I suppose the fun bit is coming up with how to usefully apply these illusions to your situation. This lich could be used to scare off your enemies, but it could also engage them in conversation, right? Perhaps even trick them into following it?
- I wanted to give each card an effect that had a clear use in combat. A few of these could be bad for the user, just like the Deck of Many Things. One of them - the Master - could even be deadly.
- I wanted to preserve the ability for players to think up clever ways of controlling their illusions. In the end, this worked best as an at-will artifact power, separate from the card powers.
As you'll see, it turned out very differently to the old Deck of Illusions. I think you'll find it useful in your games: our group's wizard used it to great effect throughout H3: Pyramid of Shadows, so I've had a chance to rebalance the powers after seeing them in play. Oh, and check out the lore for the Prince card - after all his adventures, I couldn't write this up without mentioning our own, friendly wizard at least once.
Lastly, if you do use it, make sure to drop me a line here and let us know how it went. It would really make our day to know our deck is being used at other tables!
