Elementalist Nocturne

I really think Nocturne would fit perfectly with the "elementalist" skin-line. IT would have to be an ultimate skin, and do the same thing as lux's skin.

His q would change textures/color with the elements picked. His w would be no different than ELE lux's shield animation, His e would stain his target different colors while they're being leashed The paranoia caused by his ult would be colored based on the elements chosen.

As for base Nocturne, theres 2 options:

if Its a cheap/fast route to make the skin, keep it basic. make his color change with the elements, and accentuate the "wings/blades"

If its a big project.. It'd be awesome to see different armor variations depending on the elements he picks. Earth could look more heavily armored, while fire could look more spikey. Air would be some cloth type of wraps that surround his shape.

I would also like to mention this idea was originally for ZAC, because I think he would fit in it in a similar way.
