Most important tip for a mage: Don't get hit. It's not that hard. If you are casting a master spell in front of a few enemies, you are doing it wrong. Mages=attack from distance. It's not rocket science. My dunmer mage is level 35, has 130 Hp, 500 magicka and I can take down anything easily. If I get hit though... My equipment includes a vampire robe with 10% fortify destruction and magicka regen, Gauldur amulet, ring of eminent magicka, vampire boots with 24% frost resistance and Zahkriisos' mask. Sometimes I use a staff. Don't need to level up enchanting. Learn how to play a mage.
