What Professions are Best for a Mage?

Tailoring
Alchemy
Enchanting
Jewelcrafting

The above professions are those which are the most useful for Mages to actually use to provide themselves with gear and items. If you are looking to make lots of money through a profession you might want to alter your choices a bit but in terms of Mage usability the above professions are the ones to choose. By training Tailoring Mages are able to create wearable gear for themselves. With Alchemy they can create powerful potions that can restore mana and health, increase damage, among other things. Enchanting give Mages the ability to give themselves powerful enchants and Jewelcrafting of course allows them to cut their own gems and make their own jewelry.
