Unlock Method
Use the Red Key or Cracked Key in Home as Eden

Tainted Eden is a character added in The Binding of Isaac: Repentance. They are the alternate version of Eden. Unlike other Tainted characters, Tainted Eden has no obvious changes to their physical appearance. Tainted Eden is unlocked by reaching Home and using either the Red Key or the Cracked Key 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, an active item and a passive item.

Every time they take damage, all of their stats, items (passive and active), their trinket and their currently-held card or pill get re-rolled.

Items are more likely to reroll into other items from the same item pool. This goes especially for Planetarium items.

Notes

• The rerolls 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: a roll that fills the health bar with red hearts and overwrites soul hearts, followed by one that removes them may be dangerous.
• Avoiding curse room, red chest and devil room items may be worthwhile, as a Dead Cat will remove all red health and grant nothing in exchange -- the extra lives are likely to be lost from the first hit taken.
• Powerful transformations such as Guppy are difficult to attain, as transformations are removed with the items.
• Shops are worth investigating, as they are the only source of Birthright that will lock the current set of items. However, Birthright cannot be rerolled into and gathering shop items for rerolling will not work.
• If Gulp! pills or a Smelter are available, absorbing trinkets makes them permanent. If possible, they should be discarded to avoid losing them to a reroll while looking for better trinkets.
• Each item is always re-rolled into the same item (at least within a given seed). For instance, reverting a re-roll with Glowing Hour Glass then getting hit will always give Isaac his Glowing Hour Glass back.
• Since pills and activable items are re-rolled on hit, a recommended strategy to start the Ascent is to only pick up your teleport out pill when ready to fight the boss, and only when you already are on a good enough set of items to not get hit during the Mom fight, since getting hit will most likely re-roll your teleport into something else.

Item Interactions

• Potato Peeler: Potato Peeler will trigger the damage randomization, but the cube of meat granted is permanent.
• Holy Mantle: Triggering Holy Mantle will not trigger rerolls, helping Eden keep their current items.
• Abyss: Abyss can be rerolled, but the locusts are permanent.
• Glowing Hour Glass : If used after getting hurt in the same room, will return Isaac to its previous set of items upon landing in the previous room. Should Isaac get hurt again while holding his previous active item, he will always reroll it into Glowing Hour Glass. Knowing this, players can practice a room in which they got hurt once until they clear it perfectly, and keep the prior item set as long as they keep using this strategy.

Bug!	Tainted Eden consumes Eden tokens at an unpredictable rate: sometimes only one is removed, sometimes two, and sometimes more. The exact reasons and conditions are unknown.
