Amumu should focus on controlled clears and avoid early fights without lane priority to survive Trundle's strong early dueling and invade pressure.
Prioritize teamfight engage and objective control after level 6, leveraging (Q) and (R) to force grouped fights and negate Trundle's splitpush threat.
Jungle Plan
Path for controlled clears and gank lanes with established priority to maximize (Q) engage impact.
Contest Scuttle Crab only when nearby lanes can move first and support river control.
Convert level 6 power spike into dragon or Rift Herald setups, using (R) to lockdown grouped enemies and secure objectives.
Danger windows
Early game river fights when Trundle has lane priority are dangerous; avoid invading or contesting Scuttle without lane support.
Isolated skirmishes before Amumu builds tank stats are risky; avoid 1v1s against Trundle's strong dueling.
Forced smite fights near dragon or Rift Herald can be lost if Trundle arrives first or traps you with (E); secure vision and approach with teammates.
Early game
Start with a full clear or three-camp clear toward a lane with crowd control to prepare for early ganks.
Avoid contesting first Scuttle Crab unless nearby lanes have clear priority to prevent getting outduelled.
Use defensive wards on jungle entrances to spot Trundle's early invades and path away if lanes cannot assist.
Power spikes
Level 6: Amumu's (R) enables strong teamfight lockdown; use it to force grouped fights and secure objectives.
Trundle's level 6 (R) steals resistances and health; avoid extended duels during its duration and punish cooldown downtime.
Trundle's first dueling item spike strengthens his splitpush and dueling; avoid isolated fights and focus on grouped objective control.
Win conditions
Survive early jungle pressure by prioritizing safe clears and avoiding unfavorable fights.
Use (Q) and (R) to force grouped fights around dragon, Rift Herald, or Void Grubs, turning teamfights in your favor.
Deny Trundle's splitpush impact by controlling river vision and objective setups, then capitalize on his cooldowns to counter-gank and secure objectives.
