I've got 670 gems now, thanks to a long time of saving them up. I'm at level 30, and would be able to expand to the glimmergate now. But I haven't got any dragon. I still need the diamond and the ember. (I'm at aproximately 10 desert sand adventures and 50 deep mine collections for now.)
I don't know if I should buy the dragon and go on with the storyline (since it will take more time to get all those dragon scales anyway) or if I should buy the barracks first.Maybe that would help to make more desert sand adventures (even if its difficult to make so many sweet feasts) and would also be helpfull for the time limited quests.

What would you do?
Oh and I've already bought two wizard schools.

Thanks for your help.
