Cards are used in Paths: World of Adia to play the game, however, there is no deck. All cards start in your hand, and you gain and lose cards based on the Paths that form your class.
When you first create your character, you will choose a starting class. For example, if you were to choose the Paladin, this would be your starting class. From there you would gain the first 3 root Paths that make up the Paladin: Combat, Religion, and Faith. These will be your starting Paths.
Over time you can purchase new Paths with Path Points after gaining XP when completing adventures through Solo Adventures or within classic group play with a Game Master.
As you unlock new Paths, your hand of cards will change, meaning as a Paladin for example – you could have more Utility and Action cards than Spell cards.
The way cards are played is based on rounds. There are 6 phases within 1 round. At the end of the round (after the sixth phase) all cards that were used return to your hand. You may also play a Refresh card before the round ends and place all cards previously used in recent phases, back to your hand.
You may also play with homemade cards, print these cards out, or use the official Paths: World of Adia Cards as seen above. If you’re feeling up to a challenge, you can also not use the cards at all and play using “Theater of the mind”. This is where you would declare what you’re doing (such as an Action or a Utility) and then performing and describing what you’ve declared, keeping track of this in your mind.
