The quest "Aces High!" By Corastrazza (Coldarra), in its initial state ( the yellow quest that will lead to the daily) can not be completed by any normal means. Unlike the fully working dragons inside the occulus, the dragon provided by Corastrazza has only one working command, being the last one (Fly?). Once pushed that command remains "pressed in" . As no attacks will light up regardless of range, i can not slay the blue drakes. I could think of something like going up there kiting them to a nearby platform and elite-ing my way to victory but thats not the way this low-level daily was meant to be played.
