Help with Fantastic Knights, please!

Hello,

I am playing as Wenrick and am at level 32. I am at the battle against Adamos and get killed very quickly. Sometimes I can battle him for a little while using lots of heal pots but it usually ends very quickly. What am I doing wrong? Is this a bug?

I have tried over a hundred times but no success against him. I am reayd to quit the game altogether.

Help! Suggestions? Spoilers are ok at this,point.

Thank you!
