Latest revision as of 16:20, 23 June 2021

The Lost is a secret character.

The Lost starts with no health and cannot gain health by any means. Therefore, it will die from any damage taken.

  • Removed in Afterbirth The Lost starts with flight.
  • Added in Afterbirth / Removed in Repentance The Lost starts with flight, spectral tears, 15►D4 D4 (if unlocked) and 15►Holy Mantle Holy Mantle (after donating 879 coins to the Greed Machine).
  • Added in Repentance The Lost starts with flight, spectral tears, 15►Eternal D6 Eternal D6, and the effect of 15►Holy Mantle Holy Mantle (after donating 879 coins to the Greed Machine) This form of Holy Mantle is inherent to the character rather than being a starting item, and as such will be present when switching to The Lost in the middle of the run through the use of 15►Clicker Clicker, will not be present when switching away, and cannot be removed by any means.

3DS The Lost also starts with 15►D4 D4 (if unlocked).

Added in Afterbirth The Lost can activate the button in Greed mode without taking damage, in exchange of one coin less of the next wave's reward. The Lost can take devil deals and Black Market items for free.

  • Added in Repentance Devil deals and Black Market items are presented as choices. Taking one will despawn all other deals in the room.
    • Unlike other choices, devil deals cloned with items like Added in Afterbirth15►Diplopia Diplopia or Added in Afterbirth †15►Crooked Penny Crooked Penny will not be a choice. All copies can be taken.
    • The Lost can take every devil deal in the first room of the Dark Room Dark Room if the red chests are opened one by one.

Notes[]

  • Many of the game's items provide no benefit to The Lost; for example, those that affect health or trigger on taking damage.
  • Resurrection items like 15►Dead Cat Dead Cat will still work with The Lost.
  • Devil deals, while free, still count as making a deal with the devil and will prevent angel rooms from opening. Thus, a Credit Card Credit Card is still recommended, or getting Added in Afterbirth15►Chaos Chaos to acquire angel room items (except broken key pieces).
  • Added in Afterbirth † Isaac will be replaced by The Lost upon starting a third victory lap; however, Victory Laps do not allow the unlocking of achievements.
    • Removed in Repentance Since the Lost's Holy Mantle isn't intrinsic, the Victory Lap Lost will always die from one hit unless the player has explicitly found the Holy Mantle.
  • Removed in Afterbirth † If The Lost's Holy Mantle effect is lost while within a Curse room, closing the game, starting it up and then continuing the run will restore the Holy Mantle's charge, allowing The Lost to leave the room unharmed.
  • Removed in Repentance Using the D4 at all is not recommended as it will remove the Holy Mantle, making The Lost die in one hit.
  • Added in Repentance The Lost's Holy Mantle effect is intrinsic to the character once unlocked, and it can't be rerolled.
  • Added in Repentance The Lost starts with 15►Eternal D6 Eternal D6, even before it's unlocked.
  • Added in Repentance15►Holy Mantle Holy Mantle is intrinsic, but picking up another one does not double the effect.
    • Being innate, this holy mantle effect is not shown in the HUD nor in the pause menu.
    • It also cannot be re-rolled away.
      • Upon using the 15►D4 D4, the holy mantle effect will be temporarily lost. Leaving the room will regenerate the shield. (possibly a bug)
  • Added in Afterbirth / Removed in Repentance After reaching Womb Womb, The Lost becomes slightly easier to play, because the invincibility frames from 15►Holy Mantle Holy Mantle scale with the damage that would have been taken.
    • Added in Repentance Holy Mantle breaking only grants half a second of invincibility frames, regardless of the damage source.
  • Using the 15►IV Bag IV Bag will instantly kill The Lost even with the Holy Mantle.
  • Trinkets and Items like Added in RepentanceBrain Worm Brain Worm that can home-in and target enemies even at a distance are invaluable early game as you do not need to place yourself directly in the enemy's attack path and The Lost's spectral tears pass through most obstacles.

General Strategies[]

Main article: The Lost (Strategy)

Item Interactions[]

  • Added in Repentance15►Birthright Birthright: Prevents items with the internal tag nolostbr from spawning. In practice, this automatically rerolls most items that aren't beneficial to The Lost, namely ones that only give health, flight, and/or spectral tears or activate upon taking damage.

Added in Afterbirth Unlocking The Lost in Afterbirth[]

The Lost is unlocked by dying in a sacrifice room while holding Missing Poster Missing Poster.

  • Looking for Added in Afterbirth15►Mom's Box Mom's Box in shops makes finding the poster easier.
  • Added in Afterbirth15►Glitter Bombs Glitter Bombs, in conjunction with a large enough or infinite source of bombs (such as a Gold Bomb), have a small chance to drop trinkets, making it easier to find the poster.
    • Added in Repentance This method got nerfed, since Added in Afterbirth15►Glitter Bombs Glitter Bombs now have a cap on drops per floor.
  • It is technically possible to unlock The Lost while holding Mysterious Paper Mysterious Paper, although the probability is small since it only has a 1/4 chance to imitate the Missing Poster Missing Poster. 15►Dead Cat Dead Cat and other resurrection items could be useful for extra attempts.
    • Added in Repentance Since Added in Afterbirth †15►Divorce Papers Divorce Papers always drop Mysterious Paper Mysterious Paper and have a cheap craft for Tainted Cain Tainted Cain and his Added in Repentance15►Bag of Crafting Bag of Crafting, a new possible method has been found where you spam runs getting the Divorce Papers early and dying in the first Sacrifice Room you can find. Even with the small chance of getting the unlock with Mysterious Paper, the high number of runs in a short period of time can be worth it.
  • Even while holding Missing Poster Missing Poster, if Isaac happens to teleport while taking the last heart of damage, you will die without unlocking The Lost. This includes sacrificing on the spikes in the middle of the sacrifice room past 11 times.

Removed in Afterbirth Unlocking The Lost in Rebirth[]

The Lost is unlocked by dying consecutively with certain characters, with no other deaths. Deaths must be completed in the order shown here, and seeds can be used for the runs except for the last with Azazel:

  1. Isaac Isaac must die to a Mulliboom in Basement Basement or Cellar Cellar.
  2. Magdalene Magdalene must die to her own bomb in Caves Caves or Catacombs Catacombs.
  3. Judas Judas must die to any Mom attack in Depths Depths or Necropolis Necropolis. Being killed by any monster spawned by Mom will spoil the entire attempt at unlocking The Lost.
  4. Azazel Azazel must die to any Satan attack in Sheol Sheol. Being killed by The Fallen in the boss room or a Kamikaze Leech will spoil the entire attempt at unlocking The Lost. Being killed by using 15►The Bible The Bible doesn't count as a Satan kill.

The Lost will be unlocked after dying to Satan's attack.

Notes on unlocking The Lost[]

  • Multiple lives (for example, obtained by 15►Dead Cat Dead Cat) must be depleted before the intended death, as deaths while having extra lives do not count as a game loss.
  • Having any mods installed that triggers the mod flag will make The Lost unobtainable. To fix this problem, all mods have to be removed.
  • The game cannot be won as any character required to unlock it when unlocking it.
  • Champion versions of monsters and bosses will count for the death criteria.
  • Runs can always be safely reset.
  • Mom's Foot's stomp counts as explosive damage, which makes 15►Pyromaniac Pyromaniac a problematic choice when trying to complete Step 3.
  • Picking the wrong character while unlocking him doesn't mess up the unlocking process.[1]
  • Quitting and Restarting the game in the middle of the unlocking process doesn't mess it up.[2]
  • Picking up 15►Lazarus' Rags Lazarus' Rags, 15►Judas' Shadow Judas' Shadow, or 15►Ankh Ankh should be avoided. These items will revive the current character as a different one and therefore prevent the current unlock-step from being fulfilled.
  • Exploit: If you die during a required run, but hit the "start" button just as you die and reset before it shows the "Today I died" paper, it will not count as a death that spoils the run, instead it counts as a restart.

File Manipulation[]

By changing a file parameter, an unsuccessful try can be undone:

  1. Backup the file Options.ini found in the Documents\My Games\Binding of Isaac Rebirth by making a copy of it in the same folder.
  2. Open the original file with Notepad and change the SteamCloud parameter in it to 0. This will disable Steam Cloud gamesaves synchronization.
  3. After an unsuccessful try, delete the original file and rename the backup copy with the name of the original file: Options.ini
  4. Repeat steps 1 after each successful run until you unlock The Lost.
  5. When finished, open the original file and restore the SteamCloud parameter in it to 1. This will enable Steam Cloud gamesaves synchronization again.
