Favorite Curse or Cursed Item.
This item is not necessarily a curse but it certainly can be. The Deck of Many Things. The player announces how many cards they are going to draw, between 1 and 3. Then they must draw that many cards no matter what happens to them from previous cards. None of the cards outright kill you but they do have the potential to put you in a very dangerous situation. The flip side as to why it may not be considered cursed is that the deck can help you. It could make you higher level, give you items, or even gold.
