The Womb

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

The Womb is the fourth chapter of the game, unlocked after beating Mom. From the Womb onwards, all damage taken will do a full heart of damage to the player's health (unless the player has The Wafer), regardless of the source. Like The Depths/Necropolis, the Womb's second floor has a preset boss that will always be fought: Mom's Heart initially, and It Lives after beating Mom's Heart 11 times.

The Womb has two alternate floors. The Utero, which, unlike alternate floors before it, does not need to be unlocked, and the Added in Afterbirth Scarred Womb.

Notes[edit | edit source]

  • It is possible to access the Womb before unlocking it by using a Rune of Ehwaz or We Need to Go Deeper! on The Depths II.
  • Using the Rune of Ehwaz or We Need to Go Deeper on Womb/Utero II will lead you to Sheol, which will skip any of Mom's Heart's endings.
  • The Womb being mentioned in Isaac's last will as a "warm place" is a reference to how the inner human body temperature is quite high.
  • The Womb, And Utero both have a slight static filter covering the screen, possibly to represent heat.

Unlockable Achievements[edit | edit source]

  • Mama's Boy
    Mama's Boy - Beat chapter 4 without taking damage.

Music[edit | edit source]

  • The music for the womb is titled Viscera. The term viscera represents the internal organs in the body. The Utero shares this same track.
  • The music heard during the fight against Mom's Heart/It Lives is called Ventricide. Ventricide is a word made up of the Latin word for Heart, Ventricle, and the suffix -cide, which denotes the act of killing.
    • This has been confirmed by Edmund when he said it means something like "the killing of the heart". This is in theme with other similar boss tracks such as Matricide, Hericide, and Infanticide.
