@perniciousintent The only problem I see so far is that intelligence is to broad a term for an attribute. Need to go a 'layer' more specific. Think 'logical' or 'creative'. Also concentration is fine but remember it won't be much use to you unless you are going for those impressive ritual spells like firestorm or intend to create a unique ritual spell for her. The advantage is also fine but remember that it's hard to quantify things like mana regeneration in a story based game. You may want to make it something a bit more dramatic or utility-based, otherwise it might fail to really effect the story.
