This is a ranged bully vs melee juggernaut matchup where Trundle must manage Quinn's poke and roam threat while forcing extended fights.
Trundle should avoid giving Quinn passive farming windows and instead pressure wave control to deny her ranged harassment and roam tempo.
Focus on splitpushing and extended duels to leverage Trundle's anti-tank and sustain strengths against Quinn's fragile, high-mobility playstyle.
Trading pattern
Trade inside (W) to maximize healing and attack speed, using (Q) to steal Quinn's attack damage and weaken her burst.
Use (E) to cut off Quinn's escape path when she commits or mispositions after using (E) for disengage.
Avoid extended trades when (W) is down or (E) is wasted, as Quinn can kite and poke effectively then.
Danger windows
Be cautious when Quinn has (E) available, as she can (E) away to avoid your engage or kite you.
Avoid fighting outside your (W) zone where Quinn can exploit her ranged poke and blind (Q).
Watch for Quinn's roams with (R); hard push to deny tower plates and ping to your team to avoid losing map pressure.
Early game
Start by controlling the wave to prevent Quinn from freely poking and setting up roams.
Avoid walking up carelessly to farm; instead, look for moments when (E) is down to engage.
Use (W) early to boost healing and trading power during short skirmishes before level 6.
Power spikes
At level 6, use (R) on Quinn if she builds tanky or on any durable target to steal resistances and health, forcing longer fights.
After your first dueling item, pressure side lanes aggressively inside (W) to punish Quinn's lower sustain and mobility.
Respect Quinn's level 6 (R) roam power by crashing waves and preparing to punish missed roams or overextensions.
Win conditions
Force extended melee duels inside (W) where Trundle's sustain and stat steal excel against Quinn's poke.
Use (E) to trap or disrupt Quinn's escape, punishing her when (E) is down.
Splitpush side lanes to pressure towers and draw Quinn out, then use (R) on durable targets in teamfights to dominate front lines and secure objectives.
