Since you're a hunter, you won't have access to rods, wands and TCSMs right off the bat. You need to go to the job counter and pick extend type. In that menu you have to upgrade the rank of said weapon(s) to be able to use techs with, and you will need extend points. You can get more extend points by increasing your job level.
Then you need to buy a rod/wand/TCSM. The 1* variations are always available in the shop in the demo.
I was hesitant to get into PSP2 after hearing how horrible PSU was, but once I found out this one was going to have free online play, I knew I was going to have to go ahead and give this one a chance. I haven't been disappointed yet.
