MOC ARCANA

The Campaign: 96 duels to the Arcana Vault

At the bottom of Cronos lies the Arcana Vault, and around it swims The Whale, the oldest holder of all. 7 keys open the Vault. To get them, you will cross every faction of the chain, one chapter at a time.

The Campaign is the story mode of MOC ARCANA: 8 chapters of 12 acts, 96 duels against the Arcana AI, each one a little harder than the last. It runs in your browser, with the cards you collect.

How the Campaign works

8 chapters, 12 acts each7 chapters, one per faction, from the easiest to the hardest. Then the finale, where all of them stand between you and the Vault.
A key per chapterBeat the boss of a chapter and you win its key. 7 keys, then the last door.
An AI that fights harderIn the first chapters, you face the standard Arcana AI. The last chapter brings the master AI: no mistakes, a full battle plan, every trade weighed.
Your own deckYou play with a 40-card deck built from your collection. Every act shows its painted scene and a line of story before the duel.

Chapter I · The Mist Market

In the mist, stall keepers whisper offers you cannot refuse. None of them are alive. The Mist Market is where every player's Campaign begins: ghosts who sell dreams, peddlers whose bargains cost a little more than CRO, and somewhere behind the lanterns, the stall that holds the Pearl Key.

Chapter II · The Molting Grounds

Further down the chain, memes shed their old skins and come back stronger. In the Molting Grounds, empty skins still move on their own, and every card you beat may return in a new form.

5 more chapters, then the finale

The next five chapters stay sealed until you reach them: 5 factions, 5 bosses, 5 keys. Their scenes and their stories open one act at a time, as you win.

Then comes the finale. Below the last faction, the champions of every faction guard the way to the Arcana Vault, and The Whale waits.

"I was here before the first block. I will be here after the last."The Whale

Tips for the first chapters

  • Learn the rules in Free play. A free duel against the Arcana Apprentice teaches summoning, sacrifices and battles in a few minutes. Game rules
  • Build around a faction. Many effects reward a deck built around one faction. The seven factions
  • Keep small Tokens. Level 1 to 4 Tokens need no sacrifice: they are what lets you summon your giants later.
  • Watch the Dead Wallet. Fantasma brings its cards back from the discard pile. Do not assume a destroyed card is gone.
