Im going to back Bolivar are on the usefullness of the scholer. I mastered one (very early too... they level pretty quick) With the book upgrades he could hit for just a little under my knight... and when his elemental books attack enemies with a weakness to them he surpasses my knight. Double the effect of Spells cast by items gives him stronger magic than my black mage. Clearly under-rated seeing as its been mentioned in this thread just once
