It would be neat to see your veins glow different colors depending on the spells that are being cast for example: illusion spells wich usually cause green stuff to fly out of your hands would cause the veins in your wrists near the hand to glow a feint green, but only when that spell is cast. The amount of glow for each could depend on your skill in that school of magic 70 pts into restoration would give you a halo of light from your hand. It worked well in bioshock, and they are adapting some of the combat from that game why not add that aswell, it seems completly viable and would be a nifty thing to see. Also a toggle on/off for it in the options menu. Anyone else agree?
Well I don't think all spell need color veins some of them maybe but not all, for second thats will become useless FX if character will wear gloves.
May glowing aura effect around hands is better? It will glow over equipment and there can be different FX
For example like Daggerfall have
