Karthus vs Trundle

Updated Jun 4, 2026

Overview

Prioritize full clears to leverage Karthus's superior clear speed and avoid early river skirmishes where Trundle excels.
Focus on tracking Trundle's position to avoid his high early invade threat and counter-gank when lanes have priority.
This is a scale-oriented matchup where Karthus must protect his tempo to reach impactful global damage windows.

Jungle Plan

Execute full clears efficiently and only contest Scuttle when your lanes can support to avoid losing tempo.
Track Trundle's first river moves and be ready to counter-gank or trade camps cross-map rather than fighting isolated river battles.
Prioritize cycling camps toward your safe side and use (R) to influence fights after enemies commit or drop low, focusing on objective setups.

Danger windows

Early invade windows before level 6 when Trundle's dueling and invade resistance are high; avoid low-health river entries.
Isolated river fights where Trundle can use (E) pillar to block escape and force fights inside his (W) zone.
Forced smite fights on dragon or Herald when Trundle's sustained damage and dueling excel; only contest with lane priority and vision control.

Early game

Start with a full clear path toward safe camps to maximize level 3 health and item timing before contesting river.
Avoid early river fights unless your nearby lanes have clear priority to contest Scuttle or counter-invade.
Use wards to spot Trundle's early pathing and back off if he approaches before you reach level 6.

Power spikes

Level 6 (R) unlocks Karthus's global damage, allowing you to impact fights without direct presence; use it after enemies engage or are low.
First AP item boosts clear speed and objective damage; leverage this by cycling camps quickly and arriving early to dragons or Herald.
Respect Trundle's level 6 (R) which drains resistances; avoid extended duels and kite out its value to minimize his stat steal impact.

Win conditions

Convert fast full clears and item spikes into early objective control by arriving first and using (R) to finish low-health enemies.
Use vision and tracking to avoid Trundle's early invade attempts and punish overextensions with cross-map camp trades.
Scale into late game where your global damage and objective-area DPS can decide fights without risking isolated duels against Trundle.
