I've done everything I can, and I still cannot beat the secret boss of Illusion of Gaia (he's like the firstboss of Soulblazer, only hard). I've gotten to him with the max amount of herbs/leveling/HP possible, and I still cannot beat him... Although, that just makes me assume that (like most bosses in action games) there's some sort of secret tactic that makes him exploitably easy... Damn hidden tactics!
