Im a mage type/sword swinger, and I want to do some powerful spells but they all require like hundreds of magicka. I have about 100 magicka and im already level 10, will i ever have enough to do powerful spells, and how?

Pactise your Intelligence.
That's the onlt natural way to increase magicka.
Sure,there are items that will boost your magicka,but i wouldn'n relly on them that much.
You can practise your intelignece by casting Mysticism and Conjuration spells,and you can mix potions with Alchemy......

Do you have time?I don't know.You probably do,because you are level 10 and max level is level 40-50(As far as i know)

Oh yeah,with high restoration you can Fortify your magicka too.......And you can do the same with potions....

I hope this answers you.

If its 40-50 its impossible to max your luck.

For the most powerful spells you not only have to have lots of magicka but high levels of the governing school. For instance, for a Summon Daedra Spider you will need 75 conjuration.

Best to concentrate what you can do for now, since the game levels opponents with you.

I didnt know that.So if youre high level, the boss is high level? Sounds cheap that training wont help you kill things.
