Binding of Isaac: Rebirth Wiki

(in Repentance)

Tainted Eden is a character added in The Binding of Isaac: Repentance. They are the alternate version of Character Eden iconEden. Unlike other Tainted characters, Tainted Eden has no obvious changes to their physical appearance. Tainted Eden is unlocked by reaching HomeHome and using the Collectible Red Key iconRed Key, Cracked KeyCracked Key, or Soul of CainSoul of Cain to access a special room in one of the walls while playing as Eden.

Like Eden, Tainted Eden starts with random stats, health, possibly some pickups, a trinket, an active item, and a passive item.

Every time they take non-self damage, all of their stats, items (passive and active), their trinket and their currently-held card or pill get re-rolled. Items are guaranteed to re-roll into items from the item pool of the last generated room (i.e. If one were to enter every item-containing room without picking up the items, then entered, for example, an Angel Room, every item that was already spawned will reroll into angel deal items when Tainted Eden receives damage).

Strategy[ | ]

  • The re-rolls will easily remove health, but not restore it. This makes it risky to focus solely on Red Hearts or Soul Hearts, and a balanced approach is overall safer.
    • There is no guarantee of consistency to Tainted Eden's health; While acquiring Soul or Black Hearts may be a good idea because they cannot be re-rolled away, there is a chance that Tainted Eden rerolls into a build with massive amounts of red health, causing the overflowing Soul health to irrevocably disappear.
    • It's not a good idea to get full 12 hearts. Having 6-9 hearts and leaving some hearts on ground to take when needed is much safer.
    • Curse Of Unknown is also potentially dangerous if one gets hit a lot, as your health is truly unknown.
    • Since both getting and losing Heart Containers easily happen, it could be a good strategy to turn temporary Heart Containers into other resources whenever possible (by making devil deals or using both Collectible Guppy's Paw iconGuppy's Paw or Collectible Potato Peeler iconPotato Peeler).
  • Gaining Heart Containers from sources other than passive items, such as Health Up pills, Collectible Converter iconConverter or Eternal HeartEternal Hearts is beneficial, because those changes are not affected by Tainted Eden's mechanic.
    • Try to remember how many heart containers are gained by these way before using them in devil deals or so.
  • More than other characters, Tainted Eden benefits from quantity over quality of individual items since the items are likely to get re-rolled several times anyway. Obtaining as many passive items as possible means more items to re-roll and more chances for useful synergies.
  • Getting items from more consistently positive item pools can make a big difference. In particular, Angel Room items and Planetarium items are high-quality on average.
    • Remember to check ShopShop, as which may provide discounted items, and passive items in Shop item pool may be re-rolled into great items like Collectible Blue Map iconBlue Map or Collectible Black Candle iconBlack Candle, whose effects last for the current floor. Collectible Birthright iconBirthright can only be purchased in shops, it can't be obtained via a reroll.
    • Passive Secret Room items can offer powerful synergies, but run the risk of re-rolling into Collectible Missing No. iconMissing No. and Collectible TMTRAINER iconTMTRAINER, both of which are extremely detrimental to almost any run. To avoid ever getting the latter item, consider defeating The Beast last, as that's what unlocks it. However, while Secret RoomSecret Room passive items are very risky, active items are instead very useful to keep around, as they are generally powerful, and they can be re-rolled into Collectible R Key iconR Key or Collectible Death Certificate iconDeath Certificate.
    • Active Devil Room Items are also very useful to keep around, as which can be re-rolled into Collectible Damocles iconDamocles or Collectible Guppy's Paw iconGuppy's Paw.
    • Focusing heavily on Devil Room items and not relying on Red Heart Containers in the first place is a viable strategy if plentiful Soul Hearts are acquired.
  • Carrying around a Trinket, even a useless one, carries the opportunity of re-rolling it into a very good one, such as CancerCancer or Cracked CrownCracked Crown and so on.
  • Cards, Runes, and Pills that aren't useful at the moment but may be useful later should be left or dropped on the ground so as to not lose them if a re-roll occurs. They can always be picked up later.
  • The LibraryLibrary can be powerful for Tainted Eden. If Collectible Book of Virtues iconBook of Virtues is acquired from a Library, it cannot be re-rolled away due to how Book of Virtues is the only passive item in the Library item pool.
  • Holding NO!NO! when taking a hit will re-roll Tainted Eden's active item into a passive item, which may or may not be desired.
  • Plenty of trinkets don't need to be held constantly to benefit from their effects, so dropping them when they aren't needed is often advisable. In particular, trinkets that affect level generation like Bloody CrownBloody Crown, Telescope LensTelescope Lens and Fragmented CardFragmented Card can be dropped in the starting room of each floor, and only returned to once ready to proceed to the next.
  • After rerolling everything, check if rocks are destroyed when walking into them. Several effects grant the ability to walk into rocks to destroy them, such as Collectible Thunder Thighs iconThunder Thighs or Collectible Leo iconLeo.
  • Whenever getsCollectible We Need To Go Deeper! iconWe Need To Go Deeper! or Collectible Red Key iconRed Key, try to get a Crawl SpaceCrawl Space/ Ultra Secret RoomUltra Secret Room as soon as possible before they are re-rolled.

Notes[ | ]

  • Self-damage (Blood Donation MachineBlood Donation Machines, Devil BeggarDevil Beggars, Curse RoomCurse Rooms, etc.) will not trigger a re-roll. Fatal damage will also not trigger a reroll.
  • Tainted Eden cannot reroll Collectible The Negative iconThe Negative, Collectible The Polaroid iconThe Polaroid, Collectible Dad's Note iconDad's Note, Collectible Damocles iconDamocles, Collectible Dogma iconDogma, Collectible Key Piece 1 iconKey Piece 1, Collectible Key Piece 2 iconKey Piece 2, Collectible Knife Piece 1 iconKnife Piece 1 and Collectible Knife Piece 2 iconKnife Piece 2, or glitched items (such as ones created by Collectible TMTRAINER iconTMTRAINER).
    • Note that Collectible Missing No. iconMissing No. can be re-rolled into, but can't be re-rolled out of.
  • Powerful transformations such as GuppyGuppy are difficult to attain, as transformations are removed if the appropriate items are re-rolled.
    • However, picking up active items will also counts as transformation progress, which allows GuppyGuppy and BookwormBookworm much easier to keep.
  • If Gulp! pills or a Collectible Smelter iconSmelter are available, absorbing trinkets makes them permanent. If possible, they should be discarded to avoid losing them to a re-roll while looking for better trinkets.
  • If Tainted Eden re-rolls while holding two trinkets (such as from Collectible Mom's Purse iconMom's Purse or Collectible Belly Button iconBelly Button), the trinket in the second slot is dropped rather than re-rolled. The same case happens with active items and Schoolbag.
  • Each roll is seeded. For instance, reverting a re-roll with Collectible Glowing Hourglass iconGlowing Hourglass then getting hit will always give Tainted Eden their Glowing Hourglass back.
  • Since Cards and Pills are re-rolled on hit, Tainted Eden should pick up 0 - The Fool0 - The Fool before the fight with Boss Mom ingameMom and drop it at the beginning of the battle, so as to not lose it if they take damage, if they intend to use it to open A Strange Door.
  • Multiple copies of an item will be re-rolled into different items.

Items[ | ]

While "good items" and "bad items" are less of a factor of choice than for other characters since they are frequently re-rolled, there are some that should be of special notice if found or re-rolled into.

Good Items[ | ]

  • Collectible Abyss iconAbyss: Can be re-rolled, but the locusts are permanent. Better using it on passive Secret Room items or glitched items.
  • Collectible Birthright iconBirthright: Prevents items acquired before Birthright was picked up from being re-rolled. This includes normal re-rolls from items like Collectible D4 iconD4 and Collectible Missing No. iconMissing No., not only the damage-triggered re-rolls.
    • If Birthright is discovered in a shop it might be worth taking damage a few times to try to reroll a powerful synergy before locking it in with Birthright.
    • Collectible Birthright iconBirthright will prevent the currently held active item from re-rolling. However, if it is replaced, active items (including the original) will continue to be re-rolled.
  • Collectible Black Candle iconBlack Candle / Collectible Treasure Map iconTreasure Map /Collectible The Compass iconThe Compass / Collectible Blue Map iconBlue Map / Collectible The Mind iconThe Mind: Triggers effect for the current floor, which won't be lost by re-rolling.
  • Collectible Converter iconConverter /Collectible Empty Heart iconEmpty Heart: Grants Red Heart Containers which won't be re-rolled away, significantly improving Eden's effective health for the rest of the run.
  • Collectible D8 iconD8: Stats multiplier won't be re-rolled.
  • Collectible Damocles iconDamocles: Greatly increases quantity of items. Active items can be re-rolled into it and its passive effect cannot be re-rolled.
  • Collectible Death Certificate iconDeath Certificate: Allows Tainted Eden to get Collectible Dogma iconDogma, which cannot be re-rolled.
  • Collectible Diplopia iconDiplopia: Gains extra items from certain item pool, which also a tricky way to progress GuppyGuppy transformation by copying Collectible Guppy's Head iconGuppy's Head and/or Collectible Guppy's Paw iconGuppy's Paw.
  • Collectible Esau Jr. iconEsau Jr.: The ability to fly gained when transforming into Esau Jr. won't be re-rolled away, even when losing this active item.
  • Collectible Friendly Ball iconFriendly Ball /Collectible Poke Go iconPoke Go / Collectible Mystery Egg iconMystery Egg / Collectible Friend Finder iconFriend Finder: Summoned friendly monster will persist after the items are re-rolled away.
  • Collectible Flip iconFlip: Provides extra passive items.
  • Collectible Glowing Hourglass iconGlowing Hourglass: If used after getting hurt in the same room, will return Tainted Eden to their previous build upon landing in the previous room. Should Tainted Eden get hurt again without ever dropping their previous active item, they will always re-roll it into Glowing Hourglass.
  • Collectible Heartbreak iconHeartbreak: Only broken hearts inflicted from taking lethal damage will persist if the item is rerolled. Will activate if rerolled into after taking otherwise fatal damage, which can save a run.
  • Collectible Holy Mantle iconHoly Mantle: Triggering Holy Mantle will not trigger rerolls, helping Tainted Eden keep their current build.
    • Collectible Blanket iconBlanket: Serves as a weaker version of this, for boss battles only.
  • Collectible Lost Soul iconLost Soul: Lost Soul respawns whenever it was re-rolled into, which makes it easier to get the reward.
  • Lil ClotLil Clot / Collectible Sumptorium iconSumptorium: Summoned clots will persist after the items are rerolled away, acting as semi-permanent familiars until they die.
  • Collectible Monster Manual iconMonster Manual: Familiars summoned by it will last for the current floor.
  • Collectible Prayer Card iconPrayer Card: If retained long enough to be used a few times, Tainted Eden will be able to gain significant permanent Health, which is hard to come by for them.
  • Panic ButtonPanic Button: Because self-damaging items do not trigger rerolls, a strategy can be to hold such a self-damaging active such as Collectible Razor Blade iconRazor Blade or Collectible IV Bag iconIV Bag in conjunction with this trinket to protect Tainted Eden from rerolls and even slightly benefit from receiving damage.
  • Collectible Purgatory iconPurgatory: The effect will remain for the current room even if the item itself is re-rolled, providing a helpful boon during boss battles.
  • Collectible Quints iconQuints: Any familiar summoned with Quints will remain for the current room even if the item itself is re-rolled, making it useful for long boss battles.
  • Collectible Red Key iconRed Key: Provides chance to get more items by exploring Red RoomRed Room (especially Ultra Secret RoomUltra Secret Room).
  • Collectible Smelter iconSmelter, Collectible Marbles iconMarbles, or Gulp! pill: Swallowed Trinkets will be kept permanently.
  • Collectible Red Stew iconRed Stew: The temporary damage boost is retained even after the item is re-rolled, potentially acting as a semi-permanent item effect until the damage boost is lost completely.
  • Collectible The Swarm iconThe Swarm: The orbital flies granted do not disappear if the item is re-rolled.
  • Collectible We Need To Go Deeper! iconWe Need To Go Deeper!: Opening a Crawl SpaceCrawl Space will provide a great opportunity, either getting an extra item or getting a Black MarketBlack Market.

Bad Items[ | ]

  • Collectible Missing No. iconMissing No.: Doesn't do anything except doing more massive reroll. Generally makes you lose a passive Secret Room Item.
  • Collectible TMTRAINER iconTMTRAINER: All items picked up after an item re-rolls into TMTRAINER will become glitched items. Glitched items will not re-roll anymore and will frequently be detrimental with their completely random effects.

Situational Items[ | ]

  • Collectible Blood Oath iconBlood Oath: Despite both Damage and Speed boosts will lasts for a floor after it was re-rolled, it is pretty hard for Tainted Eden to make good use of it, however.
  • Collectible Brittle Bones iconBrittle Bones: Removes all Red Heart Containers but grants 6 Bone Hearts. Fire rate upgrades applied from every lost bone heart stay even after re-rolling. Can be very strong if taken early or if low on Red Heart Containers. On the other hand, if Tainted Eden has a lot of permanent Red Heart Containers from Eternal Hearts and Health Up pills, it could be detrimental. Re-rolled into it will not have any disadvantage.
  • Collectible Chaos iconChaos: When re-rolled into, any item appearing before Chaos in the item list (that is, older items) will re-roll into items from the correct pool, and items appearing after Chaos (that is, younger items) will be from random item pools.
  • Collectible False PHD iconFalse PHD: Damage bonus will lose after re-rolling it. Try to focus on eating bad pills that drop Black HeartBlack Hearts.
  • Filigree FeatherFiligree Feather: Allows for more angel room items to be added to Eden's passive item pool, at the cost of being unable to go to Mega Satan.
  • Collectible Genesis iconGenesis: Using it will remove all non-rerollable benefits you get, and it also removes itself (which actually makes you lost an active Angel Room item).
  • Collectible Guppy's Paw iconGuppy's Paw: Converts one Red Heart Container into three Soul Hearts. Obtained early enough in a run, it allows for Heart Containers that are granted by passive items to be converted into Soul Hearts that can not be re-rolled.
  • Collectible Magic Skin iconMagic Skin: After using and re-rolling it, it will replace future items into itself, which reduce quantity of passive items in the future.
  • Collectible Potato Peeler iconPotato Peeler: The Collectible Cube of Meat iconCube of Meat granted are permanent and are unaffected by re-rolls, but the loss of the health container will also be permanent.
  • Resurrection items: If Tainted Eden is holding a resurrection item when they take fatal damage, they will be resurrected and their items will not be rerolled.
  • Collectible Satanic Bible iconSatanic Bible: Provides Black Hearts which are a relatively stable form of health for Tainted Eden. However, using it will also replace the floor's boss item with a Devil Room item.
  • Collectible Shard of Glass iconShard of Glass: The bleeding effect lasts after the item is re-rolled, which provides extra firepower in early game. Red HeartRed Heart dropping effect will lost after re-rolled, however.
  • Collectible Void iconVoid: Stat-ups from absorbed items are removed.

Trivia[ | ]

  • The achievement for unlocking Tainted Eden is "The Capricious", a possible name for the character.
    • "Capricious" means "given to sudden and unaccountable changes of mood or behavior," fitting Tainted Eden's concept of complete randomness.
  • Tainted Eden's hairstyle will change every time they are hit.
  • On the stage transition screen, their body glitches in a unique animation. Prior to Version 1.7.5, their portrait did not appear whatsoever.
  • Tainted Eden's starting stats are listed as "?" on the character selection screen.
  • In-development, Tainted Eden's effect was a full reroll upon acquiring a new item that excluded the item triggering the reroll rather than having the reroll be triggered by damage. This was changed because in testing players would simply stop picking up items once they found something good enough to be worth keeping.[1][2]
  • Oddly enough, Tainted Eden unlocks XXI - The World?XXI - The World?, associated with stagnation and inertia, this in relation of unfinished goals, lack of motivation and roadblocks, as any builds Tainted Eden makes will be lost in a hit, causing runs to feel meaningless and take free hits hoping for a better build or require absolute perfection to keep a strong build.

Bugs[ | ]

Bug Bug! If Tainted Eden is firing Collectible Technology 2 iconTechnology 2 when damage triggers a re-roll, sometimes the laser persists firing in the last-fired direction until leaving the room, even picking up new synergies as other items reroll.
Bug Bug! If the active item is re-rolled into Collectible Alabaster Box iconAlabaster Box it will be fully charged instead of discharged as usual.
Bug Bug! If Tainted Eden first looks at an item on a floor (such as treasure room items, shop items, golden chest item drops, etc), but does not take them until after walking into a new room with an item in it (such as a Devil/Angel room), those items will be re-rolled into items of the pool most recently walked into.
Bug Bug! If Tainted Eden rerolls into modded items that must be unlocked to be acquired, and they are not unlocked, the item will be rerolled into nothing, and you will lose an item. This can also cause crashes.
