I love AC4 and I play it on PC, but I have a problem; I can't seem to find a way to get the Black Skull Sails. I know that they are unavailable on AC Initiates and I cant enter the site anyway to find out because I bought Unity off g2a and I don't have the code for Initiates. Regardless, I was wondering if is there any other way to get them or does someone has a uplay key for them and doesn't need it or to be able to buy them from somewhere anything goes.

Thanks in advance.
