Sion vs Gwen Matchup Summary

The Sion vs Gwen matchup is a decisive matchup in League of Legends ranked play. Based on 47 recent matches analyzed, Sion wins with a 57.5% win rate compared to Gwen's 42.5%, giving Sion a 14.9 percentage point advantage. Sion dominates at every stage — from early laning through late game team fights. This consistent advantage makes it difficult for Gwen players to find favorable windows, so team-dependent strategies and avoiding solo confrontations are essential. The most significant statistical gap is in crowd control, where Sion leads by 1.2s CC/min — a difference that heavily influences the outcome of trades and skirmishes. Sion players can confidently pick into Gwen and play aggressively from level 1. Look to establish lane dominance early through favorable trades and zone Gwen away from CS whenever possible. Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.

Farming
7.1Sion

Damage
830Sion
1,178Gwen
Gwen heavily out-damages Sion by 347 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 Gwen's sustained damage advantage take over.
Economy
12,345Sion
12,818Gwen
Gwen earns 473 more gold per game than Sion, equivalent to roughly one additional component item. This economic edge comes from a combination of better farming, kill participation, and objective control, giving Gwen slightly faster item completions.
Utility
1.5Sion
0.3Gwen
Sion brings significantly more crowd control than Gwen, with 1.2 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. Gwen should invest in tenacity and position carefully to avoid being chain-CC'd.
Sustain
3,142Sion
1,418Gwen
Sion vastly out-sustains Gwen, healing and mitigating 1,724 more damage per minute. This massive durability gap means Sion can absorb significant punishment and remain in lane while Gwen is forced to recall.
