Illaoi vs Heimerdinger

Updated Jun 3, 2026

Overview

Use tentacle zones to deny Heimerdinger safe turret setups and force him to farm under pressure.
Pressure early and avoid giving Heimerdinger a passive lane to prevent his turret zone control from scaling.
This is a lane pressure vs control matchup where Illaoi must break Heimerdinger's turret zones to win.

Trading pattern

Trade only when Heimerdinger walks into your tentacle zone and (E) is ready to pull his spirit.
Punish Heimerdinger heavily after (E) lands by using (W) and tentacle slams, avoiding chasing him out of zone.
Avoid trading when turrets are active and (E) is down, as Heimerdinger's poke and control are strongest then.

Danger windows

Heimerdinger is most dangerous when multiple turrets are active and (E) is ready to stun inside your zone.
Avoid committing to trades without tentacle control or when (R) is down, as ganks and turret damage become riskier.
Be cautious when walking through turret zones without (E) ready, as you can be stunned and heavily poked.

Early game

Focus on establishing tentacles around the wave early to contest Heimerdinger's turret placement.
Avoid walking into turret zones without (E) ready to prevent getting stunned or poked.
Use medium early agency to pressure Heimerdinger before he fully sets up his turrets.

Power spikes

Level 6 (R) unlocks major all-in threat; fight only inside tentacle zones and punish multi-target commits.
Establish multiple tentacles in side lanes to make Heimerdinger choose between clearing them or losing wave control.
Respect Heimerdinger's level 6 (R) upgrade that enhances his zone and burst potential, avoid extended trades then.

Win conditions

Control tentacle zones to deny Heimerdinger turret setups and force him to farm under pressure.
Land (E) to pull his spirit and force winning trades, then punish with (R) in multi-target fights.
Use side-lane pressure and anti-gank turnarounds to snowball and prevent Heimerdinger from scaling safely.
