Rammus vs Karthus

Updated Jun 5, 2026

Overview

Rammus needs to leverage his early gank threat and mobility to disrupt Karthus's slower first clear and deny his scaling tempo.
Prioritize invading and contesting camps early to prevent Karthus from reaching his powerful item spikes and global damage windows.

Jungle Plan

Invade Karthus during his early clears to force him off camps and deny his fast farming tempo before level 6.
Use cross-map ganks on overextended lanes to capitalize on Karthus's low early gank threat and slow mobility.
Prioritize early dragon control and vision to limit Karthus's objective access and force him into teamfights where your taunt and armor scaling shine.

Danger windows

Avoid isolated river fights and early invades before Rammus's armor and taunt value become significant.
Be cautious contesting objectives when Karthus has vision and can use repeated (Q) and (E) damage to punish face-checks.
Respect Karthus's level 6 and item spikes as moments when his global damage and clear speed make him more dangerous to contest without lane priority.

Early game

Start with a three or four-camp clear aimed at lanes that are pushed or overextended to maximize gank impact before Karthus finishes his full clear.
Fight for first Scuttle only if nearby lanes have priority to avoid risky isolated river fights.
Ward defensively against early Karthus invades and be ready to counter-gank when he tries to contest river or jungle camps.

Power spikes

At level 6, respect (R) global damage by avoiding extended low-health fights and coordinate ganks to force him to use it defensively.
Exploit Rammus's taunt (E) and rolling engage (Q) power spike to punish immobile carries and deny Karthus free farm early.
Before Karthus's first AP item spike, pressure his jungle path and contest camps to delay his scaling and objective damage potential.

Win conditions

Convert early gank pressure and successful invades into dragon and Rift Herald control to limit Karthus's scaling opportunities.
Use your mobility and taunt to lock down key AD carries in teamfights, leveraging your armor scaling to absorb damage.
Deny Karthus free farm by tracking his pathing and forcing fights before he completes key items, maintaining jungle tempo and objective pressure.
