Ederon has 6 types of cards plus the class card. They can be divided into equipment and techniques.
Equipment: Lingering cards. They require a specific free slot to be played. Hands, body or trinket.
Techniques: Expendable cards. After resolving they go to the discard pile. They don’t require any free slot as they are played on the action field.
Class: When equipped on the class slot, they define which cards can be played. The class card can only be equipped in your equip phase and after doing it your turn ends.
