How to Use Karthus Counter Data
Looking for reliable Karthus counters? The matchup numbers below come straight from current ranked games in the Jungle role, not from tier-list guesswork. Right now the hardest opponents for Karthus are Rammus, Evelynn, Nasus — in these matchups Karthus’s win rate drops the furthest below its average. The single strongest counter is Rammus, where Karthus wins just 41.6% of 125 recorded games. Karthus itself counters Varus, Zed, Xayah — favorable matchups worth exploiting in champion select.
Each card shows the win rate from Karthus’s perspective and the number of games behind it — a matchup with tens of thousands of games is far more trustworthy than one with a few hundred. The Easy/Even/Hard labels are computed from those win rates (below 48% reads as Hard, above 52% as Easy); they are a reading aid, not a separate source stat. Data comes from ranked games at Emerald rank and above across all regions, currently on patch 16.13.1, and refreshes automatically every 48 hours, so the numbers move with the meta. Counters are only half the picture: check the current Karthus build for the strongest items and runes, or the Karthus champion page for abilities and full details.
