It's the top milestone in the realm event. If you got all 3 yolks, then you should've gotten that milestone. It would be a crystal in your inventory
Darn I guess I missed that for some reason. Thanks!
You needed to have done the objectives by winning BG matches with VtD to get the milestones…I think…it was such a chatic event that I've lost track!! :D
That was something separate. The BG objectives were aimed towards the 6* relic.
