I'm playing the PSP remake and there is something I need to know. I heard that even though Ultima is called a white magic spell in the manual, its power actually relies on the caster's intelligence. I want to know if this is true, 'cause I'm really close to obtaining Ultima (I'm at the Cave of Mysidia) and I need to decide who should learn it - Firion (my white magic user) or Maria (my black magic user). Help.
