Greed Island guide
Greed Island Card System Guide
The Greed Island card system is built around two linked ideas: objects can become cards, and cards are governed by rules. Rank and limit describe scarcity; Book organizes possession; Gain releases a card back into usable form.
Use this guide with the card list and category pages. It explains the rules in plain language and links to cards where the rules become concrete.

Specified slots and free slots
Specified slot cards are the completion set, while free slot cards hold supporting objects and ordinary finds. The distinction matters because a card in the wrong place may not contribute to completion.
Rank
Rank is a rarity signal. Higher ranks such as S and SS usually point to cards that are harder to obtain, more limited, or more important to the game-clear path.
Limit
Limit controls how many copies of a card can exist in cardized form. This prevents the rarest rewards from becoming common and gives players reasons to race, trade, steal, or protect cards.
Book
Book is the interface that stores cards, shows slots, and makes the rules visible. It is the reason the card collection feels like an organized game system inside the story.
Gain
Gain is the command that releases a card into its item or effect form. It connects the card list to practical outcomes such as healing, travel, treasure, and risk.
Card transformation
Cards such as Fake and other manipulation spells show that form is part of strategy. Transforming, copying, reverting, or protecting card state can matter as much as obtaining the original card.
