Opal shoulder style pages obtained from the undaunted pledge NPCS

They are on offer for 50 keys, but I am unable to actually buy some of them. It says something along the lines that I need the knowledge of the style first before being able to purchase? What am I missing here? That is kind of why I want to buy them.

I thought they were on offer for 50 keys as another way of buying them instead of tickets? Or does it mean I must have looted that monster set style for the shoulder at least once? I really don't get it.

There is no such restriction at the Impresario.

you need the normal motif before you can learn the opal version, these are dropping at a low rate and sometimes drop with the helm or you can buy them from guild stores but are very expensive

Ah of course okay thank you. I don't normally collect the monster set styles so I was not sure.

I quite like the look of the opal color scheme though so I'm actually putting in some effort to get my hands on them. Silly me for thinking there would be no hoops to jump through first though :-p
