When AP Sona Slaps You With Her Lichbane

I remember that game. xD But is Sona that evil?

: "I'm gonna remix yo face!"

Sona was never 'good' to begin with. In the old lore, she's basically a musician version of Draven. She played music, discovered she could kill people with it, then joined the league just because killing people would grant her a larger audience than performing concerts.
