Apple!

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

## Effects

* Adds a chance to fire razor blades that deal quadruple Isaac's tear damage.
* +0.3 tears.

## Notes

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

1

15
−

⌊

L
u
c
k

⌋

{\displaystyle \frac1 { 15 - \left \lfloor \mathit{Luck} \right \rfloor}}

	+ At base luck (0), the chance is 6.66%, maxing out at 100% at 14 luck.

## Synergies

* /  / : When razors are fired, the split tears will also be razors and do quadruple damage. The Parasite's split tears look like normal tears.
* : Adds a chance for the bombs to deal increased damage. See the page for the specific damage formula.
* : Adds a chance to fire a giant razor that does roughly triple damage.
	+ Adds a chance to fire a giant razor that does quadruple damage (x40 + 10 flat damage).
* : Adds a chance for tears to do quadruple damage. Burst tears will also do quadruple damage if the main tear does quadruple damage.
* : When razors are fired, they will connect to other tears via electricity. The electricity also does quadruple damage.
* : Tears can be fed to razors, increasing damage and splitting into 8 razors after a little while. If razors are fed to the tears, the razor damage doesn't apply to the tear both before and after splitting.

## Interactions

* : Each entire beam has a chance to gain the damage boost.
	+ Each tick of the beam has a chance to gain the damage boost.
* : Overrides Apple!.
	+ Each tick of the laser rings have a chance to gain the damage boost.
* : With 14 luck, overrides Tough Love, as the razor blades do more damage anyways. With 13 luck, Apple and Tough Love each have about an equal chance to trigger.

## Trivia

* Both the item itself and the description is a reflection of one of Isaac's nightmares between floors that involves him finding a razor blade inside a piece of candy.
* The item and pickup quote are a reference to the urban legend of giving away candies with razor blades hidden inside of them as a way of harming people.
Blaster

### Found In

The **Blaster** is an enemy that is exclusive to Mines. It is characterized by a large boulder with holes on its upper body and its lack of arms.

It slowly wanders around and occasionally shoots a Fly Bomb at Isaac. When it shoots, the boulder on its head forms an opening for the Fly Bomb to be shot out of.

Blasters take only 25% damage from non-explosive sources. Their own Fly Bombs can be used against them to quickly defeat them.

## Trivia

* The Blaster first appeared in the *Antibirth* mod.

## Gallery

* A Blaster's appearance in Ashpit.
* Concept art for the Blaster.
Adoption Papers

**Adoption Papers** is an unlockable trinket added in *The Binding of Isaac: Repentance*.

## Effects

* Shops and Black Markets now sell familiars instead of the usual item selection.
	+ The familiars are chosen from the Baby Shop item pool.
	+ While holding the Adoption Papers, the familiars are discounted to 10 coins. If the papers are dropped, they cost 15 coins.

## Notes

* A shop that has already been entered will not have its item selection changed, nor will dropping the papers revert them to normal.
* In Greed Mode, only the shop pool item is replaced with a familiar and discounted.
	+ This also applies to all shop pool items when playing as  Tainted Keeper. Familiars spawned from the Treasure Room pool remain unaffected.
* Familiars that appear in both the Shop pool and Baby Shop pool (, , etc) will be discounted by Adoption Papers even if the shop was visited before the trinket was held.
* After Baby Shop item pool is exhausted, items from normal shop pool will be generated again in shops.
	+ Items generated by this will still discount to 10 coins.

## Synergies

* : Both of the discounts stack, selling familiars for 5 cents.

## Interactions

* : Chaos takes priority in item selection. However, items will still be discounted.
* / : Ignores the effect of Adoption Papers, spawning items from the Shop pool if used there.
* : While one of the items will come from the Baby Shop pool, the other 4 items cycled between will come from the regular Shop pool, all of which still discounted at 10 coins.
* : Does not affect Keeper's Box' items, meaning both familiars and shop items can be purchased in tandem over the course of a run.
* / : The extra shops are unaffected by Adoption Papers.

This article is about the Afterbirth † Bestiary. For the Repentance Bestiary, see Bestiary Repentance.

The **bestiary** is a new addition to *The Binding of Isaac: Afterbirth †* that is accessible through the "Stats" menu. The Bestiary shows information and statistics on all encountered monsters and bosses except for some alternate forms of some enemies.

It shows the number of times an enemy has been encountered, how much health it has, how much damage it has done to Isaac, how many times it's been killed, and how many times it has killed Isaac.

## Notes

* The order of the monsters starts with Rebirth enemies, then Afterbirth enemies, then Afterbirth+ enemies.
* Encountering a boss while fighting Delirium does not count towards the bestiary.
* Seeded and challenge runs will affect bestiary entries, including whether an enemy has been found at least once or not, meaning that regardless of whether achievements are disabled or not, bestiary entries will still be updated.
	+ This also means that enemies spawned using the developer console will be counted as well.
* While fighting Hush, the Blue Boil will count as an encounter but the Blue Gaper will not. A Blue Gaper must be found on its own to be marked as an encounter.

## Pages

*(Click on the images to open the corresponding monster page.)*

## Unlockable Achievements

* : Safely provides the damage boost without needing to take damage.

## Interactions

* : No effect, damage up still caps at +6 and increases at the same intervals
* : Bloody Lust's "rage" effect is shared with Bloody Gust, so if Isaac picks up Bloody Gust after already getting hit with Bloody Lust (or vice versa) the boosts will automatically update to that level.

## Trivia

* In the original *Binding of Isaac*, Bloody Lust only lasted for one room and the damage increase was triggered by killing enemies.
	+ now has the effect of the original Bloody Lust.
* On the character select screen, Samson's starting item is spelled as "Blood Lust".
* Even if Bloody Lust is removed, Isaac will keep the same level of "rage" for the rest of the level. This means that his boosts will automatically update to that level if he picks up another Bloody Lust or a  on the same level.

## Trivia

* Akeldama originates from the *Antibirth* mod.
* Akeldama means 'field of blood' in Aramaic, and is thought to be the monastery where Judas Iscariot committed suicide after betraying Christ in the Bible.
	+ The name comes from a passage from the Gospel of Matthew, where after his betrayal, Judas cast his reward of 30 silver pieces into the temple for the priests. The coins were deemed as 'blood money', so instead of adding them to the treasury, a field was bought to bury foreigners (27:7).
	+ An alternative naming origin comes from the Acts of the Apostles, where it is stated that Judas "acquired a field with the reward of his unjust deed, and falling headfirst he burst open in the middle and all his intestines gushed out," (Acts 1:18-19). This telling in particular is likely where the item description comes from.

### Unlock Method

 Defeat Ultra Greed as  Magdalene

**Censer** is an unlockable passive item added in *The Binding of Isaac: Afterbirth*.

## Effects

* Spawns a familiar projecting a circular aura that slows enemies and enemy shots within its radius and for a short period once they exit.

## Notes

* The aura does not affect bosses but slows down their shots.
	+ Bosses that use tight volleys of projectiles are extremely difficult to avoid without additional items to block, remove, or redirect those shots, as the slowing effect will cause their attacks to clump together.
* Familiars that follow behind Isaac have a certain priority in how close their position is to him over other familiars, with Censer having 4th priority.

## Synergies

* /: The slowing aura mitigates the delay between fast enemies that charge Isaac and the status effect, making it much harder for Isaac to take contact damage.
* /: The slowing aura allows these items to deal with the incoming projectiles more reliably.
* : The slowing aura allows incoming enemies and shots to be more reliably deflected.

## Interactions

* : The aura does not slow things from further away despite increased visual size.

## Trivia

* A censer is a container used to burn incense.

Bloodshot Eye

This article is about the item. For the enemy, see Bloodshot Eye (Enemy).
**Bloodshot Eye** is a passive item added in *The Binding of Isaac: Afterbirth †*.

## Effect

* Summons an orbital familiar eye. This eye shoots in the direction it faces at the time and does contact damage.
	+ The eye deals 2 contact damage per tick or 30 contact damage per second ( 20 damage per second) and its tears deal 3.5 damage. Tears are fired once every 2 seconds.
		- The eye's only shoots tears when enemies are within its line of sight, and shoots once every 1/3rd of a second when it can.
	+ Unlike other orbitals, the eye does not block enemy shots.

## Notes

* Caution is advised when placing Bombs with Bloodshot Eye, as the orbital's tears may knock the bomb elsewhere, and Bloodshot Eye will never stop shooting.
* It may not always be a good idea to pick up Bloodshot Eye if Isaac has one or more Pretty Flies as orbitals, as Bloodshot Eye can override Pretty Flies without giving protection from enemy shots.

## Trivia

* Bloodshot Eye was originally an unofficial item which was supposed to showcase the modding capabilities of Afterbirth+ in the PAX 2016 livestream. However, all items included in the demo were later added to the final game.
Azazel's Stump

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

## Effects

* Gives Isaac a chance to visually turn into  Azazel when clearing a room. Isaac keeps his hearts and items, but changes his tears to be a short range , grants a x1.5 damage multiplier and gains the ability to fly.
	+ The effect lasts until clearing and leaving another room.
	+ The effect can be taken to the next floor.
* When playing as Azazel, the effect instead increases the width of his Brimstone, identical to his  effect.

## Notes

* Dropping the trinket after this transformation will not reverse it until a new room is cleared.
* The trinket only changes Isaac's appearance to be as Azazel's but doesn't change the actual character. This means that the trinket cannot be used to unlock achievements for Azazel.
* The effect will not change Isaac's health mechanics. For example,  The Lost will retain his zero health and .

## Synergies

* Golden Trinket: The chance of Isaac turning into Azazel is multiplied.
* : Isaac retains the damage multiplier and base speed increase after the effect ends. Also removes the tear delay multiplier when transformed into Azazel.

## Interactions

* as **Azazel**: Azazel's Stump has no further effect.
* The Forgotten: Grants flight, but still use his regular bone club attack while in skeleton form. The Soul will work as expected, and use the short range Brimstone.
* Tainted Forgotten: The bone pile will visually turn into Azazel, with no gameplay effects.

	+ When an enemy is killed with the black ring, there is a 15% chance for it to drop a Black Heart.

The chance scales with Isaac's luck. The base chance is 25%, with an additional 2.5% chance per point of luck, capping out at 100% at 30 luck.

## Notes

* The ring is similar in appearance to the combination of  and .
* It is identical to the ring created by .
* Especially effective against Envy and Super Envy. It is also effective against Brownie due to all the Brownie Corns it spawns.
	+ Each piece of Envy/Brownie Corn grants a 15% chance for a Black Heart.

## Synergies

* /: Can allow for substantial chains of enemy kills and rapid room clearing.
* Homing tears: The black ring becomes homing, curving around to hit enemies.
* : Enemies hit by the sneeze will gain a curse that increases the damage the black ring deals to 2x and +3 flat damage. Enemies who die to the black ring under the curse will damage and spread the curse to nearby enemies.
* : Massively increases damage and poisons enemies.  Causes the ring to explode upon contact with walls or obstacles. The explosions can damage Isaac.
* : The ring is much larger and deals 1.5x damage.
* : The ring is much larger but deals normal damage.

Astral Projection

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

## Effects

* The first time Isaac takes damage while in an uncleared room, time is stopped for 2 seconds and Isaac becomes a ghost and leaves his body behind, which drops to the floor. While in ghost form, Isaac has flight and spectral tears and the next hit he takes is negated.
	+ Isaac's tears and speed are greatly increased while time is stopped, although this is not shown on the HUD.

## Notes

* : When getting hit with only one heart left, Astral Projection allows for picking up the dropped heart in the brief time of invincibility even when the player has no hearts left. Failing to do so or having no hearts dropped results in guaranteed death however, but with luck this loop can be used to potentially save runs.

## Interactions

* : The shield will activate before Astral Projection.
* The Lost /  Tainted Lost: The Lost will continue to fight after taking damage, however he will instantly die upon taking damage again or once the room is cleared.
