Spell making and enchanting was one of my favorite things to do in the previous games. They removed the enchanting skill in oblivion, but it's coming back in Skyrim. You win some, you lose some.
But all I needed for combat was my 1 spell that stacked weakness to magic, 3 elements, absorbed health and did all 3 schools of damage. And then I spammed that and killed everything that was not immune to magic. I can see why they removed the altar because it was quite overpowered.
