Xerath skin concept- Preritual Xerath
I am no artist but I know that this would be a killer skin to the lore lovers of league and it would offer plenty of opportunity for hidden taunts and the like. In Xerath's lore it is stated that he was once human and studied in arcane magic to unlock unlimited power and the secrets of the universe. The current Xerath appearance is due to a ritual he went through the discard his human body. Therefor a human Xerath would be an interesting concept.
With a human Xerath the arcane power could change on a couple levels, depending on what stage before the ritual the skin is set to. Right before the ritual Xerath had gained so much power that it was destroying his body, which could lead to some interesting design concepts such as singed skin, a sickly appearance, and possibly red abilities to show the arcane power corrupting Xerath. Before that it seems that Xerath had a hold on the power which could give him a healthy, strong appearance with yellow abilities to resemble something like the Arc skins.
Both versions of the human skin could lead to various responses to other champions in League. Xerath already has previous history with Syndra, however the new skin could lead to some interesting taunts depending on the skins, such as Syndra saying something like "Your powers make you weak, when I am strong" in response to a sickly human Xerath. The healthy Xerath could respond a couple different ways to Syndra with something along the lines of "I will shine through your darkness", or (if Syndra is using her Justicar skin) "You shine bright but I shine brighter"
Of course there are various other champions that Xerath could react with, like Varus with his Arc skin, Ryze, Nasus, and Zylean (father time, unlimited power).
If anyone has a similar idea and can actually draw I think this would be a great addition to league and could give Xerath a little more time in the spotlight again.
