Karthus vs Kayn

Updated Jun 4, 2026

Overview

Prioritize full clears to leverage Karthus's very high clear speed and avoid early fights where Kayn's mobility and skirmishing can punish you.
Use vision and tracking to avoid Kayn's early invades and river fights, as Karthus has low invade resistance and dueling power.
Focus on scaling through efficient farming and prepare to influence fights globally once level 6 (R) is unlocked.

Jungle Plan

Use fast full clears to maintain tempo and reach key item spikes before Kayn completes his form transformation.
Contest Scuttle only when lane priority supports it, otherwise prioritize vision control and safe farming.
Track Kayn's pathing to anticipate his gank angles and counter-gank with teammates when lanes are overextended or low health.

Danger windows

Early game river fights and invades are dangerous due to Kayn's mobility and knockup; avoid low-health clears near river without vision.
Objective setups before Karthus has vision or item spikes can lead to forced smite fights that Kayn can exploit.
Kayn's wall-pathing ganks create unusual angles; maintain vision and communicate with lanes to reduce counter-gank risk.

Early game

Start with a full clear path toward safe camps to maximize tempo and avoid early Kayn skirmishes.
Only contest first Scuttle when nearby lanes have priority and can assist to mitigate Kayn's mobility and gank angles.
Avoid low-health river entries and predictable paths that Kayn can exploit with wall movement and surprise ganks.

Power spikes

Level 6 (R) unlocks global damage; keep farming tempo and use (R) to finish kills or influence fights remotely.
First AP item spike boosts clear speed and objective damage; cycle camps aggressively and secure objectives before Kayn can contest.
Kayn's form transformation is a mid-game spike; respect his increased dueling and gank threat by avoiding isolated fights and overextensions.

Win conditions

Convert fast full clears and item spikes into objective control by securing vision and forcing Kayn away from key camps.
Use (R) to impact fights globally, finishing off low-health enemies after your team initiates or after Kayn commits to a fight.
Deny Kayn's form progression by counter-jungling when safe and punishing overextensions with cross-map pressure and coordinated counter-ganks.
