Use Nunu & Willump's superior objective control and gank threat to pressure early dragons and Heralds before Vi can leverage her strong dueling power.
Avoid isolated duels with Vi; instead, rely on lane priority and (W) angles to create numbers advantages for ganks and objective setups.
Jungle Plan
Prioritize pathing that enables early ganks where lane CC or flashes are down, then immediately transition to dragon or Rift Herald if lanes have priority.
Contest river vision and Scuttle only when your lanes can respond quickly to Vi's pressure or counter-gank attempts.
Track Vi's pathing to counter-gank her early ganks, especially after she uses (Q) for engage, and avoid fighting her alone without lane support.
Danger windows
Respect Vi's early level 3 when her (Q) and basic attacks make her a strong duelist capable of punishing isolated clears.
Avoid isolated river fights before your lanes have priority, as Vi can force smite fights with her lockdown (R).
Be cautious during low-health clears or when forced into smite contests without lane support, as Vi's dueling and objective control can overwhelm you.
Early game
Start with a fast clear using (Q) to maintain high tempo and look to contest first Scuttle only if nearby lanes have priority.
Avoid early invades against Vi unless you have lane priority and vision control to prevent her from punishing your isolated clears.
Use (W) from fog to approach lanes for early ganks, forcing Vi to play more cautiously and ward deeper than usual.
Power spikes
At first dragon or Herald spawn, use (Q) plus Smite to secure objectives quickly and force Vi into reactive plays.
At level 6, layer (R) after (W) or allied CC to maximize zone control and punish Vi when she commits with her (R) lockdown.
Respect Vi's early level 3 power spike when her (Q) dash knockback can enable strong dueling and gank pressure.
Win conditions
Convert successful early ganks into immediate dragon or Herald starts to build objective leads and map pressure.
Use (W) gank angles and (Q) sustain to maintain jungle tempo and deny Vi safe farming or uncontested objectives.
Force cross-map plays and counter-jungle when Vi shows on the opposite side, leveraging your superior objective control and team utility to snowball leads.
