# Blueprints

Blueprints can be used to craft advanced items. <img src="/files/h9govvbQwXDwxXMpLdVJ" alt="" data-size="line">

Blueprints are important for the Catddle Universes, as they represent advanced technology and higher productivity. Passing blueprints across chains is not allowed, as it will cause issues between multiverses. Blueprints can also be worn out after being used many times,

### Original Blueprint

The first blueprint of a specific item is called the **original blueprint**. It is created by [inventing](/activities/research.md#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.&#x20;

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.
