I’m glad this has finally gone live because it explains quite a bit about the way that Sona plays. As it turns out, every cast produces a persistent aura that remains in place until 3 seconds after the next aura is cast. It’s a playstyle that closely mimics Udyr and will provide solid support in the right hands. As Phreak mentions in the video, though, Sona is very frail, so it’s likely we’ll see a LOT of Sona players that can’t manage to keep themselves alive.
