Darius jungling into Amumu should leverage early dueling strength to contest camps and deny Amumu's slower clear tempo.
Prioritize early river control and Scuttle crabs to restrict Amumu's gank angles and objective influence.
Jungle Plan
Path aggressively to invade Amumu's jungle early, especially before his first clear finishes, to deny his farm and force defensive wards.
Use your stronger dueling to secure early Scuttle crabs and control river vision for safer ganks and objective setups.
Prioritize dragon and Rift Herald control by pressuring Amumu off camps and forcing him into reactive plays.
Danger windows
Avoid isolated river fights before level 6 when Amumu's (Q) and (R) can chain crowd control and punish your low mobility.
Be cautious contesting objectives without lane priority, as Amumu's engage and team follow-up can force unfavorable smite fights.
Low-health clears expose you to counter-invades from Amumu; maintain vision and avoid overextending without backup.
Early game
Start with a three-camp clear to hit level 3 quickly and look for early invades when nearby lanes have priority.
Contest first Scuttle only if your lanes can respond to counter-ganks, otherwise focus on safe farming and vision control.
Avoid extended river fights without lane priority as Amumu's (Q) long-range engage and (R) lockdown can turn fights against you.
Power spikes
Level 6 unlocks your (R) execute, enabling lethal all-ins on low-health targets and snowballing through resets; use this to punish Amumu's weaker early dueling.
First bruiser item completion increases your durability and damage, allowing longer fights and better objective control versus Amumu.
Amumu's teamfight power spikes after he gains tank stats and (R) for lockdown; prioritize early leads before this point to avoid losing control.
Win conditions
Convert early jungle pressure and camp control into securing first dragon and Rift Herald to snowball map advantage.
Use superior dueling and invade windows to deny Amumu's farm and delay his tank scaling.
Leverage vision control and lane priority to set up ganks and counter-ganks, forcing Amumu into reactive play and preventing his grouped teamfight setups.
