What to stock up on?

cool, thanks. And ive noticed that people are finding out about this. Went to the APQ area the other day and people have started asking why I need them and a few have been asking for black crystals. One was even about to trade me but he was like "oh wait, i forgot. Need to save these for the maker skill"

I have like 300 or so dimonds so i should be able to make a little bit of money
