The Credit Card is a special card.
- Using the Credit Card in a Shop instantly removes the cost of all items in that shop, allowing Isaac to take all of them for free.
- Using the Credit Card in a Devil Room or Black Market allows Isaac to take all the items without any health cost.
- Taking Devil Room items with the Credit Card does not prevent Angel Rooms from appearing.
- Free items will remain free, even if Isaac leaves the current room.
- Works with the Blank Card, allowing Isaac to purchase all items from every shop, if used correctly.
- Using the Credit Card in a Shop prevents Restock from working in this shop only. However, Restock Machines will work, creating new items.
