Mordekaiser vs Illaoi

Updated Jun 3, 2026

Overview

Mordekaiser aims to control the lane through medium pressure and extended trades, denying Illaoi safe tentacle zones.
This is a control matchup where Mordekaiser must manage Illaoi's high lane pressure and avoid giving her free all-ins inside tentacle setups.

Trading pattern

Start trades by threatening or landing (E) to pull Illaoi into your passive and isolated (Q) damage.
Avoid engaging if (E) misses or Illaoi has tentacles nearby ready to slam.
Extend trades only when your (W) shield is charged and passive damage is active to outlast Illaoi’s burst.

Danger windows

Be cautious when Illaoi lands (E) near tentacles as her damage and healing spike, making trades lethal.
Avoid fighting inside Illaoi’s tentacle zones without (R) ready, as she punishes committed melee trades heavily.
After missing (E), your engage threat drops significantly; Illaoi may punish if you overextend without pull threat.

Early game

Use early waves to threaten (E) pulls and force Illaoi to respect your zone to prevent her from establishing tentacles.
Avoid committing to trades before level 6 when you cannot isolate Illaoi or force extended fights.
Keep wave slow and near your side to maintain threat range and prevent Illaoi from freely setting tentacles.

Power spikes

At level 6, use (R) to isolate Illaoi and force duels away from her tentacles; avoid blind realm use if she can kite.
After your first AP bruiser item, force longer trades to leverage your sustained damage and shield healing.
Respect Illaoi’s level 6 (R) and tentacle zones as she can turn multi-target fights in her favor; avoid clustered fights near her tentacles.

Win conditions

Use wave control and (E) pressure to force Illaoi into extended trades where your passive and (W) shield win fights.
At level 6, isolate Illaoi with (R) to remove her tentacle support and secure kills or force summoners.
Deny Illaoi safe tentacle setups by controlling wave position and punishing her when (E) or tentacles are down to maintain lane dominance.
