I have the same build as you, except I dropped magic resist for bushido. It's a great skill because it takes no points or reagents like other skills, and every book you buy already comes with all 6 spells. Not to mention, when you have evasion and lightning strike (bushido spells) along with the damage from the chivalry spells, you become one hell of a warrior. I can solo ancient wyrms no problem with this build so long as i keep evasion cast. The only downside of it all, is you'll need more mana, and mana regeneration to keep up with all the spells you'll be casting.
