Hello guys!

I'm Gedrah, a Diamond OTP Sejuani player. I have been playing her since season 3 on both EUW and NA servers combined. I also have 1M+ mastery points across both accounts.

I love playing Sejuani. She has many CC, a lot of mobility and she is really tanky.

In this guide, I will tell you about my playstyle as a tank/support jungler. Which decision should you make in the early game? How do you win games in mid/late? What do you do when you or your teammates are behind?

I will answer those questions in the guide as best as I can.


+ Lots of Crowd Control
+ Really tanky
+ Damage/Tankiness scale with HP
+ High Mobility with her dash
+ Very good peel and engage abilities


- No natural sustain (need warmog)
- Weak against Fighters/Bruisers
- Vulnerable to counter jungle
- High cooldown in early game (Q and R)
- Very team oriented
Sejuani is an absolute CC Queen. Her abilities can prevent many enemies to move for a long time. She can be played offensively to shut down enemies but also defensively to protect your carries.
She will be a great addition to a composition when you already have a hyper carry champion like Katarina or Yasuo.

The main issue is the enemy jungler. If your opponent is very aggressive on the map and hard to 1 vs 1 (like Olaf or Trundle) you will have a very hard time.

Fury of the North

Sejuani has 2 PASSIVES : Frost Armor & Icebreaker.

Frost Armor : Sejuani becomes immune to slows (attack speed and movement speed) and gains 10 (+50% of bonus armor) in armor and 10 (+50% of bonus magic resistance) in magic resistance. Frost Armor lingers for 3 seconds before breaking.

Icebreaker: Enemies stunned by Sejuani are frozen. Sejuani's next basic attack or ability against them deals 10% of their maximum health as bonus magic damage (max 300 damage against epic monsters).

Arctic Assault

Range: 650
Cooldown: 18 / 16.5 / 15 / 13.5 / 12
Cost: 70 / 75 / 80 / 85 / 90
Sejuani charges forward, knocking enemies into the air for 0.5 seconds and dealing 90 / 140 / 190 / 240 / 290 (+60% of ability power) magic damage (max 300 damage to monsters). The charge stops after colliding with an enemy champion.

Arctic Assault is your main source of mobility around the map. Use it for gank, to move faster around the map and to traverse walls. You have to be careful in early game when you use it because it has a high cooldown.

Winter's Wrath

Cooldown: 9 / 8 / 7 / 6 / 5
Cost: 65
Sejuani swings her flail in a cone in the target direction, dealing 20 / 25 / 30 / 35 / 40 (+ 2% maximum health) (+20% of ability power) physical damage to all enemies hit and knocking back minions and monsters.

She then lashes out with her flail in a straight line in the same direction, dealing an additional 30 / 70 / 110 / 150 / 190 (+ 6% maximum health) (+60% of ability power) physical damage and applying Frost.

Winter's Wrath is your main tool to apply Permafrost to your enemy if you don't have melee allies. This spell has a first swing that will deal damage to enemies and knockback jungle monsters and minions. Your first swing will help you to deal AOE damage and push the monster to your next camp in order to clean your jungle faster and gain some time.
Your second swing deals additional damage and slows your enemies.


Range: 600
Cooldown: 1.5
Cost: 20
Passive: Sejuani and nearby melee allies apply Frost with their basic attacks, stacking up to four times. Sejuani can cast Permafrost on enemies with max Frost stacks.
Active: Sejuani can freeze an enemy champion, epic/large/medium monster, super minion or siege minion, dealing 55 / 105 / 155 / 205 / 255 (+60% of ability power) magic damage and stunning them for 1 second. Once consumed, enemy champions cannot gain Frost for 8 seconds. Permafrost resets Sejuani's basic attack timer.

Every melee champion can apply frost stack. Play around melee champions who can snowball (like Jax, Sett or Yasuo) to increase its efficiency.
IT'S NOT Permafrost that deals most of the damage but Icebreaker (Inner Sejuani's passive) from Fury of the North so you should max E last.

Glacial Prison

Range: 1300
Cooldown: 120 / 100 / 80
Cost: 100
Sejuani throws a True Ice bola in a line, dealing 125 / 150 / 175 (+40% of ability power) magic damage and stunning for 1 second the first enemy champion that collides with.
Bolas are empowered after traveling 400 distance, increasing their damage to 200 / 300 / 400 (+80% of ability power) and stun duration to 1.5 seconds. Stunning a target with Glacial Prison triggers Permafrost's per-target stun cooldown.
Empowered bolas also leave behind an ice storm that explodes after a brief delay. The storm lasts 2 seconds and slows enemies by 30% while inside the AoE. The explosion deals 200 / 300 / 400 (+80% of ability power) magic damage and slows enemies by 80% for 1 second.

Glacial Prison is Sejuani's ultimate. Use it to engage in teamfights, gank a lane or chain CC your enemy with a combo. This skillshot is really powerful and can turn many fights into a victory if you use it on the right target.
You can also apply a freeze to an enemy twice by using Permafrost THEN Glacial Prison. You CANNOT freeze an enemy the other way around.

Take R Glacial Prison at level 6, 11 and 16 like most champions.

Max W first. Winter's Wrath's damage scales based on your Max HP.

Max Q Arctic Assault second because the spell has a high cooldown. By the time you max the spell (level 13), you will also have some ability haste so the cooldown won't be an issue.

Max E last. Permafrost has the same cooldown and the same cost at every level so it doesn't change that much when you level this spell up. When the enemy is frozen, it's Sejuani's second passive Icebreaker that deals most of the damage (which is 10% at every level).

Start with Permafrost for your first camp. You will be able to stun the blue buff or Red buff for 1 second AND you will apply Icebreaker which deals a lot of damage. If your support is a melee champion it will be even faster because he will help you with your Frost stack.

Take Winter's Wrath second so you will be able to push monsters to the next camp, do some AOE damages and apply Frost stacks.

At level 3, take Arctic Assault. You will need it to gank a lane and traverse walls.


With this first combo, you can apply all your damage without ultimate. Your goal is to get to 4 Frost stacks so you can stun your enemy. You get 1 stack per Auto attack

Use this combo in a gank. Your goal is to surprise your enemy by showing up from a hidden spot. You have to use Arctic Assault and Glacial Prison to stun your enemy. I would recommend being camera free when you use this combo. The downside of this combo is that you won't be able to apply Frost stacks.

This is the ultimate Sejuani's Perma CC combo that will stun your enemy for up to 3 seconds ! This combo is pretty similar to the first one but you add your ultimate. Use it when the enemy is squishy.

Flash is the summoner spell used on almost every champion and Sejuani is no exception. You can use it to escape from a fight or a counter jungle when you don't have your Arctic Assault. You can also add flash to your Q spell to surprise your enemy or to extend the range (Example on Q Spell Tips & Tricks).
Challenging Smite
Smite is the mandatory spell for every jungler so you also need it.
Challenging Smite is way stronger than Chilling Smite for Sejuani. You will be able to 1 vs 1 most assassins and adc.
Chilling Smite is also a viable option, but the other smite gives you more damage to kill enemies. Sejuani already has many CC so you won't necessarily need to add another one.

Aftershock gives her more resistance when she immobilizes an enemy and deals damages when it exploses. It scales very well with her passive and overall kit. A must-have.
Demolish will help you to get turret platings and early towers when you push with Herald. Since it scales with your HP, it will do more damage the more HP you have. In most games, this rune will help you push your lead by getting more towers in early game.
Conditioning scale really with her overall kit. You want to get as much armor and magic resistance as possible.
Overgrowth is great since it will give you permanent HP by farming your jungle. This works well with Demolish.
Since Sejuani is supposed to tank most of the enemies' damage, Triumph will help her to survive some deaths if you or your allies kill an enemy. This rune really shines on team fights and dives.
Legend: Alacrity will help Sejuani to clean her jungle faster and to apply Permafrost to enemies.
clean faster in your jungle
choose if there is more enemies AP champions
The armor boost will be useful against AD enemies and monsters

Sejuani Item Set
How to import the set
Refillable Potion
Start with Emberknife in order to get your Challenging Smite. It will provide both damages and damages reduction against a champion.

First Back
Ruby Crystal

Control Ward

Oracle Lens
If you have below 1300 gold, start with boots to increase your movement speed and a ruby crystal or 2. You want to rush your Mythic item as fast as possible. The Control Ward and Oracle Lens will help you with objectives (Drake or Rift Herald). It would help if you had more vision control around the map.

Ideal Back
Bami's Cinder

Control Ward

Oracle Lens
If you have more than 1300 gold, take those 4 items. Bami's Cinder is very good in early game for clearing camps and dealing more damage. Having it early will help a lot with everything you do.

Mythics Items
Sunfire Aegis
FrostFire Gauntlet
Aim for the Sunfire Aegis as your primary mythic item. This item deal WAY more damage than the other one. You will be able to solo objectives easily, fast and even duo the Baron Nashor with an adc or a carry like Yasuo.

Iceborn Gauntlet is another item you can build when you are very behind and you know you will have to play a more support role.

Plated Steelcaps
Mercury's Treads
Take Plated Steelcaps if the enemy team has mostly AD champions. It will bring you armor and damage reduction from basic attacks.

Take Mercury's Treads if the enemy team has champions with many CC like Leona or Morgana. You will have the tenacity to reduce CC duration.

Core Items
Warmog's Armor

Force of Nature

Anathema's Chains
Warmog's Armor will give you the HP you need to tank in team fights and the ability to sustain better in mid/late games. It also increases the damage dealt with Demolish on towers. If you reach 1100 HP, this item will regenerate 5% of your HP every second if you are not in combat for 6 seconds.

Thornmail is a pretty good item which gives armor, anti-healing and HP. You may find others armors items like Frozen Heart or Randuin's Omen better in some situations. This item is a very good standard armor item.

Force of Nature is the best item against heavy AP damage. This item will gives you a lot of magic resistance and movement speed. It also grants you MR and MS bonus if you take magic damage during a fight.

Anathema's Chains is an extremely strong item on Sejuani. You should really think about this item when the enemy team for example has 1 AP and the others are full AD and vice versa. You will be able to tank 1 enemy specifically and reduce his tenacity. He will also deal 30% less damages to you and the tenacity will be 20% less effective. If you combine it with Challenging Smite you will significantly reduce the enemy damages while increasing yours. You won't have to build one MR item just for 1 enemy if they are mostly AD.

Against AD
Randuin's Omen

Frozen Heart
Dead Man's Plate

Death's Dance
Randuin's Omen is a great item when you fight against ADC and champions relying on critical strikes (like Tryndamere, Yone and Yasuo). The passive reduce incoming damage and the active slow every nearby enemy and reduce their critical strike damage by 20%.

Dead Man's Plate gives you armor, health and movement speed. It also slows your enemy with your next auto attack once the item is fully stacked. You may want to build this item against Hecarim.

Take Frozen Heart if the enemy team has a lot of auto attackers who don't necessarily have critical strikes. The item reduces incoming damage and cripples the enemy's attack speed by 15%. Really good against Vayne players. The item is also cheaper than Randuin so it will depend on your situation during the game.

Death's Dance is the extremely situational armor item that you build when the enemy team is full AD, the game is not over yet and you need the last item. You will be able to mitigate the little physical damages that they will try to do to you.

Against AP
Spirit Visage
Abyssal Mask
Take Spirit Visage if you need a bit of magic resistance and if you have some healing ally support like Soraka or Nami, this item will definitely have some good use for you. It will increase every heal and shield by 25%.

Abyssal Mask is a situational item that you want to build when most of the damages in your team are AP and you need MR. You will reduce enemy magic resistance while increasing yours.

Situational Items
Knight's Vow
Gargoyle Stoneplate
Knight's Vow is a nice option, if you need to peel for your carry. This item redirects 10% of the damages to you. It also increases your movement speed when you move toward your ally.

Gargoyle Stoneplate is a late game item. This item grants you a shield (based on 100% of you bonus health) that decays over 2.5 seconds and gives you a bonus of armor and magic resistance if you take damage. It increases your survivability in teamfights.

You can do 3 camps, get your level 3 and then gank.
You can do 5 camps + scuttle to get your level 4. If you clean your jungle fast enough you will be able to arrive at the scuttle right after his spawn.
Then you can gank a lane (top or mid). If you don't find an opportunity, just back, buy your next items and keep farming your jungle. Restart with krugs then keep the same path. Camps will respawn.

If you time correctly your Q spell, Sejuani can cancel dash or abilities. Keep your Arctic Assault until the enemy uses its ability.

If you use your flash during your dash you can extend its range. You will be able to surprise your enemy.

You can pass almost every wall in the game. Some of them need you to be really close.

When it comes to teamfights there are 3 strategies that you can apply depending on the state of game and your team composition : Catch an enemy, Engage fights and/or Peel your carries
Catch an enemy

A way to increase your chance of winning a teamfight is to catch an isolated enemy. Check on the map if there is one enemy who farms minions in a lane or if an enemy is coming to an objective without vision (it's very important to have a Oracle Lens to clear wards before you do this). Hide in a bush and get ready to use Glacial Prison or let a melee ally with CC stun so you can apply Permafrost without losing your ultimate. Killing an enemy without losing too much resource will make your teamfight easier since it will be 4 vs 5 instead of 5 vs 5. It might even abord the fight altogether.
Engage fights

Sejuani is very good to engage teamfights thanks to her Glacial Prison. Use your ultimate to catch a dangerous enemy. If you are able to land it fast enough and your team can follow you, you will be able to erase an enemy from the fight.
Peeling for your carries

When your carries are really far ahead or play very well, you have to protect them in teamfight from assassins. Keep your Glacial Prison just for the enemy who attacks your carry. If necessary buy Knight's Vow when your support doesn't have it to increase the protection of your carry.

When you play as a jungler you want to focus on 3 things :
farm your jungle, gank lanes and get objectives (herald, drakes and towers).

Starting in champion select you already want to know which lanes you are going to gank. Check on your team which champions have more potential to carry the game. You should also check your enemies. He might be worth putting a strong opponent behind.

Then, in the game, while you are doing your camp, keep an eye on every lane. If you see one of them winning the matchup, snowball by coming to their lane to help putting the enemy even more behind.

When you gank with Sejuani, go behind the enemy and keep your Arctic Assault (if possible) so you can use it when the enemy flashes.
Neutral Objectives

If you find it difficult to gank and find opportunities, focus more on neutral objectives.

Getting Rift Herald early is also a great way to snowball on the game. If you combine Demolish and Rift Herald you will be able to hard to push a lane. You might be able to get 1, 2 or even 3 towers in one push! Remember that the more plates you destroy the harder it will be to destroy the next. That's why you should Hearld on the 2 last plates. It will destroy the turret instantly.

Getting drake as early as possible will help you in the long run to get the soul. You will also force teamfights at the drake so if your team is doing great you might be able to end the game pretty quickly.

You can solo every elemental drake starting level 4. You have to make sure that the enemy jungler is not close because you will be very easy to kill.

Team compositions

Starting in champion select, identify which lane you want to focus on first (Note: that it can change through the game). Look at the melee champions in your teams. Is your toplaner a strong melee champion who can snowball hard on his matchup like Camille or Fiora ? Is your midlaner able to follow up on your gank like a Yasuo or a Katarina ? Is, the enemy jungle, a huge threat like Xin Zhao? Ask yourself these questions to choose which side on the map you are going to be more present.
Observe your laners

Start at your camp following my jungle path chapter. While doing your camps move your camera to laners to see the state of lane. Are they fighting constantly ? Is your laner or the enemy laner low ? Is your laner or the enemy laner pushing ? Check as often as possible these informations while keeping your original plan (which is to farm your camp until level 4 and gank). After getting level 4 from your camps, check if there is gank opportunity. Is the enemy laner close to your towers ? If yes, the gank has more chance to result to a kill. DO NOT USE Arctic Assault RIGHT AWAY WHEN YOU GANK. Keep it as much as possible to follow after the enemy flash.
Snowballing lanes

If you have a successful gank with a kill, be ready to come back to snowball your laner even harder. If you can get 1 or 2 more kills it will make your laner far ahead and you will able to secure objectives. If a lane is very behind, ignore it and focus on making your other laners ahead.
Secure Objectives

Every time you get kills, watch where you can convert the kill into another objective ( Drake , Tower or Rift Herald ). If you see the enemy jungler on the other side of the map ganking, focus on taking his jungle, ward it and then get a neutral objective.

Pressure Objectives and Teamfights

At this point, you want to engage in teamfights around objectives. It's Sejuani's Strength. When preparing for the next objective ( Baron Nashor or Drake ), I recommend backing exactly 1 minute before the drake spawn. You will have time to buy your items (and Control Ward or Oracle Lens). You will arrive before the drake spawn and will be able to put some wards to have visions. You might even be able to catch an enemy with Glacial Prison and get a free drake.

If you focus on getting towers you will be able to do huge damages on them thanks to Demolish and might be able to dive.
At this point of the game diving under tower is a piece of cake for Sejuani. Even better if you have Warmog's Armor because you will be able to regenerate pretty quickly. I still recommend being careful when diving. Take into consideration the enemy CC and the number of enemies under the tower.

In late game, it's pretty much the same but you should be even more careful. One mistake can cost you the game. You have to ward around the 2 most important objectives at this point of the game : Baron Nashor and Elder Drake .

Your successful teamfights should always convert toward an objective on the map (Turrets, Drake or Nashor).
