SillyGuys easy super lvl method is awesome but u can get a litle weak, so dont put all in attack an put some in armor (but just a litle) and its good to have heal (just in case) but theres no need to get strong heal, and to save mp (wich will be needed later on) u shouldse if you can finish with justa a charged blow.
I agree that RedFireMage is overpowered but if u just gat enought mane theyre not a problem (my build was a chaosfiremage (aim to get high attack and mana burn first) then i just manaburned them down and finished them in 2 shots)
