Keeper Donate 1000 coins to the Greed Donation Machine
Added in Afterbirth
Disambig.png 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 coins to the Greed machine. Keeper starts with 1 bomb and a triple shot similar to The Inner Eye The Inner Eye.

  • Keeper starts with Wooden Nickel Wooden Nickel after defeating Isaac with Keeper.
  • Keeper will start with 1 coin pickup after defeating Hush with Keeper.
  • Keeper will start with Store Key Store Key after defeating Satan with Keeper.

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 coin every time he picks up a coin. All types of hearts are transformed into blue flies. If Keeper falls to one Coin Heart container (Devil deal, Health Down,..), any HP Up will increase his health back to two Coin Hearts.

Unlockable items[edit | edit source]

Notes[edit | edit source]

  • Keeper cannot have more than 2 Coin Hearts.
    • The only exception to this is Added in Afterbirth †Greed's Gullet Greed's Gullet, which allows him to have up to 6 Coin Hearts.
  • Keeper always takes one full Coin Heart of damage, which means he generally cannot have half Coin Hearts.
  • 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 A Quarter A Quarter will give 1, 4, 9, and 24 coins respectively if used to heal.
    • Using a Lucky Penny to refill health will not give a coin, but will still give +1 Luck.
    • 2 of Diamonds 2 of Diamonds can refill Keeper's health at the cost of 1 coin.
    • Counterfeit Penny Counterfeit 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 Devil/Angel Room chance, Devil deals, Challenge Rooms, Boss Challenge Rooms, and items such as Added in Afterbirth †Dark Prince's Crown Dark Prince's Crown.
    • Because Keeper can usually not have less than one full heart, items such as Whore of Babylon Whore of Babylon and Empty Vessel Empty Vessel cannot be activated.
    • Taking a Devil deal costing 2 Red Hearts will kill Keeper.
  • If Keeper only has one Coin Heart, using XI - Strength XI - Strength will give Keeper an additional Coin Heart that does not disappear upon leaving the room.
  • IV Bag IV Bag only gives Keeper 0-1 coins per use (instead of 1-3).
  • Piggy Bank Piggy Bank only allows Keeper to drop 0-1 pennies when taking damage (instead of 1-2).
  • Despite having an innate triple shot, Keeper does not start with The Inner Eye The Inner Eye. Because of this, the item can still spawn, and picking it up causes Keeper to fire six shots at once at a slower firing rate.

Strategy[edit | edit source]

  • Due to his 2 Coin Heart limit, Keeper can easily die due to fast shooting enemies, and 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.
    • Removed in 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 makes Keeper able to heal himself in the case where he would take a hit from an enemy.
  • Try to bomb as many urns as possible during Chapter 1; Swallowed Penny Swallowed 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. Ultra Greed attacks make the player lose coins when damaged, which means that Keeper can heal himself as long as he possesses coins.
  • It is possible to take a 2 Red Heart Devil Deal by using Judas' Tongue Judas' Tongue, a Health Up Pill or XI - Strength XI - 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 would be one hit away from death. However, if the boss item is a normally-useless HP up (Stem Cells Stem Cells, A Snack A 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.
  • As Keeper starts with triple shot, his tear rate is quite low, and this can be troublesome against fast enemies or too many enemies. 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.
  • Curse 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 Wooden Nickel Wooden Nickel unlocked, it's not guaranteed that you will leave the Curse Room alive. Also, pills should be used outside of the Curse Room because using an "Addicted!" pill will kill you when you try to leave the room.
    • However, it is possible to enter the Curse Room and remain on 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 invincibility is still active.
  • Pills can be risky to use as the Keeper since many have adverse effects and these adverse effects can quickly ruin a run should they happen. Picking up PHD PHD is recommended before trying any pills.
    • The Hematemasis pill will reduce your health, but in exchange, spawn many flies.
  • Hold onto your Joker Joker 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.
    • Keeper's health coins count as Red Hearts for a devil/angel door appearing at all, making Joker Cards, Goat Head Goat Head, or Added in Afterbirth †Eucharist Eucharist invaluable in getting into devil/angel rooms.
  • Co-op babies can be used to exploit blood donation machines and Devil beggars 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 Hush and Mega Satan bring X - Wheel of Fortune X - 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 for healing in mid-battle.

Wooden Nickel[edit | edit source]

After beating Cathedral with Keeper, he will start with Wooden Nickel Wooden Nickel, giving Keeper a source of potential free coin.

  • 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.
  • The Battery The Battery, 9 Volt 9 Volt, Charged Baby Charged Baby, and Car Battery Car Battery help to further increase the amount of coins produced. Having Habit Habit will recharge the Wooden Nickel whenever Keeper is hit, allowing him to potentially sustain himself endlessly, as long as the Wooden Nickel pays out.
  • Sacrifice rooms can be used much more with the Wooden Nickel, as the coins gained from it can be spent on them.

Shops[edit | edit source]

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

The following shop items are particularly useful for Keeper:

Good Items[edit | edit source]

  • 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.
  • Since every heart is changed into flies, items that give extra Heart drops like Gimpy Gimpy, The Virus The Virus, Old Bandage Old Bandage, Fanny Pack Fanny Pack, Bloody Penny Bloody Penny, Serpent's Kiss Serpent's Kiss, Little C.H.A.D. Little C.H.A.D. or The Relic The Relic become great sources to generate flies. Having Hive Mind Hive Mind also helps Keeper deal extra damage to enemies.
  • 1up! 1up!/Dead Cat Dead Cat will allow 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.
  • 20/20 20/20 causes Keeper to shoot 5 tears in an arc, without decreasing his fire rate.
  • Blind Rage Blind Rage has good synergy 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.
  • Cursed Eye Cursed Eye allows him to fire 12 tears without an increase in tear delay.
  • Added in Afterbirth †Dim Bulb Dim Bulb is very useful if you keep the Wooden Nickel, as using it at the start of any room or beforehand will grant a hefty boost to most stats.
  • Diplopia Diplopia/Credit Card Credit Card can be used to take Devil Deal items without spending any hearts.
  • Glass Cannon Glass Cannon works good in early game for killing bosses and large groups of fast enemies, especially when holding Added in Afterbirth †Dark Prince's Crown Dark Prince's Crown or Dead Cat Dead Cat. It's also useful for speeding up the run when the player's goal is Boss Rush or Blue Womb.
  • Added in Afterbirth †Greed's Gullet Greed's Gullet allows Keeper's health to extend past 2 coins, which is normally impossible. 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.
  • Head of the Keeper Head of the Keeper is very useful since enemies will drop coins when hit, which will help Keeper stay alive.
  • Holy Mantle Holy Mantle allows Keeper to enter and leave Curse Rooms with less risk.
  • The Inner Eye The Inner Eye/Mutant Spider Mutant Spider cause Keeper's fire rate to drop considerably, but he shoots 6/7 tears in an arc, allowing for greater damage output.
  • Lucky Rock Lucky Rock can allow Keeper to get coins from rocks as long as he has bombs.
  • Missing Page 2 Missing Page 2 will activate every time Keeper takes damage, making it an effective replacement to The Negative The Negative's The Necronomicon The Necronomicon effect.
  • Added in Afterbirth †Moving Box Moving Box can be used to drop multiple coins in a potentially harder room or boss fight.
  • Piggy Bank Piggy Bank works differently with Keeper and doesn't drop coins every time he takes damage.
  • Placenta Placenta 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.
  • Portable Slot Portable Slot can be used to generate coins to heal Keeper during extended fights and in some cases might be better than Wooden Nickel Wooden Nickel when money is not a concern.
  • Pyromaniac Pyromaniac is great with Keeper too, because now you can also heal yourself with all explosions. Combine this with a good bomb item like Kamikaze! Kamikaze!, Dr. Fetus Dr. Fetus, Epic Fetus Epic Fetus, Ipecac Ipecac and you'll be almost immortal.
  • Both Leech Leech and Yum Heart Yum Heart will heal Keeper.
  • Swallowed Penny Swallowed 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. However, invincibility after taking damage does not last long enough to pick up the money without risk of death.
    • Added in Afterbirth † 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 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 Blood Donation Machines, Devil Beggars and Sacrifice Rooms practically for free until they pay out since each time you donate a coin to them, you get a coin back.
  • Tech X Tech X synergizes well with Keeper's triple shot.
  • Tractor Beam Tractor 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.

Bad Items[edit | edit source]

  • Health Ups are useless when Keeper has 2 health coins. However, if a Devil Room opens while the Boss Room item is a Health Up, the player can pay for a 1 Red Heart Devil Deal and then get the Health Up to get back to full health. XI - Strength XI - Strength can also be used to get back to two health coins, as the health bonus from the card is permanent for Keeper.
  • Devil Deals requiring 2 Red Hearts cannot be taken unless Keeper has a resurrection item, Added in Afterbirth †Coupon Coupon, Credit Card Credit Card, Diplopia Diplopia, Strength Card, a Health Up Pill or Judas' Tongue Judas' Tongue.
  • It is not recommended to take Bum Friend Bum Friend or Bumbo Bumbo as they will pick up coins off the ground that could have been used as health.
  • Taking Abaddon Abaddon 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.
  • Empty Vessel Empty Vessel does not work with Keeper as health coins count as red heart containers.
  • Guppy's Paw Guppy's Paw will remove a health coin and spawn 9 blue flies. Removing all health coins with Guppy's Paw will not kill the Keeper immediately, but he will die upon picking up an item.
  • Maggy's Bow Maggy's Bow, The Jar The Jar, Dark Bum Dark Bum and Immaculate Conception Immaculate Conception will not provide Keeper any benefit, as all heart pickups turn into flies.
  • Maggy's Faith Maggy's Faith does nothing for Keeper and will not grant 5 blue flies when traveling to the next floor.
  • Monstro's Lung Monstro's Lung will take a dangerously long time to charge.
  • The Polaroid The Polaroid, The Negative The Negative or Whore of Babylon Whore of Babylon cannot be triggered by the Keeper since he can't have half a heart of health. An exception is after being revived by Guppy's Collar Guppy's Collar, which is presumably a bug.

Trivia[edit | edit source]

  • 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.
  • 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 since 2016, as Keeper's sprite is changed to this sprite for the day.
  • Keeper having two coins instead of hearts for health is possibly a reference to Charon's Obol, a tradition in northern Mediterranean cultures, particularly Greek and Roman cultures, where one would place a pair of coins on the deceased's eyes to pay Charon, the ferryman of the river Styx, for the trip across, but also to pay for a return trip from the world of the dead if one was expected. This is further supported by the fact The Lost, whose starting coin is also suspected to be a reference to Charon's Obol, only has one coin and is depicted as a spirit, while Keeper has two and is depicted as a corpse, supposing he paid to bring his body back across the river Styx.
  • Keeper's starting health is listed as "2" on the character selection screen, despite having no red hearts. This is unique among such characters, whose health is usually listed as "-1" or "?".
  • The Keeper was created for the sake of being "another challenge character" for this game (the other character is The Lost).
