Karthus vs Master Yi

Updated Jun 4, 2026

Overview

Prioritize full clears to leverage Karthus's superior clear speed and avoid early duels with Master Yi.
Avoid early river fights unless lanes have priority, as Master Yi can punish isolated skirmishes.
This is a scale-vs-scale matchup where Karthus must protect his tempo to unlock global pressure with (R).

Jungle Plan

Focus on cycling camps efficiently to hit level 6 and first AP item faster than Master Yi.
Contest river vision and Scuttle when lanes can move first to deny Master Yi safe access to objectives.
Use cross-map camp trades when Master Yi attempts early invades, avoiding direct fights until you have item spikes.

Danger windows

Vulnerable during early clears before level 6 when Master Yi can invade and force you off camps.
Isolated river skirmishes are risky if lanes lack priority or vision control.
Objective setups without vision or lane priority expose you to forced smite fights and Master Yi's reset potential.

Early game

Start full clear away from river entrances to minimize early invade risk.
Only contest first Scuttle if nearby lanes can secure priority and assist in counter-ganks.
Track Master Yi's pathing closely and avoid low-health river entries that expose you to his medium dueling threat.

Power spikes

At level 6, use (R) to influence fights globally and finish low-health targets after skirmishes.
After your first AP item, increase camp cycling to arrive at objectives first and punish Master Yi's weaker early fights.
Respect Master Yi's level 6 (R) and item power spikes by avoiding extended low-health fights and holding CC for his engage.

Win conditions

Convert faster clear speed and item spikes into early objective control and vision dominance around dragon and Rift Herald.
Use (R) after fights start or enemies drop low to secure kills and snowball map pressure.
Deny Master Yi free farm by tracking his path and counter-jungling when he overextends or resets inefficiently.
