League of Legends Sejuani Patch Preview Trailer

Gameplay changes for existing champions, items, and other gameplay, as opposed to information about Sejuani herself
Riot Games has released a new video for League of Legends, an online multiplayer session-based game in which rival teams compete against one another for victory on highly stylized battlefields and landscapes. Hailing from the Freljord, Sejuani combines raw, physical might with the chilling ice of her homeland. After slowing enemies with her Frost passive on auto-attacks, she can activate her Permafrost ability to drastically increase the slow and inflict damage. This allows her to continuously disrupt enemy movements and create a threatening presence - a necessity of any primary tank.
