Prioritize full clears to leverage your superior clear speed and avoid early river fights where Warwick's dueling and sustain excel.
Focus on tracking Warwick's position to avoid early invades and counter-gank when his lanes are overextended.
This is a scaling versus early pressure matchup; your goal is to reach item spikes and use global damage to influence fights without direct dueling.
Jungle Plan
Execute full clears efficiently to reach your first item spike faster and maintain tempo advantage over Warwick.
Contest Scuttle Crab only when your lanes can move first and provide vision control to avoid Warwick's early dueling and sustain.
Focus on counter-jungling after level 6 when your global (R) can punish Warwick's overcommitment or low-health retreats, rather than fighting him directly early.
Danger windows
Be cautious around level 3 when Warwick's full kit and sustain enable strong early invades and extended duels.
Avoid isolated river fights early, especially if nearby lanes lack priority to assist or counter-gank.
Beware of forced smite fights on objectives before you have vision control and item spikes, as Warwick's sustain and dueling can overpower you.
Early game
Start with a full clear path away from river entrances to minimize early invade risk from Warwick's strong level 3 dueling.
Avoid contesting the first Scuttle Crab unless your nearby lanes have clear priority to support counter-ganks.
Use wards to track Warwick's early pathing and ping lanes to prepare for potential early river skirmishes or counter-invades.
Power spikes
At level 6, use (R) to influence fights globally and finish low-health enemies after Warwick commits or is forced out.
After your first AP item, cycle camps aggressively to arrive at objectives first and use your enhanced clear speed and damage.
Respect Warwick's level 3 power spike where his sustain and fear make extended fights dangerous; avoid early duels before your scaling kicks in.
Win conditions
Convert your faster full clears and item spikes into objective control by arriving first and using (Q) and (E) to deal sustained damage.
Use your global (R) to finish off low-health enemies after skirmishes and create pressure across the map without direct fights.
Deny Warwick tempo by tracking his pathing, avoiding early fights, and punishing his overextensions with counter-jungling and objective setups.
