Daru and gold your biggest gain for both is World Boss (WB) you can do this twice a day, try and do it makes a huge difference. NEVER bother buying gold or daru complete waste of balens ( = money).
Balens you get 300 a month free, and on completion of a campaign map. It is possible to do this game without spending real life cash, but to be honest its very,very difficult. The quit rate is bad. Also if the server your in doesnt meet their standards of revenue they will merge with another low revenue server.
Stamina comes from cultivation (+60 a day for 2 hrs logged in doing nothing) You get +100 every day, and you get stamina potions drop rarely, and from promotions occasionally.
Their are skills and abilities that can directly hit an opponent rather than random. As you play the game you'll discover how.
As for CHE ATS you have not a hope in he ll of any such thing, if you can find a cheat by just browsing the web then i would savvy a wild guess that a billion dollar a year industry which these games are could find it as well
