Sion vs Illaoi Matchup Summary

The Sion vs Illaoi matchup is a moderate matchup in League of Legends ranked play. Based on 42 recent matches analyzed, Illaoi wins with a 52.4% win rate compared to Sion's 47.6%, giving Illaoi a 4.8 percentage point advantage. Game phase dynamics play a critical role here: Illaoi controls the early laning stage, but Sion outscales as the game goes longer. The matchup shifts dramatically depending on game length — Illaoi needs to press advantages before Sion reaches their power spikes, while Sion should focus on safe farming and hitting key item breakpoints. The most significant statistical gap is in crowd control, where Sion leads by 1.5s CC/min — a difference that heavily influences the outcome of trades and skirmishes. While Illaoi is slightly favored, Sion can absolutely win this lane through smart trading patterns and wave management. Focus on playing around your cooldowns, conceding CS only when necessary, and capitalizing on Illaoi's mistakes. Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.

Damage
792Sion
1,330Illaoi
Illaoi heavily out-damages Sion by 538 DMG/min, dominating both short trades and all-in fights. Sion should avoid extended combat and instead focus on burst trade patterns — short engages followed by immediate disengagement — to avoid letting Illaoi's sustained damage advantage take over.
Economy
10,318Sion
11,605Illaoi
Illaoi generates a commanding 1,287 more gold per game than Sion. This substantial economic advantage means Illaoi consistently reaches key item breakpoints earlier, creating a compounding lead that grows throughout the game.

Utility
1.9Sion
0.4Illaoi
Sion brings significantly more crowd control than Illaoi, with 1.5 more seconds of CC per minute. This large utility gap makes Sion far more valuable in setting up jungle ganks, controlling objectives, and locking down targets in team fights.

Sustain
3,083Sion

Sion vastly out-sustains Illaoi, healing and mitigating 1,070 more damage per minute. This massive durability gap means Sion can absorb significant punishment and remain in lane while Illaoi is forced to recall.

Illaoi dominates the early game (first 15 minutes) with a commanding 60.0% win rate — a 20.0 percentage point lead over Sion. This lopsided early game means Illaoi can dictate the pace of the lane from level 1, controlling trades, wave state, and river priority.

Sion is far superior in the late game (25+ minutes), boasting a 54.5% win rate — 9.1 points above Illaoi. Extended games heavily favor Sion, whose kit and scaling make them a dominant force in team fights and objective control.

This matchup features a dramatic power shift: Illaoi must aggressively press their early advantage and close out the game before Sion reaches their scaling breakpoints. If Sion survives the laning phase without falling too far behind, the matchup flips in their favor. Dragon and Rift Herald control are pivotal — the team that secures early objectives can snowball or buy time to scale.
