Get Rival Books of Aster for PC

Rival Books of Aster is a strategy card game about deciphering four rival books to save your household and rule the plane of Aster. Each book is a separate translation of a single source that has been lost to time, and all four begin with the phrase, “Take me and hide me, for I am the one true light.”

Build your deck

You build custom decks from over 140 hand-illustrated spells and characters. Each spell is also a page in a living story book that translates itself and reveals its secrets as you play. The game has an easy-to-use deck-builder and offers a different take on familiar game mechanics.

Battle other players

You can practice in Training Levels, fight against AI or use PvP matchmaking to compete with other players. PvP includes a ranking system.

Starter decks and expansions

There are four Starter Decks, each associated with a distinct art style:

• Heptameron
• Theurgia Goetia
• Grimoirum Velum
• Pauline Art

Four Expansion Packs add spells and characters and require the corresponding house’s Starter Deck:

• Heptameron Expansion Pack
• Theurgia Goetia Expansion Pack
• Grimoirum Velum Expansion Pack
• Pauline Art Expansion Pack

The game does not use randomized booster packs. You can play for free with a Starter Deck of your choice, and the Expansion Packs contain known quantities of cards.
