Basically, it uses ...
... your character's spell points to drain his/her opponent's hit points, and transfers 30% of the points drained to your character. It requires the caster to have GM in Dark Magic, Expert in Light Magic, and Normal in Elemental Magic.
I'm reposting my question here, because the other thread got too bulky
It looks like you were saying the character would have to have both GM Dark Magic and Expert Light Magic AT THE SAME TIME. I didn't think that was even possible. If so, which class would that be?
