Binding of Isaac: Rebirth Wiki

Added in Repentance

Genesis is an unlockable activated item added in The Binding of Isaac: Repentance.


  • On use, the character, including stats and all items but initial items, is reset and teleported to a unique Clean Bedroom Clean Bedroom that acts like an I AM ERROR I AM ERROR room. It has a Bed, two random Chest Chests, two Grab Bag Grab Bags, and a random Trinket. The only way out is through the beam of light.
  • For every item removed using Genesis, there will be a set of three items from the removed item's pool to choose from, each set appearing one after the other.
  • If used on one of the final floors of the game, such as Chest Chest, Dark Room Dark Room, or The Void The Void, the beam of light will be replaced with a Crawl Space Crawl Space that leads Isaac back to the starting room of the floor he used it on. In addition, the aforementioned chests will include items. These items will not disappear along the "choice" pedestals. The Mega Satan Door will remain open if it was opened earlier.
  • If used in ??? ???, the beam will teleport Isaac to Cathedral Cathedral.
  • Does not work during The Beast The Beast's fight, instead merely teleporting Isaac to the middle of the room. No items will be removed.


  • Genesis will remove all currently active curses, meaning Curse of the Blind.png Curse of the Blind will not affect the item pedestals present inside the room.
  • Trinkets absorbed using a Gulp! pill or an item such as Smelter Smelter will simply be removed with no extra pedestals granted for them.
  • If used as Jacob and Esau Jacob and Esau, both character's items are removed to offer choices, but Jacob and Esau cannot take two items at once from the choices. Only Jacob items count toward the count of item offered, Esau's items are lost and offer nothing.
  • Tainted Cain Tainted Cain will be able to pick up the items that appear normally, one of the few times (aside from plot items and Death Certificate Death Certificate) he is able to do so.
  • If used as Tainted Lazarus Tainted Lazarus, both form's items are removed to offer choices, while his initial Flip Flip is granted infinite charges and can be used freely in the special room.
  • Tainted Bethany Tainted Bethany will lose all of her Lemegeton Lemegeton wisps upon use, and also her red heart charges.
  • If used as Eden Eden, a new set of items and stats will be generated. The first random passive item Eden starts with is rerolled immediately with no choice of three.
  • If Isaac uses Genesis while in Downpour Downpour / Mines Mines / Mausoleum Mausoleum or their variants, the trapdoor can send him back to the regular floors unintentionally.
    • Using Genesis after defeating Mom's Heart Mom's Heart on Mausoleum Mausoleum II will teleport Isaac to a room that is empty besides a trapdoor leading to Corpse Corpse I and the three item selections.
  • Since Genesis resets Isaac's health, it is one way to remove Broken Hearts.
  • Crawl Space Crawl Spaces can be generated and entered inside the Genesis room, but upon leaving them, Isaac will be returned to the floor Genesis was used on instead of returning to the room.
  • Item Pools will not be reset, however any lost items can be obtained again if they spawn.
  • Using Genesis will not remove items required for progression (such as Knife Piece 1 Knife Piece 1 or 2, Mom's Shovel Mom's Shovel, The Polaroid The Polaroid, The Negative The Negative, Key Piece 1 Key Piece 1 or 2, etc.).
  • Take caution; choosing an active item while holding another one will not drop the previous item to the ground, but replace it.
  • Using Genesis in Womb Womb II / Utero Utero II will only grant access to Cathedral Cathedral.
  • If the player acquires Damocles Damocles and uses it before all items have been collected, then each subsequent item spawned after using it will each spawn an extra item. Unlike the Genesis choices, the other extra items will not disappear upon collecting one of them, potentially allowing the player to obtain a much higher amount of items than usual.


  • Book of Virtues Book of Virtues: Replaces all of Isaac's wisps with 3 normal wisps, in addition to its other effects.


  • ? Card ? Card: If ? Card is used in place of Genesis, Genesis will be counted as an extra item for the choice set.
  • Azazel Azazel / Tainted Azazel Tainted Azazel: Both have the ability to return to the floor Genesis was used on, due to them starting with a 0 - The Fool 0 - The Fool card.
  • Crooked Penny Crooked Penny: Using it on the choice pedestals has the 50/50 chance of duplicating them as normal, or make them disappear, in which case no new ones will spawn.
  • D7 D7: Using it will spawn three items, all of which can be taken.
  • Damocles Damocles / Missing No. Missing No.: Genesis removes these items as well.
  • Echo Chamber Echo Chamber: The consumable pool is reset when Genesis is used, so if it's re-obtained after using Genesis, the previously stored consumable types won't be activated.
  • Eden's Blessing Eden's Blessing: Using Genesis after collecting the blessing during the run will spawn Isaac in the Genesis room already holding a random item. This consumes Eden's Blessing, and the next run Isaac starts will not begin with a random item.
  • Esau Jr. Esau Jr. / Clicker Clicker: Using Genesis as Esau Jr. or after transforming with Clicker will revert back to the original character.
  • Lazarus' Rags Lazarus' Rags / Ankh Ankh: Using Genesis after Lazarus' Rags or Ankh activates will continue as the new character.
  • Glowing Hour Glass Glowing Hour Glass: Using it works as intended and will give back all previous stats, items, pickups, and health.
  • Magic Skin Magic Skin: Genesis does not remove the downside of Magic Skin; any of the choice pedestals can be replaced by Magic Skin.
  • Pandora's Box Pandora's Box: Using it inside the Genesis room will spawn The Bible The Bible. Picking it up does not affect the choice pedestals.
  • Abyss: Genesis will remove all spawned locusts without creating items to replace them.
  • Teleport! Teleport! / Teleport 2.0 Teleport 2.0 / Telepills / Teleport Cards: Should such items/consumables be obtained in the Genesis room, they can be used to circumvent the forced floor skip.
    • In the case of pills, unidentified pills should only be popped after taking all of the items, for the Genesis room cannot be returned to after leaving.
  • Wild Card Wild Card: Can't activate Genesis.
