Crafting menu. Available recipes are on the right, ingredients needed for crafting on the left.
To survive in this world you need special objects, like tools, camp upgrades and clothing. Those objects need to be crafted.
The knowledge for crafting an object can be bestowed on the player after offering food or gold nuggets at the knowledge altars at the Mystical Monuments.
You find the the bestowed knowledge in your knowledge docket. This docket used to have a capacity for 12 different "blueprints". There used to be more possible object to create than capacity in the docket. Therefore it was useful to forget a "blueprint". The knowlege used to be saved on a sheet of paper and relearned later when needed.
At the moment all the recipes are available indefinitely from the time they are learned.
Selecting one "blueprint" in your knowledge docket will give you the components list to the left. The components list will give you a view of the needed items. While crafting, all the required components need to be in the inventory and will be used up in the crafting process. A crafted item will appear in the inventory, crafted camp upgrades will be placed in the homecamp (and can only be crafted there) while crafted clothing will be put on the character immediately.
Outdated crafting menu. Blueprints in the knowledge docket on the left and the required components on the right.
