I just got it the other day (because I saw it here) and it's pretty interesting
I've got a 27 Dark Magician on Tortus.
Quote: "For any mage type character mana sucks. When your in a dungeon party people should use mana scrolls on you whenever they can."
I don't really have any problems with mana. I've got rank one fire arrow and thunder bolt, and I just spam fire/thunder/fire/thunder, sometimes with a soul chip and they go down pretty easy and I hardly use any mana.
If I get low on health, Nightmare+Soul Chip+Whatever-that-life-draining-spell-is, and I think I can heal from corpses too...
