Whenever Janna gets buffed by someone else (e.g. Jarven E, Nunu W) her passive on another ally causes Aery to proc. I guess this happens to every champ which that kind of passives, but i cant think of another than Janna.
One thing is wrong here. Your wording or understanding. The video shows Twitch getting movement speed buffed by Janna's passive. ANY kinds of buffs from what I've seen can proc aery.
Yeah just got this one in a game. Watched replay multiple times trying to figure out what it was, ended up googling it in confusion which led me here. Same situation, Jarven standard and Janna passive gave Jinx an aerie proc.
