Each player, including the GM, can decide whether they want to use cards or dice. If you decide to use cards, you need part of a poker deck (cards A-6 from each suit, plus one of the jokers) for every one to three players, and if you decide to use dice, you need 24 dice in four colors (6 each) plus one black die for every one to three players, and a cloth bag to put all the dice inside.
The system is balanced for both so you can all use cards, all dice, or mix and match according to personal preferences and you will have a fairly similar experience.
After many, many playests, we can assure you it is equally entertaining either way. We personally enjoy playing with cards more, but oftentimes we find ourselves running the game with dice and it is an equally rewarding experience.
If you are using regular poker decks and taking only the cards you need (cards numbered A-6 from all suits + one joker), you need at least one deck per 2-3 players. A good number is one deck per 2 players, and if the number of players is odd then don't count that last player.
If you are using our DCA deck packs, each pack contains 2 decks, so with one pack you can play with up to 5 players, and with 2 packs (which is what is included in the GM's Kit and Full package pledge levels) you have enough for 9-10 players, which is probably more than most people will ever need. These cards are just four suits (exploration, combat, magic, social) each numbered 1 through 6, plus one joker, and each card has a different illustration from the game.
You need 24 six-sided dice in four colors (6 dice of each colour) plus one black die for every one to three players, and a cloth bag to put all the dice inside.
So if you are just one or two players in a group that otherwise plays with cards, you are good with one set of 25 dice. If you are a group of 4-5 players you should use 50 dice (two sets as explained above); and if you are 6-9 players you should use 75 dice (three sets as explained above).
This may seem a bit costly, but we've found it isn't so. There are plenty of coloured six-sided dice sets in Amazon for a decent price, we consistently find packs of 50 dice for about €10 (which is right about what a cool polyhedral dice sets costs anyways). And if you are lucky, your FLGS may stock decently priced dice sets too, so go there first just in case!
There are small dragons that accept a single rider, and bigger dragons that can take an entire party or even a big crew. And of course, you may end up having to fight a dragon at some point or another, but we do not recommend it at all. Do it at your own risk :’)
