I came to know that those who completed the summer nyxmare rescue hard path got the artifact but not the raven dragon i.e, the heroic boss at the end
This means only one thing.....
Raven escaped and WE ARE GOING TO HAVE ANOTHER RESCUE!!! Of course Deus is freed from the spell.
I'm fine with the rescue if we need LoD dragons and of course huge improvements in the rescue.
But if we need new dragons,.... Well I can say only 2 words:- we're dead.
