I have a long (and troubling) relationship with the "Deck of Many Things" there hasn't been a single DnD campaign I've ran where I haven't willingly introduced it...or it showed up on its own. Put simply, I have a deck of cards with my other DnD things that I carried for a reason. So today's knockoff (I prefer the phrase "inspired by"), "The Deck of Wonders," should come as no surprise - to my players at least.
Deck of Wonders
Resembling a deck of cards, this artifact can be the bane or blessing of a given delver. Before any cards are drawn, the the drawer must specify how many he wishes to pull and then he must pull that amount. If he fails to draw the cards for whatever reason he can make a Will roll -10, failure means the cards draw themselves for him, success means he takes HP damage equal to a full multiple of his Hit Points times the number of cards he failed to draw.
• Hand of Fate: Every card drawn has either a beneficial or baneful effect. Permanent effects can be removed with a Remove Curse spell (GURPS Magic, p. 126) - though the effects resist with a skill of 35! Deck of Wonders with Cosmic origins cannot have effects removed except by the direct intervention of the gods. In most cases, the exact effect will be immediately known to the drawer unless noted otherwise thanks to a combination of a physical representation (the engraving) and a sudden flash of insight. See the chart below to determine the effect a given card bestows either with dice or a actual deck of cards.
• Whimsy: The deck doesn't remain in the possession of one person for long and is immune to any such effects from supernatural means or the like. Furthermore, it can never be taken as Signature Gear. Every month the deck remains in the same persons possession, make a unmodified Reaction Roll (for those with Weirdness Magnet, roll 1d, on a 1-3 subtract 3 from this roll; on a 4-6 add three instead) and consult the following chart:
Disastrous: As Very Bad, but also forces the owner to draw 1d-1 cards before it goes.
Bad or Very Bad: The deck disappears and takes $1dx500 worth of valuables with it. Adjust this for delvers with higher or lower Wealth levels!
Poor or Neutral: The deck disappears from the owner's possessions.
Good or Very Good: The deck stays...for now.
Excellent: It likes you. It really likes you. Not only does it stick around without requiring any more checks for 2d months, but you can add your full reaction modifier against it. This comes at a cost however, you gain Weirdness Magnet if you don't already have it, as the deck permanently warps your karmic field.
Weight: 1 lb.
Nothing says it needs to be a deck of cards. It could be a set of dice with ever-changing faces or a book that's blank until the page is turned and then the effect shows up. Any sort of random device is possible, consider a roulette wheel or even a board game.
