is there anything i need to know that will help to defeat the second boss because i cant defeat the guy because he keeps defeating me
You can drink potions BEFORE going into a battle to buff them beyond your current level. I got stuck at the same point because I didn't know that. I was only using them mid-battle to replenish. If your skill is at 7, I think the medium potions can be drank twice to buff it to 8.4. Do that and use super effective skills and you should be able to defeat him.
