How to Use Karthus Counter Data
Need dependable Karthus matchup data? The figures below are pulled from current ranked Jungle games, not from tier-list opinions. At the moment, Rammus, Evelynn, and Nasus are the toughest lanes for Karthus, where his win rate falls furthest under his overall average. Rammus is the hardest of the three: Karthus wins only 41.6% of 125 recorded games against him. On the other side, Karthus has the edge over Varus, Zed, and Xayah, so those are worth targeting during champion select.
Every card lists Karthus’s win rate along with the sample size behind it. A matchup backed by tens of thousands of games deserves more confidence than one built on a few hundred. The Easy, Even, and Hard tags are derived from those win rates: under 48% is labeled Hard, over 52% is labeled Easy. They help with a quick read but are not a separate statistic. The data covers ranked games at Emerald and above in every region, on patch 16.13.1, and updates every 48 hours, so the results shift as the meta does. For the strongest items and runes, see the current Karthus build, or visit the Karthus champion page for ability details and the full breakdown.
