Every Wild Hunt animal is represented by a Knowledge Card. The cards can be upgraded to provide passive bonuses during hunts.
All Knowledge Cards can be viewed in the Album. It is also where they can be upgraded. Every upgrade will require a player to have enough Knowledge Points for the Knowledge Card they want to upgrade. The higher the Knowledge Card level is, the more Knowledge Points it will require for another upgrade. All upgrades cost coins. Every higher-level upgrade will require more coins.
