aspir

i'm wondering the decideing factor's of aspir. knowing 1 and the most important being dark magic skill, but dose Magic attack bonus as well as INT effect how much MP is drained?

Well my blm is finally high enough to use this spell but....I cannot unlock the quest from Fuepepe.I did the quest about waking up that kid in school and also maxed out the fame.I even did the painting/inner hiroruto quest.Anyone know what i need to do before i can flag this quest?.I really hate...

i got this off a yag in Giddus what is it used for.
