Sejuani vs Mordekaiser

Updated Jun 5, 2026

Overview

Balance full clears with controlled river moves to leverage strong engage and objective control against Mordekaiser's scaling threat.
Prioritize grouped fights and avoid isolated duels where Mordekaiser's level 6 (R) isolation can dominate.

Jungle Plan

Fight for Scuttle only when nearby lanes control river and Mordekaiser is pathing away.
Invade Mordekaiser's jungle camps with lane assistance or when he is on the opposite side to deny his scaling and objective setups.
Use vision and river control to set up dragon and Herald fights, initiating grouped skirmishes with (R) while avoiding isolated duels.

Danger windows

Mordekaiser's level 6 (R) creates strong invade and objective windows; avoid blind river checks and isolated fights during this time.
Low-health clears or using mobility and Smite before objective fights increase risk of losing forced Smite contests.
Losing lane priority around Scuttle, dragon, or Herald opens dangerous windows where Mordekaiser can force favorable fights.

Early game

Start controlled clears toward melee lanes that can follow up on (E) stun to maximize early gank threat.
Contest first Scuttle only if allied lanes have priority and Mordekaiser is tracked on the opposite side.
Avoid early invades or fights near Mordekaiser without lane priority; favor cross-map camps or opposite side ganks.

Power spikes

Level 6 unlocks (R) for long-range engage and objective fight initiation; use it to force grouped fights and deny Mordekaiser's isolation.
First tank item boosts durability and clear speed, enabling safer frontline presence and objective control.
Two completed items solidify frontline CC chains, allowing durable teamfight engage while reducing Mordekaiser's isolation impact.

Win conditions

Translate jungle tempo into objective control by securing vision and forcing grouped fights around dragon, Herald, and Void Grubs.
Deny Mordekaiser camps and scaling by tracking his pathing and counter-jungling when lanes have priority.
Use (R) and chained CC with melee allies to create picks and secure numbers advantage before objectives, avoiding isolated 1v1s.
