How To Play Sejuani In League Of Legends

Tanks are never out of style thanks to their durability and great crowd control. Sejuani belongs to this class and let me tell ya, she has no trouble fitting right in no matter the meta. Here’s everything you need to know to get you started playing the Fury of the North.


Sejuani is mostly played as a Jungler but as the meta shifts, finds herself somewhat viable in the Top and Mid Lane. For this guide though, we’ll mostly focus on her being in the Jungle playing as a Tank. So the biggest reason why Sejuani works and why she’s a great pick is because of her lockdown potential. She can easily lock down high priority targets in the event of a team fight. Her Jungle clears are also pretty great so you don’t have to worry about being at a disadvantage when the enemy tries to counter jungle you. All in all, Sejuani is a very solid champion and can fit a lot of team compositions that are looking for a durable front liner that can soak damage as well as peel for their teammates.


Sejuani’s kit revolves around dealing crowd control in any way shape or form. This makes her absurdly good at ganking and setting up kills.

Passive – Fury of the North

Frost Armor: After not taking damage from champions or monsters, Sejuani becomes immune to slows and gains 10 (+50% bonus Armor) Armor and 10 (+50% bonus Magic Resist) Magic Resist. Frost Armor persists for 3 seconds after taking damage from champions or monsters.

Icebreaker: Enemies stunned by Sejuani are frozen, causing Sejuani’s first attack or spell against them to deal [+10% target’s max] as magic damage (300 vs Monsters).

There are two parts to Sejuani’s Passive. The first part, Frost Armor, is the most important as it makes her ganks that much more powerful. Being immune to slow and getting bonus resistances makes her harder to stop once she gets going to her target. The next part, Icebreaker, helps her deal more damage to targets she stunned. It’s great for clearing waves and just dealing damage to other champions.

Q – Arctic Assault

Sejuani charges, dealing magic damage to enemies and knocking them up for 0.5 seconds. The charge ends after hitting an enemy champion.

This is Sejuani’s main mobility tool. This can go through thin walls and terrain so you can use it to make a quick escape or to catch enemies off guard. It’s a great way to engage during a gank and the crowd control from it can be enough to set up all your other abilities.

W – Winter’s Wrath

Sejuani swings her flail, dealing physical damage and applying Frost to enemies hit and knocking minions and monsters back. She then lashes out with her flail, dealing physical damage, applying Frost and slowing enemies hit by 75% for 0.25 seconds.

This is Sejuani’s main ability when clearing jungle camps. There are two parts of this ability and both parts apply frost which you can proc to stun your targets. The first part is where the crowd control comes from while the second part deals damage.

E – Permafrost

Passive: Nearby melee allied champions’ basic attacks apply Frost to enemy champions and large monsters.

Active: Target enemy/s with 4 stacks of Frost take magic damage and are stunned for 1 second. An enemy that has been stunned by Sejuani cannot gain Frost every 8 seconds.

Permafrost is the core ability where you’ll base most of, if not all, Sejuani’s combos. It’s because of this ability why you can apply Frost to enemy targets. The active part of this ability is what gives you your insane crowd control and lock down potential. It deals damage and stuns targets with 4 stacks of Frost.

R – Glacial Prison

Sejuani throws her True Ice bola that deals magic damage to the first enemy champion hit and stuns them for 1 second.

The bola becomes more powerful as it travels, dealing 50% more damage, stunning for 1.5 seconds and creating a storm that slows other enemies by 30%. After 2 seconds, the storm deals magic damage and slows by 80% for 1 seconds.

Glacial Prison is Sejuani’s most important ability. You can miss all your other abilities but it is important that you land her ultimate. This is best used when setting picks in the jungle or when playing around with the enemy’s vision in the fog of war. When engaging in a gank, you are better off going with her standard combo and using the stun from Permafrost to lock down enemies. However, feel free to use this ability when they manage to escape or dodge your other abilities as a last resort to pin them down while your teammates deal damage.

Runes and Item Builds

When it comes to items, your focus should be to increase Sejuani’s durability and survivability. Some players like to build her full AP but for this guide, we decided it would be better for you to stick with her tank builds first and once you get used to the champion, you can explore other play styles.

Starting Items

For her starting items, you should always go with Hailblade. Sejuani is not known for being a duelist so purchasing an Emberknife for the Challenging Smite would do her no good. With Hailblade, you get Chilling Smite which is far better for her since it slows opponents down, leaving them vulnerable to your other abilities.

Mythic Items

Arguably, all the Tank Mythic items are pretty much great on Sejuani in terms of viability. However, we found that these three Mythics are the best and most effective. Out of these three, Sunfire Aegis is probably the most popular. It gives her all the stats she needs plus some very good DPS thanks to the Immolate and Flametouch passive. Evenshroud is another good option that can make her ganks more powerful thanks to the Coruscation passive which lets her and her team deal more damage to enemy champions that are immobilized. If you want to stick to your targets better, Turbo Chemtank would probably work best for you. With this item, you get an Active called Supercharged which lets you move faster when moving towards enemies or towers for 4 seconds before releasing a shockwave that slows nearby enemy champions. Choose whatever Mythic item you like but when in doubt, the safest choice is Sunfire Aegis.

Full Build

After purchasing your Mythic item, it’s time to upgrade to tier 2 boots. Plated Steelcaps is the go to option but Mercury’s Treads are a good alternative if you need the magic resist or tenacity. Next, go with Thornmail for the armor and health plus the return damage when enemies hit you with their basic attacks. Follow that up with Randuin’s Omen for the damage reduction, armor, health, and active slow. Next, work your way to building an Abyssal Mask for the magic resist and the magic resist reduction on enemy champions around you. Finish off your build with a Gargoyle Stoneplate for the bonus armor and magic resist plus the active shield which essentially functions as a second life bar.

Other Viable Items

Most tank items are actually quite viable on Sejuani. You have a wealth of options to choose from like the ones pictured above whenever you need to swap a few items out. We urge you to try out and familiarize yourself with these items so that you’ll know when to use them when the situation arises.


For runes, go with the Resolve tree and take Aftershock as your keystone. This will allow you to gain more defenses and deal a bit of damage whenever you engage an enemy. Next take Font of Life for the bonus damage on targets with impaired movements, Conditioning for bonus resistances in the mid game, and Overgrowth for bonus max health. For your secondaries, take Triumph and Legend: Alacrity from the Precision tree. Triumph gives you bonus sustain and Legend: Alacrity for bonus attack speed. For your rune shards, take Attack Speed, Armor, and Defense.

Useful Tips

  1. Keep in mind that your melee allies can stack Frost that you can proc with Permafrost so try to keep an eye on who they are attacking. 
  2. Sejuani is countered in the Jungle by champions like Diana, Lillia, Rengar, and Graves
  3. For your summoner spells, always take Flash and Smite. This will let you clear jungle camps faster and let you secure objectives like Baron or Dragon.
