Extra hearts from masks and held items now stack
A mask and a held item that each grant extra hearts now give both bonuses, and removing one keeps the other.
- Extra hearts from a mask and a held item now stack: wear the Nightfall mask while holding a +3 heart item and you get both bonuses, +6 in total.
- Taking off the mask or putting away the item now removes only that bonus, so the other one's hearts stay with you.
