Hi I am Mario and that is my Sejuani's build. I think Sejuani is underestimated, but she is really realiable jungler.She is one of the best gangers in the game with her Permafrost and her ultimate. The screenshots have been made in normal draft games at level 30.

Skill Sequence

Your passive doesn't change with levels, and reduces the enemy's movement speed by 10% for 3 seconds. That isn't much, but that's sure something!It won't stack with each atack it will just refresh the duration.

Sejuani charges forward to deal magic damage and apply Frost to enemies. Sejuani stops upon colliding with an enemy champion.
Base damage: 60/97.5/135/172.5/210
AP ratio: 0.4
Mana cost: 70/80/90/100/110
Cooldown: 19/17/15/13/11

Notes: •This spell has a maximum of 450 range. If you don't know how much is that, behold: it is exactly the same as Vladimir's autoattack range! I know that helped, right :P
•You can define the travel distance by dragging the skill line (pretty much like Olaf's Axe). Don't forget this, or you might sometimes fail just because you forgot to drag the line out.
•This skill can pass through walls. Actually, it can pass through almost any wall on the map.

Sejuani summons an arctic storm around her for 5 seconds, dealing magic damage each second to nearby enemies. Damage is increased by 50% against enemies affected by Frost or Permafrost.
Magic Damage per Second: 12 / 20 / 28 / 36 / 44 (+0.1 per ability power) (+1 / 1.25 / 1.5 / 1.75 / 2% of Sejuani's maximum health)

Maximum Magic Damage : 60 / 100 / 140 / 180 / 220 (+0.50 per ability power) (+5 / 6.75 / 7.5 / 8.75 / 10% of Sejuani's maximum health)

Magic Damage to Frosted target per Second: 18 / 30 / 44 / 54 / 66 (+0.15 per ability power) (+1.5 / 1.875 / 2.25 / 2.625 / 3% of Sejuani's maximum health)

Maximum Magic Damage to Frosted target: 90 / 150 / 210 / 270 / 330 (+0.75 per ability power) (+7.5 / 9.375 / 11.25 / 13.125 / 15% of Sejuani's maximum health)

Notes: •This skill has a 350 range.
•With 40% CDR you will only have to stop using this skill for 1 second.
•Awesome for farming minions, especially if combined with Arctic Assault.
•This scales both with ap and your maximum health, and scales are highter when the target is affected with frost or permafrost

Sejuani converts Frost on nearby enemies to Permafrost, dealing magic damage and increasing the movement Speed reduction.
Base damage: 60/110/160/210/260
AP ratio: 0.5
Movement speed reduction: 30%/40%/50%/60%/70%
Mana cost: 55
Cooldown: 11

Notes: •This skill has a 850 range.
•This skill is only active when there are Frosted targets in range, so you can't "waste" it if you press the button occasionally.
•The slow amount at rank 5 is 70 percent.

Sejuani throws her weapon, stunning the first enemy champion hit for 2 seconds and all other nearby enemies for 1 second. All affected targets take magic damage and are affected by Frost.
Base damage: 150/250/350
AP ratio: 0.8
Mana cost: 100
Cooldown: 150/130/110

Notes: •This skill has a 1200 range.
•This skill has an awesome name (IMO)
•The impact size is bigger then the width of the skillshot line. That means, it will hit even if you slightly miss.

Summoner Spells

Ignite - Sejuani is weak early game and she has low dmg.
Smite - Sejuani is jungle champion. She is weak early game and you can't go without it.
Exhaust - It's awsome for gangs and lategame in teamfights, it's very usefully if you put exhaust at enemie's ad carry.
Flash - Sejuani has Arctic ***aut it's like flash. Use it carefully.

- weak early game
- low damage early game
- mana dependant early game
- items dependant

Bot lane: This is your main priority. Shutting down this lane affects the entire enemy team. How? Because getting a double kill in this lane leads to getting a free Dragon in many cases.

Mid lane: Generally, theres only one champion per team that will deal a significant amount of AP damage. So obviously, shutting that champion down will give your team a major advantage. This lane is next on the list, but its also the hardest lane to gank because of its small size.

Top lane: This is the furthest lane from Dragon, which is a very important early game objective. By choosing to play top lane, you're basically telling your teammates that you can take care of yourself. So dont ***** and complain if you get your *** kicked and your jungler only ganked once or twice. The jungler cant babysit top unless mid and bot are doing well on their own.

■ Arctic Assault knocks back minions and neutral monsters in direct line of the charge and a small area at the end of charge route.
■ Arctic Assault can go through most walls.
■ Autoattacks will not stack Frost, but refresh the duration of slow.
■ Arctic Assault applies your passive and goes through terrain. This means you can Arctic Assault through a wall and Permafrost to hit every minion.
■ Your Permafrost can only be used on targets with Frost, and Northern Winds does not apply frost. This means you have to auto-attack, charge or ultimate something before being able to slow it.

Team Work

Sejuani works perfect with high dmg team ( for example: Taric/leona support , Tristana/Ezreal/Graves carry , brand/ryze/Kennen mid , riven/trynd/pantheon top )Her gangs are really strong but if u gang top and your mate are tank or champion without cc(stun,slow)( ww before lvl 6 or galio before lvl 6 ) your enemy will run easy if he has escape mehanism or if he has high mobility or he use flash. So she works best with high dmg teams. Try to get ad carries with your ultimate.

Start items

and 5 health potions

First recallor

Core items

- It gives you hp regen and mana regen and the passive. It is very useful.
- It gives you health and the passive is perfect, because your build is expensive.
- With this item you will be jungling faster and it gives you bonus armor and atack damage.
- The best boots for junglers( in my opinion). It gives you bonus magic resist and tenecity - you are vurneble to cc.

Mid game

- My favorite item for jungling. It gives you atack speed ( you have no ad ratios ), magic resist and awesome passive - bonus magic damage per hit. And when you gang mid against brand or le blanc they won't kill you ... :D
- It gives you more health, a little ad and perfect passive for you - slow per hit. With this item,your passive and Permafrost your enemy will move backward :D thats joke but he will be really slowed.

Late game

- 99 armor ,500 mana , 20 percent cooldown reduction and atack speed reduction aura. It gives you all you need. Your abillities have high cooldowns and cooldown reduction is perfect on sejuani. Also this item is countering enemy's ad carry and mele fighters like tryn , jax and others .
- This item gives you magic resist - you need it late game in teamfights , also gives you health regen and movement speed. With masteries, runes you will be really fast , it helps always.
- This item improves you autatacks . With more atack speed and atack damage , also gives you some more armor. Also gives you one more per hit effect (4 percent of magimum health).With this passive you will kill faster your targets.

Other good items

Magic resist

Banshee's Veil +375 Health +375 Mana +50 Magic Resist UNIQUE Passive: Gain a spell shield that blocks the next incoming enemy ability (45 second cooldown). It will be useful against crown control teams.
+68 Armor +38 Magic Resist UNIQUE Passive: Revives your champion upon death, restoring 750 Health and 375 Mana (5 minute cooldown). I think this item is not for tanks but on 3v3 it works perfect.


Aegis of the Legion +270 Health +18 Armor +24 Magic Resist UNIQUE Aura: Nearby allied champions gain 12 Armor, 15 Magic Resist, and 8 Attack Damage. One of the best items in the game. This item is recommendet, but u must told your support you will take it. It would be waste of gold if both of you take it.

Sunfire Cape +450 Health +45 Armor UNIQUE Passive: Deals 35 magic damage per second to nearby enemies. This item is one of my favourites, i didn't put it on my build because i think Frozen heart work better with Sejuani(she needs cd reduction). It works perfect against olaf ( true damage ).
Randuin's Omen+350 Health +75 Armor +25 Health Regen per 5 seconds UNIQUE Passive: +5% Cooldown Reduction . It is other good item it gives you really nice stats but it gives only 5% cd reduction. Also it gives you unuque active(it slows enemies around you).

Cd reduction

Shurelya's Reverie +330 Health +30 Health Regen per 5 seconds +15 Mana Regen per 5 seconds UNIQUE Passive: +15% Cooldown Reduction UNIQUE Active: Nearby allied champions gain 40% Movement Speed for 3 seconds (60 second cooldown).It is other good item for sejuani. It gives you regens and hp if you want to be fast and with more health take it.

Tank-Support Sejuani(second build)

This build is more supporting your team with this build you will be more hard to kill with more hp , hp regen , armor and mr but with this build you have less damage. This build is for people who don't like on-hit Sejuani. It works perfect too , but i prefer oh-hit Sejuani. With this build your role is to protect your Ad carry.

Guide Top

Ap Sejuani

Sejuani works good with ap, but it is very important to have ap runes at level 1. With my build you will have balanced armor, magic resistance and health and about 200 ap witch is not little, and you will have great auras like frozen heart's and shurelia's. I'm trying to get high health and ap because your W is your best damage and it scales both from your health and ap. If you want to be succesfull jungler you must gang a lot, that's why i get 2 items for gold per seconds and the mastaies with gives you 24 bonus gold per assist or kill. It's recommendet to gang botlane at level 2, if your support is taric the kill is guranteed, when you reach level 4 try to gang mid if you and your mate at mid successed with this gang, it have a high percent of chance that your mid will win his lane.
