Morrowind and Oblivion had these too you know, it's called fire damage. The only difference now is that they've added a cool new effect.
Not to burst anyone's bubble but this is all concept art. A lot of stuff gets drawn in concept art but not all of it is included in the game. Just google the female daedric armor concept art for OB, you'll see what I mean.
im not sure we should take all the consept art so seriously. i dont know much about making games, but i would guess alot of that art is never used
shhhhh don't ruin the moment but I guess you're all most likely right
