This game is amazing with so many things to do in the beginning. However, eventually you run out of dragon stones. Dragon stones are used for summons, which are the things that allow you to get better characters. I had to stop playing on my first account because the only method to get dragon stones was to wait for the daily reset and login bonus. And with release of plenty of new units, Stones are becoming an issue. There has to be more methods to obtain stones.
