So if I start PowerPlay to get the special weapons'n'stuff, how exactly does it work?
Let's say, I want the Hammer and Prismatic Shield. I have to one faction first, then as soon as I got the special item to the other.
However, am I still able to buy for example the Hammer after leaving the faction? Or do I have to buy several of them for each class and store them somewhere to be able to use them?

Hope it's clear what I mean, otherwise let me know.
