cost of ruby will be allways random   - depends of ad network income and how much rubies are people converting
hopefuly i can purchase all rubies at least once per week, i will announce every news in dashboard - on the top -> admin messages

sometimes the price of rubies can be much higher (big ad network payment or so)

Made a small but useful update -  every winner of battle gets +2 skillpoints, when is draw = +1 +1 skillpoints for both.

happy upgrading
