Master Yi vs Sejuani

Updated Jun 4, 2026

Overview

Use Master Yi's faster clear speed and mobility to outpace Sejuani's jungle tempo and deny her early jungle control.
Prioritize invading and counter-invading around river scuttle to secure vision dominance and force Sejuani into reactive pathing.

Jungle Plan

Full clear quickly to hit item spikes and avoid early fights where Sejuani's CC and tankiness dominate.
Fight for first Scuttle only when nearby lanes have priority to support and secure river control.
Use lane priority and vision to collapse on Sejuani when she overextends for camps, forcing her off tempo.

Danger windows

Avoid isolated river fights early where Sejuani can chain her CC and tank damage.
Be cautious when low on health during clears, as Sejuani can punish with counter-invades or ganks.
Respect Sejuani's level 6 all-in potential and avoid forced smite fights without lane assistance or vision control.

Early game

Start with a full clear to hit level 3 faster and contest the first scuttle crab before Sejuani arrives.
Avoid early river fights if Sejuani shows aggressive pathing; instead, focus on vertical jungling to maintain tempo.
Use your mobility to counter-invade when Sejuani commits to one side, punishing her slower clear speed.

Power spikes

At level 6, use (R) to chase and reset on low-health targets after Sejuani commits her CC.
Respect Sejuani's level 6 (R) engage; avoid grouped fights without vision or lane support.
Exploit your early clear speed spikes around levels 3 and 4 to invade or secure scuttle control before she can respond.

Win conditions

Convert faster clears and superior mobility into aggressive counter-jungling to starve Sejuani of resources.
Use lane priority from teammates to set up deep vision and invade safely, increasing map control.
Leverage Master Yi's strong dueling and objective control post-level 6 to secure dragons and Rift Heralds, snowballing leads into teamfight dominance.
