Use Diana's fast AoE clear to reach level 6 and item spikes on tempo while avoiding risky early invades against Bel'Veth.
Prioritize protecting your farming tempo and avoid fighting for Scuttle or invading before you have lane priority or level 6 to leverage your (R).
Jungle Plan
Prioritize efficient full clears and only detour for high-percentage skirmishes where you have lane priority or level 6 advantage.
Fight for river control and Scuttle when your lanes can move first and support you to secure objectives like dragon and Herald.
Use your level 6 (R) to force objective fights and convert kills into deep vision and jungle control, denying Bel'Veth's scaling.
Danger windows
Respect early invade windows when Bel'Veth has lane priority and can follow up with her knockup (W).
Avoid isolated river fights before level 6 when your (R) is unavailable and your (E) reset is less effective.
Be cautious during forced smite fights on dragon or Herald if Bel'Veth has item spikes or access to her true form (R) pressure.
Early game
Start with a full clear toward the safest reset unless a nearby lane has reliable setup for early pressure.
Avoid contesting first Scuttle unless your lanes have priority and can support you to prevent counter-invades.
Track Bel'Veth's pathing and be ready to counter-gank when she attempts early river fights or invades.
Power spikes
At level 3, use the (Q)+(W)+(E) burst combo with dash reset to punish Bel'Veth when she overextends or mispositions.
At level 6, leverage (R) to initiate or disengage fights, focusing on multi-target impact to maximize teamfight presence.
After your first AP skirmish item, pressure objectives and trades more confidently to deny Bel'Veth free farming and scaling space.
Win conditions
Convert your jungle tempo into objective control by contesting dragon and Herald with lane priority and level 6 (R) threat.
Use your burst combo and mobility to punish Bel'Veth's early farming, denying her scaling and forcing her off camps.
Coordinate with lanes to counter-gank and invade when Bel'Veth overextends or commits to extended clears, leveraging your burst and crowd control to snowball leads.
