Sett vs Illaoi

Updated Jun 3, 2026

Overview

Sett should control the lane by forcing close-range trades and denying Illaoi safe tentacle zones.
Prioritize high lane pressure to prevent Illaoi from establishing her tentacle setup and scaling safely.
This is a control vs splitpush matchup where Sett aims to disrupt Illaoi's zone and force fights on his terms.

Trading pattern

Start trades by engaging with autos and (E) to pull Illaoi near minions for a stun, then spend grit on centered (W) to maximize damage.
Punish Illaoi after she misses (E) by forcing trades before she can reposition or heal from tentacle hits.
Avoid using (W) when Illaoi can sidestep the center or when grit is low, as it reduces trade effectiveness.

Danger windows

Illaoi is most dangerous when (E) lands near tentacles, enabling strong follow-up damage and healing; avoid fighting inside her zone then.
Be cautious when (R) is available and multiple tentacles are present, as she can punish grouped trades or ganks.
Sett is vulnerable after missing (E) or spending (W) without grit; avoid extended poke or trades during these cooldowns.

Early game

Use early levels to force melee trades with autos and (E) to build grit and pressure Illaoi before she sets up tentacles.
Keep the wave close to threaten (E) stuns and prevent Illaoi from comfortably positioning for (E) spirit pulls.
Avoid extended fights without grit or when Illaoi has clear tentacle control to minimize her healing and damage.

Power spikes

Level 6: Use (R) to displace Illaoi and force favorable brawls or disengage her tentacle zones.
First bruiser item: Leverage increased durability and damage to force Illaoi into short trades or risk losing farm.
Respect Illaoi's level 6 (R) as it enables multi-target tentacle slams that can turn fights if you overcommit.

Win conditions

Win lane by forcing Illaoi into melee trades where you can stun with (E) and land grit-backed (W) for strong damage.
Use (R) after Illaoi commits to reposition her and create advantageous teamfight or side-lane pressure.
Deny Illaoi tentacle control by maintaining wave pressure and clearing tentacles to reduce her zone threat and healing.
