Yes, I have noted this, and you have made it o-so clear for me, thank you, I didn't realise what I would do if I was fresh out of magicka, anyway, I will easily get the Divine and Almsivi Interventions amulets >when I do one of the Mages Guild Quests<If you want to be a mage character entirely reliant on spells... I would go for the Altmer. Restoring magicka with the Atronach, as Moltovir noted is no problem. And, not far into the game you can find, buy, make amulets of Divine Intervention, Mark/Recall, which means you don't have to use magicka to restore your supply (also handy if you are totally out of magicka and have no potions).
Yes, and I will absorb even more magic once I collect the >Necromancers Amulet< and I will also be able to reflect some of it, and resist the fire damage, with the >Robe of Drake's Pride< and with the the >Mentor's Ring< I will be able to resist some of the Magicka, all which you have already mentionedAs far as being vulnerable to magicka, this can be quite easily overcome if you decide to make things a little easier. For one, the Atronach, will go a long way to protecting you.
Thank you too for the intel dragonwench!!!
