Gragas vs Karthus

Updated Jun 4, 2026

Overview

Use Gragas's medium early pressure and strong gank threat to disrupt Karthus's slower, full-clear focused jungle tempo.
Prioritize river control and objective setup to prevent Karthus from safely farming and scaling into his global damage windows.

Jungle Plan

Invade Karthus during his first clears to force him off camps before level 6 and deny his fast full-clear tempo.
Prioritize river control and contest Scuttle when lanes can move first to set up dragon and Rift Herald.
Use (E) flank angles to gank lanes where you can force flashes or kills, then leverage (R) to disrupt enemy objective formations.

Danger windows

Beware early invade attempts from Karthus when lanes lack priority; avoid isolated river fights without vision.
Avoid low-health clears where Karthus can punish with (R) or collapse from lanes.
Objective fights are risky if Karthus can stack (Q) and (E) damage; hold (R) to disrupt his positioning and smite timing.

Early game

Start with a three-camp clear if lanes can assist to enable early invade or Scuttle contest.
Contest first Scuttle only if nearby lanes have priority to avoid getting collapsed on.
Avoid direct fights early if Karthus paths predictably for full clears; instead, track him and prepare counter-ganks.

Power spikes

Level 6: Use (R) to isolate or disengage, forcing Karthus to respect your displacement and limiting his global impact.
First AP or tank item: Trade around your increased burst or durability to pressure Karthus before he finishes his item.
Respect Karthus's level 6 (R) global damage by avoiding extended low-health fights and staying grouped when possible.

Win conditions

Convert early invade and Scuttle control into dragon and Rift Herald priority to deny Karthus safe farming.
Use your gank threat and displacement (E) and (R) to pressure lanes, force Karthus off camps, and delay his scaling.
Leverage (R) in teamfights to isolate Karthus or peel for carries, minimizing his global damage impact and securing objectives.
