How to win lane as Gnar against Sejuani · 53.41% win rate (264 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Bully her early — kite her mini and Mega-stun the Permafrost cooldown.
Track: Sejuani's E — Permafrost. Her stun after Frost stacks. Don't get stacked + stunned.
Read from Gnar's seat: which stage windows this plan plays for against Sejuani.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Gnar | Her Arctic Assault is one-point and on a long cooldown early while she has no ranged answer, so Mini's auto-plus-Boomerang wins the first trade clean before any Frost stacks land. |
| Level 2 | Gnar | Your level-2 Hyper third-hit proc plus Boomerang chunks her for free, and she has no Permafrost detonation set up yet to punish the commit. |
| Level 3 | Gnar | Kite on Hyper move speed — Frost Armor makes her slow-immune, so your Boomerang slow only bites after her armor breaks; her Q dash is 18s. |
| Levels 4-5 | Sejuani | At 6 she gets Glacial Prison — if you're stuck in Mini with Rage gone she Q-dashes in, R-pins you, and detonates Permafrost for the kill, so this is her window. |
| Level 6 | Even / skill | If Rage is up instead, Mega Wallop stun into Boulder Toss out-trades her by a health bar, and a wall-pin GNAR! near terrain is a near-guaranteed kill while her R is down. |
| First item | Gnar | Your first-item poke spike keeps snowballing the lead — her single dash and lack of sustained range can't trade it back in lane. |
| Two+ items | Even / skill | She scales into an unkillable teamfight tank with Frost Armor and a long-range Glacial Prison, so your form-dependent burst plateaus into her late-game frontline. |
Sejuani's only gap-closer is Arctic Assault (Q), one dash on 18 seconds at rank 1, and she has no ranged poke — so Mini Gnar bullies her. Auto, throw Boomerang, and catch it on the return for the cooldown refund; note Frost Armor makes her slow-immune, so the slow only bites once damage has broken it. Lead with the Hyper third-hit at level 2, then leave on the move-speed burst. Permafrost has no real cooldown at 1.5 seconds — the gate is Frost stacks, so break off after her second Winter's Wrath (W) swing.
