Sorry Thandal :( *adopts a hideous expression of malady and woe* Anyway, back on topic. An alternative? Yeah, I could see that... instead of amping yourself on blood, it'd be much larger amounts of mana through, perhaps, lyrium? All of your spells can be roughly made, though I am not supersure about Persistent Magic. I don't think you can be weak to a certain, single spell, but rather an elemental weakness (the resistances are all divided into elements: cold, electric, fire, nature, spirit) or an overall spell weakness - that would, however, not work in unison with the immunities against Neutralization (anyone got the resistance type and element for that?) and Dispel magic (spirit school).
