Grimoire

The Grimoire is a database within Destiny. Entries were unlocked through playing the game in the form of "Grimoire Cards." Grimoire entries do not feature in Destiny 2 as the story will be instead told in-game. Following the release of Destiny 2, the Grimoire feature was removed from the Bungie web site and the Destiny app. Cards and their corresponding bonuses are still unlocked in game but they can not be viewed.

The list of Grimoire entries is sorted into six main categories—Guardian, Inventory, Allies, Enemies, Places, and Activities. Each of these categories has a number of sub-categories. Grimoire cards are earned through various ways, such as completing a Story mission or Strike, playing a match on a Crucible map, reviving a Dead Ghost, discovering a Calcified Fragment, or finding a Dormant SIVA Cluster. They are also unlocked by earning kills with specific weapon types; each rank allows upgrading that weapon type to be faster. Last but not least is a series of redeemable codes which can be inputted into Bungie's website, which unlocked cards.
