I need some help, I am having trouble with magic in Oblivion. Just a quick question but can you increase your magic count and how (if you can)? How don you upgrade and get better spells? I have been very confused with it and the menu's are somewhat difficult to navigate. If anyone can just outline the magic basics or more even the more advanced stuff that would be help full. Thank You!
