Rengar vs Sion Matchup Summary

The Rengar vs Sion matchup is a decisive matchup in League of Legends ranked play. Based on 8 recent matches analyzed, Sion wins with a 75.0% win rate compared to Rengar's 25.0%, giving Sion a 50.0 percentage point advantage. Sion dominates at every stage — from early laning through late game team fights.
