Quinn should use her ranged poke and high mobility to pressure Volibear and deny him safe melee access.
This is a snowball matchup where Quinn must leverage early lane pressure and roams to prevent Volibear from gaining health leads or dive opportunities.
Trading pattern
Use (Q) blind to win short trades and prevent Volibear from trading back with autos.
Avoid extended fights where Volibear can stack his second (W) heal; disengage promptly with (E) when he commits.
Punish Volibear after he uses (Q) to engage, as his follow-up threat is reduced until it is back up.
Danger windows
Be cautious when (Q) stun is available as it enables his all-in potential.
Avoid trading when (E) is down, as you lose your main disengage against his engage.
Respect Volibear's level 6 (R) dive threat, especially when you have low health or no wave to crash.
Early game
Harass Volibear frequently with (Q) and autos to punish his attempts to farm in melee range.
Hold (E) to disengage from his (Q) stun and avoid extended trades where his healing from (W) becomes effective.
Crash waves quickly to create roam windows with (R) before Volibear can build durable sustain.
Power spikes
At level 6, crash waves and use (R) to roam and create side-lane pressure before Volibear can dive.
After your first damage item, increase pressure on isolated targets using (Q) and (E) for burst and escape.
Respect Volibear's level 6 (R) dive threat and his first bruiser item timing; avoid low-health tower defense and extended trades then.
Win conditions
Win lane by denying Volibear melee access with ranged poke and using (E) to maintain spacing.
Use wave crashes to create roam opportunities with (R), applying map pressure and finding isolated picks.
Avoid grouped fights and extended brawls; instead, leverage Quinn's mobility and range to snowball and control side lanes.
