Sejuani splash art for this Sejuani guide

Sejuani plays the jungle as the Fury of the North frontline-tank engage pick on patch 26.22. Arctic Assault charges forward on her boar, knocking up any enemy caught at the end of the dash. Winter’s Wrath winds up for 2 seconds then releases a wide cone that slows and damages enemies. Permafrost explodes Frost stacks on an enemy for stun and bonus damage. Glacial Prison throws an ice bolt that stuns the first enemy hit and shatters surrounding ice for AoE stun.

Sejuani’s Data Dragon file lists her under Tank tag, 4 out of 10 difficulty rating, 150 melee auto range, and Mana as the pool. Her Fury of the North passive makes Sejuani enrage out of combat, granting her bonus Armor and Magic Resist when she takes damage after being out of combat; her auto-attacks also apply a Frost stack toward Permafrost detonations.

Abilities and role

Where does Sejuani fit? Jungle solo-queue frontline engage. For what it’s worth, her jungle pick stays viable whenever the meta rewards tanky engage; a Sejuani with Fury of the North stacked at full enters teamfights with heavy resistances and chains Arctic Assault into Glacial Prison for a 2-stun engage.

Fury of the North (Passive)

Sejuani gains bonus Armor and Magic Resist when she takes damage after being out of combat (ramps during the enrage window). Her auto-attacks also apply a Frost stack toward Permafrost detonations. For what it’s worth, Fury of the North is Sejuani’s primary tanking engine; a Sejuani who flanks from fog of war enters the fight at full resistances and absorbs committed burst.

Arctic Assault (Q)

Sejuani charges forward on her boar, dealing physical damage to enemies hit and knock-up the first enemy at the end of the dash. 18 to 12 second cooldown, 60 mana. The Q is Sejuani’s primary engage; an Q dash into the enemy backline knock-ups the enemy ADC and sets up the follow-up Glacial Prison stun.

Winter’s Wrath (W)

Sejuani winds up for 2 seconds then releases a wide cone that deals magic damage, slows and applies Frost stacks on enemies hit. 9 to 5 second cooldown, 40 to 60 mana. The W is Sejuani’s primary farming and Frost-stacking tool; a Winter’s Wrath cone against a stacked enemy comp lands 3 Frost stacks on each target in a single cast.

Permafrost (E)

Sejuani detonates Frost stacks on a target enemy, stunning them for 1 second and dealing bonus magic damage per stack. Requires at least 3 Frost stacks to activate. 1.5 second cooldown, 25 mana. The E is Sejuani’s primary stun button; weave Permafrost onto the enemy ADC after Winter’s Wrath cone stacks Frost on them.

Glacial Prison (R)

Sejuani throws an ice bolt that stuns the first enemy hit for 1.5 seconds. The surrounding area also shatters, slowing other enemies in a radius. 120 to 90 second cooldown, 100 mana. The R is Sejuani’s primary teamfight pick tool; a long-range Glacial Prison from fog of war onto the enemy ADC locks them in place for the follow-up Q engage plus Winter’s Wrath cone.

Build and item spikes

Sejuani’s jungle start pairs Mosstomper Seedling (farming) or Scorchclaw Pup (ganking) with Smite plus Flash. First item is Sunfire Aegis for the burn aura that stacks damage on nearby enemies during committed engages.

Second slot picks Jak’Sho, The Protean for the stacking Armor and Magic Resist that pays off during Fury of the North enrages. Slot three flexes to Thornmail against AD-heavy comps for the Grievous Wounds reflect, Spirit Visage against AP drafts for the MR plus self-healing multiplier, or Dead Man’s Plate for the sticky Movement Speed on committed Arctic Assault engages. Full first-through-sixth-item path lives on our LoL items database.

How to play by game stage

Levels 1 through 6 on Sejuani focus on jungle clear with Winter’s Wrath cone sweeps on each camp. First gank opens at level 6 once Glacial Prison lands a long-range pick from fog of war onto the enemy mid-laner.

Across levels 7 through 13 Sunfire Aegis is Sejuani’s mid-game spike. Rotate to Drake with the ally bot-lane. R Glacial Prison picks the enemy ADC during the 2v2 skirmish, locking them for the follow-up Q plus auto chain.

Past level 14 full-build teamfights revolve around R Glacial Prison picks on isolated enemy carries. Winter’s Wrath cone fans Frost stacks across the enemy frontline. A Jak’Sho fourth item lets Sejuani tank the enemy frontline’s committed burst inside the enrage window.

Who counters Sejuani

Who shuts down the Sejuani jungle? Three distinct pressure types bleed Sejuani. Early-pressure junglers who invade her level-1 clear (Lee Sin, Elise, Nidalee). Peel enchanters who shield-cleanse Glacial Prison targets (Lulu Whimsy polymorph, Milio ult cleanse). Hyper-mobile ADCs who dash out of Arctic Assault knock-up range (Ezreal E, Tristana W, Kai’Sa R).

  • Invading junglers: Lee Sin, Elise, Nidalee. Each punishes Sejuani’s slow level-1 clear by invading her first camp.
  • Peel enchanters: Lulu, Milio. Each cleanse Glacial Prison stun with their ult or polymorph.
  • Mobile ADCs: Ezreal, Tristana, Kai’Sa. Each dash out of Arctic Assault knock-up range.

ARAM notes

Howling Abyss Sejuani opens with Sunfire Aegis for the burn aura on clumped bridge fights. Jak’Sho arrives second for the stacking resistances during stacked enemy burst. Thornmail lands third against AD-heavy enemy comps for the Grievous Wounds reflect. R Glacial Prison from fog of war onto the enemy backline isolates a kill behind the Sejuani team’s frontline.

Sejuani thrives on the Howling Abyss map alongside sustained-damage ally ADCs (Jhin, Caitlyn, Ashe) that convert her Glacial Prison pick into kills. Our Sejuani ARAM build page carries the full item path and matchup table.

FAQ

Is Sejuani easy to learn?

4/10 and the beginner-friendly tank-jungler. Her R Glacial Prison is a point-click stun on marked enemies — mark comes from autos. New Sejuanis R without a mark (misses); mains W-auto-E-mark, then R the whole enemy team. Her E Permafrost is a point-click AoE stun on marked enemies — chain E before R for a double stun.
