This is a bit sketchy, but I really like this design, so I'm posting it in my main gallery.
This is a concept for Rito wearing his coronium as an armor, and a rather... exposing one at that. He can only produce so much coronium at once, so he can only cover so much of his body. He can technically change the shape of the armor on the fly, but keeping it in a set form helps him focus on combat instead.
So, yeah. Silly fantasy magic armor.
