Technology

Technology works like a card deck. Each nation will be dealt some technology cards from the top of the Draw Pile and may choose one of them to research. The technologies that were not chosen as well as any newly unlocked technology will be placed in the Discard Pile. Once the Draw Pile is empty all cards from the Discard Pile will be shuffled into the Draw Pile. The game may recommend certain technologies to research, indicated by a star on the top-left of the card. Nations that have a leader with the Scholar archetype will be able to redraw once per year.

Certain technologies may unlock a Bonus Card. Bonus Cards are minor technologies that are lost permanently if not researched when the card appears.
