Jayce vs Sion Matchup Summary

The Jayce vs Sion matchup is a decisive matchup in League of Legends ranked play. Based on 58 recent matches analyzed, Jayce wins with a 58.6% win rate compared to Sion's 41.4%, giving Jayce a 17.2 percentage point advantage. Jayce dominates at every stage — from early laning through late game team fights. This consistent advantage makes it difficult for Sion players to find favorable windows, so team-dependent strategies and avoiding solo confrontations are essential. The most significant statistical gap is in sustain, where Sion leads by 2,350 HP/min — a difference that heavily influences the outcome of trades and skirmishes. Jayce players can confidently pick into Sion and play aggressively from level 1. Look to establish lane dominance early through favorable trades and zone Sion away from CS whenever possible. Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.

1,152Jayce
767Sion

Economy
12,349Jayce
