Binding of Isaac: Rebirth Wiki

Added in Repentance

Adoption Papers is an unlockable trinket added in The Binding of Isaac: Repentance.


  • Shop Shops and Black Market Black Markets now sell familiars instead of the usual item selection.
    • The familiars are chosen from the Baby Shop item pool.
    • While holding the Adoption Papers, the familiars are discounted to 10 coins. If the papers are dropped, they cost 15 coins.


  • A shop that has already been entered will not have its item selection changed, nor will dropping the papers revert them to normal.
  • In Greed Mode, only the shop pool item is replaced with a familiar and discounted.
    • This also applies to all shop pool items when playing as Tainted Keeper Tainted Keeper. Familiars spawned from the Treasure Room pool remain unaffected.
  • Familiars that appear in both the Shop pool and Baby Shop pool (Buddy in a Box Buddy in a Box, King Baby King Baby, etc) will be discounted by Adoptions Papers even if the shop was visited before the trinket was held.


  • Steam Sale Steam Sale: Both of the discounts stack, selling familiars for 5 cents.


  • Chaos Chaos: Chaos takes priority in item selection. However, items will still be discounted.
  • Keeper's Box Keeper's Box: Does not affect Keeper's Box' items, meaning both familiars and shop items can be purchased in tandem over the course of a run.
  • The Stairway The Stairway: No effect on the Angel shop.
