Sacrifice your first card to the Soulstone. Every journey begins with letting something go.

Wake the Soulstone

Transcend for the first time and claim a class. Your soul outgrew its vessel.

First Class

Evolve your companion into its combat form. The materials you feed it now decide the warrior it becomes.

Blooded Beast

A companion reaches its true form, and you give it a name that will echo across every world you build. Only true forms reach their full potential — and only named ones are remembered.

True Name

Defeat the Goblin Shaman on the fifth floor. The dungeon is paying attention now.

Shaman Slain

End of the demo. The portal remains — step through for a reshuffled world with everything you've earned. The full game opens further. But your next world is already waiting.

The First World

Soulstack

Idle card RPG on a table. Drag cards onto each other to explore, gather, craft, fight, transcend, and feed your pet. 200+ weapon recipes (only ~40 are worth keeping), 140 pet evolutions, 12 prestige classes.
