Wrath of the Righteous kicks off the new season of Organized Play for the Pathfinder Adventure Card Game from Paizo Publishing. In this season, players will do battle against all manner of demons and cultists as they work to close the demonic and hellish Worldwound (probably want to get some triple anti-biotic on there). The demon lord Deskari will stop at nothing to take over the world and only the PCs are there to stop him and his seemingly endless tide of minions.
The new Wrath of the Righteous box is a new core box game, being able to be played all on its own without having to own other Pathfinder Adventure Card Game sets. The set comes with over 500 cards of all types, from boons to monsters to abysmal barriers. It also has seven character classes, several of them are brand new, such as the arcanist, summoner, inquisitor, and cavalier (being from Cleveland is not a prereq.). There's also the Worldwound Incursion Adventure Deck, which is 110 cards strong and is the starting-off point for the Wrath of the Righteous Adventure Path. And because you can never have enough dice, there's a set of 6 in there (along with the first-ever D20 for the card game).
This new set ties in with the promotional cards from Wizkids' Pathfinder Battles: Iconic Heroes miniatures sets. So you can use those cards as part of your player deck as well.
