Prioritize early river control and contest Scuttle when nearby lanes have priority to leverage Trundle's strong dueling and invade resistance.
Use extended dueling power and stat-stealing (R) to dominate Gragas in prolonged fights, especially around objectives.
Focus on splitpush and side-lane pressure after securing early jungle tempo and objective control to exploit Gragas's weaker sustained dueling.
Jungle Plan
Opt for early river fights and invade weaker camps when lanes can follow to capitalize on Trundle's superior dueling.
Prioritize Scuttle control and vision around dragon and Rift Herald to deny Gragas objective access.
Use (E) to trap Gragas near objectives or narrow jungle paths, then follow up with (Q) and (R) to win extended fights and force him off camps.
Danger windows
Beware of (E) stun and (R) displacement during early river skirmishes; avoid isolated fights without lane support.
Low-health clears increase vulnerability to Gragas's burst and disengage; prioritize health and vision before contesting camps.
Forced smite fights around dragon or Herald can be risky if Gragas has cooldowns available; time objective attempts after his key abilities are used.
Early game
Start with a clear path that enables early river presence to contest or secure first Scuttle crab.
Avoid direct invades unless you have lane priority or (E) is on cooldown to reduce his escape and engage threat.
Track Gragas's pathing to counter-gank effectively, especially around level 3 when both have full basic kits.
Power spikes
Level 6 unlocks (R) to steal health and resistances, drastically increasing Trundle's dueling power against Gragas; target him or his frontline to turn fights.
First dueling item completion enhances side-lane pressure and tower sieging, enabling Trundle to force isolated fights where Gragas struggles.
Gragas's level 6 (R) displacement requires respecting his engage angles; avoid committing without vision or backup.
Win conditions
Convert early river and Scuttle control into dragon and Rift Herald advantages to snowball side-lane pressure.
Use superior dueling and (R) stat steal to deny Gragas jungle camps and scale, forcing him into reactive play.
Leverage (E) pillar to isolate Gragas or his teammates in teamfights, enabling your team to capitalize on disrupted enemy positioning.
