Blueprints can be used to craft advanced items.

Original Blueprint

The first blueprint of a specific item is called the original blueprint. It is created by inventing.
The original blueprint can speed up and lower the cost of the corresponding crafting. The original version of the blueprint will have more durability.
The corresponding technology will be lost if all blueprints of a specific item are consumed. A new inventing process will be required again to unlock this technology.
