Added in Repentance

Mother's Kiss is a trinket added in The Binding of Isaac: Repentance.


  • Grants one heart container while held.
    • This heart container will be filled the first time the trinket is picked up.


  • If the only heart container Isaac has is the one given by Mother's Kiss, the trinket will be destroyed if the heart container is traded/consumed.
  • If Isaac drops the trinket while he only has one heart container for health, he will have no health and die instantly.
    • This also means that using 0 - The Fool? 0 - The Fool? card will do the same, even if he has soul hearts.
  • The extra red heart container can exceed the maximum coin heart container limit of Keeper Keeper and Tainted Keeper Tainted Keeper, allowing them to obtain more than 3 or 2 coin hearts, respectively.
  • The heart added is a soul heart for ??? ??? and Tainted Bethany Tainted Bethany, and a black heart for Dark Judas Dark Judas and Tainted Judas Tainted Judas.
    • Using The Fool? card as one of these characters while holding this item will kill you instantly, as it drops the trinket, removing the last half soul heart that you normally would remain with.
  • The Forgotten The Forgotten will always get a bone heart regardless of whether the body or the soul picked up the trinket.


  • 15►Guppy's Paw Guppy's Paw: The trinket will be consumed but you get to keep the soul hearts from the conversion.
  • 15►Mom's Box Mom's Box: Adds 2 heart containers.
  • ??? ???/Tainted Bethany Tainted Bethany/Tainted Judas Tainted Judas/Dark Judas Dark Judas: If Mother's Kiss is picked up while having 12 Soul/Black Hearts, Mother's Kiss will not trigger until damage is taken. However, if only half a heart of damage is taken, Mother's Kiss will immediately restore the health back to a full 12 but believe its effect failed due to not restoring a full heart's worth, allowing it to trigger again and again until a full heart of damage is taken, after which it will cease taking effect. If combined with 15►The Wafer The Wafer, this makes any of the above-mentioned 4 characters virtually invincible as long as their health is not reduced in any way through Devil Deals, Health Down pills, etc.[1]

In-game footage[]


Bug Bug! Dropping Mom's Box will not remove the second heart container until the trinket is dropped.
Bug Bug! If multiple copies of the trinket are smelted as The Keeper or Tainted Keeper, the maximum limit of 12 coin heart containers can be exceeded, granting invisible coin heart containers that work normally in the background but are not displayed on the HUD.
Bug Bug! Dying and respawning with 15►Dead Cat Dead Cat will respawn you with only 1 heart container, meaning you will instantly die if you drop the trinket.
