Thanks for the input, so how do i get enough magic resistance without using alchemy or enchanting? I play as a Nord so he should have 50% resistance to frost.
indeed if i found magical items i can use them i just dont create them my self
There is a Blocking Perk that reduces elemental damage by 30% if you're gonna use a shield, and there is plenty of loot enchanted with magic resistance. Doing the Companions quest you could find the Shield of Ysgramor early on, an it has a decent resistance to magic. Later on you will find even more powerful pre-enchanted gear, so I wouldn't worry.
As for Dragons, you have your shouts and later on the MQ you will learn a shout that will help even more against dragons.
