Illaoi vs Gragas

Updated Jun 3, 2026

Overview

Use tentacle zones to force Gragas into risky (E) angles and deny him safe short trades.
Prioritize lane pressure and tentacle control to prevent Gragas from leveraging his burst and sustain for passive lane control.

Trading pattern

Fish for (E) spirit pulls to force committed trades where tentacles amplify damage.
Avoid extended fights when (E) is on cooldown to reduce risk from Gragas's burst and sustain.
Punish Gragas after he wastes (E) by stepping forward with tentacle pressure and (W) empowered slams.

Danger windows

Respect (E) stun threat, especially when he can engage from fog or close range.
Be cautious when (R) is down, as ganks and all-ins become safer for Gragas.
Avoid fighting without tentacles nearby, as Gragas can capitalize on Illaoi's low mobility and burst windows.

Early game

Establish tentacles early around the wave to create zones Gragas must respect before level 6.
Avoid chasing Gragas aggressively early to not get stunned by (E); instead, bait his engage to punish with (E) spirit pulls.
Use (Q) and (W) combos only when Gragas is forced into tentacle range after missing his (E).

Power spikes

Level 6 (R) greatly increases Illaoi's all-in threat; fight only inside tentacle zones and use (R) when Gragas commits.
Side-lane with multiple tentacles established creates a strong zone that forces Gragas to choose between wave control or risking (E) pulls.
Respect Gragas's level 6 (R) displacement to avoid being knocked out of tentacle range or into dangerous positions.

Win conditions

Control tentacle zones and force Gragas to walk into (E) to win trades and lane pressure.
Use (R) to punish multi-target commits or ganks that cluster near tentacles.
Deny Gragas safe short trades by maintaining tentacle presence and forcing him to clear them before farming or pushing.
