The next champion of League of Legends is Vex. League of Legendshas tons of adorable champions known as Yordles. The next champion, Gloomist Vex, is reversing this trend. Vex looks like a powerful mage because he has a large shadow buddy that helps him control the battlefield and can adjust his abilities based on range. Riot hasn't definitively revealed Vex's abilities yet, but in the video we see Vex using his shadow to move around the map faster as the opposing team tries to slay the dragon.
We knew Vex was on the way thanks to the Sentinels of Light lore event. Vex is known to help the Ruined King Viego and wants to hang out with Amumu, the sad mummy who has no friends. That's why the next champion of League of Legends isn't such a bad guy.
