Might & Magic: Duel of Champions is a tactical card game set in the fantasy world of Ashan, where all Might & Magic games are taking place since Heroes of Might and Magic V. Despite a similar premise, it is not a sequel to Arcomage. Two players face off with a deck containing different sorts of cards: heroes, creatures, spells, fortunes and events. Every turn, the players gain resources allowing them to play one or more cards, the goal being to eliminate the enemy's creatures in order to attack his Hero directly. When a Hero's health is reduced to zero, his player loses the match. The game features the factions and art style seen in Might & Magic: Heroes VI. Through victory, the player will gain experience points, gold and seals, the latter two allowing him to purchase more decks and cards. The game adopts a free-to-play model, so it's also possible (though not mandatory) to use real-world money to acquire more in-game currency.
While the online multiplayer mode is the heart of the game, Duel of Champions also features a single-player campaign, telling the story of the Windswords, a company of mercenaries confronted to the sinister threat of the Nethermancers, the wizards of the Void.
