Illaoi vs Sion

Updated Jun 3, 2026

Overview

Use tentacle zones to force Sion into risky approaches and deny him safe scaling space.
Pressure early and mid lane to prevent Sion from stacking health and controlling wave with his shield.
This is a splitpush vs teamfight matchup; prioritize side-lane tentacle control to punish his engage attempts.

Trading pattern

Control tentacle space and bait Sion into walking into (E) for strong trades.
Punish Sion after he misses charged (Q) or when his (W) shield is down by committing with (R).
Do not chase; wait for Sion to commit inside tentacle range before using (W) and (R) to maximize damage.

Danger windows

Respect Sion's charged (Q) knockup from fog or brush angles; avoid predictable positioning.
Be cautious when (R) is available for long-range engage; maintain spacing and tentacle zones.
Avoid low-health fights when (W) shield is active and (R) is ready to punish mistakes.

Early game

Establish tentacles around the wave early to create zones Sion must respect.
Fish for (E) pulls when Sion tries to farm near tentacles to force short trades.
Avoid fighting without tentacles and do not chase him after slowed (E) or charged (Q) attempts.

Power spikes

At level 6, use (R) to turn multi-target fights in your favor and punish Sion's engages.
When multiple tentacles are established, pressure side lanes to force Sion to clear or lose wave control.
Respect Sion's level 6 (R) engage and his health scaling from (W) stacks; avoid extended trades when shield is up.

Win conditions

Win by controlling tentacle zones and landing (E) to force Sion into unfavorable trades.
Use (R) to punish multi-target commits and ganks that overcommit into your zone.
Deny Sion calm scaling by pressuring early and mid lane with tentacles, then splitpush side lanes to leverage your juggernaut strength.
