Focus on controlling river Scuttle and contesting early objectives to limit Trundle's strong early dueling and invade potential.
Use your medium early game pressure and high objective control to offset Trundle's high dueling and invade resistance.
Prioritize ganks where (E) can interrupt Trundle's engage and use (R) to disrupt his positioning in skirmishes.
Jungle Plan
Prioritize pathing toward lanes where (E) can force Trundle to flash or set up kills before he can use (W) and (R) effectively.
Fight for first Scuttle only when your lanes can move first and use (R) to break enemy objective formations or deny smite access.
Counter-jungle after tracking Trundle's pathing and counter-gank his early pressure by leveraging your (E) stun and (R) displacement.
Danger windows
Beware of Trundle's early invade and river fight attempts when his lanes have priority and (W) is active.
Avoid isolated fights near his (E) pillar terrain that can trap or slow you, especially if your (E) or (R) are on cooldown.
Respect forced smite fights where Trundle's dueling and sustain can outlast you if you enter low-health clears or poor positioning.
Early game
Start with a three-camp clear to maintain health and mana, then move quickly to contest first Scuttle when nearby lanes have priority.
Avoid direct early invades against Trundle unless you have lane priority and (E) ready to disengage or punish.
Use (E) to flank or disengage in river fights and hold angles before objectives instead of walking through obvious paths.
Power spikes
At level 6, use (R) to isolate or peel targets, denying Trundle's all-in or objective control advantage; respect his (R) stat drain by avoiding extended fights during its duration.
After your first AP or tank item, leverage your improved burst or durability to win short trades and avoid prolonged duels that favor Trundle.
At level 3, use your full kit to perform short burst trades with (E) and (W), but only when passive sustain and wave state favor you.
Win conditions
Convert jungle tempo into objective control by contesting Scuttle and using (R) to disrupt Trundle's smite timing on Dragon and Rift Herald.
Use ganks where (E) can interrupt Trundle's engage or escape, leveraging your burst and displacement to secure kills and deny his side-lane pressure.
Deny Trundle's scaling by forcing short trades around your passive and (W), then use (R) to isolate him in teamfights and prevent his stat-steal advantage.
