Completion Marks

From Binding of Isaac: Rebirth Wiki
(Redirected from Completion Mark)
Jump to: navigation, search

Completion Marks are earned by completing specific objectives in the Binding of Isaac: Rebirth. As you complete these objectives, the post-it note on the character select screen fills up with Completion Marks. If objectives are completed in Normal Mode, the Completion Marks are solid black. If objectives are completed in Hard Mode, the Completion Marks are outlined in red. If a Completion Mark is earned in Hard Mode without first earning it in Normal Mode, the game will count both the normal Mark and the hard mode Mark as unlocked. This means that completing a run in Hard Mode will earn you every secret along a particular path while completing it in Normal Mode will cause you to miss the Mom's Heart unlock.

In the main game, there are 6 unique completion marks, and each one comes in two varieties, adding up to 12 marks in total. Afterbirth introduced 3 more, bringing the total to 17, as Greed Mode only has one mark. Afterbirth+ introduced 1 more, as well as an additional mark for Greed Mode, bringing the final total to 20. Each mark has a character-specific unlockable secret associated with it, and there are 6 secrets per character in the base game, while there are 10 in Afterbirth and 12 in Afterbirth+.

In the base game Mom's Heart/It Lives is the only boss that has a character-specific unlock if you beat it in Hard mode instead of Normal mode, with one exception - Godhead, which is unlocked by beating every boss in Hard mode with The Lost. Therefore, it is not necessary to earn every Hard Mode Completion Mark to achieve Platinum God, only every Hard Mode Heart Mark, with The Lost as an exception. In subsequent DLC, every character has a co-op baby that can be unlocked for earning all of their Completion Marks on Hard Mode.

Notes[edit | edit source]

  • Added in Afterbirth As Greed Mode is a unique mode separate from Normal or Hard mode, it always appears on the completion note with the red outline otherwise found on Hard Mode marks.
    • Added in Afterbirth † This symbol is used to indicate completion of Greedier Mode, and the Greed Mode symbol is changed to be one without a red outline.
  • While it is possible to fight Mega Satan in the base game, Completion Marks for defeating him and their respective unlockables are only available in the subsequent DLC.
  • In the base game, Godhead GodheadCollectible Godhead icon.pngIncreases damage and range while reducing tears and shot speed. Grants homing tears and tears gain a damaging halo. is unlocked by defeating Mom's Heart, Isaac, ???, Satan, The Lamb, and Boss Rush on Hard Mode as The Lost.
  • Some items and trinkets transform Isaac into another character. All completion marks earned in that run from the moment of death onwards will count towards the new character, not the old.
    • Judas' Shadow Judas' ShadowCollectible Judas' Shadow icon.pngAdds an extra life; upon death, it respawns Isaac as Black Judas with only two black hearts. will transform the current character into Dark Judas upon death. Dark Judas is considered the same character as Judas by the game and can earn all of Judas' Completion Marks.
    • Ankh AnkhCollectible Ankh icon.pngUpon death, the player will respawn as ??? with 3 soul hearts. will transform the current character into ??? upon death, and Broken Ankh Broken AnkhTrinket Broken Ankh icon.pngWhen held, Isaac has a chance to be revived as ???. Can occur multiple times in the same run. has a 22.22% chance to transform the current character into ??? upon death.
    • Lazarus' Rags Lazarus' RagsCollectible Lazarus' Rags icon.pngUpon dying, resurrect as Revived Lazarus with one heart container and Anemic item. will transform the current character into Lazarus Risen upon death. Lazarus Risen is considered the same character as Lazarus by the game and can earn all of Lazarus' Completion Marks.
    • Added in Afterbirth Missing Poster Missing PosterTrinket Missing Poster icon.pngIf Isaac dies in a Sacrifice Room, a puzzle piece will appear on his last will (Added in Afterbirth and unlocks The Lost). Added in Afterbirth Revives Isaac as The Lost if unlocked. The Missing Poster then disappears. will transform the current character into The Lost upon death.
    • Added in Afterbirth †Clicker ClickerCollectible Clicker icon.png6 roomsTransforms Isaac into another random character. will transform the current character into a random character upon use.
  • With Clicker and a reliable method of reaching the I AM ERROR room (like Teleport 2.0 or Undefined, held with a Schoolbag), The Void can be repeated endlessly and cleared with every playable character in a single run.
    • Substituting the item to reach the I AM ERROR room with a Forget Me Now and some method to duplicate it endlessly (like Crooked Penny combined with Glowing Hour Glass to rewind failures), this can be applied to any floor and boss in the game, allowing any completion mark to be obtained with every character in a single run. Moving Box will also be necessary to bring all of the required items with you on each reset.
      • The Boss Rush requires the additional duplication of a Mama Mega! to repeat endlessly.
      • Mega Satan can only be repeated with the addition of other unlimited items that can unlock the door, such as a duplicated Get out of Jail Free Card, Dad's Key, or Mr. ME!, because the key disappears after a single-use. Mega Satan also has a 50% chance of automatically ending the run upon defeat, so it is only recommended to focus on that completion mark after finishing all other possible marks as the desired characters.
      • Completion marks for Satan and The Lamb are still mutually exclusive with completion marks for Isaac (Boss) and ??? (Boss). This means that a minimum of two runs are required to obtain every character's completion marks using this strategy.
      • This strategy does not work for Greed Mode completion marks. While most of the required items can be acquired by exhausting the mode's normal item pools, Moving Box is completely unobtainable (except in the extremely unlikely case that Eden begins with it.) A maximum of 3 Greed Mode completion marks can be obtained in a single run using 2 or more items that revive you as a different character, alongside 2 Forget Me Nows and a Schoolbag to hold them.
      • Getting all these items in a single run usually requires the use of a strategy to create infinite items and exhaust the item pool, like Blank Card combined with Jera. While this can be time-consuming to achieve in a single run, it can save you a great deal of time and additional runs if you are aiming for 100% completion.
    • Substituting Clicker with items that revive you as another character upon death will allow you to get the extra completion marks for The Lost, ???, Lazarus, and Judas, but will not allow for completion with every character as the Clicker does.
