What is the point of hitting R2 what does that magic do? I hear about throwing fireballs and making potions. How to you do this? Does it have to do with what type of guy you create? I'm a first time playing and I'm really into the game. Just know there is stuff im missing out on.

If you mean skyrimm I haven't got it yet but on the older oblivion you brought them from mages guild hope it helps
