All of his skins are meh, they provide an amazing character model and concepts, but don't have the particles to back it up!
Karthus needs a staple skin other than black robes w/cool splash art (Reaper). A "go to" skin that changes his abilities, a fresh new model and tinted ability colors.
Some ideas could be......
_ Headless Karthus - Abilities tinted orange/dark red. _
_Frosted Karthus (Frost fire Karthus?) - A twist on current skin meta, but has potential, frosted spiky and dull blues with the model having shards and frost.
Blood Moon Karthus - Follow up on the other color schemes of the other blood moon skins. (imagine kathus with a mask)_
These are just a few on-the-fly ideas, to get the creativity flowin.
What are your thoughts? Do you agree?
*EDIT* omg imagine "snow storm" karthus, hes positioned like hes about to attack with his basic auto attack, hes wearing tattered cloths and a grey/white robe, he has a torn-up rag around his mouth with a blizzard going on around him.
