I've played through the game a couple of times (well, large parts of the game including the MQ; I'm playing again to try to get things I missed before). One thing I've never quite figured out - I know there is a cap on what your armor rating can be (I think it's like 75% or 85%, something like that). If you already have high armor, but you cast a shield spell, will that save your armor from taking the full beating, to preserve your armor condition longer? Seems like I recall that certain enemies can bash down your armor condition pretty quickly.
I'm playing a Spellsword, and considering not taking smithing as a minor skill this time, and trying to figure out strategies to deal with that. I figure I'll try to carry a spare set of armor and spare sword, but weight limitations being what they are sometimes, I'm not sure I'll be able to do that, at least, not until I've got good enchantments and potions of +Strength, +Feather, etc.
