How to Play This Matchup
Power Curve
Ahri is strongest mid game while Karthus peaks late game. Play around your power window.
MR Priority
Both deal magic damage. An early Null-Magic Mantle or Mercury's Treads can swing the lane. Hexdrinker is also an option for AD champs.
Hit and Run
Ahri needs to combo and back off. Don't stay in extended trades against Karthus's sustained damage. Short trades, then disengage.
Exploit Karthus's Weakness
Karthus's main weakness: Invaded early, immobile, Zhonya's blocks R. Play around this to maximize your advantage.
Ahri Win Condition
Roam with R, pick off squishies with charm combo
Karthus Win Condition
R global damage, passive keeps dealing damage after death
