How to Play This Matchup
1
Power Curve
Karthus is strongest late game while Rengar peaks mid game. Play around your power window.
2
Mixed Resistances
Karthus deals AP damage while Rengar deals AD. Build resistances accordingly — don't stack the wrong type.
3
Sustained vs Burst
Rengar wants to combo and disengage. Karthus wins extended trades. Don't let Rengar get a clean rotation — force long fights where sustain wins.
4
Range Advantage
Karthus has range advantage. Rengar should look for short trades when Karthus uses abilities on the wave. Freeze near your tower and wait for jungle help or an all-in window.
5
Exploit Rengar's Weakness
Rengar's main weakness: No bushes = weak, CC, grouped enemies, pink wards. Play around this to maximize your advantage.
6
Karthus Win Condition
R global damage, passive keeps dealing damage after death
7
Rengar Win Condition
Bush leap combos, R stealth assassinate, snowball kills
