So I found a Spell Tome book: "Telekinesis", in a dungeon and I think it is a Adept or Expert level spell and it takes around 189 Magicka per second. I can only use that spell for like 7/10's of a second with my Magicka completely full on the account with the most Magicka (around 220 or something).
How do I get it so that I can use Telekenesis for at least 15 seconds? Although I have thought of getting the Adept or Expert perk for Alteration that makes it cost half as much Magicka, I think it would still not take long at all to completely run out of Magicka. Also, I have thought of finding an Alteration trainer, but I can not seem to find one.
