Tainted Isaac can only hold 8 passive items at a time. Tainted Isaac's current 8 passive items are visible in the top-left corner of the screen, with one highlighted by a white square. Upon picking up a 9th passive item, the currently selected item will be dropped on a pedestal in front of Tainted Isaac. The swap key can be pressed to cycle which item is selected.
Additionally, all re-rollable item pedestals, Shop items, and Devil deals will cycle between two items for the player to choose from. Whichever item is currently visible when the item is picked up will be the one selected. Once an item has been picked up it will no longer cycle between items.
Void is extremely powerful with Tainted Isaac. Health ups and items that give one-time effects (such as Booster Pack) can be traded out for a more useful item and then voided for stat upgrades.
Birthright gives Tainted Isaac four more item slots, without taking up an item slot itself.
Due to the passive item limit, any items that can give stat upgrades independent of the item (such as Candy Heart or Death's List) are very useful to provide Tainted Isaac with stats he otherwise would not have.
Marbles and Mom's Box can be used to generate and swallow trinkets for passive bonuses.
Eden's blessing grants a random item at the start of your next run, even if you are to drop it and not finish your run with it.
