Binding of Isaac: Rebirth Wiki

Added in Repentance

Keeper's Sack is an unlockable passive item added in The Binding of Isaac: Repentance.


  • Gives Isaac stat upgrades when he buys items/pickups from shops.
    • The three possible stat upgrades Keeper's Sack can give are +0.5 damage, +0.03 speed, and +0.25 range.
    • Isaac will receive each of these stat upgrades in turn for every 3 cents spent (first damage, then range, then speed, then back to damage, and so on). This means that it doesn't matter how money is spent, just how much total money is spent. For example, buying three 5-cent items will give Isaac the same stats as if he bought a single 15-cent item instead.
  • Spawns three coins and a key on pickup.



  • Steam Sale Steam Sale: As items/pickups cost less money, Isaac will gain fewer stats for making the same purchases.
  • Store Credit Store Credit: Anything bought will not give stats.
