As Bard you will be fast as hell & have some other Buffs like Mobs dont touch you. But the other skills arent good, cause they are magic skills and u are str.
And all other Buffs doesnt works if you change your weapon.
As Cleric you can be a good Helper char too with ress & Buffs, and you can make yourself for 45sec untouchable.
But you need to buy drug of winds to run.
YOu have too farm like 200k SPs i think.
