Since the game has a new battle-system, you should go talk to the old man in Arni village (home world), if it's that.

Basicly it's just that you have 3 ways to execute your attacks: normal, strong, very strong. Each of them has its rate to suceed: normal will surely succeed, strong maybe too and very strong will probably miss. But each time you hit your opponent, the chance of getting it hit will be greater; for example the 70% for your strong attack will increase to about 89%. got that?

At the beginning of a fight you'll have a stamina worth about 7 points. Each time you perfom an attack, your stamina will decrease. If your out of stamina, you won't be able to perform another attack. So we got that too, right?

Last thing would be the usage of the elements. Each time you suceed to hit your enemy, you get an element-point. Some elements need 2 points, other 3, oder 4 and so on.. So, if you're on element lvl 3, your could perform a lvl 3 casting...

That's the basic idea of the battle-system. Hope you got that.

But.. why the hell did I... oh, yes.. I'm bored.
