but how do you come across the custom shell... I am so confused when it comes to this system some times...

Hello I know this is a really newbish question but I have a lvl 18 sith warrior and I would really like to know alittle more about this topic as a whole and the whole Modification ability seeing as how i cant find anyother topics in holonet or on the game. So if anyone has the time to spend to write me back please feel free.
