I am wondering if anyone has concrete information on these. I have searched the web but not found definitive information about these. I have read that each boss you kill will yield a sigil and a couple that just say that they can drop. I ran Guardians of Mogu'shan raid last night and killed the first three bosses but only got one sigil. Should I have gotten one from each boss or is it a random chance? Thanks in advance.
I only got one from the first boss as well. I believe that the first boss gives everyone one, but maybe then the other bosses will drop 1 that goes to a random player or not drop at all. Maybe later bosses in the raid drop one as well. I don't know for sure... But I feel like the next raid will contain the sigil of wisdom and it gonna be that u have to raid 5 weeks in a row (LFR and 10/25 man) to get all 10.
