Transformations

From Binding of Isaac: Rebirth Wiki
Jump to: navigation, search

Transformations alter Isaac's appearance and grant him special abilities.

A transformation occurs when obtaining at least three different items from a particular set of items.
These collectibles always share a particular theme that corresponds with the transformation.

Requirements

  • Items only need to have been acquired once in order to count.
    • Removed in Repentance Duplicate items (like those acquired from Added in Afterbirth15►Diplopia Diplopia) do not count toward transformations when picked up. Only the first instance of an item Isaac owns will count.
    • Added in Repentance Duplicate items are all counted.
    • Activated collectibles (e.g. 15►Guppy's Head Guppy's Head) can be picked up once and then swapped away with another without any loss to transformation progress.
  • Removed in Repentance Rerolling items with a dice room, the 15►D4 D4, or the 15►D100 D100 will not remove progress towards the transformation.
    • Added in Repentance The transformation will be lost if the items required are rerolled or otherwise lost, eg. 15►Sacrificial Altar Sacrificial Altar.
  • Added in Afterbirth Familiars gained from 15►Cambion Conception Cambion Conception or 15►Immaculate Conception Immaculate Conception do not count towards transformation progress.
  • Trinkets do not count toward progress for any transformation, with the sole exception of Added in RepentanceKid's Drawing Kid's Drawing that counts for Guppy transformation.
  • Pills only count toward Adult and Stompy, they do not count toward progress for any other transformation.
  • Added in Repentance When playing as Jacob and Esau Jacob and Esau or Tainted Lazarus Tainted Lazarus only the character that picks up an activated item first gets the progress for related transformations, however both characters in the set may undergo the same transformation if they both collect the remaining required set items left in the item pool.
  • Added in Repentance Tainted Isaac Tainted Isaac will not lose a transformation nor progress towards it if he replaces an item that counts towards that transformation.

Notes

  • Transformations can be combined, keeping the effects of all transformations with no effects overriding others.
  • Transforming into Beelzebub for the first time will unlock the Lord of the Flies achievement and Added in Afterbirth †15►Angry Fly Angry Fly.
  • Since none of the Afterbirth transformations unlock an achievement or item, attaining them is not required for 100% completion of the game in terms of achievements. Added in Afterbirth However, this is only true if you unlocked 15►Mom's Contacts Mom's Contacts on Rebirth, as the Yes Mother? transformation will happen once you collect three Mom items on Afterbirth and Afterbirth †.
  • Many of the Afterbirth transformations override the charge animations of items such as 15►Monstro's Lung Monstro's Lung and 15►Brimstone Brimstone, potentially making them more difficult to use.
    • Added in Afterbirth † There is now an option to show a charge bar that floats above Isaac.

Trivia

  • There are two transformations in the base game, nine more in the Afterbirth DLC, and four more in the Afterbirth † DLC.
  • In the original The Binding of Isaac flash game, the transformation into Guppy was the only one available, making it chronologically the first.
    • The Eternal Edition of the original The Binding of Isaac game added another transformation that turned Isaac into an angel after gaining 7 heart containers from eternal hearts.
  • Rebirth introduced Beelzebub as the chronologically second transformation.
  • The original name for the Beelzebub transformation was Lord of the Flies.
  • The reason no new transformations have been added to Repentance is because Edmund and the dev team do not like them. If any new transformations were to be added, they would be purely visual.[1]
