Changes: Transformations

Revision as of 21:08, 2 December 2015

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

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

Notes

Activated items (e.g. Guppy's Head) only need to be touched in order to count. Keeping them, or even activating them once, is not required.
Rerolling items with a Dice Room, the D4, or the D100 will not remove progress towards the transformation.
Transformations can be combined with each other, keeping the effects of any and all transformations with no effects overriding others.
Transforming into Beelzebub for the first time will unlock the Lord of the Flies achievement.
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.

Trivia

There are two transformations in the base game and nine 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.
Rebirth introduced Beelzebub as the chronologically second transformation. It is so far the only transformation that unlocks an achievement.
