Use Jarvan IV's strong level 2-3 gank pressure to create early lane leads before Viego can safely contest jungle tempo.
Prioritize invading or contesting camps early when nearby lanes have priority to punish Viego's medium invade resistance and prevent his scaling.
Leverage Jarvan IV's high objective control and engage to secure early dragons and Rift Heralds, denying Viego safe smite fights.
Jungle Plan
Path to lanes with crowd control or immobile carries to maximize (E)+(Q) engage and force early flashes on Viego.
Use early gank tempo to set up dragon or Rift Herald control, then trap Viego with (R) during contested objectives to deny his smite.
Track Viego's pathing and be ready to counter-gank his river approaches, especially around level 3-6 power spikes, to maintain tempo and scaling denial.
Danger windows
Respect Viego's threat when he gains access to river fog with (E) and can initiate skirmishes with (W) stun.
Avoid low-health clears or forced smite fights where Viego's reset execute can turn the tide.
Beware of isolated river fights before your lanes can collapse, as Viego's resets and repositioning make counter-ganking risky.
Early game
Start with a three-camp clear that leads into early gank paths on overextended or flashless lanes to force Viego onto the back foot.
Fight for first Scuttle only when your lanes can move first and collapse, as losing early river control to Viego's resets is costly.
Avoid isolated duels against Viego before level 6 unless you have lane support, as his dueling and reset potential spikes post-6.
Power spikes
At level 2-3, use (E)+(Q) to pressure lanes and force Viego off camps or flashes, leveraging Jarvan IV's early gank strength.
At level 6, use (R) to lock down Viego or his carries near objectives, preventing resets and securing kills.
Respect Viego's level 6 (R) reset potential and first fighter item timing by avoiding extended fights without lane priority or backup.
Win conditions
Convert early gank pressure and forced flashes into dragon and Rift Herald control to deny Viego scaling and map freedom.
Use (R) to trap Viego during objective fights, cutting off his smite and reset opportunities.
Track Viego's pathing to counter-jungle safely and force fights only when your lanes have priority to snowball leads into teamfight initiation and objective dominance.
