This article is about the playable character. For the monster, see Keeper (Enemy).

Keeper is a secret character added in The Binding of Isaac: Afterbirth.

Keeper is unlocked by donating 1000 Penny.pngCoins to the Greed Donation Machine.pngGreed Donation Machine. Keeper starts with 1 Bomb.pngBomb and a triple shot similar to Collectible The Inner Eye icon.pngThe Inner Eye.

  • Keeper will start with Store KeyStore Key after defeating Boss Satan ingame.pngSatan with Keeper.
  • Keeper will start with 1 coin pickup after defeating Boss Hush ingame.pngHush with Keeper.
  • (in Repentance) Keeper will start with three Coin Hearts instead of two after defeating Boss Hush ingame.pngHush with Keeper.
  • (in Repentance) Instead of using coin heart containers to trade for Devil Deal items, they must be bought using coins. One-heart and two-heart deals cost 15 and 30 cents, respectively.
    • Devil Deals created by Collectible Satanic Bible icon.pngSatanic Bible are also paid in coins.
    • Paying cents for Devil Deals will remove the Angel room appearance chance in the same way when other characters pay with heart containers.

Unlike other characters, Keeper uses coins as health. He starts with two Coin Hearts, loses one every time he is damaged, and heals for one every time he obtains a coin, at the cost of a cent. All types of hearts are transformed into blue flies. If Keeper loses Coin Heart containers (Health Down,(except in Repentance) Devil deals, ..), an HP Up will increase his health back up.

Notes

  • This can be quite a tedious character to unlock, because you need to deposit 1000 Coins to the Greed Donation Machine.pngGreed Donation Machine, which takes multiple good runs and good enough luck for the donation machine to not jam/explode too early.
  • (except in Repentance) Keeper cannot have more than 2 Coin Hearts.
  • (in Repentance) Keeper cannot have more than 3 Coin Hearts. This cap applies even before Hush is defeated.
    • The only three exceptions to this are (in Afterbirth † and Repentance)Collectible Greed's Gullet icon.pngGreed's Gullet, which allows him to have up to (except in Repentance) 6 (in Repentance) 7 Coin Hearts, and (in Repentance)Collectible Birthright icon.pngBirthright and (in Repentance)Mother's KissMother's Kiss, which allow him to have an additional Coin Heart.
      • (in Repentance) Greed's Gullet in combination with Collectible Deep Pockets icon.pngDeep Pockets can allow Keeper to reach 12 coin hearts at 600 coins.
        • It is possible to reach 15 coin hearts at 900 coins. Any coin heart container past the max of 12 will appear as an additional row beneath the standard two rows of coin hearts, similar to Character Magdalene icon.pngMagdalene's (in Repentance)Collectible Birthright icon.pngBirthright.
    • Theoretically, Keeper could gain limitless coin hearts by generating and smelting Mother's Kiss, as each copy would grant a heart container, eventually bypassing the 12 heart container cap.
    • If the effect of (in Repentance)Mother's KissMother's Kiss is doubled via Collectible Mom's Box icon.pngMom's Box or a (in Repentance)Golden Trinket Golden Trinket, Keeper will also receive an extra coin.
  • Keeper always takes one full Coin Heart of damage, which means he cannot have half Coin Hearts.
    • Because Keeper can usually not have less than one full heart, items such as Collectible Whore of Babylon icon.pngWhore of Babylon and Collectible Empty Vessel icon.pngEmpty Vessel cannot be activated.
    • The effect of (in Afterbirth †)Collectible Clicker icon.pngClicker can allow Keeper to have half Coin Hearts.
      • (in Repentance)Collectible Clicker icon.pngClicker will now fill one Coin Heart if Keeper would otherwise have no health.
  • The amount of blue flies created from each heart depends on the type of heart.
  • Every time Keeper uses a coin to heal himself, that coin is consumed and isn't added to his current coin amount.
    • Double Pennies, Nickels, Dimes and items that give money on pickup (such as Collectible A Quarter icon.pngA Quarter, Collectible A Dollar icon.pngA Dollar, Collectible Piggy Bank icon.pngPiggy Bank, etc.) will give their amount minus the healed HP.
    • Using a Lucky Penny to refill health will not give a coin, but will still give +1 Luck.
    • 2 of Diamonds2 of Diamonds can refill Keeper's health at the cost of 1 coin.
    • Counterfeit PennyCounterfeit Penny allows the chance for Keeper to gain the full value of a coin while healing.
  • Coin Hearts are generally treated as Red Hearts, such as in (except in Repentance)Devil RoomDevil Room/Angel RoomAngel Room chance,(except in Repentance) Devil deals, Challenge RoomChallenge Rooms, Boss Challenge RoomBoss Challenge Rooms, and items such as (in Afterbirth † and Repentance)Collectible Dark Prince's Crown icon.pngDark Prince's Crown.
    • (except in Repentance) Taking a Devil deal costing 2 Red Hearts will kill Keeper.
    • (in Repentance) Getting hit will not lower the chance for a Devil/Angel room to appear.
  • (except in Repentance) If Keeper doesn't have maximum Coin Heart containers, using XI - StrengthXI - Strength will give Keeper an additional Coin Heart that does not disappear upon leaving the room.
  • Collectible IV Bag icon.pngIV Bag only gives Keeper 0-1 coins per use (instead of 1-3).
    • Collectible IV Bag icon.pngIV Bag + Collectible PHD icon.pngPHD: IV Bag drops 0-2 coins per use.
  • (in Repentance) Blood Donation Machine.pngBlood Donation Machine aren't guaranteed to pay Keeper out with a coin.
  • Collectible Piggy Bank icon.pngPiggy Bank only allows Keeper to drop 0-1 pennies when taking damage (instead of 1-2).
    • (in Repentance)Having a partner in True Co-Op mode can get around this, as the Co-Op partner will drop pennies normally (as long as they are not Keeper themselves), giving Keeper a reliable source of health (the drawback being that the partner will have normal health mechanics and therefore won't have infinite health this way).
  • (in Repentance) Swallowed PennySwallowed Penny only allows Keeper to drop 0-1 pennies when taking damage (instead of 1).
  • Despite having an innate triple shot, Keeper does not start with Collectible The Inner Eye icon.pngThe Inner Eye. Because of this, the item can still spawn.
    • (except in Repentance)The Inner Eye grants six shots with a reduced fire rate.
    • (in Repentance) The Inner Eye grants four shots with a reduced fire rate.
  • (in Repentance) Health Down pills cannot spawn while playing as Keeper.
  • (in Repentance) When Keeper is being played in Co-op mode:
    • If he dies, his ghost baby will maintain his innate triple shot.
    • He will not convert hearts into flies unless he picks up a soul heart or is granted them directly by an item.
    • Devil Deals will use coins for all players.

Strategy

  • As Keeper starts with triple shot, his tear rate is quite low, and this can be troublesome against fast enemies or large groups. Finding Tears Up items/Pills on the early floors will be useful to clear rooms. Items/trinkets increasing the tears' hitbox are also useful as enemies can be hit by two or three tears more easily.
  • Due to his (except in Repentance)2/(in Repentance)3 Coin Heart limit, Keeper can easily die due to fast shooting enemies, and (except in Repentance)Devil Deals costing 2 Red Hearts will kill him. As all hearts turn into flies, Soul/Black Hearts cannot be found to protect the Keeper's health.
  • It is strongly recommended to defeat Boss Isaac ingame.pngIsaac as soon as possible so that Keeper has the Collectible Wooden Nickel icon.pngWooden Nickel, which will vastly improve his survivability.
    • (in Rebirth and Afterbirth) Keeper can take a 2 heart Devil Deal by spawning in a co-op baby, taking the devil deal, then quickly getting rid of the co-op baby, which will leave Keeper with one Coin Heart.
  • Leaving a few coins on the ground when clearing a floor allows Keeper to heal himself if he takes a hit from an enemy.
  • Try to bomb as many urns as possible during Chapter 1; Swallowed PennySwallowed Penny can drop from urns, which is amazing as Keeper (see Good Items).
  • In Greed Mode, as coins spawn during waves, Keeper can easily heal himself during each wave by leaving some coins on the ground, even if this will decrease the amount of coins he will be able to collect and spend in the Shop. Boss Ultra Greed ingame.pngUltra Greed attacks make the player lose coins when damaged, which means that Keeper can heal himself as long as he possesses coins.
  • (except in Repentance) Curse RoomCurse Rooms are very risky to enter as Keeper. Entering it through the door will leave you at one Health, which means if you don't find any coins there, it will end your run. Even with the Collectible Wooden Nickel icon.pngWooden Nickel unlocked, it's not guaranteed that you will leave the Curse Room alive.
    • (in Repentance) With 3 Coin Hearts, entering a Curse Room and leaving through the door will leave you at one Health, which means if you get hit by an enemy inside the room, it will end your run. The Collectible Wooden Nickel icon.pngWooden Nickel does make it somewhat less risky, however.
    • However, it is possible to enter the Curse Room and remain at full health. This is achieved with a coin in the room right next to the Curse Room's door, most easily achieved with Wooden Nickel. The player can then walk into the Curse Room doorframe to take damage, quickly pick up the coin and heal, then walk through the door into the Curse Room while their invincibility frames are still active.
  • (except in Repentance) It is possible to take a 2 Red Heart Devil Deal by using Judas' TongueJudas' Tongue, a Health Up Pill, or XI - StrengthXI - Strength right after paying for the item. This would leave Keeper at 1 health coin (empty if it was recovered using the pill, but he will not be killed), which is quite risky as he will be one hit away from death. However, if the boss item is a normally-useless HP up (Collectible Stem Cells icon.pngStem Cells, Collectible A Snack icon.pngA Snack, etc.), it can make even a 2-heart Devil Deal effectively free if you possess a Strength Card and take the boss item after leaving the Devil Room.
  • (except in Repentance)Hold onto any JokerJoker cards: you will probably be given an item that increases health at some point in your run; before taking it, use your Joker to see if any one-heart devil deals are available.
    • (except in Repentance)Keeper's health coins count as Red Hearts for a devil/angel door appearing at all, making Joker Cards, Collectible Goat Head icon.pngGoat Head, or (in Afterbirth † and Repentance)Collectible Eucharist icon.pngEucharist invaluable in getting into devil/angel rooms.
  • (except in Repentance) Pills can be risky to use as the Keeper since many have adverse effects, with many of them able to quickly ruin a run should they happen. Picking up Collectible PHD icon.pngPHD is recommended before trying any pills.
    • (except in Repentance) The Hematemesis pill will reduce your health, but in exchange, spawn many flies.
      • (in Repentance) The Hematemesis pill will spawn many coins on the floor, making it very useful for quick health regeneration.
    • (in Repentance) Health Down pills are excluded from the pool while playing as Keeper.
  • Co-op babies can be used to exploit a Blood Donation Machine.pngBlood Donation Machine and a Devil Beggar.pngDevil Beggar because babies still spawn with a whole heart while Keeper always has a full coin; thus, the baby's health can be replenished by spawning/respawning.
  • In fights against Boss Hush ingame.pngHush and Mega Satan Head ingame.pngMega Satan, bring X - Wheel of FortuneX - Wheel of Fortune: they will not attack you until you get closer to the center of the room, allowing you to spawn lots of coins from the Slot Machine.pngSlot Machine for healing in the middle of battle.
  • The Keeper can utilize the Sacrifice RoomSacrifice Room much more reliably and efficiently than other characters. To do this, instead of picking up extra dropped coins, leave them all on the floor. When you find a sacrifice room, you can repeatedly step on the spikes for a reward, then go pick up a penny left on the floor. Repeat this process until you are satisfied with your rewards. This process is easier in Repentance, as the player can start with 3 coin hearts rather than 2.
  • Once unlocked, Rib of GreedRib of Greed is particularly useful for Keeper, since it increases the chances of coins dropping after a room clear in place of hearts. This allows for more opportunities to heal.

Wooden Nickel

After beating Cathedral with Keeper, he will start with Collectible Wooden Nickel icon.pngWooden Nickel, giving Keeper a source of potential free coins and health.

  • It's usually a good idea to use the Wooden Nickel right after entering a room, so that the coin dropped will also work as emergency healing.
  • Collectible The Battery icon.pngThe Battery, (in Afterbirth † and Repentance)Collectible Jumper Cables icon.pngJumper Cables, Collectible 9 Volt icon.png9 Volt, Collectible Charged Baby icon.pngCharged Baby, and Collectible Car Battery icon.pngCar Battery help to further increase the amount of coins produced. Having Collectible Habit icon.pngHabit will recharge the Wooden Nickel whenever Keeper is hit, allowing him to potentially sustain himself endlessly, as long as the Wooden Nickel pays out. Having Collectible Habit icon.pngHabit and Collectible Car Battery icon.pngCar Battery increases chances for infinite coins.
  • Sacrifice rooms can be used much more with the Wooden Nickel, as the coins gained from it can be spent on them.
  • Collectible 9 Volt icon.png9 Volt can be used to farm charges infinitely in the room before the boss room or a trap room, as the doors will not automatically open after the normal amount of time. It is easiest if there are any immobile or passive enemies.

Shops

After beating SheolSheol with Keeper, he will start with Store KeyStore Key, giving Keeper free access to Shops.

The following shop items are particularly useful for Keeper:

  • Collectible Hive Mind icon.pngHive Mind: Enhances the many blue flies Keeper will naturally produce.
  • Collectible BFFS! icon.pngBFFS!: Any orbital familiars are important to protect the Keeper's low health, so increasing their size is always good.
  • Collectible Piggy Bank icon.pngPiggy Bank: Drops 0-1 coins with Keeper instead of 1-2, but still provides increased survivability.
    • (in Repentance) In Co-Op, a player not using Keeper can take the Piggy Bank instead for its full benefit and thus supply Keeper with coins when necessary.
  • Collectible Mom's Box icon.pngMom's Box: Can drop Swallowed PennySwallowed Penny, and makes Swallowed Penny drop two coins instead of one, resulting in infinite money.
    • (in Repentance) While this no longer results in infinite money, having a Swallowed Penny that's twice as effective will drastically increase survivability.
  • Any Battery type items (see above)
  • Collectible Sharp Plug icon.pngSharp Plug takes only one HP on use.

Item Interactions

Good Items

  • Because of Keeper's slow rate of fire, any Tears Up items are a boon to him. His tears stat can be raised higher than the normal Inner Eye cap with enough Tears Up. This is because his low Tears stat is separate from his triple shot effect, allowing him to hit the standard Tears levels while having triple shots.
  • Flight is useful in general, and it also lets Keeper enter Curse Rooms with less risk.
  • (in Repentance)Before Hush is defeated, any health increasing items will grant him a 3rd coin heart, greatly increasing his survivability. Once Hush is defeated this no longer applies, as he will start with a 3rd coin heart from the beginning of the run from then on, although these items can still heal Keeper if he is missing health.
  • Since every heart is changed into flies, items that give extra Heart drops like Collectible Gimpy icon.pngGimpy, (except in Repentance)Collectible The Virus icon.pngThe Virus, Collectible Old Bandage icon.pngOld Bandage, Collectible Fanny Pack icon.pngFanny Pack, Bloody PennyBloody Penny, Collectible Serpent's Kiss icon.pngSerpent's Kiss, Collectible Little C.H.A.D. icon.pngLittle C.H.A.D., or Collectible The Relic icon.pngThe Relic become great sources to generate flies. Having Collectible Hive Mind icon.pngHive Mind also helps Keeper deal extra damage to enemies.
  • (except in Repentance) Collectible 1up! icon.png1up!/Collectible Dead Cat icon.pngDead Cat: Allows Keeper to trade all of his health coins in Devil deals, reviving him with 1 health coin for Dead Cat and 0 health coins and 1/2 soul heart for 1up. Keeper can later regain lost health coins with health up items.
  • Collectible 20 20 icon.png20/20: Causes Keeper to shoot 5 tears in an arc, without decreasing his fire rate.
    • (in Repentance) Collectible 20 20 icon.png20/20 grants a similar effect to Collectible Odd Mushroom (Thin) icon.pngOdd Mushroom, giving Keeper a massive Tears Up in exchange for a Damage Down.
  • Blind RageBlind Rage: Has good synergies with money-dropping items. Since coins need to complete its animation before you can collect it, the extra invincibility frames give you a bigger window of opportunity to pick them up.
  • (in Afterbirth † and Repentance)Collectible Brittle Bones icon.pngBrittle Bones: Picking this item up will give a one-time +0.5 tears up ((in Repentance) +0.4 fire rate) and 24 Blue Flies without removing any health. This bonus is retained even if the item is later lost or rerolled.
  • Collectible Cursed Eye icon.pngCursed Eye: Allows him to fire (except in Repentance) 12 (in Repentance) 15 tears without an increase in tear delay.
  • Collectible Charm of the Vampire icon.pngCharm of the Vampire: Charm of the Vampire works with Coin Hearts, therefore providing a consistent source of healing.
  • (in Afterbirth † and Repentance)Dim BulbDim Bulb: Very useful with the Wooden Nickel, as using it at the start of any room or beforehand will grant a hefty boost to most stats.
  • Collectible Diplopia icon.pngDiplopia/Credit CardCredit Card: Can be used to take Devil Deal items without spending any hearts/ (in Repentance)coins.
  • Collectible Glass Cannon icon.pngGlass Cannon: Since Glass Cannon can never reduce Isaac's health to 0 it works well in early game with Keeper for killing bosses and large groups of fast enemies, especially when holding (in Afterbirth † and Repentance)Collectible Dark Prince's Crown icon.pngDark Prince's Crown or Collectible Dead Cat icon.pngDead Cat. It's also useful for speeding up the run when the player's goal is Boss Rush or Blue Womb.
  • (in Afterbirth † and Repentance)Collectible Greed's Gullet icon.pngGreed's Gullet: Allows Keeper's health to extend past (except in Repentance) 2 (in Repentance) 3 or 4 coins with (in Repentance)Collectible Birthright icon.pngBirthright, which is normally impossible. (except in Repentance) DO NOT pick up Dead Cat if you have all available health points using Greed's Gullet. This will instantly kill you, and when you are brought back by the Dead Cat, you will have only 1 hit point which you can no longer increase.
  • Collectible Head of the Keeper icon.pngHead of the Keeper: Very useful since enemies will drop coins when hit, which will help Keeper stay alive.
    • When combined with Collectible Soy Milk icon.pngSoy Milk, it practically guarantees a steady stream of coin drops. This makes the Keeper effectively immortal as long as he keeps collecting those coins.
  • Collectible Holy Mantle icon.pngHoly Mantle: Allows Keeper to enter and leave Curse Rooms with less risk.
  • Collectible The Inner Eye icon.pngThe Inner Eye/Collectible Mutant Spider icon.pngMutant Spider: Cause Keeper's fire rate to drop considerably, but he shoots 6/7 tears in an arc, allowing for greater damage output.
  • Lucky RockLucky Rock: Can allow Keeper to get coins from rocks as long as he has bombs.
  • Collectible Missing Page 2 icon.pngMissing Page 2: Will activate every time Keeper is at one coin Heart, making it an effective replacement to Collectible The Negative icon.pngThe Negative's Collectible The Necronomicon icon.pngThe Necronomicon effect.
  • (in Afterbirth † and Repentance)Collectible Moving Box icon.pngMoving Box: Can be used to drop multiple coins in a potentially harder room or boss fight.
  • (in Repentance)Collectible Options? icon.pngOptions?: Hearts spawned will immediately change to blue flies, giving you both the fly and the other pickup.
  • Collectible Piggy Bank icon.pngPiggy Bank: Works differently with Keeper and doesn't drop coins every time he takes damage. Still, it allows him to sometimes recover from a hit for free. (in Repentance) The same is true for Swallowed PennySwallowed Penny.
  • Petrified PoopPetrified Poop: Similarly, to Lucky Rock, allows for Keeper to acquire coins (and flies) from poops.
  • Collectible Placenta icon.pngPlacenta: Regeneration effect affects the health coins just like regular red hearts and will allow the Keeper to regenerate 1 health coin every minute. As Keeper does not benefit from items that trigger at half a red heart, this item has no downsides.
  • Collectible Portable Slot icon.pngPortable Slot: Can be used to generate coins to heal Keeper during extended fights and in some cases might be better than Collectible Wooden Nickel icon.pngWooden Nickel when money is not a concern.
  • Collectible Pyromaniac icon.pngPyromaniac: Explosions heal Keeper for a full coin heart. Combined with bomb items such as Collectible Kamikaze! icon.pngKamikaze!, Collectible Dr. Fetus icon.pngDr. Fetus, Collectible Epic Fetus icon.pngEpic Fetus, Collectible Ipecac icon.pngIpecac renders Keeper almost unkillable.
  • Items that restore red hearts directly such as Collectible Leech icon.pngLeech and Collectible Yum Heart icon.pngYum Heart will heal Keeper.
  • (except in Repentance) Swallowed PennySwallowed Penny: Is very powerful as Keeper will always be able to heal himself after taking a hit. This can also grant unlimited money since this will sometimes drop a nickel or a dime. (in Rebirth and Afterbirth) However, invincibility after taking damage does not last long enough to pick up the money without risk of death.
    • (in Afterbirth † and Repentance) The coin dropped on hit can be picked up before Keeper's invincibility frames end, making Swallowed Penny even better for him.
    • If Keeper takes damage from entering a Curse RoomCurse Room, the coin will be dropped on the outside and can't be used to heal before leaving.
      • However, if one quickly enters, exits to collect the coin, and re-enters the room before the invulnerability period ends, the Swallowed Penny allows the Curse Room to be traversed with no net loss in life. Just be wary that there may be enemies in the curse room that would lock the door and prevent the player from leaving and collecting the coin outside the curse room.
    • Obtaining Swallowed Penny means you can play the Blood Donation Machine.pngBlood Donation Machine, Devil Beggar.pngDevil Beggar and Sacrifice RoomSacrifice Room practically for free until they pay out since each time you donate a coin to them, you get a coin back.
      • (in Repentance) You are no longer guaranteed to get a coin back.
  • Collectible Tech X icon.pngTech X: Synergizes well with Keeper's triple shot.
  • Collectible Tractor Beam icon.pngTractor Beam: Will make all 3 of Keeper's tears travel along the beam, hitting a single target all at the same time and effectively increasing damage output.
  • (in Repentance)Collectible IV Bag icon.pngIV Bag + Panic ButtonPanic Button: Panic Button will make it so that when Keeper is about to take damage, IV Bag will activate, giving immunity frames to avoid the initial damage and having a chance to heal Keeper right away.

Bad Items

  • Health Ups are useless when Keeper has maximum health ((except in Repentance)2/(in Repentance)3 health coins). They still heal him if he has unfilled health coins.
    • (in Repentance)This does not apply if Keeper has yet to defeat Hush, as they can grant him a 3rd coin heart until that point.
  • It is not recommended to take Collectible Bum Friend icon.pngBum Friend or Collectible Bumbo icon.pngBumbo, as they will pick up coins off the ground that could have been used as health.
  • (except in Repentance) Taking Collectible Abaddon icon.pngAbaddon will instantly kill Keeper, since it takes away all red health and Keeper cannot make use of the Black Hearts given. Amusingly, it will spawn a lot of flies in the process.
    • (in Repentance) Taking Collectible Abaddon icon.pngAbaddon will not kill Keeper as in previous versions, but it will reduce his health to one Coin Heart.
  • Collectible Guppy's Paw icon.pngGuppy's Paw will remove a health coin and spawn 9 blue flies. (except in Repentance) Removing all health coins with Guppy's Paw will not kill the Keeper immediately, but he will die upon picking up an item.
    • (in Repentance) Removing all health coins will kill the Keeper.
  • Collectible Maggy's Bow icon.pngMaggy's Bow, Collectible The Jar icon.pngThe Jar, Collectible Dark Bum icon.pngDark Bum, Collectible Immaculate Conception icon.pngImmaculate Conception, (in Repentance)Collectible Candy Heart icon.pngCandy Heart, and (in Repentance)Collectible Soul Locket icon.pngSoul Locket will not provide Keeper any benefit, as all heart pickups turn into flies.
  • Maggy's FaithMaggy's Faith does nothing for Keeper and will not grant 5 blue flies when traveling to the next floor, like it would if an Eternal Heart spawned.
  • Collectible Monstro's Lung icon.pngMonstro's Lung will take a dangerously long time to charge, giving it terrible usability.
  • Collectible The Polaroid icon.pngThe Polaroid, Collectible The Negative icon.pngThe Negative ((in Repentance) though the damage up still applies), Collectible Empty Vessel icon.pngEmpty Vessel or Collectible Whore of Babylon icon.pngWhore of Babylon cannot be triggered by the Keeper since he can't have half a heart of health. (except in Repentance) An exception is after being revived by Collectible Guppy's Collar icon.pngGuppy's Collar, which is a bug.
  • Collectible The Wafer icon.pngThe Wafer and Collectible Cancer icon.pngCancer have no effect, as Coin Hearts cannot be Half Red Hearts.
  • (in Repentance)Collectible Alabaster Box icon.pngAlabaster Box can only be charged with items that directly give Soul Hearts to the player, as Soul Hearts spawned on the ground will be converted into blue flies.
  • (in Repentance)Judas' TongueJudas' Tongue is completely useless with Keeper. It won't decrease 30 Cent devil deals to 15 Cents, and does not have any other effect.
  • (in Repentance)Collectible Heartbreak icon.pngHeartbreak will remove one coin heart and replace it by a broken heart upon pickup.

Trivia

  • Keeper was publicly revealed to players through an alternate reality game created by the developers; however, files alluding to Keeper's existence already were found after the initial release of Afterbirth. With the conclusion of the ARG, a patch was released to fully add Keeper to the game as a playable character.
  • (except in Repentance)In the game's files, there is a character called "Old Man Keeper", which was most likely meant to be the 2nd Afterbirth character instead of Keeper. However, he was replaced with this Keeper. This sprite is used for April Fool's Day's daily run since 2016, as Keeper's sprite is changed to this sprite for the day.
  • Keeper's starting health is listed as "II" on the character selection screen, despite having no red hearts. This is unique among such characters, whose health is usually listed as "-I" or "?".
    • (in Repentance) The starting health will become "III" after defeating Boss Hush ingame.pngHush with him.
  • The Keeper was created for the sake of being "another challenge character" for this game (the other character is Character The Lost icon.pngThe Lost).
  • As a secret character, Keeper does not appear on the character select screen until unlocked.
  • Edmund has confirmed that Keeper (and by extension, Shopkeeper.pngShopkeepers) is a mummified version of Isaac from previous runs.[1]
