as an aside, I checked and my bad, I did indeed do 75%+ of the quests

Mags, your build sounds somewhat similar to my own, I spent most of the time with Shimmering shield, combat magic, spell shield, arcane shield, stone armour and flame weapons active myself. still if you choose the right gear/armour you'll find you can cast plenty (I generally get a mass heal a couple of the storm spells and a fireball out of my mana before it expires and I need a potion)
