    • The priority order of hearts that will be consumed is: one heart container, one bone heart, and two soul hearts.
  • After using Magic Skin, if Isaac is not currently holding it, Magic Skin has a chance to replace any item that spawns in the future.

Notes[ | ]

  • If using Character Magdalene iconMagdalene with Collectible Birthright iconBirthright, Magic Skin won't disappear until you have 18 or more broken heart containers.
  • Character The Lost iconThe Lost and Character Tainted Lost iconTainted Lost will be able to use the item once, after which it disappears. The item's chance of replacing later items does not trigger, making it equivalent to Collectible Mystery Gift iconMystery Gift.
    • An extra item cannot be spawned when used with Collectible Car Battery iconCar Battery.
  • Character Keeper iconKeeper and Character Tainted Keeper iconTainted Keeper gain a broken coin container, reducing their effective health by 1.

But if they have Collectible Deep Pockets iconDeep Pockets and Collectible Greed's Gullet iconGreed's Gullet, or Mother's KissMother's Kiss, they can use it more than 2~3 times.
      • Although they can have 13 or more coin hearts in some environment, they can only have a maximum of 12 broken coin heart containers. They will die only once all coin hearts are gone, causing Magic Skin to disappear.
  • If either Character The Forgotten iconThe Forgotten or Character The Soul (Character) iconThe Soul has 6 broken hearts by using Magic Skin, this item will disappear and they will instantly die. However, swapping characters right after one of them reaches 6 broken hearts can prevent them from dying, but permanently disable the one using it.
  • Character Tainted Lazarus iconTainted Lazarus is able to find Magic Skin while Character Dead Tainted Lazarus iconDead Tainted Lazarus is carrying it, and vice versa.
  • Reaching the broken heart limit by using ? Card? Card or Wild CardWild Card won't cause Magic Skin to disappear. This is especially useful when playing as any of the 3 above characters.
  • Using Magic Skin after touching the White Fire PlaceWhite Fire Place in DownpourDownpour II/DrossDross II, or while using the Soul of the LostSoul of the Lost, will still add broken hearts for when the character is revived.

In-game Footage[ | ]

Trivia[ | ]

  • Magic Skin originates from the Antibirth mod.
  • The item is a reference to the book by French novelist Honoré de Balzac called La Peau de chagrin, known in English as The Wild Ass's Skin. In the story, the main character finds a talisman made of donkey skin that grants wishes, but each wish causes the talisman to become smaller, as well as his lifetime. He attempts to get rid of the skin, but it always finds a way to return to him.
    • The item's pickup quote, "All your desires fulfilled", is the first sentence written on the skin in the novel.
  • This also may be a reference to the goatskin Jacob uses to trick his father Isaac into thinking he was Esau, thus giving him his blessing along with the divine right God had promised Abraham (Isaac's father), which included inheriting the promised land and having his bloodline bring forth the Messiah.
