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. The three possible stat upgrades Keeper's Sack can give are +0.5 damage, +0.25 range, and +0.03 speed.


  • Every 3 coins spent will give boosts to a specific stat, going in the order of damage-range-speed. Buying 15 coin items give the same amount of stats as buying five 3-coin items.
  • Keeper's Sack works with anything that costs coins, including Devil deals/Black Market Black Markets as Keeper Keeper / affected by Keeper's Bargain Keeper's Bargain or A Pound of Flesh A Pound of Flesh, items or pickups created by Keeper's Box Keeper's Box, the Angel shop created by The Stairway The Stairway, and the second shop created by Member Card Member Card.
  • All stat upgrades are tied to the item itself; losing Keeper's Sack somehow will result in the loss of all obtained stat upgrades.
