Deck of Many Things
Wondrous item, legendary
Usually found in a box or pouch, this deck contains a number of cards made of ivory or vellum. Most (75 percent) of these decks have only thirteen cards, but the rest have twenty-two. (Our deck here has 22.)
Before you draw a card, you must declare how many cards you intend to draw and then draw them randomly. Any cards drawn in excess of this number have no effect. Otherwise, as soon as you draw a card from the deck, its magic takes effect. You must draw each card no more than 1 hour after the previous draw. If you fail to draw the chosen number, the remaining number of cards fly from the deck on their own and take effect all at once.
Once a card is drawn, it fades from existence. Unless the card is the Fool or the Jester, the card reappears in the deck, making it possible to draw the same card twice.
