I never used Mistery seals but im pretty sure that it is to use on reeincarnations to unlock world mysteries previously unlocked by progenitor.
Someone correct me if im wrong
You need 50 for tep ruby. You need 60 for greatness from what I've heard, and I believe this topic has been posted already as well.
As u can see on the link, some one says 30 for each quest and 60 for greatness. Other one says 65 for greatness. I asked in zone chat ppl said 10 for sealed powers!
Quoted
"Mages" removed from the curio shops. Instead, the players available, "Shards of Mystery Print". For each Secrets of the World requires a certain amount of debris. All "Seal Secrets", remaining the characters will be used and will be converted into 10 "Shards Print Secrets".
