Ok if u are a ARCHER pm me and i will teach u the best trick ever made
WARRIORS:since warriors are strong.You should hit and run but try to use frost hammer and flame hammer the most.So it will go like hit and run hit and run.^_^
MAGICIANS:You will be very weak.So u are gonna need to have at least a warrior with u so u wont die.so when at boss, u will stand a little far from warrior so u wont get hit.Heal yourself instead of using pot.So u can save money.
THEIFS:well just jump and press x on the boss and use Z as a extra attack, try not to get hit.
