Your text seems to end in the middle of a sentence?
Maybe it should ... not do that?
Anyways, from the point when you have the Mana Shield Skill HP are no longer a concern. I noticed the Familiar then being pretty damn good. Just because he could cast like my Mage Sovereign. (But that is just that one Quest that you need so its not really helping I guess)
There is also the Guardian Statue with the Sovereign Bond (aka 'can cast all spells your sovereign can') which only spawns during a city defense.
Maybe that thing would be better off being the familiar?
