Dr. Mundo should focus on surviving Jayce's early ranged poke and avoid extended trades until health scaling kicks in.
Prioritize safe (Q) farming to reach key health item spikes and rely on passive crowd control block to mitigate Jayce's engage attempts.
This is a scale versus snowball matchup where Mundo aims to outlast early pressure and become an unkillable frontline.
Trading pattern
Trade only when (Q) lands repeatedly to slow Jayce and create chase or disengage space.
Use passive crowd control block to absorb Jayce's knockback engage and punish when it is on cooldown.
Activate (R) before Jayce's burst trades to sustain through poke and extend fights where Mundo's durability wins.
Danger windows
Be cautious when Jayce's empowered (Q) through (E) is available; this poke can chunk Mundo before fights.
Avoid fighting when passive crowd control block is down, as Jayce's knockback engage becomes more reliable.
Jayce's hammer (Q) commit is a danger window; back off or punish if he misses or overcommits.
Early game
Use (Q) to farm safely from distance and avoid missing cleavers to prevent Jayce's poke advantage.
Respect Jayce's empowered (Q) poke and avoid all-ins before level 6 and first health item.
Avoid extended trades early; focus on passive health regen and (W) to recover gray health after poke.
Power spikes
Level 6 (R) is a major spike; use it proactively to survive Jayce's burst and chase down low-health targets.
First health item significantly increases Mundo's damage and durability; pressure side waves and force Jayce to spend time cutting through your health.
Respect Jayce's first damage item spike where his poke and burst become more punishing; avoid unnecessary trades during this window.
Win conditions
Survive early poke by landing (Q) cleavers and using passive to block key crowd control, then scale into a durable frontline.
Reach health item spikes and use (R) healing to absorb damage and outlast Jayce in side-lane fights.
Exploit Jayce's cooldowns and mana windows to extend trades and force him to disengage, denying his lane pressure.
