Unlock a1s

Sorry if I'm in the wrong area for this but I'm trying to unlock a1s. I've finished all of the msqs, all of Alex normal, and ultimas ballad. Do I need to do the second coil? What am I missing? I googled it and it just tells me to see the minstrel, thanks in advance!

Just need to turn in the associated quest with Alexander which you complete after beating A4 for the first time, then talk the the minstrel in revenant's toll, that should be all you need.

Thanks, something that easy was the problem. My enigma quest wasn't turned in..... Thanks again!
