Hi all,
I'm playing Sejuani as a slow tank. I'm making this guide because I just wanted to try making a guide and let the other Sejuani guides see that She's a good melee fighter and a very good support for the team.

Use Northern winds as your most damage output. Level it so fast as possible because it's a great farm and a good attack move. You don't even have to attack your enemy just use Northern wind and follow him/her so they won't escape. In a solo battle use a combination of Northern wind and Perma frost to deal massive slow and kill your enemy. In a team fight the same thing, jump in with Artic AssaultUse Northern wind and Perma frost to deal massive damage an dget the kills!

Use Glacial prison to help other teammembers of getting a kill and you an assist or to freeze 2 or 3 enemies when they are passing.

Flash is to get away from losing teamfights or low health situations. Ok you can also use Artic Assault but sometimes it's still on cooldown and you are death.
Ignite to secure kills and just for a damage output.
