The Codex
Everything you can field, carry, wear or open with — read off the game's own data, not a marketing summary of it. What isn't listed here you'll have to earn on the board.
Pieces
The six you know, and the rest of the roster you earn.
Enchantments
Worn by one piece at a time — two, if it's the Mage.
Consumables
Spent once, from the corner of the board.
Openings
How you walk in. Every run starts with one of these.
