but i dont really care how it will be made, i just hope there is a good way for keybinding, so that you dont have to look up your spell etc, but that you can cast them fast. else you are attacked by a warrior that runs towards you-> you go look in your book/inventory or whatever for your spell. you selec..... to late, your head has been cut off. no fun in that, now is there? (well, maybe fun for warriors:P but not for my mage)
