Use Trundle's strong early dueling and invade resistance to contest river and camps against Lillia's medium early pressure.
Prioritize extended fights around objectives where Trundle's stat steal and pillar control counter Lillia's mobility and sleep threat.
Jungle Plan
Full clear early camps then contest Scuttle if nearby lanes have priority to leverage pillar and (W) zone.
Invade Lillia's jungle when she is low health from fast clears or after she uses (E) sleep to punish her limited early dueling.
Use pillar to trap Lillia near objectives or narrow jungle paths and force extended fights inside (W) to maximize stat steal and healing.
Danger windows
Avoid river fights when Lillia's movement speed and (E) sleep are available, as she can kite or disengage easily.
Be cautious contesting objectives if Lillia's team has vision and can follow her global (R) sleep engage.
Low-health clears expose you to counter-invades from Lillia's fast clear speed and mobility; maintain healthy clears before fighting.
Early game
Start pathing toward river or a lane with priority to contest first Scuttle and set up early pillar traps.
Avoid fighting Lillia when her movement speed and sleep abilities are ready to kite or disengage.
Use your steady clear speed to maintain healthy health and tempo before committing to invades or counter-jungling.
Power spikes
Level 6 (R) drastically increases Trundle's dueling by stealing tank stats; prioritize ulting the highest-value tank before fights.
First dueling item completion strengthens extended side-lane fights and objective pressure; force fights inside (W) to maximize advantage.
Beware Lillia's AP scaling and sleep engage power spike post-level 6; avoid isolated fights where she can kite or sleep you.
Win conditions
Convert early dueling wins and Scuttle control into dragon and Rift Herald objectives by using pillar to trap Lillia or her teammates.
Use superior invade resistance and stat steal (R) to deny Lillia jungle camps and delay her AP scaling.
Force extended fights inside (W) and side-lane pressure to exploit Trundle's anti-tank strengths and splitpush potential against Lillia's kite-reliant kit.
