Retainer Gunbreaker

You need to buy a jobbook for the job you want at the "retainer-shop" (were you can hire a retainer) in one of the major cities. They are usually near the marked boards. One book costs 40 ventures.

Thanks for the answer, but I did get the book. However it will only allow me to choose "Ninja" as a job. I did that, but then I cant level him higher than lvl 50, since I only have Ninja at lvl 50. I continued with Samurai and then Gunbreaker to 80.

Also with the "boost Retainer to 70" book from the mog station store I can only boost my retainer to 50. It even warns me. Same with the class "rogue", the only one that is available for me to choose.
