Item Beggar is a machine in Potato Packs, a mod for The Binding of Isaac. It is part of the Potato Pack 4 submod.
When Isaac bumps into this beggar, a list of Isaac's items will appear. Selecting an item from the list and pressing the drop input or CTRL button will make the beggar take the item.
After taking 2-3 items, the beggar will drop an item from a variety of possible item pools including Devil Room, Angel Room, Secret Room, Library, and Curse Room.
It disappears after dropping 3 items.
