably due to pagophagia (the desire to eat ice), a common example of pica.
Harbingers (Bosses)

## Effects

* Grants a permanent 50% chance to resurrect on death.
	+ Resurrection leaves Isaac at half of a Red Heart, or half a Soul Heart if he had no Red Heart Containers.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into Guppy.

## Notes

* Resurrection items activate in a set order. Guppy's Collar is  4th /  6th in this order after , , ,  Lazarus' inherent extra life ( swap the order of the previous two), and .
* It is possible to obtain two collars by finding one in a Red Chest, without picking it up, and then finding another collar in a different Red Chest.  However, this does not have any additional effects and does not count towards transforming into Guppy.
	+ Obtaining multiple copies of Guppy's Collar now grants extra lives, depending on how many copies are obtained (obtaining a second collar displays the lives count as '2?', and so on). The chance for Guppy's Collar to activate is defined with separate rolls, but increases the odds for one of the collars to revive Isaac. Additional collars also count towards the Guppy transformation.
* Resurrecting in a Curse Room may trap Isaac if he has no way of recovering health or exiting them without losing health.
* Resurrecting via Guppy's Collar during a Daily Challenge will count as a death, even if the run is eventually completed.

## Trivia

* This item is a tribute to Edmund McMillen's cat Guppy.
* This item may also be a reference to the *Schrödinger's Cat* thought experiment.
* With this item, at any given point, Isaac will on average be resurrected once more (before he is killed). This is not dependent on how many times he has been resurrected already, a property known as memorylessness.

Horf

**Horfs** are disembodied human heads with their eyes gouged out. Horfs remain immobile in one spot, firing blood shots at Isaac when he gets in their range. They will fire shots directly at Isaac when they're about 1/2 room width away from them, even though their shots can travel the entire room's length. This makes it possible to outrange the Horfs in almost all encounters with them; even if you're in range, they have a slow rate of fire and their shots are slow-traveling as well, and can be dodged simply by moving slightly to the side.

* Horfs have a small chance to be replaced by Sub Horfs.

Jar of Flies

### Collection Grid

*(page 4, column 9, row 4)**(page 4, column 9, row 4)**(page 4, column 10, row 4)*

**Jar of Flies** is an activated item added in *The Binding of Isaac: Afterbirth*.

## Effects

* Killing an enemy adds a fly to the jar, up to a maximum of 20.
* Upon use, releases Blue Flies equal to the number of flies in the jar.
* This item belongs to the  set. Collecting three items from this set will transform Isaac into a giant humanoid fly.

## Notes

* Kills by blue flies and locusts (including flies from the jar) and certain familiars (including  and the launch attack from   Tainted Lilith's fetus) do not add flies to the jar.

* Friendly enemies such as from the  add flies to the jar, but not those spawned from other enemies.
* Batteries do not affect the number of flies in the jar.
* Enemies must be actually *killed* to add a fly; transformations (such as Gapers turning into Pacers) or knockouts (such as incapacitating a Globin) do not count as kills.
* Destroying a Shopkeeper will count as a kill.
* With items that kill normally unkillable enemies, killing things like Stone Grimaces will add flies to the jar.
* Killing minions in the Hush fight does not add flies to the jar.

## Synergies

* : Using Jar of Flies summons wisps instead of Blue Flies; the wisps do not summon the flies when destroyed. Up to five flies at a time are consumed to summon one wisp, with stacking health and damage. The damage of the wisps decreases as they take damage. Enemies killed by wisps’ tears will not add flies to the jar.
* : Doubles the number of flies that spawn.
* : Flies are bigger and deal double damage.
* : Flies will be gained even while the Jar of Flies is in the inactive slot.

## Interactions

* Ace Cards: Enemies that are turned into pickups do not grant extra flies.
* : No effect.
* /: Enemies that are turned into poop do not grant extra flies.
* : Enemies frozen by Uranus do not grant extra flies, even if shattered. Only enemies killed with bombs will add flies.
* : Flies will not collect when absorbed by Void, making the interaction worthless.

## Trivia

* The item's pickup quote references the tagline of the Pokémon games. The quote said "Gotta catch 'em all?"
* With Booster Pack #2, this item's sprite fills up with more flies depending on how many flies it contains. This is based on this Steam Workshop mod by Stewartisme.

## Effects

* Makes farts (e.g. ) significantly larger.
	+ Also affects enemy farts.

## Synergies

* : All enemies killed while infected produce a much larger gas cloud, making the spread much more effective.
* : Increases the knockback amount and radius of the heart when fully charged and the heart makes farting noises when it shoots.
* : Affects all gas clouds produced, increases them in size drastically.
* : The clouds will be larger, increasing the range drastically. The damage is unaffected.
* : Spore explosions count as farts, and increase in size.

## Trivia

* This trinket originated in *Antibirth*, where it was originally called Giant Bean and had the additional effect of stunning enemies.
Isaac's Last Will

**Isaac's Last Will** is the Game Over screen of the game. It is shown whenever Isaac is definitively dead; that is, he doesn't have any more hearts or extra lives. It follows the following format:

 **IN SOME \_\_\_\_\_\_\_\_** | The blank space is occupied by a short description of the current chapter:
* *basement* for Basement, Cellar and Burning Basement,
* *cave* for Caves, Catacombs and Flooded Caves,
* *dark place* for Depths, Necropolis and Dank Depths,
* *warm place* for Womb, Utero and Scarred Womb,
* *barren place* for ???,
* *cold place* for Sheol, Cathedral, Chest, Dark Room,  The Shop, and Ultra Greed,
* *dying memory...* for The Void,
* *sewer* for Downpour and Dross,
* *mine* for Mines and Ashpit,
* *cursed place* for Mausoleum and Gehenna,
* *dead place* for Corpse,
* *faded memory...* for the ascent,
 **XOXO \_\_\_\_\_\_\_\_** | The blank space is filled by the character's name.

 If the Missing Poster trinket is owned at the moment of death, a different version of the Last Will, featuring a jigsaw puzzle piece, will be shown.

## Notes

* If Isaac dies from the timer while using the seed THEG HOST or in SPEED! (challenge #22), the cause of death will be a timer.
* Dying from self-inflicted damage or suicide items when you haven't taken damage from any other sources will have Isaac's face showing on the page.

## Trivia

* "xoxo" is slang for "Hugs & kisses", commonly used in various written communique.
* If you die as  Lazarus Risen, there are blood dots on top of his name.
* Dying as  Dark Judas displays Lazarus's name with blood dots instead of Judas's. This is a bug that is presumed to be caused by the fact that Dark Judas's code may have been written over Lazarus Risen's, as they share similar attributes in numerous points.
* When dying in close proximity to enemies that make fly buzzing noises, their sound effects are slowed down during the Game Over instead of completely stopped. This results in a deep growling noise being heard while staying in the Game Over screen.
Fruit Cake

### Collection Grid

*(page 4, column 13, row 3)**(page 4, column 13, row 3)**(page 4, column 14, row 3)*

**Fruit Cake** is a passive item added in *The Binding of Isaac: Afterbirth*.

## Effects

Each tear that Isaac fires gains a random effect. The possible effects are:

* (Level 4)
* (Level 3)

The following tear effects when generated by Fruit Cake work differently than that of the base item:

* : Isaac will not lose coins from this effect occurring.
* : There is no associated damage up/poison effect/arcing.
* : There is no associated shot speed up.
* : Only the ability to pierce enemies on overkill damage is applied; there is no associated damage bonus with the tear.
* : There is no associated damage multiplier, effectively decreasing damage dealt.
* : There is no associated range up.

 The unique tear effects available to some wisps made by  can also be used by Fruit Cake. This can include:

* Drop hearts/coins/cards/runes on kill. The tear must deal the final hit; earlier hits do not flag enemies to drop the consumable on death.
* Teleport enemies to a random location in the room. This cannot affect Bosses.
* Transform enemies into Poop (similarly to ).
* Transform enemies into random wisps.

Tear effects used in the pool of Fruit Cake do not need their base items unlocked in order to be used. This means that Fruit Cake can occasionally give previews of synergies that are locked.

## Synergies

* : Each tick of brimstone has a random effect.
* : Bombs pull their effects from bomb modifiers (, , , , , , , , , ) as well as tear effects.
* /: Each tick of the laser has a random effect, allowing it to rapidly afflict enemies with multiple status effects.
	+ This also includes the  effect to destroy rocks and enter secret rooms.
* //: Each tear will have its own tear effect.
* : The tear will cycle through different effects, based on Isaac's tear rate.
	+ If Isaac stays in one room long enough the Ludovico tear will often fill the room with many stationary  tears that last until Isaac leaves the room. This combination can easily clear most rooms.
* : The benefits of fruit cake still occur but are short lived due to the high damage of Mom's knife.

## Gallery

* Afterbirth item and trinket concepts, including Fruit Cake.
Glaucoma

**Glaucoma** is a passive item added in *The Binding of Isaac: Afterbirth †*.

## Effects

* This item bears a strong resemblance to .
Gilded Key

**Gilded Key** is an unlockable trinket added in *The Binding of Isaac: Repentance*.

## Effects

* Replaces all new chests with Golden Chests.
* Causes Golden Chests to either grant an item or multiple random pickups. This modifies the contents of Golden Chests to be able to give one or even multiple cards, runes, and trinkets from a single chest alongside normal pickups when it doesn't reward an item.
	+ This includes one or more Lil' Battery and pill pickups allowing Golden Chests to drop these pickups.
* Gives Isaac one Key when picked up for the first time.

## Gilded Key's Changes To Golden Chest Rewards

 1 Card or Rune | 10% | 0%

Random pickup changes

## Notes

* Old Chests and Mega Chests cannot be overwritten by Golden Chests.
* The contents of Golden Chests can be changed retroactively by picking up/dropping Gilded Key. This can even be observed if Isaac has , allowing him to see what the chest would have if he did(n't) have the key and choose which payout he wants.

**I RULE!** is challenge #26. Isaac starts off with , , , , , and . The goal is to defeat Mega Satan. The Boss Room containing ??? or The Lamb does not appear. Additionally, this is one of the few challenges that starts in Hard Mode.

## Difficulty

With a powerful set of items to start with, this is a rather easy challenge after getting used to Mom's Knife. The most difficult challenge here is defeating Mega Satan.

## Strategy

* Because Mom's Knife overrides many other items, finding powerful synergies may prove challenging.
	+ Angel Rooms/Devil Rooms can yield items that synergize with Mom's Knife (such as , , or ).
	+ Boss Rush and ??? can provide additional chances at good items.
* As a result of beginning the challenge with both Key Pieces, Angel Rooms are much more likely to appear than normal.
* It is somewhat easier to beat this challenge with  (which doesn't appear after the Mom fight in *Afterbirth †*) than it is with , as Isaac is an easier fight than Satan in this challenge. Furthermore, the Chest can provide many chances at useful items that the Dark Room does not.
* The Red Chests in the Dark Room now offer Devil Deals, granting powerful items at the cost of Red Heart Containers.

## Notes

* Despite being forced to take , the Cathedral can still be accessed; however, once Isaac is defeated and the chest is entered, the run will simply end and will not count as a completion of the challenge.
	+ Only the path to Sheol will appear after defeating Mom's Heart / It Lives.
* If the player starts the challenge before  and  have been unlocked (using I AM ERROR, a Sacrifice Room, etc.) then the player will need to repeat said method or use another method to advance to Mega Satan.

**Gimpy** is a passive item.

## Effects

* When Isaac takes damage, there is a chance that a Soul Heart may spawn.
* Monsters have a chance to drop a Half Red Heart after being killed. Chance depends on killed monster's base health.

## Notes

* The chance for Gimpy to spawn a Soul Heart depends on the luck stat, and the formula used to determine the chance is:

min
(

1

10
−

⌊

L
u
c
k

∗
0.4

⌋

,
50
%
)

{\displaystyle \min(\frac1 { 10 - \left \lfloor \mathit{Luck} \* 0.4 \right \rfloor},50\%)}

	+ At base luck (0), the chance is 10%, maxing out at 50% at 20 luck.
* The chance for Gimpy to spawn a Soul Heart depends on the luck stat and is based on this formula:

8
%
(
2
%
∗

L
u
c
k

)

{\displaystyle 8\% + (2\% \* \mathit{Luck})}

	+ This means that the chance starts at 8% at 0 luck, minimizes at 0% at -4 luck, and maximizes at 100% at 46 luck.
* Monsters that have less than 10 HP have a 1% chance to drop a Half Red Heart.
* Monsters that have 10 to 29 HP have a 5% chance to drop a Half Red Heart.
* Monsters that have more than 30 HP have a 10% chance to drop a Half Red Heart.

## Synergies

* : For each half heart damaged by Blood Oath, Gimpy has a chance to drop a soul heart. Synergy further improves with luck.
* : Dark Bum can collect the Half Red Hearts that enemies drop, which when combined with the chance to drop Soul Hearts when damaged, is a good way to generate Soul and Black Hearts as well as other pickups.
