I am new to Final Fantasy that is why I didn't know that leveling was important. I was with Vaan at level 8 most of the game. It was hard winning and I had to repeat about 5 or 6 times till I won.
Now however nothing seemes to work. I am at the part where I get Princes Ash out of the cell. I did that but now I have to go back and fight with the Judge and no mater what I did or spells used I cant win

. I have read some where that I have to level up. now I am 12. how high does my level have to be before I can easily defeat him and what kinds of spells and weapons that can help me? are there any kinds of spells I can get at this point of the game?
