Sion vs Illaoi

Updated Jun 3, 2026

Overview

Prioritize wave control and health stacking with (W) to outscale Illaoi's zone control and tentacle pressure.
Avoid giving Illaoi free space to set up tentacles and force trades inside her zone, as she thrives in prepared areas.
This matchup favors Sion's late-game teamfight presence over Illaoi's mid-game splitpush strength; maintain lane stability to reach scaling.

Trading pattern

Use (E) slow to set up charged (Q) from fog or behind minions, punishing Illaoi when she walks forward.
Avoid visible (Q) charges and trades when (W) shield is down to prevent getting punished by Illaoi's tentacles and (E).
After Illaoi misses (E), step forward to trade aggressively before her tentacles reset and zone control returns.

Danger windows

Beware when Illaoi lands (E) near tentacles, as she can turn trades heavily in her favor.
Avoid fighting inside Illaoi's tentacle zones without (R) ready or team backup to prevent multi-target damage.
Be cautious after missing (Q) or when (W) shield is down, as Illaoi can punish these windows with tentacle slams and (R).

Early game

Focus on farming safely and using (E) to slow Illaoi before attempting charged (Q) from fog or brush angles.
Avoid extended trades early since Illaoi's tentacles and (E) create strong zone control and healing potential.
Use (W) shield to absorb poke and sustain through Illaoi's tentacle damage while stacking health for later durability.

Power spikes

At level 6, use (R) with a clear path to engage or disengage, forcing Illaoi to respect your long-range threat.
Upon reaching high health scaling with (W) stacks and tank items, absorb space and threaten charged (Q) zones to control the lane.
Respect Illaoi's level 6 (R) which can turn fights if you commit near her tentacles; avoid clustered fights without team support.

Win conditions

Deny Illaoi the ability to set up tentacles by controlling wave position and clearing her zones promptly.
Scale into a durable front line by stacking health with (W) and use charged (Q) and (R) to initiate or disrupt teamfights.
Use long-range engage (R) from fog or side angles to force Illaoi into unfavorable fights and prevent her from splitpushing safely.
