User blog:The Heir of Isildur/Best Mage Gear in Oblivion?

I have been playing Oblivion and I created more of a pure mage and I have been really enjoying the game once more, but as I reached level 20 I have had trouble finding gear that can keep up with most enemies. If you guys can help out and comment what good robes, enchantments, etc. are good for a character my level. Thanks!

P.S. My character is a Breton who was born under the atronach stone and I specializes in most schools of magic plus blade and light armour.
