This is a scaling AP duel where Gwen must manage stacking (Q) and preserving (W) to win extended trades against Trundle's sustained melee pressure.
Gwen should avoid giving Trundle easy long trades inside his (W) zone and instead look to control fights where she can deny his outside retaliation with (W).
Trading pattern
Trade only when (Q) is stacked and (W) is available to block Trundle's retaliation and extend fights inside your mist.
Use (E) to reposition and punish Trundle if he mispositions outside of his (W) or wastes (E).
Avoid short burst trades or early all-ins without (Q) stacks and (W) ready, as Trundle thrives in extended fights inside his (W).
Danger windows
Be cautious when (W) is down as you become vulnerable to Trundle's retaliation and pillar setups.
Respect (E) pillar which can block your escape or force you into unfavorable fights.
Avoid extended trades when (R) is active on you or a nearby tank, as his stat drain makes him much harder to duel.
Early game
Focus on stacking (Q) safely early to prepare for extended trades rather than forcing short trades before your damage is ready.
Use (E) to maintain spacing and avoid getting trapped by (E) pillar or forced into his (W) zone.
Avoid committing before level 6 and before (Q) is stacked to reduce vulnerability to his early dueling and sustain.
Power spikes
At level 6, use (R) after stacking (Q) to slow and chase Trundle, turning extended trades into kills if you keep him inside your (W).
After your first AP dueling item, pressure side lanes and look for extended fights where your damage and healing outscale Trundle.
Respect Trundle's level 6 (R) which steals resistances and health; avoid extended fights during its duration to reduce his sustain and tankiness.
Win conditions
Reach your item spikes and stack (Q) fully before committing to extended trades where your healing and damage excel.
Use (W) proactively to deny Trundle's outside damage and control the fight space in side-lane duels or teamfights.
Pressure side lanes and force long fights where Trundle's mobility and burst are limited, leveraging your superior AP scaling and chase with (R).
