Either get two sets (being Unique) you would need one of them in your retainer, and switch around as you switch classes (too much effort if you change constantly ) or do as I did back then. I crafted 200 of each glamour prism I needed for my set. Glamouring different items as I switched classes. Both ways get tiring after a while and SE says data problem bla bla stuff and we most likely won't get it o.o
