This matchup is a medium pressure, medium scaling duel where Trundle must force extended trades inside (W) to outstat Gangplank's poke and barrel zoning.
Trundle should deny Gangplank's passive scaling by forcing melee fights and punishing barrel setups with (E) and (R).
Trading pattern
Engage trades inside your (W) zone to maximize healing and attack speed while using (Q) to steal his damage.
Use (E) to block Gangplank's escape or barrel zones, forcing him into unfavorable positions.
Save all-ins for when (W) is active and Gangplank's barrels are cleared or on cooldown to reduce his zoning threat.
Danger windows
Be cautious when Gangplank has barrels set up near you, as his (E) chains can burst and zone effectively.
Avoid engaging when (W) cleanse is up, as it negates your crowd control and sustain advantage.
Watch for his (R) global slow during skirmishes, which can prevent your escape or chase, increasing your vulnerability.
Early game
Start by controlling the wave to avoid Gangplank setting up barrels easily and punish him when (W) is down.
Use early levels to test short trades with (Q) and (W) to build a health lead before Gangplank scales.
Avoid prolonged trades before level 6 when Gangplank's global (R) can influence fights and punish poor positioning.
Power spikes
At level 6, use (R) on Gangplank to steal resistances and health, making extended duels heavily in your favor; avoid fighting if he has his (R) active.
After your first dueling item, pressure side lanes and force trades inside (W) to capitalize on your enhanced dueling and tower threat.
Respect Gangplank's item barrel scaling and his level 6 (R) global pressure by avoiding fights when barrels are primed or (R) is available.
Win conditions
Force extended trades inside your (W) to maximize healing and attack speed, then use (Q) and (R) to drain Gangplank's damage and durability.
Use (E) to disrupt Gangplank's barrel zoning and trap him for all-ins or jungle ganks.
After gaining your first dueling item, apply side-lane pressure to threaten towers and force Gangplank into isolated fights where you excel.
