Udyr vs Karthus

Updated Jun 6, 2026

Overview

Udyr's superior clear speed and dueling power let him control jungle tempo and pressure early objectives.
Prioritize invading or contesting camps when nearby lanes have priority to punish Karthus's vulnerable early clears.

Jungle Plan

Full clear fast, then invade Karthus's jungle camps when lanes have priority and he is low health from clearing.
Fight for first Scuttle only if your adjacent lanes can move first and help secure vision and control.
Use your dueling strength to deny Karthus's farming tempo and convert early leads into dragon or Rift Herald control.

Danger windows

Avoid isolated river fights early when Karthus can call for lane help or use (R) to finish low-health enemies.
Be cautious contesting objectives if Karthus has vision and can punish face-checks with repeated (Q) damage.
Watch for forced smite fights post-level 6 where Karthus's global damage can swing fights if you are below half health.

Early game

Start with a full clear to hit level 3 quickly, then look to invade or contest Scuttle if your lanes can support.
Avoid river fights if enemy lanes lack priority to prevent being collapsed on during invades.
Use your mobility to track Karthus's path and counter-invade when he shows on opposite side of the map.

Power spikes

Level 3 empowers your dueling and invade potential; push tempo aggressively before Karthus reaches level 6.
Your early item spikes increase clear and fight strength; use them to contest objectives and force Karthus off camps.
Karthus's level 6 global (R) demands avoiding extended low-health fights and punishing him before he can influence cross-map skirmishes.

Win conditions

Use your elite clear speed and dueling to deny Karthus free farm and force him off jungle camps.
Convert jungle tempo advantages into early dragon and Rift Herald control with lane priority and vision dominance.
Exploit Karthus's vulnerability to early invades by counter-jungling and forcing fights before his scaling and (R) become impactful.
