Shaco vs Karthus Counter Pick
Matchup Summary
What the Data Means
Two very different profiles meet in the jungle: Shaco the assassin, Karthus the mage. 415 tracked games on 16.13.1 put Shaco at a 45.1% win rate into Karthus. A deficit of 4.9 points is what earns Karthus its counter flag in this matchup.
Karthus holds a 325-unit range advantage (450 to 125), and that shapes how the matchup is traded out. That forces Shaco to play around cooldowns and pathing rather than raw stats.
Shaco threatens Hallucinate; Karthus counters through Wall of Pain. Then it becomes Hallucinate against Requiem, and the one still holding it sets the terms.
Both Shaco and Karthus threaten mainly mixed damage, so one resistance covers the matchup. Starting health splits 630 to 620 in Shaco’s favour, with armour at 30 against 21.
