In a nutshell, your hero character will have the ability to assign crafting, gathering, and even mission skills to various NPC crew members. While you're out saving the galaxy, chasing attractive Twi'leks, or whatever it is that heroes do these days, your faithful companions will be doing all the grunt work involved in keeping you competitive when it comes to crafting.
Gathering skills include bioanalysis, scavenging, and slicing, while crafting skills break down into armormech, artifice, and biochem categories. Last but not least, mission skills feature diplomacy and treasure hunting. That's not all either, as the web page features a few tantalizing question marks indicating further skill reveals in the future. We'll tell our astromechs and slicers to keep a sharp lookout, and in the meantime, you can view the crew skills video after the cut.
