[Double (Elder) Dragon achievement not advancing]

Could that be  because they got all the achievements already and don't need to do all that work?  All they have to do is stand there and wait , get a couple of hits in and stand up there and watch the rest...probably just there for the drops after the event, they are not there to do the heavy battle they are there to get the achievement and or the drop.  Why do all the work when every one else is doing it for them.. 🙂

[Double (Elder) Dragon achievement not advancing]

ok i know this is  an old one but i see some recent posts and i think i figured it out.   You have to have a t least one hit on both Champions for each round and you have to hit both dragons at least once with the special weapon and then you have to use the channeling  by the prism when she calls you back and let it complete.  I recommend if you have a skyscale to trigger your skyscale as soon as you hit the dragon with that special weapon and double time it to each point where you need to get to the other dragon, remember at least once for each dragon and you have to get your hits in on both champions for each round. If you are an expert with the beetle go for it if you have it. But the Skyscale works while you are still in the air.
