If DJ Sona is the Ultimate Skin...
What were those hints we were given?
Hint 1: Champion has a spell which has A as its 4th letter. Hint 2: Random words and letters hinted by a Rioter - "Six, S, Hide, Assassin, J". Hint 3: A hint posted by a Rioter for "the best clue" he could give us "541daw6s5d41a6s5d". Hint 4: A, E, I, O or U (One of the letters in Champion name that is receiving the ultimate skin). Hint 5: Champion with few skins will receive the ultimate skin.
It's rather confusing.
