I am an element in myself. Kinda like an elemental. Of me.
As the Midas Magic mod for Oblivion has shown me, the best combat attacks involve many different attack elements. For instance, I usually knock the enemy over or trap them, then use an AOE spell right next to them, then finish them off with a destructive spell that lasts a few seconds. But there are other elements that are more useful for getting around and arguably more fun.
However, if I was some sort of magic character, I always imagined that I would have an attack called Cheese Fire, which would spew molten cheese all over the enemy. And if I was feeling really nasty, I would turn it to Ice, leaving them scorched and frozen inside a shell of cheese. But I would only use that on my worst enemies of course.
