I think there is also a stigma merchant in the cities. Somewhere near the Stigma Masters. I know I saw one in Beta in Sanctum. Maybe that NPC was just there for the Beta because I have not actually found one in Panda.
I was wrong about the merchant. The merchant that I recall, in Sanctum, just sells the lvl 20 stones that come from the quest in case you somehow deleted or sold yours.
Hey Fem. I saw your post on my website. I thought all that info was on there. Me and a few others wanted to keep some of the ppl in ffxi together. But I am on Israphel. Im sorry :(
