Jax vs Amumu

Updated Jun 6, 2026

Overview

Leverage Jax's stronger early dueling power to contest camps and pressure Amumu's slower clear and weak early dueling.
Prioritize river vision and first Scuttle control to deny Amumu safe objective access and force defensive pathing.
Focus on scaling through side-lane pressure post-level 6 to exploit Jax's splitpush strength against Amumu's teamfight focus.

Jungle Plan

Aggressively path toward river Scuttle when nearby lanes hold priority to deny Amumu vision and objectives.
Invade Amumu's jungle camps after spotting him elsewhere or after he uses (Q) to exploit his low invade resistance.
Use level 6 power spike to pressure side lanes, forcing Amumu into reactive teamfights and limiting his farm.

Danger windows

Beware level 3 when Amumu's (Q) enables long-range engages combined with lane CC.
Avoid isolated river fights without vision as Amumu's (Q) and (R) can lock down targets and turn skirmishes.
Exercise caution in low-health clears or forced smite fights near objectives where Amumu's lockdown excels.

Early game

Start with a full or three-camp clear enabling quick river Scuttle contest when lanes have priority.
Avoid early fights without lane support to prevent getting caught by Amumu's (Q) engage.
Ward jungle entrances early to track Amumu's path and prepare counter-invades or safe clears.

Power spikes

Level 6 (R) grants Jax durability and damage to force extended fights and contest objectives confidently.
Two-item spike significantly boosts Jax's splitpush threat, compelling Amumu to respond and reducing his teamfight impact.
Respect Amumu's power spike when he groups with (R) for area lockdown; avoid isolated fights after this point.

Win conditions

Use superior early dueling and invade resistance to deny Amumu camps and secure first Scuttle for river control.
Convert level 6 and item spikes into side-lane pressure, forcing Amumu into unfavorable teamfights or split responses.
Control vision around dragon and Rift Herald to set picks and deny Amumu's grouped objective fights, leveraging Jax's scaling dueling power.
