Prioritize safe (Q) farming and avoid extended early trades before level 6 to survive Gwen's medium early pressure.
Focus on outlasting Gwen through health scaling and (R) healing in side-lane durability fights, as this is a scale-oriented matchup with low lane pressure from Mundo.
Trading pattern
Use (Q) to poke and slow Gwen, creating space for limited trades when her (Q) is not stacked or (W) is down.
Extend trades only when (R) is active to absorb Gwen's burst and chase damage.
Punish Gwen when her (W) is down or (Q) stacks are low by stepping forward for short trades or wave pressure.
Danger windows
Be cautious when Gwen has stacked (Q) and (W) is available, as she can punish melee range and block your retaliation.
Avoid extended fights inside (W) mist, where she gains defensive stats and untargetability.
Respect (R) slow and chase during all-ins post-level 6; disengage or use (R) healing preemptively to survive.
Early game
Use (Q) to farm safely and maintain spacing, avoiding missing cleavers to prevent Gwen from punishing.
Respect (W) untargetable zone by not committing to trades when it is available.
Avoid extended trades before level 6, as Mundo's early agency is low and Gwen's mid-range damage can be punishing.
Power spikes
At level 6, activate (R) before Gwen's burst to sustain through her all-in and keep moving to mitigate her chase.
After first health item, pressure side waves to leverage Mundo's improved durability and force Gwen to spend time cutting through health.
Respect Gwen's level 6 (R) spike which adds slow and chase; avoid fights inside her (W) mist zone where she is hardest to punish.
Win conditions
Survive early lane pressure by farming reliably with (Q) and using passive to block Gwen's crowd control attempts.
Reach health-scaling item spikes and use (R) to absorb damage in side-lane fights, outlasting Gwen's burst and extended damage.
Punish Gwen's cooldowns on (W) and low (Q) stacks by stepping forward for trades and wave control to deny her scaling comfort.
