Character builds on this game rely heavily upon equipment and , to a smaller extent, treasures. It looks like you could use a bit more, meaning better, equipment. Your stay bonuses lead me to believe that you don't have many treasure yet either. Fight in the arena daily to gain keys or save souls to just buy treasures. This isn't a complex game, all you really need is patience. If you aren't patient then you can spend as much as you like and get it all right away. 1000$ to have a cool digital game for your phone isn't too much, right? Good luck.
