Binding of Isaac: Rebirth Wiki

Mom's Eye is a passive item.

Effect[ | ]

  • Gives Isaac a chance to shoot a tear out of an eye on the back of his head.
  • (except in Rebirth) This item belongs to the Yes Mother?Yes Mother? set. Collecting three items from this set will transform Isaac into his mother.

Notes[ | ]

  • (except in Repentance) The chance to shoot an extra tear depends on the luck stat, and the formula used to determine the chance is:
    • At base luck (0), the chance is 50%, maxing out at 100% at 2 luck.
  • (in Repentance) The chance to shoot an extra tear depends on the luck stat and is based on this formula:
    • This means that the chance starts at 50% at 0 luck, minimizes at 0% at -5 luck, and maximizes at 100% at 5 luck.

Trivia[ | ]

  • (in Afterbirth † and Repentance) Mom's Eye's appearance was changed in Booster Pack#5.
  • The item is based on the adage that a mother has an eye on the back of her head, and is thus always able to see what her child is up to.
