Based on 20 recent matches analyzed, Fiddlesticks wins with a 50.0% win rate compared to Karthus's 50.0%, giving Fiddlesticks a 0.0 percentage point advantage. Game phase dynamics play a critical role here: Fiddlesticks controls the early laning stage, but Karthus outscales as the game goes longer.
