Viktor vs Karthus Matchup Summary

The Viktor vs Karthus matchup is a decisive matchup in League of Legends ranked play. Based on 7 recent matches analyzed, Viktor wins with a 71.4% win rate compared to Karthus's 28.6%, giving Viktor a 42.9 percentage point advantage. Viktor dominates at every stage — from early laning through late game team fights. This consistent advantage makes it difficult for Karthus players to find favorable windows, so team-dependent strategies and avoiding solo confrontations are essential.
