Binding of Isaac: Rebirth Wiki

Added in Afterbirth

Restock is a passive item added in The Binding of Isaac: Afterbirth. All characters start with Restock in Greed mode.


  • Upon purchasing an item from the Shop Shop, a new purchasable item is added to the store's inventory.
  • Removed in Repentance Drops 3 random pickups around Isaac.
  • Added in Repentance Outside of Greed Mode, the restocked item's cost is increased after each purchase.
    • For items, the price increase is 2 coins times the number of purchases. For example, an item starting at 15 cents would next be +2 to 17, then +4 to 21, +6 to 27, etc. The cost follows the formula 15+n(n+1) with n being the number of times restock has triggered.
    • For everything else, the price increase is 1 coin times the number of purchases. For example, a heart starting at 3 cents would be +1 to 4, +2 to 6, +3 to 9 etc. This follows the formula (original price)+(n(n+1))/2
    • The increase is not affected by discounts occurring naturally or through Steam Sale Steam Sale: costs will increase at the same rate, though the base price is still discounted. Once the item's cost goes over what it would naturally be, the price is no longer highlighted red.
    • The maximum price is 99 cents.
  • A small restock icon appears under the map, just like Treasure Map Treasure Map, Blue Map Blue Map, The Compass The Compass Added in Repentance and any active curses.



  • Removed in Repentance Steam Sale Steam Sale x2: Items can be infinitely bought from shops.

    • Added in Repentance If a Lil' Battery Lil' Battery is on sale, Isaac can buy a lot of items before the prices become too high in that shop.
  • Chaos Chaos: Restock is affected by Chaos, and can be used to obtain otherwise rare items.
    • Removed in Repentance Chaos + Steam Sale Steam Sale x2: Items can be bought infinitely, allowing Isaac to theoretically obtain every item in the game.
  • Added in RepentanceKeeper's Box Keeper's Box: Items spawned by the box are affected by Restock. Curiously, Restock's price increase on buying an item does not trigger making it easier to buy more items.
  • Added in RepentanceMember Card Member Card: Items bought in the separate shop will also be restocked.
