Karthus
Bot Patch 26.14 · Silver and above · NA + EUW + KRBetaThis is a prototype. Nerfplz Data is still being built and tested. It reads matches through a rate-limited development key, so it sees a sample of ranked games rather than all of them, and only has one patch of history so far. Expect the numbers to move and to disagree with bigger sites until the collection matures.
That is this champion's tier based on match data alone. The written Solo Queue Tier List weighs counters, team comp synergy and matchup context on top, so the two can differ. See where the tier list puts them ↗

Short games or long games?
Karthus is at their best in shorter games and falls off the longer things drag on.
Where these numbers come from
We read finished ranked solo queue games directly from Riot and keep a running tally. Nothing is copied from another site.
Matchups compare Karthus against the enemy champion in the same lane, counting only games where both were actually there. A matchup needs a few hundred games before it is listed at all, because a 60% win rate over thirty games is noise.
Worst case is the honest version of the win rate: if the games we happened to see were a lucky sample, this is roughly the lowest the real number is likely to be. When it is still above 50%, the champion is genuinely winning.
