Lee Sin vs Karthus

Updated Jun 4, 2026

Overview

Lee Sin should leverage his early skirmish strength to deny Karthus free farm and control river vision.
Prioritize aggressive river presence and early invades to disrupt Karthus's scaling and slow his jungle tempo.

Jungle Plan

Invade Karthus during his first clears and force him off camps before level 6 to delay his scaling.
Fight for first Scuttle only when nearby lanes have priority to ensure safe river control.
Use successful ganks to reset tempo and prevent Karthus from safely farming or contesting objectives.

Danger windows

Beware of Karthus's level 6 ultimate during isolated river fights or objective setups.
Avoid forced smite fights or extended clears when low on health, as Karthus's damage can punish you.
Watch for lanes losing priority that enable Karthus to roam or countergank effectively.

Early game

Start with a fast clear path to reach river scuttle before Karthus and secure early vision control.
Avoid risky invades before level 3 when your full kit and dueling power become available.
Use early river control to set up counter-invades or ganks on lanes where Karthus lacks priority.

Power spikes

At level 3, use your full kit to contest scuttle and force fights before Karthus completes his first clear.
At level 6, use (R) to isolate priority targets or deny Karthus's objective access.
Respect Karthus's level 6 (R) global damage and avoid extended low-health fights where he can finish kills.

Win conditions

Convert early jungle pressure into securing dragons and Rift Herald before Karthus scales.
Deny Karthus jungle camps to delay his ultimate impact and reduce his teamfight presence.
Use superior mobility and vision control to create picks and snowball lanes with timely ganks and counterganks.
