Artisans are a specialization of the Sentinel Career.
Some Force users have an innate skill with tools and machines. These skilled artificers can use their skill with the Force to enhance their abilities, and even intuitively understand a machine’s form and function. Artisans acquire Astrogation, Computers, Knowledge (Education), and Mechanics as additional career skills. In order to fully integrate their Force abilities with the devices they manipulate, they must first have a solid understanding of how those tools work.
The Artisan can be found in the Force and Destiny Core Rulebook.
