Trundle thrives in extended duels and objective fights, so prioritize fights where you can lock Rek'Sai down with (E) and drain her resistances with (R).
Rek'Sai's early gank threat is high due to mobility and knockup, so secure vision and track her tunnel paths to avoid surprise engages.
Use your strong dueling and invade resistance to contest river Scuttle and counter-invade when nearby lanes have priority.
Jungle Plan
Prioritize invading Rek'Sai's jungle after tracking her pathing and when your lanes can assist to capitalize on your superior dueling.
Fight for first Scuttle only if your nearby lanes can move first to secure vision and deny Rek'Sai's early tempo.
Use (E) to cut off Rek'Sai's tunnel escapes near objectives and force fights inside your (W) zone to maximize your sustain and damage.
Danger windows
Rek'Sai's early invade and gank pressure before level 6 is high; avoid isolated river fights without vision or lane priority.
Be cautious contesting objectives when Rek'Sai has tunnel control and nearby lanes lack priority, as she can counter-gank or escape easily.
Low-health clears or forced smite fights near Rek'Sai's tunnels increase risk; prioritize vision and avoid overextending without backup.
Early game
Start with a clear path that leads you to contest the first river Scuttle when your lanes have priority to deny Rek'Sai early tempo.
Avoid fighting Rek'Sai early if she has tunnel access and lane priority, instead focus on healthy clears to reach level 6 safely.
Use (E) near river entrances to trap Rek'Sai or block her escape during early skirmishes around objectives.
Power spikes
Level 6 is a major spike; use (R) on Rek'Sai or her nearby tanky allies to steal resistances and turn duels in your favor.
Your first dueling item completion strengthens extended fights and tower pressure; force side-lane trades inside (W) to exploit this.
Rek'Sai's early gank windows peak before level 6; respect her knockup and tunnel mobility to avoid losing tempo.
Win conditions
Convert your superior dueling and (R) stat drain into controlling dragon and Rift Herald fights by trapping Rek'Sai with (E) and forcing extended skirmishes.
Use vision control around river and jungle entrances to deny Rek'Sai's tunnel paths and limit her early gank threat.
Leverage your strong side-lane pressure post-level 6 to force Rek'Sai into reactive plays, enabling your team to secure objectives and scale safely.
